Fuel filter separator based on nano-graphene material

The invention provides a fuel filter separator based on a nano-graphene material. The fuel filter separator comprises an oil-water separation shell, an impurity-filtering shell, a coarse filter, a magnetic ring, a fine filter mesh, a demulsification component, a water collecting tank and an oil-water separation component, wherein the oil-water separation shell and the impurity-filtering shell areconnected to form a combined shell and communicate with each other; a transfer pump is arranged out of the impurity-filtering shell; the inlet of the transfer pump is connected with the coarse filter,and the outlet of the transfer pump is connected with the impurity-filtering shell through a pipeline; the inlet, located in the impurity-filtering shell, of the pipeline is provided with the magnetic ring; the demulsification component sleeves the fine filter mesh; the magnetic ring is located inside the fine filter mesh; the oil-water separation component is arranged inside the oil-water separation shell; and the water
