Description

Technical Field

[0001] This invention relates to the field of high-efficiency dehumidification devices, specifically a heat pump type high-efficiency dehumidification device with waste heat recovery. Background Technology

[0002] In environments requiring air temperature and humidity regulation, existing technologies mostly focus on temperature and humidity control, such as common condensing dehumidification air conditioning systems, which generally use a unified low-temperature cold source to simultaneously process sensible and latent heat loads. However, when dealing with different environmental needs, they have revealed many shortcomings: on the one hand, in high humidity environments, their dehumidification efficiency is poor. Traditional equipment often lacks an efficient staged dehumidification mechanism, making it difficult to effectively process high-temperature and humid air and quickly reduce air humidity to the ideal level, resulting in a long-term humid indoor environment, which not only affects human comfort but may also damage indoor items. On the other hand, energy waste is a prominent issue. Existing technologies rarely achieve comprehensive recovery and utilization of waste heat. A large amount of waste heat generated during air handling, such as the adsorption heat generated by the dehumidifying rotor and the heat dissipated during equipment operation, is mostly directly emitted into the environment without effective conversion. At the same time, the equipment consumes a large amount of electricity during operation, but energy consumption cannot be reduced through waste heat utilization, resulting in low energy utilization and high operating costs, which is inconsistent with the current development trend of energy conservation and environmental protection.

[0003] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a heat pump-type high-efficiency dehumidification device with waste heat recovery to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat pump type high-efficiency dehumidification device with waste heat recovery, comprising a dehumidification base, a heat-locking cavity disposed at the center of the dehumidification base, a first heat-pressing dehumidification box and a second heat-pressing dehumidification box symmetrically disposed at both ends of the heat-locking cavity, a heat pump storage box disposed side by side at one end of the first heat-pressing dehumidification box, a flow-guiding center frame disposed at the center of the second heat-pressing dehumidification box, and irregularly shaped pressure plates and mesh frames symmetrically disposed at the top and bottom of the flow-guiding center frame; A heat collection box cover is located at the top center of the heat-locking chamber and is snapped between the first and second hot-press dehumidification boxes. A water injection frame is located below the heat collection box cover. An impeller heat exchanger connected to the first and second hot-press dehumidification boxes is located at the top center of the water injection frame. A central shaft is sleeved through the middle of both sides of the impeller heat exchanger. A heat exchange shaft frame is sleeved on the shaft. Several sets of heat exchange arc plates are arranged in a ring array on the outer periphery of the heat exchange shaft frame. Hemispherical radiators are symmetrically arranged on the outer walls of both sides of the impeller heat exchanger.

[0006] Furthermore, the dehumidification base is provided with medium inlets at both ends for connecting the heat pump storage box, the first hot-press dehumidification box, and the second hot-press dehumidification box. Hot drain valves are symmetrically arranged at the four corners of the bottom wall of the temperature lock chamber, and branch pipes are provided at the top of the hot drain valves for connecting to the bottom of the first hot-press dehumidification box and the second hot-press dehumidification box.

[0007] Furthermore, a sealing cover plate connected to the top of the second hot-press dehumidification chamber is sleeved on the top of the chamber and connected to the top of the flow guide center frame. An upper locking cover is provided on the top of the sealing cover plate. A back pressure cylinder connected to the irregular pressure plate is installed through the center of the flow guide center frame. Auxiliary cylinders that cooperate with the back pressure cylinder are symmetrically arranged at the four corners of the inner wall of the second hot-press dehumidification chamber.

[0008] Furthermore, several sets of staggered side plates are symmetrically arranged on both sides of the flow guiding center frame. The side plates and the second hot-press dehumidification box are filled with water-absorbing sponges. The mesh frame is located at the bottom of the side plates, and a buffer water storage tank is provided between the bottom of the mesh frame and the bottom wall of the second hot-press dehumidification box.

