Equipment introduction

The self-cleaning air filter is a new type of high-efficiency air filter with automatic dust cleaning function. It is especially suitable for long-term and continuous air purification of air-using equipment under frequent conditions. It can effectively filter out dust in the production process. The emissions contain fine pollutants.

Application scope    

Suitable for air compressor stations, oxygen generating stations, air conditioning and air supply systems, gas turbines, blast furnace blowers and other industries    

filter media    

Air particles, impurities, etc.    

working principles

When aerodynamic equipment inhales air containing dust, it will cause wear and tear on the equipment. The inhaled dust will scale on the surface of the fan blades, causing the dynamic balance imbalance accuracy of the rotor in the equipment to decrease, greatly shortening its working life. Harmful chemical components can cause equipment to rust and corrode. Therefore, aerodynamic equipment must be equipped with high-precision air filters. ZKL series self-cleaning air filters are improved and perfected based on the air intake requirements of similar air compressors at home and abroad. The current product performance fully meets the air intake requirements of industrial gas turbine blast furnace blast air compressors.

Filtration process: Dust-laden air is sucked in from the primary coarse filter box  by the air compressor, and passes through the high-efficiency filter cartridge . Due to the comprehensive effects of gravity inertia, diffusion, contact retention, etc., the dust is adsorbed on the high-efficiency filter cartridge , the clean air enters the Venturi tube  through the sealing gasket , goes to the clean air chamber  and merges into the air collection port , and is then sucked into the air compressor from the clean air outlet pipe .

Self-cleaning process: After the dusty air is filtered, the dust is adsorbed on the high-efficiency filter cartridge, and the PLC performs the backflush self-cleaning process according to the set time sequence. When the resistance loss value exceeds 600 Pa, the PLC performs the backflush self-cleaning process according to the differential pressure sequence. Control the backflush self-cleaning process (backflush time is 0.1-0.2 seconds). Other high-efficiency filter cartridges work as usual, and dust is blown back and self-cleaned.

Equipment advantages

a dust box, dust screen, and water flushing dust removal method can be added to the bottom according to user requirements to solve secondary pollution.

high degree of automation: The main components are imported, enabling unmanned operation and saving labor costs.

Made of high-quality materials: Backflushing air consumption is small, generally 0.1 ~ 0.3m3/min (inhalation state); pressure is 0.4 ~ 0.6Mpa.

long lasting: The equipment is light in weight, 1/3-1/2 of the same capacity as the bag type.
