摘要
本文采用数值模拟和工业测量手段对国内某大型铝电解槽内的氧化铝浓度分布情况进行分析,数值模拟仿真和工业测试分析均显示出铝电解槽烟道端半槽的平均浓度高于出铝端半槽的平均浓度。研究发现电解质的流动模式是造成这种差异的主要原因,这可以为现有电解槽氧化铝控制的进一步优化提供有价值的参考依据。
The alumina concentration distribution in domestic large-amperage prebaked aluminum reduction cells was analyzed in this paper through the numerical simulation and industrial measurement.Both the numerical simulation and measurement results showed that the average alumina concentration in the half cell closed to Duct-end was higher than that in the half cell near Tap-end.This research showed that the bath flow pattern was the main reason behind such differences,which could provide some valuable reference information to further optimize the existing alumina control in reduction cells.