[0009] Furthermore, the impeller heat exchanger is provided with external connecting pipes at both ends that are sleeved with the first and second hot-press dehumidification chambers. An impeller blade assembly is sleeved in the center of the impeller heat exchanger. The central shaft is sleeved with the impeller blade assembly for transmission. The hemispherical radiator is provided with a medium flow channel with an annular arrangement structure. The medium flow channel is provided with a channel opening that penetrates the interior of the impeller heat exchanger and is respectively connected to the two sets of external connecting pipes.

[0010] Furthermore, the water injection frame is symmetrically provided with overflow frames near the impeller heat exchanger at both ends, and hemispherical spray frames are provided on both sides of the water injection frame above the overflow frames. The hemispherical spray frames are sleeved on the outer wall of the hemispherical radiator, and several sets of spray valves facing the hemispherical radiator are provided on the inner wall of the hemispherical spray frames.

[0011] Furthermore, a number of supporting paddle shafts are arranged in a ring array on the outer peripheral wall of the heat exchange shaft frame. The top support rod of the supporting paddle shaft is connected to the inner wall of the heat exchange arc plate at multiple points. A water injection slip ring valve is sleeved on the middle of the outer side of the heat exchange shaft frame, and an external water pipe is provided on the outside of the water injection slip ring valve.

[0012] Furthermore, metal pillars are respectively provided at the bottom center and one side edge of the heat collection box cover, and several sets of connecting valves are provided on the surface of the metal pillars. Spiral heat exchange tubes are provided between the metal pillars. Several sets of tube racks connected to the spiral heat exchange tubes are provided on the bottom surface of the heat collection box cover, and several sets of water spray holes are provided on the bottom surface of the heat collection box cover.

[0013] The beneficial effects of this invention are: 1. This invention employs a graded treatment mode of high-temperature preliminary dehumidification followed by low-temperature secondary dehumidification. Combined with a heat pump drive and a tortuous flow channel design, it can efficiently extract high-temperature and humid air from the environment. The air undergoes preliminary dehumidification through the dispersion and impact of corrosion-resistant metal blocks and contact with absorbent sponges within the second heat-press dehumidification chamber. After being cooled by an impeller heat exchanger, the air is then subjected to secondary dehumidification by the first heat-press dehumidification chamber. This significantly improves dehumidification efficiency and ensures that the air ultimately delivered to the environment meets the requirements for constant temperature and low humidity, making it precisely suitable for scenarios with strict requirements for air temperature and humidity.

[0014] 2. This invention innovatively uses a flow-guiding central frame to divide symmetrical chambers. With the coordinated operation of the back pressure cylinder, auxiliary cylinder and gate valve, while the water-absorbing sponge is pressing down to filter water in one side chamber, the other side chamber can continuously deliver high-temperature humid air, realizing the simultaneous dehumidification and dehydration. This avoids the interruption of temperature control and dehumidification caused by the device being shut down for maintenance, and ensures the continuous moisture absorption capacity of the water-absorbing sponge, effectively maintaining the long-term stable operating efficiency of the device.

[0015] 3. This invention constructs a complete waste heat utilization system around heat recovery and cold water utilization, realizing the efficient conversion of energy and water resources: On the one hand, external pure cold water is introduced through the water injection frame, and part of it is sprayed on the outside of the hemispherical radiator through the hemispherical spray frame. Combined with the internal circulating cold water of the heat exchange arc and the stirring action of the supporting paddle shaft, the heat of the hemispherical radiator is quickly absorbed, and the cold water is converted into pure hot water; on the other hand, the waste heat of each component collected in the heat lock chamber is further recovered through the low-speed cold water flow and water mist spray of the spiral heat exchange tube, which not only reduces the impact of internal heat dissipation on the environment, but also maximizes the utilization of waste heat resources.

