摘要:
利用反应动力学模拟开展了电源特性对脉冲介质阻挡放电条件下NOx净化脱除规律的影响研究,对高能电子参与的N2、O2和O的电离解速率常数采用碰撞反应截面方法求取,并通过数值模拟获得了反应器内活性基元、NO及其副产物随时间的变化规律.模拟结果表明动力学模型较好地反映了活性基团浓度的脉冲变化趋势,电源特性对NO的脱除具有明显的影响,提高纳秒级脉冲峰宽及电源脉冲放电频率,均可以有效改善NO的净化效果,这些结果对等离子体氮氧化物净化装置的优化有一定的指导作用.
Abstract:
In th is paper, the impacts of the characteristics o f the pow er supply on the remova l o fNOx under the d ie lectr ic barrier d ischarge a re inv estig ated by chem ical k inetic simu la tion theoretica lly. The reaction ra te constant of the ion ization o f N2、O2 and O by e lec tron- im pact d issoc ia tion is obta ined by the co llision cross section me thod. The concentrations o f ac tive ions, atom s, free rad ica ls and NO byproducts are predicted according to the resident tim e in p lasm a reac to r. The simu la tion resu lts show that the kineticm ode l reflects the gene ra tion o f the various active radicals proper ly. The impact o f the characteristic of the powe r supply on NOx rem ova l is obv ious. Increasing the pos itive pulse tim e and the frequency o f pu lsed discha rge w ill improve the remova l o fNO. Th is w ork w ill play an institutive role in optim iz ing theNO pur ification dev ice.
