The invention provides a wet dust removal and purification
system, and belongs to the field of
environmental protection. The
system comprises a dust hood, an
impeller, a dust remover shell, guide vanes, a motor, a first-stage
dewatering plate, a second-stage
dewatering grid, a baffle plate, a third-stage
dewatering port, an air return cylinder, an air inlet cylinder, an air curtain, an air return hood, a dust hood, a water inlet
pipe, a dust remover air outlet, a
rotating disc and a closed hood. Dust in the closed hood is sucked into the air inlet cylinder through the negative pressure effect of the dust suction hood and then enters the
impeller, the water inlet
pipe is opened and beaten to the
rotating disc, the dust is combined with water for the first time, the dust which is not captured and the captured
sewage enter the next stage, and the dust is combined on the guide blades for the second time; air purified by the dust remover firstly enters the dust hood through the air return cylinder for secondary dust removal, and the purified air is discharged into the closed hood through the two sides of the air return hood to form the air curtain, so that
zero emission of dust is realized. The dirty air is purified through a wet dust removal method, air flow stably circulates in the closed hood, and the wet dust removal device has the advantages of being large in
suction force, high in dust removal efficiency and good in
dehydration effect.
