这是一个等离子体反应器的设计及其电气和流体力学性能的基础研究。在这项研究中，适用于这种方法的电极结构和它在反应器中的安装位置进行了检查。该结构使用陶瓷管和不锈钢棒，使其能够使用高电导率水。测量反应器内的压力，并将电极放置在空化最小的位置。然后，在电导率约为10 mS m-1的水样品中观察到空化，并且还观察到等离子体。发现电极之间的总功率输入的约20%用于等离子体产生。观察到过氧化氢浓度与输入功率成比例，并且当水的体积为1.8l时，在20 W的输入功率下获得约5.5mg l-1的浓度。H2 O2的发电量为5.9 g kWh− 1。
This is a fundamental study on a design of a plasma reactor and its electrical and hydrodynamic properties. In this study, the electrode structure suitable for this method and its installation position in the reactor were examined. The structure uses a ceramic tube and a stainless steel rod, making it possible to use high conductivity water. The pressure inside the reactor was measured, and the electrode was placed at a position where cavitation was minimum. Then, the cavitation was observed in a sample of water with a conductivity of about 10 mS m− 1, and the plasma was also observed. It was found that about 20% of the total power input between the electrodes was used for plasma generation. The hydrogen peroxide concentration proportional to the input power was observed, and a concentration of about 5.5 mg l− 1 was obtained at an input power of 20 W when the volume of water was 1.8 l. And also the energy yield of H 2 O 2 generation was 5.9 g kWh− 1.
