Electro-coagulation and enhancement type electric bag compound dust remover

Abstract

The invention discloses an electrocoagulation and enhanced electric bag composite dust collector, which comprises an electrocoagulation combiner and an electric bag composite dust collector; A bipolar charging area with positive and negative alternating electric fields is formed, and a mixed coagulation is set behind the charging area to enhance the coagulation effect of dust particles. The electric bag composite dust collector includes an electric field area and a filter bag area. The electric field area is equipped with a high-voltage discharge line, a dust collecting plate and a vibration device, and the filter bag area is equipped with a filter bag and a pulse jet cleaning device. The invention utilizes the coagulation effect of heteropolar charged dust in the alternating electric field to strengthen the dust removal efficiency and total dust removal efficiency in the electric field area of ​​the electric bag composite dust collector, reduce the growth rate of filter resistance of the filter bag, prolong the injection time and filter bag service life.

Description

technical field [0001] The invention relates to an electric bag composite dedusting equipment, in particular to an industrial kiln flue gas PM used in the field of environmental protection 2.5 An electrocoagulation and enhanced electric bag composite dust collector for efficient collection of fine particles. Background technique [0002] Coal accounts for about 70% of my country's energy structure, and 70% of the country's soot emissions, 90% of sulfur dioxide emissions, and 70% of carbon dioxide emissions all come from coal combustion. Thermal power generation is a major coal-burning household in my country, with a large amount of smoke and dust emitted annually, and more than 70% of the smoke and dust discharged after the dust collector is inhalable particulate matter, which is one of the most important sources of man-made release of inhalable particulate matter in the urban atmosphere. The improvement of the control level of smoke and dust pollution from coal-fired power...

AI Technical Summary

Problems solved by technology

Both electrostatic precipitators and electrostatic bag composite precipitators are high-efficiency precipitators, but the collection efficiency of electrostatic precipitators for fine particles is low, and the outlet emission concentration is generally greater than 20mg / Nm 3

At present, there are no relevant reports and materials on the combination of electrocoagulation technology and electric bag composite dust removal technology.
