采用相似原理指导下的水模型实验,研究新型阴极结构电解槽中阳极气体的扰动.通过高速摄影手段拍摄液面波动,得到不同操作条件下阴极结构铝电解槽水模型的液面波动图像,利用Image-Pro-Plus6.0专业图像分析软件对捕捉到的波动静态图进行处理,获得液面波动的最大高度.并用Fluent6.2.16进一步对电解槽的阳极结构进行数学模拟.结果表明,极距的增加、电解质水平的提高、气体流量的减小,均会减小界面波动.新型阴极结构电解槽比普通阴极结构阳极气体引起的界面波动小,新型阴极结构可有效地降低极距;相同实验条件下,1/2阳极产生气体引起的界面波动振幅和普通阳极没有明显区别,而1/4阳极的减波作用较好,倒角对于界面波动的影响甚微.
The water model experiment under the principle of similar principle was used to study the disturbance of anode gas in the novel cathode structure electrolysis cell.Using high-speed photographic method to capture the liquid surface fluctuation, the liquid surface fluctuation images of the cathode model aluminum electrolyzer under different operating conditions were obtained, Image-Pro-Plus6.0 professional image analysis software to capture the static wave chart to deal with fluctuations to obtain the maximum height of the liquid level fluctuations and Fluent6.2.16 further electrolysis cell anode structure of the mathematical simulation results show that pole pitch Increase, the electrolyte level increases, the gas flow rate decreases, will reduce the interface fluctuations.The new cathode structure of the electrolytic cell than the ordinary cathode structure of the anode gas caused by small fluctuations in the interface, the new cathode structure can effectively reduce the polar distance; the same experimental conditions , There is no obvious difference between the amplitude of the interface fluctuation caused by 1/2 anode gas generation and that of the normal anode. However, the effect of the 1/4 anode anode wave reduction is good, and the chamfer has little effect on the interface fluctuation.
