Title: SEAWATER DESALINATION SYSTEM AND ENERGY RECOVERY DEVICE
Abstract:
The present invention relates to a seawater desalination system for desalination of seawater by removing salt from the seawater and an energy recovery device suitably used in the seawater desalination system. The energy recovery device is provided with: a circular cylindrically shaped chamber (CH) with the longitudinal direction thereof being aligned with the vertical direction; a first perforated plate (24) and a second perforated plate (25) disposed on a concentrated seawater port (P1) side inside the chamber (CH); and a first perforated plate (24) and the second perforated plate (25) disposed on a seawater port (P2) side inside the chamber (CH). The first perforated plates (24) are perforated circular plates and holes are formed in an outer peripheral region outside of a virtual circle with a prescribed diameter concentric with the perforated plate. The second perforated plates (25) are perforated circular plates with holes formed in the entire surface, and the center part of the perforated circular plates is formed in a rotating body shape convexly shaped toward the first perforated plate side.
