本発明はろ過装置に係り、特に中空糸膜をフィルタエレ
メントとして用いた中空糸膜ろ過装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filtration device, and particularly to a hollow fiber membrane filtration device using a hollow fiber membrane as a filter element.
（従来の技術〕
沸騰水型原子力発電フラントにおいては、−次系冷却水
を原子炉により沸騰させて蒸気を作り、この蒸気により
発電機に直結されたタービンを駆動した後、復水器にて
凝縮した後原子炉に戻すサイクルが構成されている。(Prior art) In a boiling water type nuclear power generation plant, sub-system cooling water is boiled in a nuclear reactor to create steam, and this steam drives a turbine directly connected to a generator, and then is sent to a condenser. The cycle consists of condensing and then returning it to the reactor.

おいては復水浄化系を設置して復水中の不純物を除去し
、不純物の原子炉への持ち込みを抑えている。If impurities are contained in this sub-system cooling water, there is a concern that these impurities will be activated by irradiation with neutron beams generated in conjunction with nuclear fission reactions in the nuclear reactor, so the above plants have installed a condensate purification system. This removes impurities from the condensate and prevents them from entering the reactor.

末状イオン交換樹脂が放射性廃棄物となっていた。In this condensate purification system, a filter element in which a powdered ion exchange resin is pre-coated has been used as a condensate filtration device for removing insoluble impurities in the condensate. However, in this precoat type filtration device, as a result of periodic backwashing and re-precoating, the powdered ion exchange resin, which is the precoat material removed by backwashing, becomes radioactive waste.
このような欠点を解決する復水ろ過装置として。As a condensate filtration device that solves these drawbacks.

にあけた穴に接続していた。このため。There is a filtration device that uses a hollow fiber polymer membrane as a filter element (see JP-A-60-61089).
This method uses a hollow fiber membrane with an outer diameter of about 1/10 to 2:11 to filter the condensate by flowing the condensate from the outside to the inside of the membrane. is taken out from the open end of the hollow fiber membrane. In such a condensate filtration device, a bundle of multiple hollow fiber membranes is bent into a U-shape and the open ends are aligned in the same direction, or one end of a bundle of multiple straight hollow fiber membranes is bent into a U-shape. A module is one in which the module is closed and only one end is open, and each open end of the plurality of modules is connected to a hole drilled in a partition plate that separates the inlet and outlet sides of the filtration device container. For this reason.
中空部を流れる水の圧力損失により開放端より遠ざかる
部位はど膜断面を通過する水の線流速（ＬＶ）が減少し
、ろ過流量が減少していた（第８図参照）。Due to the pressure loss of the water flowing through the hollow portion, the linear flow velocity (LV) of water passing through the cross section of the membrane decreased at the portion farther away from the open end, and the filtration flow rate decreased (see FIG. 8).

れている（特開昭６０−２０６４０５号）。In order to improve the timeliness of this filtration, a bundle of multiple linear hollow fiber membranes with both ends open and a water conduit pipe connecting both open ends installed in the center of the bundle is called a module. It is known that the water flowing out from the open end is guided to this water conduit pipe, and the other open end is connected to a partition plate that partitions the inside of the filtration device container between the inlet side and the outlet side. (Unexamined Japanese Patent Publication No. 60-206405).

時に発生する放射性廃棄物量の増大およびフィルタモジ
ュールコストの増大等の問題があった。The conventional device described in JP-A No. 60-206405 has a water conduit installed in the center of the hollow fiber membrane assembly as a filter module, and consideration has been given to downsizing and simplifying the structure of the module. This has led to problems such as an increase in the size of the filtration device, an increase in the amount of radioactive waste generated when replacing the filter module, which is a consumable item, and an increase in the cost of the filter module.

取出されたフィルタモジュールは放射性廃棄物となる。First, in the above filter module, the water pipe is installed in the center of the module, so the thickness of one module is correspondingly thicker. It is necessary to treat the condensate, and for this purpose it is necessary to use multiple filter modules. However, when installing filter modules in the container of a filtration device, each filter module must be installed at intervals of a certain distance or more.
Since the filter element is large in thickness, there is a drawback that the size of the filtration device must be increased. Furthermore, although the design life of an atomic couplant is about 40 years, it is expected that the filter element module will need to be replaced every two to three years as a consumable item. The filter module removed during this exchange becomes radioactive waste.
したがって、フィルタモジュールが太いぶんだけ廃棄物
のかさが増大し、また導水管のぶん廃棄物の量が増大し
た。さらに、モジュールの中央部に導水管を配したこと
によりモジュール製作時のコストが大であった。Therefore, the bulk of the waste increases as the filter module becomes thicker, and the amount of waste increases as the water conduit becomes larger. Furthermore, the cost of manufacturing the module was high because the water pipe was placed in the center of the module.
本発明の目的は、フィルタモジュールの増大化。An object of the present invention is to increase the number of filter modules.
構造の複雑化を伴うことなく、ろ適時の圧力損失を低減

徴とするものである。In addition, in the second invention of the present application, the inside of the container is formed into two compartments by one partition plate, and a plurality of hollow fiber membranes are bundled in parallel with a space between each other with both ends open. One end of the filter element is fixed to the partition plate in communication with one end of the water conduit pipe to one of the compartments of the container, and the other end of the filter element is integrated with the other end of the water conduit pipe in communication with the partition plate. , the water to be filtered is supplied to the other compartment where the filter element is located, and the filtered water is discharged from one compartment.

Flows to each end. The fluid that flows to the end connected to the partition plate flows out of the device from the outlet side chamber, and the fluid that flows to the other end flows from the water conduit pipe to the outlet side chamber and then flows out of the device. .

達成される。Therefore, the filtration part of the hollow fiber membrane that is the furthest away from the open end of the hollow part is located in the center of the module, and the distance is half that of a filter module with one end closed, improving the timeliness of filtration. Furthermore, the filter module is made by bundling only hollow fiber membranes, so that the module can be made smaller and simpler.

The curve indicated by symbol A is for a filtration device using a conventional filter module with the lower end closed, and the curve indicated by symbol B is for a filtration device according to the present invention.1 In the case of the present invention, The linear flux LV of water at each height is larger than that of the conventional one, and this is especially noticeable at lower heights. This indicates that the present invention provides a larger filtration amount. FIG. 9 shows the relationship between the pressure loss filtration differential pressure due to filtration of the filtration device and the linear flux LV of water averaged over the entire filtration device. The curved line shown by symbol C is a filtration device using a conventional filter module with its lower end closed.
