Description

Technical Field

[0001] This invention belongs to the technical field of air water collection equipment, specifically relating to a vertical rotary air water collection device and air water collection method. Background Technology

[0002] Air-to-water extraction technology involves enriching the air with water vapor, condensing and collecting it to convert it into liquid fresh water. It is widely used in water supply in water-scarce areas, emergency water extraction in the wild, and industrial water purification. Rotary air-to-water extraction equipment, with its stable moisture absorption and regeneration cycle and wide adaptability to various environmental humidity ranges, has become one of the mainstream air-to-water extraction devices.

[0003] However, in existing rotary air-to-water intake equipment, the heat exchange components and condensation components are independent and separate structures, connected by multiple pipelines. Furthermore, the regeneration gas path has numerous connection sections, resulting in a complex overall gas path structure and many drawbacks. (1) The heat exchange and condensation components are arranged separately, resulting in low utilization of internal space, bulky overall volume, large heat transfer loss, low heat energy utilization, and direct reduction of water intake efficiency. (2) Too many regeneration gas path connection sections, large airflow ventilation resistance, high fan operating load, and high overall energy consumption of the equipment; (3) The condensate outlet path is winding and long, and condensate is easy to remain and accumulate in the pipe. This not only easily breeds bacteria and affects water quality, but also poses the risk of pipe leakage and blockage.

[0004] Therefore, there is an urgent need for a vertical rotary air intake device with a compact structure, short air path, and smooth condensate drainage. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vertical rotary air-water collection device and air-water collection method, which solves the problems of bulky structure and large heat loss caused by the separation of heat exchange and condensation components in existing rotary air-water collection equipment, large wind resistance and high energy consumption caused by the complicated regeneration gas path, and the problem of residual siltation caused by the tortuous discharge path of condensate.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a vertical rotary air-water collection device, comprising an adsorption wheel rotatably connected to a wheel container and capable of rotating around an axis, and a first airflow cavity and a second airflow cavity with one end opening respectively covering the two sides of the adsorption wheel; the openings on the first airflow cavity and the second airflow cavity are opposite to each other and respectively cover the desorption areas provided on the two end faces of the adsorption wheel; the other end opening of the first airflow cavity is connected to a plurality of first air ducts, and the other end opening of the second airflow cavity is connected to a plurality of second air ducts; the internal channels of the first air duct and the second air duct are arranged with a height difference along the pipeline direction; the lower end of the first air duct away from the first airflow cavity and the lower end of the second air duct away from the second airflow cavity are both connected to a fluid circulation cavity, and a drain outlet connected to a water storage tank is provided in the fluid circulation cavity; The second airflow cavity is equipped with a heating unit for heating the air fluid and a circulating fan for driving the air fluid to circulate. The wheel container is disposed inside the shell cavity of the outer shell. The adsorption wheel can divide the shell cavity into an air inlet cavity and an air outlet cavity. The first air duct and the second air duct are placed in the air inlet cavity. The outer shell is provided with an air outlet communicating with the air outlet cavity and a plurality of air inlet holes communicating with the air inlet cavity and corresponding to the first air duct and the second air duct. An air duct unit is provided inside the air outlet.

[0007] Optionally, a plurality of the first air ducts and the second air ducts are arranged in a circular array around the air inlet cavity, and the first air ducts are spaced apart from each other, the second air ducts are spaced apart from each other, and the first air ducts are spaced apart from each other.

[0008] Optionally, one end of the first duct is connected to a first arc-shaped air collection box disposed on the first airflow cavity, and one end of the second duct is connected to a second arc-shaped air collection box disposed on the second airflow cavity, and the fluid circulation cavity is annular; the first arc-shaped air collection box, the second arc-shaped air collection box, and the fluid circulation cavity are arranged coaxially.

[0009] Optionally, the adsorption wheel is an annular cylindrical disc, and the adsorption wheel has several ventilation channels that extend along its axial direction. The cross-section of the vent is triangular, and the wall surface of the vent is coated with a moisture-absorbing material.

[0010] Optionally, the opening of the first airflow cavity covering one side surface of the adsorption wheel is fan-shaped, and the central angle of the circle covering the adsorption wheel is 90° to 180°.

[0011] Optionally, the bottom of the outer shell is detachably connected to a chassis, and the water storage tank is movably attached to the chassis. The drain outlet of the fluid circulation chamber is detachably connected to the water inlet on the water storage tank.

