However, in order to obtain a relatively large dehumidification effect, the current rotor is relatively large in size, which is not convenient for transportation and installation. Moreover, in the case of a low demand for the processing volume, using a large - processing - volume and large - size rotor will also cause unnecessary waste and cannot meet the differentiated needs of different users or different usage states.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] As Figures 1 to 2 shown, this example provides a dehumidifying rotor, which includes a dehumidifying wheel 100, a rotating shaft 130, and a housing 200.

[0036] Specifically, the dehumidification wheel 100 includes at least two wheel bodies 110. The at least two wheel bodies 110 are coaxially arranged and sleeved on the rotating shaft 130, and a plurality of channels are formed and densely distributed on each wheel body 110. The wheel body 110 includes a first area and a second area, and the first areas of two adjacent wheel bodies 110 are aligned, and the second areas of two adjacent wheel bodies 110 are aligned. The rotating shaft 130 passes through the dehumidification wheel 100, and the dehumidification wheel 100 can rotate around the axis of the rotating shaft 130. The accommodating shell 200 has an opening 240 and ventilation holes 230, and the rotating shaft 130 is rotatably installed on the accommodating shell 200. The dehumidification wheel 100 covers the opening 240, achieving the relative independence of the first area and the second area. One of the first area and the second area of the wheel body 110 is located inside the accommodating shell 200, and the ventilation holes 230 allow the gas to be dehumidified passing through the channels of the first area or the second area located inside the accommodating shell 200. The channels of the other located outside the accommodating shell 200 allow the regeneration gas to pass through.

[0037] As Figure 1 shown, the dehumidification wheel 100 is composed of a plurality of wheel bodies 110. The structures and sizes of the plurality of wheel bodies 110 can be the same, and the required number of wheel bodies 110 can be selected according to needs to form dehumidification wheels of different sizes. For example, when a dehumidification wheel 100 with a larger volume and a larger processing capacity is required, the number of wheel bodies 110 can be increased. When a dehumidification wheel 100 with a smaller volume and a smaller processing capacity is required, the number of wheel bodies 110 can be reduced, meeting the differentiated requirements of different users or different usage states.

[0038] In this example, "a plurality of" means two or more. The plurality of wheel bodies 110 can be coaxially arranged and fixed together by fasteners such as bolts.

[0039] Further, when the first area is located inside the accommodating shell 200, the first area can be used as an adsorption dehumidification area, where the ventilation holes 230 serve as the inlet of the gas to be dehumidified. The second area is located outside the accommodating shell 200, and the second area serves as a regeneration area. When the gas to be dehumidified passes through the first area, the humidity of the gas decreases, while the humidity of the first area increases. Rotate the rotating shaft 130, and the rotating shaft 130 drives the dehumidification wheel 100 to rotate. The first area will rotate out of the accommodating shell 200, and the second area will enter the accommodating shell 200 for dehumidification. At this time, the moisture on the first area can be removed by using the regeneration gas to restore the adsorption capacity of the first area. Without limitation, the regeneration gas is dry air, etc.

[0040] The accommodating shell 200 is used to support the rotating shaft 130 and the dehumidification wheel 100 located on the rotating shaft 130. After the dehumidification wheel 100 covers the opening 240, it can seal the accommodating shell 200, separate the first area from the second area, avoid the mutual interference between the adsorption dehumidification process and the regeneration process, and ensure the dehumidification effect and the regeneration effect.

[0041] Generally, the wheel body 110 is made of a honeycomb body, such as honeycomb ceramics or honeycomb fiber paper. The holes on such a honeycomb body are the channels for the air flow to pass through to achieve the functions of dehumidification or regeneration.

[0042] In this example, the wheel body 110 further includes:

[0043] The channels 120 are arranged along the axial direction of the wheel body 110, located in the intervals between the channels and not communicating with the channels, and the channels 120 of two adjacent wheel bodies 110 are communicated.

[0044] Generally, the channels on the wheel body 110 are small. When multiple wheel bodies 110 are arranged side by side along the axial direction, it will cause an increase in the flow resistance, affect the dehumidification effect, and increase the energy consumption. By setting the channels 120, the channels 120 can at least serve as the air flow channels for the regeneration gas, reduce the flow resistance, lower the energy consumption, and at least ensure the regeneration effect of the wheel body 110.

[0045] In this example, the channels 120 of at least two wheel bodies 110 form a straight line, a curve, or a broken line after combination. It can be understood that the shape of the channels 120 is not limited to the above straight line, curve, or broken line. Among them, the channels 120 such as curves or broken lines can extend the contact time between the air flow and the wheel body 110, and further ensure the dehumidification effect.

[0046] In this example, the housing 200 also has a coolant inlet 210 aligned with the channel 120 of the first wheel body 110 in the first position, and a coolant outlet aligned with the channel 120 of the wheel body 110 in the last position.

