摘　　要：针对冷凝脱湿的特性,利用能效分析法、物料平衡法和热力平衡法建立了高炉鼓风系统冷能利用的分析模型.对某钢厂的高炉鼓风冷却脱湿系统的实际数据进行整理归纳并利用该模型进行计算分析,结果表明:该钢厂高炉鼓风脱湿系统的冷能利用不充分.为提高冷能利用,盛夏月份每日产生的22.56T/h、10℃冷凝水量,经处理可以回收利用到单台冷冻机的冷凝器,降低冷凝器侧循环冷却水温度1℃,增强了冷凝器换热效果和制冷系统制冷量352kW,提高了高炉鼓风脱湿系统的冷能效用.According to the characters of condensing dehumidification, the energy efficiency method,material balance method and heat balance method were used to build-an analytical model about the cascade use of cooling energy in blast furnace （BF） blower system. The actual data, which were collected from a steel-works, were settled and then analyzed by means of the analytical model. The results show that the cooling energy in the steel-works＇ BF blower dehumidifying system is not fully used. For better use,the condensed water,with a production rate of 22.56 tons an hour at 10 ℃in July and August, can be used in the condenser of one refrigerator after water treatment, and lower the cooling water temperature by 1 ℃ Meanwhile, it can enhance heat transferring and increase the cooling energy of refrigerating system by 352 kW.
