介绍了在设计、施工和催化裂化装置操作等方面延长重油催化裂化设备衬里寿命的一些经验和措施 ,如不同部位衬里结构、衬里材料和衬里构件材质的选择 ,构件的焊接方式 ,衬里挡板的设计 ,保温钉结构及型式的选择 ,衬里的施工方法以及催化裂化装置的平稳操作等。认为只要采取合理措施 ,就可以使衬里“三年不小修 ,十年不大修”。 Some experiences and measures to extend the longevity of heavy oil catalytic cracking equipment in aspects of design, construction and operation of catalytic cracking unit are introduced, such as lining structure, lining material and lining material selection in different parts, welding method of components, lining baffle Design, insulation nail structure and type of choice, the lining of the construction methods and catalytic cracking unit, such as the smooth operation. That as long as reasonable measures to take, you can make the lining “three years without major repair, ten years without major repair.”
