SUPERCRITICAL MULTI-ELEMENT HOT FLUID GENERATION SYSTEM AND METHOD WITH SEGMENTED AIR SUPPLY

A supercritical multi-element hot fluid generation system with segmented air supply. An outlet of a water tank (12) of the system is in communication with a preheated water inlet of a multi-element hot fluid generator body (22), a preheated water outlet of the multi-element hot fluid generator body is in communication with a cold fluid inlet of a heat exchanger (6), a product outlet on an upper portion of the multi-element hot fluid generator body is in communication with an inlet for a heat exchanger hot fluid, and a residue outlet on a lower portion of the multi-element hot fluid generator body is in communication with an inlet of a residue discharge lock hopper (14). By means of the rational coupling design of a supercritical water gasification heat absorption area and a hydrogen oxygen heat release area in a multi-element hot fluid generator, the system is self-heated, and high apparatus investment and operation costs caused by an electric heating apparatus are reduced; and a rational desalination solutio
