Description
Negative Pressure Baghouse Dust Collection System
1. Definition & Working Principle

Negative pressure dust collection system refers to the configuration where the fan is installed after the dust collector. The fan sucks the dust-laden flue gas through the dust collector, where filtration occurs under negative pressure, and the purified gas is pushed by the fan into the chimney for discharge.

The fan creates negative pressure inside the dust collector, drawing in dust-laden gas for filtration; purified gas is discharged through the fan.

2. JDDM Series Long-Bag Low-Pressure Pulse Dust Collector Parameters

JDDM series negative pressure pulse dust collector is the mainstream equipment for SAF flue gas purification, adopting long-bag low-pressure pulse technology.

Parameter Specification Range
Air Flow Rate Customized according to SAF capacity, can reach over 180,000 m³/h
Filtration Area Half of glass fiber baghouse filtration area, over 4,000 m²
Filter Bag Specification φ130-160 * 6000-7000 mm
Equipment Weight 50% lighter than traditional glass fiber baghouse
Filtration Velocity About 1.0 m/min, twice that of glass fiber filter material
Equipment Resistance <2,000 Pa (design value about 1,500 Pa)
Working Mode Negative Pressure, the fan is installed after the dust collector
3. Advantages
  • Low investment - filtration area is half of glass fiber baghouse, equipment weight 50% lighter
  • Small footprint - filtration velocity doubled, equipment volume significantly reduced
  • Excellent cleaning effect - large submerged straight-through pulse valve, injection pressure up to 2000Pa
  • Convenient maintenance - top cover structure, bags can be replaced by removing the top cover
  • Long bag life - new composite filter material lasts 18-24 months (glass fiber only 8-12 months)
  • Stable fan operation - fan operates in clean air environment, blades require no cleaning
  • Long pulse valve life - diaphragm service life up to 1 million cycles
4. Negative Pressure Selection Scenarios
Application Scenario Description
Large SAF Large SAF above 25000kVA, large flue gas volume
Strict Environment Requiremnet Strict emission standards, need stable compliance
High automation High automation requirement, reduced manual maintenance
Fan maintenance is difficult Sites where fan maintenance is difficult
Large new projects Large new projects with sufficient investment and long-term reliability focus
5. System Comparison Table
Comparison Item Positive Pressure Large Baghouse Negative Pressure Large Baghouse
Fan Position Before dust collector (upstream) After dust collector (downstream)
Collector State Positive pressure Negative pressure
