The inspection work on dust filter bags of the bag filter dust collector

The operation of the bag can be divided into trial operation and daily operation. 

The dust bag should be done for those inspections.

1. When the bag filter is in trial operation, it is necessary to inspect the single part of the system, and then perform adaptive operation, and perform some performance tests. In daily operation, necessary inspections should be carried out, especially for the dust collector bag. Check the performance. Pay attention to the impact of changes in the load on the host device on the performance of the precipitator.

2. During the trial operation of the new dust bag, special attention should be paid to check the following points: whether the air volume and the pressure and temperature of each test point are consistent with the design. Pay attention to whether the condensation in the bag room exists and whether the ash discharge system is unblocked. Blockage and corrosion occur, and the accumulation of ash can affect the production of the host.

Third, the adjustment of the cleaning cycle and the cleaning time of the bag filter, this work is an important factor for the dust-retaining performance and operation status. If the cleaning time is too long, the attached dust layer will be cleared off and become a dust bag. Reasons for leakage and damage. If the cleaning time is too short and the dust on the filter bag has not been cleared, the filtration operation will be resumed, and the resistance will be quickly restored and gradually increased, eventually affecting the use effect. The direction of rotation of the fan , speed, bearing vibration and temperature. The installation of the filter bag, whether there is a bag drop, loose mouth, wear and the like after use, can be judged by visual inspection of the chimney discharge after commissioning.
