摘　　要：利用等熵增压技术,开发一种压力能量回收设备,实现高压气源的多余压力能传递给低压气增压,使高低压气源同时满足输气管网压力而进行外输。运行过程几乎没有机械能与气体内能的转化,接近于等熵过程,几乎最大限度地利用了高压气体的压力能。The isentropic boosting technology is adopted to develop a pressure energy recovery device,which can transfer the excess pressure energy of the high-pressure gas source to the low-pressure gas for pressurization so that the high and low pressure gas sources can simultaneously meet the pressure of the gas pipeline network for exporting.There is almost no conversion of mechanical energy and internal energy of gas in the operation process,which is close to the isentropic process and the use of the pressure energy of high-pressure gas is maximized.
