WORK-EXCHANGE TYPE ENERGY RECOVERY DEVICE

A work-exchange type energy recovery device comprises a non-rotating assembly and a rotating assembly, wherein the rotating assembly comprises a driving shaft, an upper driving disk, a driving pipe, a lower driving disk and a driven shaft which are fixed relative to each other and securely connected. And the energy recovery device achieves the stable pressure-based energy exchange by means of motor drive, flow distribution on the end surface and self-tight sealing. The energy recovery device employs the self-tight sealing structure and the water-lubrication static-pressure supporting technology on the distribution surface, thus avoiding the leakage from the high-pressure flow distribution surface in substance. The energy recovery device has the advantages of high efficiency, safety, stability, long service life and low noise. La présente invention a trait à un dispositif de récupération d'énergie de type à échange de travail qui comprend un ensemble non rotatif et un ensemble rotatif, lequel ensemble rotatif
