[0035] Reference will now be made to the drawings Figures 1-6 The dehumidification device 100 according to the embodiments of the present application is described, which can be applied to the field of industrial dehumidification technology, and can be applied to archives, libraries, factory workshops, warehouses, computer rooms and other environments with humidity requirements, so as to reduce the humidity in the environment by the dehumidification device 100 in the present application.

[0036] The dehumidification device 100 according to the embodiments of the present application comprises a cabinet body 1 and a plurality of dehumidification film assemblies 2.

[0037] In combination with Figure 1 and Figure 3 It is shown that the cabinet body 1 has a cavity 101, and the plurality of dehumidification film assemblies 2 are arranged in the cavity 101, and the cavity 101 can be used for gas to flow through to achieve the transfer and discharge of moisture.

[0038] In combination with Figure 1 and Figure 6 It is shown that the dehumidification film assembly 2 has a first dehumidification surface 201 and a second dehumidification surface 202, and the moisture can diffuse from the first dehumidification surface 201 to the side of the second dehumidification surface 202 in the same dehumidification film assembly 2, and the plurality of dehumidification film assemblies 2 are arranged in the cavity 101 in a first direction. That is, when the first dehumidification surface 201 of the dehumidification film assembly 2 is in contact with the moisture, the water molecules in the moisture can be diffused to the side of the second dehumidification surface 202, so that the air located on the side of the second dehumidification surface 202 of the dehumidification film assembly 2 carries away the water molecules, thereby achieving the effect of reducing humidity.

[0039] As Figure 1 and Figure 3As shown, in the first direction, two first dehumidification surfaces 201 of two dehumidification film assemblies 2 arranged adjacently are oppositely arranged, and the above two dehumidification film assemblies 2 are cooperated with the cabinet 1 to divide the cavity 101 to form a first dehumidification channel 103, and the cabinet 1 is provided with a first air inlet 1031 and a first air outlet 1032 which are communicated with the first dehumidification channel 103, the first air inlet 1031 is used for flowing the gas (such as high humidity gas with higher humidity) into the first dehumidification channel 103, and the first air outlet 1032 is used for discharging the gas in the first dehumidification channel 103.

[0040] At the first dehumidification channel 103, the first dehumidification surfaces 201 of the two dehumidification film assemblies 2 are towards the side of the first dehumidification channel 103, and the water molecules in the high humidity gas flowing through the first dehumidification channel 103 can be absorbed by the dehumidification film assemblies 2 and diffused to the side of the second dehumidification surface 202, under the action of the dehumidification film assemblies 2, the humidity of the gas in the first dehumidification channel 103 can be reduced, so that the content of water molecules in the gas discharged through the first air outlet 1032 is reduced.

[0041] As shown in Figure 1 and Figure 3 As shown, in the first direction, two second dehumidification surfaces 202 of two dehumidification film assemblies 2 arranged adjacently are oppositely arranged, and the above two dehumidification film assemblies 2 are cooperated with the cabinet 1 to divide the cavity 101 to form a second dehumidification channel 104, and the cabinet 1 is provided with a second air inlet 1041 and a second air outlet 1042 which are communicated with the second dehumidification channel 104, the second air inlet 1041 is used for flowing the gas (such as dry gas with lower humidity) into the second dehumidification channel 104, and the second air outlet 1042 is used for discharging the gas in the second dehumidification channel 104.

[0042] At the second dehumidification channel 104, the second dehumidification surfaces 202 of the two dehumidification film assemblies 2 are towards the side of the second dehumidification channel 104, and the gas flowing through the second dehumidification channel 104 can take away the water molecules at the second dehumidification surface 202 to reduce the humidity of the dehumidification film assemblies 2 at the second dehumidification surface 202, under the cooperation of the gas flowing through the second dehumidification channel 104 and the second dehumidification surface 202, the water molecules attached to the second dehumidification surface 202 in the second dehumidification channel 104 can be discharged through the second air outlet 1042.

[0043] Among them, the first dehumidification channel 103 and the second dehumidification channel 104 are arranged adjacently, that is, the humidity of the gas flowing through the first dehumidification channel 103 can be reduced by the dehumidification film assemblies 2, and the water molecules absorbed by the dehumidification film assemblies 2 can diffuse to the side of the second dehumidification surface 202, and the water molecules at the second dehumidification surface 202 can be taken away by the gas flowing through the second dehumidification channel 104 (that is, discharged from the second dehumidification channel 104 through the second air outlet 1042), thereby realizing the dehumidification function of the dehumidification device 100.

