Abstract

The invention provides a device and a method for generating a flaky plasma plume. The device comprises a rectangular medium gas channel and a pin electrode; one end of the rectangular medium gas channel is open, the other end of the rectangular medium gas channel is provided with a gas inlet, a gas supply pipeline is connected between a gas source and the gas inlet of the rectangular medium gas channel, and a gas pressure meter and a flow meter are connected to the gas supply pipeline; and the pin electrode is arranged at the inclined lower part of the open end of the rectangular medium gas channel and is electrically connected with a high-voltage alternating-current power supply. A high-voltage alternating-current voltage is applied to the pin electrode, an air plasma jet is generated, the rectangular medium gas channel is arranged perpendicular to the air plasma jet, sheet-shaped plasma plumes are generated in the open environment of the downstream of the gas channel, and the cross sectional area of the air plasma jet is expanded. The device is suitable for the fields of surface treatment, wastewater purification, sterilization and disinfection, element detection, aircraft drag reduction, aircraft stealth and the like.

Description

technical field [0001] The invention relates to a low-temperature plasma technology, in particular to a device and a method for generating sheet-like plasma plumes by expanding the cross-sectional area of ​​a jet flow with a transverse air flow. Background technique [0002] The plasma jet uses the action of air flow and electric field to make the plasma generated in the discharge area eject from the nozzle or nozzle, and realize the separation of the discharge area and the working area. The plasma plume produced by the atmospheric pressure plasma jet is rich in a variety of active particles, such as OH radicals, O 3 , N in the excited state 2 etc.; there are also a large number of high-energy particles (such as electrons) and ultraviolet rays. These active particles, high-energy particles and ultraviolet rays play a very important role in many fields, such as material processing, element detection, wastewater purification, cancer treatment and tooth whitening.
