Problems solved by technology

However, due to the long solidification time of the adhesive (1 to 2 hours), the glue filling process is also slow, so the production efficiency is low; moreover, when cutting the head at the end, because the cured adhesive is hard, cutting is difficult, also lower production efficiency
A large amount of adhesives and resins are used in the manufacturing process of the membrane module, and the cost is high

Embodiment Construction

[0027] In general, the manufacturing method of the hollow fiber separation membrane module according to the present invention comprises the following steps:

[0028] A plurality of hollow fiber separation membrane filaments are composed of membrane bundles, and the membrane pores at both ends of the membrane filaments are blocked with gypsum powder.

[0029] packing the membrane bundle into the housing of the hollow fiber separation membrane module;

[0030] Potting both ends of the membrane bundle with a sealant to form a sealed end;

[0031] Both ends of the membrane bundle body are cut to make the membrane holes of the hollow fiber membranes conduct.

[0032] According to an embodiment of the present invention, the method also includes the following steps:

[0033] Before the two ends of the membrane bundle are potted with sealant, the membrane filaments are pre-fixed with gypsum.

[0034] Wherein, using gypsum powder to block the membrane pores at both ends of the membr...

Abstract

The invention discloses a making method of a hollow fiber separating membrane assembly, and a made hollow fiber separating membrane assembly. The making method comprises the steps of enabling membrane silks of a plurality of hollow fiber separating membranes to form a membrane beam body, plugging membrane silk holes in two ends of each membrane silk by using gypsum powder; loading the membrane beam body into a shell of the hollow fiber separating membrane assembly; encapsulating two ends of the membrane beam body by using sealant to form a sealing end; cropping two ends of the membrane beam body to ensure that the membrane silk holes of the hollow fiber membrane are communicated. The making method provided by the invention is lower in cost, simple to operate and high in production efficiency.

Description

technical field [0001] The invention relates to membrane separation technology, in particular to a manufacturing method of a hollow fiber separation membrane module. Background technique [0002] Membrane separation technology is a technology that uses separation membranes to separate, concentrate and purify solutions or gaseous substances. The membrane wall of the separation membrane is densely covered with micropores. The raw liquid passes through one side of the membrane under a certain pressure, and the solvent and small molecular solute pass through the membrane wall to become the filtrate, while the macromolecular solute is retained by the membrane to achieve the purpose of material separation and concentration. Compared with other gas separation methods, the gas separation method using a membrane has high energy efficiency and simple device structure, so it is used for the separation of various gases. [0003] The most common form of a gas separation membrane is a th...
