[0002] Dehumidification equipment is widely used in certain locations, such as libraries, because they require a low-humidity environment. Dehumidification equipment typically uses a dehumidification wheel. The dehumidification wheel consists of a treatment zone and a regeneration zone.

[0030] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate exemplary embodiments of the present invention, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] The present application discloses a dehumidification device, referring to Figure 1 , which shows a schematic diagram of the connection components of a dehumidification device provided by an embodiment of the present invention. Dehumidification equipment can reduce the air humidity in certain places (such as places with collections) to prevent problems such as mold growth, corrosion, and damage to items caused by moisture.

[0032] Reference Figure 1 As shown, the dehumidification equipment includes a rotor treatment area 11, a rotor regeneration area 12, a dehumidification pipeline 21, a regeneration pipeline 22, a first control valve 54, a heating mechanism 30, a heat recovery mechanism 40 and a control module 50; wherein, the rotor treatment area 11 is provided on the dehumidification pipeline 21; a regeneration pipeline inlet, a first control valve 54, a heating mechanism 30, a rotor regeneration area 12 and a regeneration pipeline outlet are provided on the regeneration pipeline 22 in sequence; a first inlet 41 of the heat recovery mechanism 40 is communicated with the regeneration pipeline 22 between the rotor regeneration area 12 and the regeneration pipeline outlet; The second inlet 43 of the heat recovery mechanism 40 is connected to the regeneration pipeline 22 between the regeneration pipeline inlet and the first control valve 54; the second outlet 44 of the heat recovery mechanism 40 is connected to the regeneration pipeline 22 between the first control valve 54 and the heating mechanism 30, and the second outlet 44 of the heat recovery mechanism 40 is also connected to the regeneration pipeline 22 between the heating mechanism 30 and the wheel regeneration zone 12; the control module 50 is used to control the high-temperature regeneration gas flowing out of the second outlet 44 to directly enter the wheel regeneration zone 12, and / or enter the wheel regeneration zone 12 after passing through the heating mechanism 30.

[0033] The dehumidification equipment includes a dehumidification wheel 10, which is located within the dehumidification equipment and is divided into a wheel treatment zone 11 and a wheel regeneration zone 12. As the treated air passes through the wheel treatment zone 11, moisture in the treated air is absorbed by the hygroscopic medium in the dehumidification wheel 10, achieving a dehumidification effect. As the dehumidification wheel 10 absorbs a certain amount of moisture, it gradually approaches saturation. The treated air becomes dry and hot due to the reduction in moisture and the release of latent heat. Simultaneously, in the wheel regeneration zone 12, high-temperature regeneration gas passes through the dehumidification wheel 10 after dehumidification, evaporating the adsorbed moisture in the dehumidification wheel 10 and restoring its dry state, thereby restoring the dehumidification capacity of the dehumidification wheel 10. The dehumidification wheel 10 rotates continuously, alternating between the wheel treatment zone 11 and the wheel regeneration zone 12, achieving a continuous dehumidification process. The dehumidification wheel 10 can be divided into a wheel treatment area 11 and a wheel regeneration area 12 according to usage requirements. For example, 3 / 4 of the dehumidification wheel 10 is the wheel treatment area 11, and 1 / 4 of the dehumidification wheel 10 is the wheel regeneration area 12.

[0034] The dehumidification pipeline 21 and the regeneration pipeline 22 are used to transport air. Specifically, the portion of the dehumidification pipeline 21 located between the dehumidification pipeline inlet and the rotor treatment area 11 is used to transport treated air, and the portion of the dehumidification pipeline 21 located between the rotor treatment area 11 and the dehumidification pipeline outlet is used to transport dry air after the dehumidification wheel 10 absorbs moisture. The portion of the regeneration pipeline 22 located between the regeneration pipeline inlet and the rotor regeneration area 12 is used to transport regenerated air, and the portion of the regeneration pipeline 22 located between the rotor regeneration area 12 and the regeneration pipeline outlet is used to transport the rotor exhaust air that absorbs moisture in the rotor regeneration area 12. The materials used in the dehumidification pipeline 21 and the regeneration pipeline 22 can be set according to the requirements of use. For example, the dehumidification pipeline 21 is a metal pipe (such as a steel pipe, etc.), a plastic pipe (such as a polyethylene pipe, etc.), etc.

