Problems solved by technology

[0002] In the prior art, there are mainly the following problems in the filter and dust collector for dealing with dust-laden gas: the screen mesh problem, because the screen mesh is an important part to support the particle layer and make the air flow evenly flow through the particle layer, it is easy to cause blockage and material leakage Phenomenon, especially high temperature resistant materials with poor processing performance cannot be used, and high temperature resistant materials cannot be coated due to air permeability requirements, so their high temperature re

Example Embodiment

[0010] Specific embodiment: The double-layer filter dust collector of the present invention includes a casing 1, a filter layer 2 located in the casing 1, a dust-containing gas inlet 3, a purified gas outlet 4, a back blow gas inlet 5, and a back blow gas outlet 6. The upper filter material outlet port 7 and the lower filter material outlet port 8.

[0011] The filter layer 2 is composed of a double-layer filter material with light upper layer and heavy upper layer, coarse upper layer and fine lower layer. The upper layer filter material 9 is expanded perlite particles with a particle size of 2mm and a bulk density of 70kg / m3; the lower layer filter material 10 is sea sand. The diameter is 0.8mm and the bulk density is 1500kg / m3. When filtering, the dust-containing gas passes through the filter layer 2 from top to bottom, first passes through the upper filter material 9 of coarse particles to trap most of the dust in the gas, and then passes through the lower filter material 10 o...

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 [0001] The invention relates to a dust collector, in particular to a double-layer filter material dust collector. Background technique [0002] In the prior art, there are mainly the following problems in the filter and dust collector for dealing with dust-laden gas: the screen mesh problem, because the screen mesh is an important part to support the particle layer and make the air flow evenly flow through the particle layer, it is easy to cause blockage and material leakage Phenomenon, especially high temperature resistant materials with poor processing performance cannot be used, and high temperature resistant materials cannot be coated due to air permeability requirements, so their high temperature resistance is poor; dust removal problem, when the particle layer is filtered and accumulated to a certain extent, it needs to be cleaned Regularly discharge all the particles out of the filter to clean the dust, and then send them all back to the filter for rec...
