Cyclone Baghouse

A 20,000 cubic feet per minute centrifugal blower attached to the baghouse draws air from the eliminator exit, through the primary cyclone, and finally into the baghouse. Switchgrass that passes through the primary cyclone enters the baghouse through a tangential air duct. Due to its height, the baghouse is located on the outside of the process building. The baghouse works similarly to the primary cyclone, separating the material by size. The larger particles drop to the bottom while the smaller particles are forced onto a series of polyester bag filters. The dust that is collected on the bag filters is removed using a pulsed air jet on the clean side of the bags. All collected and filtered material exits through a rotary airlock at the bottom of the baghouse.
