Double-row filter bag embedded type electric bag compound dust catcher with electric field area at front stage

Abstract

The invention discloses a double-row filter bag embedded type electric bag compound dust catcher with an electric field area at the front stage, and relates to an industrial dust catcher. The dust catcher is provided with an inlet horn, a casing, a smoke duct, a filter bag, an ash cleaning system, an ash hopper, a discharge electrode, a dust absorbing polar plate, a rear discharge electrode and dust collecting pore plates; the front end and the rear end in the casing are provided with an electric field area at the front stage and an embedded electric bag dedusting area at the rear stage, an air inlet of the electric field area is connected with the inlet horn, and a flow guiding adjusting plate is arranged between an air inlet of the dedusting area and an air outlet of the electric field area; an air purification chamber is arranged at the upper part in the casing, and the air inlet of the air purification chamber is connected with an air outlet of the dedusting area; the air inlet ofthe smoke duct is connected with the air outlet of the air purification chamber, and a lifting valve device is arranged at the top of the smoke duct; the ash hopper is arranged at the bottom of the casing; a bypass valve device is arranged at the top of the electric field area of the front stage, the discharge electrode and the dust absorbing polar plate are arranged at the front end of the casing to form the electric field area of the front stage; the rear discharge electrode and the dust collecting pore plates are arranged at the rear end of the casing to form an electric field of the rear stage; the filter bag is arranged between the two dust collecting pore plates to form a filter area of the filter bag; and the electric field area of the rear stage and the filter bag area form the embedded electric bag dedusting area.

Description

technical field [0001] The invention relates to an industrial dust collector, in particular to a double-row filter bag embedded electric bag composite dust collector in the front-stage electrified field area. Background technique [0002] At present, particulate matter in the air has become one of the main air pollutants in our country. The particulate matter in the air seriously affects the visibility of the air and also has a serious impact on human health. PM 2.5 Refers to particles with a particle size of less than 2.5 microns, known as fine particulate matter, which is one of the main causes of human lung disease, PM 2.5 The particle size is small, the specific surface area is large, and the surface is easy to enrich heavy metal elements such as As, Se, Pb, Cr and organic pollutants such as PAHs, PCDD / Fs, VOCs, etc. These substances are mostly carcinogens and gene virus mutagenic substances. The generation of particulate matter in the air is mainly due to the direct or...

AI Technical Summary

Problems solved by technology

The electrostatic precipitator is greatly affected by the charging performance of the dust, and the specific resistance of the fine dust is large, so it is difficult to charge, and the uncharged dust is easy to be discharged directly with the air flow, and the emission concentration of the flue gas is difficult to meet the national pollutant discharge standard

The bag filter purifies the flue gas through the filter performance of the filter bag fiber. It is not affected by the characteristics of the dust itself and has the characteristics of high dust removal efficiency. The service life is not long, but also consumes a lot of power
