空气压缩机长时间工作时，排气温度往往高达85℃~102℃，这里蕴藏着大量的热能，这部份热能在未被利用之前，被称为废热，被风扇或冷却水带走，排放于周围环境中，产生温室效应，污染环境。在加装空压机热能回收装置后，大部份热能被充分利用，对环境起到保护作用，同时降低能耗，还可以改善空压机的运行工况。介绍了两种实用的空压机热能回收装置，装置已经投入实际生产使用，效益显著。%Discharge temperature of air compressor is often up to 85 ℃~ 102 ℃ when it runs for long time. A large amount of heat energy exists in the discharge air. The heat before is unused, it is referred to as waste heat, taken away by the fan or cooling water and it is discharged to atmosphere, it could come into a“greenhouse effect” and pol ute the environment. After instal ing the air com-pressor heat recovery unit, most of the heat energy is ful y used the energy consumption is reduced and the environment is protec-ted. This paper introduces two practical air compressor heat recovery units. The units are put into use in the process of production and the benefit is remarkable.