[0016] 4. This invention uses a device to guide pure hot water and dehydrated wastewater separately through a dual-pipe hot water drain valve, and with the water level control of the overflow rack, it realizes the orderly recycling of hot water and centralized treatment of wastewater. While improving the dehumidification and temperature control performance, it reduces energy waste and water consumption, and is both environmentally friendly and economical.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Figure 12As shown, this embodiment is a heat pump type high-efficiency dehumidification device with waste heat recovery, including a dehumidification base 1, a temperature lock chamber 101 is arranged in the center of the dehumidification base 1, a first hot press dehumidification box 3 and a second hot press dehumidification box 5 are symmetrically arranged at both ends of the temperature lock chamber 101, a heat pump storage box 2 is arranged side by side on the end face of the first hot press dehumidification box 3, a flow guide center frame 501 is arranged in the center of the second hot press dehumidification box 5, and irregularly shaped pressure plates 504 and mesh frames 506 are symmetrically arranged at the top and bottom of the flow guide center frame 501; Depending on the installation environment, the device is connected to the medium inlet via an external pipe. The high-power heat pump inside the heat pump storage tank 2 operates, drawing out high-temperature, high-humidity air from the environment through the medium inlet and external pipe at one end. This air is labeled as high-temperature, humid air and then passes through the heat exchange and dehumidification process of the heat pump-type high-efficiency dehumidification device to obtain standard air. At the other end, through the medium inlet and external pipe, the standard air is pushed to the usage environment area, ensuring that the usage environment maintains the required constant temperature and low humidity.

[0022] The dehumidification base 1 has medium inlets that connect the heat pump storage box 2, the first hot-press dehumidification box 3, and the second hot-press dehumidification box 5 through both ends. The bottom wall of the temperature lock chamber 101 is symmetrically provided with hot drain valves 102 at the four corners. The top of the hot drain valves 102 is provided with branch pipes that connect to the bottom of the first hot-press dehumidification box 3 and the second hot-press dehumidification box 5.

[0023] The high-temperature and humid air drawn from the outside initially enters the interior of the second thermostatic dehumidifier 5. The corrosion-resistant metal block set by the flow guide center frame 501 towards the medium inlet area directly impacts the drawn high-temperature and humid air, causing it to disperse and flow into the interior of the thermostatic dehumidifier. The high-temperature and humid air flows in a tortuous manner along the flow chamber constructed between the side plate 505, the flow guide center frame 501 and the body of the second thermostatic dehumidifier 5, so that the high-temperature and humid air can fully contact the filling water-absorbing sponge, thereby achieving the initial dehumidification treatment of the high-temperature and humid air at the high-temperature stage.

[0024] After the high-temperature and humid air is cooled by the impeller heat exchanger 7, it passes through the hot-press dehumidification chamber 3, where the water-absorbing sponge inside the hot-press dehumidification chamber 3 performs secondary dehumidification on the high-temperature and humid air at a low temperature.

[0025] The top of the second heat-press dehumidification chamber 5 is fitted with a sealing cover 503 that is connected to the top of the flow guide center frame 501. The top of the sealing cover 503 is provided with an upper locking cover 502. The flow guide center frame 501 is internally connected to the center of the center and is connected to the irregular pressure plate 504. The inner walls of the second heat-press dehumidification chamber 5 are symmetrically provided with auxiliary cylinders that cooperate with the return pressure cylinder 507.

[0026] The interior of the first and second hot-press dehumidification chambers 3 and 5 is divided into two symmetrical chambers by a central guide frame 501. Based on the need to process high-temperature, humid air, the absorbent sponges in one side of the chamber are pressurized for filtration. Under the coordinated operation of the back pressure cylinder 507 and the auxiliary cylinder on the same side, the shaped pressure plate 504 on that side is pressed down towards the mesh frame 506, causing the absorbent sponges to be squeezed and dehydrated. The detached water collects along the mesh frame 506 in a buffer storage tank, which is periodically cleaned by the hot drain valve 102. During the dehydration process, the gate valves installed on the inner walls of the first and second hot-press dehumidification chambers 3 and 5 towards the heat pump storage tank 2 are activated. These gate valves are fitted into the inner walls of both chambers. Based on the dehydration requirements, one side of the chamber is closed in one direction, while the extracted high-temperature, humid air flows pressurized along the other side of the chamber. This ensures both continuous operation of the device and internal dehydration, maintaining the efficiency and effectiveness of subsequent dehumidification.

[0027] The flow guide center frame 501 has several sets of staggered side plates 505 symmetrically arranged on both sides. The side plates 505 and the second heat-press dehumidification box 5 are filled with water-absorbing sponges. The mesh frame 506 is located at the bottom of the side plates 505, and a buffer water storage tank is set between the bottom of the mesh frame 506 and the bottom wall of the second heat-press dehumidification box 5.

