为了提高焦化厂配煤控制的精度,提出了基于PID的原理的的配煤控制系统。根据对焦化厂配煤选料的要求,详细设计了自动配煤系统的组成结构,对配煤系统的核心控制部分采用PID控制策略,提高了配煤系统的自动化程度和精度。重点分析了PID控制器的设计方法,并给出了应用于焦化厂配煤控制的PID参数。解决了传统配煤控制方案精度低、配煤过程长而导致焦化厂生产的产品质量不稳定问题,大大提高焦化厂配煤选料系统的自动化程度和智能化程度,有效的控制焦化厂产品的质量。

To improve the accuracy of coal blending control in coking plant, the coal blending control system is proposed. The composition structure of automatic coal blending system is specifically designed according to the requirements of coal blending and material choice in coking plant. By applying PID control strategy to the core control section of coal blending system, the automation and accuracy of coal blending system is thoroughly improved. This paper focuses on the design methods of PID controller, gives the PID parameters of coal blending control in coking plant. The proposed system could fairly solve the low accuracy and long coal blending process of traditional coal blending control system, for these flaws would result in unstable product quality of the coking plant. Experiment indicates that the proposed system could greatly raise the automation degree and intelligence level, and effectively control the products quality of the coking plant.
