摘要
为研究多粒子间的相互关系,使研究中的粒子状态更加接近实际体系,实验将多个模拟粒子以串联方式放置在电解槽主极板垂直方向上,分别测定了1～3个1 cm粒子、1 cm粒子＋1～3 cm粒子时各粒子的粒子电流和虚拟槽电压.结果表明：在主极板电压相同时,随模拟粒子数量的增加,粒子的电流和两端虚拟槽电压明显减小,粒子之间相互影响较大;充填粒子的加入会减弱原模拟粒子的电化学反应速率,且加入的粒子越大,对原粒子的影响越大;随着粒子粒径的增大,粒子两端虚拟槽电压随之增大,粒子电流也增大,不同大小的粒子串联加入电解槽装置中时,各粒子电流并非等效串联关系.在电化学反应器中,粒子之间受数量、大小、间距等影响明显,粒子充填量存在一个最佳填充比.
Aimed at studying the relationship between multi-particles and making the particles in the state closer to the actual system in the three-dimensional electrode system,multiple analog particles were placed in the vertical direction of two main plates,and the particle currents and the virtual slot voltages were determined when there were 1-3 cm particles or 1 cm＋1-3 cm particles respectively.The results show that the particle currents and the virtual slot voltages are reduced significantly with the increasing number of simulated particles in the same main plate voltage,in which the particles are affected by each other greatly; the electrochemical reaction rate of the original analog particles is weakened by the new filling particles,and as the size of the filling particles is larger,the impact will be greater; both the virtual cell voltage and the particle current are reduced with the increasing of the number and the size of the filling particles in the three-dimensional electrode system,and the particle currents between different sizes are non-equivalent when a series of different size particles are added to the electrolytic cell unit.The particles are affected each other obviously by the number,size and spacing of the particles,and the filling volume of the particles exists an optimum filling ratio in the electrochemical reactor.
