【摘要】 本文采用一种新的冷却塔水循环系统优化方案,将冷却塔水循环系统中循环水与流股数同时最小化的多目标优化问题分解成多步的单目标优化问题。分别以最小循环水量和流股数为目标,建立了优化数学模型,并在模型中引入了松弛常数,以增加循环水网络设计的柔性。对比文献实例的优化结果,采用本文方法能在循环水量目标值相同的条件下,得到结构简单的水网络。此外,用实例说明,通过调节流量松弛常数,能进一步优化水网络结构。更多还原

【Abstract】 A new approach was proposed for the optimization of water networks: the multi-objective minimization of cooling tower water system, recycled water and the number of streams through decomposition into single-objective optimization. By having the least recycled water and number of streams as the objectives, a mathematical model of the water network was established and implemented on a practical example. The resulting water network had the least recycled water and stream system which was very economical. The water network was also flexible and less complex.更多还原
