项目摘要
The aim of this research which was continued for three years is to establish the environmental air control system, that is, the decomposition system of diluted gaseous organic compounds in environmental air by using a alumina-based ceramic reactor with high frequency surface discharge on the inner wall of a cylindrical reactor. The non-equilibrium low temperature plasma prosuced by the surface discharge is found to be very effective to decompose many voltile compounds, such as CFC22 (chloro-difluorohydromethane : CHClF_2), CFC113 (trichlorotrifluoroethane : CF_2ClCFCl_2) and other halogenated organic compounds (trichloroethylene, 113-truchloroethane, 12-dichloroethane, dichloromethane). Inevery case, very high decomposition performance by the device was very well and more than 90% of dilute contaminants in air was removed. Other acetone in air was also decomposed by the surface discharge plasma as normal contaminated VOC.Acetone is found to be very difficult to be destroyed by the discharge. Alcohol (isopropylalcohol) is found to be oxidized by the discharge and some part is changed to acetone. By GCMS (Gas-Chromatograph Mass Spectrometer) analysis, the intermediate halogenated compounds and phosgen are observed when the decomposition is half (-50% decomposition rate). However, at the high decomposition rate of 95% or more, the intermediate products are decomposed and residual gasses are chlorohydrogen and carbon-dioxide. Production of NOx by the air discharge is not yet observed. UV is also found to be effective to decompose trichloroethylene.
本研究历时三年,目的是利用圆柱形反应器内壁高频表面放电的氧化铝陶瓷反应器,建立环境空气控制系统,即环境空气中稀释气态有机化合物的分解系统。表面放电产生的非平衡低温等离子体对CFC22(氯-二氟氢甲烷:CHClF_2)、CFC113(三氯三氟乙烷:CF_2ClCFCl_2)和其他卤化有机化合物(三氯乙烯、113-三氯乙烷、12-二氯乙烷、二氯甲烷)等挥发性化合物的分解非常有效。在每一种情况下,该装置的分解性能都非常好,空气中90%以上的稀释污染物被去除。空气中的其他丙酮也被表面放电等离子体分解为正常污染的VOC。人们发现丙酮很难通过放电被破坏。发现醇(异丙醇)被排出物氧化,部分变为丙酮。通过气相色谱-质谱联用(GCMS)分析,在分解一半(-50%分解率)时,观察到中间卤代化合物和光能。但在95%以上的高分解率下,中间产物被分解,残余气体为氯氢和二氧化碳。空气排放产生的氮氧化物尚未被观察到。紫外线也被发现能有效地分解三氯乙烯。
