为了改善低温等离子体(NTP)技术自身不足所带来的局限性,拓宽其在去除恶臭污染方面的应用,将催化剂与NTP联用并对比两者不同的耦合方式对H2S的降解效果,即比较内置式结构和外置式结构的净化机制和处理效果.结果表明,内置式反应系统中,催化剂颗粒与反应器壁面之间形成的接触点增强了整个系统的放电过程,而外置式耦合系统放电产生的高能电子产量较低.此外,与单独NTP系统相比,内置式耦合系统对H2S有截留作用,使其与活性物质充分接触,提升了放电效率,在35 V时输出效率可达 64.79%.
EFFECT OF TREATING MALODOROUS GASES BY NON-THERMAL PLASMA COUPLING CATALYST
To improve the limitation of non-thermal plasma(NTP)technology and broaden its application in the treatment of odorous gas,Cu doped catalyst was combined with NTP technology.The H2S degradation efficiency,influence of coupling methods,internal structure and external structure were researched comprehensively.In addition,the role of catalyst and synergetic mechanism were approached.The results showed that the contact points between the catalyst particles and the reactor wall enhanced the discharge process,while the output of high-energy electrons was lower in external structure system.Compared with the single NTP system,the built-in coupling system could cut off the H2S and make it contact with the active substance sufficiently,which improved the discharge efficiency,and the output efficiency could reach 64.79%at 35 V.
