摘要: 本文以介质阻挡放电的方式产生低温等离子体,利用低温等离子体技术成功地降解了常压状况下的气态CF2ClBr(哈隆1211).CF2ClBr含量为0.6%(V/V)的空气(1.013×105Pa)在放电10s的条件下,可使CF2ClBr达到95%的降解率.本文研究了常压状况下的CF2ClBr低温等离子体空间反应机理,以及CF2ClBr初始压力、电场强度和外加气体(He,N2和空气)分别对低温等离子体降解CF2ClBr的影响.Abstract: In this paper,the CF2ClBr (Halon 1211)vapor was atmospherically degraded by cold plasma engendered by dielectric barrier discharge. The pressure of CF2ClBr 6. 67� 102Pa, added air to 1. 013�105Pa after discharge for 10s, 95% of CF2ClBr was decomposed. The paper also studied the cold plasma gas phase chemical reaction mechanism of CF2ClBr at atmospheric pressure, and studied the influences of initial pressure of CF2ClBr, strength of electric field and alien gases (He, N2 and air)on the CF2ClBr degradation respectively by cold plasma method.
