The fixed ring two drives the hinge rod to rotate. When the hinge rod rotates, it contacts the limiting block two and generates vibration.

By setting a collection device, specifically, when the rotating shaft rotates, it will drive the fixed ring 3 to rotate. The fixed ring 3 will drive the scraper to slide in the inner wall of the second sliding groove. The scraper will scrape the impurity particles adsorbed on the inner wall of the filter plate onto the surface of the baffle. When the rotating shaft rotates, it will drive the fixed ring 2 to rotate. The fixed ring 2 will drive the hinge rod to rotate. When the hinge rod rotates, it will touch the limit block 2 and generate vibration. The vibration will shake the impurity particles that fall on the surface of the baffle into the collection box for collection.
[0021] The filter cartridge 1 23 and the filter cartridge 24 are arranged opposite to each other. The spray pipe 13 is located above the filter cartridge 24, and the end of the spray pipe 13 away from the water storage tank 12 is bifurcated.
[0022] The bottom of the brush plate 32 contacts the bottom of the inner wall of the filter cylinder 23. The number of brush plates 32 is set to several, and the several brush plates 32 are arranged in a circular array with the fixing ring 31 as the center.
[0023] The inner wall of the slide 34 contacts the surface of the slider 36, the surface of the protrusion 37 contacts the surface of the limiting block 35, and the surface of the contact block 39 contacts the surface of the brush plate 32.
[0024] The surface of the limiting block 41 is in contact with the surface of the hinge rod 45, the surface of the scraper 48 is in contact with the inner wall of the filter plate 27, and the inner wall of the chute 47 is in contact with the surface of the scraper 48.
[0025] The filter plate 27 is located above the baffle 26. The surface of the spray pipe 13 penetrates the surface of the spray tower 10 and extends into the interior of the spray tower 10. The surface of the rotating shaft 22 penetrates the bottom of the spray tower 10 and extends into the upper interior of the spray pipe 13.
[0026] One specific application of this embodiment is: When using the system, the operator first needs to introduce the industrial waste gas into the spray tower 10 through the inlet pipe 11. The waste gas will rise slowly. Then, the water storage tank 12 needs to be activated, and the water in the water storage tank 12 will be sprayed out through the spray pipe 13. The industrial waste gas will react with the sprayed water to remove harmful ions from the waste gas and also to agglomerate impurities in the waste gas into particles, which will then fall into the filter cartridge 23. Next, the motor 29 needs to be activated, which will drive the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 will drive the cleaning device 2 to move, and the rotating shaft 22 will drive the fixed ring 31 to rotate. The fixed ring 31 will drive the brush plate 32 to rotate, and the brush plate 32 will remove the waste gas. Impurities at the bottom of the inner wall of filter cartridge 23 are swept to the bottom of the inner wall of spray tower 10. Simultaneously, as brush plate 32 rotates, its surface contacts the surface of contact block 39, causing it to slide within the inner wall of chute 34. Meanwhile, spring 40 provides tension to slider 36. When slider 36 is pulled to its maximum distance, spring 40 quickly pulls it back. At the same time, the protrusion 37 on the surface of slider 36 impacts the surface of limit block 35, generating vibration. This vibration is transmitted to the bottom of the inner wall of filter cartridge 23, dislodging particles clogging it and preventing accumulation. During industrial processes... After the exhaust gas rises and passes through the baffle 26, it will also pass through the filter plate 27. The inner wall of the filter plate 27 will further adsorb the impurity particles in the exhaust gas. When the rotating shaft 22 rotates, it will also drive the collecting device 3 to move. When the rotating shaft 22 rotates, it will drive the fixed ring 46 to rotate. The fixed ring 46 will drive the scraper 48 to slide in the inner wall of the slide groove 47. The scraper 48 will scrape the impurity particles adsorbed on the inner wall of the filter plate 27 onto the surface of the baffle 26. When the rotating shaft 22 rotates, it will drive the fixed ring 42 to rotate. The fixed ring 42 will drive the hinge rod 45 to rotate. When the hinge rod 45 rotates, it will touch the limit block 41 and generate vibration. The action will shake off the impurity particles that fall on the surface of the baffle 26 and collect them in the collection box 25. Then, the industrial waste gas, after being filtered twice, enters the activated carbon adsorption box 18 through the connecting pipe 17. The activated carbon adsorption box 18 will further filter the toxic gases in the industrial waste gas and then enter the hot air blower 20 through the connecting pipe 29. The hot air blower 20 will heat the filtered gas into water and carbon dioxide and then discharge it through the exhaust pipe 21. The wastewater at the bottom of the inner wall of the spray tower 10 can enter the filter box 15 through the conduit 14 for filtration. After filtration, it enters the water storage tank 12 through the conduit 26 for recycling.
