摘要
脱硫石膏作为一种工业副产品,已越来越广泛地用作水泥外掺料、缓凝剂、建筑及防火板材等工业原料,但脱硫过程中产生的SO2、CO2等废气造成的二次污染危害极大,应加大对其综合利用的深入研究。分析了钙法技术烟气脱硫的形成,简述了脱硫石膏的工业资源化利用价值。
Desuffurization gypsum is a kind of industrial byproduct and is more and more used as cement admixture, retarder, building material, fire prevention board and so on,but the SO2 and CO2 produced in the process of desuffurization brings about great secondary pollution. The deeper research of its comprehensive application should be strengthened. The present paper analyses the formation of calcium technique flue gas desuffurization and the industrial resource utilization value of desulfurization gypsum.
