▎ 摘　　要

NOVELTY - An air purifying device based on biomass protein-graphene nanocomposite material, includes a shell (1) provided with a purifying cavity (2), an air inlet cavity (3) and a multi-stage filter cavity (4) from bottom to top, where each cavity is separated by a porous plate. The bottom of the shell is provided with a base (5), and the top of the shell is provided with a purified gas outlet structure (6). The purified gas outlet structure is connected with the multi-stage filter cavity. The purifying cavity is detachably provided with a graphene aerogel net column (7). Outside of the graphene aerogel net column is circulating water cavity (8). The lower portion of the circulating water cavity is provided with a water inlet (9). The upper portion of the circulating water cavity is provided with a water outlet (10). USE - Air purifying device based on biomass protein-graphene nanocomposite material. ADVANTAGE - The air purifying device utilizes three-dimensional macroporous graphene aerogel placed in the graphene aerogel mesh column to adsorb impurities in air, cooperatively circulates water washing, and circulates and purifies air by adsorption.
