When the filtration wind speed of the pulse bag dust collector is low:
It can improve the dust removal efficiency, enhance the dust cleaning ability, extend the dust cleaning cycle, and thereby extend the service life of the filter bag. However, if the filtration wind speed is too low, the filtration area and volume of the dust collector need to be increased accordingly, which will lead to a corresponding increase in the equipment’s floor space and increased investment; when the filtration wind speed is too high, it can be reduced. Small filtration area and volume reduce floor space and investment.
When the filtration wind speed of the pulse bag dust collector is too high:
Choosing a high filtration wind speed will affect the dust removal efficiency, increase the difficulty of dust cleaning, increase the filtration resistance, reduce the service life of the filter bag, and bring about increased operation and maintenance costs. In fact, selecting wind speed is a more complicated task, which is closely related to the nature of dust, the initial concentration of dust-containing gas, the type of filter material, and the cleaning method.
The key to correctly selecting the filtration wind speed is to first understand the properties of dust and dust-containing gases; secondly, to correctly understand and understand the relationship between filtration wind speed and dust removal efficiency, filtration resistance, and dust cleaning performance.
The size of the filtration wind speed depends on the characteristics of the dust-containing gas, the type of fabric and the nature of the dust. It is generally selected based on the recommended data in the dust removal equipment sample and the user’s practical experience. The filtration wind speed of pulse bag dust collector is about 1.2~2m/s, and the filtration wind speed of glass fiber bag dust collector is about 0.5~0.8m/s.
