Introduction

Self-cleaning air filter lefilter

Self-cleaning air filter

Self-cleaning air filter is a new type of high-efficiency air filter with automatic dust removal function. It is especially suitable for long-term and continuous air purification of air-consuming equipment under multiple conditions. Process emissions contain fine pollutants.

application Suitable for air compressor station, oxygen production station, air-conditioning air supply system, gas turbine, blast furnace blower and other industries
filter media Air particles, impurities, etc.

Working principle

After the aerodynamic equipment inhales dust-containing air, it will cause wear and tear of the equipment, and the inhaled dust will scale on the surface of the fan blades, resulting in a decrease in the dynamic balance accuracy of the rotor in the equipment, and its working life is greatly shortened. 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 in the air intake requirements of similar air compressors at home and abroad. At present, the product performance fully meets the air intake requirements of industrial gas turbine blast furnace blast air compressors.


Self-cleaning air filter working principle

Filtration process: The dust-laden air is sucked by the air compressor, sucked from the first-stage coarse filter box ①, and passed through a high-efficiency filter. Filter cartridge ②, due to the combined effects of gravitational inertia, diffusion, contact retention, etc., the dust is adsorbed on the high-efficiency filter cartridge On the upper side, clean air enters the venturi ④ through the gasket garden ③, enters the clean e-room ⑤ and joins the air collecting port ⑥, and then flows from the net The air outlet pipe ⑦ is sucked by the air compressor.


Self-cleaning process: After the dust-laden air is filtered, the dust is adsorbed on the high-efficiency filter cartridge, and the PLC is set according to the set time. The process of backflushing and self-cleaning is carried out in sequence. When the resistance loss value exceeds 600 Pa, the backflushing self-cleaning process is controlled by the PLC according to the sequence of differential pressure. Cleaning process (backflushing time is 0.1-0.2 seconds). Other high-efficiency filter cartridges work as usual, and the dust is blown back down

Advantages

  • Self-cleaning air filter advantage

    Self-cleaning air filter;
    According to the user's requirements, a dust collecting box, a dust-proof net, and a water-washing and dust-removing method.

    intelligent

    Controlled by Smart Distributor:

    There are three ways of self-cleaning, namely
    (1) Timing
    (2) Differential pressure
    (3) Manual

  • Self-cleaning air filter advantage

    This equipment can realize automatic cleaning of air filter elements, so that the equipment can operate.

    automatic

    High degree of automation:

    The main components are imported parts, which can realize unmanned operation and save labor costs

  • Self-cleaning air filter advantage

    Reasonable design, no-bend design, high-rise building block combination type, easy and fast installation;

    fast

    Using high-quality materials:

    low air consumption for backflushing, generally 0.1~0.3m3/min inhalation state; pressure is 0.4~0.6Mpa;

  • Self-cleaning air filter advantage

    Under normal environmental conditions, the filter element replacement cycle can reach about 2 years;

    convenient

    Long service life:

    light weight, 1/3-1/2 of the same capacity as the cloth bag;
