The present invention relates to a kind of ceramic catalytic filter cores for gas cleaning and flue gas integration desulfurization denitration dust removal method, the ceramic catalytic filter core to be prepared by following methods：Take the microporous aluminum oxide ceramic screen pipe that aperture is 40 80 μm as matrix；Matrix is immersed in mixed sols made of zinc acetate, the Zinc modified modified matrix of oxidation is roasted to obtain after negative pressure impregnation；Using equi-volume impregnating, modified matrix is impregnated with the mixing oxalic acid solution containing ammonium metavanadate and ammonium metatungstate, makes V 2 O 5 And WO 3 Total load quality in matrix duct reaches 4.0% 6.0%, obtains active matrix；Active matrix is immersed into Al 2 O 3 ‑SiO 2 ‑TiO 2 It in complex sol, dries and calcines after taking-up, the dense film that formation thickness is 0.2 0.6mm, aperture is 1 10 μm in active matrix outer surface to obtain the final product.The denitrating catalyst load of the ceramic catalytic filter core is secured, and denitration efficiency is high, and service life is long, is suitble to promote the use of. |
