Pulse Jet Bag Filter is a pneumatic pulse-jet system that provides continuous, automatic bag cleaning. On a timed cycle, a burst of compressed air is directed down through a venture at the top of the bag. This includes cleaning air into the bag and setting up a pneumatic shock wave inside it. The airflow through the bag is momentarily stopped, the bag is firmly flexed, causing the accumulated dust particles to drop off the bag into the hopper. Since only a few rows of bags are cleaned at a time there is no interruption of airflow through the filter. This provides a smooth operating dust control or material handling system.

Operation

Dust-laden air enters the Dust collector through the hopper or casing depending upon the application
An internal baffle distributes the dirty air within the housing. Dust-laden air slows down as it enters the collector
Production plants for cement, limestone, and gypsum kilns, mills, driers, and coolers
Coarser dust particles drop into the hopper
The air dirty passes through the bags, and dust is captured and collected on the bag’s exterior
Filtered clean air flows to the clean air chamber and exhausts through the outlet
Periodic compressed air pulsing removes accumulated dust from the bags with cleaning frequency and duration adjusted by solid-state timers or PLC
Dust falls into the hopper for collection through the discharge device

Advantage

Easy installation Depending on size, the unit is shipped fully assembled or in PANEL form for quick and easy field erection, and low field labor cost.
Reduced energy cost Adjustable Cleaning mechanisms based on system pressure drop maintain low-pressure drop, with minimum compressed air consumption.
Reduces energy costs.
Quick Bag replacements Snap band arrangements of fixing filter bags and cages are designed for easy installation, quick replacement.
Minimal Maintenance No internal moving parts. Maintenance is reduced. Dust collector shutdown is minimized.
Increased Bag life Optimizes bag cleaning mechanism and reduced compressed air usage enhances bag life.
Periodic compressed air pulsing removes accumulated dust from the bags with cleaning frequency and duration adjusted by solid-state timers or PLC
Dust falls into the hopper for collection through the discharge device
