Abstract

The invention relates to a normal-pressure normal-temperature high-frequency water low-temperature plasma generator which comprises one or more than two electrodes. The electrode is inserted into an outer insulation tube through an inner insulation tube with the inner wall coated with a conductive film, the distance between the inner wall of the outer tube and the outer wall of the inner tube is not larger than 5 mm, an air uniformizing chamber is arranged on the upper portion of the outer tube and can be placed underwater or exposed out of the water face, a ground terminal of an output pole of an alternating current power supply is inserted into liquid, the other pole of the alternating current power supply is connected into a conductive layer of the inner tube, the potential difference of the two poles is not smaller than 1 KV, and the frequency ranges from 1 KHz to 50 KHz. Low-temperature plasma meeting the industrialization requirement can be generated continuously and stably, organic matter and other toxic and harmful substances in water are directly decomposed and treated, the water reaches the standard, no chemical is added, and no toxic or harmful by-product is generated after treatment. The electrode can be directly placed in the treated water, occupied space is small, energy consumption is low, the early investment cost and running cost are low, and the advantages of being efficient, saving energy and being environmentally friendly are achieved.

Description

technical field [0001] The invention relates to a normal-pressure, normal-temperature, high-frequency water body low-temperature plasma generator. Background technique [0002] There are three methods for generating low-temperature plasma related to liquids: one is to provide a liquid point in the gas-phase discharge space; the other is to discharge at the gas-liquid interface; the third is to discharge in the liquid. [0003] The low-temperature plasma currently used in industrial production is not generated in water bodies, and the existing low-temperature plasma generators in water bodies cannot continuously generate a large amount of stable low-temperature plasma for a long time, and produce low-temperature plasma in water bodies The difficulty and cost of the special ultra-high voltage power supply required also hinder the commercial production of low-temperature plasma in water. [0004] Patent No.: 200880007335.9 provides a low-temperature plasma generator. For the ...
