The working principle of the precision filter of the Multi Cartridge Filter Housing
1. Working principle
Precision filters are also called Cartridge Filter Housing. The shell is made of high-quality stainless steel, and the filter element is made of molded filter material PP melt-blown filter element, polypropylene filter element, wire wound filter element, etc. Under the action of pressure, the original liquid passes through the filter material, and the filter residue remains on the filter material. The outflow of the filter material can effectively remove impurities, sediments, suspended solids, and bacteria in the water, thereby achieving the purpose of filtration.
Precision filtration uses a shaped filter material. Under the action of pressure, the original liquid passes through the filter material, the filter residue is left on the wall of the filter material, and the filtrate flows out through the filter material to achieve the filtering purpose.
The formed filter materials are: filter cloth, filter screen, filter disc, sintered filter tube, wire wound filter element, melt blown filter element, microporous filter element and multifunctional filter element.
Due to the different filter materials, the filter pore size is also different. Precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration. The filter pore size is generally in the range of 0.01-120um. Filter materials of the same type are divided into different specifications according to the external dimensions.
PP melt blown filter element: The melt blown filter element is used in large quantities in water purification, has outstanding chemical compatibility, and is suitable for the filtration of strong acids, strong alkalis and organic solvents; it has strong dirt holding capacity, long service life and low cost. The structural feature of PP melt blown filter element is that the fiber fineness is relatively small, usually less than 10 microns, and most of the fiber fineness is between 1 and 4 microns.
Polypropylene filter element is a kind of deep filter element with fixed pore size using ultra-fine polypropylene fiber filter material as the filter medium. The filter accuracy ranges from 0.1µm to 60µm. Its unique low pressure drop, high flow rate and long service life characteristics are The product of choice for pre-filtering. It is not only used in large quantities for water purification. It also has outstanding chemical compatibility and is suitable for the filtration of strong acids, strong alkalis and organic solvents.
The wire-wound filter element (wound type) absorbent cotton filter element can effectively remove suspended solids, particles, etc. in the liquid, can withstand higher filtration pressure, the filter pore size is large and small, and has excellent deep filtration effect, good compatibility and High filter residue load capacity, can be made of a variety of materials to meet the needs of various liquid filtration
