JHF Type Pulse Jet Flat Bag Dust Collector

The JHF-type pulse jet flat bag dust collector is an advanced dust removal system designed for efficient air filtration across a wide range of industries. With its compact footprint and simple, rational structure, it is suitable for both indoor and outdoor installation, offering a powerful and space-saving solution for particulate control.

✅ Applications

JHF dust collectors are widely used for dust filtration and particle recovery in industries such as:

• Machining and metalworking
• Foundry and sand cleaning
• Metallurgy
• Chemical production
• Building materials and refractory processing
• Food and grain handling
• Pharmaceutical manufacturing
• Arc furnaces and processes generating fine and light dust
• Valuable dust recovery systems

🔧 Working Principle

Dust-laden air enters the filter unit through the inlet duct, where dust particles are captured on the external surface of flat filter bags. Clean air flows into the internal cavity of the bags and exits through the upper plenum and outlet ducts.

When the system detects pressure loss or reaches a timed interval, the pulse jet cleaning system activates. High-pressure compressed air is released into long Venturi tubes, causing a sudden reverse air surge inside the bags. This expands the bags rapidly, shaking off dust cake layers into the bottom hopper for discharge and collection via a screw conveyor.

The JHF unit typically includes:

• Differential pressure control devices (e.g., pressure transmitters)
• Time relay-based pulse controllers
• Electromagnetic pulse valves that initiate sequential cleaning pulses

This controlled cleaning ensures low operating resistance, continuous filtration performance, and longer filter life.
