为探究三维电极在实际应用中的影响因素,构建了电解槽的模型装置.实验采用自制的有机玻璃电解槽,阳极板选用Ti/RuO2-IrO2,阴极板选用1Gr18Ni9Ti.用一对钛平板电极作为模拟粒子,通过改变主极板电压和粒子间距来测量粒子电流、虚拟槽电压和主极板电流,研究粒子电流的影响因素.实验结果表明,主极板电压和模拟粒子间距是影响粒子电流的主要因素,在电压一定的情况下,模拟粒子电化学反应产物的增加以及主极板电化学产物的增加产生了一个综合效应,三维电极电化学反应器比二维电极电化学反应器能量效率高.

Aiming at studying the influence factors and enriching the research content of working principle in the three-dimensional electrode system, cell model device was established. In the experiment, the self-made organic glass cell was used, the positive plate of Ti/RuOE-IrO2 and the negative plate of 1GrlSNi9Ti were selected. The particles were simulated by two small Ti plate electrode. The particle current, the virtual cell voltage, the current of the main plates were measured by changing the interparticle distance and the voltage of the main pole plates respectively. Then the influence factors of the particle current were analyzed through the experimental data. The results show that the particle current is mainly influenced by the voltage of the main pole plates and the distance of the simulated particle; the energy efficiency of the three-dlmensional electrode electrochemical is higher than the two-dimensional under the certain voltage circumstances, which is generated by the increasing of electrochemical reaction product including the filling particles and the main pole plates.
