Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] An electrostatic spray dust removal system such as figure 1 As shown, it includes a housing 2, an air distributor 3, an electrostatic spray device 4, a filter dust collection and washing device 5 and a dehydrator 6. One end of the housing is set as the dust removal system inlet 1, and the end is set as the dust removal system outlet 7. Inside the housing Air distributor 3, electrostatic spray device 4, filter dust collection washing device 5 and dehydrator 6 are arranged in sequence; electrostatic spray device such as figure 1 , figure 2 As shown, at least one atomizing nozzle 18 is connected on the water supply pipe one 9, and the water supply of the atomizing nozzle is introduced from the outside of the system by the water supply pipe one 9. There is a high-voltage electrostatic ring 17 in front of each atomizing nozzle 18, and the high-vol...

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, in China, atmospheric particle pollution has increasingly attracted people's attention, and it has also attracted the attention of the country. While large particle size dust removal requirements are required, PM10 and PM2.5 size particles are introduced into the scope of air quality evaluation in many places, and small particle size filtration The requirements are also increasing day by day. Epidemiological studies have shown that population morbidity and mortality are significantly positively correlated with atmospheric particulate matter (PM) concentrations. This correlation suggests that migration of particulate matter from outdoors to indoors has a significant impact on health. Atmospheric PM2.5 adsorbs a large number of toxic and harmful substances on t...
