摘　　要：生产己内酰胺最重要的工艺过程就是环己酮肟液相贝克曼重排反应过程,其中连续三级重排反应器是主要设备之一。针对工艺环境对设备的影响,采用故障模式与影响分析(FMEA)方法对反应器进行失效分析,但是传统的FMEA主观性太大,精确度低。根据专家调查表,引入模糊综合评判方法进行建模分析,采用层次分析法(AHP)确定权重向量和风险等级。模糊综合评价对FMEA进行定量转化,使重排反应器的风险评估更加合理。Three-stage consecutive rearrangement reactor is the main device for cyclohexanone oxime＇ s Beck- mann rearrangement reaction. Aiming at the environmental influence on the equipment, the method of failure mode and effect analysis （FMEA） was applied to the reactor failure analysis, but its low accuracy exists. The fuzzy comprehensive evaluation method was introduced to the modeling analysis, including the analytic hierar- chy process （AHP） to determine both weight vector and risk level. The results show that this fuzzy FMEA quantitative analysis method can make the safety assessment of the rearrangement reactor more reasonable.
