Product introduction:

Self-cleaning air filter is a new type of high efficiency air filter with automatic ash cleaning function, especially suitable for long-term and continuous air purification of gas equipment under multiple conditions, and can effectively filter out the emission of small pollutants in the production process.

Technical Parameters:

product feature:

1, high degree of automation: the main components are imported parts, which can realize unmanned operation and save labor costs

2, the use of excellent materials: back blowing less air consumption, generally 0.1 ~ 0.3m3/min(inhalation state); The pressure is 0.4 ~ 0.6Mpa;

3, long service life: light weight, is the same capacity of cloth bag 1/3-1/2.

Work principle:

After the aerodynamic equipment inhales the air containing dust, it will cause the wear of the equipment, and the dust will scale on the surface of the fan blade, causing the dynamic balance of the rotor in the equipment to decrease the imbalance accuracy, so that its working life is greatly shortened, and the harmful chemical components in the dust will make the equipment rust and corrosion. Therefore, the aerodynamic equipment must be equipped with high-precision air filters. ZKL series self-cleaning air filter is improved in the domestic and foreign similar air compressor intake requirements, the current product performance fully meet the industrial gas turbine blast furnace blast air compressor intake requirements.

Filtration process: The dust-containing air is aspirated by the air compressor, inhaled from the primary coarse filter box (1), through the high efficiency filter cylinder (2), due to the combined effect of gravity inertia, diffusion, contact retention, etc., the dust is adsorbed on the high efficiency filter cylinder, the clean air enters the Venturi tube (4) through the sealing washer (3), to the clean gas chamber (5) to the air collector (6), and then is inhaled by the air compressor from the clean gas outlet pipe (7).

Self-cleaning process: After the dust air is filtered, the dust is adsorbed on the high efficiency filter cylinder, and the reverse blowing self-cleaning process is carried out by PLC according to the set time order. When the resistance loss value exceeds 600 pa, the reverse blowing self-cleaning process is controlled by PLC according to the differential pressure order (the reverse blowing time is 0.1-0.2 seconds). Other high efficiency filter cartridges work as usual, and the dust is blown back to clean itself down

FAQ:

Q: What filtration accuracy does it have?

A: It can filter down to 10 micron particles with high filtration accuracy, meeting the requirements for industrial gas intake.

Q: How does the self-cleaning function work?

A: It uses reverse pulse blow technology. When the pressure differential reaches 600Pa, compressed air is released through nozzles to blow dust off the filter cartridge, keeping the filter clean and maintaining high efficiency.

Q: How long is the service life?

A: The filter has a long service life due to the use of durable filter media and automatic self-cleaning function to remove dust build-up. However, the actual service life depends on operating conditions and dust loading.

Q: What industries does it apply to?

A: It is used in industrial applications that require clean intake gas, especially in chemical plants, metallurgy, petrochemical and power generation industries.

Q: How is the filtration process?

A: Dusty air enters the coarse filter box first, then passes through the high efficiency filter cylinder where dust particles are captured. Clean air then enters the Venturi tube and enters the clean air chamber.

Q: When does the self-cleaning start?

A: When the pressure differential across the filter reaches 600Pa, the PLC controller will activate the solenoid valves to release compressed air for backwashing the filter cartridge for 0.1-0.2 seconds, removing dust that has accumulated.

Q: What is the filter medium?

A: The filter medium is designed to remove dust from industrial applications, suitable for filtering dust from chemical,metallurgical and petroleum processes.
