Hollow fiber membrane module and puller used therefor

Abstract

A hollow fiber membrane module (200) and a puller (300) used therefore is disclosed, wherein each individual hollow fiber membrane module can be easily pulled out from a filtering apparatus provided with a plurality of hollow fiber membrane modules if it is required to be replaced or repaired. At this time, the hollow fiber membrane module (200) comprises a hollow fiber membrane (220); and at least on header (210) to which the hollow fiber membrane is potted, wherein the header (210) includes a first lateral side to which the hollow fiber membrane is potted and a second lateral side opposite to the first lateral side; and wherein an engaging plate (213) is formed at the second lateral side. Also, the puller (300) comprises a main body (310) and a hooking member (320), extending from an end of the main body, formed in a shape suitable for being caught in the engaging plate (213).

Description

TECHNICAL FIELD[0001]The present invention relates to a hollow fiber membrane module and a puller used therefor, and more particularly, to a hollow fiber membrane module and a puller used therefor, wherein each individual hollow fiber membrane module can be easily pulled out from a filtering apparatus provided with a plurality of hollow fiber membrane modules if it is required to be replaced or repaired.BACKGROUND ART[0002]A separation method using a membrane has lots of advantages over the method based on heating or phase-changing. Among the advantages is high reliability of water treatment since the water purity required can be easily and stably satisfied by adjusting the size of the pores of a membrane. Furthermore, since the separation method using a membrane does not require a heating process, a membrane can be used with microorganism which is useful for separation process but may be adversely affected by heat.[0003]Among the membrane employing separation methods is a method us...

AI Technical Summary

Benefits of technology

[0026]A hollow fiber membrane module according to the present invention and a puller used therefor has the following advantages.

[0027]Each individual hollow fiber membrane module can be easily pulled out from a filtering apparatus provided with a plurality of hollow fiber membrane modules if it is required to be replaced or repaired. In this case, even though the plurality of hollow fiber membrane modules are maintained in close contact with one another, the individual hollow fiber membrane module to be replaced or repaired can be easily pulled out from the filtering apparatus without disassembling the filtering apparatus.

Problems solved by technology

Furthermore, since the separation method using a membrane does not require a heating process, a membrane can be used with microorganism which is useful for separation process but may be adversely affected by heat.

However, when the submerged-type hollow fiber membrane module is used to treat wastewater, the solids in the wastewater fouls the membranes causing their permeability to be declined as the water treatment is processed.

Furthermore, there is a high possibility that the hollow fiber membrane modules 100a, 100b, 100c, and 100d are damaged by their collision.

Furthermore, a large-sized hollow fiber membrane module according to a recent trend requiring a large water-treatment capacity may cause more difficulty in individually pulling out each individual hollow fiber membrane module from the filtering apparatus.
