Pulse-Backwash Intelligent Air Purification System - Industrial Intake Safety Barrier

Product Introduction

1. Adopts pleated anti-static filter cartridges and high-frequency pulse backwash technology, with a filtration efficiency of 99.99% for 0.3μm particles, suitable for harsh working conditions with dust concentration ≤1000mg/m³.

2. Modular box design supports customization of air volume from 1000 to 100,000m³/h, equipped with a PLC intelligent control system to achieve automatic ash cleaning in dual modes of differential pressure/timing.

3. Widely used in scenarios such as metallurgical blast furnaces, gas turbines, and electronic clean workshops to protect key equipment from dust wear and pollution.

Working Process

1. Dusty Air Treatment: Air is evenly distributed through the inlet guide plate, and the inertial settling chamber removes ≥10μm large particles.

2. Multi-Stage Filtration Stage:

• Primary pre-filter layer: Intercepts 5-10μm dust, reducing the load on the main filter cartridge;

• Main filter cartridge fine filtration: PTFE coated filter media captures 0.3μm particles, forming a dust filter cake layer.

3. Pulse Backwash Ash Cleaning:

• When the differential pressure ≥1200Pa or timing (1-120min adjustable), the electromagnetic pulse valve opens;

• 0.4-0.6MPa compressed air instantly impacts the filter cartridge in the reverse direction, shaking off dust into the ash hopper.

4. Dust Collection and Discharge: The ash hopper is equipped with a screw conveyor to periodically transport dust to the dust collection bag or external treatment system.

Product Features

1. Ultra-High Efficiency Filtration: Reaches ISO 16890 ePM10 level, with outlet dust concentration ≤1mg/m³, meeting the intake requirements of precision equipment.

2. Low Resistance and Energy Saving: Optimized filter cartridge pleat count and airflow path, initial resistance ≤800Pa, annual energy consumption saved by 20-30%.

3. Explosion-Proof and Anti-Static: Filter media added with conductive fibers (surface resistance ≤10⁹Ω), and the box grounding design prevents static accumulation.

4. Maintenance-Free Design: Filter cartridge life ≥20,000 hours, quick-install structure enables 30-minute fast replacement.

Technical Parameters

FAQ

Question 1: How to maintain filter efficiency in humid environments?
Answer: Use hydrophobic PTFE-coated filter cartridges and install an optional electric heater (5-10℃ above dew point) to prevent filter cake caking. Regularly check the drain valve for moisture accumulation in the air tank.

Question 2: Can the system handle explosive dusts (e.g., aluminum powder)?
Answer: Yes, the explosion-proof model features anti-static filters, explosion relief panels, and grounding monitoring. It is recommended to use nitrogen purging and limit dust concentration below 50% of the lower explosive limit.

Conclusion

The Pulse-Backwash Intelligent Air Purification System sets a new standard for industrial air filtration, combining HEPA-level efficiency with intelligent automation. Its robust design ensures continuous operation in the harshest environments, protecting critical equipment and improving process reliability while minimizing energy consumption and maintenance needs.
