Problems to be solved by the invention

[0004] However, in Patent Documents 1 and 2, a permanent magnet is provided outside the outer pipe, for example, held in a case made of resin, and magnetizes the outside air by these permanent magnets. For this purpose, it is necessary to use a very strong and expensive permanent magnet, and even if such a high-priced magnet is used, since the outside air is not magnetized well, the thermal decomposition is not performed well, which is the worst. In some cases, it was necessary to remove all the waste in the pyrolysis chamber and restart the equipment.

[0005] The present invention has been made paying attention to such problems, and by stably magnetizing the outside air flowing into the thermal decomposition chamber, it is possible to obtain a stable thermal decomposition operation state. An object of the present invention is to provide a magnetic field pyrolysis apparatus that can do this.

Means for solving the problem

[0006] In order to solve the above problem, a magnetic field pyrolysis apparatus according to claim 1 of the present invention provides: A thermal decomposition chamber is formed and a heat-resistant container made of a heat-resistant member, a plurality of external airflow inlets provided on the side wall of the heat-resistant container, and each external airflow inlet is led out, and external air can be taken in from the end An external pipe line, a permanent magnet provided on the external pipe line, and an exhaust path communicating with an upper position of the pyrolysis chamber, and the outside magnetized by the permanent magnet In the magnetic field pyrolysis apparatus for letting the waste introduced into the pyrolysis chamber into the pyrolysis chamber by natural intake air, the permanent magnet is a ring-shaped magnet, and the ring It is characterized in that a magnet is inserted into the outer pipe.

According to this feature, by inserting the ring-shaped magnet into the outer conduit, the outside air passing through the outer conduit passes through the ring-shaped magnet in a state of being in contact with or very close to the conventional one. Compared to the case where a pair of permanent magnets are arranged outside the external pipe, even with an inexpensive permanent magnet with a low magnetic force, the outside air can be magnetized well, and thus stable thermal decomposition operation status can be achieved. Obtainable.

As a result, a larger magnetic field vibration can be applied to the outside air, and adjacent ring magnets are inserted so that the opposite faces have different poles, so that magnetic flux also exists between these adjacent ring magnets. As the outside air passes between these ring magnets, the magnetizing process is performed, so that it is possible to apply a large magnetic field vibration by the magnetizing process without filling the outside air efficiently. Furthermore, it is possible to obtain a defined operating state of thermal decomposition.

Depending on the size of the intake opening, the total amount of outside air flowing into the thermal decomposition treatment chamber through multiple external pipes can be controlled to exceed the predetermined upper limit, so thermal decomposition can be performed. In addition to preventing the ignition of waste due to excessive outside air flowing into the processing chamber, the outside air flowing into the chamber section varies depending on the thermal decomposition state near the outside air flow inlet where each external pipe is led out. Heat distributed to the external pipe Since flows into the processing chamber, as in the prior art, the amount of outside air flowing in from the outside line, there is no need to adjust individually sequentially by valves or the like.

Therefore, when these wastes are introduced into the pyrolysis chamber from the internal inlet, it is possible to prevent a large amount of outside air from flowing from the internal inlet into the pyrolysis chamber. As a result, it is possible to prevent ignition of the waste during the pyrolysis process due to the inflow of outside air and to continuously introduce new waste without greatly affecting the state of pyrolysis.

BEST MODE FOR CARRYING OUT THE INVENTION

Examples of the present invention will be described below.

Example

An embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a perspective view showing an overall image of a magnetic field pyrolysis apparatus 1 in an embodiment of the present invention.

As shown in FIG. 1, the magnetic field pyrolysis apparatus 1 of the present embodiment has a heat-resistant container 2 that has a vertically long cylindrical shape, and a mode that protrudes from the side surface of the heat-resistant container 2 on the front surface of the heat-resistant container 2. It consists mainly of an input part 3 for inputting waste.

[0019] As shown in Fig. 5 (C-C cross section), the heat formed in the inside of the heat-resistant container 2 is formed on the lower outer periphery of the heat-resistant container 2 of the present embodiment, as shown in Fig. 5 (C-C cross section). External pipe lines 20a-p led out from a plurality of outside air inlets 17a-p formed in the side wall of the heat-resistant container 2 so as to communicate the decomposition treatment chamber 30 and the outside of the heat-resistant container 2, and An outside air intake section having two chambers 15 and 18 is provided, and an ash discharge port 32 for taking out magnetized ash deposited at the lowermost part of the thermal decomposition treatment chamber 30 is provided. The ash outlet 32 can be opened and closed. The ash outlet door 32 ′ is closed except when the magnetized ash is taken out.

