小氮肥企业碳化塔的防腐研究

Research of anti-corrosion on carbonic pagoda in small nitrogenous fertilizer factories

阐述了目前小氮肥企业中碳铵碳化塔的防腐现状 ,并总结了各种防腐措施中存在的问题 .分析了碳化塔设备介质的强腐蚀机理 ,提出其内壁的腐蚀仍是该设备最危险的缺陷之一 ,并针对碳化塔设备的特殊性 ,提出了在其定期检验中应重点注意的几个问题 .就碳化塔设备内壁在防腐中存在的主要问题和其它涉及碳化塔安全运行的几个方面 ,在设备使用管理方面提出了具体的解决办法和应采取的措施 .

This paper analyzes the strong corrosion mechanism of carbonic pagoda's media and points out the corrosion of its internal wall is one of the most harmful defects.Aiming at the carbonic pagoda's particularity, it puts forward some important problems that must be paid much attention during regular test.Finally, aiming at these problems that appear during management of carbonic pagoda's equipment, it provides some specific measures that should be put into practice.
