Hitech Bag Filter consists of a number of tubular filter bag sleeves arranged in a square of rectangular matrix. These sleeves are supported from inside on steel wire cages to prevent them form collapsing. The dust laden air is drawn through the filter bag sleeves by an externally connected Centrifugal Fan and thereby dust gets collected on the outside surface if the filter bag sleeves. The sleeves are periodically cleaned by short blasts (Pulse) of compressed air. These blasts are in the opposite direction to the flow of dust laden air This reverse flow flexes the fabric bags away from the cages and loosens the dust cake collected on to bags and the process is repeated for every row of bags. The filter media (standard fabric) is synthetic and non-woven needled felt.

The suiting filter fabrics/media are available for different air/gas temperatures (up to 200 deg) and as per the application requirement. Apart from High ratio (Pulse jet) Bag filters, low ratio Bag filters of mechanical shaking type are also offered for specific applications.

Operating Principle:

The dust laden gases enter the bag filter form the hopper. The gases pass through the bags while the dust is trapped on the outside, forming a dense filter cake. This Filter cake has to be removed to maintain continues and uninterrupted filtration.

This is done by injecting a shot blast of compressed air inside the bag (in the direction opposite to that of filtration) thus dislodging the filter cake form the bags. This generates fresh surface for filtration to resume. At any given time, one set of bags are cleaned while the rest of the bags do the filtration. This type of design dislodged dust is removed form the bad filter by the rotary air lock or collected in dust bin.

Selection and Sizing:

Sizing of a pulse jet fabric bag dust Collector unit is a highly precision job and call for years of exposure to the applications before attaining expertise. However, to beginners the data enclosed in the annexure tables shall be found of great use. Case shall always be taken in keeping a safety Margin to over size the selection and this margin shall also be increased/reduced with feel of the material's physical nature specially fineness. An overall chart covering material A to Z, and indicating the recommended Filtration velocities have been enclosed herewith for timely use of the application engineers. However, correction factors shall be before sizing the dust collector unit.
