Causes and solutions of filter bag obstruction

1.What is the bag of paste (filter bag obstruction)

‘Paste bag’ is the dust bag in long-term operation or out of service in the process, in the humidity or oily substances in contact with the filter media conditions, dust in the dust bag filter surface or the filter material inside the condensation, adhesion of the situation. The external manifestation of this situation is that the resistance of the filter bag increases, which can be found from the increase in the value of the differential pressure meter. Filter bag clogging will cause the effective filtration area of the filter bag is greatly reduced, the air permeability decreased, aggravating the load on the fan, resulting in increased energy consumption of the fan or even can not run.

2. Consequences of bag jamming

Filter bag clogging is the main cause of filter bag wear, perforation, shedding and other broken words, which may lead to serious downtime of the dust collector. A coal-fired power plant in northern China uses more than 6 metres of filter bags, in the process of using a large number of fine dust adsorbed on the surface of the filter bag, resulting in the dust collector operating resistance from 1500Pa to 2200Pa, resulting in a total shutdown, bringing great losses to the power plant.
