本文论述了工厂企业的节能过程和余热回收利用途径,着重介绍了分析生产工艺用能的热利用线图法。对余热动力回收的温限范围和工质进行分析研究之后.指出:余热源在600℃以上,可使用水和蒸汽工质;在300～600℃之间,宜用低沸点有机工质;在300℃以下,以热利用为宜。最后,本文还分析了总能热泵的节能作用。
This article discusses the energy-saving process and waste heat recovery and utilization of factory enterprises, and emphatically introduces the heat utilization diagram of analyzing the energy consumption of the production process. After analyzing and analyzing the temperature-limited range and working fluid recovery of residual heat power, it is pointed out that the residual heat source can use water and steam working fluid above 600 ℃, low boiling point organic medium between 300 and 600 ℃, 300 ℃ the following, to heat use is appropriate. Finally, this article also analyzes the energy-saving effect of the total heat pump.
