▎ 摘　　要

NOVELTY - Reverse osmosis sea water desalting device based on graphene oxide separation membrane comprises an outer tube (1), an inner tube (2) and an end cover (3) located at two ends of the outer tube. The outer part of the inner pipe is polygonal column. The inner pipe is provided with multiple permeable small holes connected with the inner part. The periphery of the inner pipe is provided with a graphene oxide separating film. One end cover is provided with a water inlet. The water inlet is set corresponding to the space between the inner pipe and the outer pipe. The other end cover is provided with a purified water outlet and a waste water outlet. The purified water outlet is set corresponding to the inner pipe. The waste water outlet is set corresponding to the space between the inner pipe and the outer pipe. USE - Used as reverse osmosis sea water desalting device based on graphene oxide separation film. ADVANTAGE - The device avoids the film bending caused by mechanical strength and film structure damage, ensures the bearing capacity and service life of the reverse osmosis membrane and increases the film area of the permeable in unit volume, thus ensuring the high yield of the device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for desalting method of reverse osmosis sea water desalting device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the structure of the reverse osmosis sea water desalting device. Outer tube (1) Inner tube (2) End cover (3)
