Dust Characteristics: Iron ore dust Solution: Multiple PFV/PFF Series Downflow Cartridge Dust Collectors (Total Airflow: 1,074,000 m³/h). Key Achievements: Handles large air volumes with continuous, stable pulse-jet cleaning and >99.99% efficiency on sub-micron dust (emission ≤10 mg/m³). Custom-designed ducting and system layout prevents dust buildup and effectively controls fugitive emissions.  

Dust Characteristics: Mixed PVC-based flammable/explosive dust. Solution: PFV32 + PFV4 Downflow Cartridge Dust Collectors (Total Airflow: 17,700 m³/h). Key Achievements: Integrated fire protection with water deluge, temperature sensors, and alarms interlocked with the PLC. Comprehensive explosion safety: flameless venting, isolation valves on ducts, anti-static components, and grounding. Uses flame-retardant, anti-static filter media. System operates in automatic sync with the production line or manual mode.  

Dust Characteristics: Powder from shredding/grinding plastic waste, primed with zinc-based powder. Solution: PFC HE80 Cyclone + PFV80 Downflow Cartridge Dust Collector (Total Airflow: 100,000 m³/h). Key Achievements: Replaced a problematic horizontal cartridge system prone to clogging and fire hazards; the new fireproof/explosion-proof system runs flawlessly. The pre-cyclone removes plastic scraps, extending filter life. Uses anti-static, wide-pleat, spun-bond polyester filter media. Enhanced safety with IEP GE arched explosion vents, fire dampers, and shipped as pre-assembled units for easy overseas installation.
