加温。Radioactive waste such as radioactive liquid waste or slurry generated at a nuclear power plant or the like is supplied at a predetermined supply capacity from a liquid supply pump 10 to a drying device 14 via a liquid supply valve 3 () and a conduit W50. Here, radioactive waste is a waste! The drying bag f is formed by the centrifugal force of the rotary blade 13 driven and rotated by the device 12.
It is spread into a thin film on the inner wall surface of i14, and is evaporated and dried by the heating of the heating medium flowing through the pipe 52. Evaporated matter passes through conduit 6e to condenser 2
2I is supplied here, is supplied from between the conduits, and is condensed with the cooling water discharged from the conduit 59, and the R agent liquid 1 or 1 is
17t, and is sent to another water treatment device (not shown) through a conduit 57 via a chemical solution outlet valve 35. Further, the non-condensable gas in the evaporated matter is sucked by the suction device n via the vent outlet valve 36, and is sent to another vent treatment device i (not shown) via the vent outlet valve 37 through the conduit 60. On the other hand, the dried material is supplied to one end of the feeder 8 via the dried material outlet pipe 53 and the dried material valve 31, and is transferred to the other end of the feeder 8 by the screw 17 driven by the screw drive device 16. The dried material transferred to the other end of the feeder 8 is fed through the feeder outlet valve 33 and the conduit 55 to the solidification treatment equipment, where it is mixed with a solidified layer of asphalt or plastic, etc., and then passed through the solidified material gate valve. It is supplied and filled into an assimilation drum 70 through a conduit 56 through an aperture. In addition, the drain accumulated at one end of the feeder 8 is extracted and stored in the drain tank 19 via the drain valve 32 and the conduit. In order to perform this series of processing smoothly, it is necessary to keep the radioactive waste processing equipment in good health. must be maintained. In other words, since radioactive waste is usually dried by evaporation to a residual moisture content of several percent by weight or less, the distribution path of the dried material from the drying device 14 to the solidification processing device 21 (hereinafter abbreviated as the distribution path of the dried material) If the machine is not completely dry before operation, dry matter will adhere to areas where moisture remains, and
This leads to the growth of solids and impedes smooth operation. Also,
If the distribution path of the dried material is lower than the temperature of the dried material, that is, close to room temperature, a small amount of residual moisture in the dried material or evaporated matter discharged together with the dried material may enter the distribution path of the dried material. It condenses and adheres, which leads to the adhesion and growth of solids and impedes smooth operation. Therefore, in order to solve these problems and operate the radioactive waste processing equipment smoothly, the radioactive waste processing equipment has conventionally been heated using the following method.
乾燥されている。It has been dried.

通させることでなされている。First, to heat the radioactive waste processing equipment before processing radioactive waste, an electric heater or heating jacket is installed in each passage of the dried material, and the electric heater or heating jacket is used to adjust the passage of the dried material to the temperature of the dried material. For example, drying of the radioactive waste treatment equipment after cleaning is done by heating it to a higher temperature than the dehumidifier RY12!5.
The dehumidified dry air is supplied to the solidification processing device 21 through the conduit 62 between the valves, and the dried material is circulated in the opposite direction through the distribution path.
