詰り物質を溶解させる薬品洗浄を実施する場合もある。[Prior art and problems to be solved by the invention] In a hollow fiber tubular filtration membrane filter device that uses a large number of hollow fiber tubular membranes to filter and remove fine solids from industrial wastewater, each hollow Tube-shaped filtration membranes are used by filling them vertically in a filtration tower as hollow fiber modules.
This includes an external pressure type in which liquid is passed from the outside to the inside of the hollow fiber tubular filtration membrane, and an internal pressure type in which liquid is passed from the inside to the outside of the filtration membrane. In this hollow fiber tubular filtration membrane filter device, fine solids in wastewater are removed by the membrane through filtration, and as a result of the removal, filtration resistance occurs and the differential pressure of the filter reaches an upper limit. If the differential pressure has increased, the filter usually stops water flow, is cleaned with water or air, and is reused, but sometimes chemicals are used to dissolve the deposits or clogging substances on the membrane. Chemical cleaning may also be performed.

特別に管理された固体廃棄物処理設備で廃棄処分が行な
われる。In particular, hollow fiber modules used to treat industrial wastewater within nuclear power plants are contaminated with radioactive materials and cannot be disposed of as general industrial waste, but are treated as solid waste that is specially managed within the power plant. The waste is disposed of in a treatment facility.
原子力発電所内で中空糸モジュールを廃棄処分する場合
には、廃棄物用ドラム缶に充填し保管するか、可燃性の
材料の場合焼却炉で焼却処分するかの何れかが選択され
る。When disposing of hollow fiber modules within a nuclear power plant, the choice is to either fill and store them in waste drums, or in the case of flammable materials, incinerate them in an incinerator.

リエチレン等のプラスチック袋に入れる必要がある。The hollow fiber module used generally has a thickness of 8011/Ill to 160m/Ill and a length of approximately 1T.
It is of rL~2m. Compared to the size of this hollow fiber module, the waste drum used in nuclear power plants has dimensions of 567°φX830'H (JIS 1
1600 H type), it is not possible to directly put the hollow fiber modules in and store them for disposal, so it is necessary to cut the hollow fiber modules into pieces that can be filled into drums. Furthermore, when incinerating in an incinerator, there are restrictions on the size and weight of the incinerated material due to the capacity and size of the incinerator, and domestic power plants generally have dimensions of 301 or less and weights of 2 to 3! j/pieces. Furthermore, for handling purposes, it is necessary to put the incinerated materials into plastic bags such as polyethylene when putting them into the incinerator.

行う必要がある。Hollow fiber modules used in condensate purification equipment at nuclear power plants have a purification capacity of 3,000 to 7,000
Since the size is as large as 00 butts/H, the number of bundles used is large, ranging from several hundred to several thousand bundles. For this reason, it is necessary to safely and reliably cut and dispose of the used hollow fiber modules that are generated as a result of updating the hollow fiber modules, and also to perform the work efficiently since there are a large number of them.

る。(Means for Solving the Problems) The present invention has been made in accordance with such demands, and includes hollow fiber modules, each of which is a bundle of a large number of hollow fiber tubular filtration membranes, packed vertically into a filtration tower. From an external pressure type or internal pressure type hollow fiber tubular filtration membrane filter device that passes wastewater containing radioactive substances from the outside to the inside of the filtration membrane or from the inside to the outside of the filtration membrane, radioactive After taking out the hollow fiber module contaminated with the substance and cutting it,
In the disposal device, use a cutting device to suspend the hollow fiber module contaminated with radioactive materials taken out from the hollow fiber tubular filtration membrane filter device or its intermediate storage tank vertically, rather than horizontally. The gist is a disposal device for hollow fiber modules contaminated with radioactive materials, which is characterized by sequentially cutting from the bottom and bagging or canning each cut piece individually, thereby achieving the intended purpose. I'll go.

