[0002] The dehumidification wheel absorbs moisture from the air, reducing the humidity of the air after passing through the dehumidification wheel, thereby achieving a dehumidification effect. Dehumidification wheels are widely used in industrial or commercial fields to dry air due to their advantages such as large dehumidification capacity. However, in order to achieve a greater dehumidification effect, the current wheel is large in size and inconvenient to transport and install. Moreover, when the processing capacity demand is not high, the use of a large-capacity, large-volume wheel will also cause unnecessary waste and cannot meet the differentiated needs of different users or different usage conditions. Summary of the invention

[0010] According to some preferred aspects of the present invention, the containing shell further comprises a cooling liquid inlet aligned with the channel of the wheel body located at the first position, and a cooling liquid outlet aligned with the channel of the wheel body located at the last position.

[0011] According to some preferred aspects of the present invention, the dehumidification wheel further comprises:

[0012] a reservoir having a chamber therein for containing a coolant;

[0013] A pipeline has one end connected to the reservoir, and the other end connected to the coolant inlet and the coolant outlet respectively.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0032] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. 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.

[0033] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 to Figure 2 As shown, this example provides a dehumidification wheel, which includes: a dehumidification wheel 100, a rotating shaft 130 and a containing shell 200.

[0035] Specifically, the dehumidifier wheel 100 includes at least two wheel bodies 110, which are coaxially arranged and sleeved on the rotating shaft 130, and each wheel body 110 is formed with and densely distributed with a plurality of channels; the wheel body 110 includes a first zone and a second zone, and the first zones of two adjacent wheel bodies 110 are aligned, and the second zones of two adjacent wheel bodies 110 are aligned; the rotating shaft 130 passes through the dehumidifier wheel 100, and the dehumidifier wheel 100 can rotate around the axis of the rotating shaft 130; the containing shell 200 has an opening 240 and a vent 230, and the rotating shaft 130 is rotatably mounted on the containing shell 200; the dehumidifier wheel 100 covers the opening 240, so that the first zone and the second zone have relative independence; one of the first zone and the second zone of the wheel body 110 is located in the containing shell 200, and the vent 230 is used for the gas to be dehumidified that passes through the channel of the first zone or the second zone located in the containing shell 200; the other channel located outside the containing shell 200 is used for the regeneration gas to pass through.

[0036] like Figure 1 As shown, the dehumidification wheel 100 is composed of a plurality of wheel bodies 110, and the structures and sizes of the plurality of wheel bodies 110 may be the same. The required number of wheel bodies 110 may be selected according to needs to form rotating 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 may be increased. When a dehumidification wheel 100 with a smaller volume and a smaller processing capacity is required, the number of wheel bodies 110 may be reduced, thereby meeting the differentiated needs of different users or different usage conditions.

[0037] In this example, "multiple" refers to two or more. The multiple wheels 110 can be coaxially arranged and fixed together by fasteners such as bolts.

[0038] Further, when the first zone is located in the containment shell 200, the first zone can be used as an adsorption dehumidification zone, wherein the vent hole 230 serves as the inlet of the gas to be dehumidified. The second zone is located outside the containment shell 200, and the second zone serves as a regeneration zone. After the gas to be dehumidified passes through the first zone, the humidity of the gas decreases, while the humidity of the first zone increases. The rotating shaft 130 is rotated, and the rotating shaft 130 drives the dehumidification wheel 100 to rotate. The first zone will rotate out of the containment shell 200, and the second zone will enter the containment shell 200 for dehumidification. At this time, the regeneration gas can be used to remove the moisture on the first zone to restore the adsorption capacity of the first zone. Without limitation, the regeneration gas is dry air, etc.

[0039] The containing 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 containing shell 200 to separate the first zone from the second zone, avoid mutual interference between the adsorption dehumidification process and the regeneration process, and ensure the dehumidification effect and the regeneration effect.

[0040] Generally, the wheel body 110 is made of a honeycomb body, such as honeycomb ceramics or honeycomb fiber paper, etc. The holes on the honeycomb body are channels for airflow to pass through to achieve dehumidification or regeneration.

[0041] In this example, the wheel body 110 also includes:

[0042] The channel 120 is arranged along the axial direction of the wheel body 110, is located in the interval between the holes and is not connected with the holes, and the channels 120 of two adjacent wheel bodies 110 are connected.

[0043] Generally, the hole on the wheel body 110 is small. When multiple wheels 110 are arranged in parallel along the axial direction, the flow resistance will increase, affecting the dehumidification effect and increasing energy consumption. By providing the channel 120, the channel 120 can at least serve as the air flow channel 120 of the regeneration gas, reducing the flow resistance, reducing energy consumption, and at least ensuring the regeneration effect of the wheel body 110.

