Energy-Saving Pulse Bag Dust Collector for Industrial Applications

The Pulse Jet Baghouse Dust Collector is a high-efficiency dry filtration system engineered to capture fine, high-concentration dust generated in foundry processes—such as shakeout, sand mixing, reclamation, electric furnace melting, and material conveying. Utilizing high-pressure pulse-jet cleaning technology and ePTFE membrane filter bags, it achieves 99.99% filtration efficiency for particles ≥0.3μm, with emissions consistently below 10 mg/m³ It is the cornerstone of ultra-low-emission solutions in modern green foundries.

Dusty Air Inlet: Gas enters the housing; coarse particles settle into the hopper by gravity.
Bag Filtration: Fine dust is captured on the surface of ePTFE membrane bags; clean air passes through to the clean plenum.
Pulse Cleaning: PLC triggers solenoid valves based on timer or differential pressure. A 0.5–0.7 MPa compressed air pulse creates a high-velocity reverse jet via Venturi nozzles, causing bags to snap outward and dislodge dust cake—without interrupting operation.
Dust Discharge: Collected dust falls into the hopper and is removed via rotary valve or screw conveyor.

Ultra-Low Emissions – Eco-Certified
Imported ePTFE membrane bags enable surface filtration—eliminating re-entrainment. Emissions ≤10 mg/m³, compliant with global environmental standards.

Smart Cleaning – Energy Efficient
Dual-mode (timer + differential pressure) cleaning reduces compressed air use by 30%. Adjustable pressure extends bag life to 2–3 years.

Modular & Scalable
Standard modules: 3,000–20,000 m³/h. Multi-chamber parallel design scales up to 500,000 m³/h—ideal for small shops to mega-foundries.

High-Temp & Corrosion Resistant
Bag options: 130°C (standard), 190°C (Nomex), 260°C (PPS/P84), or 300°C (fiberglass)—suitable for electric furnace fumes and hot sand applications.

Explosion-Safe Design
Optional explosion vents, spark detection, CO monitoring, and auto-suppression—compliant with ATEX / NFPA 69 for combustible dust (e.g., Al/Mg alloys).

Foundry Shop: Dust collection at shakeout, mixers, coolers, conveyors
Melting Area: Fume extraction from induction furnaces, aluminum melters
Reclamation Line: Dust control at crushing, screening, magnetic separators
Material Handling: Silos, hoppers, transfer points
