The upper part of the shell 1 is provided with a feed inlet 7, and the opening of the feed inlet is rectangular. The feed inlet 7 is connected with a feeding conveyor 21, and a sealing hanging curtain 22 is arranged at the feed inlet 7, so that packed waste paper can enter the vertical bale breaking machine 4, and dust cannot escape.

The shell 1 is provided with a dust removal connecting pipe 11 at the top of the feed inlet 7, and the packed waste paper is processed by a vertical bale breaker 24 to become sheet waste paper and generate a large amount of dust. Wherein a part of the dust floats to the top of the bale breaker 24 and is discharged through a dust removal connecting pipe 3 and a dust removal fan which are arranged at the top of the vertical bale breaker 24.

The bottom of the shell 1 is provided with a discharge hole 8, and the opening of the discharge hole is also rectangular. A part of the dust falls onto the discharging conveyor 29 along with the waste paper, and a certain gap is required to be kept between the discharging port 8 of the bale breaker 24 and the discharging conveyor 29, and a rubber baffle 210 is arranged at the position in order to ensure that the dust does not leak along the gap.

Dust removal fans are arranged at the dust removal connecting pipe 25 and the dust removal connecting pipe 27.

In order to avoid the danger of dust in the discharging process, the dust removal fan adopts an explosion-proof fan.

The dust discharged from the dust-removing connecting

pipes

23, 25 and 27 enters the dust remover 30 for centralized treatment.

The dust remover 30 comprises an air inlet pipe 31, a diffusion pipe 32 and a main dust removing pipe 33, wherein one end of the air inlet pipe 31 is connected with the dust removing connecting pipe, and the other end of the air inlet pipe 31 is connected with the diffusion pipe 32.

The diffuser pipe 32 and the main dust removal pipe 33 are both arranged vertically, and the main dust removal pipe 33 is held vertically by a support frame 313.

The diffuser pipe 32 extends into the main dust removal pipe 33 from a part of the upper end, a plurality of through holes 311 which are uniformly distributed are formed in the pipe wall of the diffuser pipe 32 extending into the main dust removal pipe 33, a conical cover 312 is fixed at the upper end of the diffuser pipe in a sealing mode, the diameter of the conical cover 312 is larger than that of the diffuser pipe 32 and smaller than that of the main dust removal pipe 33, and a gap is reserved between the conical cover 312 and the inner wall of the main dust removal pipe 33.

The partition plates 38 are sequentially arranged above the diffusion pipes 32 in the dust removal main pipe 33 from bottom to top, and a certain included angle is formed between each partition plate 38 and the horizontal plane, and the angle is preferably 20-30 degrees. And the inclination angles of the adjacent partition boards 38 are symmetrical to each other; the partition plate 38 divides the main dedusting pipe into a plurality of cavities; the distance between the adjacent partition boards 38 is gradually increased from bottom to top, so that the space of each cavity is also gradually increased.

A through hole 34 is formed in the middle of each partition plate 38, a nozzle 37 is arranged on the higher side of the through hole 34 in the middle of each partition plate 38, and water mist sprayed out of the nozzle 37 can cover the through hole 34; a water dripping hole 38 is further formed in the lower side of each partition plate 38, and the dripping spray water gradually falls along the water dripping holes 35 and is finally discharged through a water discharging hole 39 formed in the bottom of the main dust removing pipe.

The invention starts from the principle of wet dust removal, namely, dust particles mixed in the waste gas are adsorbed together as much as possible by water mist formed by spraying water, the dust particles are removed by water circulation, and the waste gas after dust removal is discharged. 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:

as shown in fig. 11, the exhaust gas mixed with dust enters the diffuser 32 through the inlet pipe 31, a plurality of through holes 311 are uniformly arranged on the pipe wall 310 of the diffuser 32, and the speed of the exhaust gas is greatly reduced when the exhaust gas enters the through holes 311. At the top of the diffuser 32 is a cone cap 312, and the exhaust gas must follow the gap between the cone cap 312 and the housing 33 to continue moving upward.

The exhaust gas then hits the partition 38, the partition 38 being at an angle to the horizontal, and the through-hole 34 being provided in the middle of the partition 38. A plurality of partitions 38 are provided in the housing 33, the interval therebetween is gradually increased from the bottom upward, and the inclination angles of the adjacent partitions 38 are symmetrical to each other. The partition 38 thus divides the housing 33 into a plurality of chambers, and the space of the chambers is gradually increased.

When the exhaust gas enters the interior of the chamber, the flow direction of the exhaust gas is deflected due to the inclination of the partition 38, and a part of the exhaust gas enters the next chamber along the through hole 34 of the next partition 38; a portion of the deflection occurs in a direction that is inclined to the bottom partition 38. After passing through the several chambers, the exhaust gases are finally discharged through an exhaust pipe 36 arranged at the top of the housing 33.

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 is about 30m/s at the air inlet 3, the flow speed is reduced to 14-20m/s after passing through the diffusion pipe 32, then after passing through the plurality of partition plates 38, the speed of the waste gas passing through the through holes 34 is only about 7-12m/s, and finally the speed of the waste gas discharged through the exhaust pipe 36 is only 7-10 m/s.

Meanwhile, in order to remove dust from the exhaust gas, a nozzle 37 is provided at a higher side of the through hole 34 in the middle of each partition 38, and the sprayed mist can cover the through hole 34, thereby further reducing the flow velocity of the exhaust gas. As shown in fig. 13, a water dripping hole 35 is further formed at a lower side of the partition 38, and the dripping shower water gradually falls down along the water dripping hole 35 and is finally discharged through the water discharge hole 39.

As shown in fig. 12, the main structure of the diffuser 32 is shown: the wall 310 of the diffuser 32 is partly outside the housing 33 and partly extends into the housing 33. The pipe wall extending into the shell 33 is provided with a plurality of through holes 311 uniformly arranged, and the diameter of the through holes 311 is not too small. At the top of the tube wall 310 is a conical cap 312.

When the exhaust gas enters the inside of the diffuser pipe 32 through the gas inlet 31, the flow itself is relatively smooth. When entering the inside of the housing 33, a large amount of gas enters the inside of the housing 33 through the through holes 311, and since the space of the housing 33 is much larger than the inner space of the pipe wall 310, the flow rate of the exhaust gas rapidly decreases. The exhaust gas discharged first forms a low-speed turbulent flow region 314 in the housing 33, and the flow rate of the exhaust gas discharged subsequently is further reduced by the low-speed turbulent flow region 314 and the cone cap 312.

The dust remover is based on a wet dust removal principle, the flow velocity of waste gas is gradually reduced (can reach 7-10 m/s) by optimizing the structure of the dust remover, and dust in the waste gas can be removed by spray water under the condition of small flow. Meanwhile, the noise pollution can be greatly reduced due to the lower exhaust speed.

The shell of the vertical bale breaker in the embodiment is completely sealed except for the feed inlet 7 and the discharge outlet 8; the feed inlet 7 and the discharge outlet 8 are regular rectangles, so that the adjustment and the sealing can be conveniently carried out according to the sizes of the feeding conveyor and the discharging conveyor; the topmost end of the bale breaking machine shell is provided with a dust removal connecting pipe which can be connected with a dust removal fan for dust removal operation.
