气味控制对于确保舒适的生活环境变得越来越重要。本文报道了一种用于气味控制的阻隔式填料床非热等离子体反应器的详细特性研究的实验结果。该等离子体反应器已广泛应用于挥发性有机物（VOC）的分解和NO的还原。电抗器由低成本的60Hz交流电源供电。在不同的实验条件下，研究了副产物的去除效率和浓度。在干燥的环境中，主要气味成分NH3完全分解，反应副产物生成最少（最大N2O浓度为10ppm）。加入水分会使分解恶化。在填充床等离子体反应器中，确定了完全去除NH3所需的最小停留时间。球团直径对去除趋势影响不大，反应器的pet形成优于无声电晕。在气流中加入其他气味组分如CH3CHO对NH3的去除效率影响不大。
Odor control has gained importance for ensuring a comfortable living environment. In this paper, the authors report the experimental results of a study of the detailed characteristics of a barrier-type packed-bed nonthermal plasma reactor used for odor control. This plasma reactor has been widely used for volatile organic compound (VOC) decomposition and NO, reduction. The reactor is energized by a low-cost 60Hz AC power supply. Removal efficiency and the concentrations of byproducts are studied under various experimental conditions. The complete decomposition of the main odor component, namely, NH3, is obtained with minimal reaction byproduct formation (maximum N2O concentration, 10ppm) in a dry environment. The decomposition is deteriorated by the addition of moisture. The minimum residence time is determined for the complete removal of NH3 in the case of the packed-bed plasma reactor. The pellet diameter has little effect on the removal tendency, and the reactor pet-formed better than a silent corona. Mixing another odor component such as CH3CHO into the gas stream has little effect on the NH3 removal efficiency.
