when the treatment device works, only the air valves on the air delivery ports 27 aligned with the air inlet pipe 6 are in a movable opening state, and the air valves on other air delivery ports 27 are in a closing state, namely, VOC waste gas can only enter the annular shell 21 from the air delivery ports 27 aligned with the air inlet pipe 6, so that the VOC waste gas can pass through a plurality of groups of activated carbon layer frames 22, and the activated carbon in the activated carbon layer frames 22 purifies the VOC waste gas for the first treatment;
after entering the annular shell 21 through the air inlet pipe 6 and the air delivery port 27, the VOC waste gas firstly hits the arc-shaped inner wall of the annular shell 21, so that the VOC waste gas is split into two air streams encircling the arc-shaped inner wall, passes along the inside of the annular shell 21 and moves to the rear side, and passes through the active carbon layer frames 22 which are arranged at intervals, and finally the VOC waste gas encircles the communication position of the air inlet II 34 and the air inlet I33 and enters the degradation cylinder 31;
since the first air inlet 33 on the degradation cylinder 31 is positioned at the rear side of the interior of the purification box 1, and the air inlet pipe 6 is positioned at the front side of the interior of the purification box 1, one group of the second air inlets 34 on the annular shell 21 are aligned with the first air inlet 33 during operation, and the other second air inlets 34 are temporarily not aligned with the first air inlet 33, so that VOC waste gas can only enter the degradation cylinder 31 from the second air inlet 34 corresponding to the first air inlet 33;
then, the VOC waste gas is degraded by contact with the biological filter bed 32 in the degradation cylinder 31 to produce harmless inorganic matters, and the second treatment is carried out; simultaneously, the circulating water pump 36 is started, the biological bacterial liquid in the biological bacterial liquid tank 37 is pumped into the annular pipe and sprayed out through the atomization spray head 352, VOC waste gas pollutants absorbed and filtered by the biological filter bed 32 are filtered, and as the sprayed biological bacterial liquid flows back into the biological bacterial liquid tank 37, a filter filler (not shown in the figure) is arranged in the biological bacterial liquid tank 37, the biological bacterial liquid flowing back into the biological bacterial liquid tank 37 is filtered and intercepted again, the biological bacterial liquid is absorbed, degraded and purified in the biological bacterial liquid tank, the third treatment is carried out, the filtered biological bacterial liquid is pumped into the annular pipe again by the circulating water pump 36, VOC waste gas pollutants filtered and absorbed by the biological filter bed 32 are washed, and the purified VOC waste gas is discharged through the exhaust pipe 5;
when the position of the activated carbon layer frame 22 needs to be switched, firstly stopping the air inlet pipe 6 to enter air, then starting the motor 41, driving the gear 42 to rotate, driving the gear ring 43 to rotate, driving the annular shell 21 to rotate, driving the activated carbon layer frame 22 to rotate, changing the position of the activated carbon layer frame 22, enabling the activated carbon layer frame 22 far away from the air inlet pipe 6 to rotate to one side of the air inlet pipe 6, simultaneously switching a group of air delivery ports 27 to be aligned with the air inlet pipe 6, and at the moment, switching the position of the activated carbon layer frame 22, so that each activated carbon layer frame 22 can be uniformly contacted with VOC waste gas, the situation that the activated carbon layer frame 22 close to one side of the air inlet pipe 6 is excessively utilized, and the activated carbon layer frame 22 far away from one side of the air inlet pipe 6 is low in utilization rate is prevented, and the purifying effect of the VOC waste gas is improved;
meanwhile, when the active carbon layer frames 22 are switched, the windward side positions of the active carbon layer frames 22 are changed, and the windward side directions of the active carbon layer frames 22 are interchanged, so that the active carbon in each active carbon layer frame 22 can be promoted to be fully utilized, and the purifying effect of VOC waste gas is further improved.
