摘要
研究了求解有额外蒸汽引出的并流多效蒸发淡碱浓缩工艺数学模型的一种新算法———矩阵法 ,利用可视化语言VisualBasic 6 0编制了淡碱多效蒸发浓缩的计算程序。新算法优于目前已有的各种多效蒸发工艺计算方法 ,具有对初值要求不高、收敛稳定性好、收敛速度快等优点。算例表明 ,引出额外蒸汽预热淡碱节能效果显著。
The model of cocurrent multi-effect evaporation with extra steam being led off is established for the concentration of sparse sodium hydroxide solution.A new algorihm of matrix method is studied.The new algorithm is more effective than the others that can be provided at present about multi-effect evaporation technology.It shows that the extra steam being led off to preheat the sparse NaOH solution can save the cost remarkably.
