Frequently Asked Questions
Common Questions About Bag Filter / Pulse Jet Bag Filter
Find answers to the most common questions asked by our clients.
Operating principle: (1) Filtration cycle: Dusty air enters plenum chamber, passes through filter bags (outside to inside), dust collects on bag exterior forming dust cake, clean air exits through bag interior to clean air plenum and exhausts via blower. (2) Cleaning cycle: Compressed air pulse (80-100 PSI, 0.1 second duration) shoots down bag interior, creating shockwave that flexes bag fabric outward. This dislodges dust cake which falls into hopper. (3) Pulse sequence: Automated sequential cleaning - only 5-10% of bags cleaned at a time to maintain airflow. Cleaning triggered by differential pressure (typically 125-175 mmWC) or timer. Efficiency: 99.5-99.9% for particles >0.5 micron. Advantage over shaker/reverse-air: Online cleaning (no shutdown needed), smaller footprint, lower pressure drop.
Polyester: Most common, temp <135°C, cost-effective (₹800-1,500/bag), resistant to most acids, good for general applications. Polypropylene: Excellent chemical resistance, temp <90°C, ideal for chemical/pharmaceutical applications with corrosive fumes. Aramid (Nomex): High temp 180-200°C, excellent for hot gas filtration (asphalt plants, dryers), cost 3-4× polyester. PTFE (Teflon): Temp 240-260°C, chemical resistant, very low surface energy (dust doesn't stick), premium cost 5-7× polyester, used pharmaceutical/food where hygiene critical. Fiberglass: Temp 260-280°C, brittle (requires gentle handling), cement plants, high-temp exhaust. Selection factors: Operating temperature (most critical), chemical exposure, moisture level, abrasiveness, required filtration efficiency. We provide bag material selection consultation based on your specific dust and gas analysis.
Common causes in order of likelihood: (1) Bags blinding: Dust particles embedding in fabric (not just sitting on surface) - caused by oils/moisture in air, sticky dust, or too-fine particles. Solution: change bag material, add pre-filtration, improve pulse cleaning. (2) Inadequate pulse cleaning: Low compressor pressure (<80 PSI), pulse valves failing, timer settings too long between cleanings. Solution: verify compressed air system, test pulse valves, shorten cleaning intervals. (3) Excessive dust loading: CFM too high for filter area (air-to-cloth ratio >6:1), too many machines on one collector. Solution: reduce airflow or add filter bags. (4) Bag damage: Holes allowing dust bypass and re-collection. Solution: inspect bags, replace damaged. (5) Hopper not emptying: Dust re-entraining from overfull hopper. Solution: empty more frequently, check rotary valve. Normal operating pressure: 75-150 mmWC. Replace bags when exceeds 200 mmWC consistently.
Yes, with proper safety features: Explosion venting: Relief panels (explosion doors) on collector housing - rupture before housing fails, directing explosion upward safely. Size per NFPA standards based on collector volume. Spark detection/suppression: Sensors in inlet duct detect sparks, trigger water spray or isolation damper before sparks enter hopper. Essential for woodworking, metalworking. Grounding/bonding: All components electrically bonded, proper grounding prevents static buildup. Bags with conductive threads. Inert gas atmosphere: Nitrogen purge for highly combustible dust (aluminum, magnesium). Continuous monitoring: Temperature sensors in hopper detect smoldering, trigger alarm/suppression. Regular cleaning: No dust accumulation outside filters (fuel for secondary explosion). Combustible dust examples: wood dust, metal powders, grain dust, sugar/flour, coal dust, certain plastics. Critical: NFPA 652/654 compliance mandatory - improper design is life-safety violation.
Compressed air consumption depends on size and cleaning frequency: Small collector (10-20 bags): 1-2 CFM average at 90 PSI, periodic pulses totaling 30-60 seconds/hour. Medium collector (40-100 bags): 3-8 CFM average, 60-120 seconds total pulse time/hour. Large collector (100-300 bags): 8-20 CFM average, 2-5 minutes total pulse time/hour. Cost: Compressed air expensive - typically ₹0.30-0.50 per m³ generated. Annual air cost can be ₹50,000-2,00,000 for large collectors. Optimization: Use minimum effective pulse pressure (80-90 PSI instead of 100+), pulse on-demand (differential pressure trigger) vs timer, regularly maintain pulse valves (leaks waste air), properly size tanks (minimum 10× pulse volume to prevent pressure drop). Compressor sizing: Dedicated compressor not usually needed - most facilities have plant air. Require 100-200 liter receiver tank near collector to handle pulse surge demand.
