| 摘 要： | 报道用低温等离子体的方法去除甲醛气体,主要考察了电场强度、进口浓度及填料对于甲醛气体去除效率的影响。实验研究结果表明,随着电场强度的增加,进口浓度的降低和在反应器中加有填料都会提高甲醛气体的去除效率。低温等离子体方法去除甲醛气体的机理可分为2部分:电子与污染物分子的直接碰撞和电场产生的活性粒子与污染物分子之间发生的一系列化学反应。

| Abstract: | This paper mainly discussed the treatment of formaldehyde with cold plasma. The effects of electric field intensity, initial concentration and padding on the removal mechanisms of formaldehyde were investigated.The results showed that the removal efficiency of formaldehyde could be enhanced with the high electric field intensity, low initial concentration and padding in the reactor. The removal mechanisms of formaldehyde were discussed as well based on the experimental results. The removal of HCHO depends on two mechanisms:collision between electrons and HCHO molecules,and reactions between gas-phase radicals and HCHO molecules. |