[0020] In addition, an iron circular top plate 5 is welded to the heat-resistant container 2 at the upper end of the cylindrical heat-resistant container 2, and the inside of the heat-resistant container 2 is in a substantially hermetically sealed state. 30.

[0021] As shown in the enlarged circle of Fig. 2, the heat-resistant container 2 used in this example is a double-layered hollow having a hollow portion 2c between the outer steel plate 2a and the inner steel plate 2b. The thermal decomposition chamber 30 is thermally insulated from the outside by introducing the magnetized ash taken out from the ash discharge port 32 into the hollow portion 2c as a heat insulating material. It is configured so that the internal heat is difficult to escape to the outside.

In the present embodiment, the heat-resistant container 2 has a cylindrical shape. This is because, in a conventional magnetic field pyrolysis apparatus having a square box-shaped pyrolysis chamber, a corner in the pyrolysis chamber is provided. In order to decompose the remaining undecomposed waste locally, unexposed waste remains locally in the corners of the thermal decomposition chamber. In addition, it is necessary to move the undecomposed waste at the corner to the center of the thermal decomposition chamber, which is cumbersome and takes time to process the undecomposed waste at the corner. Therefore, it is preferable that the efficiency of the thermal decomposition treatment can be reduced, but the present invention is not limited to this. The shape of the heat-resistant container 2 is subjected to the decomposition treatment. Select appropriately according to the amount and type of waste to be treated. Just do it.

[0023] At the center of the circular top plate 5 of this embodiment, as shown in Figs. 2 and 3, a cylindrical pyrolysis is performed so that the interior of the pyrolysis chamber 30 is divided into upper and lower spaces. A through-hole 5 ′ is provided through which a partition plate shaft 10 fixed at the center of a circular partition plate 12 having a size substantially inscribed in the processing chamber 30 is movably moved up and down.

[0024] A connection shaft 8 connected in a T-shape is connected to the upper end portion of the partition plate shaft 10 so as to be orthogonal to the partition plate shaft 10, and both of the connection shafts 8 are connected. The end is connected to the cylinder shafts 6a and 6b of the two hydraulic cylinders 4a and 4b provided at opposite positions on the outer peripheral surface of the heat-resistant container 2, and controls the hydraulic pressure supplied to the hydraulic cylinders 4a and 4b. As a result, the partition plate 12 can be moved up and down, and waste to be treated in the pyrolysis chamber 30 can be pressurized by the lower surface of the partition plate 12. ing.

[0025] In addition, two exhaust ports 28 are formed at opposing positions on the outer peripheral surface near the upper end of the heat-resistant container 2, and the rear surface position of the outer peripheral surface of the heat-resistant container 2 (the input portion 3 is disposed). As shown in FIG. 3, a water treatment device 7 for treating the exhaust water is fixedly installed at a position opposite to the upper side of the heat-resistant container 2 along the outer peripheral surface near the upper end of the heat-resistant container 2. By connecting the water treatment device 7 and the exhaust port 28 through the exhaust pipe 11, the decomposition gas (dry distillation gas) discharged from the exhaust port 28 flows into the water treatment device 7 and the water After being treated in a treatment water tank formed inside the treatment device 7, the water is exhausted from an exhaust chimney 9 erected on the upper surface of the water treatment device 7.

Next, the input unit 3 used in the present embodiment will be described with reference to FIG. 3. The input unit 3 includes a vertical passage 42 through which waste is pumped, and the transported waste is horizontal. A transverse passage 35 that is moved in the direction, and the transverse passage 35 is connected to an internal charging port 31 formed on the outer peripheral surface of the upper part of the heat-resistant container 2. The vertical passage 42 and the horizontal passage 35 are formed as a closed space by the box-shaped housing 3 ′.

[0027] That is, the space facing the internal insertion port 31 is the horizontal passage 35 and the vertical passage 42 closed by the box-shaped housing 3 ', and the horizontal passage 35 and the vertical passage 42 are used in the present invention. An input room is formed.

