Abstract
The invention relates to a dust remover, in particular to a double-layer filter material dust remover, which comprises a casing, a filter layer, a dust-containing gas inlet, a purified gas outlet, a back flowing gas inlet, a back flowing gas outlet, an upper layer filter material outlet and inlet and a lower layer filter material outlet and inlet, wherein the filter layer is positioned in the casing and consists of double-layer filter materials, the upper-layer filter materials are light and coarse, the lower-layer filter materials are heavy and fine, the upper-layer filter materials are expanded perlite particles with the particle size being 1 to 5mm and the volume weight being 65 to 75kg/m<3>, the lower-layer filter materials are marine sand with the particle size being 0.5 to 0.8mm and the volume weight being 1500kg/m<3>, the casing adopts heat-resistant steel, and the heat-resistant temperature can reach 900 DEG C. The dust remover has the beneficial effects that the dust remover realizes the high temperature resistance, the reliability is high, the durability is realized, and the maintenance and the management are simple.
Description
Technical field
The present invention relates to a kind of deduster, particularly a kind of double-layer filter material deduster.
Background technology
In the prior art; Mainly there is a following difficult problem in the filter collector of handling dusty gas: the screen cloth problem because screen cloth is to support stratum granulosum and make air-flow evenly flow through the vitals of stratum granulosum, makes it take place to stop up easily and leaks and expect phenomenon; Particularly can not adopt the exotic material of poor processability; Also, can not apply exotic material, thereby its heat-resisting quantity is poor because of gas permeability requirements; The deashing problem after the granular bed filter dust stratification arrives to a certain degree, needs deashing; Regularly with all particle discharge filter external ash cleanings, all send back in the filter again behind the deashing and recycle, use this method to be prone to take place phenomenons such as fragmentation, putty, wearing and tearing; When using reverse gas cleaning, need instrument to stir stratum granulosum during because of blowback, this mode is difficult to carry out; General deduster involves great expense, and maintenance management is complicated.
Summary of the invention
The object of the invention is exactly in order to solve deficiency of the prior art, and a kind of double-layer filter material deduster is provided, and this deduster is high temperature resistant, and reliability is high, and durable in use, maintenance management is simple.
In order to achieve the above object, technical scheme of the present invention is: a kind of double-layer filter material deduster is characterized in that: comprise housing, be positioned at the filter course of housing; The dusty gas import purifies the back gas vent, the blowback air import; The blowback air outlet, upper strata filtrate exit port, lower floor's filtrate exit port.
Above-mentioned filter course is made up of lightness sensation in the upper and heaviness in the lower, upper coarse and lower fine double-layer filter material.
Above-mentioned housing adopts heat resisting steel, can be anti-900 ℃.
Above-mentioned double-layer filter material, upper strata filtrate are expanded perlite granule, and particle diameter is 1～5mm, and unit weight is 65～75kg/m3; Lower floor's filtrate is extra large sand, and particle diameter is 0.5～0.8mm, and unit weight is 1500kg/m3.
Beneficial effect of the present invention: this deduster is high temperature resistant, and reliability is high, and durable in use, maintenance management is simple.
Description of drawings
Fig. 1 is a structural representation of the present invention
The specific embodiment
Specific embodiment: double-layer filter material deduster of the present invention, comprise housing 1, be positioned at the filter course 2 of housing 1, dusty gas import 3 purifies back gas vent 4, blowback air import 5, blowback air outlet 6, upper strata filtrate exit port 7, lower floor's filtrate exit port 8.
The replacing that upper strata filtrate exit port 7 is used for expanded perlite granule, the replacing that lower floor's filtrate exit port 8 is used for extra large sand.
This deduster is high temperature resistant, and housing adopts heat resisting steel, can be anti-900 ℃.Do not have moving component, durable in use, reliability is high, and maintenance management is simple, and expense is low.Be applicable to the flue gas ash removal of stoves such as chemical industry, metallurgy, material, burning, the energy.
