HMC standalone pulse dust collector

The HMC single machine pulse bag dust collector adopts the pulse blowing cleaning method, which has the advantages of good cleaning effect, high purification efficiency, large processing air volume, long filter bag life, low maintenance workload, and reliable operation.
Single machine pulse bag filter is a single unit dust removal equipment with automatic dust cleaning structure. This bag filter is widely used in industrial and mining enterprises such as cement, mineral powder, mining, metallurgy, building materials, machinery, chemical industry, and grain processing.

working principle
The working principle of a dust collector is as follows: the dust containing gas enters the filtering chamber through the ash hopper (or lower open flange), and the coarser particles directly fall into the ash hopper or ash bin. The dust containing gas is filtered by the filter bag, and the dust is trapped on the bag surface. The clean gas passes through the bag mouth to the clean air chamber and is discharged into the atmosphere by the fan. When the dust on the surface of the filter bag continues to increase, causing the equipment resistance to rise to the set value, the time relay (or micro differential pressure controller) outputs a signal, and the programmable controller starts to work. The pulse valves are opened one by one, allowing compressed air to blow and clean the filter bag through the nozzle, causing the filter bag to suddenly expand. Under the action of reverse airflow, the dust attached to the bag surface quickly separates from the filter bag and falls into the ash hopper (or ash bin), and the dust is discharged from the ash discharge valve. After all filter bags are blown clean, the dust collector resumes normal operation.
