Title:
TREATMENT OF RADIOACTIVE ORGANIC SOLID WASTE BY SUPERCRITICAL WATER OXIDATION
Document Type and Number:
WIPO Patent Application WO/2020/156336
Kind Code:
A1
Abstract:
A supercritical water oxidation reactor (100), comprising a housing (101) having a chamber formed therein for providing a reaction zone, the housing (101) being provided with at least a slurry inlet (1011), an oxidant inlet (1012), and a discharge port (1013); a heating apparatus (102) for raising the temperature of the chamber; and a spiral circulating pipe (103) provided in the chamber, one end of the spiral circulating pipe (103) being communicated with the slurry inlet (1011), wherein slurry is introduced into the spiral circulating pipe (103) from the slurry inlet (1011), then flows along the pipeline of the spiral circulating pipe (103), and flows out from the other end of the spiral circulating pipe (103); after flowing out from the other end of the spiral circulating pipe (103), the slurry mixes with an oxidant flowing into the chamber from the oxidant inlet (1012) for oxidation reaction. Further provided are a method for treating a radioactive organic waste using the supercritical water oxidation reactor, a protective apparatus and a reaction system for a reaction device, and a supercritical water oxidation system and a method for treating a solid combustible using the supercritical water oxidation system.
