The lid 13 is supported at one end by a hinge 23 and is provided so as to be rotatable in the horizontal direction. A lever 25 is provided at the other end of the lid 13 so as to be pivotable in the vertical direction. By engaging the lever 25 with a hook 27 fixed at a corresponding position of the processing container 3, the lever 25 is locked in a closed position. Is done.

On the bottom surface side of the processing container 3, a partition member 31 is provided for supporting the combustible material that has been charged in a state of being separated from the bottom surface 29 and dropping ash generated after the processing onto the bottom surface 29.
Both side surfaces of the processing container 3 have a double structure including an outer wall 33 and an inner wall 35, and an air inflow space 37 taken in by the intake pipe 5 is formed between the outer wall 33 and the inner wall 35. . The inner wall 35 is supported by a support piece 39 fixed to the outer wall 33.

The chimney 15 includes an exhaust pipe 41 and a plurality of staying tanks 43A, 43B, and 43C that are provided at intervals in the vertical direction in communication with the exhaust pipe 41. The lower retention tanks 43A and 43B have a liquid reservoir 45 at the lower end and a plurality of baffle plates 47 that alternately extend substantially horizontally from both sides to prevent the upward flow of gas.
The gas generated in the processing container 3 comes into contact with the baffle plate 47, is cooled while changing the flow path, is partially liquefied, and accumulates in the liquid reservoir 45.
In the uppermost retention tank 43C, a punching metal 49 is disposed substantially horizontally above the liquid reservoir 45, and a metal mesh 51 is disposed substantially horizontally above the punching metal 49.
On the upper surface of the wire net 51, an activated carbon layer 53 is provided as a filtration layer for promoting detoxification of gas discharged from the chimney 15.
As will be described later, a discharge valve 55 for taking out a liquid having the characteristics of a wood vinegar is provided in the liquid reservoir 45 of each staying tank 43.
In FIG. 1, reference numeral 57 indicates a temperature indicator that displays the temperature in the processing container 3.

As shown in FIG. 2, a plurality (four in this case) of units each including the intake pipe 5, the magnetic field generation means 7, and the air valve 9 are arranged in the front-rear direction on both sides of the processing container 3.
The intake pipe 5 does not have a power source that forcibly sucks outside air, but merely has a pipe structure for taking in outside air. When combustion (flameless combustion) occurs in the processing container 3, air is naturally taken into the inside through the intake pipe 5. The air intake amount at this time is adjusted by the air valve 9.

The inner walls 35 on both sides are arranged in a U-shape along the outer wall 33, whereby the inflow space 37 is also formed so as to surround the inner periphery of the processing container 3. A ventilation pipe 59 as a ventilation part is provided on the inner wall 35 so as to protrude substantially horizontally. As indicated by an arrow, the air taken in from the intake pipe 5 enters the inflow space 37 and then the ventilation pipe 59. It flows to the processing space 61 of the processing container 3 through.
A plurality of ventilation pipes 59 are provided so as to surround the processing space 61.

The ash outlet 63 is provided in front of and behind the processing container 3 so that the ash accumulated on the bottom surface 29 of the processing container 3 can be taken out efficiently.
Two partition members 31 are arranged, and each partition member 31 includes a rectangular frame and a plurality of bars extending in the front-rear direction.
As shown in FIG. 3, the combustible material is charged from the charging port 65 in a state where the charging port lid 11 is pivoted upward and opened.
Each vent pipe 59 has a shape in which the lower surface side of the inner end portion thereof is cut obliquely (here, approximately 45 °), and the tip end is not blocked by the combustible material introduced from the introduction port 65. You can supply air.
A ventilation hole 67 as a ventilation portion is formed above the ventilation pipe 59 in the inner wall 35, and air enters the processing space 61 from the ventilation hole 67.
The height of the inner wall 35 is limited to a predetermined position, and the space between the inner wall 35 and the outer wall 33 is open at the top of the processing container 3.

As shown in FIG. 4, the magnetic field generating means 7 includes a cylindrical holder 69 made of a nonmagnetic material, and magnets 71 and 71 held in the holder 69 so as to face each other. A male threaded portion 73 is formed on one end side of the holder 69, and the male threaded portion 73 is connected to the intake pipe 5 by being screwed into a female threaded portion 75 formed on the intake pipe 5. The intake pipe 5 is also made of a nonmagnetic material.
The air passing through the holder 69 is magnetized by touching the magnetic lines of force of the magnet 71 and enters the processing space 61 of the processing container 3 through the intake pipe 5 in a magnetized state.
Although depending on the polarity of the magnets 71 and 71, the direction of the lines of magnetic force may be either the direction orthogonal to the air flow or the direction along the air flow.

