Pulse Jet Bag Filter
Pulse Jet Bag Filter is the most demanded equipment in industries for providing clean air. We make available these bag filters in two models as online and offline. The online jet filter is designed for low-to-medium gas volume, while offline is employed for larger. While cleaning the bags, the gas flow to a compartment of the filter is stopped temporarily. In the absence of gas in filter compartments, dust dislodged from bags settle down quickly in the hoppers. There are several other compartments in the filter bags that are active during this cleaning process, filtering the gases as usual. Each and every compartment in the filter is cleaned one by one automatically with a sequence controller.
Online Pulse Jet Bag Filters
In an online bag filter, bags are cleaned row by row, even when the dust laden gas is filtered. The sequence of cleaning is controlled automatically by a sequence controller. This operates the assembly of solenoid and pulse valves which direct the air flow into the manifolds. The holes are jig drilled for perfect alignment with the venturi centre for achieving maximum cleaning efficiency.
Pulse Jet Bag Filters
This mode incorporates the advantages of pulse jet bag filters, as well as that of a reverse air bag house. Each compartment is similar to an online pulse jet bag filter. The cleaning process consists of sequentially isolating each compartment and cleaning it with compressed air. All compartments are then cleaned automatically. Offline cleaning is suitable for light and fine dust, and for larger volumes where the occurrence of fluidisation is a distinct possibility.
The offline bag filter contains 4 to 6 bag filter compartments. Each compartment is similar to online bag filter. Gas flow through a compartment is stopped temporarily when the pulse cleaning of the bags is to be done. The dust dislodged from bags settles quickly in the hoppers because of absence of gas movement in the bag filter compartment. During this time the remaining compartments keep filtering the gases as usual. Each compartment is cleaned one after another in same manner.
The starting and stopping of gas flow through individual compartments is achieved through a compact pneumatic damper system. Generally the offline bag filter is employed for larger gas volumes.
