摘　　要：为改善冷焦溢流水温度控制质量,针对冷焦溢流水的来水量及其温度的不确定性特点改变控制策略,提出在增设换热器的基础上,将原来的单回路闭环反馈控制改造为双回路的前馈-反馈复合控制。介绍了复合控制系统设计方案及系统仿真效果。现场采用改造后的冷焦溢流水处理工艺,混合冷却后冷焦溢流水的出水口温度可稳定在设计的85℃左右。In order to improve the quality of the temperature control of the overflow water of the cold coke plant,the control strategy is changed according to the uncertainty of the inflow and temperature of the overflow water.On the basis of adding heat exchanger,the original single loop closed-loop feedback control is transformed into a double loop feed forward-feedback compound control.The design scheme and simulation effect of the composite control system are introduced.The improved treatment process of coke cold overflow water is adopted on site,after mixing cooling,the outlet temperature of coke cooling overflow water can be stabilized at about 85℃.
