Graphene powder producing equipment

Abstract

The invention discloses graphene powder producing equipment. The graphene powder producing equipment comprises a furnace body with an accommodating space and a reaction chamber with an accommodating space, wherein at least one nozzle ring is arranged on the side wall of the reaction chamber; the nozzle ring is connected with the outside through feed pipes; a gas inlet is formed in the upper end ofthe reaction chamber; a discharge port is formed in the lower end of the reaction chamber; an isolation valve is arranged at the gas inlet; a discharge valve is arranged at the discharge port. The graphene powder producing equipment has the beneficial effects as follows: the graphene powder producing equipment can produce more graphene in a shorter time, so that the production efficiency is improved and industrialization can be achieved; in addition, the graphene powder producing equipment is simple and convenient to operate, provides possibility for a later automatic process, reduces the production cost, and has a great practical significance in production.

Description

technical field [0001] The invention relates to a graphene preparation device, more specifically, to a graphene powder manufacturing equipment. Background technique [0002] Graphene is a two-dimensional carbon atom crystal discovered by Andre K. Geim of the University of Manchester in 2004. It is a single-layer or multi-layer extremely thin carbon material. Due to its unique structure and photoelectric properties, graphene has become a research hotspot in the fields of carbon materials, nanotechnology, condensed matter physics and functional materials, attracting many scientific and technological workers. Single-layer graphene has excellent electrical and thermal conductivity and low thermal expansion coefficient, and its theoretical specific surface area is as high as 2630m2 / g. It can be used in effect transistors, electrode materials, composite materials, liquid crystal display materials, sensors, etc. At present, the methods for preparing graphene mainly contain graphit...

Problems solved by technology

The chemical oxidation-reduction method is currently the easiest method to achieve industrialization. At present, it is mainly the reduction of hydrazine hydrate solution. First, graphite oxide is prepared, and then the graphite oxide is made into a solution with a concentration of about 1g / L and placed in the reaction axe. The reduction takes 24 hours or less. Longer (see references: Sasha Stankovich, Dmitriy A Dikin, Richard D Piner, et al. Carbon2007, 45, 1558), this hydrazine hydrate solution reduction method not only needs to use a large reaction axe, which takes up a lot of space, but also requires a long reaction time Too long, can not be prepared continuously, low production efficiency
