Dielectric barrier discharge-type electrode structure for generating plasma having conductive body protrusion on electrodes

Abstract

Provided is a dielectric barrier discharge-type electrode structure for generating plasma. The electrode structure, according to the present invention, comprises: an upper conductive body electrode and a lower conductive body electrode; at least one conductive body electrode protrusion portion, which is formed on at least one surface of the upper conductive body electrode and / or the lower conductive body electrode; a dielectric layer which is formed on at least one of the inner surfaces of the upper conductive body electrode and the lower conductive body electrode that face each other, so as to have a substantially uniform thickness; and a specific gap (d) which is formed between the upper and lower conductive body electrodes and the dielectric layer, or between dielectric layers, due to the protruding effect of the conductive body electrode protrusion portion when the upper conductive body electrode and the lower conductive body electrodes come into close contact, wherein the plasma is generated by applying a pulse power or an alternating power to the upper conductive body electrode and the lower conductive body electrode.

Description

technical field [0001] The present invention relates to the plasma electrode structure that is applied to air purification system etc. and similar system, relates to the dielectric barrier discharge (DBD, Dielectric Barrier Discharge) type plasma generation electrode structure in more detail, and described electrode knot is stored in gaseous fluid such as air Plasma is generated, and the electrons, ions, and ultraviolet rays generated at this time react with bacteria and odor molecules to decompose harmful gases and sterilize them, thereby purifying the air inside air conditioners, refrigerators, washing machines, and vehicles. Background technique [0002] As indoor air purification becomes increasingly important, various methods for simultaneously removing particles and gaseous substances present in the room have been developed. These air purification technologies include filtration, electrostatic precipitator, plasma, UV / photocatalyst, and hybrid methods. [0003] Among ...

Problems solved by technology

However, according to these methods, a loss of pressure occurs due to the dielectric filled in the reactor, and the reactor is easily clogged when particulate matter is present in the exhaust gas.

Moreover, in order to treat a large amount of exhaust gas, it is necessary to bundle a plurality of tubular reactors into a bundle or a pile, so the size of the treatment system will be greatly enlarged.
