や不燃物（金属類）が混入している。As a volume reduction treatment for combustible miscellaneous solids generated from nuclear power plants, a method for granulating incineration ash generated after incineration of combustible miscellaneous solids is discussed in JP-A-60-69600. However, due to differences in incineration operating conditions such as the incinerator cleaning process and the incineration of replacement parts during periodic inspections, the incinerated ash discharged from the incinerator contains coarse-grained incinerated ash and non-combustible materials (metallic materials). ) are mixed in.
上記従来技術は、焼却炉炉底から排出される焼却灰中に
含まれる下記不燃物の選別処理について配慮されていな

本発明の目的は、粗粒径焼却灰及び不燃物の選別造粒処
理による焼却灰減容処理（中間貯蔵システムに適したペ
レツ１への生成）設備を提供することにある。An object of the present invention is to provide equipment for reducing the volume of incinerated ash (producing pellets 1 suitable for intermediate storage systems) by sorting and granulating coarse-grained incinerated ash and incombustibles.
−１−北口的は、粗粒径焼却灰及び不燃物の選別するこ
とにより達成される。-1-Kitaguchi is achieved by sorting out coarse-grained incineration ash and incombustibles.

より粗粒径焼却灰を選別しドラ１１缶へ充填し、均一粒
径焼却灰だけを処理し、ていては最大減容を達成できな
い為これは採用しがたい。Coarse particle size incineration ash can be sorted using a vibrating sieve or the like. However, if the incinerated ash of coarse particle size is sorted by a sieve or the like and filled into the drum 11 and only the incinerated ash of uniform particle size is processed, the maximum volume reduction cannot be achieved, so this method is difficult to adopt.
従って、焼却灰中に含まれる粗粒径焼却灰を造粒処理条
件（粒径５ｗ１以下）を満足する粒径に処理すべく焼却
灰粉砕機を切替ダンパ下流側へ設置する。Therefore, an incineration ash crusher is installed downstream of the switching damper in order to process the coarse-grained incineration ash contained in the incineration ash into a particle size that satisfies the granulation processing conditions (particle size 5w1 or less).
金属の選別については、フルイを用いた選別が考えられ

の特性を利用する手法の一つである焼却灰と金属の比重
の違いを利用し選別処理を行う。即ち、金属混入焼却灰
に一定流速、流量のエアーを供給し比重の軽い焼却灰だ
けが流動するという事を利用し選別処理を行う。Regarding the sorting of metals, it is possible to sort using a sieve, but since the sieve (metallic mesh) cannot completely separate the metals, this cannot be adopted. Another possibility is electromagnetic iron removal that takes advantage of the properties of metals, but this cannot be used as the metals lose their magnetism during the incineration process. Therefore, sorting is carried out by utilizing the difference in specific gravity between incinerated ash and metal, which is one method that utilizes the characteristics of metals. That is, a sorting process is performed by supplying air at a constant flow rate and flow rate to the metal-containing incineration ash, and taking advantage of the fact that only the incineration ash with a light specific gravity flows.
焼却装置より発生する焼却灰の粒径は、焼却装置の運転
条件によりある程度予測できる。The particle size of the incinerated ash generated from the incinerator can be predicted to some extent depending on the operating conditions of the incinerator.

粒径は、ばば造粒可能な粒径範囲を有しているため切換
ダンパーを用いて焼却灰選別装置へ供給する事により粉
砕機への負荷を低減する。Therefore, since all of the incinerated ash generated during the incinerator cleaning process has a particle size, it is fed to an incinerated ash pulverizer using a switching damper, and the incinerated ash is sized to a particle size range that can be granulated. On the other hand, the particle size of incinerated ash generated during normal operation of the incinerator is within the particle size range that can be granulated, so by supplying it to the incinerated ash sorting device using a switching damper, the load on the pulverizer can be reduced. reduce
焼却灰選別機への焼却灰供給については、ロータリーバ
ルブを採用して定量供給し、流動層での焼却灰の完全流
動化、焼却灰移送配管内での閉塞を防止する。Regarding the supply of incinerated ash to the incinerated ash sorter, a rotary valve is used to supply a fixed amount of incinerated ash to completely fluidize the incinerated ash in the fluidized bed and prevent clogging in the incinerated ash transfer piping.

混入金属類が造粒装置系へ移送される事はない。In order to completely separate the incinerated ash from metals in the fluidized bed, the fluidized bed is made into a vertical cylinder and air is supplied from the bottom, and the suction nozzle is set in two parts. Only the incinerated ash is fluidized, and no mixed metals are transferred to the granulator system.
以上の様に造粒可能焼却灰粒径範囲への整粒及び流動層
を用いた金属の選別により、円滑な焼却灰造粒処理が可
能となる。As described above, smooth granulation of incinerated ash becomes possible by sizing the incinerated ash into a particle size range that can be granulated and by selecting metals using a fluidized bed.
