中文摘要: 维持进料量稳定，是保证碳酸化分解过程生产优化稳定的关键。但由于分解槽进料管较短、管径比较大、容易结疤。进料量难以用常规的过程检测仪表进行检测。本文建立了汇流的伯努利方程，总结出进料阀门的局部阻力系数与开度的关系，推导出高位槽液位、进料阀门及进料流量的函数关系，从而建立了进料流量的软测量模型。现场实验数据表明，进料流量软测量模型的预报精度在2．06％以内，可满足现场实际需要。
Abstract:It is very important for process optimization to maintain material flux steadily in the process. But it is difficult to measure material flux due to the short tube and scar of alumina solution. In this paper, after the function relation of parameter of local resistance and opening degree of the valve is discussed, the function of height of the high cell, opening degree of the valve and flux is deduced based on a conflux Bonuli formulation, and a soft-measurement method to compute materials flux is established. The practical result shows that the forecasting error is within 2.06% and can satisfy the practical application.
