Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning technology, and in particular to a dehumidification device. Background Technology
[0002] Manufacturing plants typically use modular air conditioning units (MAUs) for temperature and humidity control. To improve the accuracy of this control, it's necessary to replenish the MAUs with fresh outdoor air. However, the humidity of this fresh outdoor air fluctuates significantly under different climatic conditions. To reduce the energy consumption of these MAUs, separate dehumidification of the fresh outdoor air is currently recommended. Generally, low-temperature chilled water condensation can be used for dehumidification; however, this method requires the production of chilled water, resulting in high energy consumption. Alternatively, desiccant can be used to absorb water vapor. Once sufficient water vapor has been absorbed, the desiccant's absorption capacity gradually decreases, necessitating heating to desorb the water vapor and restore its normal dehumidification capacity. However, heating the desiccant leaves some heat residue, raising the air temperature during subsequent dehumidification. Therefore, cooling of the fresh outdoor air is necessary before or after dehumidification. Thus, both heating the desiccant and cooling the fresh outdoor air consume substantial amounts of energy, increasing overall energy consumption. Utility Model Content
[0003] One of the technical problems addressed by this application is how to reduce the energy consumption of dehumidification devices.
[0004] A dehumidification device, comprising:
[0005] A rotating mechanism includes a rotating wheel and an adsorption element, the adsorption element being disposed on the rotating wheel, and the rotating mechanism having a dehumidification area, a regeneration area, and a heat dissipation area arranged along the rotation direction of the rotating wheel, the adsorption element rotating with the rotating wheel between the dehumidification area, the regeneration area, and the heat dissipation area;
[0006] A dehumidification mechanism having a dehumidification channel extending to the dehumidification area, wherein humid air in the dehumidification channel enters the adsorption element through the dehumidification area; and
[0007] A regeneration mechanism having a regeneration channel extending to the regeneration area, wherein hot air in the regeneration channel enters the adsorption element through the regeneration area;
[0008] The adsorption element dissipates heat in the heat dissipation area via the rotating wheel.
[0009] In one embodiment, the dehumidification area has the largest coverage area on the rotor, the heat dissipation area has the second largest coverage area on the rotor, and the regeneration area has the smallest coverage area on the rotor.
[0010] In one embodiment, the rotating wheel is circular and divided into eight sector blocks with equal central angles. Each sector block is provided with the adsorption element. The dehumidification area, the regeneration area, and the heat dissipation area cover different sector blocks. The dehumidification area covers four adjacent sector blocks, the regeneration area covers one sector block, and the heat dissipation area covers three sector blocks.
[0011] In one embodiment, the rotating wheel includes a rotating shaft, multiple radial supports, and multiple heat dissipation rings. Each radial support is connected to the rotating shaft and extends a predetermined length radially along the rotating wheel. The multiple radial supports are spaced apart along the rotation direction of the rotating wheel. The heat dissipation rings are disposed on the radial supports and are spaced apart radially along the rotating wheel. Multiple installation spaces are formed between the heat dissipation rings and the radial supports, and the adsorption member is disposed within the installation space.
[0012] In one embodiment, along the radial direction of the rotating wheel, the orthographic projection of the adsorption member onto the heat dissipation ring is smaller than the coverage area of the heat dissipation ring, and the entire orthographic projection lies within the coverage area of the heat dissipation ring.
[0013] In one embodiment, the heat dissipation ring has a mounting portion and two heat dissipation portions, the mounting portion being connected between the two heat dissipation portions, the mounting portion and the two heat dissipation portions being arranged along the extension direction of the axis around which the rotating wheel rotates, and the adsorption member being disposed on the mounting portion.
[0014] In one embodiment, at least one of the following schemes is also included:
[0015] The two heat dissipation sections have equal lengths in the direction of extension of the axis around which the rotating wheel rotates;
[0016] The surface of the mounting part that contacts the adsorption element is a rough surface.
[0017] In one embodiment, the heat dissipation ring has a through hole, or the rotating wheel further includes heat dissipation fins disposed on the heat dissipation ring.
[0018] In one embodiment, the heat dissipation ring has an inner cavity for receiving phase change material, in which the phase change material changes at least partially from a liquid to a gaseous state in the dehumidification region.
[0019] In one embodiment, the rotating mechanism further includes a motor that drives the wheel to rotate intermittently.