[0028] And, on the side surface of the vertical passage 42, which is the lower position of the heat-resistant container 2, an external inlet 13 having an external opening / closing door 14 is provided, and at the lower end position of the vertical passage 42. The lifting device 39 having the lifting table 38 is installed so that the height position force of the lifting table 38 in the most contracted state of the lifting device 39 is substantially the same height as the lower end position of the external input port 13. The operator can input the waste from the external input port 13 onto the lifting table 38, and the input waste is transferred into the vertical passage 42 by the lifting device 39. Is transported to the level of the side passage 35.

[0029] Further, as shown in FIG. 3, the transfer device having the transfer plate 36 at the end position of the lateral passage 35 on the side opposite to the internal charging port 31 is the same as the above-described transfer device 39. 37 is provided, and the waste transported by the transporting device 39 is transferred to the internal input port 31 side by the transfer plate 36 and input into the thermal decomposition treatment chamber 30. [0030] It should be noted that an internal opening / closing door 33 for opening and closing the internal charging port 31 is provided at a position immediately before the internal charging port 31 of the lateral passage 35 so as to be slidable in the vertical direction. In the vicinity of the door 33 on the side opposite to the inner charging port 31, there is an exhaust valve 40 capable of discharging the air inside the side passage 35 to the outside without flowing outside air into the side passage 35. It is provided at the upper position of 35.

[0031] On the surface (inner surface) side of the internal opening / closing door 33 of the present embodiment on the side of the thermal decomposition treatment chamber 30, an engaging piece 34 is projected, and when the partition plate 12 is raised, When the engagement piece 34 is engaged with the upper surface of the partition plate 12, the internal opening / closing door 33 is slidably opened and closed in conjunction with the rising of the partition plate 12.

[0032] The partition plate 12 used in the present embodiment is provided with a plurality of vent holes 25 concentrically penetrating in the thickness direction of the partition plate 12, as shown in FIG. The cracked gas generated in the thermal decomposition treatment chamber 30 below the partition plate 12 is discharged through the vent holes 25 to the decomposition gas treatment space 30 ′ formed above the partition plate 12. Each of these vent holes 25 is provided with a ring-shaped magnet 26 which is a ring-shaped permanent magnet, and a cracked gas treatment space 30 for harmful substances contained in the cracked gas passing through these vent holes 25. Resolving power at 'is promoted by the magnetizing treatment by these ring magnets 26.

In this embodiment, these partition plates 12 are made of heat-resistant steel from the viewpoint of heat resistance and strength. However, the present invention is not limited to this. Any material that has sufficient heat resistance and mechanical strength can be used.

In this way, the provision of the ring-shaped magnet 26 in the vent hole 25 is that most of the cracked gas generated in the thermal decomposition treatment chamber 30 is passed through the vent hole 25 through the cracked gas treatment space 30 ′. Since most of the decomposed gas can be magnetized, the ring-shaped magnet 26 is used as a magnet for the magnetizing process, so that the decomposed gas and the magnet Therefore, it is possible to effectively magnetize the cracked gas passing therethrough.

[0035] Further, in the present embodiment, as the ring-shaped magnets 26, magnets having N poles and S poles in the thickness direction are used. Case and Similarly, since the density of magnetic lines of force at the inner diameter of the ring-shaped magnet 26 through which cracked gas passes can be increased, other magnets, for example, semicircular magnets corresponding to the semicircular portion of the ring as shown in FIG. Compared to the case where a ring-shaped magnet is formed using two magnets, sufficient magnetization processing can be performed without using a magnet with a large magnetic force.

Next, the outside air intake part of the magnetic field pyrolysis apparatus 1 of this embodiment will be described with reference to FIG. 5. The outside air flow inlets 17a to 17p are located at positions below the outer peripheral side surface of the heat-resistant container 2 of this embodiment. However, they are drilled at approximately equal intervals in the outer circumferential direction at substantially the same height position. Then, external pipe lines 20a to 20p are connected to the external air flow inlets 17a to 17p, respectively.

[0037] Of these external pipes 20a-p, half of the external pipes 20a-d, 20m-p are connected to the same chamber 15 in the shape of a hollow square box and become the other half. The external pipe lines 20e to 20l are connected to another chamber 18 provided at a position opposite to the chamber 15.

[0038] In other words, the length of the external pipe connected to the external air flow inlet near the chambers 15 and 18, for example, the external pipes 20a, i is short, and the external pipe connected to the external air inlet far from the chambers 15 and 18 is connected. The length of external pipes such as external pipes 20m, e will be longer. The outer pipe line having a short path length is formed concentrically with the outer peripheral surface at a position close to the outer peripheral surface of the heat resistant container 2.

