| 摘 要： | 在介质阻挡气体放电等离子体条件下，研究阻挡介质特性对NO脱除的影响规律。首先建立了介质阻挡放电等离子体脱硝试验系统，实验研究了Al2O3、CaO、MgO和玻璃等不同介质阻挡下NO的脱除效果，并对此影响规律进行了理论分析。实验结果及理论分析表明，不同阻挡介质所形成的气体放电的电场强度不同，提供给活性粒子的能量也不同，从而对NO的脱除效果具有不同的影响。

| Abstract: | The impact of dielectric characteristics on NO removal is studied under the presence of dielectric barrier discharge plasma. First, a NO removal test system with the use of the dielectric barrier discharge plasma was set up. An experimental study was conducted of the NO removal efficiency by using various dielectrics, such as Al 2O 3, CaO, MgO and glass, etc. Then, a theoretical analysis was performed of the mechanism of such an impact. The results of experiment and theoretical analyses indicate that the electric field intensity of gas discharge formed by various barrier dielectrics are different with the energy provided to activated particles also being different. This results in a different influence on the NO removal rate. |
