design of H_(2)SO_(4) pickling spent liquor treatment
作净水剂和制取聚合硫酸铁和氧化铁红的原料。 废液来源与特性硫酸酸洗废液来源于钢材的酸 洗，主要含有硫酸(HzSO‘)5%~10%，硫酸亚铁 (FeSO;)一7%~23%，水70%~75%。其比热容一般 为3.224kJ/(kg·℃)，密度一般为1.269/em3，温度 一般为60~80℃。硫酸亚铁在硫酸溶液中的溶解度变 化规律是，当温度不变时其榕解度随酸度的增大而降 低;当酸度不变时其溶解度随温度的升高而增大，在 55℃左右时为最大，当大于或小于此温度时，其溶解度 均急剧下降，都将有硫酸亚铁结晶析出。 处理工艺冶金厂常用的处理工艺主要有蒸喷真 空结晶法、蒸发浓缩冷冻结晶法、聚合硫酸铁法、铁屑 法和扩散渗析法等。尚有氧化铁红一氨再生法，因其设 备多、能耗高，采用较少。处理装置的能力通常按每年 酸洗钢材消耗的硫酸量(浓度98%)来表示，一般小 型装置为soot/a左右，大型的为1000~300ot/a。 蒸喷真空结晶法通过蒸汽喷射器和冷凝器使蒸 发器和结晶器保持一定真空度的方法。当温度大于该 真空度下蒸发温度的废液通过时，废液中的水分在绝 热状态下蒸发，从而废液温度降低，浓度提高，并相应Iiusuan SUanxi fei，e Chuli sheji降低T硫酸亚铁的溶解度。同时在蒸发器中加入新酸，硫酸酸洗废液处理设计(design of HZSO;提高溶液酸度，使过饱和部分硫酸亚铁结晶析出，其工piekling spent liquor treatment)从硫酸酸洗艺流程见图i。’这种方法的优点是处理废液量大，可连钢材的废液中回收可利用物质的处理设施的设计。硫续生产七结晶水硫酸亚铁(F eso;·7H20)和再生酸酸酸洗废液经过处理后可回收再生酸和硫酸亚铁或制(含H2sO410%~20%，含FesO;4%一8%)。Feso;取聚合硫酸铁。再生酸回用于钢材酸洗，硫酸亚铁可用7H20纯度大于95%，含H2504小于1%。
