A plurality of water spray holes are provided on the spray pipe 5. The spray pipe 5 is connected to a liquid supply device. When the liquid supply device is working, the liquid can be discharged through the water spray holes on the spray pipe 5, thereby spraying and removing dust, desulfurizing and removing dust from the smoke passing through the treatment box 1. A rotating ring 4 is rotatably connected inside the treatment box 1. The rotating ring 4 is provided with a cleaning ring 402 that is gap-matched with the spray pipe 5. A driving assembly 6 for driving the rotating ring 4 to reciprocate is provided on the outside of the treatment box 1. When in use, the driving assembly 6 is used to drive the rotating ring 4 to reciprocate. As the rotating ring 4 rotates, the cleaning ring 402 reciprocates on the outside of the spray pipe 5, thereby cleaning the water spray holes on the surface of the spray pipe 5 through the cleaning ring 402.

[0027] Furthermore, the air inlet channel 2 is arranged at an angle, and the lower end of the air inlet channel 2 is connected to the processing box 1, thereby avoiding the overflow of liquid from the air inlet channel 2.
