INTEGRATED FACILITY FOR TREATMENT OF RADIOACTIVE WASTE USING PLASMA

摘要

The present invention relates to an integrated plasma treatment apparatus for the treatment of medium-level and low-level radioactive waste materials, including a pyrolysis chamber (11) where the pre-heating of the waste materials is performed and a melting chamber (12) where a first plasma torch (13) is provided so that the melting treatment of the waste materials, which are supplied along the pyrolysis chamber (11), is performed. The present invention further includes a vertical reactor (10) where the pyrolysis chamber (11) is provided in a vertical upper portion of the melting chamber (12); a supply device (20) that has a supply unit (21) where a dual gate is provided to be openable and closable so that the supply of a waste material drum (1) into the pyrolysis chamber (11) is performed, a pusher (22) which can move forward and backward so that the waste material drum (1) supplied through the supply unit (21) is pushed into the pyrolysis chamber (11), and a second plasma torch (23) that cuts and breaks the waste material drum (1) supplied to the pyrolysis chamber (11) through the supply unit (21); a melt discharge unit (30) that is provided in a lower portion of the melting chamber to discharge melting slag; circulation piping (40) that connects the melt discharge unit (30) to the pyrolysis chamber (11) to guide the circulation flow of exhaust gas; and an exhaust gas treatment device (50) that is connected to the pyrolysis chamber (11) so that the exhaust gas is secondarily combusted and a dust collection treatment is performed.