[0039] The lower surfaces of the chambers 15 and 18 are larger in diameter than the outer pipes 20a to 20p, and have a predetermined size based on the maximum amount of outside air flowing into the pyrolysis chamber 30. The outside air inlets 16 and 19 are formed, and the outside air that has flowed into the chambers 15 and 18 from the outside air inlets 16 and 19 is supplied to the outside air inlets 17a to 17p through the external pipes 20a to 20p. Into the pyrolysis chamber 30.

[0040] Then, as shown in FIG. 5 and FIG. 6, a ring-shaped magnet 50, which is a ring-shaped permanent magnet, is inserted in each of the external pipes 20a to 20p. Specifically, in the present embodiment, the ring-shaped magnet 50 is arranged so as to be within one line with respect to a predetermined road length, and the short lengths 20a, 20b, 20h, 20i, 20j, 20p, 1 ring magnet 50 force inserted, then 20m, 20g, 20k, 20o f, 2 path lengths, 20d, 20f, 201 In the case of 20η, three ring magnets 50 are inserted, and in the case of 20m, 20e with the longest path length, four ring magnets 50 are inserted.

These ring-shaped magnets 50 have an outer diameter that is substantially the same as the outer diameter of the main pipe 51 that forms the outer pipes 20a to 20p, and the inner diameter is larger than the inner diameter of the main pipe 51. Small diameter It is said that.

Then, as shown in FIG. 6, these ring-shaped magnets 50 are arranged between two main pipes 51 having a predetermined length inside a joint pipe 52 having an inner diameter slightly larger than the outer diameter of the main pipe 51. The outer pipes 20a-p in which the ring-shaped magnets 50 are inserted are formed by adhering the inner circumferential surface of the joint pipe 52 and the outer circumferential surface of the main pipe 51 while maintaining the clamping state.

[0043] As the material of the main pipe 51 and the joint pipe 52, resin pipe materials that are relatively excellent in workability and are not magnetized by the ring-shaped magnet 50 can be suitably used. Since the joint pipe 52 is exposed to the outside and is not significantly affected by the heat of the heat-resistant container 2, a pipe made of salty vinyl resin is used in this embodiment.

As described above, in this embodiment, the ring-shaped magnet 50 having an inner diameter smaller than the inner diameter of the main pipe 51 is used, and this is done as shown in FIG. 7 (a). When outside air passes through the inner diameter of the ring-shaped magnet 50, turbulent flow is generated in the passing outside air, which is preferable because large magnetic vibration can be imparted to the passing outside air. The present invention is not limited to this, and the inner diameter of the ring-shaped magnet 50 and the inner diameter of the main pipe 51 may be set to substantially the same diameter.

In the present embodiment, as shown in FIG. 7 (b), the ring-shaped magnet 50 has N and S poles in the thickness direction of the ring-shaped magnet 50, as in the case of the ring-shaped magnet 26. In this way, the density of magnetic lines of force at the inner diameter of the ring-shaped magnet 50 through which the outside air passes can be increased, so that a ring-shaped magnet using two semicircular magnets as shown in FIG. Compared to the above, sufficient magnetization processing can be performed without using a magnet having a large magnetic force.

[0046] Further, the ring-shaped magnet 50 having the N-pole and the S-pole in the thickness direction is placed so that the opposing surfaces of the ring-shaped magnet 50 in contact with the P are different poles, so that these ring-shaped magnets Since the magnetic field lines are interposed between the adjacent ring-shaped magnets 50 and between the adjacent magnets 50, the magnetizing process further proceeds.

[0047] In addition, the normal magnetic field pyrolysis apparatus does not require power for operating the blower motor or the like because the outside air is taken into the pyrolysis chamber 30 by natural intake air, but the magnetic field of this embodiment is not necessary. As described above, the field pyrolysis apparatus 1 includes the hydraulic pump 62 for supplying hydraulic pressure to the hydraulic cylinders 4a and 4b for raising and lowering the partition plate 12, and the hydraulic pump 62 for supplying hydraulic pressure to the hydraulic cylinders 4a and 4b. The hydraulic control valve device 65 that releases the hydraulic pressure supplied from the hydraulic cylinders 4a and 4b, the above-described lifting device 39, and the control computer that controls the operation of each part are connected to the transfer device 37. An internal control device 60 is provided, and the control device 60 performs operation control according to the operation of various operation switches provided on the operation panel 61.

