The atmospheric pressure discharging multi-mode conversion apparatus comprises a high-voltage power supply,a resistor, a cavity body, a high-voltage electrode, a ground electrode and a micrometer caliper, wherein one end of the high-voltage electrode is connected with the output end of the high-voltage power supply through the resistor; the ground electrode is placed in the cavity body; the spacing between the high-voltage electrode and the ground electrode can be adjusted through the micrometer caliper; by adjusting the spacing between the high-voltage electrode and the ground electrode, conversion of multiple discharging modes can be realized between the high-voltage electrode and the ground electrode, such as corona discharge, silk-form discharge, similar glow discharge, glow discharge and spark discharge; and by virtue of the apparatus, the problems of instable and discontinuous discharging mode and incapability of realizing or controlling conversion of multiple discharging modes existing in the current atmospheric pressure discharging mode generation apparatus can be solved.

Description

technical field [0001] The invention belongs to the field of gas discharge and discharge plasma, and in particular relates to a device for converting multiple discharge modes under atmospheric pressure. Background technique [0002] Gas discharge is a phenomenon observed when a gas or vapor is electrically conductive. The ionosphere of the atmosphere, lightning in nature, corona discharge on transmission lines, and arc discharge during switch closure are all common gas discharge phenomena. Most of the research on these discharges has been carried out at low pressure, but these discharges often occur at atmospheric pressure. Atmospheric pressure discharge plasmas have potential applications in biomedicine, surface treatment, chemistry, biological decontamination, flow control, and combustion. [0003] Many of these applications require the generation of atmospheric pressure non-equilibrium plasmas (such as corona discharge, glow discharge and spark discharge) to meet the re...
