Off-Line Pulse Jet Bag Filter consists of a series of modules / chambers. Each module is isolated from the gas stream by closing the outlet damper in a predetermined sequence. In an insulated module, each row of filter bags is sequentially cleaned with pulses of compressed air. The air mass contributes to the downdraft by drawing air from the tubes.
The extracted powder falls into the hoppers and is discharged through the discharge valve. A master controller, which can be PLC based, determines the order of rooms that should be in “Off-Line Mode”.
Cabin Jet Pulse Filter bag systems are generally suitable for large volumes or light dust applications. These bag systems are robust. One of the main advantages of the Off-Line bag system is that the system can be maintained by “turning off” a module until the maintenance activity is complete.
