A waste activated carbon treatment device using reduced-pressure heating system

摘要

The present invention relates to an apparatus for treating waste activated carbon using a reduced pressure heating method, and more particularly, to directly process waste activated carbon so that a compact and safe design of a treatment process is achieved, and separation of radioactive material from waste activated carbon through reduced pressure heating The present invention relates to a waste activated carbon treatment apparatus using a reduced pressure heating method. To this end, a storage container for receiving waste activated carbon generated from a nuclear power plant; a heating chamber for heating the waste activated carbon; heating means for directly heating and treating the waste activated carbon in the heating chamber; decompressing the inside of the heating chamber And a decompression means for collecting and treating the radioactive carbon generated during the heat treatment of the waste activated carbon; installed between the storage vessel and the heating chamber, and transferring means for transferring the waste activated carbon from the storage vessel to the heating chamber using differential pressure; A steam generator for injecting steam toward the waste activated carbon of the heating chamber to increase the surface partial combustion efficiency of the waste activated carbon; Inert gas injection device for injecting an inert gas into the heating chamber to purge the heating chamber; The upper and lower portions of the heating chamber have a double structure, and coolant is supplied to the upper and lower portions of the heating chamber. It provides a waste activated carbon treatment apparatus using a reduced pressure heating method characterized in that a cooling water supply device for circulating, to suppress overheating of the heating chamber is provided.
