等离子体气态污染物控制技术的研究进展

Study Advances about Plasma Control Technology for Gaseous Pollutants

等离子体化学过程在增强氧化能力、促进分子离解以及加速化学反应等方面具有较高的效率,因此,近年来利用等离子技术对气态污染物的氧化分解研究受到了广泛的关注。简述了在气态污染物处理过程中所应用的各种等离子体反应器及其基本运行参数。较为全面地介绍等离子体技术在脱硫、脱硝以及降解挥发性有机物(VOCs)方面的研究,重点分析了国外等离子体VOCs控制技术的发展,最后提出了等离子体气态污染物控制技术未来的发展方向。

Plasma has good effect on strengthening oxidation ability, improving molecule dissociation and hastening chemical reaction during the treatment of pollutants, so the study about using plasma technology to treat gaseous pollutants is being paid more attention in recent years. Various plasma reactors and their basic operation parameters are introduced briefly, and it is detailed to analyze the study about DeSO2, DeNOx and DeVOCs using plasma technology, especially to DeVOCs at broad. At last, the development of plasma pollution controlling technology is brought forward.
