Pulse Jet Baghouse Dust Collector

Pulse Jet Baghouse Dust Collector is a high-efficiency industrial dust removal equipment that uses instantaneous compressed air pulses to clean filter bags,enabling continuous online operation.

Operating Parameters&Precautions

Compressed Air System

Maintain stable pressure at 0.4–0.7 MPa.Insufficient pressure causes incomplete cleaning;excessive pressure damages filter bags.

Air supply must be dry and oil-free(dew point≤-20°C).Install dryers and filters to prevent bag clogging and hardening.

Regularly drain condensate from air tanks and pipelines.

Filter Bag Management

Select bag materials(polyester,PPS,fiberglass)matching temperature,humidity and chemical properties of exhaust gas.

Avoid temperatures exceeding material limits;prevent condensation to avoid dust caking on bags.

Install bags carefully without damage or wrinkles;ensure good sealing with tube sheet.

Monitor pressure difference(normally 1000–1500 Pa).Significant increase indicates bag clogging;sudden decrease suggests bag damage or leakage.

Pulse Cleaning System

Set proper pulse width(0.1–0.2 seconds)and interval based on dust concentration.

Use interval grouping for cleaning;avoid adjacent bags in the same group to prevent re-entrainment.

Regularly inspect pulse valves,solenoids and diaphragms;replace damaged parts promptly.

Control system should support differential pressure control mode for optimized cleaning.

Ash Discharge System

Maintain continuous operation of screw conveyors,rotary airlocks,etc..

Ensure hopper slope≥60°for smooth dust flow.

Prevent excessive dust accumulation in hoppers to avoid bag erosion and secondary dust entrainment.

Safety&Maintenance

Explosion-proof requirements:For combustible dust,install explosion vents,flame arresters,and reliable grounding(resistance≤4Ω).

Maintenance safety:Disconnect power,release air pressure,ventilate and test oxygen content(19.5%–23.5%)before entering the housing.

Daily inspections:Check seals,monitoring instruments,fans and abnormal noises.

Regular maintenance:Replace aging seals,lubricate bearings,calibrate instruments,and overhaul components periodically.

Advantages

High efficiency:Dust collection efficiency>90%for fine particles.

Online cleaning:Continuous operation without shutdown during cleaning.

Wide applicability:Handles various dust types and concentrations.

Stable performance:Low maintenance and reliable long-term operation.

Typical Applications

Widely used in cement,steel,power plants,mining,chemical,food processing and pharmaceutical industries for flue gas purification and dust collection.
