如图1-3所示，一种利用硅胶和高压电场的复合空气除湿干燥系统，包括硅胶除湿装置、高压电场除湿装置和抽风装置。在所述硅胶除湿装置上设有进风管1，并且所述硅胶除湿装置与所述高压电场除湿装置相互连通，所述抽风装置亦连通所述高压电场除湿装置以将外部空气经所述进风管1抽入并依次经过所述硅胶除湿装置和所述高压电场除湿装置。所述硅胶除湿装置内设有吸收空气中水分的硅胶涂层。所述高压电场除湿装置内形成将空气中的水分激发分离出的高压电场，在所述高压电场除湿装置内还设有吸收激发分离出的水分的氯化锂2。As shown in Figure 1-3, a composite air dehumidification and drying system using silica gel and high-voltage electric field, including silica gel dehumidification device, high-voltage electric field dehumidification device and exhaust device. An air inlet pipe 1 is provided on the silica gel dehumidification device, and the silica gel dehumidification device communicates with the high-voltage electric field dehumidification device. The air duct 1 draws in and passes through the silica gel dehumidification device and the high-voltage electric field dehumidification device in sequence. The silica gel dehumidification device is provided with a silica gel coating that absorbs moisture in the air. The high-voltage electric field dehumidification device forms a high-voltage electric field that excites and separates moisture in the air, and lithium chloride 2 that absorbs and excites the separated moisture is also provided in the high-voltage electric field dehumidification device.
所述硅胶除湿装置包括第一壳体3和塑料支柱4。所述第一壳体3的一侧设有所述进风管1。所述塑料支柱4设有多个，其均匀设置在所述第一壳体3的内部，每一个所述塑料支柱4的表面均涂有所述硅胶涂层。所述第一壳体3与所述进风管1相对的一侧通过第一风管5连通所述高压电场除湿装置。硅胶涂层即硅胶干燥剂是一种高活性吸附材料，通常是用硅酸钠和硫酸反应，并经老化、酸泡等一系列后处理过程而制得。硅胶属非晶态物质，其化学分子式为mSiO2.nH2O。不溶于水和任何溶剂，无毒无味，化学性质稳定，除强碱、氢氟酸外不与任何物质发生反应。硅胶的化学组份和物理结构，决定了它具有许多其它同类材料难以取代的特点。硅胶干燥剂吸附性能高、热稳定性好、化学性质稳定、有较高的机械强度等。空气先被硅胶除湿装置的硅胶涂层吸收水分一次除湿，每一个所述塑料支柱4的表面均涂有所述硅胶涂层，使得空气与硅胶涂层的接触面积大，有利于硅胶涂层吸收空气中的水分。The silica gel dehumidification device includes a first shell 3 and a plastic support 4 . One side of the first casing 3 is provided with the air inlet pipe 1 . There are multiple plastic pillars 4, which are evenly arranged inside the first housing 3, and the surface of each of the plastic pillars 4 is coated with the silicone coating. The side of the first housing 3 opposite to the air inlet pipe 1 communicates with the high voltage electric field dehumidification device through a first air pipe 5 . Silica gel coating, that is, silica gel desiccant, is a highly active adsorption material, which is usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. Silica gel is an amorphous substance, and its chemical formula is mSiO2.nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable in chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace. Silica gel desiccant has high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. The air is first dehumidified by the silica gel coating of the silica gel dehumidification device, and the surface of each of the plastic pillars 4 is coated with the silica gel coating, so that the contact area between the air and the silica gel coating is large, which is conducive to the absorption of the silica gel coating moisture in the air.