[0047] Generally, the coolant inlet 210 and the vent holes 230 are distributed at intervals. After the first zone or the second zone after regeneration enters the housing 200, it is first cooled by the coolant 320, and then the gas to be dehumidified is introduced. Therefore, the coolant inlet 210 and the vent holes 230 are opened at different times. The coolant inlet 210 is used to introduce the coolant 320 into the channel 120, and the vent holes 230 are used to introduce the gas to be dehumidified into the air holes of the wheel body 110.

[0048] As Figure 1 shown, multiple wheel bodies 110 are connected end to end. The first wheel body 110 in the first position first contacts the gas to be dehumidified, and the wheel body 110 in the last position finally contacts the gas to be dehumidified. When the first zone (or the second zone) located outside is regenerated by the regeneration gas and enters the housing 200, and before the next round of dehumidification, the first zone (or the second zone) can be cooled by the coolant 320 flowing through the channel 120 to reduce the temperature of the wheel body 110 and achieve the purpose of low-temperature dehumidification.

[0049] Since the channel 120 is located within the interval between the pores and is not in communication with the pores, the coolant 320 can reduce the temperature of the wheel body 110 while minimizing interference with other parts of the wheel body 110, ensuring the moisture absorption capacity of the wheel body 110. At the same time, it can also reduce the time required for the coolant 320 to volatilize in other areas of the wheel body 110 except for the channel 120, reducing the time required for the cooling operation.

[0050] Without limitation, the coolant 320 is water, ethanol or ethyl acetate. By utilizing the volatile nature of water, ethanol or ethyl acetate, the temperature reduction can be accelerated. Alternatively, the coolant 320 can also be other cooling liquids.

[0051] In this example, the dehumidifying rotating wheel further includes:

[0052] A reservoir having a chamber for containing the coolant 320 therein;

[0053] A pipe 310 having one end in communication with the reservoir and the other end in communication with the coolant inlet 210 and the coolant outlet respectively.

[0054] As Figure 1 shown, the coolant 320 can be recycled within the memory 300, the pipe 310 and the channel 120, avoiding the influence of the coolant 320 on the pores of other parts of the wheel body 110 and avoiding affecting the dehumidifying effect.

[0055] In this example, the bottom of the accommodating shell 200 further has a liquid outlet 220. As Figure 1 shown, if the humidity of the gas to be dehumidified is relatively high, water may drip downward under the action of gravity and accumulate at the bottom of the accommodating shell 200. At this time, the water can be discharged by using the liquid outlet 220 to avoid water accumulation in the accommodating shell 200.

[0056] In this example, the dehumidifying rotating wheel further includes:

[0057] An adsorbent, and the adsorbent is at least located on the surface of the wheel body 110.

[0058] The wheel body 110 can perform adsorption dehumidification by utilizing its porous properties, and the use of the adsorbent can further improve the dehumidifying effect of the wheel body 110. The adsorbent includes but is not limited to molecular sieves, silica gel or lithium chloride, etc.

[0059] In other embodiments, the dehumidifying rotating wheel further includes: a regeneration heater 400 and a regeneration fan 500. The regeneration heater 400 and the regeneration fan 500 are respectively located at both ends of the dehumidifying wheel 100 outside the accommodating shell 200, and introduce the regeneration gas flowing through the regeneration heater 400 into the first zone or the second zone.

[0060] As Figure 2As shown, where the arrow indicates the air flow direction. The regeneration heater 400 heats the gas (such as dry air) to form a hot air flow, and uses the hot air flow to carry away the moisture on the first zone or the second zone, achieving the purpose of regenerating the first zone or the second zone.

[0061] In this example, the dehumidifying rotary wheel further includes:

[0062] A drive motor, connected to the rotating shaft 130 and driving the rotating shaft 130 to rotate. The dehumidifying rotary wheel rotates with the rotation of the rotating shaft 130, and the first zone and the second zone alternately extend into the accommodation shell 200 with the rotation of the rotating shaft 130.

[0063] As Figure 2 shown, when the first zone serves as the adsorption dehumidification zone, the second zone serves as the regeneration zone, and vice versa. The area sizes of the first zone and the second zone can be adjusted as needed. For example, the areas of the first zone and the second zone are equal.

[0064] In summary, in the dehumidifying rotary wheel provided by the present invention, the dehumidifying wheel 100 is composed of a plurality of wheel bodies 110. The required number of wheel bodies 110 can be selected according to needs to form rotary wheels of different sizes, meeting the differentiated needs of different users or different usage states. Moreover, the wheel body 110 is divided into a first zone and a second zone. When the first zone is located in the accommodation shell 200, the first zone serves as the adsorption dehumidification zone and the second zone serves as the regeneration zone, and vice versa, ensuring the dehumidification effect on the air.

[0065] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
