摘　　要：以某火电厂660MW机组石灰石/石膏湿法烟气脱硫系统为对象,在研究脱硫塔内气液传质、化学反应机理及进行合理简化假设的基础上,采用集总参数法和模块化建模方法,建立了其喷淋式脱硫塔的动态数学模型;通过稳态检测和动态扰动试验验证了模型的正确性,为开发该电厂脱硫系统实时培训仿真模型奠定了基础。The wet limestone-gypsum flue gas desulphurization system for 660 MW units of a thermal power plant is taken as the object, based on the study of the mass transfer between the gas phase and the liquid phase, chemical reaction mechanism in desulphurization tower and reasonable simplified hypothesis, the turbulent mathematical model of the spray type tower is developed by the methods of concentration of parameters and module modeling. The model is validated by the test of stable state and the turbulent experiments, which can be used as the basis for developing the real training simulation model of the desulphurization system.
