Industrial production method for preparing sulphoaluminate cement clinker and co-producing sulfuric acid from all solid wastes
The invention belongs to the fields of comprehensive utilization of solid waste resources, building materials and chemical production, and particularly relates to an industrial production method for preparing sulphoaluminate cement clinker and co-producing sulfuric acid from all solid wastes. The industrial production method comprises the following steps: 1, preparing the following components in percentage by mass (%): 5-75% of phosphogypsum, 0-60% of desulfurized gypsum, 0-45% of fluorgypsum, 0-45% of carbide slag, 3-20% of fly ash, 0-10% of red mud and 3-30% of aluminum ash; 2, feeding the mixture obtained in the step 1 into a particle size sorting system; 3, milling the coarse material by a grinding system until the fineness +80[mu]m screen residue is less than or equal to 10%, and feeding the material into a homogenizing system; 4, finely grinding the sorted fine materials and coarse materials by a grinding system to form ground materials, and homogenizing the ground materials by ahomogenizing system; and 5, calcining the raw material in a multi-stage preheater kiln calcining system.
本发明属于固废资源综合利用、建材与化工生产领域,尤其涉及全固废制备硫铝酸盐水泥熟料联产硫酸的工业生产方法,所述全固废制备硫铝酸盐水泥熟料联产硫酸的工业生产方法包括如下步骤:步骤一:将以质量百分比(%)计,5‑75%的磷石膏、0‑60%的脱硫石膏、0‑45%的氟石膏、0‑45%的电石渣、3‑20%的粉煤灰、0‑10%的赤泥和3‑30%的铝灰;步骤二:将步骤一的混合料送入粒度分选系统;步骤三:粗料经粉磨系统磨细至细度+80μm筛余≤10%,再入均化系统;步骤四:分选所得细料及粗料经粉磨系统磨细后形成的粉磨后料经均化系统均化处理;步骤五:所述生料在多级预热器窑煅烧系统内完成煅烧。
