摘　　要：尿素水解系统可能存在尿素溶液污染除盐水、氨气带水、伴热管道效果差、喷氨管道堵塞等故障,影响设备的环保效率。为了解决上述问题,提出一种基于多元状态估计技术的尿素水解系统预警算法。该算法采用多元状态估计对尿素水解系统进行状态监测,得到状态评估值与真实值的残差用于判别该系统是否异常。经实验验证,该算法能够实现对尿素水解系统的状态监测,实现提前预警。The urea hydrolysis system may have failures such as urea solution pollution demineralized water,ammonia with water,poor effect of heat tracing pipeline,blockage of ammonia spray pipeline,which affects the environmental protection efficiency of the equipment.To solve these problems,the paper propose a urea hydrolysis system early warning algorithm based on multivariate state estimation technology.The algorithm monitors the status of urea hydrolysis system using multivariate state estimation,and obtains the residual of the status evaluation value and the true value to distinguish whether the system is abnormal or not.Experiments show that the algorithm can monitor the status of urea hydrolysis system and realize early warning.
