[0029] The photocatalytic module includes a backwash nozzle 15 fixed to the inner wall of the body 1 and a catalytic filter cartridge 16 rotatably connected to the inner wall of the body 1. The top of the backwash nozzle 15 is fixedly connected to the backwash ring cavity 10. A group of backwash holes distributed in a linear array are opened inside the backwash nozzle 15.

[0030] The inner wall of the catalytic filter cartridge 16 is uniformly distributed with nano-catalytic material;

[0031] By setting the nano-catalytic material and the catalytic filter cartridge 16, the gas entering the catalytic filter cartridge 16 is effectively catalytically purified;

[0032] The bottom end of the catalytic filter cartridge 16 is rotatably connected to an air induced draft pipe 17, the other end of which is connected to the air collecting tube 5, the bottom end of the air induced draft pipe 17 is connected to a sewage branch pipe 18, the other end of which is connected to a sewage valve 13;

[0034] By setting the spiral brush 20, the dirt adhering to the catalytic filter cartridge 16 can be quickly brushed away;

[0035] The oxygen distribution shaft tube 19 is fixedly provided with an oxygen distribution channel with an open top at the axial position, and the top of the oxygen distribution channel is rotatably connected to the oxygen supply ring cavity 9. The interior of the oxygen distribution shaft tube 19 is provided with a plurality of oxygen distribution holes 21 distributed in a circumferential array and connected to the oxygen distribution channel.

After the spiral flow control piece 8 and the spiral brush piece 20 rotate, the feeding direction of the spiral flow control piece 8 and the spiral brush piece 20 are both downward, and the gas to be catalyzed enters the transparent lamp tube 3 through the air inlet pipe 24 and the air vent 14 for UV catalysis. The gas after UV catalysis is diverted to each catalytic filter cartridge 16 for catalysis, and the catalyzed gas is discharged through the clean air exhaust pipe 2. When the catalytic filter cartridge 16 needs to be recoiled, purified and discharged, the ozone generator 11 stops working, the air inlet pipe 24 stops intake, the clean air exhaust pipe 2 is closed, the sewage valve 13 is opened, the back-cleaning nozzle 15 discharges high-pressure gas, and the catalytic filter cartridge 16 rotates at the set speed.