Hereinafter, the operation status of the magnetic field pyrolysis apparatus 1 of the present embodiment will be described below. First, when operating the magnetic field pyrolysis apparatus 1 of the present embodiment, a prescribed amount of water is poured into the water treatment apparatus 7 in advance.

[0049] Then, first, the magnetized ash recovered from the other magnetic field pyrolysis apparatus 1 is thrown into the entire bottom surface of the pyrolysis chamber 30 so as to be deposited with a thickness of about 50 mm. Heat with a heater. It should be noted that these magnetized ash can be charged and heated with the ash outlet 32 opened.

[0050] On top of that, easy-to-treat waste, such as dried ogattaz, rice husks, or dead leaves, is put. It should be noted that such easy-to-treat waste may be input with the ash outlet 32 open.

[0051] Then, waste such as plastic having a relatively low water content is put into the upper part. Specifically, waste such as plastic with a relatively low moisture content is thrown from the external door 14 onto the lifting table 38 in the vertical passage 42, and then the external door 14 is closed. Operate the input button switch provided on panel 61.

[0052] In response to this operation, the control device 60 operates the lifting device 39 to raise the lifting table 38 to the lower surface position of the lateral passage 35, and then operates the transfer device 37 to move the lateral direction. The waste pumped in the passage 35 is transferred to the internal inlet 31 side.

[0053] When the transfer device 37 operates and the transfer plate 36 moves, the waste is compressed between the internal open / close door 33 and the transfer plate 36 which are not opened, and the waste is thrown into the input waste. As a result, the air contained in the waste is exhausted from the exhaust valve 40.

[0054] After these compression processes, the control device 60 operates the hydraulic pump 62 and controls the hydraulic control valve device 65 to supply hydraulic pressure to the hydraulic cylinders 4a and 4b. The plate 12 is raised and the internal door 33 is slid upward. [0055] Then, after the internal opening / closing door 33 is opened, the transfer device 37 is operated again to move the transfer plate 36, so that the waste having a relatively low water content is compressed into the internal inlet. It is thrown into the pyrolysis chamber 30 from 31.

[0056] After these inputs, the control device 60 controls the hydraulic control valve device 65 to release the hydraulic pressure applied to the hydraulic cylinders 4a and 4b, thereby simultaneously lowering the partition plate 12. By closing the internal opening / closing door 33, the partition plate 12 that has been lowered causes the waste having a relatively low water content that has been thrown into the pyrolysis chamber 30 to move downward in the pyrolysis chamber 30. It is deposited to be pushed.

[0057] The introduction of the waste having a relatively low moisture content is repeated as appropriate to form a waste layer having a relatively low moisture content in the thermal decomposition treatment chamber 30, and then the treatment described above. After igniting ogataz, rice husks, or dead leaves, which are easily discarded, from the ash outlet 32, close the ash outlet 32 when ignition is confirmed.

As described above, after the ash discharge port 32 is closed, conventionally, the amount of the magnetized outside air flowing into the pyrolysis chamber 30 from the outside air flow inlets 17a to 17p is individually controlled by a valve or the like. However, in the magnetic field pyrolysis apparatus 1 of the present embodiment, the total force of the magnetized outside air flowing into the pyrolysis chamber 30 from the outside air inlets 17a-p into the outside air intake port 16 The amount of outside air restricted by the size of 19 is appropriately distributed to each external pipe 20a-p according to the state of thermal decomposition in the vicinity of each outside air flow inlet 17a-p. Then, by flowing into the pyrolysis chamber 30, the amount of magnetization-treated outside air flowing from each of the outside air flow inlets 17a to 17p is automatically adjusted. Depending on the state of thermal decomposition in the vicinity of each external airflow inlet 17a-p in the thermal decomposition treatment room 30 The amount of magnetized outside air flowing in from the air flow inlets 17a to 17p need not be sequentially adjusted by a valve or the like, and the troublesome adjustment by these valves or the like can be eliminated.

[0059] Then, the heat generated by the combustion of the ignitable waste that is ignited, the magnetized ash that has been input, and the magnetized outside air supplied from the outside air intake section are used to generate heat. Waste having a relatively low water content that has been put into the decomposition chamber 30 is subjected to thermal decomposition.

