Embodiment 1

[0031] Such as figure 1 As shown, a large-volume honeycomb corona plasma 3D uniformity adjustment device includes a first flat structure 1, an adjustable length adjustment needle 2 is arranged on the end surface of the first flat structure 1, and the adjustment needle 2 is perpendicular to The first plate structure 1, the number of the adjustment needles 2 is several, and the electrode needles 3 are arranged around each adjustment needle 2, the number of the electrode needles 3 is six, and the distance between the six electrode needles 3 and the adjustment needles 2 is equal , the electrode needles 3 are perpendicular to the first plate structure 1, the six electrode needles 3 form a honeycomb unit, and each two adjacent adjustment needles 2 share two of the six electrode needles 3, and all the electrode needles 3 form The honeycomb multi-needle electrode, the first flat plate structure 1, the honeycomb multi-needle electrode and the regulating needle 2 form a combined dischar...

Embodiment 2

[0034] This embodiment is carried out on the basis of Embodiment 1. The present invention mainly consists of a honeycomb multi-needle electrode composed of electrode needles 3, an adjustable effective length regulating needle 2 in the center of the honeycomb unit, and a first flat structure 1.

[0035] Among them, the honeycomb multi-needle electrode structure is composed of corona needles, such as figure 2 shown. Among them, the material of the corona needle is tungsten, which mainly takes advantage of the high melting point and stable chemical properties of the metal tungsten material to ensure that the corona needle can be used repeatedly. The base material is aluminum, which plays the role of support and electrical connection.

[0036] The function of the adjusting needle 2 with adjustable effective length in the center of the honeycomb unit mainly depends on the retractable fixing hole on the first flat structure 1 to adjust the length of the adjusting needle 2 protrudi...

Abstract

The invention discloses a large-volume honeycomb corona plasma 3D uniformity adjusting device, and the device comprises a first panel structure, wherein an end face of the first panel structure is provided with a honeycomb-shaped multi-pin electrode composed of electrode pins. The electrode pins are perpendicular to the first panel structure, and the connection lines between the electrode pins andthe contact point of the first panel structure form a regular hexagon, wherein the center of the regular hexagon is provided with an adjustment pin with the adjustable length. The adjustment pin is perpendicular to the first panel structure, and the first panel structure, the honeycomb-shaped multi-pin electrode and the adjustment pin form a discharge combined electrode. The device provided by the invention can generate a large-volume corona plasma under a lower voltage, can adjust the size and shape of the corona plasma in a three-dimensional range, enables the corona plasma to better applyto the industrial production and scientific research.

Description

technical field [0001] The invention relates to the field of plasma discharge, in particular to a large-volume honeycomb corona plasma 3D uniformity adjustment device. Background technique [0002] As the fourth state of matter after solid, liquid, and gas, plasma is widely used in lighting, welding, smelting, etching microfabrication, and surface treatment and modification. [0003] At present, there are various forms of plasma reactors, which can be divided into line-barrel type, line-plate type, pin-plate type and so on according to different structures. Compared with other plasma reactor structures, the pin-plate electrode structure studied in this paper has the following advantages: [0004] 1) Low corona onset voltage; [0005] 2) High spark breakdown voltage; [0006] 3) Good discharge stability. [0007] Its disadvantage is that the electric field distortion is the most serious only near the needle electrode, and only a limited number of strong discharge points c...