[0012] Optionally, a water level switch may also be installed within the water storage tank.

[0013] Optionally, a temperature and humidity sensor may also be disposed within the first airflow cavity.

[0014] An air-to-water method, implemented using the aforementioned vertical rotary air-to-water device, includes the following steps; Step 1: The circulating fan drives the air fluid to circulate in the circulating air duct formed between the second airflow chamber, the area of ​​the adsorption wheel located in the desorption zone, the first airflow chamber, the first air duct, the fluid circulation chamber, and the second air duct, and can heat the air fluid circulating in the circulating air duct through the heating unit. Step 2: The air intake unit drives the ambient air into the air intake chamber through the air inlet. After passing over the outer walls of the first and second air ducts, the ambient air enters the air outlet chamber through the adsorption area on the adsorption wheel that is not covered by the opening mask at the end of the first and second air flow chambers. Water vapor in the ambient air is adsorbed by the area on the adsorption wheel located in the adsorption area. The ambient air dehumidified by the adsorption wheel is then discharged through the air outlet. Step 3: The adsorption wheel rotates around its axis, causing the area on the adsorption wheel that has entered the adsorption zone to continuously adsorb water vapor from the ambient air. This causes the fan-shaped surface on the adsorption wheel to move from the adsorption zone to the desorption zone. The airflow flowing in the circulating duct, heated by the heating unit, passes through the fan-shaped surface on the adsorption wheel located in the desorption zone, releasing the water vapor adsorbed on the adsorption wheel and generating regenerated gas that can continue to flow along the circulating duct. The regenerated gas flows along the circulating duct through the first and second ducts, exchanging heat with the ambient air entering the air inlet chamber through the walls of the second and first ducts, causing the water vapor in the regenerated gas to condense. The condensed liquid water enters the water storage tank through the drain of the fluid circulation chamber under the action of gravity. The condensed regenerated gas can then return to the second airflow chamber, be heated by the heating unit, and re-enter the desorption zone.

[0015] Optionally, the adsorption wheel described in step two can rotate intermittently or continuously around its axis.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: (1) By placing the first air duct and the second air duct inside the air inlet cavity, the present invention utilizes the regenerated gas to exchange heat with the ambient air entering the air inlet cavity through counter-current or cross-current flow when circulating in the first air duct and the second air duct. This achieves an integrated structural design for heat exchange and condensation functions, which not only significantly reduces the internal space occupied by the equipment and eliminates the heat transfer loss between traditional discrete components, thus improving the thermal energy utilization rate, but also significantly reduces the overall size and weight of the equipment, making the device lighter, easier to install and maintain. (2) The present invention adopts a first air duct and a second air duct to directly connect the first airflow cavity and the second airflow cavity, forming a closed circulating air duct, which greatly simplifies the connection structure of the regeneration air path. The short air path design effectively reduces the airflow resistance and reduces the operating load of the circulating fan, thereby significantly reducing the overall energy consumption of the equipment and improving energy utilization efficiency; (3) The internal channels of the first and second air ducts are arranged with varying heights along the pipeline route, and their lower ends are connected to the fluid circulation chamber. This fully utilizes the effect of liquid water flowing downstream by gravity, so that the condensed liquid water can be smoothly collected into the fluid circulation chamber and quickly discharged to the water storage tank through the drain outlet. This avoids the residue and accumulation of condensate in the pipeline, effectively prevents bacterial growth and water pollution, and also eliminates the risk of pipeline blockage or leakage caused by water accumulation, ensuring the cleanliness of the effluent water and the long-term reliability of the equipment operation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0020] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. Example 1

[0021] like Figures 1-5 As shown, a vertical rotary air-water extraction device includes an adsorption wheel 2 rotatably connected to a wheel container 1 and capable of rotating around an axis, and a first airflow cavity 3 and a second airflow cavity 4 with one end opening respectively covering the two side surfaces of the adsorption wheel 2. The openings on the first airflow cavity 3 and the second airflow cavity 4 are opposite to each other and respectively cover the desorption zones 5 located on the two side end faces of the adsorption wheel 2. The areas on the two side end faces of the adsorption wheel 2 that are not covered by the end openings of the first airflow cavity 3 and the second airflow cavity 4 are the adsorption zones. The positions of the adsorption zones and desorption zones 5 relative to the end openings of the first airflow cavity 3 and the second airflow cavity 4 are relatively constant, but are dynamically changing relative to the adsorption wheel 2.

