【摘要】 介质阻挡放电是大气压下产生低温等离子体的常用方法,在等离子体脱硫脱硝领域有着良好的应用前景。低温等离子体反应器的电极配置形式是影响反应器的放电特性及脱硫脱硝效率的主要因素之一。因此本文对线-板式介质阻挡放电反应器电极配置进行了优化研究。实验中采用圆筒式低温等离子反应器,对介质阻挡放电及NO脱除效率进行研究。考察了电压、内电极形状、气体种类对介质阻挡放电效果的影响。并研究了电压、氧气含量、进口NO浓度对NO脱除率的影响。作为应用基础研究,本文对介质阻挡放电等离子体反应器结构优化及提高脱硫脱硝效率有一定的参考价值。更多还原

【Abstract】 Dielectric barrier discharge is a common method of producing non-thermal plasma at atmospheric pressure.DBD has a good prospect in the field of removal of sulfur dioxide and nitric dioxide with non-thermal plasma.The electrode configuration of nonthermal plasma reactor is one of the main factors which affect reactor discharge characteristics and the De SO₂/NOx efficiency.So in this paper,the electrode configuration of the wire-plate DBD reactor has been optimized.The results provide the theoretical gist for the optimization and manufacture of the wire-plate DBD plasma reactor.In this experiment,the cylindrical plasma reactor was used in order to discuss the effect of dielectric barrier discharge.And the different reacting systems including the power supply、O₂、NO which affect the removal rate of NO are discussed.As a basic application research,the results in this paper are reference for plasma reactor design and improving the De SO₂/NOx efficiency.更多还原