[0044] In this example, the channels 120 of at least two wheel bodies 110 are combined to form a straight line, a curve or a folded line. It is understandable that the shape of the channel 120 is not limited to the above straight line, curve or folded line. Among them, the curved or folded line channel 120 can prolong the contact time between the airflow and the wheel body 110, further ensuring the dehumidification effect.

[0045] In this example, the housing 200 further comprises a coolant inlet 210 aligned with the channel 120 of the wheel body 110 located at the first position, and a coolant outlet aligned with the channel 120 of the wheel body 110 located at the last position.

[0046] Generally, the coolant inlet 210 and the vent hole 230 are arranged at intervals. After the regenerated first zone or second zone enters the containment shell 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 hole 230 are opened at different times. The coolant inlet 210 is used to introduce the coolant 320 into the channel 120, and the vent hole 230 is used to introduce the gas to be dehumidified into the air hole of the wheel body 110.

[0047] like Figure 1 As shown, multiple wheels 110 are connected end to end, and the wheel 110 located at the head first contacts the gas to be dehumidified first, while the wheel 110 located at the tail contacts the gas to be dehumidified last. After the first zone (or second zone) located outside is regenerated by the regeneration gas, it enters the containment shell 200, and before the next round of dehumidification, the first zone (or second zone) can be cooled by the coolant 320 flowing through the channel 120 to reduce the temperature of the wheel 110 and achieve the purpose of low-temperature dehumidification.

[0048] Since the channel 120 is located in the interval between the holes and is not connected to the holes, the coolant 320 can reduce the temperature of the wheel body 110 and ensure the moisture absorption capacity of the wheel body 110 while minimizing the interference with other parts of the wheel body 110. At the same time, it can also reduce the time required for the coolant 320 to evaporate from other areas of the wheel body 110 except the channel 120, thereby reducing the time required for the cooling operation.

[0049] Without limitation, the cooling liquid 320 is water, ethanol or ethyl acetate. The volatility of water, ethanol or ethyl acetate can be used to accelerate the temperature reduction. Alternatively, the cooling liquid 320 can also be other cooling liquids.

[0050] In this example, the dehumidification wheel also includes:

[0051] A reservoir having a chamber therein for containing a cooling liquid 320;

[0052] The pipe 310 has one end connected to the reservoir, and the other end connected to the coolant inlet 210 and the coolant outlet.

[0053] like Figure 1 As shown, the coolant 320 can be circulated in the storage 300, the pipeline 310 and the channel 120, thereby avoiding the coolant 320 from affecting the channels of other parts of the wheel body 110 and affecting the dehumidification effect.

[0054] In this example, the bottom of the container 200 also has a liquid outlet 220. Figure 1 As shown, if the humidity of the gas to be dehumidified is high, water may drip downward under the action of gravity and gather at the bottom of the containment shell 200. At this time, the liquid outlet 220 can be used to discharge the water to avoid water accumulation in the containment shell 200.

[0055] In this example, the dehumidification wheel also includes:

[0056] The adsorbent is at least located on the surface of the wheel body 110 .

[0057] The wheel body 110 can utilize its porous properties to perform adsorption and dehumidification, and the use of an adsorbent can further improve the dehumidification effect of the wheel body 110. The adsorbent includes but is not limited to molecular sieves, silica gel or lithium chloride.

[0058] In another embodiment, the dehumidification 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 the two ends of the dehumidification wheel 100 outside the containment shell 200, and the regeneration gas flowing through the regeneration heater 400 is introduced into the first zone or the second zone.

[0059] like Figure 2 The regeneration heater 400 heats the gas (such as dry air) to form a hot air flow, and uses the hot air flow to remove the moisture on the first zone or the second zone, thereby achieving the purpose of regenerating the first zone or the second zone.

[0060] In this example, the dehumidification wheel also includes:

[0061] The driving motor is connected to the rotating shaft 130 and drives the rotating shaft 130 to rotate. The dehumidification wheel rotates with the rotation of the rotating shaft 130, and the first area and the second area extend into the accommodating shell 200 alternately with the rotation of the rotating shaft 130.

[0062] like Figure 2 As shown, when the first zone is used as the adsorption dehumidification zone, the second zone is used 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.

[0063] In summary, in the dehumidification wheel provided by the present invention, the dehumidification wheel 100 is composed of a plurality of wheel bodies 110, and the required number of wheel bodies 110 can be selected as needed to form wheels of different sizes, thereby 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 housing 200, the first zone serves as an adsorption dehumidification zone, and the second zone serves as a regeneration zone, and vice versa, thereby ensuring the dehumidification effect on the air.

[0064] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
