固化する。In the melting apparatus 1 having the above configuration, melting raw materials such as radioactive waste are melted in the following manner. That is, the bolt 11 is opened and the melted raw material is charged from the charging port 9, and the raw material is charged into the melting space 6 through the charging cylinder 8. The charged molten raw material is irradiated with a plasma arc from a plasma torch 14, 15 to melt it. The molten material produced by the melting process in step 1 is caused to flow out from the outlet 16 and into the flow path 1.
7 into the inside of the granulating device 2 from the outlet 18. In the granulating device 2, the molten material is granulated as follows. That is, cooling water is made to flow through the cylinder 22, the top plate 24, and the diaphragm 27, respectively. Also, the drive device 42
The rotating disk 88 is rotated at a predetermined number of rotations. When the molten material falls from the receiving port 26 onto the concave rotary disk 88 in a solid state, the molten material forms a pool in the recess, and the subsequent molten material falls onto the disc due to this pool. Rather than being directly cooled, it is dispersed in all directions by centrifugal force. In the process of dispersing the molten material like kernels, the molten material becomes granular, and during the flight process, it begins to solidify in a shape close to a sphere, and it becomes a cylinder being cooled! ! It bounces off the inner surface of 2 and falls onto the diaphragm 27. Also, in this process, the granules produced by the above granulation are completely solidified.

前記の範囲内で定めるのが適当である。The granules that have fallen onto the diaphragm 27 in the tilted state are sequentially moved downward in the tilt direction (to the right in the figure) by the vibration of the water-cooled diaphragm 27. During this movement process, the granules are sequentially cooled. The rotational speed of the rotating disk 88 is determined depending on the supply amount, fluidity, degree of mixing of metals and inorganic substances, etc. of the melt dropped onto the rotating disk 88, so that the melt can be appropriately granulated. It is appropriate to set it within the above range so that the

That is, the particulate matter that has moved above the diaphragm 27 to its lowest position enters the packet 64. This packet 54 moves in the direction of the arrow by the movement of the chain 6s and reaches above the hopper 55. Above the hopper 56, the granules in the packet 54 are transferred to the hopper 65.

and packed into an arbitrary container not shown.

なることが防止され、確実に粒状化が行なわれる。When the melt is granulated by the granulating device 2 as described above, the inner diameter of the cylinder 22 is set to 1000 mm or more as described above, and the rotation speed of the rotating disk 88 is set to SOO per minute.
~/300 revolutions, so even if the molten material is a mixture of various metals and inorganic materials, the molten material will surely scatter from the rotating disk in the form of particles as described above. In the process of falling onto the diaphragm, particles are prevented from adhering to the rotating disk or cylinder and becoming stuck, or from being fused together to form a lump, thereby ensuring granulation.

化にも適応できる利点がある。As described above, in the present invention, the concave rotary disk 88 is disposed in the center of the hollow cylinder 22, and the inner diameter of the cylinder 22 is set to 7000 m or more. Since the rotational speed is set at jOO~/300 revolutions per minute, if the melt is to be granulated, if the melt is a melt of a metal with a high melting point, or if it is a melt of an inorganic material, Of course, even in the case of a mixture of solid and molten substances, once they accumulate in the recesses, they are prevented from being cooled by the disk, and can be scattered from the disk as a molten substance at a uniform temperature. They can be granulated and have the versatility to adapt to various raw materials. That is, it has the advantage that it can be applied, for example, to granulating melted radioactive waste containing a mixture of various materials.
