▎ 摘　　要

NOVELTY - The device has an oil-water separating module provided with a shell (5) that is connected with a liquid inlet pipe (2) for flowing oil-water mixed liquid. A water conveying pipe (12) conveys separated water phase. A lower part of the liquid inlet pipe is connected with a water conveying pipe. An oil pipe (9) conveys the separated oil phase to the shell. The oil water separation module provides power to a power system that is provided with a motor (6). An electric pump is connected to a last stage oil water separation module, the water conveying pipe and the oil pipe. USE - Graphene composite foam based oil-water separating device. ADVANTAGE - The device avoids damages to a three-phase separator so as to reduce economic loss caused by maintenance stopping phenomenon. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a graphene composite foam based oil-water separating device.
