NOVELTY - The utility model claims an anti-icing mixer and natural gas engine; the anti-icing mixer comprises a mixer shell, a graphene heating layer and a protective layer; the inner wall of the mixer shell is provided with a graphene heating layer; the graphene heating layer can heat; the protective layer is an insulating layer; the protective layer covers the outer wall of the graphene heating layer. when the anti-icing mixer is used, the graphene heating layer on the inner wall of the mixer shell is heated; the mixed gas in the anti-icing mixer is heated to prevent the inner wall of the mixer from icing. In addition, the protective layer made of insulating material covers the outer wall of the graphene heating layer; on the one hand, it avoids the graphene heating layer leakage, improves the safety of the anti-icing mixer; On the other hand, because the gas in the mixer is easy to form weak acid will be corrosive, and the protective layer is set to prevent the graphene heating layer is corroded.
