摘要:基于浆料洗涤系统的整体工程思想,对洗浆系统和蒸发系统进行了物料衡算，建立了纸浆洗涤用水和稀释因子的最优化模型,并通过罚函数,将约束问题转化为无约束问题,对模型进行了寻优控制。实践表明,该方法可以找到最优稀释因子,减少了费用,降低了生产成本。

Abstract:The purpose of the optimal control of pulp washing is not only to ensure the quality of pulp washing, but also to reduce the energy consumption. Water is one of the most important resources; reduce water consumption is to reduce energy consumption. This paper analyzed the material balance in pulp washing and evaporation. The model related dilution factor and washing water was established, the model was optimized by penalty function, which can turn the constrained problem into unconstrained. It showd that the method can find the optimal dilution factor, reduce the consumption, bring greater economic benefits to the enterprises.
