【摘要】：針對現(xiàn)有除濕技術(shù)尚存在的缺陷,提出了一種基于電滲析的空氣直接除濕方法。該方法利用高壓靜電電離空氣,產(chǎn)生大量自由電子為水分子荷電,荷電水分子在靜電場作用下定向移動,再利用高分子纖維膜對水分子的選擇透過作用將水分子與其他易荷電的負(fù)電性分子分離,從而實(shí)現(xiàn)除濕的目的。根據(jù)該原理構(gòu)建了驗(yàn)證性實(shí)驗(yàn)裝置,對該方法進(jìn)行了實(shí)驗(yàn)驗(yàn)證,結(jié)果表明,在電場作用下高分子纖維膜兩側(cè)含濕量產(chǎn)生變化,證明了水分子在電場力作用下從膜的一側(cè)轉(zhuǎn)移到了另一側(cè),實(shí)現(xiàn)了負(fù)電暈線側(cè)的除濕。該方法有望發(fā)展成為一種無相變,無需再生的新型除濕技術(shù)。
[Abstract]:A direct air dehumidification method based on electrodialysis is proposed to overcome the shortcomings of the existing dehumidification technology. This method uses high voltage electrostatic ionization air to produce a large number of free electrons to be charged by water molecules. The charged water molecules move in the direction under the electrostatic field, and then separate the water molecules from other electrically charged negative molecules through the selection of water molecules by the polymer fiber membrane. According to the principle, a confirmatory experimental device was constructed, and the method was verified experimentally. The results show that the moisture content on both sides of the polymer fiber membrane changes under the electric field. It is proved that the water molecule is transferred from one side of the membrane to the other side under the action of electric field force, and the dehumidification of the negative corona line side is realized. This method is expected to develop into a new dehumidification technology without phase transition and no regeneration.
