[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figures 1 to 23 As shown, the first embodiment of the present invention provides a first multi-stage rotary dehumidification device, comprising: At least three wheels 100, a gap is formed between two adjacent wheels 100, the axes of the at least three wheels 100 are coaxially arranged, the gap located on the first side of the axis forms a working air channel, the gap located on the second side of the axis forms a regeneration air channel, and the first side of the axis and the second side of the axis are arranged opposite to each other; The heat exchanger 102 is arranged in the working air channel; A regeneration air valve 104 is provided in the regeneration air channel between at least one pair of adjacent rotors 100, and is used to switch the regeneration air channel and the rotor 100 on and off; The regeneration air switching component 106 is fluidly connected to the regeneration air channel to switch outdoor fresh air and / or working air as the regeneration air.

[0029] According to the multi-stage rotary dehumidification device provided in the embodiment of the first aspect of the present invention, an effective multi-stage dehumidification structure is formed by setting at least three rotary wheels 100 and setting their axes coaxially. Each stage of the rotary wheel 100 can dehumidify the air to a certain extent, thereby improving the overall dehumidification efficiency. The setting of the regeneration air valve 104 allows the on-off of the regeneration air channel to be switched when necessary, which helps to confirm whether one regeneration air serves multiple rotary wheels 100 according to actual needs to improve the energy efficiency of the dehumidification process. The regeneration air switching component 106 can switch outdoor fresh air and / or working air as regeneration air, which provides users with greater flexibility. When the outdoor air humidity is low, you can choose to use outdoor fresh air for regeneration to reduce energy consumption; when the outdoor air humidity is high, you can choose to use working air for regeneration to ensure the dehumidification effect. The setting of the regeneration air bypass valve 108 allows the fluid connection and disconnection between the regeneration air and the rotor 100 to be controlled when necessary, which helps when one regeneration air serves multiple rotors 100, the regeneration air can be controlled to bypass the rotor 100 that does not need to work, reduce wind resistance, and improve the energy efficiency of the dehumidification process. The setting of the working air bypass valve 110 allows the fluid connection and disconnection between the working air and the rotor 100 and the heat exchanger 102 to be controlled when necessary, which helps to control the working air to bypass the rotor 100 that does not need to work, reduce wind resistance, and improve the energy efficiency of the dehumidification process. The setting of the heat exchanger 102 helps to heat exchange the air in the working air channel. The heat exchanger 102 can be attached to at least one rotor 100, thereby further adjusting the temperature and humidity of the air and improving the controllability of the dehumidification process. The outdoor fresh air can be heated and / or cooled and / or filtered before entering the regeneration air channel. By arranging the axes of at least three rotors 100 coaxially and forming intervals between adjacent rotors 100 to form a working air channel and a regeneration air channel, the device of the present invention is more compact in structure and effectively utilizes space. This compact structure not only reduces the floor space, but also facilitates the installation and maintenance of the equipment. The multi-stage rotor dehumidification device of the present invention is reasonably designed in structure, and the connections between the various components are tight and reliable, ensuring the stable operation of the equipment. At the same time, by accurately controlling the switches of the regeneration air valve 104 and the regeneration air switching assembly 106, precise regulation of the dehumidification process can be achieved, further improving the reliability of the equipment.

[0030] Understandably, Figures 1 to 23 It shows different operating states of the first rotary dehumidifier provided by the embodiment of the present invention. For example, the regeneration air switching component 106 can switch different regeneration air sources. When the regeneration air valves 104 at different positions are in different working states, they can correspond to different operating states of the first rotary dehumidifier provided by the embodiment of the present invention.

[0031] Please continue to see Figure 24 to Figure 26 The first aspect of the present invention provides a second multi-stage rotary dehumidification device, and the specific technical solution is as follows: The multi-stage rotary dehumidification device further includes a regeneration air bypass valve 108 .

[0032] Setting of regeneration air bypass valve 108: The regeneration air bypass valve 108 is disposed in the regeneration air passage.

[0033] The design of the valve allows the control of the fluid connection between the regeneration air and the wheel 100 when necessary. This helps when one regeneration air serves multiple wheels 100. The regeneration air can be controlled to bypass the wheels 100 that do not need to work, thereby reducing wind resistance and improving the energy efficiency of the dehumidification process.

[0034] Control of regeneration air bypass valve 108: The regeneration air bypass valve 108 can be remotely or locally controlled by a control system.

