A little bit of theory. How does a bag filter work?

The principle of operation of bag filters is based on the precipitation of dust particles on the surface of the filter media.

In this case, the formed dust crust is an additional filtering layer. The dust layer on the surface of the filter fabric grows as the filter works.  Accordingly, the hydraulic resistance of the entire installation grows.

When the hydraulic resistance reaches a certain predetermined level (e.g. 1200 Pa), the filter bags must be cleaned of the dust which has accumulated on them. This cleaning process is called regeneration.

It is performed by pneumatic compressed air impact into the filter bag filter element.

Regeneration of filter bags is carried out with compressed air at a pressure of 4-7 bar. The requirements to the quality of compressed air are not worse than 2-3 class according to ISO 8573-1.

Regeneration mode is automatically controlled by a controller located in a separate cabinet.

Filter bags are suspended vertically on a mounting plate (sieve), which serves for separating chambers with incoming contaminated and cleaned air.

Each filter bag has an internal wire mesh (skeleton) to support it and prevent it from collapsing.

Aspirating air through the system of gas ducts enters the bag filter. The differential pressure differential sensor of the controller measures the pressure difference between the clean and dirty gas chambers of the filter. When the set differential pressure is reached, the regeneration cycle starts and continues until the bottom set point of the bag filter resistance is reached.

The start and stop values of the regeneration process are determined individually for each filter by representatives of the adjusting organization (supplier) during commissioning.

How is the compressed air pulse fed into the filter bag?

There are pulse (blow-off) valves for this.

The controller sends a signal to the solenoid valve at the right moment, allowing a pulse of compressed air to flow into the blow-off tube.

During the regeneration process, the dust is deposited in a hopper, from which it is removed by a screw conveyor or a sluice feeder.
