Bag dust collector : pulse jet
Tama S.p.a.
Operating Principle
Polluted air is drawn in below the filtering sleeves through an opening connected to the hopper or through a calming chamber. Much of the dust contained in the intake air precipitates into the collection bin due to the considerable reduction of its flow speed; the air is subsequently conveyed to the sleeves, passing from the outside to the inside and depositing impurities in the collection hopper; clean air is then emitted from inside the sleeves. During this process, the filter is kept perfectly efficient by a system of cyclic, counter-current cleaning. A jet of compressed air, stored in a special tank, is forcefully blown into the sleeves. This creates a violent counter current wave that shakes the sleeve and loosens and precipitates the particles deposited on the outside. A programmed electronic device triggers this jet that is forced through a network of blower tubes inside respective Venturi tubes connected to the filtering sleeves.
