A kind of self-cleaning coating and spraying method thereof for electrostatic precipitating electric board

Abstract

The invention discloses a self-cleaning paint for an electrostatic precipitator and a spraying method thereof. Based on the total weight of the self-cleaning coating for electrostatic precipitating panels, the self-cleaning coating for electrostatic precipitating panels includes the following components: 10-25wt% acrylic emulsion, 15-45wt% silicone hybrid emulsion, 10-20wt% silver powder , graphite powder 5-15wt%, co-solvent 15-20wt%, defoamer 0.1-0.5wt%, water 0-4.5wt%. Through the innovation and use of materials, the present invention realizes the collection of pure soot particles without consumables or cleaning. Because the soot particles themselves belong to the substances volatilized in asphalt affected by temperature, they can be used again to produce asphalt products after collection, realizing environmental protection collection secondary use.

Description

technical field

[0001] The invention belongs to the field of supporting materials for oil fume and dust removal equipment in the asphalt industry, and more specifically relates to a self-cleaning coating for electrostatic dust removal electric panels and a spraying method thereof. Background technique

[0002] In the tail gas collected by the asphalt industry, there are a large number of low and medium molecular weight organic viscous particles. Generally, after the asphalt tail gas dust removal equipment adopts electrostatic dust removal, its electrode plate will be covered by the oily particles in the tail gas, and it needs to be used every 1-2 days. The cleaning liquid is used for cleaning, so that the recovered tail gas solids cannot be directly used in production due to the mixing of the cleaning liquid, and new waste liquids are discharged, and there is a problem of secondary sewage discharge. The current dust removal and environmental protection equipment is all in th...
