Causes of clogging of bag filter bags
1. Excessive water content is one of the main reasons for the clogging of the filter bag. The cause of water content is usually condensation at low temperatures, especially in high temperature processing.
2.Infiltration of air. Air infiltration often occurs in the flange of the dust collector, the inspection door or the movable device of the dust collector. If the bag filter is not tightly sealed, the outside air will enter the dust collector. When dealing with high-temperature flue gas, the air will generate a low temperature zone inside the dust collector after the air enters, which will cause condensation at low temperatures and the dust collector will be corroded. And it will cause the filter bag to paste or compact.
3.Poor ash cleaning conditions of the bag filter bag. It mainly includes the frequent cleaning of the bag filter, and the cleaning time is too long. The frequency of dust cleaning is too frequent, and the pressure of dust cleaning will easily loosen the fiber structure of the filter bag, which will cause the increase of fine dust in the flue gas and cause the filter bag to become clogged.
4.The main reason for the clogging of the bag filter bag is that the filter speed is too high, the dust is too fine, and the dust is sticky. The dust removal of the filter bag is not good, resulting in condensation and compaction. If the wind speed of the dust collector exceeds the design standard of the filter bag, it is very easy to cause the fine dust in the flue gas to enter the inside of the filter bag fiber, causing the resistance of the filter bag to block up.