[0022] It should be noted that the other end of the first airflow cavity 3 is connected to several first air ducts 6, and the other end of the second airflow cavity 4 is connected to several second air ducts 7. The internal channels of the first air ducts 6 and the second air ducts 7 are arranged with varying elevations along the pipeline route. The lower ends of the first air ducts 6 and the second air ducts 7, which are opposite to the first airflow cavity 3, are connected to the fluid circulation cavity 8. The second airflow cavity 4 is equipped with a heating unit 10 for heating the air fluid and a circulating fan 11 for driving the air fluid to circulate. Therefore, under the driving action of the circulating fan 11, such as Figure 3 As shown, the airflow can flow along the circulating air duct: second airflow chamber 4 → area on the adsorption rotor 2 located in the desorption zone 5 → first airflow chamber 3 → first air duct 6 → fluid circulation chamber 8 → second air duct 7 → second airflow chamber 4. This circulating air duct structure is arranged in a regular and orderly manner, effectively shortening the flow path of the regenerated gas and reducing airflow resistance and energy consumption of the circulating fan 11. After passing through the heating unit 10 in the second airflow chamber 4, the airflow is heated into high-temperature airflow, and then flows through the adsorption rotor 2 located in the desorption zone 5. The adsorption rotor 2 is a honeycomb porous core substrate in conventional technology, and the substrate is loaded with water adsorbents such as silica gel, molecular sieves, and composite hygroscopic salts. Therefore, the adsorption rotor 2 located in the adsorption zone can adsorb water vapor from the ambient air when in contact with it.

[0023] The above, such as Figure 3As shown, the wheel container 1 is disposed within the shell cavity of the outer casing 12. The adsorption wheel 2 can divide the shell cavity into an air inlet cavity 13 and an air outlet cavity 14. The first air duct 6 and the second air duct 7 are placed within the air inlet cavity 13. The outer casing 12 has an air outlet 15 communicating with the air outlet cavity 14 and several air inlet holes 16 communicating with the air inlet cavity 13 and corresponding to the first air duct 6 and the second air duct 7. An air intake unit 17 is disposed within the air outlet 15. Under the driving action of the air intake unit 17, ambient air can be introduced into the air inlet cavity 13 through the air inlet holes 16, and then enter the air outlet cavity 14 through the adsorption wheel 2 located in the adsorption zone, and finally be discharged through the air outlet 15. The wheel container 1 and the adsorption wheel 2 may not completely block the shell cavity, but the adsorption wheel 2 needs to be located on the flow path of the ambient air within the shell cavity. It should also be noted that during this process, as the ambient air passes through the adsorption rotor 2, water vapor can be adsorbed by the adsorption rotor 2. As the adsorption rotor 2 rotates around its axis, the area on the adsorption rotor 2 with adsorbed water vapor will move into the desorption zone 5. This allows the high-temperature airflow in the circulating air duct to flow through the adsorption rotor 2 in the desorption zone 5, which can promote the desorption and precipitation of adsorbed water vapor, thereby generating a high-temperature and high-humidity airflow, i.e., regeneration gas. Meanwhile, in this embodiment, the first air duct 6 is spaced apart from each other, the second air duct 7 is spaced apart from each other, and the first air duct 6 is spaced apart from the second air duct 7. This means that gaps are reserved between each pipe for the passage of ambient air. Therefore, as ambient air enters the air inlet chamber 13 through the air inlet 16, it can pass over the outer walls of the first air duct 6 and the second air duct 7 and concentrate its flow towards the adsorption rotor 2. This allows the regenerated gas to exchange heat with the ambient air entering the air inlet chamber 13 through the air inlet 16 as it flows along the circulation duct through the first air duct 6 and the second air duct 7, causing the water vapor in the regenerated gas to condense rapidly into liquid water. Under the influence of gravity, the liquid water flows into the fluid circulation chamber 8 through the first air duct 6 and the second air duct 7, which are arranged with varying heights, and is then discharged from the drain outlet 81 in the fluid circulation chamber 8 into the water storage tank 9. The regenerated gas discharged through the second air duct 7 can re-enter the second airflow cavity 4 with residual heat. After being further heated by the heating unit 10, it re-forms a high-temperature airflow and desorbs the water vapor adsorbed on the adsorption wheel 2 again. This process can be repeated to achieve heat recycling and further reduce the overall energy consumption of the system.

