Abstract

The invention discloses an atomizing cold plasma jet generation device, which comprises a gas supply system, an atomizing system, a high-voltage power supply, a cold plasma jet generation device and acylindrical outer shell, wherein the cold plasma jet generation device is mounted in the cylindrical outer shell, and the cold plasma jet generation device and the cylindrical outer shell are coaxial; the gas supply system inputs working gas into the cold plasma jet generation device from the tail part; the high-voltage and low-voltage output ends of the high-voltage power supply are connected with electrodes of the cold plasma jet generation device; the atomizing device inputs atomized liquid into the interior of the cylindrical shell; when the cold plasma jet generated by the cold plasma jet generation device is ejected, negative pressure is generated inside the cylindrical outer shell, the atomized liquid is introduced into the cylindrical outer shell and is mixed with the cold plasmajet to form the atomized cold plasma jet, and the atomized cold plasma jet is ejected at an outlet of the cylindrical outer shell. Uniform and stable atomized cold plasma jet is obtained by the atomizing cold plasma jet generation device, and the hydrophilic modification effect of the plasma on the solid surface and the cooling and lubricating effects of the cutting contact area in the cutting process are favorably improved.

Description

technical field [0001] The invention relates to an atomized cold plasma jet generator, which belongs to the technical field of plasma discharge reactors. Background technique [0002] The macroscopic temperature of cold plasma is not high, but the ratio of electron temperature to gas temperature is about 10 to 100 to 1, so it also has high chemical activity: it is rich in a large number of ions, electrons, excited state atoms, molecules and Active particles such as free radicals have more types and stronger activity than those produced in common liquid and gas chemical reactors, and are easy to react with the surface of the material they are in contact with. Therefore, in recent years, cold plasma has been widely used in sterilization, ozone synthesis, solid film deposition, surface modification (improving the water absorption, conductivity, adhesion, printing and dyeing and wettability of films, paper, textiles and fibers), Plasma etching, device cleaning, air pollution tr...
