Abstract
Embodiments of the invention provide a seawater desalination device, including a steam re-compressor configured to pressurize steam by pressurizing a steam; a first heat exchanger configured to exchange an amount of sensible heat of seawater to be desalinated with an amount of liquid sensible heat after pressurized steam is condensed, and an amount of sensible heat of a concentrated liquid after seawater is concentrated; a second heat exchanger configured to exchange an amount of heat of pressurized steam, an amount of latent heat of vaporization of seawater, and an amount of sensible heat when seawater is evaporated, and configured to concentrate seawater; a seawater supply means; a steam supply means; a first discharge means; a second discharge means; and a water-droplet separation means.