[0035] It can be understood that the first control valve 54, the heating mechanism 30, and the wheel regeneration zone 12 are arranged on the regeneration pipeline 22, and can be connected using accessories such as joints, elbows, tees, valves, flanges, and other possible methods. The embodiments of the present application do not make specific limitations on this.

[0036] When the dehumidification equipment of the embodiment of the present application is in use, the treated air enters the dehumidification pipeline 21 from the dehumidification pipeline inlet. During the process of the treated air passing through the wheel processing area 11, the moisture in the treated air is absorbed by the dehumidification wheel 10 and becomes dry air, and the dry air is discharged from the dehumidification pipeline outlet.

[0037] Regeneration air enters the regeneration pipeline 22 through the regeneration pipeline inlet, passes through the first control valve 54, and enters the heating mechanism 30. The heating mechanism 30 heats the regeneration air, raising its temperature. The heated regeneration air then flows out of the heating mechanism 30 and enters the rotor regeneration zone 12. The heated regeneration air absorbs moisture from the rotor regeneration zone 12, restoring the dry state and thus restoring the dehumidification capacity of the dehumidification rotor 10. After absorbing moisture, the heated regeneration air becomes rotor exhaust air with a certain temperature and humidity. The rotor exhaust air, which has a certain temperature and humidity, is discharged from the rotor regeneration zone 12 through the regeneration pipeline outlet.

[0038] In the embodiment of the present application, the dehumidification equipment is provided with a heat recovery mechanism 40. The rotor exhaust air, which has a certain temperature and humidity, discharged from the rotor regeneration zone 12 can also enter the heat recovery mechanism 40 through the first inlet 41 of the heat recovery mechanism 40 for heat exchange. The rotor exhaust air is cooled and then discharged from the first outlet 42 of the heat recovery mechanism 40. When the first control valve 54 is closed, the regeneration air entering the regeneration line 22 through the regeneration line inlet enters the heat recovery mechanism 40 through the second inlet 43 of the heat recovery mechanism 40. After heat exchange with the rotor exhaust air, which has a certain temperature and humidity, the temperature of the regeneration air is increased. The increased temperature of the regeneration air is then discharged from the second outlet 44 of the heat recovery mechanism 40. The increased temperature of the regeneration air discharged from the second outlet 44 of the heat recovery mechanism 40 can flow directly into the rotor regeneration zone 12, or can pass through the heating mechanism 30 before entering the rotor regeneration zone 12.

[0039] In an embodiment of the present application, the heat recovery mechanism 40 can recover the heat of the rotor exhaust air with a certain temperature and humidity discharged from the rotor regeneration zone 12, and use the heat to heat the regenerated air, thereby increasing the temperature of the regenerated air to make it regenerated air with a higher temperature. The regenerated air with a higher temperature flows directly into the rotor regeneration zone 12, or is further heated by the heating mechanism 30 and then enters the rotor regeneration zone 12. Both of these can reduce the energy required to heat the regenerated air to a preset temperature, thereby improving the energy utilization rate of the dehumidification equipment, reducing the energy waste caused by the direct discharge of the rotor exhaust air with a certain temperature and humidity, and reducing the energy consumption of the dehumidification equipment.

[0040] In some embodiments, reference Figure 1As shown, the dehumidification equipment also includes a first pipeline 23, a second pipeline 24 and a control module 50; one end of the first pipeline 23 is connected to the second outlet 44, and the other end of the first pipeline 23 is connected to the regeneration pipeline 22 between the heating mechanism 30 and the wheel regeneration zone 12; one end of the second pipeline 24 is connected to the second outlet 44, and the other end of the second pipeline 24 is connected to the regeneration pipeline 22 between the first control valve 54 and the heating mechanism 30; the control module 50 is respectively connected to the first pipeline 23 and the second pipeline 24, and the control module 50 is used to control the opening of the first pipeline 23 and the second pipeline 24 respectively.

