Anti-blockage supercritical water oxidation reactor as well as anti-blocking device thereof and application

Abstract

The invention relates to the field of environmental friendliness and chemical industry, in particular to an anti-blockage supercritical water oxidation reactor as well as an anti-blocking device thereof and application. The supercritical water oxidation reactor comprises a reactor cavity, a gas-liquid-phase pipeline which is connected to the lower part of the reactor cavity, a flushing pipeline and a slag discharge pipeline, wherein one end of the gas-liquid-phase pipeline extends into the reactor cavity through the side wall of the reactor cavity, and is provided with a downward opening; theother end of the gas-liquid-phase pipeline separately is communicated with a next process unit, the flushing pipeline and the slag discharge pipeline through pipelines; one end of the slag discharge pipeline is connected with the bottom of the reactor cavity, and the other end of the slag discharge pipeline is used for discharging slag; one end of the flushing pipeline is communicated with the reactor cavity through the side wall of the reactor cavity; and the other end of the flushing pipeline is communicated with the gas-liquid-phase pipeline. The anti-blockage supercritical water oxidationreactor completely solves the problem that the outlet of the supercritical water oxidation reactor is blocked.

Description

technical field [0001] The invention relates to the fields of environmental protection and chemical industry, in particular to an anti-clogging supercritical water oxidation reactor and its anti-clogging device and application. Background technique [0002] Supercritical Water (SCW for short) refers to water in a special state whose temperature and pressure are both higher than its critical point (T=374.15°C, P=22.12MPa). Supercritical Water Oxidation (SCWO) technology is a technology that can realize deep oxidation treatment of various organic wastes. It uses the unique physical and chemical properties of supercritical water to completely dissolve oxidants and organic substances in supercritical water. With supercritical water as the reaction medium, through a homogeneous oxidation reaction, the organic matter is quickly and thoroughly converted into clean CO 2 、H 2 O, N 2 And other harmless small molecules, so that S, P, etc. are converted into the highest valence salts...
