设计了一种集气管压力的智能协调控制方案,解决焦炉集气管压力之间耦合严重,稳定性较差,极易出现压力振荡现象。综合考虑多集气管及风机、回流的特性,集气管翻板阀采用双模式PID算法,风机或回流阀进行整体吸力的协调控制,同时引入了振荡检测机制,并对压力振荡进行抑制。该控制方案的效果已在焦化企业现场得到了实践验证,并在多个现场应用。

In the gas collection process of coke ovens, the pipes have high coupling relations, which result in the unstableness of the pressure. The pressure oscillation phenomena are frequently reported in practical productions. This paper proposed an intelligent collaboration control solution, which take the characteristics of gas collection pipes, fan and the recycle pipe into consideration. Dual-mode PID algorithm is utilized in the gas collection pipe pressure control formulation and the fan speed and recycle valve are manipulated to keep the entire lfow power. Pressure oscillation detection is introduced here to prevent severe lfuctuation of the pipe pressure. The proposed method has been validated and is widely used in the coke production plants.
