Title:
SEALED PLASMA MELTING FURNACE FOR TREATING MEDIUM- AND LOW-LEVEL RADIOACTIVE WASTE
Document Type and Number:
WIPO Patent Application WO/2018/021682
Kind Code:
A1
Abstract:
The present invention relates to a sealed plasma melting furnace (10) for treating medium- and low-level radioactive wastes, which is capable of batch-processing the medium- and low-level radioactive wastes regardless of the types thereof according to the characteristics of each waste in a sealed state to thus minimize secondary pollutants. The sealed plasma melting furnace comprises: a waste supply chamber (100), provided with a hopper (110) on one side thereof in communication therewith, in which waste introduced from the hopper (110) is stacked in a vertical direction; a pyrolysis chamber channel (210) provided on one side of the waste supply chamber (100) and communicated with the waste supply chamber (100); a pyrolysis chamber (200) provided on one side of the pyrolysis chamber channel (210) and having a burner mounted thereon; a melting chamber channel (310), provided on one side of the pyrolysis chamber (200), which guides the waste conveyed from the pyrolysis chamber (200) communicating therewith and has a nozzle (311) for injecting liquid waste on one side thereof; a melting chamber (300), provided on one side of the melting chamber channel (310), which has a plasma torch (320) mounted on one side thereof and has a furnace inside for accommodating a molten material formed at a bottom surface thereof; a molten processed product discharging channel (350), provided at a lower portion of the melting chamber (300), for discharging the molten processed product generated in the melting chamber; a secondary combustion chamber channel (410), provided on one side of the pyrolysis chamber (200), for inducing and exhausting a flow of an exhaust gas generated in the melting chamber (300); and a secondary combustion chamber (400), provided on one side of the secondary combustion chamber channel (410), for inducing a complete combustion of the exhaust gas introduced from the secondary combustion chamber channel (410) communicating therewith.
