摘　　要：介绍了正位移式压力能回收技术的工作原理和设备结构,并对现有的几种正位移式压力能回收技术进行了对比介绍。相比于传统的采用液力透平的离心式压力能回收技术,正位移式压力能回收技术的能量回收效率要高很多,可以达到90%以上。从石化生产的特点考虑,阀控式正位移压力能回收技术相比于旋转式正位移压力能回收技术更适合应用在石化生产领域中。目前,正位移式压力能回收技术在石化生产领域还没有得到应用,在将正位移式压力能回收技术应用在石化生产领域前,还须要解决物料掺混、系统操作稳定性、设备热变形以及液体降压过程中释放的气体引起的管道和设备振动等问题。The working principle and equipment structure of positive displacement pressure energy recovery technology were introduced. Several existing positive displacement pressure energy recovery technologies were compared and introduced. Considering the characteristics of petrochemical production, valve-controlled positive displacement pressure recovery technology is more suitable to be applied in petrochemical production field than rotary positive displacement pressure recovery technology. At present, the positive displacement pressure recovery technology has not been applied in the petrochemical production field. Before the application of the positive displacement pressure recovery technology in the petrochemical production field, it is still necessary to solve the problems such as the mixing of materials, system operation stability, thermal deformation of equipment and vibration of pipelines and equipment caused by gas release.
