The bag filter in the coal washing plant adopts negative pressure operation and is used for dust collection in the coal mill system. It has achieved good results in several years of use. Generally, dust removal bags are used as accessories for bag filters in coal washing plants.
At the beginning of operation, the bag filter in the coal washing plant often encounters some unforeseen situations, such as abnormal temperature, pressure, moisture, etc., which will cause damage to the new equipment. The rapid change in gas temperature can cause deformation of the fan shaft, resulting in an unbalanced state and vibration during operation. Once the operation is stopped, the temperature drops sharply, and when restarted, vibration will occur again. Choose different types of fans based on the gas temperature. So the quality of the trial operation of the dust collector in the coal preparation plant directly affects whether it can be put into normal operation. If not handled properly, the dust collector may quickly lose its effectiveness. Therefore, the trial operation of the equipment should be careful and cautious.
Characteristics of bag filter in coal washing plant
1. Due to the pleated cylindrical shape of the filter material, the density of the filter material arrangement is high, resulting in a compact structure and small volume of the dust collector;
2. The height of the filter cartridge is small, easy to install, and the maintenance workload is small;
3. The filtering area of the same volume dust collector is relatively large, the filtering wind speed is small, and the resistance is not high;
4. The folding of filter media requires strict sealing at both ends and no air leakage, otherwise it will reduce the effectiveness.
