[0029] Air humidity affects human productivity and daily life. Air dehumidification is an important process to maintain indoor comfortable environment and ensure product quality and performance. At present, vapor compression mechanical refrigeration system is still the main choice for realizing dehumidification and cooling function worldwide. However, the main disadvantage of vapor compression refrigeration system is that it consumes a large amount of electric energy, and there are also problems of chemical refrigerant pollution of the environment, ozone depletion, global warming, low utilization rate of natural cold source. Vapor compression refrigeration system controls the temperature and humidity of supply air through cooling, dehumidification and reheating process, in which process, the air temperature is lowered below the dew point temperature to achieve the target humidity level, and the air temperature is increased to the target value through the reheating device. Cooling-reheating is a cooling and dehumidification process of heat offset, resulting in a large amount of energy waste.

[0030] The temperature and humidity independent control system provides a solution to solve the above problems, which reduces the additional energy consumption caused by the reheating process by separately processing the air temperature and humidity.

[0031] The temperature and humidity independent control system is mainly composed of a temperature processing system and a humidity processing system. The temperature processing system is responsible for bearing the sensible heat load of the indoor, and the humidity processing system is responsible for bearing the latent heat load. The solid desiccant cooling system is one of the temperature and humidity independent control systems, and has a competitive advantage due to simple structure, low cost, easy maintenance and use of environment-friendly desiccant. The research results of the solid desiccant cooling system show that the system has good energy-saving potential. In the hot and humid areas in southern China, in order to realize the efficient and energy-saving temperature and humidity independent system, it is necessary to have a high-efficiency dehumidification device. In terms of principle, the solid desiccant dehumidification is to dehumidify the air by using the solid adsorbent, and the application of the adsorbent is considered as a kind of renewable energy. The moisture in the air forms a molecular layer on the surface of the adsorbent by Van der Waals force to realize air dehumidification. The solid desiccant dehumidification has the advantages of non-corrosiveness, low investment cost, small floor area and simple operation requirements, and can be regenerated by using solar renewable energy and waste heat, and has more energy-saving and environmental protection benefits than the traditional vapor compression refrigeration system and the liquid desiccant cooling system.

[0032] At present, other mainstream solid desiccant devices mainly include a desiccant wheel, a desiccant heat exchanger and a fluidized bed dehumidification device.

[0033] Although the desiccant wheel can realize continuous circulation of "dehumidification-regeneration-dehumidification", and has the convenience of combination with other cooling systems, due to the relatively complex system structure, there are problems such as additional moving parts, frequent switching between the dehumidification and regeneration zones, great influence of the wheel speed, and low dehumidification effect and dehumidification capacity.

[0034] The desiccant heat exchanger device includes fin-coated desiccant material, and due to the limited number of fin-coated desiccant materials, the dehumidification capacity of the desiccant heat exchanger is relatively small, and the desiccant heat exchanger cannot realize simultaneous dehumidification and regeneration, and the replacement of the desiccant material is relatively complicated, which are some key problems faced by the desiccant heat exchanger.

[0035] The fluidized bed has high heat and mass transfer efficiency, and can avoid the problem that the adsorption heat is not easy to dissipate, and can realize continuous dehumidification, but the experimental device, equipment and dehumidification material are relatively harsh, the adsorption time is short, and the bed body is prone to wear, which hinders further engineering application.

[0036] Therefore, developing a high-efficiency and energy-saving solid desiccant device is the key to realizing a high-efficiency solid desiccant cooling system. The utility model discloses a double-layer multi-stage fixed-bed air dehumidification device based on the above background.

[0051] Embodiment three

[0052] As shown in Figure 1 and Figure 2As shown, further, the dehumidification box 1 has two opposite and spaced side walls in the first direction. The inlet 101 is formed on one side wall of the dehumidification box 1 in the first direction, and the outlet 103 is formed on the other side wall of the dehumidification box 1 in the first direction; the dehumidification device includes a plurality of dehumidification devices 11 arranged in the first direction. The number of dehumidification devices 11 is multiple. The plurality of dehumidification devices 11 are arranged in the first direction. That is to say, a plurality of dehumidification devices 11 are arranged in each dehumidification box 1, and each dehumidification device 11 is provided with a plurality of air flow holes 1113. In the process of air flow flowing from the inlet 101 to the outlet 103, the flow path of the air flow is approximately along the first direction, and the plurality of dehumidification devices 11 adsorb moisture and dry the gas, thereby performing multi-stage dehumidification on the air flow and improving the dehumidification efficiency and dehumidification effect.

[0053] As shown in Figure 1 , Figure 2 and Figure 3 , further, the dehumidification material container 111 extends in the second direction, and the dehumidification material container 111 has a plurality of partitions 1111 arranged in the second direction. The second direction is perpendicular to the first direction. The partitions 1111 divide the dehumidification material container 111 into different cells, and each cell is filled with an equal amount of dehumidification material 112.

