▎ 摘　　要

NOVELTY - The hydrogen-water graphene battery hydrogen recycling device comprises a base (1), where one end of the top of the base is fixedly provided with a water filtering cabin (2). The bottom end of one side of the water filtering cabin is fixedly provided with an air inlet pipe (3). The bottom of the water filtering cabin is provided with an engine cabin (4). The engine cabin is installed with a motor (5) through the mounting seat. The bottom of the water filtering cabin is movably provided with a screw rod. USE - Hydrogen recycling device is useful for the low-pressure operation of hydrogen-water graphene battery. ADVANTAGE - The device is suitable for low-pressure operation, can be mixed gas into the hydrogen extracting tank, the water in the mixed gas filtering, convenient for the subsequent work of the hydrogen extracting tank, improves the recycling effect of the hydrogen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a hydrogen recycling device. Base (1) Water filtering cabin (2) Air inlet pipe (3) Engine cabin (4) Motor (5)
