In recent years, with the rapid development of our country's economy, the demand of various domestic industries on paper products is increasing, and among them, recycled waste paper pulping is one of the important raw materials for paper product production. For the convenience of transportation, the waste paper is generally bundled and packed by a packing machine after being recycled, and the packed waste paper must be dispersed for the treatment of a pulper before being sent to a paper mill for pulping and pulping. The first bale breaking method is that the forklift is lifted and then the bale breaking machine is thrown, and then the drum bale breaking machine is developed according to the principle of a drum pulper.
The principle of the rotary drum bale breaker is that the packed waste paper is conveyed into a continuously rotating horizontal rotary drum, and the waste paper bags are continuously lifted and dropped and move towards a discharge port by utilizing structures such as a vertical cone, a spiral piece and the like welded on the inner wall of the rotary drum. In this process, the bundled waste paper bales are separated. The bale breaker has a simple structure, but occupies a relatively large space, and a vertical bale breaker is developed later, and waste paper bags are scattered by two paper scattering rollers rotating in the same direction.
Since the packed waste paper contains a large amount of dust, shredded paper, and the like, a large amount of dust is generated at the sites of the bale breaker and the discharge conveyor.

As shown in fig. 1 to 3, the present embodiment discloses a dust remover for a waste paper bale breaking system, which includes a dust removing connection pipe arranged in the waste paper bale breaking system, the dust removing connection pipe is connected to the dust remover, the dust remover includes an air inlet pipe 1, a diffusion pipe 2 and a main dust removing pipe 3, one end of the air inlet pipe 1 is connected to the dust removing connection pipe, and the other end of the air inlet pipe 1 is connected to the diffusion pipe 2.
The diffusion pipe 2 and the dust removal main pipe 3 are both vertically arranged, and the dust removal main pipe 3 is kept vertically arranged by a support frame 13.
The diffuser pipe 2 is stretched into to the dust removal and is responsible for 3 by upper end partly, and the diffuser pipe 2 is provided with the through-hole 11 that a plurality of was evenly arranged on stretching into the pipe wall of the dust removal and being responsible for 3 inside, and the upper end of diffuser pipe is sealed to be fixed with awl lid 12, and the diameter of awl lid 12 is greater than the diffuser pipe 2 and is less than the dust removal and is responsible for 3, makes and leaves the clearance between the inner wall of awl lid 12 and dust removal and be responsible for 3.
The partition plates 8 are sequentially arranged above the diffusion pipes 2 in the dust removal main pipe 3 from bottom to top, and a certain included angle is formed between each partition plate 8 and the horizontal plane, and the angle is preferably 20-30 degrees. And the inclination angles of the adjacent partition plates 8 are mutually symmetrical; the clapboard 8 divides the main dedusting pipe into a plurality of cavities; the distance between the adjacent partition plates 8 is gradually increased from bottom to top, so that the space of each cavity is also gradually increased.
A through hole 4 is formed in the middle of each partition plate 8, a nozzle 7 is arranged on the higher side of the through hole 4 in the middle of each partition plate 8, and water mist sprayed out of the nozzle 7 can cover the through hole 4; a water dripping hole 8 is further formed in the lower side of each partition plate 8, and the dripping spray water falls step by step along the water dripping holes 5 and is finally discharged through a water discharging hole 9 formed in the bottom of the dust removing main pipe.
The utility model discloses start from the wet dedusting principle, the water smoke that forms through the shower water promptly adsorbs the dust particle that is mingled with in with waste gas together, gets rid of it through hydrologic cycle to the exhaust-gas discharge after will removing dust. The reason why the conventional wet dust removing apparatus needs a large amount of spray water is that the velocity of the exhaust gas entering the dust remover is very high (about 30-60 m/s), and if the flow rate of the spray water is too small, the spray water is blown away by the exhaust gas, and the dust removal cannot be realized. Therefore, to reduce the amount of spray books, the flow rate of the exhaust gas must be reduced, so that less spray water can be used to achieve the same dust removal effect. The specific working process is as follows:
the waste gas that is mingled with the dust enters into the diffuser 2 through intake pipe 1, is provided with the through-hole 11 that a plurality of evenly arranged on the pipe wall 10 of diffuser 2, and when waste gas entered through-hole 11, speed greatly reduced. At the top of the diffuser pipe 2 is a cone cover 12, and the exhaust gas must follow the gap between the cone cover 12 and the housing 3 to continue moving upward.
The waste gas can collide with the partition plate 8, the partition plate 8 and the horizontal plane form a certain included angle, and the through hole 4 is arranged in the middle of the partition plate 8. A plurality of partition plates 8 are arranged in the shell 3, the distance between the partition plates is gradually increased from the bottom to the top, and the inclination angles of the adjacent partition plates 8 are mutually symmetrical. The partition plates 8 divide the housing 3 into a plurality of chambers, and the space of the chambers is gradually enlarged.
When the waste gas enters the cavity, the flow direction of the waste gas is deflected due to the inclination of the partition plate 8, and a part of the waste gas enters the next cavity along the through hole 4 of the next partition plate 8; a part of the deflection occurs in the direction in which the bottom partition 8 is inclined. After passing through the several chambers, the exhaust gases are finally discharged through an exhaust pipe 6 arranged at the top of the housing 3.
The space of the cavity is gradually increased, so that the flow speed of the waste gas is gradually reduced, and through calculation of fluid simulation software, when the flow speed at the air inlet 1 is about 30m/s, the flow speed is reduced to 14-20m/s after passing through the diffusion pipe 2, then after passing through the plurality of partition plates 8, the speed of the waste gas passing through the through holes 4 is only about 7-12m/s, and finally the speed of the waste gas discharged through the exhaust pipe 6 is only 7-10 m/s.
Meanwhile, in order to remove dust in the exhaust gas, a nozzle 7 is arranged at the higher side of the through hole 4 in the middle of each partition plate 8, and the sprayed water mist can cover the through hole 4, so that the flow speed of the exhaust gas is further reduced. As shown in fig. 3, a water dripping hole 5 is further formed at a lower side of the partition plate 8, and the dripping shower water gradually falls along the water dripping hole 5 and is finally discharged through the water discharge hole 9.
As shown in fig. 2, the main structure of the diffuser pipe 2 is shown: the pipe wall 10 of the diffuser pipe 2 is partly outside the housing 3 and partly extends into the housing 3. A plurality of through holes 11 which are uniformly distributed are arranged on the pipe wall extending into the shell 3, and the diameter of each through hole 11 is not small enough. At the top of the tube wall 10 is a conical cap 12.
When the exhaust gas enters the inside of the diffuser pipe 2 through the gas inlet 1, the flow itself is relatively smooth. When entering the inside of the housing 3, a large amount of gas enters the inside of the housing 3 through the through holes 11, and since the space of the housing 3 is much larger than the inner space of the tube wall 10, the flow rate of the exhaust gas rapidly decreases. The exhaust gas discharged first forms a low-speed turbulent flow region 14 in the housing 3, and the flow rate of the exhaust gas discharged subsequently is further reduced by the influence of the low-speed turbulent flow region 14 and the cone cover 12.
The utility model discloses based on wet-type dust removal principle, through the structure of optimizing the dust remover, make the velocity of flow of waste gas reduce gradually (can reach 7-10 m/s), the spray water also can detach the dust in the waste gas under the condition of low discharge. Meanwhile, the noise pollution can be greatly reduced due to the lower exhaust speed.
