摘要:

随着中国工业的不断发展,产生了大量的脱硫石膏,目前脱硫石膏的综合利用量虽在逐年增加,但其利用率却在降低,探寻脱硫石膏的高值化利用途径迫在眉睫,其中脱硫石膏资源化利用途径之一是将其脱水转化成α-半水石膏。利用脱硫石膏来制备高性能、高附加值的α-半水石膏,不仅能减轻石膏堆积对环境的污染,减少天然石膏的开采,还能带来新的经济效益。基于此,系统地综述了国内外脱硫石膏制备α-半水石膏的研究现状及影响因素,总结了其生产工艺路径及应用,并对推进脱硫石膏的减量化、资源化利用提出了展望,旨在提高固废利用率,促进“碳中和、碳减排”。

Abstract:

With the continuous development of China's industry,a large amount of desulphurization gypsum has been produced.At present,although the current comprehensive utilization of desulfurization gypsum is increasing year by year,its utilization rate is decreasing,and it is indispensable to explore the high-value utilization path of desulfurization gypsum.One of the ways to resource utilization of desulfurization gypsum is to dehydrate and convert it into α-hemihydrate gypsum.Using desulfurization gypsum to prepare high-performance and high-value-added α-hemihydrate gypsum can reduce the environmental pollution caused by gypsum accumulation,reduce the mining of natural gypsum and bring new economic benefits.Based on this,the current research status of the methods of preparing α-hemihydrate gypsum from desulphurization gypsum at home and abroad and its influencing factors were systematically reviewed,its production process path and its applications were summarized,and the prospect of promoting the reduction and resource utilization of desulfurization gypsum were put forward,aiming to improve the utilization rate of solid waste and promote“carbon neutrality and carbon emission reduction”.

Key words: desulfurization gypsum, α-hemihydrate gypsum, process path, resource utilization
