product description

Multi-column automatic backflush filters provide fully automatic, backflush cleaning operations and can continuously separate impurities from water and other liquids. Filters are easy to service and operate, and continue to perform well even under harsh operating conditions. Multi-column automatic backwash filters can be equipped with different numbers of filter elements in each filter to provide a relatively large filter area. This allows the filter to have as little pressure loss as possible when in use. The pressure design of the main part of the filter is usually based on the standard design of chemical pipeline filters and steel pressure vessels. Filters can also be adapted to special requirements of other design criteria. The main part of the equipment is made of carbon steel, stainless steel, duplex steel and other materials. At the same time, we can also provide you with special materials such as titanium and pure nickel.

working principle

Water enters from the inlet, and during the filtration process, the fine filter mesh gradually accumulates dirt and impurities in the water to form a filter impurity layer. Since the impurity layer accumulates on the inside of the fine strainer, a pressure difference is formed between the inside and outside of the fine strainer. When the pressure difference of the filter reaches the preset value, automatic cleaning starts. During this period, the clean water supply is continuous, the cleaning valve is opened, the water pressure in the cleaning room and the sewage suction device drops significantly, and the pressure difference between the filter cartridge and the sewage suction pipe passes through, and a suction force is generated between the sewage suction pipe and the cleaning room through the suction nozzle. Form a suction process. At the same time, the electric motor drives the sewage suction pipe to make a spiral movement in the axial direction, and the combination of the axial movement and the rotary movement of the sewage suction device completely cleans the inner surface of the entire filter screen, and the entire flushing process only takes tens of seconds. The blowdown valve is closed at the end of the cleaning and the filter is ready for the next flushing cycle.
