Dust removal and purification equipment and dust removal and purification process

The invention is applicable to the technical field of air purification. The invention provides dust removal and purification equipment and a dust removal and purification process. The dust removal andpurification device comprises a charging barrel with a feeding port formed in the bottom, an atomizer assembly arranged on the charging barrel, a filtering assembly and a controller; the atomizer assembly and the filtering assembly are arranged from bottom to top in the axial direction of the charging barrel, an induced draft fan is arranged at the top of the charging barrel, and the induced draft fan is electrically connected with the controller. The atomizer assembly is arranged, so that dust can be atomized; the atomizer assembly and the filtering assembly are arranged from bottom to top in the axial direction of the charging barrel, so the filtering assembly is mounted vertically in the charging barrel in a hanging manner; under the action of air suction negative pressure of the induced draft fan, dust-contai
