我厂Ⅳ型催化裂化装置于1967年建成投产,1977年该装置停工大修后通过技术改造加大了处理量(由120万吨/年提高到150万吨/年),1981年3月20日又向再生器加注一氧化碳助燃剂,停工大检修时发现筒式反应器旋风分离器翼阀被严重磨损,再生器内构件变形和高温化较为严重。现在就设备损坏状况、原因及相应防护措施谈谈看法。一、设备磨损和氧化、变形状况1.筒式反应器的旋风分离器翼阀磨损情况及处理办法见表1。 The Ⅳ type catalytic cracking unit of our plant was put into operation in 1967. After the equipment was shut down and overhaul in 1977, the plant increased its processing capacity (from 1.2 million tons / year to 1.5 million tons / year), and on March 20, 1981 Again to the regenerator carbon monoxide combustion improver, stop overhaul found that the cartridge reactor cyclone wing valve is severely worn, the deformation of the regenerator components and high temperature is more serious. Now on the equipment damage, the reasons and the corresponding protective measures to talk about. First, equipment wear and oxidation, deformation 1.
