Industrial solid waste full-cycle comprehensive utilization process method
The invention provides an industrial solid waste full-cycle comprehensive utilization process method. The process method comprises the following steps: purifying industrial gypsum raw slag by using a cleaning agent to obtain gypsum slag and a purified liquid; calcining the gypsum slag to obtain gypsum powder and secondary steam, and condensing the secondary steam to form steam condensate; carrying out synthesis treatment on the purified liquid and a metal oxide raw material to obtain a solid, separating out the solid, and separating to obtain synthetic water; the cleaning agent is one or more of the synthetic water, the purified liquid and the steam condensate. By adopting the technical scheme of the invention, most of harmful impurities and water in the industrial gypsum raw slag are removed, the cleanliness and dryness of the gypsum are greatly improved, various byproducts generated in the industrial gypsum raw slag are reasonably and effectively recycled, the effective utilization rate of resources is improved, resource waste is reduced, and secondary pollution of the byproducts to the environment is avoided.
本发明提供一种工业固废全循环综合利用工艺方法,包括以下步骤:采用清洗剂对工业石膏原渣进行净化处理后制得石膏渣和净化液;再对所述石膏渣进行煅烧处理后制得石膏粉和二次蒸汽,并使二次蒸汽冷凝形成汽凝水;然后使净化液与金属氧化物原料经过合成处理后制得固体物析出并分离获得合成水;所述清洗剂是所述合成水、净化液、汽凝水中的一种或多种。采用本发明的技术方案,脱除了工业石膏原渣绝大部分有害杂质和水,大幅度提高了石膏洁净度和干燥度,对其中产生的各种副产物进行了合理有效的循环利用,提高了资源有效利用率,减少了资源浪费,避免副产物对环境造成二次污染。
