Description

Combined bag-type dust collector

Technical Field

The utility model belongs to sack dust removal field especially relates to a modular sack cleaner.

Background

The bag-type dust collector is a dry dust filter. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity falls into the dust hopper due to the sedimentation of the gravity, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. After the filter material is used for a period of time, due to the effects of screening, collision, detention, diffusion, static electricity and the like, a layer of dust is accumulated on the surface of the filter bag, the layer of dust is called as a primary layer, in the later movement process, the primary layer becomes a main filter layer of the filter material, and the filter material with larger meshes can obtain higher filtering efficiency by virtue of the action of the primary layer. Along with the accumulation of dust on the surface of the filter material, the efficiency and the resistance of the dust remover are correspondingly increased, and when the pressure difference between two sides of the filter material is large, some fine dust particles attached to the filter material are extruded, so that the efficiency of the dust remover is reduced. In addition, the air volume of the dust removal system is significantly reduced due to the excessively high resistance of the dust remover. Therefore, the dust is removed in time after the resistance of the dust remover reaches a certain value. The initial layer cannot be damaged during ash removal, so that the efficiency is prevented from being reduced.

At present, most of bag-type dust cleaning devices adopt pulse dust removal, the gas purification mode of the pulse bag-type dust collector is an external filtration type, dust-containing gas enters each unit filtration chamber through a flow guide pipe, particle dust in the dust-containing gas directly falls into a dust hopper after natural sedimentation and separation, and other dust enters a middle box body filtration area along with air flow under the guidance of a flow guide system and is adsorbed on the outer surface of a filter bag. The filtered clean gas is discharged through the upper box body and the exhaust pipe through the filter bag.

The existing pulse blowing device is arranged singly, namely a plurality of nozzles are needed for a plurality of filter bags, a plurality of air supply pipes and a plurality of electromagnetic valves are matched with the pulse blowing device, so that the structure of the blowing device is complex, the cost is high, and the pulse dust collector always needs small pressure to carry out dust cleaning for protecting a primary filter layer, so that the effect that one long filter bag is subjected to pulse along with the distance from a venturi tube is worse, the dust cleaning operation can not be well carried out on the lower part of the long filter bag, the dust cleaning is incomplete, and the filtering effect is poor. Therefore, the invention of an ash cleaning blowing device which can simultaneously perform ash cleaning treatment on the lower part of a filter bag and has simple structure and low cost on the basis of a pulse dust collector is a problem to be solved by the technical personnel in the field.