[0020] One technical advantage of one embodiment of this application is that when the adsorbent rotates from the regeneration area to the heat dissipation area, heat exchange occurs with the outside environment through the thermal conduction of the rotating wheel. This allows the heat on the adsorbent to be directly conducted to the outside environment through the rotating wheel, restoring it to room temperature. This effectively prevents the heat on the adsorbent from being conducted to the humid air, thus avoiding an increase in the temperature of the fresh air output from the dehumidification unit. Therefore, the dehumidification device can fully utilize the thermal conduction of the rotating wheel to dissipate heat from the adsorbent in the heat dissipation area, eliminating the need for additional refrigeration equipment to cool the adsorbent, thereby reducing the energy consumption of the dehumidification device.

[0032] See Figure 1 , Figure 2 and Figure 3 An embodiment of this application provides a dehumidification device 10, including a rotating mechanism 100, a dehumidification mechanism 200, and a regeneration mechanism 300. The rotating mechanism 100 includes a rotating wheel 110 and an adsorption element 120, with the adsorption element 120 disposed on the rotating wheel 110. The rotating mechanism 100 has a dehumidification area 101, a regeneration area 102, and a heat dissipation area 103, which are arranged along the rotation direction. When the rotating wheel 110 rotates, the adsorption element 120 follows the rotating wheel 110 and rotates between the dehumidification area 101, the regeneration area 102, and the heat dissipation area 103. For example, for the same adsorption element 120, when it is initially located in the dehumidification area 101, during rotation, the adsorption element 120 then moves to the regeneration area 102, then moves from the regeneration area 102 to the heat dissipation area 103, and then returns from the heat dissipation area 103 to the dehumidification area 101, thus completing the first movement cycle of the adsorption element 120. When the rotor 110 rotates again, the adsorbent 120 will pass through the regeneration zone 102 and the heat dissipation zone 103 in sequence before returning to the dehumidification zone 101, thus completing the second cycle of the adsorbent 120. Therefore, as the rotor 110 continues to rotate, the same adsorbent 120 will repeatedly cycle between the dehumidification zone 101, the regeneration zone 102, and the heat dissipation zone 103.
[0033] See Figure 1 , Figure 2 and Figure 3 The dehumidification mechanism 200 has a dehumidification channel 201 that extends to the dehumidification area 101. The adsorption element 120 has micropores, thus possessing a certain porosity. The adsorption element 120 can absorb water vapor while allowing gas to pass through. The dehumidification channel 201 first draws in humid air from the outside. When the humid air arrives at the dehumidification area 101, it enters the adsorption element 120 covered by the dehumidification area 101, causing the adsorption element 120 to absorb moisture from the humid air. As the humid air passes through the adsorption element 120, its humidity decreases, transforming the humid air passing through the adsorption element 120 into fresh air with a humidity level meeting the set requirements.
[0034] See Figure 1 , Figure 2 and Figure 3 The regeneration mechanism 300 has a regeneration channel 301 that extends to the regeneration zone 102. This channel utilizes waste heat resources from the factory for heat exchange, thereby reducing energy consumption for both the dehumidifier 10 and the factory. Furthermore, the gas in the regeneration channel 301 absorbs this waste heat and is converted into hot air, which is then introduced into the regeneration zone 102. When the hot air enters the regeneration zone 102, it then enters the adsorption element 120 covered by the regeneration zone 102. Therefore, after the adsorbent 120 covered by dehumidification absorbs moisture from the humid air, as the rotor 110 rotates, the adsorbent 120 that has absorbed moisture will rotate from the dehumidification zone 101 to the regeneration zone 102. At this time, hot air enters the adsorbent 120 to evaporate the moisture inside the adsorbent 120, thereby evaporating the moisture inside the adsorbent 120 and dehydrating the adsorbent 120. This allows the adsorbent 120 to regain its adsorption function for water vapor in the gas, which can be understood as achieving the "regeneration" of the adsorbent 120.
[0035] See Figure 2 , Figure 3 and Figure 4 When the adsorbent 120 covered by the regeneration zone 102 is regenerated due to dehydration in the regeneration zone 102, as the rotor 110 rotates, the regenerated adsorbent 120 will rotate from the regeneration zone 102 to the heat dissipation zone 103. At this time, the heat absorbed by the adsorbent 120 from the hot air in the regeneration zone 102 will be directly discharged to the outside through the rotor 110, thus restoring the adsorbent 120 to room temperature. When the adsorbent 120, which has returned to room temperature, rotates from the heat dissipation zone 103 to the dehumidification zone 101, it can effectively prevent the heat on the high-temperature adsorbent 120 from being conducted to the humid air in the dehumidification zone 101, ensuring that the temperature of the fresh air output from the dehumidification mechanism 200 meets the set requirements.