[0060] In the initial stage of operation immediately after the start of these operations, the moisture content is relatively low. As described above, waste is gradually introduced through the external door 14 and, as the operation becomes stable, waste with a relatively high water content is gradually increased.

[0061] Thus, when a new waste is input during operation, as described above, the waste to be input is compressed in advance before being input into the thermal decomposition treatment chamber 30. As a result, air gap reduction and deaeration are performed, and even if the internal opening / closing door 33 that closes the internal insertion port 31 is opened, the space facing the internal insertion port 31 remains in the box-shaped housing 3 ′. Therefore, when these wastes are introduced, the outside air that has not been magnetized is excessively flowed into the pyrolysis chamber 30, so that the pyrolysis chamber 30. It is possible to carry out stable waste disposal that does not adversely affect the pyrolysis of fire.

[0062] Furthermore, after the compression processing, the partition plate 12 also falls in the thermal decomposition treatment chamber 30 when the re-absorbed waste is released from the compression at the time of introduction from the internal charging port 31. Then, by compressing the newly introduced waste from above, it is exhausted to the cracked gas treatment space 30 ′ through the vent hole 25, and the newly introduced waste and the already introduced waste are already introduced. By reducing the size of the gap between the waste and the waste, and the presence of outside air containing oxygen in these gaps, the pyrolyzed waste already in the pyrolysis chamber 30 is ignited. It is possible to suppress the occurrence of problems and to obtain a stable driving situation.

[0063] Since the pyrolysis temperature in these pyrolysis chambers 30 is significantly lower than the combustion temperature at which dioxin or the like is generated, plastics containing chlorine in the waste, etc., as in the conventional magnetic field pyrolysis apparatus 1 However, even if dioxin is hardly generated, even if harmful gases are contained in the cracked gas, the cracked gas containing these harmful substances is provided in the vent hole 25. In the cracked gas treatment space 30 ′, which is the upper space of the partition plate 12 of the thermal decomposition treatment chamber 30 after being magnetized by the ring-shaped magnet 26, harmful substances in the cracked gas are further thermally decomposed, and the water treatment device Since the water is treated at 7 and exhausted from the exhaust stack 9, the exhaust from the magnetic field pyrolysis apparatus 1 can be made even cleaner.

[0064] Then, the pyrolyzed waste is reduced in volume to 1/200. It becomes magnetized ash, is taken out from the ash outlet 32, and is used as a heat insulating material for other magnetic field pyrolysis apparatus 1.

[0065] Here, when the ring-shaped magnet 50, which is a feature of the magnetic field pyrolysis apparatus 1 of the present embodiment, is inserted, and a pair of magnets having substantially the same magnetic force as those of the ring-shaped magnet 50, The following is a comparison of the processing time or the processing amount per unit time when the ring-shaped magnet 50 is disposed outside the external conduits 20a to 20p.

[0066] In these comparisons, the volume of waste thrown into the pyrolysis chamber 30 is a maximum of 1 cubic meter, and the amount of waste reduced by pyrolysis for a predetermined time is thrown in after the predetermined time. The results of comparison based on the amount of input (volume) are shown below.

1]

From the results of Table 1, when the ring-shaped magnet 50 is interpolated, waste of about 0.4 cubic meters can be stably injected every 5 hours. The waste power is 0.4 cubic meters every 5 hours, while a stable pyrolysis chamber is used, but instead of the ring magnet 50, a pair of plate magnets with almost the same magnetic force is used. When used, only 0.25 to 0.32 cubic meters of waste can be added every 5 hours, and the processing capacity is lower than that of the ring magnet 50. It can be seen that there is a large variation in the processing capacity, and that stable pyrolysis is not performed.

[0067] As shown from these results, according to the magnetic field pyrolysis apparatus 1 of the present example, the ring-shaped magnet 50 is internally placed in the external conduits 20a to 20p so that the external conduit 20a to The outside air that passes through p passes through the ring-shaped magnet 50 while being in contact with or very close to the ring-shaped magnet 50, and the inner diameter of the ring-shaped magnet 50 is made smaller than the inner diameter of the external pipes 20a to 20p. When outside air passes through the magnetite 50, it can generate turbulent flow in the outside air. Compared to the case where a pair of permanent magnets are arranged outside the road, even with an inexpensive permanent magnet with a low magnetic force, the outside air can be magnetized well, and thus the ability to obtain a stable thermal decomposition operating condition. S can.