[0041] In the present application, refer to Figure 1 As shown, the second outlet 44 of the heat recovery mechanism 40 is connected to the regeneration pipeline 22 between the heating mechanism 30 and the rotor regeneration zone 12 via the first pipeline 23. The second outlet 44 of the heat recovery mechanism 40 is also connected to the regeneration pipeline 22 between the first control valve 54 and the heating mechanism 30 via the second pipeline 24. The second inlet 43 of the heat recovery mechanism 40 is connected to the regeneration pipeline 22 between the regeneration pipeline inlet and the first control valve 54 via the fourth pipeline 28. For easier control, a seventh control valve 60 is also provided on the fourth pipeline 28.

[0042] In the dehumidification device, the control module 50 controls the openings of the first pipeline 23 and the second pipeline 24, respectively, to control the high-temperature regeneration gas flowing out of the second outlet 44 to directly enter the rotor regeneration zone 12, and / or to control the high-temperature regeneration gas flowing out of the second outlet 44 to be further heated by the heating mechanism 30 before entering the rotor regeneration zone 12. In other words, the direction of the high-temperature regeneration gas flowing out of the second outlet 44 is controlled by the control module 50. Since the temperature of the regeneration gas is related to the drying ability of the regeneration gas on the dehumidification rotor 10, the higher the regeneration gas temperature, the stronger the drying ability of the dehumidification rotor 10. The dryness of the dehumidification rotor 10 is related to the moisture absorption capacity of the dehumidification rotor 10. The higher the dryness of the dehumidification rotor 10, the stronger the moisture absorption capacity of the dehumidification rotor 10. The temperature of the high-temperature regeneration gas flowing out of the second outlet 44 when it directly enters the wheel regeneration zone 12 is lower than the temperature of the high-temperature regeneration gas flowing out of the second outlet 44 when it is further heated by the heating mechanism 30 and enters the wheel regeneration zone 12, which makes the moisture absorption capacity of the dehumidification wheel 10 different. The dehumidification equipment can adjust the direction of the high-temperature regeneration gas flowing out of the second outlet 44 according to the use requirements to meet the dehumidification requirements of the dehumidification equipment and be more energy-efficient.

[0043] In some embodiments, reference Figure 1As shown, the connection structure between the first pipeline 23 and the second pipeline 24 is as follows: one end of the second pipeline 24 is connected to the second outlet 44, and the other end of the second pipeline 24 is connected to the regeneration pipeline 22 between the first control valve 54 and the heating mechanism 30. One end of the first pipeline 23 is connected to the second pipeline 24, and the other end of the first pipeline 23 is connected to the regeneration pipeline 22 between the heating mechanism 30 and the rotor regeneration zone 12.

[0044] In some embodiments, the control module 50 includes a second control valve 55 and a third control valve 56. The second control valve 55 is disposed on the first pipeline 23 to control the opening of the first pipeline 23. The third control valve 56 is disposed on the second pipeline 24 to control the opening of the second pipeline 24. In the embodiment of the present application, controlling the opening of the first pipeline 23 by the second control valve 55 and controlling the opening of the second pipeline 24 by the third control valve 56 have the advantages of simple and convenient structure and precise control.

[0045] In some embodiments, the control module 50 also includes a control unit 51 and a first moisture content detection unit 61, and the first moisture content detection unit 61 is arranged between the wheel processing area 11 and the dehumidification pipeline outlet of the dehumidification pipeline 21; the control unit 51 is electrically connected to the first moisture content detection unit 61, the second control valve 55 and the third control valve 56 respectively, and the control unit 51 adjusts the opening of the first control valve 54 and the second control valve 55 according to the moisture content detected by the first moisture content detection unit 61.

[0046] The first moisture content detection unit 61 is used to detect the moisture content of the dry air passing between the rotor treatment zone 11 and the dehumidification pipeline outlet of the dehumidification pipeline 21, that is, to detect the moisture content of the dry air flowing out of the rotor treatment zone 11. The control unit 51 adjusts the openings of the first control valve 54 and the second control valve 55 based on the moisture content detected by the first moisture content detection unit 61. This can adjust the ratio of the high-temperature regeneration gas flowing out of the second outlet 44 directly entering the rotor regeneration zone 12 and the high-temperature regeneration gas flowing out of the second outlet 44 after being further heated by the heating mechanism 30 and then entering the rotor regeneration zone 12. In other words, the control unit 51 can control the temperature of the regeneration gas entering the rotor regeneration zone 12, adjust the drying capacity of the regeneration gas on the dehumidification rotor 10, and further adjust the moisture absorption capacity of the dehumidification rotor 10 to meet the dehumidification requirements of the dehumidification equipment.

