▎ 摘　　要

NOVELTY - The device has a heating device for heating copper to a molten state that is arranged in a cavity (1) . The cavity is connected with a gas inlet device. The gas inlet device leads the hydrocarbon mixed gas into the heating device. One side of the cavity is connected with a collecting device (4). The collecting device is used for collecting graphene generated by the reaction of the mixed gas. The cavity is also connected with a cooling device for cooling the gas mixture generated by the reaction. The water cooling device comprises a water cooling source, a circulating pipe and a water pump. The circulating pipe comprises a water cooling section wound on the upper end of the cavity and the water cooling section is used for cooling a gas mixture entering the collecting device. USE - Device for preparing graphene powder by bubble chemical vapor deposition method. ADVANTAGE - The carbon hydrogen gas is introduced into the heating device through the air inlet device, and the melted copper contact the carbon atom accumulation forms graphene and enters the collecting device along with the air flow and is collected, so that the graphene is continuously produced. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing graphene powder by bubble chemical vapor deposition method.
