生产方法及用途

生产方法

(1)土法 将硫铁矿和煤块加入炼硫炉中经高温焙烧,使硫磺升华,经冷却得粗硫磺,再经熔化、沉淀、铸模成型,制得硫磺块成品。硫磺渣浸泡加热得到土硫酸铵和粗硫磺。尾气经回收塔处理后放空。其主要反应如下。
(2)沸腾焙烧法 硫铁矿用沸腾焙烧产生的二氧化硫气体,经除尘后与鼓风进行混合,在还原炉中加入无烟煤或通入半水煤气进行还原,再经转化器、冷凝器、泡罩塔后放空。液态硫磺由冷凝器、泡罩塔放出经过滤即得硫磺成品。其主要反应式如下。
(3)半磁化焙烧还原法 将硫铁矿尾砂经磁化炉产生气体,经除尘后送入还原炉,炉中加入无烟煤进行还原。再经转化,通过废热锅炉、换热器去一次冷却器,再经换热器、二次转化、二次冷却去泡罩塔。由一次冷却和泡罩塔流出的硫磺送去成品槽,制得硫磺成品。 ...