[0047] In some embodiments, the first moisture content detection unit 61 can be selected based on usage requirements. For example, the first moisture content detection unit 61 is a first temperature and humidity sensor. The first temperature and humidity sensor is used to measure the temperature and humidity of the air to calculate the moisture content of the regenerated air based on the temperature and humidity. The specific calculation formula is a conventional calculation method and is not described in detail in this embodiment of the application.

[0048] In some embodiments, the dehumidification equipment also includes a third pipeline 25, and the control module 50 also includes a fourth control valve 57; one end of the third pipeline 25 is connected to the regeneration pipeline 22 between the wheel regeneration area 12 and the regeneration pipeline outlet, and the other end of the third pipeline 25 is connected to the first inlet 41, and a fourth control valve 57 is set on the third pipeline 25; the control unit 51 is also electrically connected to the fourth control valve 57, and the control unit 51 adjusts the opening of the fourth control valve 57 according to the moisture content detected by the first moisture content detection unit 61.

[0049] In the embodiment of the present application, adjusting the opening of the fourth control valve 57 can regulate the flow rate of the rotor exhaust air entering the heat recovery mechanism 40. When the flow rate of the rotor exhaust air entering the heat recovery mechanism 40 is high, the heat recovery mechanism 40 can recover more heat for heating the regeneration gas, significantly increasing the temperature of the regeneration gas. When the flow rate of the rotor exhaust air entering the heat recovery mechanism 40 is low, the heat recovery mechanism 40 can recover less heat for heating the regeneration gas, thereby reducing the increase in the regeneration gas temperature. Since a higher regeneration gas temperature increases the drying capacity of the dehumidification rotor 10, a higher degree of drying of the dehumidification rotor 10 increases its moisture absorption capacity. Therefore, by adjusting the opening of the fourth control valve 57 based on the moisture content detected by the first moisture content detection unit 61, the control unit 51 can adjust the moisture absorption capacity of the dehumidification rotor 10, thereby ensuring that the moisture content of the dry air flowing out of the rotor processing area 11 meets the required usage.

[0050] In a specific adjustment example, when the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the wheel treatment zone 11 is greater than a preset range, the second control valve 55 can be closed and the third control valve 56 can be opened, allowing the high-temperature regeneration gas flowing out of the second outlet 44 of the heat recovery mechanism 40 to be heated by the heating mechanism 30, further increasing the temperature before entering the wheel regeneration zone 12. This allows the regeneration gas to absorb more moisture from the dehumidification wheel 10, thereby increasing the dryness of the dehumidification wheel 10 and enhancing the moisture adsorption capacity of the dehumidification wheel 10, thereby reducing the moisture content of the dry air flowing out of the wheel treatment zone 11. If the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the wheel treatment zone 11 is still greater than the preset range after the third control valve 56 is fully opened, the temperature of the regeneration gas entering the wheel regeneration zone 12 can be further increased by increasing the opening of the fourth control valve 57 and increasing the gear of the heating mechanism 30, thereby further improving the dryness of the dehumidification wheel 10.

