[0019] The cleaning mechanism 7 further includes a collection box 76 fixed to one side of the air inlet 4 .

[0020] It should be noted that: the organic waste gas is injected into the filter box 1 from the air inlet 4, and the waste gas can be initially filtered through the activated carbon net 5, and then the spray mechanism 6 is started to filter the waste gas again by spraying water, and then the conveying fan 3 and the heater 8 are started, and the filtered waste gas is conveyed to the treatment box 2 by the conveying fan 3, and the waste gas combustion can be catalyzed by the heater 8, and finally the exhaust valve 12 is opened to discharge the waste gas from the exhaust pipe 11. When the activated carbon net 5 needs to be cleaned, the motor 71 is started to drive the screw rod 72 to rotate, and when the screw rod 72 rotates, the connecting block 73 can drive the two brushes 74 to move, and when the brush 74 moves, it can drive another connecting block 73 and make it move through the positioning rod 75. Through the coordinated use of the other connecting block 73 and the positioning rod 75, the brush 74 can be stably moved, and the activated carbon net 5 can be cleaned by the movement of the two brushes 74.
