Abstract

The invention relates to an electrostatic spraying and dust-removing system. One end of a shell is an inlet of a dust-removing system while the other end of the shell is an outlet of the dust-removing system; an air flow distributor, an electrostatic spraying device, a filtering dust-collecting and washing device and a water separator are arranged in the shell orderly from the inlet to the outlet; at least one atomizing nozzle is connected to a water supply pipe in the electrostatic spraying device, a high pressure static ring is arranged in front of each atomizing nozzle; the high pressure static ring is connected with a high pressure static generator at the outer part of the system through a lead; a filler is arranged in the filtering dust-collecting and washing device, and the upper part of the filler is provided with a water pouring distributor; the water pouring distributor is connected with a system external water supply pipe through a water pipe; and the bottom part of the filler is provided with a water collecting disk, and the water collecting disk is provided with a water draining pipe. The system can satisfy the dust removing requirement of grains in different sizes in air, and has a relatively good effect to filter the powder dust with the grain diameter being more than 0.1 micro meters.

Description

Technical field [0001] The invention relates to an electrostatic spray dust removal system, and relates to the technical field of air dust removal and filtration purification. Background technique [0002] At present, air particle pollution in China has attracted more and more attention from people and the country. In addition to the dust removal requirements of large particles, PM10 and PM2.5 particles have been introduced into the air quality evaluation range in many places, and small particles are filtered. The requirements are also increasing. Epidemiological studies have shown that there is a significant positive correlation between population morbidity and mortality and atmospheric particulate matter (PM) concentration. This correlation shows that particulate matter that migrates from the outside into the room has a significant impact on health. The surface of atmospheric PM2.5 adsorbs a lot of toxic and harmful substances, which is very harmful to human health. Fine par...
