Description
Technical Field
The invention relates to the field of dust removal equipment, in particular to a self-dredging type continuous operation bag-type dust remover.
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.
Present bag collector generally has two kinds of modes when the deashing, one kind is artifical deashing, efficiency is slow, another kind adopts low-pressure pulse's mode to carry out the blowback deashing, high efficiency and effect are showing, but the characteristics that two kinds of deashing modes can't avoid needing to shut down, lead to the filterable discontinuity of dust removal, whole filtration efficiency is comparatively low, especially when filtering to the dust removal of big work load, the in-process probably needs the deashing of several times of shutting down in order to guarantee dust collection efficiency, and the impact force of low-pressure pulse exists the possibility of destroying sack surface primary filter material, and the efficiency of artifical deashing is more low.
