Abstract In this work, we explore the effect of electric field distribution and incorporating two different frequencies in two different regions of a trigrid coalescer on the electrocoalescer efficiency. Specifically grounding water at the bottom of the coalescer is found to be effective. The effect of frequency on emulsion breakup is essentially due to chaining tendency of water droplets at high frequencies. The reason for this could be reduced electrostatic force between drops at higher frequencies due to higher capacitance of interstitial oil film between two droplets. Moreover, at low frequencies significant bouncing of drops from interface is observed, leading to lower separation rates.

静电边界条件和频率对三格静电聚结器性能影响的实验研究

摘要 在这项工作中，我们探讨了电场分布和在三栅聚结器的两个不同区域中结合两种不同频率对电聚结器效率的影响。发现特别是在聚结器底部的地下水是有效的。频率对破乳的影响主要是由于水滴在高频下的链状趋势。其原因可能是由于两个液滴之间的间隙油膜的电容较高，因此在较高频率下液滴之间的静电力会降低。此外，在低频下观察到液滴从界面显着反弹，导致较低的分离率。
