Dust-electrical-charge bag dust collector

Abstract

The invention discloses a dust-electrical-charge bag dust collector. Single chambers of the dust collector are of rectangular, three-dimensional and inverted-conical structures, gas purifying chambers are located on dust gas chambers, filtering bags are located between the gas purifying chambers and the dust gas chambers, and gas injection pipes for recycling blowback dust removing of the filtering bags; bag and bag cage assemblies for filtering gas are arranged in the dust gas chambers, dust-falling partition plates are installed on the side walls of the lower portions of the dust gas chambers and located at the upper portions of insulating-plate pulse dust cleaning pipes, the insulating-plate pulse dust cleaning pipes are connected with insulating-plate heaters, and insulating plates are fixed at the portions, on the sides of gas inlets and gas outlets, inside bodies; the gas inlets and the gas outlets are formed in one sides of the dust gas chambers, and corona heat preservation boxes are arranged on the other sides of the dust gas chambers, wherein the dust gas chambers and the corona heat preservation boxes are integrated; corona areas are arranged at the lower ends in the dust gas chambers, and ash buckets are arranged below the corona areas. Dust-gas separating is carried out through the negative pressure effect of fluid and the filtering function of the filtering bags, and purified gas is attached to the outer surfaces of the filtering bags through electrical-charge dust; dust layers formed by the filtering bags have small airflow resistance, and dust is easy to clean.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a dust charging type bag dust collector. Background technique [0002] At present, the dust collectors used on site are divided into bag dust collectors and electric dust collectors. The bag filter is to filter the dusty gas through the filter bag, collect the dust, regenerate the filter bag, and discharge the clean gas, so as to realize the purification of the dusty gas and the separation and collection of the dust by the bag filter. [0003] The electrostatic precipitator uses the establishment of a DC electric field to charge the dust in the dust-containing gas, and utilizes the characteristics of charged dust of the same sex to repel and the opposite sex to attract the dust to absorb the dust on the two poles, and through the dust collecting pole and the corona pole The process of dust removal and dust collection achieves the separation of dust and gas and the purification of dusty g...

Problems solved by technology

[0005] The domestic electric bag dust collector basically belongs to two-stage dust removal, the front stage is electric dust removal, and the rear stage is bag dust removal. The two-stage dust removal will make the dust collected by the latter stage finer, because the dust collector also has charged dust airflow in the channel. Therefore, part of the charged dust will have the problem of power loss, which will make it easier to embed finer dust in the filter layer of the filter bag of the dust collector, which will further cause poor regeneration effect of the filter bag and filter bag relatively low lifespan
