硫酸生产中电除雾器的腐蚀及改进

Corrosion and Improvement of Electric Demister in Sulfuric Acid Production

电除雾器的钢梁组合件一直采用铅板作防腐蚀层 ,投资高、工艺难度大。经实践 ,改用PVC塑料作为防护层后 ,腐蚀问题得到了解决。

The lead coating for the corrosion protection of the steel structure in the electric demister required higher investment and difficult process. The replacement of the lead coating with the PVC coating has provided effective corrosion protection and reduced the cost.
