Abstract

The invention belongs to the technical field of environmental protection and chemical engineering, and provides a three-section type supercritical water oxidation device which comprises a reaction kettle device, the reaction kettle device comprises a reaction kettle A, a reaction kettle B and a reaction kettle C which are sequentially and vertically connected from top to bottom, and a settling kettle vertically connected with the reaction kettle C is arranged at the end, away from the reaction kettle B, of the reaction kettle C; and a pollutant inlet is formed in the reaction kettle B, oxidant inlets are formed in the reaction kettle A, the reaction kettle B and the reaction kettle C, and a reactor outlet is formed in the reaction kettle A. The three-section type supercritical water oxidation device can solve the problems of insufficient retention time of solid-liquid mixture reaction materials and difficulty in continuous reaction in the existing supercritical water oxidation technology.

Description

technical field [0001] The invention belongs to the field of environmental protection and chemical technology, and in particular relates to a three-stage supercritical water oxidation device, which is suitable for treating organic waste water and powdery hazardous waste with supercritical water oxidation technology. Background technique [0002] With the rapid economic development and the acceleration of industrialization, environmental issues have become a major global issue facing society today. Supercritical water oxidation technology, proposed in the early 1980s, is one of the most promising pollutant treatment technologies, especially suitable for treating high-concentration organic wastewater, including printing and dyeing wastewater, oily wastewater and landfill leachate. Compared with the traditional treatment process, supercritical water oxidation technology has the characteristics of thorough treatment, short reaction time, no secondary pollution and high controlla...
