Method for improving migration velocity of smoke in electric precipitator and device

Abstract

The invention relates to a method for promoting the smoke dust migrating velocity of an electric precipitator, which pertains to the technical fields of gas discharge physic and environment engineering, etc. The method arranges a discharge electrode at the mid plate clearance between two adjacent collecting electrode plates, and the discharge electrode is close to the outlet end of the clearance; the migrating direction of smoke dust is the same as the flowing direction of fume; the side clearance interval of the two collecting electrode plates at the direction of facing the gas flow is about 30 percent of the width of collecting electrodes; the fume flowing speed passing the side faces of the two collecting electrode plates is 5m / s to 25m / s; the voltage of direct current applied to the discharge electrode is 20-56kV. The method promotes the ion transport rate and the ion concentration of the discharge clearance as well as increasing the charged coagulation rate of the smoke dust, thereby promoting the smoke dust migrating velocity of the electric precipitator and solving the problems of poor performance, large volume, large roller steel consumption and high operation cost, etc. caused by the low migrating velocity of the smoke dust in the electric precipitator.

Description

technical field [0001] The invention relates to a method and a device for increasing the driving speed of smoke and dust in an electric precipitator, and belongs to the technical fields of gas discharge physics and environmental engineering. Background technique [0002] Modern electric dust removal and air purification technology has high dust collection (removal) efficiency and high reliability. Its role in reducing environmental pollution caused by industrial smoke has attracted more and more attention. Large-scale electric dust collector (EP) has been successfully applied in the fields of electric power, building materials, steel, nonferrous metallurgy, chemical industry and gas purification. At present, the number of electrostatic precipitators accounts for 75% of the total domestic market, and China has become a major country in the production and application of electrostatic precipitators in the world. However, there are still scholars who believe that there are sti...
