Description
【特許請求の範囲】
【請求項１】 複数の中空糸膜がポッティング材により固定された中空糸膜モジュールであって、複数の中空糸膜が拘束部材にて収束された固定部分を有し、かつ該固定部分と、その近傍における中空糸膜の非固定部分とにわたる領域において、該固定部分と該非固定部分の外表面に可撓性部材層を有することを特徴とする中空糸膜モジュール。
【請求項２】 該可撓性部材は、一液硬化型ウレタン樹脂からなることを特徴とする、請求項１記載の中空糸膜モジュール。
[Claims]
1. A plurality of hollow fiber membranes is a hollow fiber membrane module which is fixed by a potting material, having a fixed part in which a plurality of hollow fiber membranes is converged by the restraining member, and with said fixed portion, in the region over the non-fixed portions of the hollow fiber membranes in the vicinity of the hollow fiber membrane module characterized by having a flexible member layer on the outer surface of the fixed portion and the non-fixed portion.
2. The hollow fiber membrane module according to claim 1, wherein the flexible member is made of a one-component curable urethane resin.

TECHNICAL FIELD OF THE INVENTION
The present invention, purification of drinking water well water, tap water, domestic wastewater and industrial wastewater purification under drainage etc., used in the solid-liquid separation in an industrial process or the like, it relates to a medium Soraitomaku module.
すなわち、本発明の要旨は、複数の中空糸膜がポッティング材により固定された中空糸膜モジュールであって、複数の中空糸膜が拘束部材にて収束された固定部分を有し、かつ該固定部分と、その近傍における中空糸膜の非固定部分とにわたる領域において、該固定部分と該非固定部分の外表面に可撓性部材層を有することを特徴とする中空糸膜モジュールにある。
これにより、座屈応力の集中を緩和するのみならず、中空糸膜の固定部分近傍での膜間への異物の侵入を防ぎ、中空糸膜が損傷することを確実に防止できる。
That is, the gist of the present invention is a hollow fiber membrane module in which a plurality of hollow fiber membranes is fixed by a potting material, having a fixed part in which a plurality of hollow fiber membranes is converged by the restraining member, and the fixed and partial, in the region extending a non-fixed portion of the hollow fiber membranes in the vicinity, in the hollow fiber membrane module characterized by having a flexible member layer on the outer surface of the fixed portion and the non-fixed portion.
This not only reduces the concentration of buckling stress but also prevents foreign matter from entering between the membranes in the vicinity of the fixed portion of the hollow fiber membrane, thereby reliably preventing the hollow fiber membrane from being damaged.
