A Spliced ​​Honeycomb Electric Field Structure for Dielectric Barrier Discharge

Abstract

A spliced ​​honeycomb electric field structure for dielectric barrier discharge, including a shell, tubular electrodes and wire electrodes. The tubular electrodes are in a regular hexagonal structure and arranged in a honeycomb shape. In the center of the tubular electrode, the wire electrode and the tubular electrode are separated by insulating material; the tubular electrode is composed of parts assembled, and the parts include a honeycomb plate 6 and a connecting piece 7, and the honeycomb plate 6 is detachably connected to each other through the connecting piece 7; inside and outside the tubular electrode The surface is attached with an oxide film by anodic oxidation. The honeycomb electric field of the present invention is assembled by honeycomb panels and connectors. The splicing method is very simple and can be quickly installed or disassembled. The surface of each component is anodized to form an oxide film, so that there is an oxide film between the wire electrode and the tubular electrode. The two layers of dielectric and air achieve the effect of double dielectric barrier discharge, increase the effective range of discharge area, and improve the space utilization rate.

technical field [0001] The invention relates to the technical field of exhaust gas purification devices, in particular to a spliced ​​honeycomb electric field structure of dielectric barrier discharge. Background technique [0002] Dielectric Barrier Discharge (DBD) is an atmospheric pressure low temperature plasma technology with good application prospects discovered in the 1860s. Because dielectric barrier discharge has the advantages of small structure, simple structure, less energy consumption, relatively mild reaction conditions, and strong excitation ability in the same field of instruments, this technology is widely used in battery materials, environmental Pollutant removal, spectral analysis applications, and other industrialization and laboratory research fields, such as ozone synthesis, CO2 lasers, UV light sources, environmental treatment, air purification, surface treatment, material modification.

AI Technical Summary

Problems solved by technology

If the tubular body is made of aluminum alloy, the surface is often treated by anodic oxidation, but this method can only attach an oxide film on the outer surface of the aluminum alloy tubular body, and the treatment of the inner surface of the aluminum alloy tubular body It is more difficult. When these aluminum alloy tubular bodies are used to form a honeycomb electric field, a good dielectric barrier discharge condition is formed only between two adjacent tubular bodies. The dielectric barrier discharge phenomenon inside the aluminum alloy tubular body is not ideal, so , it is necessary to improve the structure of the honeycomb electric field, so that the inner and outer surfaces of the aluminum alloy tubular electrodes can be easily treated to add a dielectric layer, and a good dielectric barrier discharge condition can be formed between the interior of the tubular electrode and the adjacent tubular electrodes. Improve the work processing efficiency of equipment