[0044] It can be understood that, under the characteristics of the dehumidification membrane assembly 2 itself, the water molecules in the first dehumidification channel 103 can diffuse to the side of the second dehumidification channel 104 through the dehumidification membrane assembly 2, and the water molecules on the dehumidification membrane assembly 2 are taken out of the second dehumidification channel 104 by the gas flowing through the second dehumidification channel 104, so as to realize the dehumidification function of the dehumidification device 100.

[0045] It should be noted that at present, the traditional dehumidification equipment has high energy consumption, large equipment floor area, and high difficulty in daily maintenance, such as the need to switch valves, component corrosion, etc. In the related art, the membrane method dehumidification technology is used for dehumidification, and the membrane method dehumidification technology is dehumidified by selecting the permeability of the membrane material, and the dehumidification membrane assembly is mainly a drying tube prepared by a hollow fiber membrane. The drying tube is suitable for small dehumidification space fields such as analysis gas or compressed gas, and cannot meet the needs of low cost, low energy consumption, high dehumidification efficiency and other needs of industrial gas dehumidification for dehumidification equipment.

[0046] In the present application, the dehumidification membrane assembly 2 cooperates with the cabinet 1 to divide the cavity 101 to form the first dehumidification channel 103 and the second dehumidification channel 104. The gas with high humidity can flow through the first dehumidification channel 103 to adsorb the water molecules in the gas flowing through the first dehumidification channel 103 through the dehumidification membrane assembly 2, reduce the humidity of the gas, and the purge gas (i.e. relatively dry gas) can flow through the second dehumidification channel 104 and take the water molecules in the second dehumidification channel 104 out, realizing the dehumidification function of the dehumidification device 100. That is, the first air inlet 1031 of the first dehumidification channel 103 can be in communication with the environment requiring dehumidification, so as to transport the high-humidity gas in the environment to the first dehumidification channel 103, so that the humidity in the environment can be discharged through the first air outlet 1032 and the second air outlet 1042. At the same time, as the gas in the second dehumidification channel 104 is discharged, the water vapor at the second dehumidification surface 202 is taken away and discharged in time, which can reduce the water vapor concentration on the side of the second dehumidification surface 202, so that the water vapor in the first dehumidification channel 103 can diffuse from the side of the first dehumidification surface 201 to the side of the second dehumidification surface 202 under the concentration difference of the dehumidification membrane assembly 2.

[0047] It can be understood that the water molecules in the gas in the environment requiring dehumidification can easily pass through the dehumidification membrane assembly 2 (i.e. the water molecules can diffuse from the first dehumidification surface 201 to the side of the second dehumidification surface 202), and other substances are difficult to pass through the dehumidification membrane assembly 2. The water molecules in the dehumidification membrane assembly 2 are desorbed and taken out of the second dehumidification channel 104 by purging on the permeation side (i.e. the second dehumidification surface 202) of the dehumidification membrane assembly 2, realizing the dehumidification function of the dehumidification device 100.

[0048] The air flow flowing fast in the second dehumidification channel 104 can form a negative pressure or a relatively low pressure area at the second dehumidification surface 202, so as to take away the water vapor at the second dehumidification surface 202 by the air flow in the second dehumidification channel 104. Preferably, the air flow rate in the second dehumidification channel 104 is higher than the air flow rate in the first dehumidification channel 103.

[0049] Therefore, the dehumidification efficiency of the dehumidification device 100 is high, and only the air supply device needs to be connected to the first dehumidification channel 103 or the second dehumidification channel 104 to achieve air supply, that is, the energy consumption of the dehumidification device 100 is low when the dehumidification device 100 operates to achieve the dehumidification function, and the dehumidification membrane assembly 2 can be reused and has a long service life, thereby reducing the maintenance and maintenance costs.

[0050] As shown in Figure 1 and Figure 3 In some embodiments of the present application, a plurality of dehumidification membrane assemblies 2 are separated in the cavity 101 to form a first dehumidification channel 103 and a second dehumidification channel 104 arranged alternately in the first direction. Therefore, a plurality of first dehumidification channels 103 and a plurality of second dehumidification channels 104 can be formed in the cavity 101 by the plurality of dehumidification membrane assemblies 2, so that rapid dehumidification can be achieved by cooperation of the first dehumidification channel 103 and the second dehumidification channel 104, and the dehumidification efficiency of the dehumidification device 100 is improved.

