Acid slurry flat plate denitration catalyst, preparation method thereof and application of catalyst in cement kiln

The invention discloses an acidic slurry flat plate denitration catalyst, a preparation method thereof and application of the catalyst in a cement kiln, and belongs to the technical field of denitration catalysts. The catalyst is composed of a supporting body and catalyst paste coated on the supporting body, and the catalyst paste comprises the following components in parts by weight: 50-70 parts of carrier titanium dioxide, 1-3 parts of ammonium metatungstate, 5-10 parts of silicon dioxide, 1-10 parts of a binder, 0-1 part of zirconium acetate, 0.4-1.2 parts of ammonium metavanadate, 1-3 parts of ammonium heptamolybdate and 3-5 parts of glass fibers; the binder is composed of polyethylene wax, lactic acid, polyanionic cellulose and polyoxyethylene; according to the acidic slurry flat plate denitration catalyst provided by the invention, the acidic slurry is used for replacing currently common alkaline slurry, so that the acidic slurry flat plate denitration catalyst has richer acidic sites, and the denitrati
