含油污泥热处理过程中的腐蚀与控制技术

Corrosion and control technology of oily sludge during thermal treatment

简述了含油污泥的来源及危害。介绍了热解、焦化、焚烧和阴燃等含油污泥热处理技术及其特征,并重点介绍了含油污泥焚烧处理装备的种类和特点。针对焚烧及阴燃过程会产生大量酸性气体,进而加剧设备腐蚀的问题,总结了含油污泥热处理设备腐蚀行为的影响与控制技术,以期更好地为含油污泥热处理过程中腐蚀控制的方法及发展提供参考。

The source and harm of oily sludge are briefly described.The thermal treatment technologies and characteristics of oily sludge,such as pyrolysis,coking,combustion and smoldering combustion are introduced.The types and characteristics of oily sludge combustion equipment are emphatically introduced.In view of the problem that a large amount of acid gas will be produced in the combustion and smoldering combustion process,which will further aggravate the corrosion of equipment,this paper summarizes the influence and control technology of the corrosion behavior of the oily sludge thermal treatment equipment,in order to provide a better reference for the corrosion control methods and development in the oily sludge thermal treatment process.
