钢铁企业酸再生系统
The system of acid regeneration in iron and steel industry

　　钢铁企业轧钢酸洗机组中产生的大量废酸液，经浓缩循环后进入焙烧炉热分解。焙烧炉内产生的固体氧化铁粉送至氧化铁粉仓内；产生的气体冷却后进入到吸收塔形成再生酸。
　　The acid cleaning units - used in iron and steel industry - produce a mass of spent acid. After being concentrated and circulated, the spent acid are decomposed in the Roaster. The precipitate of iron oxide from Roaster is sent to the Oxide bin. The gas from the Roaster are cooled, and then put into absorption tower to form regenerative acid.
