针对现有除湿技术尚存在的缺陷,提出了一种基于电渗析的空气直接除湿方法。该方法利用高压静电电离空气,产生大量自由电子为水分子荷电,荷电水分子在静电场作用下定向移动,再利用高分子纤维膜对水分子的选择透过作用将水分子与其他易荷电的负电性分子分离,从而实现除湿的目的。根据该原理构建了验证性实验装置,对该方法进行了实验验证,结果表明,在电场作用下高分子纤维膜两侧含湿量产生变化,证明了水分子在电场力作用下从膜的一侧转移到了另一侧,实现了负电晕线侧的除湿。该方法有望发展成为一种无相变,无需再生的新型除湿技术。
Aiming at the existing defects of the existing dehumidification technology, a direct air dehumidification method based on electrodialysis was proposed. The method utilizes high-pressure electrostatic ionization air to generate a large amount of free electrons to be charged by water molecules. The charged water molecules move directionally under the action of an electrostatic field, and then the polymer fiber membrane is used to selectively permeate water molecules to make water molecules easier to use. The negatively charged molecules of the charge are separated to achieve dehumidification. Based on this principle, a confirmatory experimental device was constructed and verified by experiments. The results show that under the action of an electric field, the moisture content on both sides of the polymer fiber membrane changes, which proves that the water molecules are under the action of the electric field force. The side was transferred to the other side and dehumidification on the negative corona wire side was achieved. This method is expected to develop into a new dehumidification technology without phase change and without regeneration.
