Bipolar corona discharge soot aggregation and electro dedust method and instrument

Abstract

The invention discloses a kind of bipolarity corona discharge, dust smoke congeals gathers, the electricity dust removal method, it belonges to the haze dust removal technology domain, the containes dust smoke first passes through the positive and negative corona discharge area in haze,Causes the dust particle in the haze carry the positive and negative electric charge then mutually congeals and gathers into a bigger pellet,then put it into the electric precipitator to carry on the electricity dust removal.The invention also discloses the installment for implementating above method,including a smoke channel, the smoke channel is fixed in the front part of the electric precipitator, assembles at least group of corona discharge electrode and at least a group of negative corona discharge electrode in the internal, the positive and negative discharge electrode is separately connected with the high-pressured power source out-port and the output low pressure end.In this invention method the dust smoke in haze passes through positive and negative electronics corona processing to carry the electric charge then congeals, again enters the electricity dust removal installment to carry on the dust removal, enhances the dust removal efficiency.the stated installment use the single high-pressured power source, the positive and negative corona discharge simultaneously product, electrically charged congeals carries on in the identical room, the cost is low, the electrically charged efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of flue gas dust removal, and in particular relates to a dust removal method in which dust is condensed by corona discharge and then purified by electric dust removal and equipment for implementing the method. Background technique [0002] The flue gas contains a large amount of micron and submicron dust or smoke. These fine dust particles can directly enter the human respiratory system and seriously affect human health. For this kind of micron and submicron dust or smoke, the purification efficiency of ordinary electrostatic precipitators is very low, and it is difficult to meet the national PM2.5 particulate emission standards. [0003] At present, in order to improve the ability to collect fine dust, condensation technology is mainly used to pretreat flue gas. Currently reported coagulation techniques include chemical coagulation and physical coagulation. Physical coagulation mainly uses an external ele...

AI Technical Summary

Problems solved by technology

Since the positive load electrical channel uses the grounded plate electrode to divide the flue gas into two parts, most of the discharge current flows directly into the grounded plate electrode, resulting in low efficiency and high energy consumption
