What is a small security filter? You will know after reading
The small security filter is also called precision filter, which can protect the water treatment system. It can not only filter the raw water, but also automatically clean and discharge sewage. It can also provide uninterrupted water supply while cleaning. In addition, the traditional filter has a lot of inconveniences such as small amount of pollution, easy to be blocked by dirt during filtering, and the filtering part requires manual disassembly and cleaning, etc., and it can easily achieve extraordinary projects with low cost. It is a filter element for removing impurities in industrial water treatment, and is widely used in water treatment for power plant industry.
The small security filter is a process in which one or more filter media is used to pass highly turbid water through a granular or non-granular material with a certain thickness under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Its function is to remove various impurities in the oil, so as not to scratch, wear, or even jam parts with relative movement, or block small hole gaps on parts, affecting the normal operation of the system and reducing the life of the hydraulic components. It may even cause failure of the hydraulic system. It is very important to filter the oil with a filter.
The small security filter uses a formed filter material. The original liquid passes through the filter material, and the filter residue remains on the wall of the filter material. The filtrate flows out through the filter material to achieve the purpose of filtration. The filter materials for small security filters are: filter cloth, filter screen, filter sheet, sintered filter tube, wire wound filter element, melt blown filter element, microporous filter element and multi-function filter element. Due to different filter media, the filter pore size is also different. Precision filtration is a filter between sand filtration (coarse filtration) and ultrafiltration. The filtration pore size is generally in the range of 0.1-120 μm. The same form of filter material is divided into different specifications according to the overall size. There are two types of wire-wound filter elements (also known as honeycomb filter elements): one is a polypropylene fiber-polypropylene frame filter, which can be used at a temperature of 60 ° C; the other is an absorbent cotton fiber-stainless steel frame filter, which can be used at a temperature of 120 ° C. The shell of the cylinder is generally made of stainless steel. The interior uses tubular filter elements such as PP meltblown, wire burning, folding, titanium filter elements, and activated carbon filter elements as filter elements. Different filter elements are selected according to different filter media and design processes to achieve the effluent quality. Requirements. The body can also be equipped with a quick installation type for quick and easy replacement of the filter element and cleaning. Small security filters are widely used in pharmaceutical, chemical, food, beverage, water treatment, brewing, petroleum, printing and dyeing, environmental protection and other industries. They are ideal equipment for filtering, clarifying and purifying various liquids.
