| 摘 要： | 实验设计了一种新式小型臭氧发生装置,该装置采用介质阻挡放电的方式产生臭氧.研究了电极结构、气体流量、放电时间、放电电压、各电极的电流电压峰值、是否添加氧气等与产生臭氧浓度之间的关系.结果表明:放电间隙为2.0 mm,有效长度为500 mm的同心圆柱体电极的放电效果最好;串联相同电极的放电效果好于并联电极的放电效果;在电压一定时,臭氧产量随空气量的增加而减少;当放电气体中加入氧气时,臭氧的浓度明显地增高;随着放电时间的增加,臭氧的浓度会略微下降,最后趋于一个常值;臭氧的产量与电极的电流峰值具有相同的变化趋势,而与电压峰值的变化相反.

| Abstract: | A novel ozone generator was introduced in the present paper.The novel ozone generator produced ozone by dielectric-barrier discharge method.The parameters that affect the concentration of the generated ozone,such as the geometry of electrode system,gas flow rate,discharge time,discharge voltage,peak current and voltage of electrodes and the content of oxygen,were discussed,respectively.The results indicated that the coaxial cylinder electrode with discharge space 2.0 mm,discharge length 500 mm had the best ... |
