[0036] In the present invention, when in use, the exhaust gas is first allowed to flow from the air pipe 4 into the air washing chamber 2. When the exhaust gas flows into the section of the air pipe 4 in the air washing chamber 2, the heat will be absorbed by the water in the water storage barrel 1. Then, the exhaust gas will first contact the coarse screen plate 10, and the large particle pollutants will be intercepted by the coarse screen plate 10 and fall into the ash storage box 16 below. When the rocker 5 is used to adjust the air flow from the air pipe 4 to the air washing chamber 2, the rocker 5 is rotated, and the rocker 5 drives the annular rack 7 to rotate, and the annular rack 7 drives the movable adjustment plate 8 to rotate, so as to adjust the area of ​​the air inlet. In this process, the movable adjustment plate 8 will also drive the rotating shaft 11 to rotate, and the rotating shaft 11 drives the scraper 12 to rotate, so as to scrape off the residual large particle pollutants on the surface of the coarse screen plate 10 and make them fall into the ash storage box 16.

[0037] Subsequently, the exhaust gas flows into the interior of the scrubbing chamber 2. A nozzle is provided at the top of the scrubbing chamber 2, which sprays water mist. The water mist can make small particles of pollutants gather together and fall together with the water droplets condensed from the water mist, falling from the center of the enclosure 33 and into the liquid accumulation barrel 34 below. The gas cleaned in the scrubbing chamber 2 will flow out from the fine screen plate 48. At the same time, the driving shaft 18 will drive the wide belts 19 and 21 to rotate, and the wide belt 19 will drive the brush belt 20 to continuously scrape the fine screen plate 48. A mixture of small particles of pollutants and water will adhere to the brush belt 20, and the comb plate 22 will scrape off the mixture adhered to the brush belt 20, and finally fall below. On the other side of the fine screen plate 48, a roller 47 continuously rolls on the surface of the fine screen plate 48. A plurality of highly elastic round-headed rubber nails are fixedly installed on the surface of the roller 47. The diameter of these rubber nails is smaller than the diameter of the holes of the fine screen plate 48. During the rolling process, these rubber nails can push out the mixture stuck in the holes of the fine screen plate 48, and then the mixture is swept down by the brush belt 20.

[0038] The driving shaft 18 drives the first belt 35 and then drives the rocker arm 36. The rocker arm 36 drives the clamping bar 38 to swing through the fulcrum rod 37. The clamping bar 38 causes the connecting frame 39 to perform reciprocating lifting and lowering motion, thereby allowing the connecting frame 39 to drive the roller 47 to roll on the surface of the fine screen plate 48.

[0039] The secondary rotating shaft 21 is driven by the driving shaft 18, and drives the driven rotating shaft 41 through the second belt 40. The driven rotating shaft 41 transmits the torque to the active bevel gear 42, and the active bevel gear 42 drives the driven bevel gear 43 to rotate. The driven bevel gear 43 drives the third belt 64 to rotate the transmission gear, and then the transmitted gear drives the passive gear. The passive gear and the driven secondary rotating shaft 44 rotate the eccentric rod 45 together, so that the eccentric rod 45 drives the extension rod 46 and the horizontal sleeve 27 to rotate, and then the horizontal sleeve 27 drives the scraper 32 to scrape the enclosure 33. During the scraping process, the vertical sliding rod 26 and the vertical sleeve 25 can keep the horizontal sleeve 27 in a state and will not rotate with the extension rod 46. At the same time, the vertical sleeve 25 includes the vertical sliding rod 26, and slides on the horizontal sliding rod 23 through the slider 24, so that the vertical sliding rod 26 will not hinder its own movement while limiting the rotation of the horizontal sleeve 27.

[0040] Finally, the exhaust gas coming out of the scrubbing chamber 2 flows into the interior of the photo-oxidation catalytic box 3 through the air inlet 59, and is irradiated by multiple ultraviolet lamp posts 49 to produce an oxidation reaction, thereby decomposing organic pollutants. When it is necessary to adjust the inclination of the rotating plate 50 inside the photo-oxidation catalytic box 3, the hand wheel 63 is turned, and the hand wheel 63 drives the bevel gear 2 62 to rotate, and the bevel gear 2 62 drives the bevel gear 1 61 to rotate, and the bevel gear 1 61 drives the two clamping plates 57 to rotate. The two clamping plates 57 clamp the connecting plate 54 together to achieve lifting, and the eccentric rod 2 53 rotates with the lifting of the connecting plate 54, and then transmits the torque through the chain 52 to realize the rotation of all the rotating plates 50. By changing the flow area of ​​the cross-section of the photo-oxidation catalytic box 3, the flow path and residence time of the exhaust gas in the photo-oxidation catalytic box are adjusted, so that the ultraviolet lamp post 49 can better irradiate the exhaust gas, thereby enhancing the treatment effect, and finally the exhaust gas flows out from the air outlet 60.
