Wide-interval electronic inducing plasma generator

Abstract

The invention provides a wide-interval electronic inducing plasma generator, which comprises a positive plate and a negative plate. The positive plate is formed by evenly-distributed round spikes in an arraying mode, and point discharge is formed. The negative plate is composed of a planar copper plate, and an electronic inducing discharge generator is arranged between the positive plate and the negative plate. Each inducing wire in the electronic inducing discharge generator is composed of a small round piece, a small ring and a thin wire, wherein each small ring sleeves a small shaft which is mounted on a frame, the position of each thin wire is fixed with a spring, and before the positive plate and the negative plate are electrified, the small round pieces and the thin wires are perpendicularly arranged between the positive plate and the negative plate. The electronic inducing discharge generator shrinks the discharge space distance and can expand discharge space at the same time, and the yield of plasmas is increased. By means of the inducing discharge generator, point discharge of the round spikes and double-dielectric barrier discharge of the positive plate and the negative plate, initial discharge voltage is lowered, the requirements for voltage and frequency of a pulse power supply are lowered, and the wide-interval electronic inducing plasma generator is suitable for industrial large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of plasma generators, in particular to a wide-gap electron-induced plasma generator. Background technique [0002] The electrons in the material atoms are separated from the attraction of the nucleus to form a state where negatively charged free electrons and positively charged ions coexist. At this time, the charges of the electrons and ions are opposite, but the number is equal. This state is called a plasma state. [0003] Plasma as a means of flue gas purification is currently at the forefront of domestic and foreign research technologies, but most of them are in the stage of laboratory exploration and remain in the state of theoretical research. The main difficulty is that the wide-gap discharge requires extremely high voltage (30kv / cm in the air); the laboratory uses organic gases, such as Ar (argon), He (helium), etc., which are almost impossible to promote in engineering applications and are safe.
