REACTOR AND REACTION SYSTEM BASED ON SUPERCRITCAL WATER OXIDATION, AND PHENOLIC WASTEWATER TREATMENT METHOD
First Claim
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.

Abstract
The present invention relates to the technical field of wastewater treatment. In the present invention, the reactor is provided with a double-shell reactor, a coaxial nozzle, an inner shell structure, evaporated water injection pipes and the like, so it is assured that the wastewater is inject into the reactor at a room temperature and is degraded thoroughly; moreover, with the evaporated water, the corrosion, salt deposition and local overheating in the reactor are prevented, so that the reaction process is guaranteed to be stable and reliable. and through a fuel system, a hydrothermal flame is formed in the reactor, so that the concentrated waste liquid injected into the reactor at the room temperature can be preheated to a supercritical reaction temperature, and the waste liquid is prevented from coking, scaling and the like in a preheating stage.