[0051] When the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the rotor treatment zone 11 is less than a preset range, the openings of the second control valve 55 and the third control valve 56 can be adjusted to reduce the flow rate of the high-temperature regeneration gas flowing out of the second outlet 44 of the heat recovery mechanism 40, which is further heated by the heating mechanism 30 before entering the rotor regeneration zone 12. When the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the rotor treatment zone 11 is still less than the preset range, the third control valve 56 is closed, and the high-temperature regeneration gas flowing out of the second outlet 44 of the heat recovery mechanism 40 directly enters the rotor regeneration zone 12. This allows the regeneration gas to avoid passing through the heating mechanism 30, thereby further saving energy. The high-temperature regeneration gas flowing out of the second outlet 44 of the heat recovery mechanism 40 directly into the rotor regeneration zone 12 has a relatively lower temperature than that flowing through the heating mechanism 30 and then into the rotor regeneration zone 12. This reduces the degree of dryness of the dehumidification rotor 10, thereby reducing the dehumidification rotor 10's ability to absorb moisture, thereby increasing the moisture content of the dry air flowing out of the rotor treatment zone 11. When the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the rotor treatment zone 11 is still less than a preset range, the temperature of the regeneration gas flowing out of the heating mechanism 30 can be further reduced by decreasing the opening of the fourth control valve 57 and adjusting the opening of the second control valve 55. By reducing the temperature and flow rate of the regeneration gas entering the rotor treatment zone 11, the degree of dryness of the dehumidification rotor 10 is reduced, thereby reducing the dehumidification rotor 10's ability to absorb moisture.

[0052] In some embodiments, reference Figure 1 As shown, the dehumidification equipment also includes a first air inlet duct 26, a second air inlet duct 27 and a control module 50; the first air inlet duct 26 and the second air inlet duct 27 are respectively connected to the regeneration duct inlet, the first air inlet duct 26 is used to introduce outdoor fresh air, and the second air inlet duct 27 is used to introduce equipment exhaust air of the air conditioning equipment; the control module 50 is respectively connected to the first air inlet duct 26 and the second air inlet duct 27, and the control module 50 is used to control the connection or disconnection of the first air inlet duct 26 and the second air inlet duct 27 respectively.

[0053] Furthermore, the air conditioning equipment is, for example, an air conditioner, a ventilation device, an air purification device, or the like, which is used to regulate air, fluidity, etc. The air conditioning equipment has equipment exhaust, and the equipment exhaust and the outdoor fresh air have different temperatures and humidities. The control module 50 of the embodiment of the present application controls the connection or disconnection of the first air inlet duct 26 and the second air inlet duct 27 respectively. The control module 50 can control the outdoor fresh air to enter the regeneration duct 22 through the first air inlet duct 26, and control the equipment exhaust to enter the regeneration duct 22 through the second air inlet duct 27, that is, to control the source of the regeneration gas (in the embodiment of the present application, the regeneration gas is the equipment exhaust and the outdoor fresh air) entering the regeneration duct 22, as well as the temperature and humidity of the regeneration gas.

[0054] The temperature and humidity of the regeneration gas entering the regeneration pipeline 22 affect the degree of drying of the regeneration gas in the rotor regeneration zone 12. Specifically, if the humidity of the regeneration gas is high, the regeneration gas will remove relatively less moisture from the dehumidification rotor 10, resulting in poor drying of the dehumidification rotor 10. High moisture content in the dehumidification rotor 10 results in poor drying of the treated air. If the humidity of the regeneration gas is low, the regeneration gas will remove relatively more moisture from the dehumidification rotor 10, resulting in better drying of the dehumidification rotor 10. Low moisture content in the dehumidification rotor 10 results in better drying of the treated air. When the temperature of the regeneration gas is high, the heating amplitude of the regeneration gas is relatively reduced; when the temperature of the regeneration gas is low, the heating amplitude of the regeneration gas is relatively increased. That is, by controlling the connection or disconnection of the first air inlet pipeline 26 and the second air inlet pipeline 27 through the control module 50, the embodiment of the present application can assist in adjusting the dehumidification capacity of the dehumidification equipment and correspondingly reduce energy consumption.

[0055] In some embodiments, the control module 50 further includes a fifth control valve 58 and a sixth control valve 59. The fifth control valve 58 is disposed in the first air inlet line 26 for controlling the opening of the first air inlet line 26; the sixth control valve 59 is disposed in the second air inlet line 27 for controlling the opening of the second air inlet line 27. In this embodiment of the present application, controlling the opening of the first air inlet line 26 by the fifth control valve 58 and controlling the opening of the second air inlet line 27 by the sixth control valve 59 have the advantages of simple and convenient structure and precise control.

