Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the electrode plate of the existing industrial asphalt oil fume dedusting equipment is easily adhered by grease particles, so that regular cleaning is required; and because the cleaning liquid is used for cleaning, the collected oil fume particles will be mixed and polluted by the cleaning liquid. It cannot be added back to the asphalt for utilization, resulting in the discharge and disposal of secondary pollutants

Abstract

The invention discloses a self-cleaning coating material for an electrostatic dust removal electric plate, and a spraying method thereof, wherein the self-cleaning coating material comprises, by weight, 10-25 wt% of an acrylic emulsion, 15-45 wt% of an organic silicon hybrid emulsion, 10-20 wt% of silver powder, 5-15 wt% of graphite powder, 15-20 wt% of a cosolvent, 0.1-0.5 wt% of a defoamer, and0-4.5 wt% of water. According to the present invention, through the innovation and use of the materials, the pure flue dust particles are collected without material consumption or cleaning, wherein the flue dust particles are volatilized due to the influence of the temperature in the asphalt, and can be re-used for the production of asphalt products after collection so as to achieve the secondaryutilization of the environmental protection collection.

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...
