And one side of the first shell 3 opposite to the air inlet pipe 1 is communicated with the high-voltage electric field dehumidification device through a first air pipe 5. Silica gel coating, i.e. silica gel desiccant, is a highly active adsorbent material, usually prepared by reacting sodium silicate with sulfuric acid, and subjecting to a series of post-treatment processes such as aging and acid soaking. Silica gel is an amorphous substance and has a chemical molecular formula of mSiO2.nH 2O. Insoluble in water and any solvent, non-toxic, odorless, stable in chemical property, and non-reactive with any substance except strong alkali and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has the characteristic of difficult substitution of many other similar materials.

The air is once dehumidified by silica gel dehydrating unit's silica gel coating absorption moisture earlier, each the surface of plastics pillar 4 all scribbles the silica gel coating for the area of contact of air and silica gel coating is big, is favorable to the silica gel coating to absorb the moisture in the air.
The high-voltage electric field dehumidification device comprises a high-voltage generator 6, a second shell 7, an electrode plate 8 and a grounding plate 9. One side of the second shell 7 is communicated with the first shell 3 through the first air pipe 5, and the other side of the second shell is communicated with the air draft device through the second air pipe 10. The lithium chloride 2 is positioned in the second shell 7 and corresponds to the position of the port of the second air duct 10.

When there is no charge source inside the media, charge conservation determines charge accumulation at the interface between the two media, with the polarities: under the action of an electric field, charges are generated on the interface of the two laminated ohmic fluids, and if the charge relaxation time of a medium near the excitation electrode is longer than that of a medium far away from the excitation electrode, the charges on the interface are opposite to the polarity of the excitation electrode, and the shearing force on the interface is the same as the traveling wave direction, the forward driving is carried out; if the charge relaxation time near the excitation electrode is less than that of the more distant medium, then the charge at the interface is the same polarity as the excitation electrode and the shear force is directed in the opposite direction to the traveling wave, resulting in a back drive. In general, the material can be assumed to be a uniform dielectric medium, the dielectric constant is less influenced by the outside, the charge relaxation time is mainly determined by the conductivity, in the case of low voltage or high frequency, the charge emitted by the electrode is mainly accumulated near the electrode, and in terms of magnitude, when the dielectric medium is charged, the conductivity is larger than that when the dielectric medium is not charged, and the conductivity gradient causes the relaxation time to increase outwards from the electrode and drive backwards. When the voltage is high or the frequency is low, before the polarity of the electrode is reversed, the electric charge emitted by the electrode crosses the neutral line, the opposite condition is formed, so that the forward driving can remove water molecules in the material or break hydrogen bonds, and the dehydration purpose is achieved.
