NOVELTY - A one sea water desalination device, comprise water tank, pipeline and water collector, a water groove comprise fresh water and salt water groove between fresh water and salt water groove cavity is set with semi-penetrate graphene film; a pipeline one end with the salt water cavity connected, and the other end with the seawater collector connected. The sea water desalting device is mainly a seawater self-dependence of wave energy, and a new semi-penetrate graphene film combine with graphene semi-penetrate film osmotic pressure of a working characteristic of sea water desalination, green and environment-friendly, and electric power supply does not need independent of external, save energy and reduce cost.
