[0077] In this embodiment, a liquid supply pipeline is provided inside the spray plate 3013, and liquid can be supplied to the spray head 2 by using the hose 3015 and the spray plate 3013. When there is no need to clean the spray head 2, the rotating frame 306 is aligned with the vertical projection of the notch 3014, and the movable plate 304 and the rotating frame 306 are moved above the spray head 2 to prevent the cleaning brush 308 from affecting the normal spraying of the spray head 2. When the spray head 2 needs to be scrubbed, the movable plate 304 and the rotating frame 306 are moved to the bottom of the spray head 2 and squeezed with the spray head 2, and the spray head 2 is scrubbed by moving and rotating the cleaning brush 308.

[0078] In one embodiment of the present invention, see Figure 3 The movable plate 304 is rotatably connected to a rotating rod 3016 , and one end of the rotating rod 3016 away from the movable plate 304 is rotatably connected to the top plate 301 .

[0089] In this embodiment, the flue gas to be purified is introduced into the air pipe 402 through the air inlet pipe 401, and the flue gas enters the interior of the cylinder 1 through the air hole 403. During the spraying process, the spray liquid accumulates at the bottom of the cylinder 1 and can be discharged from the liquid outlet pipe 405. The purified flue gas is discharged from the air outlet pipe 406.

[0090] In this embodiment, the height of the spray liquid should be lower than the height of the air hole 403 to prevent the spray liquid from entering the air pipe 402 .

Through the setting of the buffer hole 502, the flue gas can fully contact with the spray liquid, thereby improving the spraying effect of the spray liquid.

[0094] In actual use, the flue gas to be purified is introduced into the air pipe 402 through the air inlet pipe 401, and the flue gas enters the interior of the cylinder 1 through the air hole 403. The spray head 2 is started to spray the spray liquid in the spray plate 3013 to purify the flue gas.

[0095] When the shower head 2 needs to be cleaned, the first servo motor 305 is started to rotate the rotating frame 306. When the rotating frame 306 is moved to coincide with the vertical projection of the notch 3014, the first servo motor 305 is stopped and the hydraulic telescopic rod 302 is started to move the moving plate 304 downward, and the rotating frame 306 passes through the notch 3014 and reaches below the shower head 2.

The rotating frame 306 also drives the moving gear 3091 to move, and the moving gear 3091 is meshed with the inner gear disc 3092, thereby driving the first bevel gear 3093 to rotate. The first bevel gear 3093 also drives the second bevel gear 3094 to rotate, and the second bevel gear 3094 drives the cleaning brush 308 to rotate through the rotating shaft 307, so that the cleaning brush 308 rotates while moving, so as to clean the spray head 2.
