Abstract:
Disclosed is an underwater capillary tube plasma device having a gas channel. According to one embodiment of the present invention, an underwater capillary tube plasma device comprises: a power supply unit which supplies power; a discharge electrode which receives power supplied from said power supply unit, and induces a capillary tube plasma discharge inside a fluid; and a gas supply unit which injects auxiliary gas into said discharge electrode. According to the embodiments of the present invention, since a gas channel is equipped in an underwater capillary tube plasma discharge electrode, various chemical reactive species are created according to the injected gas, including plasma species which are created from water decomposition caused by a plasma discharge, whereby underwater pollutants are effectively removed. In addition, if the gas is injected like in the present invention, the concentration and the lifetime, within a fluid, of the reactive species which are created by the plasma discharge are increased such that a purification effect by plasma can be maximized. Further, if such auxiliary gas is supplied, plasma can be generated even by a lower power supply compared with when the gas is not injected, thereby reducing energy consumption for fluid purification.

Abstract:
The present invention relates to an antenna of a novel construction for generating a uniform and large-area plasma by using microwaves, and the microwave antenna for generating plasma of the present invention comprises a waveguide, an antenna main body, and a connecting part of coaxial construction for electrically connecting the waveguide and the antenna main body; wherein the antenna main body consists of a doughnut-shaped electrical conductor block formed with a plurality of slots, recesses are formed between the plurality of slots in the electrical conductor block, and a plurality of permanent magnets are inserted in the recesses. The plurality of slots can be formed passing through inner and outer parts of the electrical conductor block, and the plurality of slots can be formed so as to repeat in a square-wave shape. The present invention has the advantageous effect that a plasma can be generated which has uniform symmetry of uniform large area because the permanent magnets are mounted directly on the antenna itself, hot electrons (energetic electrons) produced by means of ECR pass through and are distributed by the microwave antenna as a whole due to a force caused by magnetic field gradient and curvature, and the hot electrons again ionise the surrounding neutral particles.
