Embodiment Construction

[0020] see figure 1 , is a supercritical water treatment reactor with a porous evaporation wall and a pressure balance device installed. The supercritical water treatment reactor mainly includes: a pressure-bearing wall 1, a porous evaporation wall 2 similar in shape is arranged inside the pressure-bearing wall 1, the inside of the porous evaporation wall 2 is a reaction area, and the pressure-bearing wall 1 and the porous evaporation wall 2 The cavity between them is filled with evaporated wall water. The bottom of the porous evaporation wall 2 is the outlet of the salt-containing fluid, and the top is the outlet of the reaction fluid. The material and oxidant are supplied through the conduit 8 extending into the middle and lower part of the porous evaporation wall 2 . The evaporating wall water main pipe 3 is connected with a header 7, and the header 7 branches out into multiple evaporating wall water branch pipes 8, which respectively communicate with the cavity between th...

Abstract

The invention belongs to the treatment field of waste organics, relates to a reactor utilizing super-critical water treatment technology to realize harmless treatment of waste organic and resource recycling and discloses a pressure balancing device for super-critical water treatment reactor with porous evaporator wall. The pressure balancing device comprises an evaporator wall water header and a balancing pipe whose one end extends into the inner side of the evaporator wall; the other end of the balancing pipe is divided into two paths, wherein, one path is communicated with the evaporator wall water header by a positive conducting pressure drop balancing valve, and the other path is communicated with the evaporator wall water header by a reverse conducting pressure drop balancing valve.

Description

technical field [0001] The invention belongs to the field of waste organic matter treatment, and relates to a reactor for harmless treatment and resource utilization of waste organic matter by using supercritical water treatment technology, in particular to a pressure balance device for a supercritical water treatment reactor with a porous evaporation wall . Background technique [0002] Supercritical water refers to water in a special state whose temperature and pressure are higher than its critical point (T=374.15°C, P=22.12MPa). Supercritical water has the properties of both liquid and gaseous water. In this state, only a small amount of hydrogen bonds exist. The dielectric constant is similar to that of organic solvents. It has a high diffusion coefficient and low viscosity. Under a sufficiently high pressure, organic matter and oxygen can be miscible with supercritical water in any proportion, so that the heterogeneous reaction becomes a homogeneous reaction, which gre...
