| 1 | A review on application of dielectric barrier discharge plasma technology on the abatement of volatile organic compounds显示文摘Volatile organic compounds(VOCs)released from the waste treatment facilities have become a significant issue because they are not only causing odor nuisance but may also hazard to human health.Non-thermal plasma(NTP)technologies are newly developed methods and became a research trend in recent years regarding the removal of VOCs from the air stream.Due to its unique characteristics,such as rapid response at room temperature,bulk homogenized volume,high reaction efficiency,dielectric barrier discharge(DBD)plasma technology is considered one of the most promising techniques of NTP.This paper reviews recent progress of DBD plasma technology for abatement of VOCs.The principle of plasma generation in DBD and its configurations(electrode,discharge gap,dielectric barrier material,etc.)are discussed in details.Based on previously published literature,attention has been paid on the effect of DBD configuration on the removal of VOCs.Effect of various process parameters such as initial concentration,gas feeding rate,oxygen content and input power on VOCs removal are also considered.Moreover,the role of catalysis and inhibitors in VOCs removal by DBD system are presented.Finally,a modified configuration of the DBD reactor,i.e.double dielectric barrier discharge(DDBD)for the abatement of VOCs is discussed.It was suggested that the DDBD plasma reactor could be used for higher conversion efficiency as well as for avoiding solid residue deposition on the electrode.These depositions can interfere with the performance of the reactor. | Wenjing Lu Yawar Abbas Muhammad Farooq Mustafa Chao Pan Hongtao Wang | 2019 | Frontiers of Environmental Science & Engineering2019，13，2： | 6 |
| 2 | 不同介质下氦DBD等离子体特性数值模拟显示文摘为深入理解氦气氛围电介质材料对介质阻挡放电(dielectric barrier discharge,DBD)的电气特性影响,建立单介质覆盖高压电极的1-D流体模型,通过有限元分析法进行数值模拟,采用频率10.0 k Hz、幅值2.0 kV的正弦交流激励,研究了亚稳态氦原子数密度、电子密度、电场强度的时空变化特性,以及介质材料、放电间隙和介质厚度对介质阻挡放电特性的影响。仿真结果表明:随着介电常数增加,电子密度和氦离子数密度均增大,同时介质表面累积的电荷密度增加,放电强度增强,碰撞功率损失变大;随着介质厚度增加,介质表面累积的电荷密度和空间电荷密度降低,碰撞功率损失逐渐下降,同时电子温度降低;随着放电间隙增大电子密度降低,同时介质表面累积的电荷密度、碰撞功率损失降低,放电强度减弱。 | 李平 徐俊生 陈兆权 许桂敏 | 2020 | 高压电器2020，56，11： | 1 |
| 3 | 不同气压下氩气介质阻挡放电γ过程仿真显示文摘为了研究在氩气不同气压下对介质阻挡放电(DBD)的电气参数和放电特性的影响,利用有限元分析建立大气压下氩气中的二维轴对称板-板电极放电等离子体模型,并对放电过程进行求解,通过仿真得到放电过程中的电势、电子温度、电子密度及氩离子数密度随着空间位置变化的波形。仿真结果表明,介质阻挡放电的特性变化与放电环境气压变化有关,随着气压的增加,气压在一定范围内,电势、电子温度、电子密度都下降,且电势空间分布的变化与电子密度相关。 | 李平 徐俊生 陈兆权 | 2019 | 安徽理工大学学报(自然科学版)2019，39，1： | 1 |
| 4 | ODS类物质绿色处理工艺研究进展显示文摘主要总结了有关ODS(臭氧层破坏物质)无害化处理及资源化转化利用的最近研究结果。迄今,有关ODS、HFCs的处理技术主要包括:1)热焚烧和热裂解;2)等离子体技术;3)气相加氢脱卤;4)催化加氢脱卤;5)催化水解;6)资源化利用。由于此类物质性质稳定,且往往可以作为灭火剂,因此采用热裂解或焚烧处理往往需要极为苛刻的反应条件,处理的成本和设备投资往往较高。等离子体工艺的设备投资和运行成本是一般热焚烧工艺的3-5倍,因此也不是最佳选择。而对于加氢脱卤,由于其有害副产物较多,很难达到处理的目的和要求。资源化转化为高附加值的VDF等产品,并且回收其中的溴元素工艺更具节能减排效益。 | 何兴娇 周俊 唐浩东 | 2014 | 有机氟工业2014，，2： | 0 |