[0056] In some embodiments, the control module 50 also includes a second moisture content detection unit, a third moisture content detection unit and a control unit 51; the second moisture content detection unit is arranged at the inlet of the first air inlet duct 26, for detecting the moisture content of the outdoor fresh air; the third moisture content detection unit is arranged at the inlet of the second air inlet duct 27, for detecting the moisture content of the exhaust air of the equipment; the control unit 51 is electrically connected to the second moisture content detection unit and the third moisture content detection unit respectively, and the control unit 51 adjusts the opening of the fifth control valve 58 and the sixth control valve 59 according to the moisture content detected by the second moisture content detection unit and the moisture content detected by the third moisture content detection unit.

[0057] In an embodiment of the present application, the control unit 51 adjusts the opening of the fifth control valve 58 and the sixth control valve 59 according to the moisture content detected by the second moisture content detection unit and the moisture content detected by the third moisture content detection unit, so as to control the proportion of outdoor fresh air entering the regeneration pipeline 22 through the first air inlet pipeline 26 and the proportion of equipment exhaust air entering the regeneration pipeline 22 through the second air inlet pipeline 27, that is, by controlling the temperature and humidity of the regenerated air entering the regeneration pipeline 22, the dehumidification capacity of the auxiliary adjustment dehumidification equipment is achieved, and the energy consumption is reduced accordingly.

[0058] It can be understood that the degree of valve opening refers to the degree to which the valve is open, i.e., any position between fully closed and fully open. For example, a fully closed valve does not allow any fluid to pass through. For example, a fully open valve allows gas to pass freely without obstruction. For example, a valve may be 20% open, and so on.

[0059] In a specific adjustment example, when the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the rotor treatment area 11 is greater than a preset range, the control unit 51 increases the ratio of the regeneration gas with a lower moisture content from the outdoor fresh air and the equipment exhaust air entering the regeneration pipeline 22 based on the moisture content detected by the second moisture content detection unit and the moisture content detected by the third moisture content detection unit, or selects the outdoor fresh air and the equipment exhaust air with a lower moisture content to be introduced into the regeneration pipeline 22, while the outdoor fresh air and the equipment exhaust air with a higher moisture content is not introduced into the regeneration pipeline 22. When the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the rotor treatment area 11 is within a preset range, the control unit 51 may increase the ratio of the regeneration gas with a higher temperature from the outdoor fresh air and the equipment exhaust air to be introduced into the regeneration pipeline 22, or selects the regeneration gas with a higher temperature from the outdoor fresh air and the equipment exhaust air to be introduced into the regeneration pipeline 22, thereby reducing the heating of the regeneration gas and reducing the energy consumption of the dehumidification equipment. When the first moisture content detection unit 61 detects that the moisture content of the dry air flowing out of the wheel processing area 11 is less than a preset range, the control unit 51 increases the ratio of the regeneration gas with high moisture content in the outdoor fresh air and the equipment exhaust air entering the regeneration pipeline 22, or selects the outdoor fresh air and the equipment exhaust air with high moisture content to be introduced into the regeneration pipeline 22, and the outdoor fresh air and the equipment exhaust air with low moisture content are not introduced into the regeneration pipeline 22.

[0060] In different regions, the temperature and humidity of equipment exhaust air and outdoor fresh air are also seasonally dependent. For example, in the summer, when temperatures are high and humidity is high, the outdoor fresh air is higher in temperature but higher in humidity. In other seasons, such as spring and autumn, the outdoor fresh air is lower in temperature but lower in humidity. For another example, in spring and autumn, air conditioning equipment usage is low, resulting in a lower exhaust flow rate. Alternatively, there is no exhaust air when the air conditioning equipment is not in use. Therefore, when the air conditioning equipment is in use, the control unit 51's adjustment of the opening of the fifth control valve 58 and the sixth control valve 59 is also seasonally dependent.

[0061] The control unit 51 controls the fifth control valve 58 and the sixth control valve 59 based on the moisture content detected by the second moisture content detection unit and the moisture content detected by the third moisture content detection unit. The control unit 51 should also be related to the control of the second control valve 55, the third control valve 56 and the fourth control valve 57. The control unit 51 uses comprehensive control to ensure that the dry air discharged by the dehumidification equipment meets the humidity requirements.

