玻璃纤维膜电极表面水蒸发量的研究

Study of water evaporation on the surface of the electrode of glass fiber membrane

研究了高压电场下玻璃纤维膜电极表面的水蒸发量的变化规律.通过搭建实验台,测量了电场、电压、异极距、供水流量对玻璃纤维膜电极表面水蒸发量的影响.结果发现高压电场下的水蒸发量大于无电场工况的水蒸发量;随着电压提高,水蒸发量明显增加;随着异极距的减小,单位时间内的平均水蒸发量增加;随着供水流量的增加,单位时间内的平均水蒸发量略有增加.

The changes of water evaporation on the surface of the electrode of glass fiber membrane under high voltage electric fields were studied. The influences of electric field, electric voltage, heteropolar distance, water flow rate were investigated by building up a experimental platform. It was showed that water evaporated much more in high electric field than without it. With the increasing of electric voltage, the evaporation capacity of water increased obviously. And the average water evaporation in the unit time increased with the decrease of heterpolar distances. With the increasing of water flow, the average water evaporation in the unit time increased slightly.
