一些流经硫酸暴露空气的管件可能会吸潮腐蚀

有干燥器,硫酸储罐设计你可以看看
Reply #52020-01-10
加氮封或者通气管加干燥器

测下壁厚吧,有氢气爆炸特性是一个,如果腐蚀严重泄露后,事故更严重。

设个呼吸阀效果就会好很多,也可以在储罐内壁涂覆特殊涂层防腐

这个情况,设计一般不予考虑:能产生氢气时,硫酸浓度至少要低于70%,要吸收的大量水份,不是一个正常状态,也不是一个正常的故障状态能达到的。硫酸的蒸汽压很小,大小呼吸吸收的水份也相当少,故一般只要不是液面长时间不动(停用好几天以上的情况),不用考虑相界面的腐蚀,而长时间不用情况应是生产管理要考虑的,采用相应的手段来防止。 但如果是生产管理,是要考虑的,至少动火前要确定,这个酸罐是不是长时间不用了?是否有可能进水了?等等之类,故动火前要进行分析和化验,以防止爆炸。
