Preparation method of fly ash-based denitration cement
The invention relates to the field of air pollution control and the technical field of building materials, and discloses a preparation method of fly ash-based denitration cement. The preparation method comprises the following specific steps: (1) grinding fly ash, and uniformly mixing the ground fly ash with cement clinker, gypsum, a pore-forming agent, a binder and a strength additive to prepare fly ash-based cement; (2) preparing an active component solution, and uniformly mixing the active component solution with the fly ash-based cement; (3) preparing a hollow cylindrical structure by utilizing a 3D printing technology, and then performing steam curing; and (4) thoroughly drying the cement blocks, and then transferring the cement blocks into a muffle furnace for roasting treatment. The preparation method comprises the following steps: preparing high-strength cement by adding an auxiliary agent, then introducing a denitration active component by taking cement as a carrier to prepare denitration cement, carrying out steam curing on a cement blank, and finally roasting to form a porous structure. The fly ash-based denitration cement is suitable for denitration in a low-dust environment and has relatively high denitration efficiency.
本发明涉及大气污染治理领域和建筑材料技术领域，公开了一种粉煤灰基脱硝水泥的制备方法。该制备方法具体步骤如下：(1)将粉煤灰研磨后与水泥熟料、石膏、造孔剂、粘结剂和强度助剂混合均匀制备粉煤灰基水泥；(2)配制活性组分溶液，与粉煤灰基水泥混合均匀；(3)利用3D打印技术制备成空心圆柱状结构，而后进行蒸汽养护；(4)彻底干燥水泥块，然后转移至马弗炉中进行焙烧处理。通过添加助剂制备出高强度水泥，而后以水泥为载体引入脱硝活性组分制备出脱硝水泥，对水泥胚体进行蒸汽养护，最后经过焙烧形成多孔结构。该粉煤灰基脱硝水泥适用于低尘环境脱硝，具有较高的脱硝效率。
