Contaminated Air Entry: Shutter Dampers
In the Blizzard Bag Filter FS filter, entry of contaminated air takes place through the space underneath the bag with shutter dampers.
The main advantage of a shutter damper is that when the air enters the filter, it “collides” with the shutter and disperses evenly along the filter elements, reducing the level of wear, as well as providing an even level of wear over the filter elements.
Installing shutter dampers provides a basis to save space in the dust extracting installation. Having a shutter damper in the baghouse provides a way to operate dust containing medium-sized and large particles which end up in the hopper right away after colliding with the shutter grid.
This is the cheapest version option in the Blizzard Bag Filter FS compared to the other ways of arranging contaminated air entry via damper plates or a side entrance.
Pneumatic Cleaning System
Periodically filtered bags get covered with dirt, which increases the filter’s resistance. In order for the system to work in an uninterrupted fashion without any pressure differentials, the bags need to be cleaned. Cleaning is done in the following way:
