Four major factors affecting the filtration efficiency of bag filters

1. Impact of dust layer
At the beginning of purifying dusty gases with filter media, there is no dust layer on the filter media, and the ability to capture dust is relatively low; When the dust layer is formed, it has a good trapping effect on the dust.
2. Impact of dust characteristics
The particle size of dust has a significant impact on the filtering power of bag filters. About 1 μ M dust particles, with a graded filtration power of up to 95%; About greater than 1 μ M dust particles can stably achieve a filtration power of over 99%. The more charge the dust particles carry, the higher their filtering power. By utilizing this feature, charge is applied before or at the inlet of the bag filter. Regarding 1.6 μ The capture power of dust particles above m can reach 99.95%.
3. The influence of filter material characteristics
In woven filter fabrics, the surface of short fiber fabrics has a lot of fuzz, which simply forms a stable primary dust, and its filtering power is higher than that of long fiber fabrics.
4. The impact of filtering wind speed
The appropriate filtering wind speed makes the dust form a dust layer on the surface of the filter bag, which is conducive to dust capture.
The function of a bag filter is closely related to the dust layer on the filter bag, the characteristics of the filter material, the characteristics of the dust, and the filtering wind speed.
