The film-covered dust bag becomes an indispensable new material for dust and material filtration and collection as well as precision filtration. The advantages of the dust collection filter bag for higher dust collection efficiency and longer service life are:
1. High surface filtration efficiency. Usually the industrial filter material is deep filtration. It depends on establishing a dust layer on the surface of the filter material to achieve effective filtration. The establishment of effective filtration time is long (about 10% of the entire filtration range) , High resistance, low efficiency, incomplete interception, high filtration and back pressure, frequent cleaning, high energy consumption, long service life, and large equipment footprint. Dust cannot be penetrated by the use of film dust filter bags. The filter material is surface filtration. No matter if it is rough or fine dust, it will be deposited on the surface of the filter material, that is, it will be retained by the pore size of the membrane itself. No initial filtration period will start, and the effective filtration will begin. Nearly one hundred percent of the time will be filtered.
2. Low-pressure, high-flux continuous work. Once the filter material of the traditional deep filtration is put into use, the dust penetrates and a dust layer is established, and the air permeability rapidly decreases. During the filtration, dust accumulated in the interior causes blocking and increases. The resistance of the dust removal equipment. The membrane filter material with a fine pore size and its viscosity, so that the dust penetration rate is almost zero, put into use to provide the best filtration efficiency, when the deposited material deposited on the surface of the membrane filter material reaches A certain thickness, it will automatically fall off, easy to clear the ash, so that the filter pressure is always maintained at a very low level, the air flow is always maintained at a high level, continuous work.
3. Easy to clean ash. Any operation pressure loss of a filter material directly depends on the amount of dust remaining on the surface of the filter material after leaving the dust, the amount of dust under the filter, and the duration of cleaning (only a few seconds for the film filter). Can)), has a very superior cleaning characteristics, each dust can completely remove the dust layer, the filter will not cause internal clogging, will not change the porosity and mass density, can often be maintained at low pressure loss.
4. Long life span. Regardless of what kind of ash removal mechanism is used, all the filters can be used together. It is a kind of filter material that can completely exert the filter function of the design function of the dust collector. Therefore, the cost is low. The film filter is A strong and flexible fibrous structure, compounded with a strong base material, so it has sufficient mechanical strength, combined with excellent deashing, reduces the strength of dust removal, and can achieve low and stable pressure loss. Long-term use, extend the life of filter bags.