[0035] According to actual operation requirements, such as the dehumidification efficiency of the wheel 100, the air volume of the regeneration air, outdoor climate conditions, etc., the control system can send a signal to the regeneration air bypass valve 108 to open or close the bypass channel.

[0036] According to one embodiment of the present invention, it also includes a regeneration air bypass channel, which is arranged in the regeneration air channel. The regeneration air bypass valve 108 is arranged between the regeneration air channel and the regeneration air bypass channel. The regeneration air bypass valve 108 is used to control the fluid connection between the regeneration air channel and the regeneration air bypass channel.

[0037] According to a specific embodiment of the present invention, a regeneration air bypass channel and a corresponding regeneration air bypass valve 108 are further provided in the multi-stage rotary dehumidification device on the original basis.

[0038] Setting of regeneration air bypass channel: The regeneration air bypass channel is carefully designed and arranged in the regeneration air channel to form a bypass parallel to the main regeneration air path.

[0039] This bypass allows the regeneration air to bypass the rotor 100 and flow directly under certain conditions without passing through the dehumidification process of the rotor 100.

[0040] Installation and function of regeneration air bypass valve 108: The regeneration air bypass valve 108 is installed at the connection between the regeneration air channel and the regeneration air bypass channel to control the flow of fluid.

[0041] The valve has high reliability and flexibility and can be opened or closed quickly and accurately according to the instructions of the control system.

[0042] When the control system sends an opening signal, the regeneration air bypass valve 108 will open, allowing the regeneration air to flow through the bypass channel; when the control system sends a closing signal, the regeneration air bypass valve 108 will close, and the regeneration air will pass through the wheel 100 normally for dehumidification.

[0043] Integration of control systems: The regeneration air bypass valve 108 is tightly integrated with the control system of the multi-stage rotary dehumidification device to ensure accurate control according to actual needs and environmental conditions.

[0044] The control system can intelligently decide when to open or close the regeneration air bypass valve 108 based on factors such as the dehumidification efficiency of the wheel 100, the air volume of the regeneration air, outdoor climate conditions, and the dehumidification target set by the user.

[0045] The addition of the regeneration air bypass channel and the regeneration air bypass valve 108 enables the multi-stage rotary dehumidification device to flexibly adjust the processing method of the regeneration air according to actual needs and environmental conditions.

[0046] In summary, by adding the regeneration wind bypass channel and the regeneration wind bypass valve 108, the multi-stage rotary dehumidification device of the present invention has been significantly improved in terms of flexibility, dehumidification effect, energy saving and consumption reduction, equipment life and user experience. This innovative design enables the system to better adapt to different operating conditions and requirements, providing users with a more efficient, reliable and economical dehumidification solution.

[0047] Understandably, Figure 24 to Figure 26 It shows different operating states of the second rotary dehumidifier provided by the embodiment of the present invention. For example, the regeneration air switching component 106 can switch different regeneration air sources. When the regeneration air bypass valve 108 at different positions is in different working states, they can correspond to different operating states of the second rotary dehumidifier provided by the embodiment of the present invention.

[0048] Please continue to see Figures 27 to 34 The first aspect of the present invention provides a third multi-stage rotary dehumidification device, and the specific technical solution is as follows: According to a specific embodiment of the present invention, a working air bypass valve 110 is further provided on the original basis of the multi-stage rotary dehumidification device.

[0049] Installation and function of working air bypass valve 110: The working air bypass valve 110 is cleverly installed in the working air channel of the multi-stage rotary dehumidification device, and is located on the path before the working air enters the rotary wheel 100 and the heat exchanger 102 .

[0050] The main function of the valve is to control the flow of fluid between the working air and the rotor 100 and the heat exchanger 102. When the valve is open, the working air can bypass the rotor 100 and the heat exchanger 102 and flow directly; when the valve is closed, the working air will pass through the rotor 100 for dehumidification and the heat exchanger 102 for heat exchange.

[0051] Control of working air bypass valve 110: The working air bypass valve 110 is tightly integrated with the control system of the multi-stage rotary dehumidification device and can be switched on and off by remote or local control.

[0052] The control system can intelligently decide when to open or close the working air bypass valve 110 according to actual operating requirements, such as the humidity and temperature of the working air and the status of the wheel 100 and the heat exchanger 102.

[0053] Overall coordination of the system: The addition of the working air bypass valve 110 does not destroy the overall coordination of the multi-stage rotary dehumidification device. On the contrary, it enables the system to more flexibly adjust the processing method of the working air according to actual needs.

