Self-cleaning Air Filter for Air Compressor Stations, Oxygen Generation & Gas Turbine Industries

Working Principle

• Filtration process: Dusty air is sucked in through the primary coarse filter box, then passes through the high-efficiency filter cylinder. Dust adheres to the high-efficiency filter cylinder under comprehensive effects of gravity, inertia, diffusion and contact retention. Clean air enters the venturi tube through the sealing gasket, converges to the gas collecting port and is sucked into the air compressor.

• Self-cleaning process: After filtration, dust is adsorbed on the high-efficiency filter cylinder. The PLC controls the pulse valve to perform reverse self-cleaning in sequence by time or differential pressure (when the pressure loss exceeds 600 Pa, the self-cleaning process is triggered, with a reverse blowing time of 0.1-0.2 seconds). Other filter units work normally during cleaning, ensuring continuous air supply.

Advantages

1. Intelligent control: Three self-cleaning modes available: timing, differential pressure and manual, controlled by an intelligent distributor.

2. Automatic cleaning: Realizes automatic cleaning of filter elements without affecting normal operation of other filter units.

3. Reasonable design: No-bend pipe and high-level stacked combined type, convenient and quick to install.

4. Long service life: Under general environmental conditions, the replacement cycle of filter elements can reach about 2 years.

Application

• Air compressor station: Pre-filtration and purification of air intake.

• Oxygen generation station: Air purification for oxygen production.

• Air conditioning system: Air supply filtration for large buildings.

• Gas turbine: High-precision air intake filtration.

• Blast furnace blower: Dust removal and purification of blast furnace air.
