Abstract

The invention provides an atmospheric pressure large-area uniform space plasma generating device. The atmospheric pressure large-area uniform space plasma generating device comprises dielectric plates, dielectric tubes, metal electrodes and wires. Each dielectric plate is formed by sequentially connecting four insulating substrates, wherein holes are formed in the surfaces of the two long-plate-face insulating substrates, and the holes are staggered. The dielectric tubes are inserted into the holes of the long-plate face insulating substrates on one side to groove holes in the inner surfaces of the long-plate-face insulating substrates on the other side, the dielectric tubes are sealed and fixed in the holes through sealant, and the closed ends are inserted into the groove holes of the long-plate-face insulating substrates on the other side and fixed in an adhesion mode. The metal electrodes are inserted into the dielectric tubes, one end of each metal electrode is connected with the bottom of the corresponding dielectric tube, and the other end of each metal electrode stretches out of the corresponding dielectric tube. The metal electrodes in the dielectric tubes on one side serve as high-voltage electrodes which are connected through the corresponding wire and then connected with a high-voltage power source, the metal electrodes in the dielectric tubes on the other side serve as ground electrodes which are connected through the corresponding wire and then grounded, and high-voltage access ports of the metal electrodes in the dielectric tubes on one side and ground electrode access ports of the metal electrodes in the dielectric tubes on the other side are connected in a diagonal mode. The atmospheric pressure large-area uniform space plasma generating device has the advantages of being stable in discharge, high in adjustability, safe, reliable and the like.

Description

technical field [0001] The invention relates to a plasma generating device, in particular to a device capable of generating large-area uniform space plasma in space under the condition of atmospheric pressure. Background technique [0002] At present, plasma is widely used in industry and agriculture, and has the function of sterilization or deodorization. It is known that there are many kinds of plasma generators in existence, and most of them adopt the method of inserting a dielectric plate or a dielectric sheet between two conductive substrates, forming a dielectric film on the opposite surface of the conductive substrate, and forming a dielectric film on the two substrates. A plasma discharge occurs in the gap between them. [0003] However, most of the current plasma generators have the problem of unstable discharge, and it is difficult to adjust the distance between the dielectric tubes. Contents of the invention [0004] The purpose of the present invention is to ...
