▎ 摘　　要

NOVELTY - The filtering film has a coarse filtering layer (1), an oxidation graphene filter film layer (2), an inner film reinforcing layer (3), a hollow fiber filter film layer (4) and an outer film reinforcing layer (5). An inner surface of the coarse filtering layer is arranged with the oxidation graphene filter film layer, the inner film reinforcing layer, the hollow fiber filtering film layer and the outer film reinforcing layer. The film reinforcement layer is uniformly orderliness of porous net-shaped structure. USE - Filtering film for industrial boiler smoke. ADVANTAGE - The filtration efficiency of ultrafine dust particles is increased, and the treatment effect of denitration is improved. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the filtering film for industrial boiler smoke.
