Low-temperature plasmatron with double spiral electrodes

Abstract

The invention provides a low-temperature plasmatron with double spiral electrodes. The plasmatron comprises a wide-pitch external spiral wire electrode, a spacing-free internal spiral wire electrode and a tubular insulator, the wide-pitch external spiral wire electrode is wound around the tubular insulator, and the spacing-free internal spiral wire electrode is positioned in the tubular insulator.The electrodes are avoided from oxidation and aging, a gap is not generated in the inner wall of the tubular insulator, a conducting performance is stable, the output is improved greatly, a production and manufacture process is less difficult, the intensity of the tubular insulator is improved, and the reject ratio in the production and processing process and fragmentation and damage during transport and use are reduced.

Description

technical field [0001] The invention relates to a low-temperature plasma generator, in particular to a double-helix electrode low-temperature plasma generator. Background technique [0002] Low-temperature plasma ozone generators often utilize pairs of electrode elements facing each other. For example, it can be known from patent document A that the patent number is "CN200880007335.9" and the patent name is "low-temperature plasma generator": in order to prevent rod-shaped conductors from being used as discharge electrodes in The heat generation and power consumption caused by the space gap formed when the tubular insulator is inserted, the patent document does not use a rod-shaped conductor. On the other hand, by enclosing the conductive paste in the space provided in the insulator, no space gap will be formed on the inner surface of the space provided in the insulator. Thereby, various problems due to the gap can be solved, and the effect of improving the ozone generation...

AI Technical Summary

Problems solved by technology

[0003] The conductive performance of the resin component of the conductive paste is affected by the process such as the amount of metal powder added and the uniformity of modulation, and is not as stable as the metal electrode. Since the two stages are parallel, the length of the effective discharge to produce ozone is two parallel straight lines. The length is determined by the length. In the manufacturing process, the length will limit the output. Since the amount of ozone produced is closely related to the distance between the two electrodes, the slight changes in the parallelism of the two electrodes and the accuracy of the distance between the two electrodes will directly affect the product quality and ozone. Therefore, the manufacturing process is more difficult, and the rate of defective products will increase. Since the glass or ceramic tubular insulator is fragile, and the soft conductive paste filled inside cannot enhance its strength as an electrode, the reject rate will increase during the production process. Easy to break during lifting, transportation and use
