NOVELTY - A graphene a simple preparation device, comprising a reaction, a furnace body, a spray gun and spray gun, a. install a b. internal furnace body, and are coaxially set, said lance tube through the furnace body and extends in the reaction room, the spray gun and a side wall of the reaction into a 30 degrees included angle, the spray gun b mounting a spray gun, a spray gun and a spray gun between a set has a regulating mechanism to a position for adjusting the spray gun. The utility model is new type can be very suitable for spray gun at the position in the gun tube adjustment process, thus it increase the graphene product quality.
