NOVELTY - The utility model claims sea water desalting field, claims a porous graphene sea water desalting device. the porous graphene sea water desalting device comprises a seawater pre-treatment unit and porous graphene desalination unit, the seawater pre-processing unit for pre-processing the seawater after conveying the porous graphene desalting unit; the porous graphene desalination unit comprising a shell, the upper end of the shell is provided with a water inlet, the lower end is provided with a water outlet, the shell is provided with sieve body layer multilayer graphene, the graphene sieve body of pore size 1 of the porous graphene. The utility model compared with the conventional reverse osmosis technology, there is no need to pressure of the sea water, the cost is low, it saves resource, the structure is more simple, and the filtering efficiency is higher, only the sea water after primary treatment, through the porous graphene desalting desalting treatment to obtain fresh water.
