Solution to filter bag clogging

1、It is necessary to avoid improper booting methods and avoid booting when the resistance of the dust collector is too large. When the dust collector runs below the dew point, problems are prone to occur. If the air intake is unevenly distributed, it will easily cause local corrosion of the dust collector housing. If it is impossible to avoid low-temperature start-up, heat preservation devices should be used, such as steam heat preservation or electric heating heat preservation.

2、It is better to use coated filter material, coated filter material or pre-coating the surface of the filter bag. For the more viscous dust, it is good to reduce the filtering wind speed, or increase the pulse blowing pressure, or use the off-line pulse cleaning filter bag method. But a better way is to increase the filtering area, reduce the filtering wind speed, and prolong the service life of the filter bag.

3、If the dust removal time is too long, the initial powder layer on the surface of the filter bag will be cleaned together, which will cause the filter bag’s filtration accuracy to drop. When the cleaning time is too short and the dust on the surface of the filter bag has not been completely cleaned, the filtration can be started immediately. Dust will gradually accumulate on the surface of the filter bag, which will cause clogging of the filter bag. You can adjust the injection controller after several test runs.