[0051] As shown in Figure 1 and Figure 3 The first dehumidification channel 103 and the second dehumidification channel 104 are arranged adjacently, and preferably, the number of the second dehumidification channels 104 is one more than the number of the first dehumidification channels 103, so that each first dehumidification channel 103 is arranged with one second dehumidification channel 104 on each side in the first direction, so as to ensure that the moisture attached to the two dehumidification membrane assemblies 2 on both sides of the first dehumidification channel 103 in the first direction is taken away by the air flowing through the second dehumidification channel 104, thereby improving the dehumidification efficiency and dehumidification effect of the dehumidification device 100.

[0052] As shown in Figure 1As shown, in some embodiments of the present application, the first air outlet 1032 and the first air inlet 1031 are arranged opposite to each other in the second direction, and a baffle 3 is arranged in the first dehumidification channel 103. The baffle 3 can increase the length of the gas flow path in the first dehumidification channel 103, increase the passing time of the gas flowing through the first dehumidification channel 103 in the first dehumidification channel 103, so that the gas can fully contact the first dehumidification surface 201, and improve the water molecule adsorption effect of the dehumidification membrane assembly 2 on the gas flowing through the first dehumidification channel 103. At the same time, the second air outlet 1042 and the second air inlet 1041 are arranged opposite to each other in the second direction, so that the gas entering the second dehumidification channel 104 through the second air inlet 1041 can fully contact the second dehumidification surface 202 during flowing through the second dehumidification channel 104, and improve the effect of the gas carrying water molecules out of the second dehumidification channel 104.

[0053] The first direction is perpendicular to the second direction. Referring to Figure 1 The first direction is also Figure 1 The vertical direction of the cabinet 1 shown in Figure 1 The length direction of the cabinet 1 described in It can be understood that the air inlet structure (i.e. the first air inlet 1031 and the second air inlet 1041 described above) and the air outlet structure (i.e. the first air outlet 1032 and the second air outlet 1042 described above) are arranged on two side walls of the cabinet 1 in the second direction, respectively, so as to prolong the flow path length of the gas in the first dehumidification channel 103 and the second dehumidification channel 104, and improve the dehumidification effect. At the same time, the air inlet structure and the air outlet structure can avoid the cabinet door 12 and other structures of the cabinet 1.

[0054] As Figure 1 shown, in some embodiments of the present application, the first air outlet 1032 and the second air inlet 1041 are arranged on the same side of the cabinet 1 in the second direction, and the second air outlet 1042 and the first air inlet 1031 are arranged on the same side of the cabinet 1 in the second direction.

[0055] It can be understood that the first air inlet 1031 can be connected with the first air supply device, so as to transport the air in the environment to be dehumidified to the first air inlet 1031 through the first air supply device; the second air inlet 1041 can be connected with the second air supply device, so as to transport dry gas into the second dehumidification channel 104 through the second air supply device.

[0056] The first air outlet 1032 and the second air outlet 1042 are used to discharge the gas in the first dehumidification channel 103 and the second dehumidification channel 104, respectively. The first air outlet 1032 and the second air outlet 1042 can be connected to air guide structures. The connection method of the air guide structures connected to the first air outlet 1032 and the second air outlet 1042 and the specific construction of the air guide structures are not specifically limited here.

[0057] In some embodiments of this application, the first air outlet 1032 can be selectively connected to the second air inlet 1041 through a pipeline structure, so that the gas dehumidified in the first dehumidification channel 103 (i.e., the gas with reduced humidity) is used as the purging gas to be delivered to the second dehumidification channel 104 to carry out the water vapor in the second dehumidification channel 104.

[0058] It is understandable that the gas discharged through the first air outlet 1032 has already flowed through the first dehumidification channel 103, meaning that the humidity of the gas has decreased, thus making it suitable as purge gas for the second dehumidification channel 104. However, the purge gas supplied to the second dehumidification channel 104 through the second air inlet 1041 is not limited to this; other dry gases can also be used as purge gas. No specific limitations are made on the type of purge gas here.

[0059] like Figure 3 and Figure 3 As shown in some embodiments of this application, each first dehumidification channel 103 is provided with multiple baffles 3. The multiple baffles 3 are arranged at intervals along the second direction in the first dehumidification channel 103, and any two adjacent baffles 3 are staggered in the first direction. In this way, the baffles 3 restrict the gas flow path in the first dehumidification channel 103, thereby increasing the flow path length of the gas from the first air inlet 1031 through the first dehumidification channel 103 to the first air outlet 1032. This allows the gas in the first dehumidification channel 103 to fully contact the first dehumidification surface 201 of the dehumidification membrane assembly 2, thereby improving the adsorption effect of the dehumidification membrane assembly 2 on water vapor in the gas in the first dehumidification channel 103 and reducing the humidity of the gas flowing through the first dehumidification channel 103.

