〔産業上の利用分野〕
本発明は、火力又は原子力発電設備等、使用済イオン交
換樹脂の発生する設備における使用済イオン交換樹脂の
移送方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for transferring used ion exchange resin in equipment where used ion exchange resin is generated, such as thermal or nuclear power generation equipment.
従来、原子力発電所で発生した使用済イオン交換樹脂は
、特公昭５Ｂ−２３６００号に記載の様に、発電所内各
発生源から一ケ所に集中的に設置された一群の貯蔵タン
クもしくは貯槽（以下貯槽と総称する）に投入され沈降
状態・で貯蔵された後、処理必要時に以下の３つの方法
のいずれかで抜き出され、処理設備に移送されていた。Traditionally, spent ion exchange resin generated at nuclear power plants is stored in a group of storage tanks or storage tanks (hereinafter referred to as "storage tanks") that are centrally installed in one place from each generation source within the power plant, as described in Japanese Patent Publication No. 5B-23600. After being put into a storage tank (generally referred to as a storage tank) and stored in a sedimented state, when processing is required, it is extracted using one of the following three methods and transported to processing equipment.
（１）貯槽に直接水中攪拌ポンプを投入し、沈降した使
用済イオン交換樹脂を攪拌し、スラリー状態とした後移
送する。(1) A submersible stirring pump is placed directly into the storage tank, and the settled used ion exchange resin is stirred to form a slurry and then transferred.
（２）貯槽中に空気を吹き込み、沈降した使用済イオン
交換樹脂をスラリー状態とした後移送する。(2) Air is blown into the storage tank to make the sedimented used ion exchange resin into a slurry state and then transported.
（３）貯槽に循環配管を設置し、エダクタ−駆動流によ
シ沈降した使用済イオン交換樹脂を攪拌し、スラリー状
態で移送する。(3) A circulation pipe is installed in the storage tank, and the used ion exchange resin that has settled due to the eductor-driven flow is stirred and transferred in a slurry state.
上記３つの方式に共通するのは、何れの方式も移送に先
立ち、沈降した使用済イオン交換樹脂を攪拌しスラリー
状態としている点である。これは、使用済イオン交換樹
脂は沈降した状態では土砂と同様の挙動を示すため、配
管を用いた移送は不可能だからである。What the above three methods have in common is that, prior to transportation, the settled used ion exchange resin is stirred to form a slurry. This is because used ion exchange resin behaves similarly to earth and sand in a settled state, so it is impossible to transport it using piping.
また、スラリー状態となった使用済イオン交換樹脂も、
容易に再び沈降するため、移送配管内で沈降に伴う閉塞
や堆積を引き起こし易く、その配管移送は以下に示す様
に厳重な管理のもとに行われている。In addition, used ion exchange resin that has become a slurry is
Since it easily settles again, it tends to cause blockage or accumulation in the transfer piping due to sedimentation, and its transfer through the piping is carried out under strict control as described below.
（１）配管内で再び沈降しない流速を確保した設計とし
ている。（通常１ｍＡ以上）
（２）配管径路の上昇、下降を極力少くし、沈降が発生
した場合に堆積量が多くなる垂直配管部を極力少くして
いる。(1) The design ensures a flow rate that does not cause sedimentation within the piping. (Usually 1 mA or more) (2) The rise and fall of the piping path is minimized, and the vertical piping portion where a large amount of sedimentation occurs when sedimentation occurs is minimized.
（３）使用済イオン交換樹脂は粒径が００５ｍである為
、配管の口径をそれに比べて充分大きくとシ機械的な閉
塞要因を取シ除いている。(3) Since the used ion exchange resin has a particle size of 0.005 m, the diameter of the pipe is sufficiently large compared to that to eliminate mechanical clogging factors.
（４）移送を停止した状態で配管内に使用済イオン交換
樹脂が残存、沈降、堆積しない様に移送完了前に配管内
に清水を流し配管内部に使用済イオン交換樹脂が残らな
い設計としている。(4) In order to prevent used ion exchange resin from remaining, settling, or accumulating inside the piping when the transfer is stopped, fresh water is poured into the piping before the transfer is completed, so that no used ion exchange resin remains inside the piping. .
（５）配管内に絞シ部を設けない様にし機械的な閉塞要
因を取シ除いている。（例えば弁は通常ポール弁を使用
し、オリフィスはペンチエリオリフィスを使用している
。）
〔発明が解決しようとする問題点〕
使用済イオン交換樹脂の配管移送については上記の５項
目の配慮が為されているが、これら配慮事項は、以下の
問題点を有している。(5) Mechanical causes of blockages are eliminated by not providing any constrictions in the piping. (For example, a Pole valve is normally used for the valve, and a pentier orifice is used for the orifice.) [Problems to be solved by the invention] The above five items should be considered when transferring the used ion exchange resin through piping. However, these considerations have the following problems.
