Dust bag dust capacity, also known as dust load refers to the amount of dust deposited on the filter material per unit area when reaching a given resistance value. The dust holding capacity of the dust bag affects the size of the filter resistance and the length of the cleaning cycle. In order to avoid frequent cleaning of the dust removal equipment and prolong the life of the filter bag, it is generally required that the dust removal capacity of the dust removal bag be larger. The dust holding capacity of the dust bag is related to the porosity and air permeability of the filter material, and the felt filter material has a larger dust holding capacity than the fabric filter material. Dust bag filter efficiency. The filtration efficiency of the filter media depends on the structure of the filter media on the one hand, and on the other hand, it also depends on the dust layer formed on the filter media. From the perspective of filter structure, the filter effect of short fibers is higher than that of long fibers. Felt filter is higher than fabric filter. From the formation of the dust layer, for the thin filter material, after the dust removal, the dust layer is destroyed and the efficiency is greatly reduced. However, the thick filter material and the dust can also retain part of the dust in the filter material to avoid excessive cleaning. In general, the highest efficiency can be achieved without the filter material breaking. Therefore, as long as the design parameters are properly selected, the dust removal effect of the bag filter should be no problem.
How to purchase a high quality dust bag
Purchasing good dust bags Specifically, in order to meet the production needs of enterprises, dust bag should meet the following requirements:
1, has a good permeability, bag filter function is used to remove dust, so the filter capacity of dust, must be large enough. At present, there are some dust bags with relatively poor quality on the market. Each time the ash cleaning function is turned on, it will “shrink” once. This is an unqualified product.
2, anti-temperature, strong corrosion resistance. It is believed that most companies know that if the dust bag can not have good resistance to temperature and corrosion resistance, it will be destroyed soon, and the dust removal performance will be lost, which will affect the normal use of the bag filter.
3, easy to remove dust. The quality of the cleaning ash and the quality of the dust bag itself also have a certain relationship. For example, both the long fiber and short fiber materials, short fiber material, although there is a very good dust filter, but to clean up the dust above, it becomes more difficult.
