The invention provides a supercritical water oxidation system. The system comprises a water supply device, wherein the water supply device is used for providing water and a target solution; an oxidantfeeding device is used for providing an oxidizing agent for the supercritical water oxidation reaction; a solid combustible material chopping and pulping machine is used for grinding the solid combustible materials into slurry; a supercritical water oxidation reactor is used for receiving the slurry, an oxidizing agent, the water and the target solution obtained after grinding the solid combustible material; and a separation equipment is used for separating the effluent of the supercritical water oxidation reactor. The device further provides a method for treating the solid combustible by using the supercritical water oxidation system.
Description
technical field [0001] The present disclosure relates to a supercritical water oxidation system and a method for treating solid combustibles using the supercritical water oxidation system. Background technique [0002] Supercritical water oxidation is a new type of wet oxidation technology. By utilizing the characteristics of organic waste, water, and oxygen being completely miscible in supercritical water systems, organic matter is oxidized and decomposed into gases such as water, carbon dioxide, and nitrogen, and the radionuclides contained in them are converted into inorganic salts, thereby completing the distillation of organic solvents. Liquid handling. Generally, supercritical water refers to water in a special state with a temperature exceeding 374°C and a pressure exceeding 22Mpa. In the state of supercritical water, organic waste and oxygen are completely miscible in the supercritical water system. When the temperature of supercritical water exceeds 550 ° C, the s...
