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 conical drying device, in particular to a conical drying device for waste resin in a nuclear power plant. Background technique [0002] Under the circumstance that the treatment and disposal of radioactive waste is becoming more and more prominent, the traditional waste resin cement solidification process treatment technology has a large capacity increase of the final waste body, which does not meet the principle of minimizing nuclear power waste; the waste resin generated by some operating nuclear power plants in China is still in temporary storage. status; this puts pressure on the temporary storage of the site waste bank 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, which have been applied in some nuclear power plants. my country's new AP1000 third-generation nuclear power plant has introduced new technolog...
