The working principle is as follows: when the device is used, waste gas enters the working chamber 11 through the waste gas inlet pipe 2, the waste gas is primarily cooled by water at the bottom of the working chamber 11, the primarily cooled waste gas flows upwards through the airflow channel surrounded by the first tapered fins 304 and the second tapered fins 305, the condensing sheet 307 reduces the temperature in the airflow channel of the working chamber in the waste gas flowing process, oil components in the waste gas are condensed into oil drops on the surfaces of the first tapered fins 304 and the second tapered fins 305, so that the oil-gas separation effect is achieved, then the master control box 8 controls the water pump 404 to work, the water pump 404 pumps organic solvent in the water storage tank 401 into the spray pipe 402 and sprays out the organic solvent from the spray head 403, small particle impurities and organic and inorganic gases in the waste gas are dissolved and filtered, then the sprayed and washed waste gas passes through the wire mesh demister 417 and the water absorption layer 408, and liquid drop molecules in the waste gas are fully dried, then the waste gas is conveyed into a deodorization box 7 by a communicating pipe 6 for deodorization treatment, so that the waste gas meets the emission requirement;
after the exhaust gas is purified, the master control box 8 controls the first motor 301 and the second motor 309 to start, wherein the first motor 301 drives the first pipe 302 to rotate, and further drives the first conical fin 304 to rotate synchronously, during the rotation of the first conical fin 304, the balls 316 in the cleaning liquid channel 313 are under the action of centrifugal force to squeeze the first compression spring 317, and further open the cleaning liquid channel 313, so that the organic solvent in the water storage tank 401 sequentially passes through the first pipe 302, the cleaning liquid channel 313 and the second through hole 314 to be discharged to the surfaces of the first conical fin 304 and the second conical fin 305, so as to dissolve the oil stains adhered to the surfaces, meanwhile, the second motor 309 drives the first rotating gear 311 to rotate through the first rotating shaft 310, the first rotating gear 311 rotates to drive the annular gear 308 to rotate synchronously, and further causes the scraper 312 to rotate reversely relative to the first conical fin 304, thereby scraping the oil stains on the surfaces of the first conical fin 304 and the second conical fin 305, the scraped organic solvent flows downwards along the inclined surface of the second conical fin 305 to the recovery cavity 14, and at the moment, the master control box 8 controls the micro pump 406 to start, so that the organic solvent in the recovery cavity 14 is pumped back to the water storage tank 401 for recycling;
when sponge absorbs water the inflation of absorbing water of layer 408, the inflation of also absorbing water simultaneously of inflation strip 411, and then the inflation strip that absorbs water 411 promotes slider 409 along the upward motion of sliding chamber 15, when slider 409 moves to sliding chamber 15 top, control switch 412 is triggered, make total control box 8 receive break-make signal, and then total control box 8 control electric telescopic handle 414 extension, electric telescopic handle 414 extension drives extrusion piece 413 on the one hand and extrudes sponge layer 408 that absorbs water, extrude inside organic solvent, on the other hand extrusion piece 413 drives slider 409 downstream through slide bar 410, and then extrude the organic solvent in the inflation strip 411 that absorbs water, thereby make slider 409 get back to initial position.