[0054] As shown in Figure 1 and Figure 2As shown, the inner cavity 102 further includes a first sidewall 1021 and a second sidewall 1022 that are opposite to and separated from each other in a third direction; a first rib 1023 is connected to the first sidewall 1021, and the first rib 1023 is spaced apart from the second sidewall 1022 to allow airflow; a second rib 1024 is connected to the second sidewall 1022, and the second rib 1024 is spaced apart from the first sidewall 1021 to allow airflow; there are multiple first ribs 1023 and multiple second ribs 1024, and the multiple first ribs 1023 and multiple second ribs 1024 are alternately arranged along a first direction. In the third direction, the airflow flows along the first rib 1023 to the second sidewall 1022, then flows from the gap between the first rib 1023 and the second sidewall 1022 to the second rib 1024, and then continues along the second rib 1024 to the first sidewall 1021, then flows out from the gap between the first sidewall 1021 and the second rib 1024 back to the first rib 1023, and so on. The airflow path is, on the one hand, along the direction from the inlet 101 to the outlet 103 and parallel to the first direction, and on the other hand, it flows back and forth in the third direction, thus the airflow path in the inner cavity 102 is "U" shaped. The first rib 1023 is provided with dehumidifying material containers 111 on both sides of the first direction, and the second rib 1024 is provided with dehumidifying material containers 111 on both sides of the first direction. The air passage 1113 is opened on the container wall of the dehumidifying material container 111 in the third direction. Multiple dehumidifying devices 11 are arranged in the airflow path. Water molecules in the airflow are absorbed by the dehumidifying devices 11, improving the dehumidification efficiency. The third direction, the first direction, and the second direction are perpendicular to each other.

[0055] like Figure 3 As shown, the air vent 1113 of the dehumidifying material container 111 is specifically designed such that the bottom of the dehumidifying material 112 is constructed using a nylon mesh, and the top of the dehumidifying material container 111 is open. This reduces resistance to airflow and improves the dehumidification effect.

[0056] like Figure 1 and Figure 2 As shown, in a preferred example, in the third direction, the dehumidification device 11 is disposed at the end of the first rib 1023 away from the first sidewall 1021, and the dehumidification device 11 is disposed at the end of the second rib 1024 away from the second sidewall 1022. Thus, the airflow path in the third direction exhibits a back-and-forth flow, allowing the airflow to pass perpendicularly through the dehumidification material, ensuring sufficient contact between the airflow and the dehumidification material.

[0057] like Figure 1 and Figure 2 As shown, in a preferred example, a dehumidification device 11 is provided between adjacent first ribs 1023 and second ribs 1024.

[0058] Further, in the second direction, two ends of the first rib plate 1023 in the direction correspondingly connect two opposite and spaced side walls of the inner cavity 102 in the direction, that is, one end of the first rib plate 1023 in the second direction connects one side wall of the inner cavity 102 in the second direction, and the other end of the first rib plate 1023 in the second direction connects the other side wall of the inner cavity 102 in the second direction; in the second direction, two ends of the second rib plate 1024 in the direction correspondingly connect two opposite and spaced side walls of the inner cavity 102 in the direction, that is, one end of the second rib plate 1024 in the second direction connects one side wall of the inner cavity 102 in the second direction, and the other end of the second rib plate 1024 in the second direction connects the other side wall of the inner cavity 102 in the second direction. Therefore, more air flow is guided by the first rib plate 1023 and the second rib plate 1024 to flow in the third direction and pass through the dehumidification device 11.

[0059] In a specific example, the dehumidification box 1 is a cuboid. The dehumidification box 1 is spliced by 15mm-thick acrylic plates. The outer dimensions of the dehumidification box 1 are 1150mm×780mm×950mm (length×width×height).

[0060] Example Four

[0061] As shown in Figure 1 and Figure 2 Further, the inner cavity 102 is also provided with a plurality of support frames 1025, each of which is arranged to extend in the second direction; the support frames 1025 are in sliding fit with the dehumidification material container 111. The support frames 1025 can be arranged at one end of the first rib plate 1023 away from the first side wall 1021, and the support frames 1025 can be arranged at one end of the second rib plate 1024 away from the second side wall 1022.

[0062] Example Five

[0063] Further, the dehumidification material 112 is silica gel. The silica gel material is non-toxic and odorless, does not contain harmful substances, and has stable chemical properties, good adsorption effect, and low regeneration temperature. Compared with liquid dehumidification, the chemical properties of the silica gel material are more stable, and it can better prevent equipment corrosion and environmental problems caused by leakage of the dehumidification material.

[0064] As shown in Figure 1 and Figure 2 Further, the double-layer multi-stage fixed-bed air dehumidification device 100 further comprises a mobile vehicle 5, and the dehumidification box 1, the distribution static pressure tank 2, the collection static pressure tank 3, and the fan 4 are arranged on the mobile vehicle 5, which improves the flexibility of the double-layer multi-stage fixed-bed air dehumidification device 100, can be conveniently combined with other cooling systems to form a temperature and humidity independent control air conditioning system, serves as a replacement technical solution for the large energy-consuming steam compression refrigeration system, and is conducive to energy saving and environmental protection.

The dehumidification box 1 is configured as a cuboid with a length x width x height of 1150mm x 780mm x 950mm (first direction x second direction x third direction). In order to improve the air processing capacity and dehumidification efficiency, the dehumidification box 1 is arranged in two layers, and the size, material and working condition of each layer are completely the same. Each dehumidification box 1 is provided with five dehumidification devices 11, each of which comprises a dehumidification material container 111 and a plurality of dehumidification materials 112.
