Special anti-explosion bag dust collector used in underground coal mine

Abstract

The invention provides a special anti-explosion bag dust collector used in an underground coal mine, belongs to the technical field of dust collectors and aims to solve the problem of a poor anti-explosion effect in the prior art. The special anti-explosion bag dust collector used in the underground coal mine comprises a rack, wherein a main tank body is fixed on the rack; a plurality of bag cagesare fixed in the main tank body; the bag cages are sleeved with filtering bags; an ash collection hopper is communicated below the main tank body; the main tank body is of an 'H'-shaped structure; the main tank body comprises a left working part and a right working part; a connecting part is arranged between the left working part and the right working part; the connecting part is a connecting tube; an air inlet is formed in the connecting tube; air release holes are formed in both the left working part and the right working part and are both formed opposite to each other; the air release holes are connected with an anti-explosion mechanism capable of reducing air pressure inside the main tank body; the anti-explosion mechanism comprises a fourway pipe which comprises a main pipe, a port I, a port II, a port III and a port IV; the port I is connected with the air release hole in the left working part; the port II is connected with the air release hole in the right working part. The special anti-explosion bag dust collector has the advantage of good anti-explosion effect.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and relates to a special explosion-proof bag dust collector for underground coal mines. Background technique [0002] An existing bag-type dust collector mainly consists of a housing, a filter bag, an ash hopper, and a back-blowing and dust-cleaning device. The two sides inside the housing are dust removal chambers, the upper part of which is provided with an upper flower plate, the upper end of the filter bag is arranged on the upper flower plate, and the upper part of the upper flower plate is a clean air chamber. The part between the dust removal chambers on both sides of the shell is divided into upper and lower chambers by a sloping plate in the middle. The lower part is an air inlet chamber, which is connected with the air inlet on the front surface of the housing, and the upper part is an air outlet chamber, which is connected with the air outlet on the rear end surface of the hou...

AI Technical Summary

Problems solved by technology

Over the years, the industry has adopted a variety of dust collectors for treatment and achieved good results. However, due to many reasons, there have been problems such as large equipment footprint, short filter bag life, high equipment resistance, and high emission concentration that affect dust removal efficiency. However, due to the unreasonable internal structure layout of some existing high-efficiency dust removal equipment, when the gas and dust enter the dust collector, the expansion of the air pressure can easily cause the equipment to explode.
