Suction and Surface Filtration

The process begins as dust-laden air is drawn into the collector’s housing via a powerful main fan. The airflow is directed through a series of high-precision filter bags. As the air passes through the fabric of pulse bag filter, dust particles are trapped on the outer surface of the bags, while the purified clean air enters the upper plenum and is discharged back into the atmosphere or the factory.

This initial separation stage is critical for maintaining the overall air velocity and preventing premature wear on downstream components.

Automatic Pulse-Jet Cleaning

To prevent the bags from clogging, the system monitors the pressure differential. Once it reaches a preset limit, a sequence of high-pressure compressed air pulses is released through a diaphragm valve. This instantaneous jet of air creates a shockwave that travels down the bag of pulse bag filter, causing it to flex and shake.

This action effectively dislodges the accumulated dust cake from the exterior surface. The precise timing ensures that cleaning only occurs when necessary, significantly extending the lifespan of the filter media.

Collection and Discharge

The dislodged dust falls by gravity into the tapered hopper located at the bottom of the pulse dust collector. From there, it can be continuously discharged through a rotary valve or collected for easy disposal. This cleaning cycle happens row-by-row while the system is still in operation, ensuring there is no downtime for your production line.

By automating the secondary collection process, the system minimizes manual intervention and maintains a consistent negative pressure environment across the entire industrial workshop.
