1. A reactor based on supercritical water oxidation, comprising an inner shell and an outer shell, wherein the inner shell is coaxially disposed in the outer shell;

  • the inner shell is divided into two portions, namely an upper cylinder and a lower cone;

    the cylinder comprises an upper segment of imporous pipe (1411) and a lower segment of straight porous pipe (1404); and

    the cone is a conical porous wall (1407);

    the outer shell comprises an upper connection flange, a middle straight pressure-bearing wall (1403) and a lower conical pressure-bearing wall (1409);

    a first annular space is formed between the cylindrical portion of the inner shell and the straight pressure-bearing wall (1403) and the connection flange;

    a second annular space is formed between the conical porous wall (1407) and the conical pressure-bearing wall (1409);

    a separation ring (1405) is disposed between the first annular space and the second annular space;

    high-temperature evaporated water injection pipes (1402) are disposed on an upper portion of the straight pressure-bearing wall;

    low-temperature evaporated water injection pipes (1406) are disposed on an upper portion of the conical pressure-bearing wall (1409); and

    an outlet pipe (1408) is disposed at a bottom of the conical pressure-bearing wall (1409);

    a nozzle pipe (1401) is coaxially disposed on the connection flange, and the nozzle pipe (1401) passes through a top center of the inner shell.
