NOVELTY - The utility model claims an oil-water separating device of the graphene film, comprising a cylinder, a rotary tray, a rotary power mechanism and a pre-heating device, the cylinder comprises an inner cylinder and an outer cylinder, an inner cylinder lower end base sealed on the rotary tray; rotary tray and a rotary power mechanism transmission connection; the inner cylinder comprises a stainless steel mesh are orderly arranged from inside to outside, the lipophilic and hydrophobic graphene film and the stainless steel support pipe; outer cylinder sleeved on the inner cylinder, to form a third containing cavity for containing oil, pre-heating device is connected with the third holding cavity through the first pipeline; the third containing cavity is connected back with the preheating device through the second pipeline. Compared with the existing technology, the utility model drives the rotating tray and the inner cylinder to rotate by the motor, the crude by lipophilic and hydrophobic graphene membrane primary filter, the primary oil filter and then pre-heating the crude oil, oil-water mixture heated uniformly and good oil-water separation effect, directly entering the next petroleum distillation process after oil pre-heating treatment to realize the afterheat recycling and reusing.
