硫酸生产中电除雾器的腐蚀及防腐方法的改进

Corrosion And Improvement on Anticorrosion of Electric Mist Collector in Sulphuric Acid Production

电除雾器的钢梁组合件一直采用铅板作防腐层，投资高、工艺难度，而且不可能从根本上解决腐蚀问题。经实践，改用ＰＶＣ塑料作为防腐层后，腐蚀问题就解决了。

Anticorrosive lead lining is usually employed for the combined steel beam of electric mist collector. The method is expensive investment,difficult of technology and impossiblc to solve the corrosive problem once for all. The anticorrosive problem with the electric mist collector is solved when PVC plastic lining is used.
