Filter by part of the housing, multi-filter backwash agencies, and differential pressure controllers and other components. Transverse bulkhead within the housing cavity into which the upper and lower chambers, the upper chamber is equipped with multiple filters, so full of filtration space, significantly reducing the volume of the filter filters installed at the cavity Backwash sucker. Work, turbid fluid through the inlet into the filter chamber under water filters, and filter through the bulkhead hole into the cavity. The gap is larger than the filter element impurities are trapped, net fluid through the gap to reach the upper chamber, and finally discharged from the outlet. Filter made of high strength wedge filter hospital sewage filter, through pressure control, timing control automatic cleaning filter. When the filter surface impurities accumulate in the filter pressure drop caused by increases to the set value, or the timer reaches the preset time, the electric control box sends a signal to drive the backwash mechanism. When the filter backwash sucked Handicap and imports are on, the drain valve opens, and the system pressure relief drainage, medial sucker with the emergence of a relative pressure below the filter cartridge outside of the pressure of the negative pressure zone, forcing part of the circulating water from the outside of the filter net flows into the inside of the filter, the filter is adsorbed on the inner wall of the contaminant particles with the water intake valve and discharged from the sewage Rang disc. Specially designed filter makes the filter internally generated jet effect, any impurities will be washed away from the smooth inner wall. When the filter pressure drop back to normal or timer set time ends, the whole process, the material continues to flow, backwash water consumption, to achieve a continuous, automated production. Filters are widely used in metallurgy, chemical, petroleum, paper, pharmaceutical, food, mining, electricity, urban water supply areas. Regeneration, such as industrial waste, recycling water filtration, emulsion, oil filter processing, metallurgical industry, casting water systems, blast furnace water system, hot-rolled with high-pressure water descaling systems. Is an advanced, efficient and easy to operate automatic filter. Shanxi Runtong Environmental Engineering Limited was founded in 2005 anti-filter, is a professional sewage treatment, waste gas treatment, dust handling and other types of environmental projects and research and design of high-tech enterprises. Chinese Ancient filtering technology already applied in production, 200 BC has been made of plant fiber paper. 105 AD Cai Lun improved the paper making process. He will plant fiber pulp papermaking process in dense fine finishes on bamboo. Water filtered through bamboo slits, a thin layer of wet bamboo pulp left in the face, dry Serve paper. The first filter mostly gravity filtration, then pressurized filtration improves filtration rate, which in turn appeared vacuum filtration. Early 20th century invention of vacuum drum filters to achieve a continuous filtration operation. Since then, various types of continuous filter has emerged. Filter intermittent operation (such as plate and frame filter press, etc.) because it can be developed to automate operations, filtration area is growing. In order to obtain a low moisture content of the filter cake, the mechanical compression of the filter have been developed. Industrial filters, filter Luliang, Shanxi Runtong environmental protection provided by the Run-Environmental Engineering Limited. Run-Environmental Engineering Co., Ltd., Shanxi (www.sxruntong.com) strong, credible, in Taiyuan, Shanxi sewage treatment equipment industry has accumulated a large number of loyal customers. The company better work attitude and continuous improvement through innovative ideas will lead Run into the brilliant green and you work for a better future!
