▎ 摘　　要

NOVELTY - The system has a graphite reaction gas bottle (1) connected with a pressure reducing valve (2), where an outlet part of the pressure reducing valve is connected with a recycling pressurizing pump (3). The recycling pressurizing pump is connected with an outlet part of a gas storage tank (4) that is connected with a high-pressure pump. A gas input pipeline (5) is connected with the high-pressure pump that is connected with an outlet part of a reaction kettle (6). The reaction kettle is fixed with the pressure reducing valve and an inlet part of a recycling pipe (7). USE - Graphene reaction gas recycling and storing system. ADVANTAGE - The system is simple in structure and inexpensive, and has high recycling efficiency, and reduces gas wastage. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene reaction gas recycling and storing system.
