Preparation method of dust removal and denitration integrated ceramic filter cartridge and prepared ceramic filter cartridge

The invention discloses a preparation method of a dust removal and denitration integrated ceramic filter cartridge, and relates to the technical field of ceramic filter cartridges. Comprising the following steps: (1) mixing tetrabutyl titanate with absolute ethyl alcohol to obtain a mixed solution a, and dipping a ceramic fiber tube in the prepared mixed solution a; (2) transferring the ceramic fiber tube impregnated in the step (1) into a drying oven for drying; (3) adding ammonium metavanadate and ammonium metatungstate into deionized water, heating and dissolving to obtain a mixed solution b; (4) dipping the ceramic fiber tube dried in the step (2) in the mixed solution b prepared in the step (3); and (5) sintering the ceramic fiber tube impregnated in the step (4), and cooling along with a furnace after sintering. According to the invention, the denitration catalyst is adsorbed to the inside and the surface of the dedusting fiber tube in the form of powder, and then is fixed by using an inorganic glue cur
