A rotating concentric circle dielectric barrier micro-slit discharge pollutant treatment device

Abstract

The invention discloses a rotating concentric circle dielectric barrier micro-gap discharge pollutant treatment device, which is characterized by comprising a water tank, a gas static pressure tank and a rotating tank; the water inlet of the water tank is connected with the water inlet pipe, and the water outlet of the water tank is connected to the water tank. The water outlet pipe is connected; a ground electrode is arranged in the water tank; the gas static pressure box includes a high-voltage wire interface and an air inlet; the high-voltage wire interface is connected to the high-voltage stage of a high-voltage power supply, and the air inlet is connected to an air inlet pipe; the The rotating box includes rigid high-voltage wires, high-voltage electrodes, insulating medium and micro-gap components; the rotating box is connected with the water tank and the gas static pressure box through a bearing; the rotating box is connected with a motor through a belt to realize the rotating function; The rigid high-voltage wire is connected with the high-voltage electrode; the rigid high-voltage wire is connected with the rotating box through a bearing, and the entire high-voltage electrode part is in the rotating box but does not rotate together with the box; the high-voltage electrode is close to the rotating box Insulating medium; the micro-slot component is cylindrical and contains several longitudinally-arranged micro-slot channels. The invention can realize automatic cooling during discharge, uniform water treatment, and high-efficiency degradation of organic pollutants.

Description

technical field [0001] The invention belongs to the technical field of pollutant treatment, in particular to a rotating concentric circle dielectric barrier micro-gap discharge pollutant treatment device. Background technique [0002] Only about 0.007% of the water on earth can be directly used by human beings. my country is one of the thirteen water-poor countries designated by the United Nations, and China's per capita freshwater resources are only one-fifth of Russia's. At the same time of serious shortage of water resources, my country's water pollution is also facing a more severe situation. One of the main sources of water pollution in my country is industrial organic wastewater that is directly discharged without treatment or treated but still does not meet the discharge standard. In recent years, people have paid more and more attention to the impact of organic synthetic dye wastewater in the textile industry on the environment. About 70% of the dyes in the world be...
