Dust filter bag is an important accessory to assist the bag filter to work normally, so we need to maintain the dust bag from time to time, Jason dust specifically for how to improve the dust bag dust removal efficiency do a lot of summary, the following will do a detailed introduction :

When bag filter is used, the dust removal efficiency of the dust bag will directly affect the working performance of the equipment, and also affect the user's choice of bag filter. Therefore, manufacturers should do their best to improve the dust collection efficiency of dust bags.

Our company has summed up the work experience of all aspects: we can improve the working efficiency of dust filter bags from different aspects.

1, to strengthen the dust filter bag seal. The dust removal system is mainly composed of the equipment body and the dust collection system and other equipment, such as a star unloader, import and export valves, conveying equipment and pipelines, inspection doors, etc.; firstly, the inspection of the inspection holes and doors is strengthened, and the inspection door is best. Is a double door, the door is sealed around the use of heat-resistant silicone rubber; Second, we must strengthen the sealing of the transmission equipment maintenance, to prevent leakage. All joints of the shell must be continuously welded, and no leaks or holes can occur. Therefore, inspection of the dust collection system, spot inspection, etc. should be strengthened. Check the dust collector air duct, shell on the flower board, etc. Sealed type and integrity, it is found that the exposed seam department must repair welding in time.

2. Strengthen the management of dust and reduce the concentration of smoke dust. When the design is complete, there must be certain technical requirements for the inlet concentration, temperature and wind speed of the dust collector. When the production system is reformed, it is necessary to increase the customs and increase the dust-falling point. At this time, it is necessary to consider the dust collector's capabilities and possible consequences, and it is best to match each other.

3, reduce the damage of dust bag. Dust bag outlet is most likely to be damaged. When installing and repairing or replacing the bag, please pay attention to make the centerline of the blowout port coincide with the centerline of the bag, otherwise it will cause the outlet of the bag to be damaged.

When using the dust bag, the staff must remember the maintenance of the bag, this will not only affect the life of the bag, but also affect the dust removal effect of the bag.

 Correct use of dust filter bag method:

1, the dust bag aging. The reason is mainly due to the following reasons, the cause must be investigated, take elimination measures and replace the filter bag.

(1) Hardening and contraction due to abnormally high temperatures;

(2) due to contact with vapors of acids, bases, or organic solvents;

(3) Reaction with water

2, dust filter bag clogging. When the dust bag is clogged, the resistance increases, which can be manifested by the reading of the differential pressure meter. Dust bag clogging is the main cause of filter bag wear, punching, falling off and other phenomena.

Causes the dust bag to clog

(1) Temporarily strengthen the dust removal to eliminate the clogging of the dust bag;

(2) Part or all of the filter bag replacement;

(3) Adjust the installation and operating conditions.

3, filter cloth should not be hung too loose or too tight, too loose and easy to dust, too tight and easy to pull bad.

4. Replace the filter bag, blow it with compressed air first, and then check if there is any hole. After the hole is repaired, leave it to be replaced. If the dust bag is dusted, rinse it with water and leave it to dry after it has dried.

5, the new process of old filter bags should not be mixed, to avoid damage to the normal operation of different equipment.
