摘　　要：结合当前水资源短缺形势的日益严峻,对工业中热物流温度差别大、水冷器数量多的循环冷却水系统进行了优化研究,并引入新的优化方案,即水冷器网络采用多级中间水道的系统结构。总结出多级中间水道的设计规则,并在此结构下考虑水冷器、冷却塔等装置的设备投资,建立包括设备费用和操作费用的数学模型,确定系统的运行方式。经过实例验证可知,系统中水冷器网络采用多级中间水道后的运行费用明显减少,所建数学模型行之有效。Considering more and more serious situation of water resource shortage, a new optimization scheme for circulating cooling water system with more water coolers and big temperature difference of hot process stream is introduced,in which water cooler network structure adopts multistage intermediate coolingwater mains. The design rules of multistage intermediate channel are summarized. The equipment investment of water coolers and cooling tower is taken into account. A mathematical model of circulating cooling water systemincluding capital cost and operating cost is established. The optimal operation mode is eventually confirmed. The experimental results show thatthe running cost of circulating cooling water system is significantly decreased and the mathematical model is effective.
