The precision filter adopts a shaped filter material. Under the action of pressure, the raw liquid passes through the filter material, the filter residue remains on the tube wall, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration.
Structure: filter cloth, filter screen, filter disc, sintered filter tube, wire wound filter element, melt blown filter element, etc. Due to the different filter materials, the filter pore size is also different.
Product Description:
The precision filter is a shaped filter material. Under the action of pressure, the raw liquid passes through the filter material, the filter residue remains on the tube wall, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration. Structure: filter cloth, filter screen, filter disc, sintered filter tube, wire wound filter element, meltblown filter element, etc. 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, and the filtration pore size is generally in the range of 0.5~120μm. The same form of filter material can be divided into different specifications according to the external size. There are two types of wire-wound filter elements (also known as honeycomb filter elements): one is polypropylene fiber---polypropylene skeleton filter element, the highest temperature is 60℃; the other is absorbent cotton fiber---stainless steel skeleton filter element, the maximum service temperature is 120℃ °C. The melt-blown filter element is made of polypropylene as a raw material and is formed by a melt-blown process. The maximum working temperature is 60 °C. Precision filtration can remove suspended solids, some colloidal substances and small particles in the stock solution.
working principle:
The precision filter is generally set before the pressure vessel to remove fine particles with a turbidity of more than 1 degree to meet the requirements of the filtrate in the subsequent process; sometimes it is also set at the end of the entire filtrate processing system to prevent fine particles (such as broken resin) into the finished water or solution.
Most of the precision filters are made of stainless steel with a filter element (such as PP cotton) inside, which are mainly used after multi-media pretreatment and filtration and before reverse osmosis, ultrafiltration and other membrane filtration equipment. It is used to filter out fine substances (such as tiny quartz sand, activated carbon particles, etc.) after multi-media filtration to ensure the accuracy of water filtration and to protect the membrane filter element from being damaged by large particles. The precision grades of the filter cartridges installed in the precision filtration device can be divided into 0.5μs, 1μs, 5μs, 10μs, etc. Different filtration precisions are selected according to different application occasions to ensure the accuracy of the rear effluent and the safety of the membrane elements of the latter stage.
