传统的生物氧化预处理过程温度控制算法参数整定过程复杂,且受干扰后会使控制漂离最佳状态。针对这一问题,以某金矿生物氧化预处理工艺为研究背景,分析了氧化槽内生物氧化反应热、冷/水阀循环热、氧化槽与外界发生热传递的流失热之间的平衡关系,构建了以冷/热水调节阀开度为控制目标,以环境温度、矿浆温度、冷/热水水温为状态参数的温度控制模型。经过验证,该模型有效地解决了传统温度控制系统存在的问题,实现了氧化槽温度的稳定控制。

The parameter tuning process of temperature control algorithm in conventional biological oxidation pretreatment process is complicated. The control effect of the temperature control algorithm is easily drifted away from the best state after being interfered. A bio-oxidation pretreatment process was used as research background. The bio-oxidation reaction heat of oxidation tank, the cycle heat of hot/cold water valve and the balance of heat loss between oxidation tank and the outside world were analyzed. Through the analysis a temperature control model was established. Hot/cold water valve opening degree is the control target in the proposed model. Ambient temperature, slurry temperature and hot/cold water temperature are the state parameters. The results of simulation proved that the model has effectively solved the traditional problems of temperature control system and achieved a stable temperature control of the oxidation tank.
