Resource utilization method for co-processing stale garbage screen underflow through cement kiln
The invention provides a resource utilization method for cement kiln co-processing stale garbage screen underflow. The method comprises the step of preparing the stale garbage screen underflow into cement clinker through cement kiln co-processing. The cement clinker is prepared from the following raw materials in parts by weight: 0.5 to 10 parts of modified screen underflow, 85 to 95 parts of limestone, 2 to 5 parts of phyllite, 8 to 12 parts of iron tailings, 10 to 15 parts of bauxite and 1 to 4 parts of fly ash. And the undersize product is modified, so that the undersize product is better combined with the limestone, the phyllite, the iron tailings, the bauxite and the fly ash, the adhesive force and the binding force among the materials are improved, and the performance of the cement is remarkably enhanced. Screen underflow screening comprises manual primary screening, first-stage vibration screening, magnetic separation, wet screening, second-stage vibration screening and third-stage vibration screening. In the wet screening process, the modified adsorption resin is used for adsorbing chlorine elements and heavy metal substances in the screen underflow, so that the screen underflow reaches the kiln entering standard, and meanwhile, the peculiar smell of the screen underflow can be removed.
本发明提供一种水泥窑协同处置陈腐垃圾筛下物的资源化利用方法，该方法包括利用水泥窑协同处置将陈腐垃圾筛下物制成水泥熟料。所述水泥熟料包括以下重量份原料：0.5‑10份改性筛下物、85‑95份石灰石、2‑5份千枚岩、8‑12份铁尾矿、10‑15份铝矾土、1‑4份粉煤灰。对筛下物进行改性，使其更好的与石灰石、千枚岩、铁尾矿、铝矾土、粉煤灰结合，提高材料之间的粘附力和结合力，显著增强水泥的性能。筛下物筛选包括：人工初选、一级振动筛选、磁选、湿法筛选、二级振动筛选、三级振动筛选。湿法筛选使用改性吸附树脂对筛下物氯元素及重金属物质进行吸附，使其达到入窑标准，同时可以去除筛下物的异味。
