摘要/Abstract

摘要： 采用混合节点和分配节点的概念,建立了多级闪蒸(MSF)和反渗透(RO)海水淡化集成系统的超结构模型,以年度总费用最小为目标,引入产水比的概念,并将该参数作为集成系统的一个优化变量,采用改进的遗传算法进行求解,获得了集成系统的最优结构及相应的操作条件。实例结果表明:集成海水淡化系统的淡水成本比独立运行的RO和MSF低,产水比为0.45时集成系统的费用最小,流程结构为MSF-RO。

Abstract: It is accepted in the world that the quality and the quantity of desalination could be improved under the hybrid desalination system,at the same time the energy cost would be decreased greatly.The superstructure model of hybrid multistage flash(MSF)/reverse osmosis(RO)desalination system is presented based on the blend note and the distribution note which aims to minimize the total annual cost.The ratio of RO and MSF product rate R is introduced as an optimum variable.The modified genetic algorithm(MGA)is adopted to solve the problem and the optimum structure and the operation condition are obtained.The results showed that the cost of water of hybrid desalination system is lower than that of the independent MSF and RO.The optimal value of R is 0.45 for the example and the optimal configuration is MSF-RO.

Key words: coupling of RO and MSF, desalination, system integration, optimum design
