▎ 摘　　要

NOVELTY - The device has a reaction device (2) and a support device (5). A mounting hole is opened in the middle position of the support device near the top, and the reaction device is mounted on the support device through the mounting hole. The reaction device comprises a feed portion (1), a reaction portion and a discharge portion (3). The discharge portion includes a discharge pipe, the outer wall of the discharge pipe is provided with a second motor. The outer wall of the discharge pipe is provided with a fixing plate at the position opposite to the second motor. The second roller is connected to the fixing plate through a connecting shaft, and the first roller and the second roller are covered with filter belts. A collection device (4) is provided below the second roller for collecting impurities generated by the filtering of the filter belt, and a sealing sheet (38) is provided inside the discharge pipe at a position above the filter belt. USE - Production device of graphene for air purification. ADVANTAGE - The production device of graphene for air purification has high reaction efficiency, and is environment-friendly. The device has simple structure, which can ensure the sealing and reaction efficiency of the whole reaction device, and avoids the pollution to the environment.
