【摘要】：在介質阻擋放電間隙填充介質顆粒,即填充床介質阻擋放電形式可以提升臭氧生成濃度和能量效率。因而設計了一種外玻璃管式填充床介質阻擋放電臭氧發(fā)生器,填充顆粒為玻璃微珠和金屬微粉混合物。實驗研究了填充床和空床放電的電學特性,以及產(chǎn)生臭氧濃度和能效與放電功率間的關系,并分析了介質損耗、冷卻水溫度、能流密度等因素的影響。實驗結果表明:填充床在低能流密度下相比空床放電生成臭氧質量濃度低約40%,而在高能流密度下質量濃度提升約30%,能效曲線先上升后下降,2 mm間隙填充的最大臭氧質量濃度達到60 g/m3;低溫冷卻水有利于臭氧生成,5℃冷卻水的效果比20℃質量濃度提升約17%;添加金屬微粉有利于增強放電、提升臭氧質量濃度和能效,提升幅度約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，
