Device for producing large-area surface discharge by utilizing water electrodes

Abstract

The invention discloses a device for producing large-area surface discharge by utilizing water electrodes. The device structurally comprises a sealing tank and a discharge device installed in the sealing tank, wherein the discharge device comprises a plurality of sequentially arranged U-shaped tubes. Vertical tubes on each side of the U-shaped tubes are aligned at intervals, adjacent vertical tubes are staggered and arranged in two rows, and an insulating dielectric plate is placed between two rows of adjacent vertical tubes on each side. Horizontal base tubes of the U-shaped tubes are embedded into an insulating rubber layer side by side. The water electrode is placed into one vertical tube of the U-shaped tubes, water electrodes placed in the aligned vertical tubes are jointly connected to one output end of a high-voltage alternating current power supply, and the water electrodes placed in other row of aligned vertical tubes are jointly connected to the other output end of the high-voltage alternating current power supply. Compared with a solid electrode dielectric barrier surface discharge device embedded in an insulating dielectric through metal strips, the heat dissipation problem of a discharge electrode is solved fundamentally, the discharge duration and the service life are prolonged, the discharge efficiency is improved, the manufacture process technological requirement is reduced, and the discharge device manufacture cost is reduced. The device for producing the large-area surface discharge by utilizing the water electrodes has wide application prospect in the fields of ozone synthesis, sterilization and disinfection, material processing, aircraft cloaking and the like.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a device for generating large-area creeping discharge using a water electrode. Background technique [0002] Dielectric barrier creeping discharge is to embed two kinds of linear or comb-shaped electrodes with different polarities in the insulating medium to generate AC gas discharge on the surface of the medium. The discharge area along the surface has the characteristics of concentrated energy, high power density, good surface, and easy to generate large area. In recent years, surface discharge has broad application prospects in many fields such as ozone synthesis, sterilization and disinfection, sewage treatment, material growth, surface modification, plasma display, and plasma stealth of spacecraft. [0003] The previous creeping discharge device used metal strips embedded in the insulating medium to make electrodes to realize discharge. Such a discharge device not only has...
