Description

Bag-type dust collector special for boiler

Technical Field

The utility model relates to a sack cleaner technical field specifically is a special sack cleaner of boiler.

Background

The bag type dust collector is a dry type dust filtering device. 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. The bag type dust collector is a dry type dust filtering device. 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.

After the conventional bag-type dust collector is used for a period of time, the efficiency of a dust collection mechanism is reduced, so that the filtering effect of a filter bag is reduced, the dust collection efficiency is reduced, unnecessary loss is caused, and air pollution is caused. Therefore, we improve the technology and provide a special bag-type dust collector for boilers.
