&Flange type security filter medium flow flange opening security filter
(1) Introduction
The security filter (precision filter) is an essential filtration unit in the water purification system and is an intermediate A filtration device between sand filtration (coarse filtration) and ultrafiltration, providing a water source that meets the requirements for subsequent ultrafiltration filters. The small and medium flow flange opening security filter produced by our company has a variety of specifications, a variety of filter materials, covering a variety of filtration precision. The structure of this product consists of upper and lower layers, including a mixed flow layer and a purification layer, which separates Water before and after purification to keep water safe for subsequent ultrafiltration filters. This equipment has a wide range of applications. It is most commonly used for security filtration before ultrafiltration, reverse osmosis, ion exchange, and electrodialysis. It can also be used as an ideal equipment for various liquid purification treatments.
(2) Performance characteristics
The casing is all made of stainless steel, and the surface treatment is mirror electrolytic polishing or matt, which is durable and does not rust.
The medium inlet and outlet can be connected in various ways according to the use environment, such as side in and side out, side in and bottom out, etc. Standard flanges or threaded mouths can be used.
The machine body adopts flange connection, and the ring head quick-opening bolt opens. It has high strength, good sealing performance, and is convenient to open and maintain the equipment.
. The inlet and outlet are connected by threaded connections, flanges, etc., which are available for customers to choose from.
The shell is equipped with a sewage outlet, which can remove precipitated pollutants in a timely manner.
. The upper end of the casing is equipped with an exhaust port to reduce the air pressure in the equipment in a timely manner.
. The bottom of the equipment body can be equipped with anchor bolt holes and can be fixed on the ground.
. According to different filtration requirements, melt-blown filter elements, wire-wound filter elements, microporous pleated filter elements, etc. can be selected.
(3) Working principle
The security filter uses shaped filter material. Under the action of pressure, the original liquid passes through the filter material, the filter residue is retained on the pipe wall, and the filtrate flows out through the filter material, thereby achieving For the purpose of filtration, the formed filter materials include: filter cloth, filter screen, sintered tube, etc. Due to different filter materials, the filter pore sizes are also different. Precision filters are between sand filtration (coarse filtration) and ultrafiltration. This kind of filtration, the filter pore size is generally in the range of .~&. The same type of filter material can be divided into different specifications according to the external dimensions. There are two types of wire-wound filter elements (honeycomb filter elements): one is polypropylene fiber and polypropylene skeleton, with a maximum operating temperature of ℃; the other is absorbent cotton fiber and stainless steel skeleton, with a maximum operating temperature of ℃. The melt-blown filter element is made of polypropylene as the raw material. The filter material formed by the Ayong melt-blown process has a maximum working temperature of ℃. The security filter can remove suspended solids, certain colloidal substances and small particles in the water
