Abstract

The invention discloses a conic nuclear power plant waste resin drying device. The conic nuclear power plant waste resin drying device comprises conic dryer body equipment used for waste resin vacuum drying, a hot oil unit used for heating and cooling a conic dryer, an air exhausting and condensation system used for maintaining the vacuum degree in a dryer body and condensing steam, a nitrogen purging system used for protecting the system and washing a washable filter, a washing and dewatering system used for dewatering waste resin and washing system pipelines, and a resin barreling system used for simulating a nuclear island SRTF station. The provided conic nuclear power plant waste resin drying device is safe, reliable, easy to operate and control, reasonable in structure configuration, high in drying efficiency and large in resin volume reduction ratio.

Description

technical field [0001] The invention relates to a cone-shaped drying device, in particular to a cone-shaped drying device for nuclear power plant waste resin. Background technique [0002] As the treatment and disposal of radioactive waste solids become more and more prominent, the traditional waste resin cement solidification process technology has a large increase in the final waste volume, which does not meet the principle of nuclear power waste minimization; waste resin produced by some domestic nuclear power plants is still in temporary storage status; all of which put pressure on the temporary storage of the site waste repository and the operation of the nuclear power plant. At present, countries such as Germany, France and the United States have developed radioactive waste drying devices, and have been applied in some nuclear power plants. my country's new AP1000 third-generation nuclear power plant has introduced new technologies such as waste resin drying and hot p...
