s1: pressurizing waste gas and discharging the waste gas into the tank body (1) through the air inlet pipe (11), increasing the internal pressure of the tank body (1), pouring water flow into the uppermost rotary atomizing sheet (321) through the water injection pipe (7), spraying water mist outwards through an atomizing port on the surface of the rotary atomizing sheet (321), and adsorbing particles in the waste gas discharged from the air inlet pipe (11) by utilizing the water mist;
s2: the water adsorbed with the particles is filtered by using activated carbon, coconut shell carbon and a film-coated polyester filter material filled in a plurality of filter discs (4) in the diversion chamber until the water drops into the lowest diversion chamber, and the water permeates a unidirectional osmosis film (13) in the diversion chamber to be collected;
s3: the exhaust gas after particles are adsorbed in each split flow chamber is extracted through the annular adsorption pipe (5) arranged in the lowest split flow chamber, flows through the filter pipe (61) in the extraction and discharge process, filters harmful substances in the exhaust gas through the filter pipe (61), and is discharged outwards through the output shaft of the air pump (62) after the smell is removed.
