The surface of the dust removal bag has high efficiency of unfinished filtration. Under normal circumstances, when the industrial filter material is used for deep filtration, the dust removal bag is to a certain extent mainly dependent on establishing a dust layer on the surface of the filter material to achieve effective filtration. The establishment of effective filtration for a long time, large resistance, low efficiency, incomplete interception, high filtration and back pressure, frequent cleaning, high energy consumption, long service life, and large equipment footprint.
When the dust bag is in use, its dust-covered filter bag filter material, the dust can not penetrate the filter material, in the operation of the surface filter, regardless of coarse, fine dust, all deposited on the surface of the filter material, that is, the film itself aperture The filtrated material is retained, there is no initial filtration period, the beginning is effective filtration, nearly 100% of the time in the filter.
The dust bag is low pressure, and the flux is continuous. Under normal circumstances, the traditional deep-filtered dust filter bag filter, once put into use, so that its dust penetrates, to a certain extent will establish a dust layer, the permeability will drop rapidly . During filtration, dust accumulates on the inside and causes obstruction, which increases the resistance of the dust removal equipment.
The dust filter bag dust filter bag filter material with a fine pore size and its viscosity, so that the dust penetration rate is close to zero, when put into use to provide the best filtration efficiency, when the media deposited on the surface of the film filter material is filtered to achieve a certain When it is thick, it will fall off automatically, and it is easy to remove dust, so that the filtration pressure is always kept at a very low level, and the air flow is always kept at a high level, and it can work continuously. The
The surface of the dust bag is easy to remove dust. To a certain extent, it is a kind of pressure loss of the filter material directly depends on the amount of dust remaining after the cleaning or is left on the surface of the filter material, the amount of dust under the dust, and the length of cleaning time. Excellent dust removal characteristics, each dust can completely remove the dust layer, the filter material will not cause blockage, will not change the porosity and mass density, can often be maintained at low pressure loss.