Next, the processing operation by the combustible material processing apparatus 1 will be described.
First, after putting a combustible material into the processing container 3 from the charging port 65, the charging port lid 11 is closed and the lid 13 is opened to ignite the combustible material. This ignition may be performed by putting a fired newspaper or the like, or by an ignition means such as an electric heating rod or a burner provided in the processing container 3. In short, it is only necessary to cause combustion in a part of the combustible material in the processing container 3. The combustion by this ignition is combustion accompanied by a normal flame.
When ignition is confirmed, the lid 13 is closed. In the initial stage, the air valve 9 is fully opened, and the amount of air is adjusted as the temperature in the processing container 3 rises. If the air valve 9 is left fully open, normal combustion with a flame with sufficient oxygen supply is achieved, and incineration is performed according to the same principle as a conventional incinerator.
However, in the combustible material treatment apparatus 1 according to the present embodiment, the amount of air supplied is gradually limited so that combustion in a state close to flameless is maintained. Here, the “near flameless state” means a state with almost no flame unlike combustion with a large flame by sufficient oxygen supply.

The state model of the process in the combustible material processing apparatus 1 is shown in FIG.
In the processing container 3, the state is, in order from the top, the untreated area C1, which is hardly affected by the processing mechanism in the container, the dry area C2 where the moisture of the combustible material evaporates, and the volatile matter of the combustible material volatilizes. It is considered that the carbonization region C3, the ashing region C4 in which the combustibles from which moisture and volatile matter have been removed are oxidized and decomposed, and the ashing completion region C5 that becomes a complete ceramic powder are considered.
The component volatilized in the carbonization zone C3 adheres to the inner wall 35, and carbonization proceeds by the radiant heat in the container and shifts to the ashing zone C4.

After ignition, the air valve 9 is adjusted to adjust the air inflow amount, that is, the oxygen amount, so that it is possible to burn while maintaining a nearly flameless state and maintain this combustion state.
It has been confirmed by experiments of the present inventors that the maintenance of the combustion state, which should be referred to as “smoldering”, is realized for the first time by supplying magnetized air.
Although the principle is not clear, it has been found that even if the amount is adjusted while supplying non-magnetized air, the above-mentioned "combustion in a state close to no flame" is not maintained simply due to insufficient oxygen.
Magnetized air is supplied to or near the carbonization zone C3. Due to the restriction of the oxygen supply amount, the inside of the processing vessel 3 becomes a reducing atmosphere, the organic matter is mineralized, and harmful substances such as NOx, SOx, dioxin are rendered harmless.
Therefore, it is considered that combustion (oxidation reaction) in an extremely low oxygen state is possible in the processing vessel 3 by supplying magnetized air. In addition, the temperature in the processing container 3 is 100 degreeC-300 degreeC.

As described above, the supply of magnetized air is extremely important. However, as shown in FIG. 2, in the combustible material treatment apparatus 1 according to the present embodiment, the ventilation pipe surrounds the processing vessel 3. 59 and the plurality of vent holes 67 are provided, the supply of magnetized air is not biased, and “combustion in a state close to no flame” can be favorably maintained.
Separation of combustible materials before treatment is not necessary, and garbage or petroleum products may be mixed.
As the process progresses, ash accumulates on the bottom surface 29 of the processing container 3 and the volume of combustible material in the processing container 3 gradually decreases. You can throw it in.
Therefore, once ignition is performed and the process starts to proceed, the above-described “combustion in a state close to no flame” is continued without stopping unless the introduction of the combustible material is stopped. This continuation of combustion proceeds with no supply energy such as electric power.

As appropriate, the lid 13 is opened to remove the accumulated ash. Since ash (ceramic) as a solid residue accompanying incineration has been rendered harmless, it can also be reused as a deodorant or culture soil.
Moreover, since the liquid as the gas residue collected in the liquid storage part 45 of the retention tank 43 of the chimney 15 exhibits the same characteristics as the wood vinegar liquid, it can be reused as an antiseptic, a disinfecting liquid, or the like.

A second embodiment will be described with reference to FIGS. Note that the same parts as those of the first embodiment are denoted by the same reference numerals, and unless otherwise specified, the description of the configuration and functions already described is omitted, and only the main parts will be described.
As described above, the gas discharged from the chimney 15 is rendered harmless in a very good state, but the main object of the present embodiment is to further increase the harmlessness (cleaning).

As shown in FIG. 6, an exhaust pipe 81 is connected to the upper end portion of the chimney 15 so as to return from the upper end portion and extend substantially vertically downward. As shown in FIG. 7, the exhaust side end portion 81 a of the exhaust pipe 81 is connected to a filtration unit 83 fixed to the back surface of the processing container 3.
As shown in FIGS. 8 and 9, the filtration unit 83 has two filtration parts 85A and 85B that are spatially partitioned, and the exhaust-side end 81a of the exhaust pipe 81 is the bottom surface of the filtration part 85A. To communicate with the inside of the filter 85A.
Each of the filtration parts 85A and 85B can be opened and closed by an opening / closing cover 87 from the back side of the processing container 3, so that the filter body 89 can be installed inside and outside. In FIG. 9, the opening / closing cover 87 is omitted.

