A special multi-effect filter element for filtering solid and liquid impurities

Abstract

The invention discloses a multiple-effect filter core special for filtering solid-liquid impurities. The filter core is prepared by arranging a filter layer between an inner pipe and an outer pipe, and performing thermofusion welding on two end covers with the inner pipe, the outer pipe and the filter layer. The innovation points comprise that the filter layer is prepared by combining a solid-state-impurity filter layer and a liquid-state-impurity filter layer; combination employs diversified manner, so as to facilitate the product to adapt to diversified filtering demands; solid-liquid integrated filtering design is employed, so that the multiple-effect filter core is capable of adapting to requirements on filtering of multiple impurities, and reaching the purposes of high filtering efficiency, multiple filtering manners, wide filtering types and good filtering effect.

Description

technical field [0001] The invention relates to a special filter element for filtering resources, in particular to a special filter element for filtering solid impurities and liquid impurities. Background technique [0002] Microfiltration membranes account for more than 50% of the entire membrane market share in the United States, Japan, and Europe. They are widely used in the separation and purification of fluids, wastewater filtration and recovery of useful components, zero discharge of industrial wastewater, and activated sludge membrane process waste (sewage) water Treatment reuse (membrane bioreactor, MBR), etc. It is mainly used for drinking water treatment in foreign countries, and it is mainly used for wastewater treatment and reuse in industrial fields in China. In addition, as a pretreatment of reverse osmosis, it has also been widely recognized. For example, the combined microfiltration / reverse osmosis double-membrane technology is widely used in domestic indust...
