摘 要: 采用雾化加湿与等离子体相结合的方法,一方面高效产生对人体健康有利的负氧离子,去除飘尘污染; 另一方面控制副产物浓度使其低于国家健康标准。通过超声波雾化方法产生大量的水汽溶胶,流经线筒式电 极结构的等离子体发生器,施加高压正弦电压产生等离子体。研究结果发现:1)水汽溶胶可以大幅度提高负 氧离子的产生效率;2)对飘尘有良好的去除效果,随电压的提高去除时间缩短;3)雾化加湿会大幅度降低 O3 和NO2 浓度,在电压幅值低于8 kV 情况下,这些副产物在等离子体发生器出口位置浓度低于国家标准。
关 键 词: 电气工程;高电压技术;等离子体;负氧离子;空气净化;臭氧

Abstract: In this paper, we present a novel approach by combining the cold plasmas with water vapor sol to benefit the production of oxygen anion which is good for health, with the removal of floating dust, and the control of by-products. The water vapor sol generated by ultrasonic atomization flows through a line-cylinder reactor, on which a sinusoidal high-voltage is applied for the plasma generation. It is found that: 1) the water vapor sol can greatly improve the production efficiency of oxygen anion; 2) the removal of floating dust is efficient, and the efficiency increases with the applied voltage; 3) the concentrations of O3 and NO2 are much lowered by the water vapor sol, and they are lower than the national standard levels when the applied voltage is not higher than 8 kV.
