Filter Bag Specifications: Filter bag specifications (length L and diameter D) are related to the inlet velocity of the gas into the filter bag. When the dusty gas enters into each filter bag, if the population speed V1 is too fast, on the one hand, it will accelerate the secondary flying of dust removal and dust reduction. On the other hand, the abrasion of the filter bag will increase sharply due to the friction of dust, so generally V1 cannot Too big.
Number of filter bags: The number N of filter bags is the total filter area A divided by the surface area Ai(m) of a single bag. Pair of round bags: Ai= пD·L, N=A·Ai.
Dust catcher’s dust-removing efficiency: The dust-removing efficiency of the bag filter is related to the nature of the filter bag, the filtration speed, the dust concentration of the gas, and the continuous operation time. These factors are interrelated and interact with each other. Therefore, the selection Bag filter design parameters should be fully analyzed and comprehensively considered. of course. The parameters of dust removal fittings, such as fan air pressure and air volume, which are matched with the bag filter, will directly affect the dust removal effect and should be considered together during design and use. With the continuous deepening of research on the theory and technology of bag filter, such as design parameters, filtration mechanism, filter performance, equipment structure and cleaning methods, the further research of bag filter in the paper industry production and environmental protection Will play a greater role.