The inside of the filtration part 85A and the filtration part 85B are communicated with each other through a ventilation pipe 91. The ventilation pipe 91 has a ventilation path configuration that exits from the upper end side surface of the filtration part 85A, passes through the inside of the processing container 3, and again exits the processing container 3 and is connected to the lower end side surface of the filtration part 85B.
As shown in FIG. 9, a hole 93 is opened on the bottom surface of each of the filtration parts 85 </ b> A and 85 </ b> B, and a filter body 89 is installed on the hole 93. The filter body 89 has a configuration in which activated carbon 89c as a filter material is placed in a container 89b having a net-like bottom surface 89a.
As shown by the arrows in FIG. 8, the gas emitted from the upper end portion of the chimney 15 passes through the exhaust pipe 81 and enters the inside from the bottom surface of the filtration portion 85 </ b> A and contacts the activated carbon (activated carbon layer) 89 c of the filter body 89. From the ventilation pipe 91, it once goes to the outside, passes through the inside of the processing vessel 3, and enters the inside from the lower part of the filtration part 85B.
After that, after contacting the activated carbon (activated carbon layer) 89c of the filter body 89 in the filtration part 85B, it passes through the exhaust duct 93 connected to the upper surface of the filtration part 85B and is finally connected to the upper surface of the exhaust duct 93. It is exhausted from a chimney 95 extending vertically.

A windproof cap 97 is provided at the upper end portion (exhaust side end portion) of the chimney 95 from the viewpoint of preventing a backflow due to the entry of outside air during a strong wind or preventing rainwater from entering.
Since the ventilation pipe 91 passes through the inside of the processing vessel 3 as described above, the gas whose temperature has been lost due to contact with the activated carbon 89c through the filtration unit 85A is directed to the filtration unit 85B. Heated. By the temperature rise of this gas, the function of the exhaust upward flow discharged from the chimney 95 through the exhaust duct 93 is enhanced, and the obstruction by the windproof cap 97 does not become a problem.
Moreover, compared with the case where it enters into the filtration part 85B in the state where the gas temperature fell, there also exists an advantage that the detoxification reaction by the contact with the activated carbon 89c of the filter body 89 in the filtration part 85B is improved.

Although the above detoxification function can be equally obtained by providing the filtration unit 83 extending above the chimney 15, the filter body 89 is disposed in the vicinity of the processing vessel 3 (here, on the back side) as in the present embodiment. By providing, it is possible to suppress the bulkiness of the entire apparatus in the height direction, and there is an advantage that the filter body 89 can be easily replaced and maintained by the user.
That is, the position of the filtration unit 83 can be determined from the viewpoint of making the apparatus compact, easy workability, and effectively using the heat of the processing container 3.
In the present embodiment, the two filtering units 85A and 85B are provided. However, three or more other-stage filtering methods may be used.
In the present embodiment, since the gas coming out of the chimney 15 is rendered harmless by the filtration unit 83, the activated carbon layer 53 of the uppermost residence tank 43C is not necessarily required.

Since the activated carbon 89c of the filter body 89 is gradually contaminated by contact with the exhausted gas, the detoxifying function is deteriorated over time. Although replacement is necessary in the long term, the detoxification function can be recovered by periodically cleaning the activated carbon 89c.
In order to restore the function of the activated carbon 89c and to make it last longer, in this embodiment, a filtering material cleaning means 99 for cleaning the activated carbon (activated carbon layer) 89c is provided.
The filter medium cleaning means 99 includes a liquid supply pipe 101 connected to a cleaning liquid supply source (including a water source and a pump) (not shown), a nozzle 103 provided at the tip of the liquid supply pipe 101, and an on-off valve 105. is doing.
For example, as shown in FIG. 9, the liquid supply pipe 101 having one end side 101a connected to a water source enters the processing vessel 3 from the filtration unit 85B side, and extends meandering to increase the heating efficiency, and from the filtration unit 85A side. It branches out from the processing container 3, and one enters the inside from the upper surface of the filtration part 85A, and the other enters the inside from the upper surface of the filtration part 85B.

When the on-off valve 105 is opened, warm water or hot water is discharged from the nozzle 103, and the activated carbon (activated carbon layer) 89c of the filter body 89 located below the nozzle 103 can be shower-washed.
In the present embodiment, water is exemplified as the cleaning liquid, but a chemical liquid capable of increasing the cleaning power may be used.
A water outlet 101b is provided on the side opposite to the water source connection side of the liquid feeding pipe 101, and hot water heated by heat in the processing container 3 by an on-off valve (not shown) can be used for other purposes. ing. That is, there is an added value as a hot water supply device using the heat of the processing container 3.
The activated carbon (activated carbon layer) 89c may be washed with water at room temperature. However, the washing function can be improved by washing with warm water or hot water using the heat of the processing vessel 3 as in the present embodiment. In addition, there is no need to provide a new heating energy source for cleaning.

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, the method is such that the operator adjusts the amount of air taken into the processing container 3 by operating the air valve 9, but an electromagnetic valve is provided instead of the air valve 9, and the controller is based on information from the temperature detection means or the like. May be automatically adjusted.
Further, although the air is magnetized before flowing into the intake pipe 5, it may be magnetized in the inflow space 37. The magnetic field generating means 7 may be an electromagnet instead of a permanent magnet.