[0036] If the regenerated adsorbent 120 is cooled by a refrigeration device to return it to room temperature, thus preventing heat from the regenerated adsorbent 120 from being conducted to the humid air and raising the temperature of the fresh air output from the dehumidification unit 200, the refrigeration device would consume additional energy, thereby increasing the energy consumption of the dehumidification device 10.
[0037] See Figure 2 , Figure 3 and Figure 4Regarding the dehumidification device 10 in the above embodiment, when the regenerated adsorbent 120 rotates from the regeneration zone 102 to the heat dissipation zone 103, it exchanges heat with the outside through the heat conduction of the rotating wheel 110. This allows the heat on the adsorbent 120 to be directly conducted to the outside through the rotating wheel 110 to restore it to normal temperature, effectively preventing the heat on the regenerated adsorbent 120 from being conducted to the humid air and affecting the temperature of the fresh air output from the dehumidification mechanism 200. Therefore, the dehumidification device 10 can fully utilize the heat conduction of the rotating wheel 110 to dissipate heat from the regenerated adsorbent 120 in the heat dissipation zone 103, without the need for additional refrigeration equipment to dissipate heat from the regenerated adsorbent 120, thus reducing the energy consumption of the dehumidification device 10. It can be understood that the heat in the regenerated medium-heat air comes from the waste heat resources of the factory, so by fully utilizing the waste heat resources of the factory, the energy consumption of the dehumidification device 10 can also be effectively reduced.
[0038] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the rotor 110 rotates intermittently, which can be understood as similar to the pulse rotation of a clock. Therefore, when the adsorbent 120 rotates in the dehumidification zone 101, the adsorbent 120 will remain in the dehumidification zone 101 for a certain period of time, allowing sufficient time for the humid air in the dehumidification channel 201 to contact the adsorbent 120. This ensures that the adsorbent 120 absorbs the moisture from the humid air in the dehumidification zone 101, ultimately ensuring that the fresh air output from the dehumidification mechanism 200 meets the set humidity requirements. Similarly, when the adsorbent 120, after absorbing moisture, rotates from the dehumidification zone 101 to the regeneration zone 102, the adsorbent 120 will remain in the regeneration zone 102 for a certain period of time, allowing sufficient heat exchange between the adsorbent 120 and the hot air in the regeneration zone 102, thereby removing the moisture from the adsorbent 120 and achieving regeneration. When the regenerated adsorbent 120 rotates from the regeneration area 102 to the heat dissipation area 103, the regenerated adsorbent 120 will also stay in the heat dissipation area 103 for a certain period of time, so that the regenerated adsorbent 120 has enough time to dissipate heat through the heat conduction of the rotating wheel 110, so that the adsorbent 120 returns to room temperature, and finally ensures that the adsorbent 120 after returning to room temperature rotates back to the dehumidification area 101 to absorb moisture in the humid air, and the adsorbent 120 after returning to room temperature will not raise the temperature of the humid air additionally.
[0039] See Figure 2 , Figure 3 and Figure 4It can be understood that, at the same time, the adsorbent 120 covered by the dehumidification zone 101 can dehumidify the humid air from the dehumidification channel 201, while the adsorbent 120 covered by the regeneration zone 102 can be regenerated by evaporating moisture from the hot air from the regeneration channel 301. The adsorbent 120 covered by the heat dissipation zone 103 can release heat through the rotor 110 to return to normal temperature. Therefore, the adsorbents 120 covered by the dehumidification zone 101, regeneration zone 102, and heat dissipation zone 103 can each perform different functions at the same time. This eliminates intermediate waiting time, thereby improving the working efficiency of the dehumidification device 10.
[0040] In other implementations, the rotor 110 can also rotate continuously at a certain speed, as long as the adsorption element 120 passes through the dehumidification zone 101, regeneration zone 102, and heat dissipation zone 103 respectively within a set time period. It can be understood that the adsorption element 120 needs to consume a certain amount of time to pass through the dehumidification zone 101, regeneration zone 102, and heat dissipation zone 103 respectively; as long as the time consumed meets the set requirements, it is acceptable.