（１）移送流速に下限があるため、移送に用いるポンプ
の動力が大きくなる。(1) Since there is a lower limit to the transfer flow rate, the power of the pump used for transfer increases.
（２）配管経路に制限項目が多く自由に経路が選定でき
ない。この項目は、例えば原子力発電所の様に使用済イ
オン交換樹脂が放射能を含有している場合、配管経路の
制約上表面線量の比較的高い移送配管を通常のエリアに
通さなければならない様な状況を引き起こす場合があり
、その場合遮蔽体の設置等余分な設備を要することにな
る。(2) There are many restrictions on piping routes, and routes cannot be selected freely. This item applies to cases where used ion exchange resin contains radioactivity, such as in a nuclear power plant, where transfer piping with a relatively high surface dose must be routed through normal areas due to piping route restrictions. In this case, extra equipment such as installing a shield will be required.
（３）使用可能な配管口径に下限があるため、小流量の
移送が必要とされる場合必要流量が確保できぬことがあ
シ、配管経路、配管長に厳しい配慮が必要となる。(3) Since there is a lower limit to the pipe diameter that can be used, if small flow rate transfer is required, the required flow rate may not be secured, and strict consideration must be given to the piping route and length.
（４）原子力発電所の場合、使用済イオン交換樹脂の移
送完了前に配管内に流す清水も放射能を有する様になる
ため、放射性廃棄物の量を増大させることになる。必要
な清水量は配管内の容積の約２倍であるので、配管長が
長い程、また移送頻度が高い程発生する放射性廃棄物の
量は増加する。(4) In the case of a nuclear power plant, the fresh water flowing into the pipes before the transfer of used ion exchange resin is completed also becomes radioactive, which increases the amount of radioactive waste. Since the required amount of fresh water is approximately twice the volume of the pipe, the longer the pipe length and the higher the frequency of transfer, the greater the amount of radioactive waste generated.
（５）配管に設置される弁、オリアイスの型式が制限さ
れるため、設備設計の自由度が減少し、またコストも割
高となる。(5) Since the types of valves and ORIICE installed in the piping are restricted, the degree of freedom in equipment design is reduced and costs are also relatively high.
上記諸問題点を解決する為には、使用済イオン交換樹脂
を沈降させない方法を採ること、すなわち、具体的には
使用済樹脂スラリーの粘度を上昇させて高粘度流体とし
て移送することが考えられるが、しかし、それは沈降の
問題そのものは回避できるにせよ、以下の問題点を有し
実用には供し得ない。In order to solve the above problems, it is possible to adopt a method that does not cause the used ion exchange resin to settle. Specifically, it is possible to increase the viscosity of the used resin slurry and transfer it as a high viscosity fluid. However, although this method can avoid the problem of sedimentation itself, it has the following problems and cannot be put to practical use.
（１）沈降を防止させる為には、１オ一ダー以上粘度を
上昇させる必要があるが、これは移送時の圧力損失を上
昇させ、ポンプの揚程を実用範囲外としてし７まう。(1) In order to prevent sedimentation, it is necessary to increase the viscosity by one order or more, but this increases the pressure loss during transfer and puts the pump head out of the practical range.
（２）粘性を上昇させる為には、高い粘度を有する有機
物の液体を用いねばならず、大量の放射性有機物廃棄物
を発生させることになる。(2) In order to increase the viscosity, it is necessary to use an organic liquid with a high viscosity, which results in the generation of a large amount of radioactive organic waste.
本発明の目的は、前記従来の移送方法で問題となった使
用済イオン交換樹脂の沈降による配管内での閉塞、堆積
防止士の配慮が必要でなく且ポンプ動力を低減できる使
用済イオン交換樹脂の配管移送方法を提供することにあ
る。It is an object of the present invention to provide a used ion exchange resin that eliminates the problem of sedimentation of used ion exchange resin causing blockage in piping, which was a problem with the conventional transfer method, and eliminates the need for the consideration of an anti-accumulation specialist and reduces pump power. The purpose of the present invention is to provide a piping transfer method.
本発明は、使用済イオン交換樹脂のスラリーを、該使用
済イ万ン交換樹脂の粒径を小径化することによって、低
流速域では粘度が大きく、高流速域では粘度が小さくな
る擬塑性流体となして配管にて移送することを小径化す
るものである。The present invention creates a slurry of used ion exchange resin by reducing the particle size of the used ion exchange resin to form a pseudoplastic fluid that has a high viscosity in a low flow rate region and a low viscosity in a high flow rate region. This allows the diameter of the pipe to be reduced.
使用済イオン交換樹脂のスラリーの樹脂粒径を小径化す

