Introduction of Filter Design Technology

Different filter design technology has common goal like improving the working efficiency. According to filter dust removal mechanism, common Air filters can be divided into dry type and wet type two kinds. Wet filters such as chain belt type and ring type filter rely on the oil film adhesion dust in the atmosphere to achieve the purposes of dust filtering. Dry filters such as dry belt, cloth bag, box plate and cartridge filter are popular with the unique conditions. Their filtering principle is the air through a variety of plants and animals or chemical fiber fabric lining with gravity, inertia diffusion, contact surface choke and electrostatic adsorption effect to make the dust in the air. The stranded on the outer edge of the filter material (internally establishing a dust film), with the purpose of dust removal.

The filter technology must be corresponding to our life. Along the Yangtze river in the south of China, coastal areas or foggy areas (like Chang Ding) relative humidity is bigger. On the selection of the filter, filter cartridge will adapt to the local climate conditions. To increase the actual processing with a rich amount of gases should choose composite Filter cartridge (20% polyester and 80% wood pulp fiber). Filter paper chooses the HV, German MANN company or other large tensile strength, high stiffness of waterproof model imported filter paper. In addition, in the northwest of China, Inner Mongolia, An Nu, He Nan and other places, the climate is dry with low relative humidity. Due to the destruction of the ecological environment, the dust weather in the region is serious. The sandstorm weather often occurs in the spring and autumn. Air dust content and long duration of the self-cleaning filter resistance high situation happen frequently. To reduce the running resistance to prolong the cycle filter cartridge, we have international KOD56 compressor matching self-cleaning filter as filter design technology which is put forward with the following countermeasures.

High efficiency self-cleaning filter of high precision, automatic programming counter blowing dust and convenient management can realize non-stop cartridge replacement, which has been widely used in iron and steel, petrochemical, air separation equipment, fertilizer, pharmaceutical and other industries like Filter technology. For frequent continuous rain, continuous heavy fog, dust and other special weather area according to different weather characteristics, we should choose supporting self-cleaning filters. The device also should be added when putting rich processing air amount, choosing appropriate cartridge filter material, improving the self-cleaning and stable back pressure and reasonable control or regulating measures for the filter technology. It can avoid a self-cleaning filter resistance which happens continuously, extends the lifetime of filter cartridge and reduces the running cost to ensure the normal operation of air compressor.

Higher request for some of the compressor and gas turbine for filtering level, in order to achieve H12 level above, we'd better use triple filter. Its use level of filter is secondary self-cleaning filters. Level 3 by high or super efficient frame Filter will prevent moisture from entering the entrance. At the same time, reducing the load stress at all levels will improve the filtering accuracy according to filter technology.
