摘要

润湿性对过滤器的凝聚性能有重要影响。本文以商用玻璃纤维过滤器为基材，通过浸涂和电喷雾制备了 Janus 过滤器。Janus 过滤器的压降显著降低，湿压降仅为 2.8 kPa，而原过滤器为 6.1 kPa，亲油过滤器为 5.4 kPa。值得注意的是，涂层深度对提高 Janus 过滤器的凝聚性能起着至关重要的作用。此外，将獐牙菜过滤器反向放置时，其品质因数增加了 2.87 倍，这表明方向是獐牙菜过滤器聚结性能的关键因素。研究结果表明，在聚结过滤中应用 Janus 过滤器具有巨大的潜力。

Coalescence performance of Janus filter for the removal of oil mist

The wettability has an important effect on coalescence performance of filter. In this paper, we utilized a commercial glass fiber filter as the substrate to prepared the Janus filter through dip-coating and electrospraying. The Janus filter exhibited a remarkable reduction in pressure drop, with only 2.8 kPa of wet pressure drop compared to 6.1 kPa for the original filter and 5.4 kPa for the oleophilic filter. Notably, the coating depth played a critical role in enhancing the coalescence performance of the Janus filter. Furthermore, when placing the Janus filter in reverse direction, its quality factor increased by 2.87 times, highlighting that orientation is an essential factor for coalescence performance of Janus filters. The results indicate great potential in the application of Janus filters for coalescence filtration.

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
