基于杂质赤字的再生回用水网络集成图示法
|
摘要
将氢网络中基于剩余率的集成优化法扩展至水网络,以杂质浓度为基础进行分析,提出了基于杂质赤字的再生回用水网络图像集成优化方法。该方法无需图像试差和迭代,通过构建浓度-流量图和杂质赤字图,可确定未考虑再生回用的水网络夹点位置及最小新鲜水用量。并在此基础上,考虑再生装置和水网络的优化以及二者的集成,分析水网络的新鲜水节省量与杂质脱除率、再生水源流量及再生废水浓度的定量关系;构建定量关系图确定最小新鲜水用量随各参数的变化关系、夹点位置、最大新鲜水节省量以及一定再生条件下的极限及最优提纯参数。案例分析表明,该方法简单、高效,对于各工况下的水网络,均可使新鲜水消耗量及废水排放量减小,为工艺设计和操作提供重要的参考。
The hydrogen network integration and optimization method was extended to the water network,based on hydrogen surplus and the conceptual integration method. Through analyzing impurity concentration, an impurity deficit graphical integration and optimization method was proposed for water network with regeneration reuse, which did not require trial and iteration. For the water network without regeneration reuse, the position of the pinch point and the minimum fresh water could be identified by constructing concentration-flowrate diagram and impurity deficit diagram. Furthermore, for the water network with regeneration, the relation between the fresh water consumption saving and impurity removal rate, regenerated water flowrate and concentration was deduced. The diagram was developed to identify the variation of fresh water consumption along these parameters, the location of the pinch point, the maximum fresh water savings, the limiting and the optimal regeneration parameters under a certain conditions. Case study shows that this method is simple and efficient, and can be applied to reduce fresh water consumption and wastewater discharge for different operating conditions, as well as provide important reference for process design and operation.
