【発明の詳細な説明】 （産業上の利用分野） 本発明は液体を処理する処理装置に組み込まれた内圧型
中空糸型モジュールの無菌リーク検出方法に関するもの
である。Description: TECHNICAL FIELD The present invention relates to a method for detecting aseptic leak of an internal pressure type hollow fiber type module incorporated in a treatment device for treating a liquid.
（従来技術） 中空糸型モジュールは工業用液体の処理，医療用水の製
造、超純水の製造等に広く使用されている。(Prior Art) Hollow fiber modules are widely used for treating industrial liquids, producing medical water, producing ultrapure water, and the like.
中空糸型モジュールのリーク検出に関しては、従来から
種々の方法が提供されている。たとえば、特開昭５５−
７０２５８では、中空糸外側から気体を圧入し、中空糸
内側の中空糸端末へ出てくる気柱によりリーク場所を個
々に検出する方法が述べられている。しかし、これらは
中空糸型モジュールが単独の状態に於いてである。Various methods have been conventionally provided for leak detection of hollow fiber modules. For example, JP-A-55-
70258 describes a method in which a gas is press-fitted from the outside of the hollow fiber and the leak location is individually detected by an air column coming out to the end of the hollow fiber inside the hollow fiber. However, these are in the state where the hollow fiber type module is alone.
液体処理装置に組み込まれた中空糸型モジュールが使用
によりリークするようになった場合、リークの発生が他
の手段たとえば処理した液の品質低下等により検出され
て、これによりモジュールを装置から取り外して検査す
るまでは、モジュールのリークかどうかわからない。When the hollow fiber type module incorporated in the liquid processing device leaks due to use, the occurrence of the leak is detected by other means, for example, deterioration of the quality of the processed liquid, so that the module can be removed from the device. I don't know if it is a module leak until I inspect it.
処理した液の品質の低下によって、モジュールのリーク
を検出するのでは、処理液が無駄になるし、品質低下の
小さい場合には長期に渡り低品質のものを生産すること
になる。If the leak of the module is detected due to the deterioration of the quality of the processed liquid, the processing liquid is wasted, and if the quality deterioration is small, a low quality product is produced for a long period of time.
このように使用中に、中空糸型モジュールがリークして
も、その検出手段がないことは大問題である。Even if the hollow fiber type module leaks during use as described above, there is a big problem that there is no means for detecting the leak.
この様な状況に鑑み、本発明者らは鋭意検討した結果、
本発明を完成させた。In view of such a situation, as a result of intensive investigations by the present inventors,
The present invention has been completed.

中空糸型モジュールの無菌リーク検出方法である。(Structure of Invention) That is, in the present invention, a means for supplying aseptic air is provided to a pipe communicating with a hollow fiber outer space of a module in a hollow fiber type module incorporated in a treatment device for treating a relatively clear liquid. At the same time, a transparent cap is provided on the module end to release the pressure inside the hollow fiber and to send sterile air to the outside of the hollow fiber when the liquid is not being processed. A method for aseptic leak detection of a hollow fiber type module, which is characterized by maintaining a high state and detecting air bubbles leaking from an end of a leaky hollow fiber through a transparent cap.

る。The point of the present invention is to make the cap portion of the hollow fiber type module transparent so that the end portion of the hollow fiber can be seen from the outside through the cap and the treatment liquid in a state where the end portion of the hollow fiber is attached to the treatment device. Sending sterile air from the outside of the hollow fiber, without contaminating the outside of the hollow fiber with bacteria,
The air can be seen as small bubbles in the treatment liquid from the hollow fiber end corresponding to the leaked hollow fiber, and the leak can be directly detected. This operation can be reliably performed within 3 minutes after stopping the operation of the device. Therefore, by performing this operation frequently (for example, once an hour), the module can be replaced immediately when the hollow fiber leaks. It is possible to significantly reduce the generation amount of the treatment liquid of which the quality is deteriorated.
