Electrostatic precipitator structure

Abstract

An electrostatic precipitator structure includes a dielectric plate arranged between two collecting electrode plates, which define an air flow channel. The dielectric plate divides the air flow channel into two sub-channels. A plurality of discharge wires are attached on in the upper and lower surfaces of the dielectric plate for generating corona discharge in the sub-channels. When a gas with particles passes through the sub-channels, the particles are charged by the ions produced by corona discharge and then migrate to the collecting electrode plates by electrostatic force. This electrostatic precipitator structure may avoid intensive particle contamination on the discharge wires, wherefore particle collection efficiency is enhanced. Further, due to the insulating dielectric plate immobilize the attached ions, the corona current and the ozone concentration is reduced, wherefore power efficiency is enhanced.

Description

technical field [0001] The invention relates to an electrostatic precipitator structure, in particular to an electrostatic precipitator structure in which the discharge wire is not easily polluted by particles and can improve dust collection efficiency. Background technique [0002] The general electrostatic dust collection device uses the principle of potential difference to generate corona discharge (Corona Discharge) at high voltage to ionize the air, and the particles in the gas to be treated are charged by colliding with air ions, and move to the grounded dust collection plate, so as to To achieve the purpose of gas purification to remove particles in the gas to be treated. [0003] A traditional electrostatic precipitator structure 10, such as figure 1 As shown, several discharge electrode lines 12 are directly placed between two collecting electrode plates 14, 14', so as to use the discharge electrode lines 12 to generate corona, so as to pass between the two collect...

AI Technical Summary

Problems solved by technology

However, in this electrostatic precipitator structure 10, since the discharge electrode wire 12 is completely and directly exposed to the gas to be treated, the particles are easy to accumulate on the discharge electrode wire 12, resulting in a decrease in the electric field intensity, resulting in a decrease in the collection efficiency of the particles. decrease over time

In addition, the polluted discharge electrode wire 12 needs to be cleaned regularly by knocking, but the discharge electrode wire 12 is not easy to clean up; The dust collector needs to be shut down to avoid electrical short circuit
