Use method of filtering membrane assembly

Abstract

The invention belongs to the field of filtration, and particularly relates to a use method of a filtering membrane assembly. A filtering device comprises a machine body, the bottom of the machine body is fixedly connected with a water outlet pipe, the upper surface of the machine body is fixedly connected with an outer cover, the upper surface of the outer cover is fixedly connected with a water inlet pipe, and the lower surface of the outer cover is fixedly connected with a main blow-off pipe. According to the use method of the filtering membrane assembly, by arranging a centrifugal mechanism, when fluid filtered by a standing mechanism and an adjusting mechanism flows to the centrifugal mechanism from a sieve plate, a turbine drives a roller to rotate under the action of fluid impact force, and the fluid flows out from a through hole in the top of the roller under the influence of centrifugal force; and settled impurities flow into the bottom cover from the through hole in the bottom of the roller and are finally discharged from an auxiliary blow-off pipe, and the fluid subjected to multi-stage filtration finally flows out of a water outlet pipe under the adsorption filtration action of a multilayer plate and activated carbon, so that the problems of single-stage filtration and poor filtration effect of traditional filtration equipment are solved.

Description

technical field [0001] The invention belongs to the field of filtration, in particular to a method for using a filtration membrane module. Background technique [0002] The full name of the filter membrane is a microporous filter membrane, which is used in raw materials, pharmaceutical solvents, water for injection, and injections, including mixed fiber microporous filter membranes, etc. The filter membranes are classified according to the size of the intercepted raw water particles. Microfiltration membrane (MF), ultrafiltration membrane (UF), nanofiltration membrane (NF) and reverse osmosis membrane (RO). [0003] Because the traditional filtration membrane module adopts single-stage filtration method, and the fluid flow cannot be precisely controlled during the filtration process, it is easy to cause impurities to block the inside of the equipment, thereby reducing the filtration effect.
