Inspection Standard of Bag Filter

Feb. 07, 2020

The dust removal efficiency of the bag type dust collector is inseparable from its dust removal mechanism. When the dust-containing gas enters the ash hopper through the deflector through the air inlet duct of the dust collector, due to the collision of the deflector and the reduction of gas velocity, etc Role, coarse particles will fall into the ash hopper, and the remaining fine particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity of the filter fiber and fabric, the dust is blocked in the filter bag Inside, the purified gas escapes from the bag and is discharged through the exhaust pipe.


The inspection standard of the bag filter is the general principle of the operation management of the dust removal system. So what is it? The following is intercepted by the PPC Bag Type Dust Collector Manufacturer.

The main contents are as follows:

1. Regularly clean the dust removal system and the dust collection site. The floor in the clean room should be kept clean. Dust should be handled in time or shipped outside the factory, and it is not allowed to be arbitrarily stacked in the factory area. Regularly clean the dust on the dust removal pipe and equipment.

2. Maintenance system The dust removal system should have large, medium and small maintenance systems in order to detect problems in time to prevent major accidents and ensure that the system runs well.

3. Maintenance system The dust removal system should have equipment maintenance system. If problems are found, they should be dealt with in time. If the filter material is damaged, it should be replaced in time.

4. Carry out the principle of switching vehicles, that is, the process equipment must be turned on before the equipment is turned on, and the process equipment must be turned off before the equipment is turned off; the equipment of the dust removal system should also be turned on and off in the order of turning the vehicle on; After leaving normal operation, leave the site.

5. Regularly check the inspection holes, closed doors, flange connections, measuring holes, air ducts, dust collectors, etc. of the dust removal system to prevent air leakage and blockage.

6. Check the vulnerable parts. The vulnerable parts of the dust removal system should be checked frequently and replaced in a timely manner, and the fan belt should be checked regularly for looseness, whether the bearings are well lubricated, and whether the starting equipment is complete. It is strictly forbidden to perform adjustment, oiling and cleaning during operation in some occasions.

 Bag Type Dust Collector

Bag Type Dust Collector

Bag Type Dust Collector's dust removal efficiency is up to 99%, and the dust removal efficiency is very high. The bag dust collector has a higher classification efficiency for fine dust with a submicron particle size. Simple structure and easy maintenance operation. It is not sensitive to the characteristics of dust and is not affected by dust and resistance. The range of air volume to be processed is wide, which reduces the emission of air pollutants.

Precautions when using a bag filter:

1. The pulse solenoid valve should not be hung too tightly or too tightly. If it is too loose, it is easy to accumulate dust.

2. The old and new dust-removing cloth bags should not be mixed to avoid the different damage time affecting the normal operation of the equipment.

3. Replace the dust-removing cloth bag, blow it with compressed air first, and then check whether there are holes in the hole. If the dust bag is covered with dust, rinse it with water and leave it to dry after it is dry.

4. The bag should be strengthened to clear the dust frequently to eliminate the clogging of the bag; to increase the resistance, it can be shown by the reading of the differential pressure meter. The clogging of the dust bag is the main reason for the abrasion, perforation and shedding of the dust bag.

5. Aging of the dust bag. Mainly due to the following reasons, the cause must be checked, elimination measures should be taken and the dust bag should be replaced.

6. Damage to the dust bag. The shape of the dust bag and the installation method and mechanism of the dust bag determine the position where the dust bag is easy to be damaged, and the inspection and maintenance can be performed accordingly.


The above is the inspection standard of the bag dust collector introduced by the supplier of Electrostatic Precipitator.
