摘　　要：本文介绍了160万t/a制酸生产线配套的循环冷却水系统的节能改造设计与实践,通过数据分析和现场调研确定了换热器循环水温度较高的主要原因,并定位了系统能耗浪费的主要环节。在此基础上通过更换填料等方式提升了冷却塔的热力性能,同时结合局部增压等供水手段降低了系统对于供水泵站流量和扬程的需求,最终取得了年节电340万度、节水50万t的显著效果。This paper introduces the design and practice of energy saving reconstruction of the recirculat-ing cooling system for a 1.6 million t/a acid-making production line.Through data analysis and field re-search,main causes of the higher temperature water in heat exchangers have been found,and the main points of system energy waste have been located.On this base,the thermal performance enhances after packing replacement,and the need for flow rate and head lift of pumps decreases due to the local pressur-ization method.Finally,the electricity saving and water saving have achieved 3.4 million kWh and 0.5 million tons per year,respectively.
