Wet-type electrostatic precipitator for waste gas treatment and using method thereof

Abstract

The invention provides a wet-type electrostatic precipitator for waste gas treatment. The wet-type electrostatic precipitator comprises an acid-resistant and alkali-corrosion-resistant metal dischargeelectrode, a dust collection electrode, a high-voltage discharge circuit, a waste gas main pipe, a waste gas branch, a purified gas outlet and a dust collection cavity, wherein the waste gas branch is connected to the side wall of the waste gas main pipe through a control valve, and part of the metal discharge electrode is sleeved in the waste gas branch. According to the wet-type electrostatic precipitator, acidic and alkaline waste gas, water vapor and dust can be removed, and the discharge electrode is not prone to be oxidized or bonded with oil stain to lose the discharge function.

Description

technical field [0001] The invention belongs to waste gas treatment technology. Background technique [0002] Wet electrostatic precipitator is a high-voltage electrostatic precipitator used to treat wet gas. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. Ideal equipment for atmospheric dust pollution. The wet electrostatic precipitator is usually referred to as WESP. The basic principle of dust removal is the same as that of the dry electrostatic precipitator. It has to go through three stages of charging, collecting and cleaning. [0003] The wet electrostatic precipitator has a high-voltage discharger and a discharge electrode, and another dust collection electrode. The discharge electrode is generally a metal tip; the dust collection electrode can be a conductive material or a non-metallic material (a conductive water film is formed by water flow).

AI Technical Summary

Problems solved by technology

[0004] In the process of producing glyphosate in pesticide and chemical enterprises, a large amount of glyphosate mother liquor is produced, which contains inorganic ammonia, organic amine and chloride ions, and ammonia gas and hydrogen chloride will be generated after being processed by the phosphorus-containing mother liquor recycling device for phosphorus products And dust, the interception efficiency of the bag filter is very low, the flue gas cools down after being discharged from the chimney, and produces fine particles of ammonium chloride, which together with water vapor have a tailing phenomenon
