钢板酸洗即用盐酸将热轧钢板上的氧化铁皮清除后得到漂亮光滑的表面,使钢板表面缺陷一目了然,便于焊接、涂油及上漆。酸洗过程中,酸液被不断消耗。随着时间的推移,溶液会被不可溶的金属化合物和溶解性金属盐污染。当这些废渣的浓度达到一定值时,溶液便成为废液。目前,对废液的处理大多采用加石灰中和的办法。石灰中和一方面造成环境的二次污染,中和后产生大量的污泥造成环境的再次污染;另一方废酸得不到合理的利用造成资源的浪费。
西安环科公司针对这样的钢板酸洗企业,专门研制了废酸回收设备处理设备,专门帮助企业企业来解决这些困惑。废酸回收设备的特点是:
1、常温再生,能量耗费低;
2、处理量大、性价比高,可根据水质、水量要求进行选型,可调型高,避免资金浪费;
3、设备使用寿命长、维修率低;
4、设备适用范围广,操作简便;
5、酸与金属盐分离,有利于金属盐的回收。废酸液经钝化回收设备处理后,能够实现废水零排放。
