Precautions for stopping the operation of bag filter

Before stopping the operation of the bag filter, in addition to thoroughly cleaning the dust, attention should also be paid to the following issues:

(1) Moisture condensation often occurs in the bag room, which is caused by the cooling of humid gas, especially the gas generated by combustion. Therefore, the dust removal bag manufacturer needs to exhaust the humid gas and completely replace it with dry air before the system cools down. That is to say, after the process equipment stops running, the exhaust fan of the bag filter should run for a period of time before stopping operation. Dust removal accessories

During the long-term shutdown period, it is necessary to pay full attention to the cleaning and rust prevention of the fan to prevent dust and rainwater from entering the bearings (pay attention to the moisture-proof of the motor). Before stopping operation, the accumulated ash in the ash hopper should be completely removed. The ash cleaning mechanism and driving part should be fully oiled.

During the shutdown period of the bag filter, regular short-term operation (idle operation) is necessary to ensure dust removal

Maintenance methods for the normal operation of the system.

The rapid change in gas temperature can cause deformation of the fan shaft, resulting in an unbalanced state and vibration during operation. Once stopped, the temperature drops sharply, and when restarted, vibration will occur again. Choose different types of fans based on gas temperature.

The quality of the trial operation of the dust removal equipment directly affects whether it can be put into normal operation. If not handled properly, the bag filter may quickly lose its effectiveness. Therefore, it is necessary to be careful and cautious in the trial operation of the dust removal equipment.
