Bag filters are used for dust purification sizing 1 micron at industries, and if designed properly, they provide %99 refinement efficiency. Bag filters are designed and manufactured in two types of Jet Pulse and Reverse Air for mine and asphalt industries by this company. These filters have application in different mine industries, asphalt, plaster, tile, chinaware, mechanized powders and wood industry factories etc.
Jet Pulse Model
In this model, bags are located in a parallel position inside a case and dust stream passes through them. Dust is transferred towards the machine by canals and the exhaust fan. The dust is absorbed by the bags, and the purified air enters into the exhaust fan and then removes. Bags’ recovery operation in this method is accomplished by the entrance of compressed air with pressure for 7 to 8 times through the electric faucet, pipes and venturi mechanism which causes severe turbulence, shock and eventually bags recovery. In this method, dust removing operation is done in an online status.
Reverse Air Model
In this model, due to not needing a processed compressed air (compressed air’s production and maintenance are costly), the bags’ recovery would bear low depreciation and high efficiency by creating a reverse airstream. And the bags will function in lower temperatures and will have longer lifetime due to their recovery applied by the atmosphere. In this method, dust removing operation is done in an offline status.
