摘要 以Linnhoff换热网络夹点技术理论为基础,提出了在进行换热网络设计时,考虑热容流率随温度发生变化时确定夹点位置的方法,并结合实例进行分析计算。该法对夹点位置、最小温差、公用工程用量的确定更加准确,对投资费用的估算也更接近于实际。 Based on Linnhoff pinch technology, a method of locating the pinch which considers the heat capacity flowrate of a stream with variation in temperature is presented for the design of heat exchanger networks. It is analyzed and calculated in combination with an practical example. The result shows that the pinch position, the minimum temperature difference and utility consumption can be determined more accurately. The investment estimate is more close to the actual situation.