[0054] When the humidity of the working air is low or the rotor 100 and the heat exchanger 102 are in a saturated state, opening the working air bypass valve 110 can avoid unnecessary energy consumption and wear while maintaining stable operation of the system.

[0055] The addition of the working air bypass valve 110 enables the multi-stage rotary dehumidification device to flexibly adjust the working air processing method according to actual needs and environmental conditions. By reasonably controlling the opening and closing of the working air bypass valve 110, unnecessary energy consumption can be reduced.

[0056] According to one embodiment of the present invention, the working air bypass valve 110 is disposed in the working air channel.

[0057] According to a specific embodiment of the present invention, the multi-stage rotary dehumidification device is further optimized, in particular, a working air bypass valve 110 is added in the working air channel.

[0058] Installation position of working air bypass valve 110: The working air bypass valve 110 is precisely installed in the working air channel of the multi-stage rotary dehumidification device, and is located on the path before the working air enters the rotary wheel 100 .

[0059] The position design of the valve ensures that when necessary, the working air can be quickly and effectively bypassed around the wheel 100 and the heat exchanger 102 without undergoing dehumidification and heat exchange processing.

[0060] The structure and function of the working air bypass valve 110: The working air bypass valve 110 adopts high-quality materials and advanced manufacturing technology to ensure its stability and reliability in long-term operation.

[0061] The valve has two states, open and closed, and can be controlled remotely or locally through the control system.

[0062] When the control system sends an open signal, the working air bypass valve 110 will open, allowing the working air to flow directly through the bypass channel; when the control system sends a close signal, the working air bypass valve 110 will close, and the working air will normally pass through the wheel 100 for dehumidification and perform heat exchange through the heat exchanger 102.

[0063] Integration of control systems: The working air bypass valve 110 is tightly integrated with the control system of the multi-stage rotary dehumidification device, ensuring accurate control according to actual needs and environmental conditions.

[0064] The control system can intelligently decide when to open or close the working air bypass valve 110 based on factors such as the humidity and temperature of the working air, the dehumidification efficiency of the wheel 100, the heat exchange efficiency of the heat exchanger 102, and the dehumidification target set by the user.

[0065] According to one embodiment of the present invention, it also includes a working air bypass channel, which is arranged in the working air channel. The working air bypass valve 110 is arranged between the working air channel and the working air bypass channel. The working air bypass valve 110 is used to control the fluid connection between the working air channel and the working air bypass channel.

[0066] According to a specific embodiment of the present invention, the multi-stage rotary dehumidification device is further optimized on the original basis, and a working air bypass channel and a corresponding working air bypass valve 110 are added.

[0067] Setting of working air bypass channel: The working air bypass channel is carefully designed and arranged in the working air channel of the multi-stage rotary dehumidification device, forming a bypass parallel to the main working air path.

[0068] This bypass allows the working air to bypass the rotor 100 and the heat exchanger 102 and flow directly under certain conditions without going through the dehumidification and heat exchange processes.

[0069] Installation and function of working air bypass valve 110: The working air bypass valve 110 is installed at the connection between the working air channel and the working air bypass channel to control the flow of fluid.

[0070] The valve has high reliability and flexibility and can be opened or closed quickly and accurately according to the instructions of the control system.

[0071] When the control system sends an open signal, the working air bypass valve 110 will open, allowing the working air to flow through the bypass channel; when the control system sends a close signal, the working air bypass valve 110 will close, and the working air will normally pass through the wheel 100 for dehumidification and perform heat exchange through the heat exchanger 102.

[0072] Integration of control systems: The working air bypass valve 110 is tightly integrated with the control system of the multi-stage rotary dehumidification device, ensuring accurate control according to actual needs and environmental conditions.

[0073] The control system can intelligently decide when to open or close the working air bypass valve 110 based on factors such as the humidity and temperature of the working air, the dehumidification efficiency of the wheel 100, the heat exchange efficiency of the heat exchanger 102, outdoor climate conditions, and the dehumidification target set by the user.

[0074] Overall coordination of the system: The addition of the working air bypass channel and the working air bypass valve 110 does not destroy the overall coordination of the multi-stage rotary dehumidification device. On the contrary, they enable the system to more flexibly adjust the processing method of the working air according to actual needs.

[0075] When the working air humidity is low, the wheel 100 and the heat exchanger 102 are in a saturated state, or the outdoor climate conditions are suitable, opening the working air bypass valve 110 can avoid unnecessary dehumidification and heat exchange processing while maintaining stable operation of the system.

