Supercritical water oxidation treatment system and regulation and control method thereof

Abstract

The invention discloses a supercritical water oxidation treatment system and a regulation and control method thereof, an integrated reactor is internally provided with a heating device, an emergency heat collector, a mixing water preheater, a material preheater and a wall surface cooler in an integrated manner, so that multi-path and gradient comprehensive utilization of supercritical water oxidation reaction heat release and overtemperature prevention guarantee of the wall surface of the reactor are realized; the organic waste is directly mixed and heated, the material adaptability is high, and an online continuous or timed intermittent diverse salt removal and discharge mode can be adopted; multi-stage automatic regulation and control measures are set according to key system parameters such as flow, temperature and pressure, and the method can be widely applied to high-safety and efficient innocent treatment of various organic wastes.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment, and in particular relates to a supercritical water oxidation treatment system and a control method thereof. Background technique [0002] At present, various fields of industrial production will generate a large amount of organic waste, such as printing and dyeing wastewater, medical waste, chemical wastewater, etc., the content of organic pollutants is different, the salt content is very different, and it is usually difficult to biochemically degrade, which greatly increases the difficulty of treatment. Traditional treatment methods not only fail to effectively reduce and detoxify organic wastes, but also produce leachate to pollute groundwater, produce dioxins and SO2 2 and other harmful gases, further deteriorating the living environment of human beings. In addition, most of the current conventional treatment methods can only deal with specific organic wastes, and the scope of...

AI Technical Summary

Problems solved by technology

However, the problem of corrosion failure caused by inorganic salt in the organic waste to be treated and the problem of equipment blockage caused by salt crystallization have seriously affected the safety of the device operation; in addition, the fluctuation of flow, pressure and temperature during the operation of the system will also affect The system is running normally
