The relationship between the dust holding capacity of the dust bag and the filtration efficiency

Information
The dust holding capacity of the dust bag is also called dust load, which refers to the amount of dust accumulated on the filter material per unit area when a given resistance value is reached. The dust holding capacity of the dust bag affects the resistance of the filter material and the length of the cleaning cycle. In order to avoid frequent dust removal of the dust removal equipment and prolong the life of the filter bag, it is generally required that the dust holding capacity of the dust removal cloth bag be larger. The dust holding capacity of the dust bag is related to the porosity and air permeability of the filter material. The felt filter material has a larger dust holding capacity than the fabric filter material. Dust bag filter efficiency. On the one hand, the filtration efficiency of the filter material is related to the structure of the filter material, and on the other hand, it also depends on the dust layer formed on the filter material. From the point of view of the filter material structure, the filtering effect of short fibers is higher than that of long fibers. Felt filter material is higher than fabric filter material. From the point of view of the formation of the dust layer, for the thin filter material, the dust layer is destroyed after dust removal, and the efficiency is greatly reduced, while for the thick filter material, some dust can be retained in the filter material after dust removal to avoid excessive dust removal. Generally speaking, the efficiency can be achieved when the filter material is not broken. Therefore, as long as the design parameters are selected properly, the dust removal effect of the bag filter should be no problem.
