Tubular membrane module for water treatment

Abstract

The application relates to the technical field of water treatment, in particular to a novel tubular membrane module for water treatment. The tubular membrane module comprises a plurality of tubular membrane elements. After the tubular membrane membrane tubes are laid flat, the tubular membrane elements are clamped by a clamp and then sealed by pouring glue in the cavity of the clamp. Compared with the traditional tubular membrane element in a cylindrical shape, the tubular membrane module solves the problem of low artificial efficiency in manufacturing rectangular elements by using tubular membranes. The two or more pieces of prepared tubular membrane flat elements are assembled in parallel by using the grooves on the water collecting shell, and the tubular membrane module is manufactured, the filling density is increased, and the large-scale application is realized.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment, and particularly relates to a novel tubular membrane module for water treatment. BACKGROUND

[0002] Membrane separation technology is a new technology that uses separation membranes as the core to separate, concentrate and purify substances. There are four types of membrane separation technology in terms of structure, namely flat membrane, tubular membrane, spiral membrane and hollow fiber membrane. Tubular membrane has a unique structure, a large tube diameter and strong pressure resistance, and can be used for high-pressure backwashing, so it is widely used in internal pressure cross-flow filtration scenarios. However, this method has high energy consumption, and is currently only used for some high-difficulty wastewater treatment. The mature submerged module on the market is mainly based on hollow fiber membrane, which is soft and thin, and cannot be widely applied.

[0003] In view of the above technical problems, the technical personnel in the field have also researched various tubular membrane modules. For example, the utility model patent CN216572477U discloses a tubular membrane module and a tubular membrane filtration system, which adopts a clamp structure to radially lock adjacent tubular membranes and connecting pipes, is simple to operate, and allows a certain fitting error on the butt joint surface. However, its operation cost is high. The invention patent CN111214960A discloses a tubular membrane module, which sets the tubular membrane structure to include a tubular membrane element and a head and a tubular connecting piece connected to the tubular membrane element, and sets a sealing glue at the joint seam. The outer wall of the connection between the tubular membrane element and the head and the tubular connecting piece is formed with a sealing layer by spraying / painting and baking process, so as to realize the sealing connection of the tubular membrane element and the head and the tubular connecting piece. However, its manufacturing cost is high.

[0004] The present application provides a novel tubular membrane module for water treatment, which reduces the manufacturing cost, saves labor, can be widely applied to MBR process scenarios, and can realize high-pressure backwashing, having unique advantages. SUMMARY