[0062] In some embodiments, the heat recovery mechanism 40 can be set according to the use requirements. For example, the heat recovery mechanism 40 is a plate-fin heat exchanger. A plate-fin heat exchanger is a highly efficient heat exchange device, which consists of a series of parallel metal plates. There are small gaps between each plate, and the gaps are filled with fins. The plate-fin heat exchanger maximizes the heat exchange area, thereby improving the heat transfer efficiency. The working principle of the plate-fin heat exchanger is based on heat conduction and heat convection. When two fluids of different temperatures (in the embodiment of the present application, the fluid is the rotor exhaust and the regeneration air) flow through the two sides of the plate-fin heat exchanger respectively, heat is transferred from the high-temperature fluid to the low-temperature fluid (that is, the heat of the rotor exhaust is transferred to the regeneration air), thereby realizing the exchange of heat energy. The use of plate-fin heat exchangers in dehumidification equipment has the advantage of high heat exchange efficiency.

[0063] In some embodiments, the first control valve 54, the second control valve 55, the third control valve 56, the fourth control valve 57, the fifth control valve 58 and the sixth control valve 59 are all set according to usage requirements. For example, the first control valve 54 is a switch valve; and / or, the second control valve 55 is a proportional control valve; and / or, the third control valve 56 is a proportional control valve; and / or, the fourth control valve 57 is a proportional control valve; and / or, the fifth control valve 58 is a switch valve, and / or, the sixth control valve 59 is a switch valve.

[0064] In the dehumidification device of the present embodiment, the control module 50 further includes a control unit 51, a detection unit 52, and a judgment unit 53. The detection unit 52 includes a first moisture content detection unit 61, a second moisture content detection unit, and a third moisture content detection unit. The detection unit 52 can detect the temperature and humidity at the air outlet of the rotor processing area 11 in real time, as well as the temperature and humidity of the outdoor fresh air and the exhaust air from the device. The judgment unit 53 is configured to determine the gear position based on a comparison of the temperature and humidity at the air outlet of the rotor processing area 11 with the target dry air moisture content d0. The control unit 51 can be used to adjust the various valves described above, as well as the gear position of the heating mechanism 30 and the gear position of the dehumidification device.

[0065] In some embodiments, taking the first control valve 54 as an on-off valve, the second control valve 55 as an on-off valve, the third control valve 56 as a proportional regulating valve, the fourth control valve 57 as a proportional regulating valve, and the fifth control valve 58 and the sixth control valve 59 as on-off valves as an example, the working process of the dehumidification device is as follows:

[0066] The dehumidification device has two modes, namely, fresh air mode and return air mode. The default mode is fresh air mode. In fresh air mode, outdoor fresh air enters the regeneration pipe 22 through the first air inlet pipe 26. In return air mode, the exhaust air of the air conditioning device enters the regeneration pipe 22 through the second air inlet pipe 27. The second moisture content detection unit is used to detect the moisture content of the outdoor fresh air, and the third moisture content detection unit is used to detect the moisture content of the equipment exhaust air. The control unit 51 calculates the enthalpy value of the outdoor fresh air and the enthalpy value of the equipment exhaust air (wherein enthalpy is the internal energy of air plus its flow work. In the embodiment of the present application, the enthalpy value includes sensible heat, i.e., heat caused by temperature change, and latent heat, i.e., heat caused by evaporation or condensation of water). The judgment unit 53 compares the enthalpy value of the outdoor fresh air and the enthalpy value of the equipment exhaust air and selects the smaller value to automatically enter the corresponding mode. In the fresh air mode, the fifth control valve 58 is opened and the sixth control valve 59 is closed; when switched to the return air mode, the fifth control valve 58 is closed and the sixth control valve 59 is opened.

[0067] Specific reference Figure 3 As shown, when the dehumidifier is started, i.e., turned on, it defaults to fresh air mode. After a certain period of time, the outdoor fresh air enthalpy value and the device exhaust air enthalpy value are obtained. The judgment unit 53 compares the outdoor fresh air enthalpy value and the device exhaust air enthalpy value and selects the smaller value to automatically enter the corresponding mode, such as maintaining the fresh air mode or entering the return air mode. After continuing to operate for a time t0, the outdoor fresh air enthalpy value and the device exhaust air enthalpy value are obtained again. The judgment unit 53 again compares the outdoor fresh air enthalpy value and the device exhaust air enthalpy value and selects the smaller value to automatically enter the corresponding mode. This process repeats until the dehumidifier is shut down.

