Abstract

The invention discloses a supercritical water oxidation evaporation wall reactor, which relates to the field of supercritical water oxidation reactors. The evaporating wall reactor includes a cylinder and a cylinder cover. The cylinder cover is provided with a material inlet, an oxidant inlet and a reaction chamber. The reaction chamber is located below the material inlet and the oxidant inlet. The cylinder is equipped with a porous evaporation wall. The water inlet of the upper evaporating wall, the water inlet of the middle evaporating wall, the water inlet of the lower evaporating wall, the upper choke ring, the middle choke ring, The lower throttling ring, the upper throttling ring, the middle throttling ring and the lower throttling ring are located in the annular gap formed by the inner wall of the cylinder and the porous evaporation wall. The evaporating wall reactor of the present application can improve the processing capacity of organic matter, better exert the functions of the evaporating wall reactor in anti-corrosion and salt deposition, and has guiding significance for promoting the structural development and process optimization of the evaporating wall reactor.

Description

technical field [0001] The invention relates to the field of supercritical water oxidation reactors, in particular to a supercritical water oxidation evaporation wall reactor. Background technique [0002] Supercritical water oxidation technology is an efficient method for treating pollutants and refractory organic compounds, which can realize complete oxidation of organic matter without secondary pollution. However, due to the extremely low solubility of inorganic salts in supercritical water, the inorganic salts are easily precipitated, aggregated, and deposited in large quantities, causing adverse effects. The precipitated inorganic salts are easily adsorbed on the heating surface and the inner wall of the reactor to form a salt layer, which leads to the deterioration of heat transfer. Secondly, a corrosion microenvironment "dead zone" will be formed between the salt layer and the heating wall surface. Salt deposition has a synergistic effect on corrosion, and the precipi...