[0076] The addition of the working air bypass channel and the working air bypass valve 110 enables the multi-stage rotary dehumidifier to flexibly adjust the working air processing method according to actual needs and environmental conditions. By reasonably controlling the opening and closing of the working air bypass valve 110, unnecessary dehumidification and heat exchange processing can be reduced, thereby reducing the energy consumption of the system. This helps to reduce operating costs and improve the economic benefits of the system.

[0077] Understandably, Figures 27 to 34 It shows different operating states of the third rotary dehumidifier provided by the embodiment of the present invention. For example, when the working air bypass valve 110 at different positions is in different working states, they can correspond to different operating states of the third rotary dehumidifier provided by the embodiment of the present invention.

[0078] Please continue to see Fig.35 The first aspect of the present invention provides a fourth multi-stage rotary dehumidification device, and the specific technical solution is as follows: According to a specific embodiment of the present invention, the multi-stage rotary dehumidification device is further optimized on the original basis, and a regeneration air bypass valve 108 and a working air bypass valve 110 are added. These two valves are used to control the fluid connection and disconnection between the regeneration air and the working air and the rotary wheel 100, thereby improving the flexibility and operation efficiency of the system.

[0079] Setting and function of regeneration air bypass valve 108: The regeneration air bypass valve 108 is installed at the connection between the regeneration air channel and the rotor 100, and is used to control whether the regeneration air flows through the rotor 100 for regeneration processing.

[0080] When the control system sends an opening signal, the regeneration wind bypass valve 108 will open, allowing the regeneration wind to bypass the rotor 100 and flow directly; when the control system sends a closing signal, the regeneration wind bypass valve 108 will close, and the regeneration wind will pass through the rotor 100 normally for regeneration processing.

[0081] The addition of the regeneration air bypass valve 108 enables the system to flexibly adjust the processing method of the regeneration air according to the demand for regeneration air and the regeneration efficiency of the rotor 100, thereby improving the regeneration efficiency and energy utilization efficiency.

[0082] Setting and function of working air bypass valve 110: The working air bypass valve 110 is installed at the connection between the working air channel and the rotor 100, and is used to control whether the working air flows through the rotor 100 for dehumidification processing.

[0083] When the control system sends an open signal, the working air bypass valve 110 will open, allowing the working air to bypass the wheel 100 and flow directly; when the control system sends a close signal, the working air bypass valve 110 will close, and the working air will pass through the wheel 100 normally for dehumidification.

[0084] The addition of the working air bypass valve 110 enables the system to flexibly adjust the working air processing method according to the working air demand and the dehumidification efficiency of the wheel 100, thereby improving the dehumidification efficiency and energy utilization efficiency.

[0087] The addition of the regeneration air bypass valve 108 and the working air bypass valve 110 enables the multi-stage rotary dehumidifier to flexibly adjust the processing methods of the regeneration air and the working air according to actual needs and environmental conditions. This helps the system to better adapt to different operating scenarios and needs and improve the overall dehumidification and regeneration efficiency. By reasonably controlling the opening and closing of the regeneration air bypass valve 108 and the working air bypass valve 110, unnecessary regeneration and dehumidification processing can be reduced, thereby reducing the energy consumption of the system. This helps to reduce operating costs and improve the economic benefits of the system.

[0088] In addition to the four multi-stage rotary dehumidification devices provided in the first aspect of the present invention, the present invention further includes: According to one embodiment of the present invention, the heat exchanger 102 is attached to at least one rotating wheel 100 .

[0089] According to a specific embodiment of the present invention, an innovative heat exchange system is proposed, in which the heat exchanger 102 is closely fitted with at least one rotating wheel 100.

[0090] Fitting design of heat exchanger 102 and rotor 100: The heat exchanger 102 is designed to fit closely with at least one rotating wheel 100 to form an integrated heat exchange unit.

[0091] The bonding method can be direct contact, that is, the heat exchange surface of the heat exchanger 102 is in direct contact with the surface of the wheel 100, or indirect contact, where heat transfer is achieved through a thin layer of heat conduction medium (such as heat conducting oil, heat conducting glue, etc.).

[0092] The fitted design ensures efficient heat transfer between the rotor 100 and the heat exchanger 102, reduces heat loss, and improves the overall heat exchange efficiency of the system.

[0093] According to an embodiment of the present invention, the outdoor fresh air is subjected to air processing steps such as heating and / or cooling and / or filtering before entering the regeneration air channel, which further increases the diversity of the regeneration air intake state.
