Research and Integrated Application of Intelligent Technology for Cement Production

智能化技术的研发和应用是传统水泥制造业走向自动化的必经之路。近年来,众多水泥企业在生产智能化方面作出诸多研究,但仍存在控制回路不完善、智能控制水平低、智能决策未健全等问题。本文以水泥绿色、高性能生产和减负增效为目标,经过科技攻关和工程化验证,首次构建了集生产过程数据采集、工况智能辨识、多策略智能优化控制、智能生产管理于一体的水泥生产智能化体系结构;开发了多个数据处理与融合软件,突破了生料成分、烧成带温度、水泥粒度分布信息准确提取的瓶颈,状态识别准确率达80%以上;研发全流程优化控制技术并编制相应的控制软件,实现水泥生产的智能优化控制。本文所研究的技术已成功应用于百余条生产线,包括水泥巨头拉法基集团、俄罗斯及南非等国家的水泥企业、中国建材集团、山水集团等,社会效益显著。

One of the necessary approaches for the cement industry to transition from traditional manufacturing to intelligent manufacturing is the research and application of intelligent technology.In recent years,many cement enterprises have made much research on production intelligence,but there are still problems such as imperfect control loop,low level of intelligent control,and unsound intelligent decision-making.In this paper,with cement green,high-performance production,and load reduction and efficiency as the goal,after scientific and technological research and engineering verification,we have for the first time constructed a cement production intelligent system structure integrating production process data acquisition,intelligent identification of working conditions,multi-strategy in intelligent optimization control and intelligent production management.We developed multiple data processing and fusion software,and broke through the bottleneck of accurately extracting the information on the composition of raw materials,temperature of the firing zone,and the distribution of cement particle size,with an accuracy of state identification of up to 10.5 percent.It has broken the bottleneck of raw material composition,firing zone temperature,and cement particle size distribution information extraction,and the accuracy of state identification reaches more than 80%.This paper has also developed the optimization control technology of the whole process and compiled the corresponding control software to realize the intelligent optimization control of cement production.The technology developed in this paper has been successfully applied to more than 100 production lines,including cement giant Lafarge Group,cement enterprises in Russia and South Africa,China National Building Material Group,Shanshui Group,etc.,with great social benefits.
