介绍某公司焦化作业部7.63m焦炉所使用的单炭化室压力调节系统的特点和功能,并对其工艺原理、整体结构、网络通信、自动控制的实现以及HMI监控画面进行简述。

基于模糊推理的炉压自整定控制系统设计

针对矿热炉炉气回收过程中难以单纯依靠调节风机转速来保持炉压稳定实现全自动控制的问题,通过对现有控制方法的不足进行分析,提出通过改进软件算法,设计新的模糊自整定控制器来实现稳定炉压的目的。介绍了通过可编程控制器实现该算法的基本方法。通过程序改进有效提高了该套装置的自动化程度。

Based on the experimentation mathematical modeling and autoregulation realization for gas-collector pressure of coke furnace

Technical process and pressure control system of coke furnace were introduced.The mathematical model based on experimental method of gas-collector pressure wasproposed.To a certain extent, it is more reliable and dependable than mechanism method.Manufacturing process and experimental modeling can be finished at the same time, andfurthermore, the mathematical model can be established automatically.The realization algorithmof the total decoupling and on the line's modification for model value plays an importantrole in improving regulating quality.Finally, the DCS network structure to realizethe process was introduced.The control results show that the regulator can get reliableand robust performance.