[0028] After initial high-temperature dehumidification treatment in the hot-press dehumidification chamber 25, high-temperature and low-humidity air is obtained. It is connected to the hot-press dehumidification chamber 25 through the external connecting pipe 701, and the high-temperature and low-humidity air is diverted into the impeller heat exchanger 7. The impeller heat exchanger 7 is provided with a main channel, and the impeller blade assembly 704 is sleeved in the main channel. With the help of the high-efficiency heat pump, the high-temperature and low-humidity air is drawn in pressure, which causes the impeller blade assembly 704 to be pushed and rotated in the narrow space inside the main channel. The impeller blade assembly 704 drives the heat exchange shaft frame 8 to rotate through the central shaft 703.

[0029] Example 2: A heat collection box cover 4 is located at the top center of the heat-locking chamber 101 and is snapped between the first heat-pressing dehumidification box 3 and the second heat-pressing dehumidification box 5. A water injection frame 6 is located below the heat collection box cover 4. An impeller heat exchanger 7 connected to the first heat-pressing dehumidification box 3 and the second heat-pressing dehumidification box 5 is located at the top center of the water injection frame 6. A central shaft 703 is sleeved through the middle of both sides of the impeller heat exchanger 7. A heat exchange shaft frame 8 is sleeved on the shaft of the central shaft 703. Several sets of heat exchange arc plates 803 are arranged in a ring array on the outer periphery of the heat exchange shaft frame 8. Hemispherical radiators 702 are symmetrically arranged on the outer walls of both sides of the impeller heat exchanger 7.

[0030] The channel opening near the external connecting pipe 701 is connected to the medium flow channel. Due to the obstruction of the rotation efficiency of the impeller assembly 704 in the main channel, some high-temperature and low-humidity air is forced to flow into the interior of the hemispherical radiator 702 and eventually gather in the area of ​​the external connecting pipe 701 near the end of the hot-press dehumidification box 3. The high-temperature and low-humidity air entering the interior of the hemispherical radiator 702 is affected by the width of the hemispherical radiator 702 body and the medium flow channel, which causes the high-temperature heat in this part of the high-temperature and low-humidity air to be transferred to the hemispherical radiator 702 body, causing the heat in the high-temperature and low-humidity air to be rapidly replaced, resulting in low-temperature and low-humidity air.

[0031] The impeller heat exchanger 7 has external connecting pipes 701 at both ends that are sleeved with the first hot-press dehumidification box 3 and the second hot-press dehumidification box 5. The impeller blade assembly 704 is sleeved in the center of the impeller heat exchanger 7. The central shaft 703 is sleeved with the impeller blade assembly 704 for transmission. The hemispherical radiator 702 has a medium flow channel with an annular arrangement structure inside. The medium flow channel has a channel opening that penetrates the interior of the impeller heat exchanger 7 and is respectively connected to the two sets of external connecting pipes 701.

[0032] The water inlet frame 6 has overflow frames 601 symmetrically arranged at both ends near the impeller heat exchanger 7. The water inlet frame 6 has hemispherical spray frames 602 located above the overflow frames 601 on both sides. The hemispherical spray frames 602 are sleeved on the outer wall of the hemispherical radiator 702. The inner wall of the hemispherical spray frames 602 is provided with several sets of spray valves 603 facing the hemispherical radiator 702.

[0033] The bottom of the water injection rack 6 is equipped with a water valve that penetrates the dehumidification base 1 and connects to the outside. This valve guides external pure cold water into the device, enabling the utilization of waste heat from the heat exchange inside the device. The water injection rack 6 guides some pure cold water into the hemispherical spray rack 602. A certain gap is maintained between the hemispherical spray rack 602 and the hemispherical radiator 702. The spray valve 603 guides the pure cold water retained inside the hemispherical spray rack 602 and sprays it onto the outside of the hemispherical radiator 702. As the pure cold water flows along the surface of the hemispherical radiator 702, rapid heat exchange is achieved on the outer area of ​​the hemispherical radiator 702, resulting in pure hot water.