[0041] See Figure 2 , Figure 3 and Figure 4In some embodiments, the rotating mechanism 100 further includes a motor 130. The rotating wheel 110 includes a rotating shaft 111, radial supports 112, and a heat dissipation ring 113. The rotating wheel 110 can be circular. The rotating shaft 111 is located at the center of the rotating wheel 110. The motor 130 can drive the rotating shaft 111 to rotate via a gear transmission mechanism, causing the rotating wheel 110 to rotate intermittently around the axis of the rotating shaft 111. There are multiple radial supports 112, spaced apart along the rotation direction of the rotating wheel 110, and extending radially along the rotating wheel 110. One end of each radial support 112 is fixedly connected to the rotating shaft 111, and one end of each radial support 112 is spaced a certain distance from the rotating shaft 111 along the radial direction of the rotating wheel 110. The heat dissipation ring 113 can be annular and is disposed on the radial support member 112. Multiple heat dissipation rings 113 are arranged radially spaced along the rotating wheel 110, and each heat dissipation ring 113 can be fixedly connected to all radial support members 112. Therefore, through the connection between the radial support member 112 and the heat dissipation ring 113, the rotating wheel 110 has a mesh structure with multiple openings. These openings can be understood as the installation spaces enclosed between the heat dissipation rings 113 and the radial support members 112. Obviously, there are multiple installation spaces. The adsorption member 120 is disposed within this installation space. The number of adsorption members 120 is equal to the number of installation spaces, forming a one-to-one correspondence. That is, each installation space contains an adsorption member 120. Therefore, the adsorption member 120 can fully utilize the installation space, avoiding the adsorption member 120 occupying space outside the installation space, thereby achieving a compact and miniaturized design of the rotating mechanism 100.
[0042] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the dehumidification zone 101 has the largest coverage area on the rotor 110, the heat dissipation zone 103 has the second largest coverage area on the rotor 110, and the regeneration zone 102 has the smallest coverage area on the rotor 110. This can be understood as the dehumidification zone 101 covering the largest number of adsorption elements 120, meaning the dehumidification zone 101 corresponds to the largest number of adsorption elements 120; the heat dissipation zone 103 covering the second largest number of adsorption elements 120, meaning the heat dissipation zone 103 corresponds to the second largest number of adsorption elements 120; and the regeneration zone 102 covering the smallest number of adsorption elements 120, meaning the regeneration zone 102 corresponds to the smallest number of adsorption elements 120. Therefore, by considering the area of the rotating wheel 110 covered by the dehumidification zone 101, the regeneration zone 102, and the heat dissipation zone 103, and the number of adsorption elements 120, the adsorption elements 120 can have sufficient and reasonable time for dehumidification, regeneration, and heat dissipation in different zones, avoiding excessively long or short residence times for the adsorption elements 120 in different zones, thereby reasonably providing the rotational speed of the rotating wheel 110 and ultimately improving the working efficiency of the dehumidification mechanism 200.
[0043] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the rotor 110 is divided into eight sector-shaped blocks with equal central angles, and each sector-shaped block has an adsorption element 120 disposed in different installation spaces. The dehumidification zone 101, regeneration zone 102, and heat dissipation zone 103 each cover different sector-shaped blocks. The dehumidification zone 101 covers four adjacent sector-shaped blocks, located at positions A1, A2, A3, and A4 respectively. The regeneration zone 102 covers one sector-shaped block, located at position B1. The heat dissipation zone 103 covers three sector-shaped blocks, located at positions C1, C2, and C3 respectively. This arrangement results in the highest area of the rotor 110 and the lowest number of adsorption elements 120 covered by the dehumidification zone 101, followed by the heat dissipation zone 103, and the lowest area of the rotor 110 and the lowest number of adsorption elements 120 covered by the regeneration zone 102. For example, the number of radial support members 112 can be exactly eight, and a sector block is formed between any two adjacent radial support members 112, so that the rotating wheel 110 is divided into eight sector blocks with equal central angles.
[0044] See Figure 2 , Figure 3 and Figure 4 In some embodiments, along the radial direction of the rotating wheel 110, the orthographic projection of the adsorption member 120 on the heat dissipation ring 113 is smaller than the coverage area of the heat dissipation ring 113, and the entire orthographic projection lies within the coverage area of the heat dissipation ring 113. This can be understood as the adsorption member 120 entirely resting on the heat dissipation ring 113. On the one hand, this allows the heat dissipation ring 113 to provide sufficient mounting surface for the adsorption member 120, thereby improving the connection strength between the adsorption member 120 and the heat dissipation ring 113. On the other hand, the portion of the heat dissipation ring 113 not covered by the adsorption member 120 can effectively dissipate heat from the adsorption member 120, thereby improving the heat dissipation efficiency of the adsorption member 120 within the heat dissipation area 103.
