Research on Development of Nox Removal Reactor by Packed-Beads Method with Superimposing Barrier Discharges.

我们已经研究了氮氧化物的清除是通过超级安装屏障放电来清除柴油发动机的外部气体。一些超imposing barrier discharges reactors已被提议，超imposing barrier discharges方法对于NOx清除是有用的。我们建议在缺口区域填充反应堆，就像玻璃板和明显的障碍珠子一样。我们希望表面和无声的放电完全在同一个空间产生。在本研究中，反应堆中的新珠子对氮氧化物去除性能的影响已被实验调查。作为一个参数的电泳配置，填充的屏障珠子对NOx排出的影响，层和相对的电常数的数量也是实验性的调查。实验是用于干燥的N-D22-D2/NO气体的流动速率为400至1400 mL/min。样品流气体中的NO和NOx的情况是由化学型Nox分析仪测量的。 ...

We have been investigated NOx removal by superimposing barrier discharges for exhaust gases from diesel engine. Several superimposing barrier discharges reactors has been proposed, the superimposing barrier discharges methods are useful for NOx removal. We proposed a reactor in which the gap area is filled as single layer of glass plates and sherical barrier beads. We expect that surface and silent discharges are generated simultaneously in the same space. In this study, the effect of barrier beads on the NOx removal performances by new bead in reactor is experimentally investigated. The effect of filling barrier beads on the NOx removal as a parameters are electrode configuration, the number of layer and relative dielectric constant is also experimentally investigated.Experiments are conducted for the dry NィイD22ィエD2/NO gas for flow rate is from 400 to 1400mL/min. The concentrations of NO and NOx in the sample gas are measured by a chemiluminescence type Nox analyzer at upstream and do … More wnstream of the reactor. The parallel plate electrodes arrangement with an effective discharge area of 30 mm x 300 mm and discharge gap filled with barrier beads as single layer was used for discharge unit. The glass beads, AlィイD22ィエD2OィイD23ィエD2 beads, CaTiOィイD23ィエD2 beads, SrTiOィイD23ィエD2 beads and BaTiOィイD23ィエD2 beads were used as the filling barrier beads.As the results, the filling barrier beads as single layer obtain an improvement removal energey yield. It is the reason why the filling barrier beads varies electric field. Moreover, the covering with barrier plate, filling barrier beads as single layer and contacting with plate and beads as the distinction of this reactor are most effectively for NOx removal. The NO removal rate increases with increasing relative dielectric constant up to 330 and become saturated over 330 at the same discharge power. This result is caused by discharge current on each condition. Becasuse, the influence of relative dielectric constant upon NO removal rate and discharge current shows similar tendency. Less
