Corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system

A corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system, comprising:

• a reactor (9), configured to perform supercritical hydrothermal combustion treatment on organic waste;
• an organic waste tank (5), configured to supply the organic waste to the reactor (9), wherein the organic waste tank (5) and the reactor (9) are connected via a first pipeline (18), and the first pipeline (18) is sequentially provided with a first-stage preheater (6), a second-stage preheater (7), and an ejector (8);
• a material outlet end of the reactor (9) is further connected to the ejector (8) via a second pipeline (19), and the ejector (8) is configured to inject supercritical thermal fluid from the material outlet end of the reactor (9);
• an oxidant supply unit, configured to provide oxygen for the supercritical hydrothermal combustion treatment, wherein the oxidant supply unit is further configured to introduce the oxygen into the first pipeline (18) between the first-stage preheater (6) and the second-stage preheater (7) during supplying the oxygen to the reactor (9);
• a hydrogen supply unit, connected to the material outlet end of the reactor (9);
• and
• a membrane separator (12), configured to recover hydrogen from the corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system, wherein the membrane separator (12) is disposed on a third pipeline (20), and two ends of the third pipeline (20) are connected the material outlet end of the reactor (9) and the hydrogen supply unit, respectively;
• a product separator (11) is further provided on the third pipeline (20) between the reactor (9) and the membrane separator (12);
• and
• wherein the third pipeline (20) is connected to a fourth pipeline (21), and an outer pipeline of each of the first-stage preheater (6) and the second-stage preheater (7) is installed on the third pipeline (20);
• the hydrogen supply unit is configured to provide the hydrogen to reduce an oxidation-reduction potential in a subcritical zone cooling section of the corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system, and the outer pipeline of each of the first-stage preheater (6) and the second-stage preheater (7) is the subcritical zone cooling section.
