When the air dehumidifying device is in actual use, air enters the air dehumidifying device and contacts with the adsorbent, and the adsorbent absorbs moisture in the air to reduce the air humidity. Specifically, an adsorption net frame is generally arranged in the dehumidifying device, an adsorbent is loaded on the adsorption net frame, and the air flow direction is perpendicular to the adsorption net frame. When the adsorbent reaches the upper adsorption limit, the adsorbent needs to be regenerated, and the regeneration of the adsorbent refers to the process of separating or decomposing the moisture adsorbed on the surface of the adsorbent by a physical or chemical method on the premise of not damaging the original structure of the adsorbent, recovering the adsorption performance of the adsorbent and enabling the adsorbent to be reused. Common regeneration methods include thermal regeneration, ultrasonic regeneration, electrochemical regeneration, biological regeneration, and wet oxidation regeneration.
However, the manner in which the air flow direction is perpendicular to the adsorption frame causes air to rapidly flow through the adsorption frame, and the contact time with the adsorbent is too short, so that the adsorption rate is lowered, and the final dehumidification effect is affected. In addition, the adsorbent generally has the defect of difficult regeneration, and for a closed container, moisture in the regenerated air is easily absorbed by the adsorbent again, so that the problem of low regeneration efficiency is caused.

At present, the common dehumidifying device in the market absorbs moisture in the air through the adsorbent, so that the effect of reducing the air humidity is achieved. In general, in order to raise the contact area of the adsorbent with air as much as possible, the adsorbent is crushed into particles and packed in a porous gauze bag or frame structure, and the air is allowed to contact the adsorbent after entering the dehumidifying apparatus. When the adsorption amount of the adsorbent reaches the upper limit, the moisture in the adsorbent is dispersed into the atmosphere in a physical or chemical mode, so that the adsorption capacity of the adsorbent is recovered, and the next dehumidification operation is continued.
However, since a fan is generally provided in the dehumidifying apparatus to accelerate the inflow and outflow of air, the air flow rate is relatively high and the contact time with the adsorbent is too short, thereby causing insufficient absorption of moisture in the air. In this regard, the existing dehumidifying device also has the function of layered adsorption by arranging multiple layers of adsorbents, but the production cost and the volume of the dehumidifying device can be certainly improved, and the utilization rate of the adsorbents is not high. Secondly, the adsorbent is regenerated in a chemical mode, so that chemical substances harmful to the environment are easy to generate, a special recovery system is required to be arranged, and the device is inconvenient to use; the physical mode is adopted to regenerate the adsorbent, so that the energy consumption is higher, and if the water vapor is not condensed and recovered in time, the water vapor can be absorbed by the adsorbent again after the regeneration work is finished, so that the regeneration is not thorough.
Therefore, in the embodiment of the present utility model, the first thermoelectric semiconductor 320 and the second thermoelectric semiconductor 330 are respectively disposed at two sides of the dehumidifying mesh frame 310 and are not symmetrically disposed, so that after air is introduced into the dehumidifying mesh frame 310, the air is forced to move along the length direction of the dehumidifying mesh frame 310, thereby increasing the resistance in the air flowing process to reduce the flow velocity, prolonging the contact time of the air and the adsorbent, and improving the service efficiency of the adsorbent. In addition, due to the characteristic that one side of the thermoelectric semiconductor generates heat and the other side generates refrigeration, during regeneration, the heat generating sides of the first thermoelectric semiconductor 320 and the second thermoelectric semiconductor 330 are attached to the dehumidifying screen frame 310 and generate heat, and moisture in the adsorbent is evaporated into water vapor; meanwhile, the refrigerating sides of the first thermoelectric semiconductor 320 and the second thermoelectric semiconductor 330 face outwards and refrigerate the inside of the dehumidifying device, so that condensation of moisture in air is accelerated, condensed water can be timely recovered, moisture in air is prevented from being absorbed by the adsorbent again after regeneration is finished, and regeneration efficiency is improved.

The case 100 is provided with an air inlet 110 and an air outlet 120, and moist air enters from the air inlet 110 and, after dehumidification, dry air flows out from the air outlet 120. To facilitate the entry and exit of air, at least one of the air inlet 110 and the air outlet 120 is provided with a fan 200, and one fan 200 may be installed in the air inlet 110 or the air outlet 120, or one fan 200 may be installed in each of the air inlet 110 and the air outlet 120.
The dehumidifying assembly 300 is for dehumidifying air, and includes a dehumidifying mesh frame 310, a first thermoelectric semiconductor 320, and a second thermoelectric semiconductor 330. The dehumidifying screen frame 310 is installed in the box body 100, is in a frame-shaped structure and is provided with an adsorbent, the adsorbent is specifically activated alumina particles, the regeneration rate of the material can reach 89.34% at 120 ℃, the regeneration time is only 100min, the effective regeneration amount reaches 1.53g/kg min, and compared with other regeneration materials, the regeneration time is shorter; the regeneration amount W of the material has a mathematical relation with the temperature T that W=21.2877lnT+113.74, and the higher the temperature is, the higher the regeneration rate is; the moisture absorption amount of the material is 17.24g/kg per hour, and the material has good moisture absorption effect. Furthermore, the dehumidifying screen 310 is embodied as a copper screen, so that heat can be transferred more quickly during regeneration, and the regeneration process of the adsorbent can be accelerated.

The refrigerating sides of the first thermoelectric semiconductor 320 and the second thermoelectric semiconductor 330 are disposed outward, so that the heated and evaporated water vapor can be rapidly condensed into liquid water after contacting the refrigerating side, and the water vapor is prevented from being absorbed again by the adsorbent after the regeneration is completed. It is readily understood that the temperature of the heat generating side is higher than the temperature of the cooling side in the thermoelectric semiconductor.

At the bottom of the septum 500 is provided a collection box 600 provided with a pit to store liquid water flowing down from the septum 500. The collecting box 600 can be separated from the case 100, thereby facilitating the user to empty the water in the collecting box 600.

Wherein, the air passes through the air inlet 110, the first opening 3111, the dehumidifying frame 310, the second opening 3121 and the air outlet 120 in order and flows out of the outside.
