Dust-removal denitration integrated ceramic filtering material and preparation method thereof
The invention belongs to the technical field of a flue gas catalytic denitration dust-removal technology, in particular to a dust-removal denitration integrated ceramic filtering material and a preparation method thereof. The dust-removal denitration integrated ceramic filtering material has an asymmetrical filtering membrane structure and internally loaded with TiO2-ZrO2-CeO2, wherein the loading amount of TiO2-ZrO2-CeO2 is 8-22%. With the adoption of the material, denitration and dust removal can be completed through one step, the process integration is realized, the problems of big waste of flue gas waste heat and low denitration efficiency in the process that dust removal is carried out firstly and then denitration is carried out are solved, and the problems of catalytic function attenuation and failure in the process that denitration is carried out firstly and then dust removal is carried out, short service life and low operation efficiency of the whole purification system and high cost are also solved; meanwhile, the equipment cost and the operating cost are reduced greatly.
