Abstract

The invention provides a reactor and a supercritical water oxidation treatment system, and relates to the technical field of reaction equipment safety, the reactor comprises a reaction tank and a reactant injection device, and the reactant injection device is installed on the reaction tank; the reactant injection device comprises a reactant inlet pipe which is arranged on the tank wall of the reaction tank in a penetrating manner; a guide mechanism which is mounted at one end, inserted into the reaction tank, of the agent inlet pipe, and is used for controlling the reactant injected into the reaction tank by the agent inlet pipe to rotate around the axis in the height direction in the reaction tank; and a speed regulating device which is connected with the agent inlet pipe and is used for controlling the agent outlet speed of the guide mechanism. According to the invention, the reactant is injected into the reaction tank through the reactant inlet pipe, and the reactant in the reaction tank is controlled to rotate around the vertical axis and form cyclone through the guide mechanism, so that residues and corrosives generated by reaction of the reactant flowing through an area can be quickly discharged downwards, the flowing area of reaction products is controlled, and the tank wall is prevented from being corroded by acidic corrosive substances and the like in reaction products.

Description

technical field [0001] The invention relates to the technical field of reaction equipment safety, in particular to a reactor and a supercritical water oxidation treatment system. Background technique [0002] The critical water oxidation technology (Supercritical Water Oxidation, SCWO) is an advanced oxidation technology that uses the special properties of the oxidant in the supercritical state to make the organic matter and the oxidant react rapidly in supercritical water to completely decompose the organic matter. SCWO is a new waste treatment technology proposed and developed by American scholar Modell in the 1980s. It has the characteristics of energy saving, high efficiency and strong applicability, and has attracted the attention of environmental protection workers at home and abroad. [0003] Supercritical water oxidation technology can treat various toxic organic wastewater, organic waste, sludge and human metabolites. Compared with other traditional methods, it has ...
