Automatic pulse bag filter

The pulse bag filter is supported by a cage containing a Venturi tube, and a purge nozzle is arranged at the top of the filter bag. When working under normal conditions, the air flow from outside into the filter bags, and the dust is blocked on the external surface of the bags. During backblow, the pulse controllers open the electromagnetic pulse valve instantaneously, and the compressed air in the air manifolds is ejected from the purge nozzle. When passing through the Venturi tube, several secondary air is drawn in from the surrounding area and injected into the filter bags to purge the dust. Dust cleaning is carried out sequentially in row and does not affect the work of normal air flow. It is an online dust cleaning.

 

The lower hopper is equipped with a level detector, which will start the dust discharge valve and the solenoid valve to discharge dust when it reaches the setting value. Filter air volume up to 100-30000m3/h, with filtration rating up to 5-40um.
