Denitration ceramic fiber filter tube and preparation method thereof
The invention discloses a denitration ceramic fiber filter tube and a preparation method thereof, and belongs to the technical field of flue gas treatment, and the preparation method comprises the following steps: adding wheat starch and a dispersing agent into deionized water, uniformly stirring to obtain a mixed solution a, adding MgO-loaded porous S < i > C fibers, kyanite powder, clay and molybdenum oxide into a kneading machine, adding the mixed solution a into the kneading machine, and uniformly stirring to obtain the denitration ceramic fiber filter tube. Mixing and aging to obtain pug, extruding the pug to obtain a support body green body, drying the support body green body, and calcining to obtain a support body; the preparation method comprises the following steps: preparing modified nano T < i > O < 2 >, preparing dipping slurry from ammonium metavanadate, deionized water, monoethanolamine, ammonium metatungstate and modified nano T < i > O < 2 >, dipping, drying, calcining, and introducing an active component on the surface of a support body to obtain the denitration ceramic fiber filter tube. And meanwhile, the catalyst has relatively high catalytic efficiency and relatively low powder removal rate.
本发明公开了一种脱硝陶瓷纤维滤管及其制备方法，属于烟气治理技术领域，包括以下步骤：将小麦淀粉和分散剂加入去离子水中搅拌均匀得到混合液a，将载MgO多孔S i C纤维、蓝晶石粉、黏土和氧化钼加入捏合机中，向捏合机中加入混合液a，混合后陈腐，得到泥料，将泥料挤出，得到支撑体生坯，将支撑体生坯先烘干后煅烧，得到支撑体；之后以偏钒酸铵、去离子水、单乙醇胺、偏钨酸铵和改性纳米T i O2组成浸渍浆料，通过浸渍、干燥、煅烧，在支撑体表面引入活性组分，得到脱硝陶瓷纤维滤管，本发明所获得的脱硝陶瓷纤维滤管具有更好的力学性能，同时具有较高的催化效率以及更低的脱粉率。