でより安全性の高いものとなる。The hollow fiber module disposal device of the present invention safely and reliably takes out hollow fiber modules contaminated with radioactive materials from a hollow fiber tubular filtration membrane filter device (filter), transports them, and cuts them into cut pieces of a desired length. It performs cutting and then collects the cut pieces, and is designed to make these operations efficient. Furthermore, although there are no particular restrictions on the above-mentioned cutting device, if this is carried out using a circular saw, etc., chips will be generated, and it is necessary to take measures to scatter the chips, which are radioactive waste, or to dispose of them. However, if a hydraulic cutter is used as the cutting device, this kind of treatment will be unnecessary and safety will be higher.
濾過塔内の放射性物質で汚染された中空糸モジュールは
クレーン、モノレールホイスト等のホイスト装置により
濾過塔内より吊り上げて弓き出し、これを吊り状態のま
ま直接にまたは中間貯槽に貯留してから切断装置の上方
へに搬送する。Hollow fiber modules contaminated with radioactive materials inside the filtration tower are lifted out of the filtration tower using a hoisting device such as a crane or monorail hoist, and then cut directly while suspended or stored in an intermediate storage tank before being cut. Convey to the top of the device.
中空糸モジュールは濾過塔内に垂直縦方向に多数本束状
とした状態で充填配列して使用されるため沼過塔からこ
れら中空糸モジュールを取出す場合、１束づつクレーン
あるいはモノレール等の電動ホイストにより吊上げて引
き扱く。Hollow fiber modules are used by packing and arranging them in a bundle in the vertical direction inside the filtration tower, so when removing these hollow fiber modules from the filtration tower, one bundle at a time must be taken out using a crane or an electric hoist such as a monorail. Lift it up and handle it.
そこで本発明ではこの吊上げて切断装置の上方に搬送し
た中空糸モジュールを単にホイスト装置で降下させるだ

の調整並びに移動が簡単に行なうことができるようにな
っている。その際この中空糸モジュールの保持案内装置
をホイスト装置と共働させることにより中空糸モジュー
ルの切断と下降とを円滑に順次実施することができる。Therefore, in the present invention, the hollow fiber module that has been lifted and transported above the cutting device is supported and guided by a hollow fiber module support jig or support metal fittings so that the cutting operation can be started simply by lowering the hollow fiber module using a hoist device. This makes these operations extremely efficient, and when cutting into pieces, the length of the cutting section can be adjusted and moved simply by lowering it using a hoist. At this time, by cooperating the holding and guiding device for the hollow fiber module with the hoist device, the cutting and lowering of the hollow fiber module can be carried out smoothly and sequentially.
また中空糸モジュールの下降をホイスト装置とは切り離
してこの保持案内装置のみで実施してもよい。Further, the lowering of the hollow fiber module may be separated from the hoist device and carried out only by this holding and guiding device.
またこの保持案内装置は切断の際、中空糸モジュールが
動かないようにする固定治具も兼ねている。This holding and guiding device also serves as a fixing jig to prevent the hollow fiber module from moving during cutting.
所定長さに切断された中空糸モジュールは切断とともに

バラバラの多数の切断片は散乱せしめることなく複数個

容器状のものを使用し、この中にポリエチレン袋を着脱
自在に装着しておく。切断片を入れたポリエチレン袋は
、上端を封じて捕集機から取り出し固体廃棄物として出
荷し、焼却場まで運搬する。The hollow fiber modules cut to a predetermined length are separated into bundles and fall apart as they are cut. A turntable collector equipped with a plurality of collecting pockets collects a large number of these separated cut pieces without scattering them. Most of the cut pieces are hollow fibers, and if they are scattered, handling becomes very complicated. Therefore, it is preferable to cut, drop, and catch the pieces and simultaneously store them in a plastic bag such as a polyethylene bag. For this reason, the collector uses a container-like container that can accommodate the cut pieces, and a polyethylene bag is removably attached to the container. The polyethylene bags containing the cut pieces are sealed at the top, removed from the collector, shipped as solid waste, and transported to an incineration plant.
切断−捕受一袋封じ一取出し−ボ１ノ袋装着が一連の作
業であるが、１個の捕集機では一連の作業が数分を要す

場合数十分を要することになり、効率的でなく、他の作
業に与える影響が大きい。また他作業と同時に実施する
場合、−時中空糸膜フィルタを保護する場所と設備が必
要となり不経済である。Cutting - catching one bag, sealing, taking out - loading one bag is a series of operations, but since this series of operations takes several minutes with one collection machine, the hollow fiber module is vertically moved up and down 10 times. It takes several tens of minutes to divide, which is not efficient and has a large impact on other tasks. In addition, if the process is carried out simultaneously with other operations, a place and equipment to protect the hollow fiber membrane filter are required, which is uneconomical.
このため中空糸膜フイルタ交換に関わる他の作業と切断
廃棄作業を同時併行させるのが好ましい。このため切断

数個の捕集機を回転して順次使用し、切断−捕受１袋封

のが好ましい。For this reason, it is preferable to carry out other operations related to hollow fiber membrane filter replacement and cutting and disposal operations at the same time. Therefore, it is necessary to perform the cutting work efficiently and in a short time, and for this purpose, multiple collectors are rotated and used in sequence, and cutting, catching, sealing and taking out one bag, and attaching a plastic bag can be done at the same time. It is preferable to take care to ensure that
