In the embodiment of the invention, air firstly enters the first dust remover 1 for wet dust removal, the air enters the second dust remover 2 for further wet dust removal after being purified by the first dust remover 1, good dust removal rate and dust removal rate can be ensured, and the air after dust removal is discharged after being sterilized and purified by the sterilizing equipment 3. In addition, for the first dust collector 1, after entering the inside of the housing 101 from the bottom air inlet 108, the air spirally rises from bottom to top along the spiral air duct 104 to remove dust. In the air spiral rising process, a plurality of spray headers of the first spray device 105 form water mist in the spiral air duct 104, and the water mist is combined with haze particles in the air and can be settled down or move towards the inner wall of the shell 101 under the action of centrifugal force; meanwhile, a water film is formed on the upper surface of the spiral blade 103 by the first spraying device 105, and the water film flows downwards along the spiral of the upper surface of the spiral blade 103, so that on one hand, haze particles in the air can be adsorbed by contacting with the water film, and meanwhile, settled haze particles enter the water film on the upper surface of the spiral blade and flow downwards to the bottom of the shell along with the water film. The water film is formed on the partial inner wall of the shell 101 of the spiral air duct 104 by the plurality of spray headers of the second spray device 106, the haze particles in the air or the water mist formed by the first spray device 105 and the particles formed by the combination of the haze particles enter the water film on the inner wall under the action of centrifugal force, meanwhile, the haze particles in the air can also be contacted with the water film on the inner wall and adsorbed, and the water film on the inner wall falls to the upper surface of the spiral blade and the water film on the upper surface of the spiral blade and converges to the bottom of the shell.
