化学工业的生产特点及其在安全环保方面的特别要求决定了企业员工培训和学校学生的实习都不允许在真实的生产装置上动手操作,解决这一难题的途径之一是开发具有真实工业场景、工艺过程和操作参数与实际装置高度接近的仿真培训系统。按照工艺和设备具有典型代表性的思路,选择以环己烷氧化制环己酮生产装置中的环己烷精馏为对象开发仿真培训系统,针对三效精馏和组分多的复杂工艺,采用序贯模块法开发了整个系统的仿真模型,将各个独立的模型设计成独立的模块,模块之间通过变量进行连通,模块的连接关系按工艺连接关系搭接,仿真对象的有关数据来源于实际生产装置的运行参数,保证仿真速度的实时性和外部特性的逼真。整个系统包括了环己烷精馏装置生产工艺仿真软件,计算机控制系统(DCS)的实时仿真和仿真操作评价系统,是对环己烷精馏装置的全系统仿真。系统中开发平台的各项功能,提供了一套完整的开放式仿真平台。通过使用证明该系统能够有效模拟环己烷精馏的工艺现象和工艺操作步骤,真实地反映装置的开停车、生产及事故状态的动态效果,同时对工艺装置的安全分析和应急处理训练提供了一个良好的平台,可满足培训操作工和学生的需要,也可用于生产工艺的优化、诊断和控制方案方面的研究。
The production characteristics of the chemical industry and its special requirements in terms of safety and environmental protection determine that neither staff training nor student internships in the schools allow hands-on operation on real production equipment. One way to solve this problem is to develop a real industrial scene , Process and operating parameters and the actual device height close to the simulation training system. In accordance with the typical representative of the process and equipment ideas, choose cyclohexane oxidation cyclohexanone production unit for the development of simulation training system for the object of cyclohexane for the three-stage distillation and the composition of more complex processes, The simulation model of the whole system was developed by using the sequential module method. Each independent model was designed as an independent module. The modules were connected by variables. The connection of the modules was overlapped by the process connections. The relevant data of the simulation objects came from The actual operating parameters of the device to ensure real-time simulation speed and realistic external characteristics. The whole system includes the production process simulation software of cyclohexane rectification plant, real-time simulation and simulation operation evaluation system of computer control system (DCS), which is a system-wide simulation of cyclohexane rectification plant. System development platform for the various functions, provides a complete set of open simulation platform. By using this system to simulate the process of cyclohexane distillation process and process steps to truly reflect the device on and off, the production and the dynamic state of the accident, while the process of safety analysis and emergency training provided A good platform to meet the needs of training operators and students as well as research on optimization, diagnostics and control of production processes.
