| 摘 要： | 研究气液两相介质阻挡放电(DBD)的特性,对于深入理解其放电机理、促进其在环保等工业领域中应用具有重要意义。通过电压电流波形和Lissajous图形等电气特性诊断及发射光谱和发光图像等光学特性诊断,研究了液体成分对大气压气液两相DBD放电特性的影响。比较了苯胺和苯胺加NaOH溶液中气液两相DBD放电特性,利用实验结果计算得到放电功率和传输电荷,并结合放电理论对放电机制进行了分析。结果表明,苯胺加NaOH溶液中气液两相DBD,其放电特性与纯苯胺溶液有明显不同,相同电压下其放电电流约为纯苯胺溶液的两倍,其发光强度更强,放电功率和传输电荷更大,且在光谱特性图波长589nm处出现Na原子谱线,NaOH的加入增加了溶液的电导率,同时促进了气相放电强度,使得放电增强。

| Abstract: | It is of great significance to study the characteristic of gas-liquid two-phase dielectric barrier discharge (DBD) and understand its discharge mechanism deeply for further environmental and other industrial applications. In this paper, by diagnosing voltage-current waveforms, Lissajous graphics and other electrical characteristics and optical characteristics such as emission spectra and luminescence images, the effects of different liquid components to the discharge characteristics of gas-liquid two-phase DBD at atmosphere pressure were studied. The discharge characteristics of gas-liquid two-phase DBD in aniline and aniline with NaOH solutions were compared , the experimental results were used to calculate discharge power and transmission charge, the discharge mechanism was analyzed based on discharge theory. The results show that for gas-liquid two-phase DBD in aniline solution with NaOH, the discharge characteristic was significantly different from that of pure aniline, the discharge current is about twice that of pure aniline solution at the same voltage, the luminous intensity is stronger, the discharge power and the transmission charge are larger, and at 589 nm wavelength of the spectral characteristic graph Na atomic line appears, the conductivity of the solution was increased when NaOH was added, hence gas phase discharge intensity was enhanced and the discharge became stronger. |
