Wet dust removal and purification system

Abstract

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.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a wet dust removal and purification system. Background technique [0002] Air pollution in my country's industrial sites is widespread and the situation is severe. Dust seriously pollutes the workplace environment, threatens the physical and mental health of employees and the safe production of enterprises. Therefore, it is necessary to strengthen dust pollution control and accelerate the development of dust removal devices. In the existing wet dedusting device, the dust collected by the wet dedusting equipment often has poor dehydration effect, resulting in high humidity at the outlet, insufficient combination of dust and water, and serious waste of water resources. In order to reduce or eliminate the hazards of dust, it is urgent to design a wet dust removal and purification system with high suction, high dust removal efficiency and good dehydration effect.
