as shown in fig. 15, as an embodiment, the diverter 8 includes a diverter plate 81, and the top of the diverter plate 81 is fixedly connected to the lower edge of the second water leakage hole 5132 through two connecting plates 82; the washing liquid falling from the second water leakage hole 5132 can be divided into two parts by the dividing plate 81, so that the contact area of the washing agent and the waste gas is further increased;
the working principle of the embodiment is as follows:
when the exhaust gas is introduced from the air inlet pipe 21 to the bottom of the tower body 1, the exhaust gas is circularly lifted by the auxiliary circulating device 22; the washing liquid in the liquid storage part 112 is pumped into the vertical pipe 33 by the circulating pipe 32 through the water pump 31; the washing liquid in the vertical pipe 33 flows out from the through hole, enters the inside of the distributing groove, and then enters the inside of the water diversion pipe 5112; a plurality of spray heads 5113 are arranged on the water diversion pipe 5112 at intervals; a single water curtain is formed by the spraying of a plurality of spray heads 5113; meanwhile, since the spray head 5113 is inclined, when the spray rack 511 sprays liquid, the spray rack 511 rotates relative to the stand pipe 33 due to the reaction force of the spray; on the one hand, the waste gas rising from the lower part of the tower body 1 is enabled to be in more sufficient contact with the washing liquid due to the dynamic rotation of the spray frame 511, meanwhile, the blades can stir the waste gas in the rotation process, turbulence is formed, and the residence time of the waste gas in the tower body 1 is delayed; so that the waste gas is neutralized more quickly; the sleeve 5115 can be driven to rotate while the spray frame 511 rotates;
since the packing support plate 512 is meshed with the gear column 412 through the partial toothed ring 5125 at this time, the motor 411 does not rotate at this time and the packing support plate 512 is initially positioned at the lowest under the action of the packing gravity and itself, at this time, the second guide hole 5124 or the first guide hole 5123 on the packing support plate 512 is matched with the deflector 7 (the second guide hole 5124 can be adjusted to be matched with the deflector 7 initially); when the sleeve 5115 rotates, the chute 5117 (convex chute) on the sleeve 5115 drives the collar 5116 to move upwards until the collar moves to the top; when the packing support plate 512 moves to the top under the constraint of the chute 5117, the second guide hole 5124 is completely separated from the flow guiding device 7, and the gear column 412 is rotated by starting the motor 411 to drive the packing support plate 512 to rotate forty-five degrees; the raw materials are adjusted from the station of the second 5124 of the guide hole matched with the guide device 7 to the station of the first 5123 of the guide hole matched with the guide device 7; when the filler supporting plate 512 falls, the filler supporting plate is just matched with the top of the flow guiding device 7, so that the flow guiding device 7 is inserted into the first 5123 of the guide hole; when the filler supporting plate 512 falls to the lowest position, all the flow guiding devices 7 are inclined because the aperture axis of the first 5123 is inclined; meanwhile, when the flow guiding device 7 is inserted into the filler layer above the filler supporting plate 512, the filler can be stirred to continuously break the balance of the filler layer, so that the filler layer continuously changes the gap in the layer, and the filler can be conveniently and better changed in position, so that harmful substances in waste gas can be better adsorbed; when the packing support plate 512 rises to the top again, the motor 411 is controlled to rotate forty-five degrees again, so that the station of the second guide hole 5124 is positioned at the top of the flow guiding device 7; thus, when the filler supporting plate 512 falls down for the second time, the guiding device 7 is matched with the second guiding hole 5124, so that the inclination angle of the guiding device 7 is opposite to the previous station; the steps are repeated, so that the balance of the packing layer is continuously broken, and the waste gas is better treated; at the same time, the waste gas sprayed by the flow device 7 generates rotational flow when being inclined, so that the residence time of the gas in the tower body 1 is further improved;
embodiment two:
this embodiment is an improvement made on the basis of the first embodiment;
as shown in fig. 3, the second washing device 52 and the third washing device 53 are identical in shape and structure with the first washing device 51; wherein the spray heads 5113 on the first washing device 51 and the third washing device 53 have the same angle and inclination direction, and the spray heads 5113 on the second washing device 52 are opposite to the first washing device and the third washing device; when the washing liquid is sprayed from the spray head 5113, the reaction force makes the rotation directions of the spray frames 511 on the first washing device 51 and the third washing device 53 consistent, and the spray frames 511 on the second washing device 52 are opposite; thus, a plurality of rotational flows are further improved in the tower body 1, and the residence time and the treatment time of the waste gas in the tower body 1 are further improved;
meanwhile, through the diversion device 7 on the spraying plate II 513 of the second washing device 52 and the third washing device 53, when the filler supporting plate 512 descends under the action of gravity, the second guide hole 5124 or the first guide hole 5123 is matched with the diversion device 7, the diversion device 7 is inclined through the constraint of the second guide hole 5124 or the first guide hole 5123, when the diversion device 7 is inserted into the filler layer above the filler supporting plate 512, the filler can be stirred to continuously break the balance of the filler layer, and in this way, the filler layer continuously changes the gaps in the layer, so that the filler can be better changed in position, and harmful substances in waste gas can be better adsorbed;