させて破砕を行い、又は破砕器に使用済イオン交換樹脂
スラリーを通過させて行うことができる。In order to reduce the resin particle size of a slurry of used ion exchange resin, it is preferable to crush the used ion exchange resin in a slurry state. To perform this crushing, the used ion exchange resin slurry is circulated many times through the circulation piping and circulation pump installed in the tank storing the used ion exchange resin, or the used ion exchange resin is crushed in a crusher. This can be done by passing a slurry through.
第２図に使用済イオン交換樹脂スラリーをスラリー状態
で破砕した場合のスラリーの粘度と流速の関係を示す。FIG. 2 shows the relationship between the viscosity of the slurry and the flow rate when the used ion exchange resin slurry is crushed in a slurry state.

オン交換樹脂スラリーの２０倍以上の粘度を示し、スラ
リーを静置しても使用済イオン交換樹脂は沈降すること
がない。As can be seen from Figure 2, the viscosity of the crushed used ion exchange resin slurry is more than 20 times that of the uncrushed used ion exchange resin slurry in the low flow rate region. Also, used ion exchange resin does not settle.
また高流速域で破砕していない使用済イオン交換樹脂ス

生じない。Furthermore, it exhibits approximately the same viscosity as uncrushed used ion exchange resin slurry at high flow rates. FIG. 3 shows this relationship replaced by the relationship between pressure loss and flow velocity. Pressure loss is proportional to the product of the viscosity and the square of the flow rate, so the pressure drop in a slurry of crushed used ion exchange resin, which has high viscosity in the low flow rate area, is the same as that of uncrushed used ion exchange resin. The pressure loss does not exceed the pressure drop in the normal transfer flow rate range used for slurry transfer, and no problem occurs in slurry transfer.

おける擬塑性流体の機能を持たせるのに充分となる。As a means of crushing the used ion exchange resin and turning the used ion exchange resin slurry into a pseudoplastic fluid, the used ion exchange resin slurry is passed through a crusher or through a pump, and the impeller of the pump is used to crush the used ion exchange resin slurry. A method of crushing can be used. FIG. 4 shows the relationship between the viscosity of a slurry of used ion exchange resin in a low flow rate region and the number of times the used ion exchange resin passes through a centrifugal pump. As shown in FIG. 4, when a centrifugal pump is used, the viscosity of the slurry of used ion exchange resin remains approximately constant after passing the used ion exchange resin through the pump approximately 400 times. This is sufficient to provide the function of a plastic fluid.

る。In this embodiment, the used ion exchange resin generated when each ion exchange resin is used is sent to the storage tank 2. The used ion exchange resin sludge IJ- in the storage tank 2 is circulated through the circulation pipe 3 and the circulation bomb f4, and is further ejected into the storage tank 2 by the eductor 5, thereby preventing sedimentation and clogging in the storage tank 2. .

スラリーは移送配管９によシ郡送先１０に移送される。A part of the used ion exchange resin slurry being circulated is extracted through the branch pipe 6, sent to the crusher 7, crushed, and then returned to the storage tank 2. When the predetermined crushing is completed, the three-way valve 8 is turned off, and the crushed used ion exchange resin slurry is transferred to the destination 10 via the transfer pipe 9.

5m square x 4 inertia), the capacity of circulation pump 4 is 10
0 m"/Hr. Of the used ion exchange resin slurry that is circulated, 50 m"/Hr is from the eductor 5.
The remaining 50 m3/hr is returned to the storage tank 2 through the crusher 7. At this time, the flow rate from the eductor 5 is set to be sufficient to prevent uncrushed used ion exchange resin from settling and clogging in the storage facility.
また破砕器７は、遠心ポンプに比べて１０倍以上の破砕
効率が期待できるので、使用済イオン交換樹脂は破砕器
７を４０回以上通過すれば良く、破砕に要する時間は約
８０時間である。Furthermore, since the crusher 7 can be expected to have a crushing efficiency more than 10 times that of a centrifugal pump, the used ion exchange resin only needs to pass through the crusher 7 at least 40 times, and the time required for crushing is approximately 80 hours. .
破砕が完了すると貯槽２内の使用済イオン′９：換樹脂
スラリーは約２時間で移送先１０へ移送される。When the crushing is completed, the spent ion '9:resin slurry in the storage tank 2 is transferred to the destination 10 in about 2 hours.

The supply tank 2 is further circulated by the eductor 15.
This prevents sedimentation and clogging within the supply tank 12.

m" (diameter 2 m x a m height), the capacity of the circulation bong 7'14 is 100 m"/'Hr. If the pump 14 is a centrifugal pump, the used ion exchange resin only needs to be passed through the pump 400 times or more, so the time required for crushing is 40 hours.
