摘要/Abstract

摘要： 铝电解槽阳极气泡行为对工艺参数敏感，因此，采用透明电解槽研究阳极倾斜和阳极倒角对气泡析出行为的影响.结果表明:当阳极倾斜度较小(小于2°)时，倾角的变化对气泡行为影响较小;当阳极倾斜度大于2°时，阳极倾斜角的增加会明显加速气泡运动速度但减小气泡尺寸和覆盖率;在倾斜阳极上观测到类似“Fortin”气泡;阳极倒角会一定程度减小气泡尺寸和覆盖率，但对加快气泡脱离速度的作用并不显著.

关键词: 铝电解, 透明电解槽, 倾斜阳极, 倒角阳极, 气体排出

Abstract: The behavior of anodic bubbles in the aluminum electrolytic cells is sensitive to the electrolysis parameters. So， transparent electrolysis cells are used to study the effects of inclined anode and rounded anode on the bubble behavior in a similar environment used in industrial cells. The results show that when the inclined angle is below 2°， the change in angle has little effect on bubble behavior， and when the inclined angle is above 2°， the bubble velocity increases significantly and the bubble size and coverage ratio decrease with the angle increasing. Moreover， "Fortin"-like bubbles are observed on the inclined anodes. The rounded anode reduces the bubble size and coverage ratio at a certain degree， while it does not promote bubbles releasing obviously.

Key words: aluminum electrolysis, transparent electrolysis cell, inclined anode, rounded anode, bubble releasing
