Abstract

The invention discloses a magnetic field enhanced plasma jet generation device, which belongs to the field of low-temperature plasmas, and comprises a plasma jet generation unit used for generating a plasma jet and outputting the plasma jet through a gas output pipeline of the plasma jet generation unit; the annular magnet is arranged on the outer side of the gas output pipeline in a surrounding mode and used for generating a magnetic field in the gas output pipeline, and the direction of Lorentz force provided by the magnetic field for the plasma jet is consistent with the flowing direction of the plasma jet so that the flowing speed of the plasma jet can be increased. The problems that an existing plasma jet is short in length, uneven in discharge and low in active component concentration are solved, the uniformity of dispersion and spatial distribution of the plasma is guaranteed, the concentration of active oxides in the plasma is enhanced, the contact efficiency of the products and processed objects in application is improved, and then the working efficiency of the whole device is improved.

Description

technical field [0001] The invention belongs to the field of low-temperature plasma, and more particularly, relates to a generating device for magnetic field-enhanced plasma jet. Background technique [0002] The atmospheric pressure low-temperature plasma jet is usually an ionization wave formed by the breakdown of the gas channel, because it occurs in an open space and is not restricted by a narrow air gap space, and is composed of electrons, ions, neutral particles and a variety of active radicals. The collection has great application potential in biomedicine, surface modification, nanotechnology and other fields. Dielectric barrier discharge is a common way to generate plasma jets, and it is widely used because it can generate large-area uniform plasma in a small gas gap. In order to improve the working efficiency of the plasma jet, on the one hand, it is devoted to the development of a plasma jet similar to the dispersion discharge of Townsend or glow under low pressur...
