The bag filter/ baghouse dust collectors work on the basic principle wherein the dust-laden gases enter the baghouse and pass through fabric bags that act as filters. The bags can be of woven or felted cotton, synthetic, or glass-fiber material in either a tube or envelope shape. Pulse Jet Bag Filters are used for pressure-jet cleaning by a pulse of high pressure compressed air in order to remove dust from the bag. In this type of dust collection, the filter bags are suspended from a tube sheet at the top of the collector and are internally supported by cylindrical wire cages to prevent them from collapsing. The short air burst enters the top of the bag tube, which is about 0.1 second and it takes about 0.5 seconds for the shock wave to travel down the length of the bag. The blast of compressed air must be powerful enough to ensure that the shock wave will travel the entire length of the bag and fracture the dust cake. This will cause a brief controlled inflation of the filter to dislodge the accumulated dust cake into the collection facility. Due to its rapid release, the blast of air does not interfere with contaminated gas flow. Therefore, pulse jet baghouses can operate continuously and are not usually compartmentalized.

Advantages

Cleaning mechanism allows bag filters to be cleaned while the system is online.

More complete cleaning than shaker or reverse air baghouses, lengthening bag life.

Operates at lower pressure drops and with lower space requirements.

Disadvantages

Requires the use of dry compressed air.

Requires special fabrics for higher temperatures.

Cannot tolerate high moisture levels or humidity in exhaust gases.
