Wet oxidation enhanced micro-interface system

Abstract

The invention provides a wet oxidation enhanced micro-interface system. The system comprises a wastewater heat exchanger, a wastewater heater and an oxidation reactor; the wastewater heat exchanger isprovided with a material inlet, a material outlet, a heat source inlet and a heat source outlet; oxidized water from the oxidation reactor enters the wastewater heat exchanger from the heat source inlet, and the material outlet is connected with the wastewater heater; liquid outlets are formed in flat parts on two sides of a convex plane on the bottom surface of the oxidation reactor; a liquid inlet and a wastewater inlet are formed in the side wall of the oxidation reactor; liquid ejectors are arranged in the oxidation reactor, the tops of the liquid ejectors are semi-circular arc surfaces,a plurality of ejection holes are sequentially distributed in the semi-circular arc surfaces, the liquid inlet is connected with the bottom of the liquid ejector positioned at the upper part through apipeline, and the wastewater inlet is connected with the bottom of the liquid ejector positioned on the side wall through a pipeline. According to the wet oxidation enhanced micro-interface system, the cost of cleaning and field operation is saved.

Description

technical field [0001] The invention relates to the field of wet oxidation, in particular to a wet oxidation strengthening micro-interface system. Background technique [0002] At present, wet oxidation technology generally operates at relatively high temperature and relatively high pressure, which not only requires relatively high equipment, high energy consumption, and high cost, but also reduces operational safety. The equipment is prone to aging and damage, and oxygen will The residence time in the reactor is short, and most of the oxygen will float out of the reactor without sufficient reaction, which reduces the reaction efficiency and increases the processing cost. [0003] Moreover, the maintenance and cleaning process of the existing wet oxidation reactor requires a lot of manpower, including access to the inside of the oxidation reactor through manholes for cleaning and on-site operation of various pipeline valves. This not only increases the labor cost, but also ...
