technical field [0001] The invention relates to the field of graphene production equipment, in particular to an energy-saving reaction device for producing graphene using the Hemer method. Background technique [0002] When graphene is prepared by the Hermer method, the dried graphene oxide is dispersed in an aqueous solution to obtain a brownish-yellow suspension. After the suspension is dispersed for a period of time under ultrasonic conditions, the solution is removed and put into a beaker, and the temperature is raised to 80 Celsius, add hydrazine hydrate dropwise to reduce the suspension, filter the reactant, wash the obtained product with methanol and water, and put the obtained fixation in a drying oven to fully dry to obtain graphene.

Problems solved by technology

[0003] From the above-mentioned Hemmer method operation steps, it can be obtained that in the graphene oxide suspension suspended by hydrazine hydrate reduction, it is necessary to maintain a high temperature state, and when the traditional reaction device is heated, because the device is connected to the outside, the outside world where the heat is emitted , the heating device is required to continuously supply heat, which causes the equipment to consume a lot of energy to heat the reaction solution. Not only that, when the graphene oxide suspension is reduced with hydrazine hydrate, as the reaction progresses, a gel that is insoluble in water is gradually formed. The reactant causes hydrazine hydrate to be unable to fully contact with graphene oxide, which affects the reduction quality of graphene oxide, which in turn leads to a reduction in the practicability of the existing Hemer method graphene production reaction device
