| 摘 要： | 在自行设计的内置紫外光-鼓泡器中,利用UV/H2O2高级氧化工艺湿法脱除燃煤烟气中的NO气体。主要对紫外光强度、H2O2初始浓度、NO初始浓度以及烟气总流量对NO脱除效率的影响进行了考察。研究结果表明,在实验范围内,NO脱除效率随着紫外光强度和H2O2初始浓度的增加而增加,但当达到一定值后,NO脱除效率的增加幅度均变得相对平缓;NO脱除效率随着NO初始浓度以及烟气总流量的增加呈近似线性减小。通过离子色谱对液相离子产物进行了定性与定量检测,并对NO中的氮元素进行了物料平衡计算,在此基础上对NO脱除路径与产物形态进行了理论分析。

| Abstract: | Wet removal of NO from coal-fired flue gas by UV/H2O2 advanced oxidation process was investigated in a self-designed UV-bubble reactor.Several main influencing factors including UV intensity,H2O2 initial concentration,NO initial concentration and flue gas total flow on the removal efficiencies of NO were studied.The results show that the NO removal efficiency increases with increasing UV light intensity and H2O2 initial concentration.When they reach a certain value,the growth rate of the NO removal efficien... |
