The general problems and precautions of the operation and maintenance of the dust filter bag can be divided into three aspects: excessive dust emission, higher than normal pressure of the filter, and short service life of the dust filter bag. There is a significant correlation between the three. The brief introduction is as follows: The basic cause of dust emission overruns caused by excessive dust emission The initial layer of the filter bag surface is not OK, the filter bag is broken, the filter bag is poorly assembled; the separate description is as follows: The operating pressure of the dust collector is too lower than the designed one. It is most likely that the initial powder layer on the surface of the filter bag is insufficient. The reason may be that the filter bag’s filtration speed is too high, the filter bag’s cleaning cycle is too short, and the pressure of compressed air is injected. If it is too high, the loadability of dust will decrease.

Studies have shown that: Too high filtration rate will increase the discharge rate of dust. Too high filtration rate will break the initial dust layer and cause excessive wear due to dust impact on the filter bag. If the number of times of cleaning the filter bag is too high at this time It is very easy to cause the fabric of the filter bag to loosen, which will cause the dust collector to discharge excessively.

When setting the pulse cleaning cycle of the dust collector, it is better to ensure that the dust collector operates under a stable pressure and the set pulse cleaning cycle time is better. The pulse cleaning time is to ensure that the initial dust does not fall. The set time The cleaning is better. If the initial dust layer is insufficient, the cleaning cycle can be extended to compensate. If the pressure difference control is used, the stability of the inlet and outlet pressure settings of the dust collector can be improved.
