吸气参数对空压站能效影响的研究分析

Research and Analysis of Influence of Suction Parameters on Performance of Air Compressor Station

为了研究吸气参数对空压站运行能效的影响,本文通过优化改进空压站测量系统,采集不同温、湿度环境下空压站运行时的参数,分析吸气参数对空压站能效的影响。结果表明,当进气温度不变时,进气相对湿度每减少10%,生产1 m^3的压缩空气机组耗电量将减少0.0058 kWh,能耗降低4%。当进气相对湿度保持不变时,进气温度从30℃上升到35℃,空压站的能耗增加了20%,温度每升高1℃,生产1 m^3的压缩空气机组耗电量将增加0.00516 kWh。根据相同湿度不同进气温度下空压机组比能量的变化,提出机组进气温度应保持在15~30℃以保证空压机组高效运行。为通过改变吸气参数对空压站进行节能提供了理论及实验依据。

In order to study the influence of suction parameters on the energy efficiency of air compressor station a air compressor station measurement system was built to acquire the parameters of air compressor station in different temperature and humidity which used to analyze the influence of suction parameters on the performance of air compressor station.Results show that when the relative humidity of the air compressor decrease by 10%,the power consumption of the compressed air producing 1 m^3 will decrease 0.0058 kWh and the energy consumption will decrease by 4%with constant suction temperature.The energy consumption of the air compressor station increases by 20%when the suction temperature rises from 30℃to 35℃,the power consumption of the compressed air producing 1 m^3 will increase 0.00516 kWh when the suction temperature of the air compressor station increases 1℃.The suction temperature of the compressor station should keep at 15~30℃to ensure the high performance of the air compressor station according to the change of the specific energy of the air compressor station under different suction temper-ature.It provides theoretical and experimental support for energy saving of air compressor station by changing the suction parameters.