[0068] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, when the ring-shaped magnet 50 having the N pole and the S pole in the thickness direction is used, a magnet as shown in FIG. 9 is used. In comparison, the magnetic flux density inside the ring-shaped magnet 50 can be improved, and the outside air passes through the ring having the high magnetic flux density, so that a large change in the magnetic field is applied to the outside air, resulting in a larger magnetic field vibration. Motion can be applied to the outside air, and the adjacent ring-shaped magnets 50 are inserted so that the opposing surfaces have different poles, so that magnetic flux also exists between these adjacent ring-shaped magnets 50. Even when outside air passes between the ring magnets, magnetization processing is performed, so that it is possible to apply large magnetic field vibrations by magnetization processing efficiently without filling the outside air. Get the driving status of Can.

[0069] Conventionally, as described above, the amount of outside air that flows in by using the individual valves disposed on each of the external pipes 20a to 20p, for example, excessive outside air flows. Therefore, it is necessary to make adjustments so that the waste in the pyrolysis chamber 30 does not ignite and the outside air necessary for pyrolysis flows in. These adjustments are very complicated and require skill. On the other hand, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, the pyrolysis chamber 30 through a plurality of external pipes 20a to 20p depending on the size of the openings of the outside air intake ports 16 and 19. It is possible to regulate that the total amount of outside air flowing into the tank exceeds the predetermined upper limit, so that it is possible to prevent ignition of waste due to excessive outside air flowing into the pyrolysis chamber. In the vicinity of the external air flow inlets 17a-p from which the external pipes 20a-p were derived Depending on the thermal decomposition situation, the outside air that has flowed into the chambers 15 and 18 (chamber portion) is distributed to the respective external pipes 20a to 20p and flows into the thermal decomposition treatment chamber 30. It is not necessary to individually adjust the amount of outside air flowing in from each external pipe using valves.

[0070] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, the size of the voids generated by the thermal decomposition or new input of waste between the waste input into the thermal decomposition treatment chamber 30 is described above. By lowering the partition plate 12, it is possible to reduce the gas, and the gas existing in the gap can be exhausted to the cracked gas treatment space 30 ′, which is the upper space of the partition plate 12, through the air holes 25. As a result, there is an adverse effect on the pyrolysis process due to the presence of excess outside air in these gaps, for example, the outside air (oxygen) present in the gaps caused by the introduction of new waste, and the This makes it possible to suppress the occurrence of ignition etc. from the pyrolyzed waste present in the plant, and a stable operating situation can be obtained.

[0071] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, the cracked gas passing through the vent hole 25 is magnetized by the ring-shaped magnet 26, so that harmful substances contained in the cracked gas are removed. Since it is thermally decomposed in the cracked gas treatment space 30 ′, which is the upper space of the pyrolysis chamber 30 divided by the partition plate 12, the concentration of harmful substances contained in the exhausted cracked gas is This can be further reduced.

[0072] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, after the waste is introduced into the vertical passage 42 (lateral passage 35) serving as the input chamber from the external input port 13, the external door 14 is closed. In this state, the internal input port 31 is opened so that the waste in the lateral passage 35 serving as the input chamber can be input into the thermal decomposition treatment chamber 30. Since it is possible to prevent a large amount of outside air from flowing into the thermal decomposition treatment chamber 30 from the internal charging port 31 when it is introduced into the inside 30, the large amount of outside air flowing in during the thermal decomposition treatment In addition to preventing the ignition of waste, new waste can be continuously input without significantly affecting the thermal decomposition status, so that stable operation status can be obtained over a long period of time. Can do.

[0073] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, by putting waste into the external charging port 13 provided at a height position below the heat-resistant container 2, the thrown waste Is transferred to the internal charging port 31 provided at the upper position of the heat-resistant container 2 and then injected, so that the work efficiency in the operation of charging these wastes can be improved.

[0074] Further, according to the magnetic field pyrolysis apparatus 1 of the present embodiment, by making the heat-resistant container 2 cylindrical, outside air can be supplied almost uniformly into the pyrolysis chamber 30, for example, a conventional square box Since the undecomposed waste can be prevented from locally remaining in the corners of the pyrolysis chamber as in the case of the thermal crack chamber, the efficiency of the pyrolysis process can be improved.
