【摘要】：在介质阻挡放电间隙填充介质颗粒,即填充床介质阻挡放电形式可以提升臭氧生成浓度和能量效率。因而设计了一种外玻璃管式填充床介质阻挡放电臭氧发生器,填充颗粒为玻璃微珠和金属微粉混合物。实验研究了填充床和空床放电的电学特性,以及产生臭氧浓度和能效与放电功率间的关系,并分析了介质损耗、冷却水温度、能流密度等因素的影响。实验结果表明:填充床在低能流密度下相比空床放电生成臭氧质量浓度低约40%,而在高能流密度下质量浓度提升约30%,能效曲线先上升后下降,2 mm间隙填充的最大臭氧质量浓度达到60 g/m3;低温冷却水有利于臭氧生成,5℃冷却水的效果比20℃质量浓度提升约17%;添加金属微粉有利于增强放电、提升臭氧质量浓度和能效,提升幅度约25%。
[Abstract]:Filling dielectric particles in the gap of dielectric barrier discharge, that is, the form of dielectric barrier discharge in packed bed, can improve the concentration of ozone generation and energy efficiency. Therefore, an external glass tube packed bed dielectric barrier discharge ozone generator is designed. The filled particles are a mixture of glass bead and metal powder. The electrical characteristics of packed bed and empty bed discharge and the relationship between ozone concentration, energy efficiency and discharge power are studied experimentally. The effects of dielectric loss, cooling water temperature and energy flow density are analyzed. The experimental results show that the mass concentration of ozone in packed bed is about 40 parts lower than that in empty bed discharge at low energy flow density, while the mass concentration increases about 30% at high energy flow density. The energy efficiency curve rises first and then drops down to the maximum odor filled with 2 mm gap. The oxygen concentration is 60 g / m ~ 3; the effect of low temperature cooling water is about 17% higher than that of 20 鈩，