[0034] The water inlet rack 6 collects and retains the pure cold water sprayed by the water spray valve 603 through the overflow rack 601, so that the pure hot water after heat exchange continues to remain in the bottom area of ​​the hemispherical radiator 702 for continuous heat exchange. As the pure hot water accumulates, some of the pure hot water that overflows the overflow rack 601 flows to the nearest hot drain valve 102. The hot drain valve 102 is equipped with two pipes, which guide the pure hot water and the water in the buffer storage tank respectively.

[0035] Several sets of supporting paddle shafts 802 are arranged in a ring array on the outer peripheral wall of the heat exchange shaft frame 8. The top support rod of the supporting paddle shaft 802 is connected to the inner wall of the heat exchange arc plate 803 at multiple points. A water injection slip ring valve 801 is sleeved in the middle of the outer side of the heat exchange shaft frame 8. An external water pipe is provided on the outside of the water injection slip ring valve 801.

[0036] The heat exchange shaft bracket 8 is driven by the central shaft rod 703, which drives the support shaft 802 to rotate. The support shaft 802 drives the heat exchange arc plate 803 to rotate and contact the inner wall of the hemispherical radiator 702, causing the heat exchange arc plate 803 to absorb the heat dissipated from the inner wall of the hemispherical radiator 702. The water injection slip ring valve 801 is connected to external pure cold water through a water pipe, thereby guiding the pure cold water to be injected into the heat exchange arc plate 803 along the support shaft 802. The pure cold water circulates inside the heat exchange arc plate 803 to absorb the heat absorbed by the heat exchange arc plate 803, thereby reducing the heat retained on the inner wall of the hemispherical radiator 702.

[0037] During the rotation of the heat exchange arc plate 803 driven by the support shaft 802, the support shaft 802 agitates the pure hot water retained in the lower half of the hemispherical radiator 702, causing the pure hot water to continuously replace the temperature of the lower half of the hemispherical radiator 702, and causing the pure hot water to generate waves, which helps the pure hot water near the overflow rack 601 area to be effectively overflowed.

[0038] Metal pillars are provided at the bottom center and one side edge of the heat collection box cover 4. Several sets of connecting valves are provided on the surface of the metal pillars. Spiral heat exchange tubes 401 are provided between the metal pillars. Several sets of tube racks connected to the spiral heat exchange tubes 401 are provided on the bottom surface of the heat collection box cover 4. Several sets of water spray holes are provided on the bottom surface of the heat collection box cover 4.

[0039] The heat-locking chamber 101 receives residual heat emitted during the operation of the pure hot water, impeller heat exchanger 7, hot-press dehumidification chamber 1 3, and hot-press dehumidification chamber 2 5. Due to the rising characteristics of hot air, this residual heat air gathers near the heat collection box cover 4 and is released downwards. Thus, the spiral heat exchange tube 401 is connected to the external pure cold water through the metal column and water valve, causing the pure cold water to flow at a low speed inside the spiral heat exchange tube 401 to perform heat exchange treatment on the residual heat air trapped in the bottom area of ​​the heat collection box cover 4. If necessary, the water spray hole can guide some pure cold water to be sprayed from top to bottom to form a water mist structure, effectively absorbing the heat in the residual heat air and performing surface heat exchange and cooling treatment on structures such as the impeller heat exchanger 7.

[0040] Combining Embodiments 1 and 2, this device has significant advantages. First, it adopts a high-temperature primary dehumidification + low-temperature secondary dehumidification stage mode, coupled with a tortuous flow channel and symmetrical chamber design, resulting in high dehumidification efficiency and continuous operation during chamber dehydration, ensuring a constant temperature and low humidity environment. Second, it constructs a full-process waste heat utilization system, converting cold water into hot water through cold water spraying and heat exchange arc fin circulation, while recovering waste heat from the heat-locking chamber, reducing energy waste. Furthermore, it uses a dual-pipe hot drainage valve to orderly treat hot water and wastewater, balancing environmental protection and economy.
