Abstract
The invention discloses a device for generating oxygen active substances by mesh-shaped creeping surface discharge plasma, which comprises a mesh-shaped creeping surface discharge plasma reactor, an oxygen-containing gas generator and a power supply, and the reactor includes at least one mesh-shaped creeping surface A discharge plasma module, the module includes an array discharge electrode system or a tubular discharge electrode system with high-voltage wiring electrodes and low-voltage wiring electrodes; the array discharge electrode system is composed of several groups of discharge plates, and each group of discharge plates is It consists of the first metal plate as the high-voltage wiring electrode and the second metal plate as the low-voltage wiring electrode; the tubular discharge electrode system is composed of several sets of electrode tubes, each set of electrode tubes is made of the second metal tube as the high-voltage wiring electrode, The first metal tube is used as a low-voltage wiring electrode. The invention can effectively solve the technical problem of large gas resistance of dielectric barrier discharge in two forms of bulk discharge and packed bed.
Description
technical field [0001] The invention belongs to the technical field of plasma application, and in particular relates to a device for generating oxygen active substances by mesh-shaped creeping discharge plasma. Background technique [0002] Plasma is a type of conductive fluid composed of electrons, ions, free radicals and neutral substances. Oxygen reactive species (O 3 , ·OH, ·O, H 2 O 2 etc.) have strong oxidizing properties, and can directly or indirectly undergo rapid and efficient oxidation reactions with compounds in the gas phase or liquid phase, and realize the reaction process that is difficult to achieve by conventional methods. good application prospects. [0003] Dielectric barrier discharge is one of the effective methods to generate low-temperature plasma under atmospheric pressure. It has the advantages of high electron energy, high electron density, and high application effect, and is widely favored by plasma technology users. Dielectric barrier dischar...
