Problems solved by technology

For example, some normal temperature and atmospheric pressure plasma sources have good sterilization and disinfection effects, while some normal temperature and atmospheric pressure plasma sources have better deodorization or dust removal functions, but it is difficult to have two or more effects

Abstract

The invention discloses an atmospheric pressure plasma gas generator of three electrodes and implementation method, the device comprises a dielectric barrier layer 3,a needle electrode 1 is positioned in the middle of the dielectric barrier layer 3, an metal outside electrode 4 is arranged on the outer layer of the dielectric barrier leyer3, an grid electrode 2 is arranged inside of the dielectric barrier layer, the grid electrode 2 is ring material with two open ends, an grid mesh electrode hole is arranged on the grid electrode 2; the method of generating the plasma gas comprises the following steps: an AC voltage signal is applied between the outer metal electrode 4 and the grid electrode 2, a surface micro discharge plasma gas is generated on the grid electrode, the atmospheric pressure plasma gas generator of three electrodes and implementation method has the advantages that two kinds different plasma gas are generated, therefore, the sterilization and deodorant function are obtained.

Description

technical field [0001] The invention relates to a gas generating device, in particular to a three-electrode normal temperature and atmospheric pressure plasma gas generating device using permanent magnets. Background technique [0002] Plasma is the fourth state of matter that is different from solids, liquids, and gases. The plasma states that we may come into contact with or learn about in our lives include the sun, lightning, plasma TV, light bulbs, and so on. Normal temperature and atmospheric pressure plasma is a special plasma form that has been developed internationally in the past 30 years. Such plasmas are at room temperature, can be touched by humans, are generated in an open atmosphere environment and generally have very good biomedically relevant properties. However, there are many methods for generating plasma at normal temperature and atmospheric pressure, and the generated plasma gas also has different functions correspondingly. For example, some normal temp...
