Description
【発明の詳細な説明】 〔産業上の利用分野〕 棄物固化処理方法およびそのための装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a waste solidification treatment method and an apparatus therefor.
従来、放射性廃棄物の固化処理方法としては、下記の様
な方法が提案されている。Conventionally, the following methods have been proposed as methods for solidifying radioactive waste.
(1)液状の廃棄物の固化方法としては、固化材として
セメントを用いる方法がある。これは、固化容器内に、
所定量の放射性廃棄液を充填し、その後、所定量のセメ
ントを投入しながら同化容器内で攪拌羽根により攪拌し
てセメントペーストとし、固化容器内に固化する方法で
ある。(1) As a method for solidifying liquid waste, there is a method using cement as a solidifying material. This is in a solidification container.
This is a method in which a predetermined amount of radioactive waste liquid is filled, and then a predetermined amount of cement is poured into the assimilation container while being stirred with a stirring blade to form a cement paste, which is then solidified in a solidification container.
この様に、固化容器内で混練して固化する方法をインド
ラム固化法という。一方、放射性廃液とセメントの混線
操作を混練槽にて行ない、この混練されたペーストを固
化容器内へ充填する方法もあシ、これをアラトド2ム固
化法という。This method of kneading and solidifying in a solidification container is called the in-drum solidification method. On the other hand, there is also a method in which radioactive waste liquid and cement are mixed in a kneading tank and the kneaded paste is filled into a solidification container, which is called the Aratodo 2m solidification method.
(2) 放射性廃棄物を粉体化した後に固化処理する
方法としては、グラスチック固化法、があ、る(特開昭

射性廃棄物を乾燥粉体化した後、廃棄物粉体と固化材で
あるグラスチックとを混練槽にて混練して、固化容器内
に混練する方法である。(2) As a method for solidifying radioactive waste after pulverizing it, there is a glass solidification method (Japanese Unexamined Patent Publication No. 53-40199). This method uses a dryer to solidify liquid radioactive waste. This is a method in which the waste powder is dried and powdered, and then the waste powder and a solidifying material, ie, glasstic, are kneaded in a kneading tank and then kneaded in a solidifying container.
(3)廃棄物を乾燥粉体化した後、ペレットに成形し、
この被レットを同化処理する方法が、あ4る(特開昭5
2−85699号)。この方法では、ペレットを固化容
器に充填した後に、上部よシ固化材を注入してペレット
の間げきを充填しペレットを固化容器内に固定化する。(3) After drying and powdering the waste, mold it into pellets,
There are four ways to assimilate this target (Japanese Patent Laid-Open No. 1983-1933).
No. 2-85699). In this method, after filling a solidification container with pellets, a solidification material is injected into the upper part to fill the gaps between the pellets and fix the pellets in the solidification container.
前述のような、混練槽内で廃棄物と同化材とを混線する
固化処理方法では、混練槽が廃棄物で汚染されるので定

浄設備や2次廃棄物の処理設備が必要となり、処理設備
が大規模となる。In the above-mentioned solidification treatment method in which waste and assimilated materials are mixed in the kneading tank, the kneading tank becomes contaminated with waste and requires periodic decontamination or cleaning. Even in the method of kneading with stirring blades, periodic decontamination or cleaning of the stirring blades is required. In these cases, decontamination φ
Secondary waste is generated due to cleaning, and decontamination/cleaning equipment and secondary waste processing equipment are required, making the processing equipment large-scale.

の充填された固化容器上部よシ固化材を注入しただけで
は、固化容器下部まで固化材が流下せず、固化容器内の
廃棄物を一体化することが難しい。In addition, in the solidification method of pellet-shaped waste as described above, a kneading tank for the solidification material is still required, and if some particles such as paris or powder are mixed in, the pellet If the solidifying material is simply injected from the top of the solidifying container filled with solidification material, the solidifying material will not flow down to the bottom of the solidifying container, making it difficult to integrate the waste in the solidifying container.
また、粘性の低い固化材を選定・開発する必要がある。Additionally, it is necessary to select and develop a solidifying material with low viscosity.

はそのまま固化容器内で固化される。The waste and solidification material filled in the solidification container are uniformly kneaded by rolling the entire solidification container so that the solidification container acts as one kneading tank. It is preferable to rotate the axis thoroughly in the up-down and left-right directions. After kneading by rolling the solidification container, the mixture of radioactive waste and solidification material in the solidification container is solidified as it is in the solidification container.
