A submerged hollow fiber membrane module

Abstract

A hollow fiber membrane module is used for solid-liquid separation operations in water treatment or chemical, pharmaceutical and other fields. It is characterized in that it belongs to the submerged membrane module. Curtain membrane element (1), upper water collection pipe (2) and lower water collection pipe (4); the two water collection pipes are not only used as a collection channel for filtered water and a flushing channel during membrane cleaning, but also a supporting structure for the membrane module ; The curtain membrane element (1) communicates with the water collection pipes (2) and (4) through a socket interface, with a flexible sealing ring in between, and the curtain membrane element (1) is fixed on the water collection pipe by an arc clamp Above (2) and (4); the connection between the curtain membrane element (1) and the water collecting pipes (2) and (4) is a detachable structure.

Description

technical field [0001] The invention relates to a hollow fiber membrane module placed in water or other liquids, which is used for solid-liquid separation operations in water treatment, chemical, pharmaceutical and other processes, such as for concentrating cells in water, or for filtering water for use It contains no suspended solids. Background technique [0002] In the field of water treatment and chemical technology, it is often necessary to separate solid particles dispersed in water or other liquids (hereinafter referred to as suspended solids) from water or other liquids. For the convenience of description, the separation of suspended solids from water containing solid impurities is taken as an example below. When this process is achieved by passing water containing suspended solids through a porous medium, it is often referred to as filtration. Membrane separation technology is an effective method to realize this solid-liquid separation process. The operation proc...

AI Technical Summary

Problems solved by technology

At present, most of the hollow fiber membrane products on the market do not take into account the above-mentioned functional requirements, and there are one or another shortcomings, such as inconvenient disassembly, complex structure, or consumption of a large amount of stainless steel as a supporting structure, or due to poor hydraulic conditions. Poor physical cleaning process

In addition, these existing products all have a common outstanding defect, that is, a membrane element can only form a membrane module of one shape, and the membrane elements cannot be interchanged between different membrane modules, or even if they are barely Can be interchanged, the cost of replacement is also very high, and the replacement process is also very troublesome