[0060] It is understandable that the first air inlet 1031 and the first air outlet 1032 are arranged on both sides of the cabinet 1 in the second direction. That is, the multiple baffles 3 arranged at intervals along the second direction can effectively restrict the gas flow, forming a labyrinth structure within the first dehumidification channel 103, thus extending the path length of the gas flow from the first air inlet 1031 to the first air outlet 1032. (Refer to...) Figure 3 As shown, the two baffles 3 arranged in a staggered manner in the first direction can define an S-shaped flow path in the first dehumidification channel 103 to extend the flow path of the gas in the first dehumidification channel 103.

[0061] As shown in Figure 3 some embodiments of the present application, the flow cross-sectional dimension of the second air inlet 1041 is S1, the flow cross-sectional dimension of the second air outlet 1042 is S2, and the relationship S1=S2 is satisfied, so as to ensure the gas flow effect at the second dehumidification channel 104, and the gas in the second dehumidification channel 104 can maintain uniform flow.

[0062] As shown in Figure 3 some embodiments of the present application, the flow cross-sectional dimension of the first air inlet 1031 is S3, the flow cross-sectional dimension of the first air outlet 1032 is S4, and the relationship 1.2S4≤S3≤2S4 is satisfied, so as to improve the gas flow effect at the first dehumidification channel 103.

[0063] It can be understood that, since the flow cross-sectional dimension of the first air inlet 1031 is greater than the flow cross-sectional dimension of the first air outlet 1032, the pressure in the first dehumidification channel 103 can be increased to a certain extent, and the contact effect of the gas in the first dehumidification channel 103 with the first dehumidification surface 201 is improved, so that the dehumidification membrane assembly 2 can better absorb water vapor.

[0064] It should be noted that, if the flow cross-sectional dimension S3 of the first air inlet 1031 is too large compared with the flow cross-sectional dimension S4 of the first air outlet 1032, the pressure in the first dehumidification channel 103 will be too large, and the problem of deformation or rupture of the dehumidification membrane assembly 2 caused by excessive pressure may occur.

[0065] As shown in Figure 4 some embodiments of the present application, the flow cross-sectional dimension of the second air inlet 1041 is S1, the flow cross-sectional dimension of the first air outlet 1032 is S4, and the relationship 0.3S4≤S1≤0.6S4 is satisfied.

[0066] It should be noted that, in some embodiments described above, the first air outlet 1032 can be in communication with the second air inlet 1041, that is, the gas discharged through the first air outlet 1032 can flow into the second dehumidification channel 104 through the second air inlet 1041. Meanwhile, under the same gas flow, the smaller the flow cross-sectional dimension, the faster the flow rate of the gas, and the efficiency of water vapor carried away by the gas can also be improved. Therefore, when S1 and S4 satisfy the above parameter range, the flow rate of the gas discharged from the first air outlet 1032 to the second dehumidification channel 104 through the second air inlet 1041 can be increased, and the gas discharged through the first dehumidification channel 103 can be used as purge gas to carry away the water vapor in the second dehumidification channel 104.

[0067] It should be noted that, the relationship of S1, S2, S3 and S4 described above can be satisfied simultaneously.

[0068] In combination Figure 5 And Figure 4 As shown in FIG. 1, in some embodiments of the present application, the dehumidification film assembly 2 comprises a frame assembly 21 and a dehumidification film 22.

[0069] The frame assembly 21 has a mounting groove for accommodating and arranging the dehumidification film 22.

[0070] Further, the dehumidification film 22 has a first dehumidification surface 201 and a second dehumidification surface 202, and the dehumidification film 22 is arranged in the mounting groove to be fixed by the frame assembly 21. Referring to Figure 6 As shown in FIG. 1, the frame assembly 21 can wrap the dehumidification film 22 in the circumferential direction, and the frame assembly 21 can expose at least part of the first dehumidification surface 201 and at least part of the second dehumidification surface 202 to ensure the contact and cooperation effect of the gas with the dehumidification film 22.

Figure 5 The protective layer 221 can be configured as a substrate with a grid, a plurality of pores or micropores to protect the dehumidification layer 222 from rupture through the protective layer 221. At the same time, the water vapor in the first dehumidification channel 103 can pass through the avoidance structure (such as micropores, grids, etc.) on the protective layer 221 and cooperate with the dehumidification layer 222, so that the water vapor can be adsorbed by the dehumidification layer 222 and diffused to the side of the second dehumidification surface 202.
