中文摘要: 流程工业是对生产过程为连续或半连续的工业企业的总称,氧化铝生产是连续过程,属典型的流程工业,它不仅对流程中各工序本身有实现自动控制的需求,而且与其上下游工序的物流在质与量等方面都有直接的关联,必须从整个生产流程的全局出发,对各工序的控制需求和信息交换需求进行优化。氧化铝生产过程比较长,包含原矿、溶出、沉降、分解、蒸发、焙烧几个工序,需要从各个工序逐步突破,该优化控制系统以模糊控制及神经元网络为核心,在无需建立精确数学模型的情况下,实现性能优异的自适应和人工智能。通过数据相关性分析,结合生产工艺,运用模糊控制、规则自学习等技术,解决工艺过程工况复杂、非线性、变时滞性、多变量耦合等问题,对产品产量、粒度等关键工艺指标进行优化控制。该系统可以有效保证工艺稳定运行以及各工段生产质量指标合格的前提下有效提高流程的工作效率、节约能源损耗、减少操作人员数量和工作强度。尤其在提高台时处理量、减少现场异常停车、磨机涨肚、旋流器跑粗、拉稀等异常工况的发生效果显著。
Abstract:The process industry is a general term for the industrial enterprises whose production process is continuous or semi continuous. Alumina production is a continuous process, which is a typical process industry. It not only has the demand of realizing automatic control for each process itself, but also has a direct relationship with the logistics of upstream and downstream processes in terms of quality and quantity. It must start from the overall situation of the whole production process and focus on the quality and quantity of each process Control requirements and information exchange requirements are optimized. Alumina production process is relatively long, including raw ore, dissolution, sedimentation, decomposition, evaporation and roasting processes, which need to be gradually broken through from each process. The optimization control system takes fuzzy control and neural network as the core, and realizes self-adaptive and artificial intelligence with excellent performance without establishing accurate mathematical model. Through the data correlation analysis, combined with the production process, using fuzzy control, rule self-learning and other technologies to solve the complex process conditions, non-linear, variable time delay, multi variable coupling and other issues, and optimize the product output, granularity and other key process indicators. The system can effectively ensure the stable operation of the process and the qualified production quality indicators of each section, and effectively improve the work efficiency of the process, save energy consumption, reduce the number of operators and work intensity. Especially, it can improve the handling capacity of the machine, reduce the abnormal stop of the site, increase the belly of the mill, run rough of the hydrocyclone and draw thin.
