▎ 摘　　要

NOVELTY - High-pressure graphene material preparing device comprises lever temperature pressure container (1) where the container is cylindrical structure divided into upper and lower two parts. The upper part is a solid pressure pipe and the lower part is a container base. The inner cavity (3) is capable of containing the gas. The solid pressure pipe outer wall is closely attached container inside the base cavity and can move upper lower for rapidly realizing the gas produced by the compression condition of high temperature and high pressure. USE - Used as high-pressure graphene material preparing device. ADVANTAGE - The device is simple, economical, saves energy and reduces the chemical pollution. DETAILED DESCRIPTION - High-pressure graphene material preparing device comprises lever temperature pressure container (1) where the container is cylindrical structure divided into upper and lower two parts. The upper part is a solid pressure pipe and the lower part is a container base. The inner cavity (3) is capable of containing the gas. The solid pressure pipe outer wall is closely attached container inside the base cavity and can move upper lower for rapidly realizing the gas produced by the compression condition of high temperature and high pressure. The container base upper end side wall is provided with an oxygen inlet (6), acetylene or ethylene gas inlet (7).The container base lower end side wall is provided with a graphite extraction outlet (8) and a residual gas outlet. An INDEPENDENT CLAIM is also included for preparing graphene material comprising (i) taking the lever temperature container connected through the oxygen inlet, acetylene or ethylene gas inlet into oxygen and acetylene or ethylene gas, (ii) adding solid pressure pipe quickly falling container inside the base cavity in high temperature and high pressure state, the condition, oxygen and acetylene or ethylene gas of high pressure is generated by chemical reaction, exploding, holding for 10-30 minutes in the container, (iii) reacting gas inside the container through pressure relief cooling treatment, extracting residual gas residual gas outlet is opened, the bottom surface of the container base forming step in the second black product after explosion, scraping -off and extracting the black product through graphene extraction outlet to obtain the graphene material, (iv) cleaning container, sealing the outlet and primary gas, ensuring no other gas from entering and circulating. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of high-pressure graphene material preparing device.
