Product Description
Precision filter, also known as security filter, is generally set in front of the pressure vessel to remove fine particles with a turbidity of 1 degree or more to meet the requirements of the subsequent process on the water; sometimes it is also installed at the end of the entire water treatment system to prevent small Fine particles (such as broken resin) enter the finished product.
Structure and principle
The security filter adopts the formed filter material. Under the action of pressure, the raw liquid passes through the filter material, and the filter residue is left on the pipe wall. The filtrate passes through the filter material to achieve the purpose of filtering. Structure: filter cloth, filter, filter, sintered filter, wire wound filter, melt blown filter, etc. Due to the different filter materials, the filter pore size is not the same. Precision filtration is a filtration between sand filtration (raw filtration) and ultrafiltration. The filtration pore size is generally in the range of 0.5-120 μm. The same type of filter material can be divided into different specifications according to the shape size. Wirewound filter (also known as honeycomb filter) There are two: one is polypropylene fiber - polypropylene skeleton filter, the maximum use temperature of 60 °C; the other is cotton fiber - stainless steel skeleton filter, the maximum temperature of 120 °C. The meltblown filter element is a filter material formed from polypropylene as a raw material and a melt blown process. The maximum working temperature is 60°C. Precise filtration removes suspended solids, certain colloidal substances and small particles in water.
component
The security filter is mainly composed of a filter housing, a filter element, etc. Most of the filter housing is composed of R304 stainless steel material. For example, it can be used for special occasions such as acid and alkali, and R316 stainless steel can be used as a housing. Can be divided into flange type and clamp type, while the flange type housing is mainly used in the occasion with large filtering flow. The filter cartridge installed in the middle of the filter housing is mainly made of PP filter cotton core. In some occasions, wire wound filter elements or activated carbon filter elements can also be used. The number of filters installed can range from one to a few dozen, mainly based on the amount of processing to determine
