空分设备中主换热器的温差和流动阻力是影响空压机能耗的两个重要因素,通过板翅式换热器不同温差、流动阻力和主换热器设备投资、空压机电耗之间关系的详细数据对比,分析了换热器温差、正/返流阻力对空压机能耗的影响关系,并提出了合理控制换热器温差、合理分配换热器阻力的重要性。
Air separation plant in the main heat exchanger temperature and flow resistance is the impact of air compressor energy consumption of two important factors, through the plate-fin heat exchanger with different temperature, flow resistance and the main heat exchanger equipment investment, air compressor electricity The relationship between the heat and the temperature, the influence of the temperature difference of the heat exchanger and the positive / negative flow resistance on the energy consumption of the air compressor is analyzed, and the importance of reasonably controlling the temperature difference of the heat exchanger and rationally distributing the resistance of the heat exchanger is proposed .
