Precautions for prolonging the life of dust filter bag

1) New technology and old cloth bags should not be mixed to avoid the difference in damage time from affecting the normal operation of the dust removal equipment.

2) The aging of the cloth bag is mainly caused by the following reasons. It is necessary to investigate the cause, take elimination measures and replace the dust filter bag, 1.hardening and shrinking due to abnormal high temperature, 2. reacting due to contact with acid, alkali or organic solvent vapor, 3. Reacts with moisture.

3) The filter cloth should not be hung too loosely or too tightly. Too loose and easy to accumulate dust, and too tight to damage the normal temperature filter bag.

4). Blow the replaced cloth bag with compressed air first, and then check whether there are any holes. After the holes are repaired, keep them for replacement. If the filter bags are stuck with dust, rinse them with water, dry them and save them for replacement.

5). The clogging of the dust filter bag will increase the resistance when the bag is blocked, which can be manifested by the increase in the reading of the differential pressure gauge. The clogging of the bag is the main cause of the phenomenon of wear, perforation and falling off of the bag, and the cause of the clogging of the dust removal bag. , Check and repair according to the following table, Fomex cloth bags generally take the following measures: 1.Temporarily strengthen the dust removal to eliminate the blockage of the filter bag, 2.Replace the filter bag partially or completely, 3.Adjust the installation and operating conditions.

In the dust removal process, when dust-containing gas particles pass through the dust collector, the dust particles will be trapped on the outer surface of the filter bag, while the clean gas enters the filter bag through the filter material. The dust removal cage is used to support the filter bag and prevent the filter bag from collapsing. At the same time, it also helps to remove and redistribute the dust cake.

1. Burning treatment.

High temperature resistant filter bag.

This kind of treatment is mainly to use a fire port to burn off the surface of the fast-moving cloth, and then use a high-temperature roller to iron the surface of the cloth, so that the surface of the cloth is smooth and easy to clean. This improves the filter material cleaning. The performance of ash also satisfies the collection of fine dust.

2. Antistatic treatment.

Some dust in the specified concentration state will easily burn when encountering sparks. Therefore, for the flammable or explosive dust, the needle felt filter material must be selected with antistatic treatment.
