摘要:

传统搅拌反应器运行模式匹配度较差,缺乏对搅拌装备的智能化诊断、控制和匹配能力监测。近年来,工业互联网的兴起引起了各个行业内巨大的研究兴趣,并取得了相对可喜的进展。本文首先概述了工业物联网兴起的背景及其特征优势,然后简述了搅拌反应器智能化需解决的关键技术难题,而后采用工业物联网技术,对表征搅拌反应器内部物料混合状态的时变信号进行数据智能化采集、分析和处理,并预测设备内部物料未来状态的变化趋势。结合流体混沌混合特性、宏观混合行为以及搅拌反应器结构参数和操作参数进行大数据分析,形成了智能监测与混沌同步体系,并建立搅拌反应器智能监测的操作平台,主要包括风险动态管控、在线监测预警和实时反馈控制三大功能模块。最后,总结了该搅拌反应器智能终端在化工领域存在的挑战,并且对未来发展方向及应用前景进行了展望。希望通过本文能吸引化工方面不同研究背景的学者进入这个多学科交叉领域,共同为推动节能减排、发展智能化工装备与安全做出一定贡献。

Abstract:

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.

Key words: stirred reactor, intelligent, industrial internet of things (IIoT), chemical, equipment
