step 6: the generator (33) can be driven to move to generate electricity in the movement of the first transmission die wheel (32), and the first transmission die wheel (32) can also drive the first transmission belt (31) to move, so that the synchronization of the movement of each group of first transmission die wheels (32) is achieved;

and 7: the linkage turntable (23) can be driven to rotate by the movement of the second transmission die wheel (29), and then the end hinge rod (24) is driven, so that the piston (25) of the linkage turntable reciprocates in the piston cylinder (26);

and 8: through the reciprocating motion of the piston (25) in the piston cylinder (26), when the piston (25) moves downwards, the interior of the piston cylinder (26) is in a negative pressure state, so that the second one-way valve (46) is opened, and the VOC waste gas adsorption liquid in the VOC waste gas adsorption liquid storage bin (9) enters the side partition plate (16) through the VOC waste gas adsorption liquid inlet pipe (20) and the second valve port (48);

and step 9: the VOC waste gas adsorption liquid in the compression side partition plate (16) is opened when the piston (25) moves upwards, so that the VOC waste gas adsorption liquid is sprayed on the first active carbon filtering fan blade (22) and the second active carbon filtering fan blade (21) through the first valve port (17), the VOC waste gas adsorption liquid outlet pipe (27), the top hollow spraying plate (4) and the spraying head (34), and the VOC waste gas is transferred to the liquid phase;

step 10: the gas passing through the VOC waste gas inlet pipe (7) enters the through notch (15) in the VOC waste gas ozone decomposition pipe (10) again;

step 11: by starting the ultraviolet light net pipe (13), then connecting the air introduction connecting pipe (38) with the air pump, intermittently providing air, introducing the air into the air guide pipe (14) through the air introduction connecting pipe (38), then introducing the air into the air introduction auxiliary cleaning pipe (36) through the air guide pipe (14) to be sprayed around the ultraviolet light net pipe (13), and converting oxygen in the air into ozone through the ultraviolet light net pipe (13);

step 12: the gas passing through the VOC waste gas inlet pipe (7) is decomposed with ozone generated near the ultraviolet light net pipe (13) so as to carry out secondary filtration;

step 13: then, decomposing the VOC waste gas again through titanium dioxide on the back of the ultraviolet light net pipe (13) for the third filtration;

step 14: the gas after the three times of filtration is discharged through a gas discharge pipe (11);

step 15: when the ultraviolet light net pipe (13) needs to be cleaned, the driving motor (37) can be started to drive the driving bevel gear (39), the driving bevel gear (39) drives the driven bevel gear (42) to further drive the air guide pipe (14) to rotate, and the air guide pipe (14) drives air to be guided into the auxiliary cleaning pipe (36) to clean the ultraviolet light net pipe (13).
