Abstract

An underwater capillary plasma device with a gas channel is provided. The underwater capillary plasma device includes a power supply unit configured to supply power, a discharge electrode configured to receive the power supplied from the power supply unit and cause capillary plasma discharge in a fluid, and a discharge electrode configured to inject an assist gas into the discharge electrode. Gas supply unit. Since the underwater capillary plasma device is equipped with gas channels, plasma species can be generated from water decomposition caused by plasma discharge, and various chemical reaction species can be generated according to the injected auxiliary gas, thereby effectively removing underwater pollutants . In addition, when gas is injected as described herein, the concentration and lifetime of the reactive species in the fluid produced by the plasma discharge can be increased and extended, thereby maximizing the effectiveness of purification using the plasma. Furthermore, when the assist gas is supplied as described above, plasma can be generated even by a smaller power supply than when the assist gas is not injected, thereby reducing energy consumption for purification of the fluid.

Description

technical field [0001] The present invention relates to an underwater capillary plasma device, in particular to a technique for effectively purifying sewage by equipping an underwater capillary plasma discharge electrode with a gas channel. Background technique [0002] In recent years, research on various methods has been conducted for purification of sewage and removal of bacteria. For example, these methods include a method using ozone, a method of adding chemicals such as hypochlorous acid (HClO) to sewage, a method using ultraviolet rays, a method using heat treatment, and the like. [0003] However, such methods have problems in that effective purification performance of the method cannot be obtained, excessive costs may be required to dispose of sewage, or unexpected side effects may be caused. Accordingly, there is an increasing need for methods of effectively purifying sewage and removing microorganisms such as bacteria. Contents of the invention [0004] techni...
