▎ 摘　　要

NOVELTY - The module has a fiber membrane (2) that is fixedly connected to the inside of the casing (1). An exchange channel (3) is fixedly connected to the inside of the casing and is located on the surface of the fiber membrane. The internal active connection of the exchange channel is connected to the limited flow mechanism (4). A spring rod is movably connected to the inside of the adjusting plate. The end of the spring rod which is away from the adjusting plate is movably connected with the blocking plate. A flexible tube (8) is movably connected to the connection between the blocking plate and the spring rod. A circulation mechanism (9) is movably connected to both sides of the casing. The circulation mechanism is arranged with a rotating shaft which is sleeved with fan blades. An airbag rod is movably connected to the surface of the rotating shaft and the both sides of the fan blade. A guide block is hinged on the surface of the airbag rod. USE - Graphene nanofiber membrane module based on total heat exchange and purification device. ADVANTAGE - When the regulating plate is contacted with the blocking plate, the airflow is directly entered into the inside of the exchange channel, the blocking plate is kept away from the regulating plate. The flexible tube is opened and the airflow will re-enter the interior of the casing. Thus, the normal exchange of gas is ensured. The temperature difference between the fresh air entering the room and the airflow stored in the room is not increased, so the effect that the temperature of the introduced fresh air is close to room temperature and the energy consumption is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a front cross-sectional view of the casing structure of the graphene nanofiber membrane module.
