【摘要】 建立了一个二维瞬态数学模型，分别描述了水平电极稀土电解槽中阳极气泡动力学和气泡诱导的电解液运动。结果表明，随着阳极倾斜角度的增大，阳极气泡厚度逐渐增大。此外，与常规阳极相比，倾斜和倒角阳极有利于缩短气泡长度，提高气泡速度。同时，电解槽内气泡诱导的电解质运动可以改善稀土氟氧化物的分布和运动过程，从而提高电流效率。最后，基于电解液流动提出了一种新型的加料方式。更多还原

【Abstract】 A 2D transient mathematical model was established to separately describe the anode bubble dynamics and the bubbleinduced electrolyte motion in the rare earth electrolysis cell with horizontal electrode. Results indicate that with the increase in the anode inclined angle, the maximum bubble thickness is increased gradually. Furthermore, compared with the conventional anode, the inclined and chamfered anodes are conductive to the bubble length reduction and the bubble velocity improvement. Meanwhile, the bubble-induced electrolyte motion in the electrolysis cell can improve the distribution and transport process of oxyfluorides, thereby enhancing the current efficiency. Finally, a novel feeding method based on the electrolyte flow is proposed.更多还原
