UNDERWATER CAPILLARY TUBE PLASMA DEVICE HAVING GAS CHANNEL

摘要

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.
