[0043] (1) When in use, the exhaust gas is introduced into the cleaning chamber 1 through the air inlet pipe 2, and further evenly dispersed inside the cleaning chamber 1 through the multiple air outlet holes 506 on the inner wall of the annular tube 505. Then, the driving component is controlled to pressurize the water inside the water tank 502 into the rotating tube 503 and drive the rotating tube 503 to rotate. The water is further sprayed out through the nozzle 504 for rotational spraying, thereby removing dust from the exhaust gas.

[0044] (2) When in use, the water inside the water tank 502 flows into the circular bin 605 through the water inlet pipe 607. When it is necessary to control the cleaning mechanism to perform rotational spraying, the motor 601 is activated. The motor 601 drives the screw 602 to rotate.

When the circular plate 606 moves to the right, the water flow pushes the sealing ball 609 to move to the left to block the left side of the receiving hole 611. At this time, the water on the right side of the circular plate 606 is squeezed into the water outlet pipe 608 and enters the rotating pipe 503 through the water outlet pipe 608 for spraying.

[0045] (3) When the motor 601 drives the threaded block 603 to move left and right, it also drives the toothed plate 612 to move left and right. The toothed plate 612 drives the gear 614 to rotate. The gear 614 drives the rotating rod 613 to rotate. The rotating rod 613 drives the rotating tube 503 to rotate and spray through the transmission wheel 615 and the belt 616.