[0045] See Figure 2 , Figure 3 and Figure 4In some embodiments, the heat dissipation ring 113 has a mounting portion 1131 and a heat dissipation portion 1132. There is one mounting portion 1131 and two heat dissipation portions 1132. The mounting portion 1131 and the two heat dissipation portions 1132 are arranged along the extension direction of the axis around which the rotating wheel 110 rotates, that is, the mounting portion 1131 and the two heat dissipation portions 1132 are arranged along the axial direction of the rotating shaft 111. The adsorption member 120 is disposed on the mounting portion 1131, so the adsorption member 120 covers the mounting portion 1131. The adsorption member 120 is not disposed on the heat dissipation portion 1132, so the adsorption member 120 does not cover the heat dissipation portion 1132. This allows the two heat dissipation portions 1132 on the heat dissipation ring 113 to reasonably increase the heat dissipation area, thereby providing a good heat dissipation effect for the adsorption member 120 within the heat dissipation area 103.
[0046] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the two heat dissipation parts 1132 have equal lengths in the direction of extension of the axis around which the rotating wheel 110 rotates. This can be understood as the two heat dissipation parts 1132 being symmetrically arranged relative to the mounting part 1131, or as the distances from the two ends of the adsorption member 120 to the heat dissipation ring 113 in the axial direction of the rotating shaft 111 being equal, i.e., the adsorption member 120 being centrally located on the heat dissipation ring 113. This can improve the heat dissipation effect of the adsorption member 120 in the heat dissipation area 103 while ensuring the connection strength between the adsorption member 120 and the heat dissipation ring 113. The surface of the mounting part 1131 that contacts the adsorption member 120 is a rough surface, i.e., the surface of the mounting part 1131 that contacts the adsorption member 120 has a high roughness, which can improve the adhesion between the adsorption member 120 and the mounting part 1131, thereby improving the connection strength between the adsorption member 120 and the heat dissipation ring 113.
[0047] In some embodiments, for example, a through hole is provided on the heat dissipation ring 113, or the rotor 110 further includes heat dissipation fins disposed on the heat dissipation ring 113. Therefore, the heat conduction of the rotor 110 can be further improved through the through hole or heat dissipation fins, thereby improving the heat dissipation effect of the rotor 110 on the adsorption member 120 located in the heat dissipation area 103. Alternatively, the heat dissipation ring 113 may have a hollow structure, i.e., the heat dissipation ring 113 has an inner cavity in which a phase change material can be embedded. In the dehumidification area 101, humid air condenses from a gaseous state to a liquid state, releasing heat. The phase change material absorbs at least part of the heat released by the humid air and changes from a liquid state to a gaseous state. This increases the heat storage capacity of the dehumidification area 101, reduces the temperature rise of the dehumidified air, and improves the dehumidification efficiency.
[0048] In some embodiments, the rotating mechanism 100 further includes a sealing element disposed in the heat dissipation area 103 to seal the adsorbent 120 covered by the heat dissipation area 103. This reduces the amount of water vapor from the outside air entering the adsorbent 120 in the heat dissipation area 103, thus reducing the impact of moisture adsorption by the adsorbent 120 in the heat dissipation area 103 on the subsequent moisture absorption effect in the dehumidification area 101. In other embodiments, dry, cold air can be introduced into the heat dissipation area 103, allowing the dry, cold air to absorb the heat from the adsorbent 120 in the heat dissipation area 103, causing the adsorbent 120 to quickly dissipate heat and return to room temperature. Of course, the dry, cold air may absorb heat or be converted into dry, high-temperature air, which can be introduced into the regeneration channel 301 to evaporate moisture from the adsorbent 120 in the regeneration area 102, thereby achieving recycling.
[0049] See Figure 1 In some embodiments, the dehumidification mechanism 200 includes a fresh air duct 210, a fresh air filter 220, a fresh air fan 230, and an air conditioning unit 240. When the fresh air fan 230 is working, the fresh air duct 210 draws in humid air from the outside. The humid air is filtered by the fresh air filter 220. The filtered humid air is dehumidified by the adsorption element 120 covered by the dehumidification area 101. The fresh air formed after dehumidification will enter the air conditioning unit 240.
[0050] See Figure 1 In some embodiments, the regeneration mechanism 300 includes a regeneration duct 310, a regeneration filter 320, a waste heat exchanger 330, a regeneration fan 340, and a regeneration exhaust duct 350. When the regeneration fan is working, outside air enters the regeneration duct 310, is filtered by the regeneration filter 320, and then enters the waste heat exchanger 330. The air absorbs heat from the waste heat exchanger 330 and is converted into hot air. The hot air dehydrates the adsorbent 120 covered by the regeneration area 102 to regenerate the adsorbent 120. The hot air is finally discharged from the regeneration exhaust duct 350.
[0051] The technical features of the above embodiments can be combined in any way.
