摘　　要：为保障袋式除尘系统运行安全,预防粉尘燃爆事故发生,提出一种基于偏离度-模糊综合评价(FCE)的袋式除尘系统实时定量风险评价模型。首先,基于工业物联网传感器采集的除尘器进出风口压差、除尘箱温度和锁气卸灰故障信号等指标的监测数据,引入偏离度实现监测指标的风险量化;其次,采用FCE法计算袋式除尘系统的风险状态,结合层次分析法(AHP)和变权理论对评价指标赋权,依据隶属函数和隶属度加权平均原则,量化基于偏离度的袋式除尘系统风险,获得系统风险评价结果;最后,运用某型号袋式除尘系统的监测数据验证模型。结果表明:当袋式除尘系统评价指标的监测值越趋近于报警阈值,且趋近于报警阈值的指标数量越多时,所处风险等级越高,评价结果与其实际运行情况具有相关一致性,验证了模型的有效性。In order to ensure the safe operation of bag dedust system and prevent the occurrence of dust explosion accident,a real-time quantitative risk evaluation model of bag dedust system was proposed based on deviation degree-FCE.Firstly,based on the monitoring data of the pressure difference between inlet and outlet of the dust,box temperature and lock-in ash discharge fault signal collected by the industrial Internet of Things sensor,the deviation degree was introduced to characterize the risk status of the monitoring parameters of the bag dedust system.Then,FCE was used to calculate the risk status of the bag dedust system.The analytic hierarchy process(AHP)and variable weight theory were combined to assign weights to the evaluation indicators.Based on the membership function and weighted average principle of membership degree,the risk of the bag dedust system was quantified by deviation degree,and the risk evaluation result for the bag dedust system was obtained.Finally,the monitoring data of a certain type of bag dedust system was used to verify the effectiveness of the model.The findings demonstrate that when the monitoring value of the evaluation indicators of the bag dedust system gradually approaches the alarm threshold,and the number of indicators approaching the alarm threshold increases,the risk level is higher.The evaluation results are correlated with the actual operation situation,thus validating the efficacy of the model.
