The term reverse pulse or jet dust collector refers to the air cleaner's cleaning cycle. To clean the filter, a quick burst of compressed air is shot through the filter media in the opposite direction of the dusty air stream. During normal dust collection, dusty air flows through the filter, and a solid layer of dust forms on the filter surface. This dust build-up is called a dust cake or filter cake. A quick burst of air shot through the filter in the opposite direction knocks the dust cake off the filter, breaking it apart. The dust cake crumbles and falls into a collection bin or barrel. Some dust collectors must stop in order to clean, while other can pulse clean while running. Reverse pulse cleaning was first used in fabric bag filters.
The jet filter consists mainly of the filter casing with a built in separation chamber, a dust collecting storage, the filter envelopes with supporting cage and multiple jets in every envelope and compressed air header plus distributor tubes, diaphragm pilot valve and sequential timer. The filter casing is made in sheet steel construction and welded at joints.
Reverse-jet dust collectors can be operated continuously and cleaned without interruption of flow because the burst of compressed air is very small compared with the total volume of dusty air through the collector. Because of this continuous-cleaning feature, reverse-jet dust collectors are usually not compartmentalized.
The short cleaning cycle of reverse-jet collectors reduces recirculation and redeposit of dust. These collectors provide more complete cleaning and reconditioning of bags than shaker or reverse-air cleaning methods. Also, the continuous-cleaning feature allows them to operate at higher air-to-cloth ratios, so the space requirements are lower.
