Generation of atmospheric pressure diffuse dielectric barrier discharge based on multiple potentials in air
|
摘要
In order to achieve atmospheric pressure diffuse dielectric barrier discharge(DBD) in air, a helical-helical electrode structure with a floating-voltage electrode is proposed in this paper.Results from an electric field distribution simulation indicate that strong electric fields are formed where the helical-contact electrodes' insulating layers are in contact with each other, as well as near the floating-voltage electrode, which contributes to the production of a large number of seed electrons. The electric field within the air gap is weak(<3?×?10~6 V m~(-1)), which inhibits the rapid development of electron avalanches and the formation of filament discharge. The experimental result shows that a 3.0 mm width diffuse DBD is generated in air. Moreover, based on the study of the helical-helical electrode with a floating-voltage electrode, a threedimensional electrode structure is presented, and a three-dimensional diffuse discharge is generated in air by adopting this electrode structure. The plasma studied is stable and demonstrates good diffusion characteristics, and therefore has potential applications in the field of exhaust gas treatment and air purification.
