摘要
石灰石-石膏法脱硫装置中吸收塔的腐蚀在整个装置中是最严重的,而吸收塔是整个装置中最重要的设备,直接决定脱硫效率的高低,从而对吸收塔的防腐衬里材料的选择、设计和施工尤为重要。丁基橡胶作为吸收塔的衬里材料在国外得到了广泛应用,对吸收塔的腐蚀机理、衬里橡胶的性能及应用中的问题进行了探讨,指出我国应在脱硫装置中推广应用橡胶作为防腐材料。
Corrosion occurred in the absorber is the most severe problem in the limestone-gypsum FGD plant. Because the absorber acts critical function to the desulphurization in the system, it affects directly the desulpburization effect. Thus, selection, design and construction process of lining antieorrosion materials are important especially. Butyl （IIR） has been widely used as lining material of the absorber at abroad. In this article, the mechanism of the corrosion occurred in the absorber, properties of lining rubber and existed problems were researched. It was indicated that the rubber should be furthermore applied domestically to the FGD as antieorrosion material.
