Rotary Type Energy Recovery Device

摘要

The present invention relates to an energy recovery device with a rotary volumetric pressure exchange type, and, more specifically to an energy recovery device with a rotary volumetric pressure exchange type which collects pressure energy of seawater (water hydraulic power) which has been filtered in a reverse osmosis desalination apparatus and condensed without disposing into the sea, and drives a hydraulic motor configured with a hydraulic pump as one body so as to reduce electricity consumption as a separate hydraulic motor is not used, thereby reducing energy waste or increasing efficiency.
