NOVELTY - The utility model claims a method of using graphene for sea water desalination device, comprising a box body, a graphene penetrant film, fixing plate, the through hole, the box body is provided with the graphene positive osmosis membrane, the graphene positive osmosis film side is provided with the fixing plate, the fixing plate is provided with the through hole, the inner side of the box is provided with a liquid level sensor, the liquid level sensor and the graphene being permeable film is provided with a stirring rod, the stirring rod is provided with a rotating shaft. The beneficial effects are as follows: the utility model is provided with graphene penetrant film. The graphene penetrant osmotic pressure difference on two sides of the film membrane separation process water as power to realize transmission, good separation effect, by setting filtering net and active carbon adsorption layer, the sea water can be of primary filter, avoid the normal operation of impurities affecting the device in sea water, by setting the observation window, can know the degree of desalting sea water, convenient to master processing progress.
