By setting the screw rod 23, the two threaded plates 24 can be driven to approach or move away from each other. Rotating plates 25 are rotatably installed on the outer walls of one sides of the two threaded plates 24. U-shaped plates 26 are rotatably installed on the outer walls of one sides of the two rotating plates 25. One of the positioning plates 9 is fixedly installed on the outer wall of one side of each of the two U-shaped plates 26. By setting the positioning plate 9, the role of assisting installation can be achieved. A plurality of positioning rods 27 are fixedly installed on the outer wall of one side of one of the positioning plates 9. A driving mechanism for driving the screw rod 23 to rotate is provided on the long box 8.

[0033] During use, the rotation of the screw rod 23 will drive the two threaded plates 24 to move away from each other, and drive the two rotating plates 25 to rotate and drive the two U-shaped plates 26, the two positioning plates 9 and the plurality of positioning rods 27 to move outwards. The outward movement of the plurality of positioning rods 27 can thus release the fixed installation of the two adsorption layers 14 and the filter net 15, eliminating the need for manual disassembly, replacement and reinstallation, and improving work efficiency.

[0037] Specifically, please refer to Figures 1-2, on one side outer wall of the box body 1, a water tank 17 is fixedly installed. On the top outer wall of the water tank 17, a water pump 18 is fixedly installed. One end of the water suction port of the water pump 18 is fixedly connected to a water suction pipe 20, and one end of the water outlet port of the water pump 18 is fixedly connected to a water outlet pipe 19. By starting the water pump 18, the water at one end of the water suction port of the water pump 18 absorbs the water in the water tank 17 through the water suction pipe 20 and is transported into the shunt pipe 12 through the water outlet pipe 19, and the water is sprayed out through a plurality of atomizing nozzles 13 to achieve all-round dust reduction of the waste gas.

[0038] Specifically, please refer to Figure 2 , one end of the water outlet pipe 19 penetrates through one side outer wall of the shunt pipe 12 and is rotatably and sealingly installed in the shunt pipe 12 through a bearing. The water outlet pipe 19 is rotatably installed in the shunt pipe 12 through a bearing, so that the phenomenon of entanglement will not occur.

[0039] Specifically, please refer to Figures 3-4 , on one side outer wall of the box body 1, a long-shaped frame 29 is fixedly installed.

[0040] Working principle: When in use, the waste gas enters the box body 1 through the air inlet pipe 4, and then by controlling the start of the first motor 6, the output end of the first motor 6 will drive the turntable 11, the shunt pipe 12 and a plurality of atomizing nozzles 13 to rotate. At this time, by starting the water pump 18, the water at one end of the water suction port of the water pump 18 absorbs the water in the water tank 17 through the water suction pipe 20 and is transported into the shunt pipe 12 through the water outlet pipe 19, and the water is sprayed out through a plurality of atomizing nozzles 13 to achieve all-round dust reduction of the waste gas;

[0041] During the dust reduction process, the waste water will flow on the filter screen 15, and the filter screen 15 separates the water and impurities, so that the waste water can be recycled again, avoiding waste of water resources and also reducing the use cost. When it is necessary to clean the impurities adsorbed on the filter screen 15, first open the box door 2, and then control the start of the cylinder 30. The output end of the cylinder 30 will drive the cleaning plate 28 to move and clean the impurities adsorbed on the filter screen 15, which cannot be manually operated and cleaned, reducing the labor cost;

[0042] When it is necessary to disassemble and replace the filter net 15 and the two adsorption layers 14, by controlling the start of the second motor 22, the output end of the second motor 22 will drive the screw rod 23 to rotate. The rotation of the screw rod 23 will drive the two threaded plates 24 to move away from each other, and drive the two rotating plates 25 to rotate and drive the two U-shaped plates 26, the two positioning plates 9 and the multiple positioning rods 27 to move outwards. The outward movement of the multiple positioning rods 27 can thus release the fixed installation of the two adsorption layers 14 and the filter net 15, eliminating the need for manual disassembly, replacement and reinstallation, thereby improving work efficiency.
