▎ 摘　　要

NOVELTY - Preparation system for producing graphene comprises a feeding module used for graphene preparation the material into the reaction kettle. The temperature control module is used for controlling the temperature around the graphene preparation around. The atmosphere module is used for controlling the gas component around the graphene preparation around the reaction kettle post-processing module. The post-processing module is provided with a filtering module, a washing module and a dry module. The filtering module is used for carrying out solid-liquid sieving to the graphene preparation and reacted material to obtain the solid intermediate product. The washing speed of the washing module is related to the distribution state of the solid intermediate product on the filter module. The filter module comprises a first filter module and a second filter module. The washing module synchronously washes the solid intermediate product on the first filter module and the second filter module. USE - The preparation system is useful for producing graphene. ADVANTAGE - The system improves production graphene of the powder and the filtering, washing and dry process are carried out in the same device, avoids the waste and pollution caused by the graphene between different devices, and improves the production efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of the preparation the preparation. Reaction kettle (100) Post-processing module (200)
