The traditional stirred reactor operation mode is poorly matched,and there is a lack of intelligent diagnosis,control and matching capability monitoring of stirred equipment.In recent years,the rise of industrial internet has aroused great research interest within various industries,and relatively promising progress has been made.This paper first outlined the background of the rise of industrial internet of things(IIoT)and its characteristic advantages.Then,the key technical challenges to be solved for the intelligence of stirred reactors were briefly described.The industrial internet of things technology was used to intelligently collect,analyze and process the time-varying signals characterizing the mixing state of the material inside the stirred reactor,and to predict the trend of the future state of the material inside the equipment.Combined with the fluid chaotic mixing characteristics,macroscopic mixing behavior,and big data analysis of stirred reactor structure parameters and operation parameters,an intelligent monitoring and chaos synchronization system was formed,and an operation platform for intelligent monitoring of the stirred reactor was established,which mainly included dynamic control of risk,online monitoring and early warning,and real-time feedback control.Finally,the challenges of this stirred reactor intelligent terminal in the chemical industry were summarized,and the future development direction and application prospects were prospected.It is hoped that this paper can attract scholars with different research backgrounds in chemical industry to enter this multidisciplinary crossover field and make some contributions to promote energy saving and emission reduction,and develop intelligent chemical equipment and safety together.
