NOVELTY - The utility model claims a graphene growth system, comprising a catalyst precursor preparation subsystem, a catalyst preparation subsystem, a catalyst modification subsystem, a graphene growth subsystem, a material collecting subsystem, a storage subsystem and a gas source subsystem, wherein the catalyst precursor preparation subsystem, a catalyst preparation subsystem, a catalyst modification subsystem, a graphene growth subsystem and a material collecting subsystem are connected in turn; the storage subsystem is respectively connected with the catalyst modification subsystem and the graphene growth subsystem; the gas source subsystem is respectively connected with the catalyst preparation subsystem and the graphene growth subsystem. The utility model realizes the mass production of high-quality graphene powder by chemical vapour deposition method, and can realize controllable growth of graphene. The system is safe and reliable, at the same time, it can effectively solve the tail gas discharge problem generated in the chemical deposition process, avoids the residual gas after reaction directly discharged to the atmosphere caused by pollution.