[0024] In this technical solution, the first air duct 6 and the second air duct 7 are integrated and arranged inside the air inlet cavity 13, so that the ambient air can form an orderly flow in the cavity, and the air fluid will complete the state transformation of high temperature air fluid and regeneration gas in the circulation duct. This structure achieves a high degree of integration in spatial layout, effectively solving the problem of structural bulkiness and heat loss caused by the separation of heat exchange and condensation components in traditional equipment.

[0025] Furthermore, this technical solution utilizes the structural design of setting a height difference between the first duct 6 and the second duct 7 along the pipeline route, so that the liquid water generated by condensation can flow smoothly to the lower fluid circulation chamber 8 under the action of gravity. This effectively avoids the stagnation and accumulation of condensate at the bends of the pipeline, eliminates the hidden dangers of bacterial growth and pipeline blockage from the source, ensures the cleanliness of the effluent water quality, and improves the long-term stability of the system.

[0026] In this embodiment, under normal operating conditions, the first air duct 6 and the second air duct 7, located within the housing 12, are arranged, but are not limited to, vertically, obliquely, or in an arc-shaped coiled arrangement, and are arranged in a circular array around the air inlet cavity 13. Specifically, as follows... Figure 3 , Figure 4 As shown, they are preferably arranged vertically. In addition, the fluid circulation cavity 8 is located below the lower end of the first air duct 6 and the second air duct 7. Its internal space can be configured as a funnel-shaped or sloping structure to facilitate the collection of condensate towards the drain outlet 81, further assisting the condensate to flow quickly to the drain outlet 81 under the action of gravity and preventing water accumulation.

[0027] Furthermore, in this embodiment, the circulating fan 11, the induced draft unit 17, and the heating unit 10 are existing technologies. The first airflow cavity 3, the second airflow cavity 4, and the fluid circulation cavity 8 are all shell components with hollow fluid channels. For example, Figure 3 As shown, the opening of the first airflow cavity 3 covering one side surface of the adsorption wheel 2 is fan-shaped, and the central angle covering the adsorption wheel 2 is 90° to 180°, preferably 120°.

[0028] Meanwhile, a chassis 21 is detachably connected to the bottom of the outer shell 12, and the water tank 9 is movably mounted on the chassis 21. The drain outlet 81 of the fluid circulation chamber 8 is detachably connected to the inlet 22 of the water tank 9. Specifically, the chassis 21 and the outer shell 12 can be quickly disassembled and assembled using methods including but not limited to snap-fit ​​connections, threaded connections, or magnetic connections, so as to facilitate the removal of the chassis 21 to take out the water tank 9 for cleaning, replacement, or maintenance. The drain outlet 81 of the fluid circulation chamber 8 and the inlet 22 of the water tank 9 can be detachably connected by a movable interlocking method, as shown in the following example. Figure 3 As shown.

[0029] Furthermore, in this embodiment, such as Figure 3 , Figure 4 As shown, one end of the first air duct 6 is connected to the first arc-shaped air collection box 18 disposed on the first airflow cavity 3, and one end of the second air duct 7 is connected to the second arc-shaped air collection box 19 disposed on the second airflow cavity 4. The fluid circulation cavity 8 is annular. The first arc-shaped air collection box 18, the second arc-shaped air collection box 19, and the fluid circulation cavity 8 are arranged coaxially. By setting the first arc-shaped air collection box 18 and the second arc-shaped air collection box 19, the structures of the fluid circulation cavity 8, the first arc-shaped air collection box 18, and the second arc-shaped air collection box 19 are matched, which makes the space utilization of each structure inside the outer shell 12 more compact, further reducing the volume ratio of the equipment and facilitating modular assembly and maintenance.

[0030] The adsorption wheel 2 is driven to rotate by a rotary drive unit, which is conventionally used in this field. The rotary drive unit is located at the bottom center of the wheel container 1, and preferably uses a stepper motor. The output shaft of the stepper motor is coaxially arranged with the shaft of the adsorption wheel 2, and the output shaft of the stepper motor is connected to the central connection part of the adsorption wheel 2 through a transmission connector to transmit torque.

