Technical Field

The invention relates to the technical field of low-temperature plasma tubes, in particular to a novel structural silver-based graphene multi-medium low-temperature plasma tube.

Background

The high-energy ion tube is used for generating positive and negative ions, is widely applied to deodorization equipment and air purification equipment, is a main functional accessory of the deodorization equipment and the air purification equipment, and has the working principle that the continuous discharge on the surface of a glass tube is realized by utilizing the corona working principle of a medium. Oxygen molecules in the air are loaded with positive and negative charges by a special ionization tube through a corona discharge principle and generate a magnetization effect to generate specific ion clusters, each ion cluster at least consists of hundreds of even hundreds of thousands of independent oxygen atoms which are connected in series, and the ion clusters with extremely high oxidizability surround harmful substance molecules, peculiar smell molecules, bacteria, mildew, viruses and the like in the air to decompose or lose activity, so that the effects of purification, sterilization and extinction are achieved.

Surface discharge means that when there are some linear small radius of curvature electrodes around the insulating medium, it will produce an asymmetric electric field distribution near the electrodes, while corona and discharge along the dielectric surface will occur on the dielectric surface near the electrodes, which will enable a more uniform plasma because the surface discharge action sites are limited to the surface and therefore more dense. To achieve discharge, an alternating current must be applied across the electrodes, a direct current cannot pass through, and the electric field strength must be high enough to cause gas breakdown. The material of the dielectric barrier is generally glass or quartz glass, in special cases ceramics may also be used, as well as thin enamel or polymer layers. Under the action of high-voltage alternating current, the traditional high-energy ion tube is easy to have the phenomenon of electrode contact point ablation, and the condition that the service life of the high-energy ion tube is reduced because nitrogen oxide is accumulated on the surface of a dielectric barrier layer due to air in an ionization tube on the inner wall of the dielectric barrier layer.
