采用数值模拟方法，结合标准k-ε模型、组分输运模型和层流有限速率模型，以某特定结构的臭氧投加设备为研究对象，对影响臭氧氧化工艺过程的相关因素进行深入分析。研究结果表明，NO的氧化效率随着烟气中O₃/NO摩尔比的增加而升高，但增加速率逐渐降低；当O₃/NO摩尔比为1、烟气温度为100~250℃时，NO的氧化效率随着温度的升高而降低；烟气中SO₂浓度对NO的氧化效率没有明显的影响。

Taking the ozone injector with a specific structure as study object,the factors that affect the ozone oxidation process are analyzed deeply by means of numerical simulation method combining with standard k-ε model,species transport model and laminar finite-rate model.Analysis result shows that the oxidation efficiency of NO raises with the increasing molar ratio of O₃/NO in flue gas,but the growth rate decreases gradually.The oxidation efficiency of NO will decrease with the increasing temperature when the temperature of flue gas locates in the range of 100-250℃ and the molar ratio of O₃/NO is set as 1.Meanwhile,the existence of SO₂ in flue gas has no obvious impact on oxidation efficiency of NO.
