The pulse-jet type fabric filter is the leader of the baghouse technologies. With no moving parts in the basic design and removal efficiencies of greater than 99%, a pulse-jet baghouse can be designed to meet the available footprint for the plant along with the most cost-effective and efficient design for the operation.
With the Dustex® Pulse-Jet Fabric Filter, dirty gases enter the baghouse modules through a side inlet of the baghouse and are evenly distributed throughout the filter media.
The pulse-jet cleaning cycle is controlled by a solid-state timer or PLC that controls the pulses of the compressed air. Compressed air stored in an air header is released by a solenoid actuated pulse valve and travels from the blow pipes that are mounted above each row of the filer bags into the bags creating a pressure wave. This pulsed air travels down the length of each filter bag in a row, causing a ripple effect, thereby loosening and releasing the dust cake into the hopper.