[0031] In this embodiment, the adsorption wheel 2 is an annular cylindrical disc, and the adsorption wheel 2 has several ventilation channels 20 extending along its axial direction. The cross-section of each ventilation channel 20 is triangular. Figure 5 As shown. The walls of the ventilation channels 20 are coated with a moisture-absorbing material, which is one or more of the following: metal-organic framework materials, molecular sieves, silica gel, or composite moisture-absorbing materials. Preferably, MOF materials with reversible water vapor adsorption properties are used. By setting the ventilation channels 20 with a triangular cross-section, sufficient airflow area is ensured while increasing the structural strength of the adsorption rotor 2, preventing deformation during high-speed rotation or long-term operation. Example 2

[0032] Based on Embodiment 1, a vertical rotary air-water intake device further includes a controller, a temperature and humidity sensor, and a water level switch (not shown in the figure). The controller is electrically connected to the circulating fan 11, the induced draft unit 17, the heating unit 10, and the rotary drive unit.

[0033] Temperature and humidity sensors are installed at multiple monitoring points within the housing and circulating air duct to collect temperature and humidity parameters at corresponding locations and transmit the monitoring data to the controller in real time. The controller then dynamically adjusts the rotation speed of the circulating fan 11, the power of the heating unit 10, and the rotation speed of the rotary drive unit based on the received temperature and humidity parameters to optimize adsorption and desorption efficiency, ensuring that the device maintains optimal water extraction performance under different environmental humidity conditions.

[0034] A water level switch is installed inside the water storage tank 9 to detect the water level. When the water level reaches the preset upper limit, the water level switch sends a signal to the controller, which then stops the operation of the control device or issues a full water warning to prevent overflow. When the water level falls below the preset lower limit, the controller resumes normal operation or issues a water shortage warning to ensure continuous and stable system operation. Example 3

[0035] like Figures 1-5 As shown, based on Embodiment 1, an air-to-water method includes the following steps; Step 1: The circulating fan 11 drives the air fluid to circulate in the circulating air duct formed between the second airflow chamber 4, the area of ​​the desorption zone 5 on the adsorption wheel 2, the first airflow chamber 3, the first air duct 6, the fluid circulation chamber 8, and the second air duct 7, and can heat the air fluid circulating in the circulating air duct through the heating unit 10. Step 2: The air intake unit 17 drives the ambient air into the air intake cavity 13 through the air inlet 16. After passing over the outer walls of the first air duct 6 and the second air duct 7, the ambient air enters the air outlet cavity 14 through the adsorption area on the adsorption wheel 2 that is not covered by the end openings of the first airflow cavity 3 and the second airflow cavity 4. Water vapor in the ambient air is adsorbed by the area on the adsorption wheel 2 located in the adsorption area. The ambient air dehumidified by the adsorption wheel 2 is discharged through the air outlet 15. Step 3: The adsorption wheel 2 rotates around its axis, causing the area on the adsorption wheel 2 that has entered the adsorption zone to continuously adsorb water vapor from the ambient air. This causes the fan-shaped surface on the adsorption wheel 2 to move from the adsorption zone to the desorption zone 5. The airflow flowing in the circulation duct, heated by the heating unit 10, passes through the fan-shaped surface on the adsorption wheel 2 located in the desorption zone 5, releasing the water vapor adsorbed on the adsorption wheel 2 and generating regenerated gas that can continue to flow along the circulation duct. The regenerated gas flows along the circulation duct through the first duct 6 and the second duct 7, and can exchange heat with the ambient air entering the air inlet chamber 13 from the air inlet hole 16 through the pipe walls of the second duct 7 and the first duct 6, so that the water vapor in the regenerated gas condenses. The condensed liquid water enters the water storage tank 9 through the drain outlet 81 of the fluid circulation chamber 8 under the action of gravity. The regenerated gas after condensation can return to the second airflow chamber 4, be heated by the heating unit 10, and then re-enter the desorption zone 5.

[0036] As described above, the adsorption rotor 2 mentioned in step two can rotate intermittently or continuously around its axis. When rotating continuously, the rotation speed of the adsorption rotor 2 is adjusted according to the ambient air humidity and water intake requirements to balance adsorption efficiency and desorption completeness. When rotating intermittently, the adsorption rotor 2 stays in the adsorption zone for a predetermined time before rotating to the desorption zone 5, where it stays for a predetermined time to complete the desorption process, and then rotates back to the adsorption zone, repeating this cycle. By controlling the rotation mode and speed of the adsorption rotor 2, the energy efficiency ratio and water production rate of the device under different operating conditions can be further flexibly adjusted to meet different operational needs.

[0037] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