所述高压电场除湿装置包括高压发生器6、第二壳体7、电极板8和接地板9。所述第二壳体7的一侧通过所述第一风管5连通所述第一壳体3，其另一侧通过第二风管10连通所述抽风装置。所述氯化锂2处于所述第二壳体7内且对应所述第二风管10端口的位置处。所述电极板8和所述接地板9分别通过绝缘杆11上下相对固定在所述第二壳体7的内部，所述高压发生器6处于所述第二壳体7的外侧并通过导线连接所述电极板8，所述接地板9接地设置以与所述电极板8之间形成高压电场。在所述电极板8上均匀设有若干电极针12。当介质内部没有电荷源时，在两种介质的交界面上，电荷守恒性决定了电荷积蓄，其极性为：在电场作用下，两种层迭的欧姆流体界面上有电荷产生，如果在激发电极附近介质的电荷松弛时间大于远离电极处介质的电荷松弛时间，界面上的电荷与激发电极的极性相反，界面上的剪切力与行波方向相同，则向前驱动；如果激发电极附近的电荷松弛时间小于较远介质的电荷松弛时间，那么界面上的电荷与激发电极的极性相同，剪切力的方向与行波方向相反，形成向后驱动。通常情况下，物料可以假设为均匀电介质，介电常数受外界影响较小，电荷松弛时间主要由电导率决定，对于低电压或高频率情况，电极发射的电荷主要聚集在电极附近，从数量级上看，当电介质带电时，其电导率要比不带电时大，电导率梯度导致了松弛时间自电极向外递增，向后驱动。当在高电压或低频率时，在电极极性反向之前，电极发射的电荷跨越过中线，形成了与前面相反的情况，从而正向驱动.不管正向驱动还是反向驱动都会使物料中的水分子脱出或使氢键断开，达到脱水目的。通过高压电场除湿装置中的高压电场将空气中剩余的水分有效的激发分离出来，激发分离出来的水分被氯化锂吸收进行二次除湿，除湿效率高能保证排放空气的干燥度。The high-voltage electric field dehumidification device includes a high-voltage generator 6 , a second casing 7 , an electrode plate 8 and a ground plate 9 . One side of the second housing 7 communicates with the first housing 3 through the first air duct 5 , and the other side communicates with the air extractor through the second air duct 10 . The lithium chloride 2 is located in the second housing 7 and at a position corresponding to the port of the second air pipe 10 . The electrode plate 8 and the grounding plate 9 are relatively fixed up and down inside the second casing 7 through insulating rods 11, and the high voltage generator 6 is located outside the second casing 7 and connected by wires. The electrode plate 8 and the ground plate 9 are grounded to form a high voltage electric field with the electrode plate 8 . Several electrode needles 12 are uniformly arranged on the electrode plate 8 . When there is no charge source inside the medium, on the interface between the two media, the charge conservation determines the charge accumulation, and its polarity is: under the action of an electric field, there is charge generated on the interface of the two stacked ohmic fluids. The charge relaxation time of the medium near the excitation electrode is longer than the charge relaxation time of the medium away from the electrode, the charge on the interface is opposite to the polarity of the excitation electrode, and the shear force on the interface is in the same direction as the traveling wave, so it is driven forward; if the excitation electrode The nearby charge relaxation time is shorter than the charge relaxation time of the far medium, then the polarity of the charge on the interface is the same as that of the excitation electrode, and the direction of the shear force is opposite to the direction of the traveling wave, forming a backward drive. Normally, the material can be assumed to be a uniform dielectric, the dielectric constant is less affected by the outside world, and the charge relaxation time is mainly determined by the conductivity. For low voltage or high frequency conditions, the charges emitted by the electrodes are mainly gathered near the electrodes. From the order of magnitude See, when the dielectric is charged, its conductivity is greater than when it is not charged, and the conductivity gradient causes the relaxation time to increase outward from the electrode, driving backwards. When at high voltage or low frequency, before the polarity of the electrode is reversed, the charge emitted by the electrode crosses the neutral line, forming the opposite situation to the previous one, so that it is driven forward. No matter whether it is driven forward or reversed, it will make the material in the The water molecules come out or the hydrogen bonds are broken to achieve the purpose of dehydration. The high-voltage electric field in the high-voltage electric field dehumidification device effectively stimulates and separates the remaining moisture in the air, and the separated moisture is absorbed by lithium chloride for secondary dehumidification. The high dehumidification efficiency can ensure the dryness of the discharged air.
所述抽风装置包括第三壳体13、抽风机14和排风管15。所述第三壳体13的一侧通过所述第二风管10连通所述第二壳体7，其另一侧设有所述排风管15。在所述第三壳体13内设有将干燥的空气通过所述排风管15排出的所述抽风机14。所述第一壳体3、所述第二壳体7以及所述第三壳体13分别可开合的设有箱门，便于检修各个壳体的内部工况。The exhaust device includes a third housing 13 , an exhaust fan 14 and an exhaust pipe 15 . One side of the third casing 13 communicates with the second casing 7 through the second air pipe 10 , and the other side is provided with the exhaust pipe 15 . The exhaust fan 14 is provided in the third casing 13 to discharge dry air through the exhaust pipe 15 .
