摘要
"三石膏"是当前迅速发展的工业生产中产生的3种主要的石膏,分别是酸法钛白生产副产的钛石膏、磷化工副产的磷石膏以及工业炉窑尾气脱硫副产的脱硫石膏。"三石膏"因处置方式的局限性而大部分简单地堆存于渣场,由此带来一系列严重的环境问题。针对当前"三石膏"利用率低的问题,分析了"三石膏"基本特征以及应用现状,并提出了"三石膏"循环利用新工艺。
“Three-gypsum”means three main types of gypsum produced in the rapidly developing industrial production,including titanium gypsum by-produced in the acid-route production of titanium dioxide,phosphor-gypsum by-produced in the phosphorus chemical industry,and desulfurization gypsum by-produced in the industrial furnace kiln tail gas desulfurization plaster.At present,most of“three-gypsum”are simply stored in the slag yard due to the limitation of the disposal method,which will cause a series of serious environmental issues.Aiming at the current low utilization rate of“three-gypsum”,the basic characteristics and application status of“three-gypsum”are analyzed,and a new process to recycle“three-gypsum”is proposed.
