Finished Product Collection Bag dust collection

Bag dust collection is a common air pollution control technology used to remove solid particles from industrial waste gases. It uses a series of bag filters as filter media to release clean gas into the atmosphere by intercepting and capturing particulate matter.

The following is the basic principle and working process of bag dust removal:

Principle: Bag dust removal relies on the function of bag filters to separate particulate matter. Bag filters consist of a series of elongated fiber bags through which gas passes while particles are trapped on the surface of the bags.

Filtration process: After the exhaust gas enters the bag dust collector, it enters the bag chamber after pretreatment (such as cooling, condensation or pre-dust removal). The exhaust gas passes through the bag filter, and the particulate matter is trapped on the outer surface of the bag, and the purified gas enters the bag chamber through the pores of the bag.

Dust cleaning process: As time goes by, the trapped particles gradually accumulate on the surface of the bag, forming a dust film. In order to maintain the normal operation of the dust collector, dust cleaning operations are required. Cleaning can be carried out in different ways, including pulse cleaning and mechanical cleaning. Pulse cleaning usually sprays compressed air or pulse airflow into the bag to knock off the particles attached to the surface of the bag. Mechanical cleaning uses a mechanical device (such as a vibrator) to vibrate the bag to remove particles.

Particulate matter treatment: The cleaned particles are collected and usually treated and disposed of. Disposal may include recycling, incineration, landfill or other appropriate waste disposal methods.