[0068] Reference Figure 4As shown, the dehumidification device is started, the target dry air humidity d is set (the target dry air humidity d can also be the set value when the dehumidification device was last used), the first control valve 54 is opened, the second control valve 55, the third control valve 56 and the fourth control valve 57 are closed, the fifth control valve 58 and the sixth control valve 59 are opened or closed according to the corresponding mode, and the heating mechanism 30 is turned on. The dehumidification device is turned on for a first preset time, for example, 5 minutes, and then the temperature T1 and humidity Th1 of the dry air discharged from the rotor treatment area 11 are detected in real time, and the real-time outlet humidity d1 of the dry air discharged from the rotor treatment area 11 is calculated. d1 is compared with d. If the temperature T1-X| is less than d for a second preset time, for example, 10 seconds, the heating mechanism 30 is turned off, the fourth control valve 57 is opened (opened to the minimum opening), the first control valve 54 is closed, the second control valve 55 is opened, and the third control valve 56 remains closed. At the same time, the temperature T1 and humidity Th1 of the dry air discharged from the rotor processing area 11 are continuously monitored in real time, and the moisture content d1 of the output air is calculated. If |d1-X|>d, the opening of the fourth control valve 57 is increased. If the fourth control valve 57 is opened to its maximum opening and |d1-X|>d is still present, the second control valve 55 remains open, the third control valve 56 is increased, the first control valve 54 remains closed, and the heating mechanism 30 is opened to the minimum heating gear, such as the first gear of electric heating. If |d1-X|>d is still present after the third control valve 56 is opened to its maximum, the second control valve 55 is closed, and the heating mechanism 30 is opened and increased in gears step by step as an auxiliary electric heater to adjust the moisture content of the output air.

[0069] After the dehumidification device is turned on for a first preset time, if |d1-X|>d continues for a third preset time (e.g., 10 seconds) and |d1-X|>d, the fourth control valve 57 is opened and adjusted to the maximum opening, the second control valve 55 is opened, and the heating mechanism 30 is turned to the minimum gear. At the same time, the temperature T1 and humidity Th1 of the dry air discharged from the rotor treatment area 11 are continuously detected in real time and the air humidity d1 is calculated. If |d1-X|>d is still found, the third control valve 56 is opened and increased, and the first control valve 54 is closed. After the third control valve 56 is opened to the maximum, if |d1-X|>d is still found, the second control valve 55 is closed. The third control valve 56 is automatically adjusted (PID control) based on the humidity d0 and humidity d1. If |d1-X|≤d is found, the third control valve 56 is closed, the second control valve 55 is opened, the first control valve 54 remains closed, and the fourth control valve 57 is PID-controlled based on the humidity d0 and humidity d1.

[0070] Here, X is the moisture content tolerance, and d±X represents the two endpoints of the preset moisture content range. This control of the dehumidifier can be integrated into the remote access and control capabilities of the building management system (BMS remote control) for intelligent and precise control.

[0071] In the dehumidification device of the present embodiment, when the dehumidification rotor 10 is operating, the rotor exhaust air from the rotor regeneration zone 12 is high-temperature exhaust air. This high-temperature exhaust air can be recovered through the heat recovery mechanism 40 for heat recovery. This heat is then used to heat the regeneration air in the rotor regeneration zone 12, raising the temperature of the regeneration air and thereby reducing the heating load of the heating mechanism 30. Furthermore, by PID adjustment of the ratio of regeneration air and high-temperature exhaust air entering the heating mechanism 30 based on the moisture content d0 and the moisture content d1, the original heat source for the regeneration air, which was primarily heated by the heating mechanism 30, is changed to auxiliary electric heating by the heating mechanism 30. This significantly reduces the energy consumption of heating the regeneration air to the desired temperature. This effectively utilizes the heat energy of the rotor exhaust air, reduces the energy consumption of the dehumidification device, and achieves energy conservation.
