论文摘要
在这项工作中，已经评估了臭氧O3紫外线（UV）光反应堆对气相氧化的潜力。为此，已经对连续搅拌的储罐反应堆（CSTR）进行了数值模拟，以分析二氧化硫SO2去除。化学动力学已与具有五个不同辐射模型的紫外灯产生的辐射强度分布的建模。进行了网格收敛研究和对某些辐射模型使用的离散点光源数量的优化。还已经分析了停留时间和反应器大小对去除SO2的影响。总体而言，在优化条件下在O3-UV反应堆中减少SO2的结果表明，这种方法适合可持续的空气清洁应用。
The potential of a combined ozone O3 ultraviolet (UV) light reactor for gas-phase oxidation of flue gas pollutants has been evaluated in this work. For this, numerical simulations of a continuously stirred tank reactor (CSTR) have been performed for the analysis of sulfur dioxide SO2 removal. Chemical kinetics have been coupled with modeling of the radiation intensity distribution produced by a UV lamp with five different radiation models. A grid convergence study and an optimization of the number of discrete point light sources employed for some of the radiation models was carried out. The effect of residence time and reactor size on the removal of SO2 have also been analyzed. Overall, results for the abatement of SO2 in an O3-UV reactor under optimized conditions suggest that this approach is suitable for sustainable air cleaning applications.
