Description

Technical Field

[0001] This invention relates to the field of technology, and more specifically to a combined air-water extractor. Background Technology

[0002] With the global water shortage becoming increasingly severe, extracting water from the air has become an important research direction for alleviating water scarcity. Air-based water extraction primarily targets outdoor natural air, aiming to convert water vapor in the air into liquid water as much as possible. However, the difficulty of air-based water extraction is closely related to the air's moisture content; extracting water from air with low moisture content is extremely challenging.

[0003] Traditional condensing air-to-water extractors rely on lowering the air temperature to bring water vapor to its dew point, causing it to condense into liquid water. These devices often fail to start, produce no water, or produce very little water in environments with low humidity (RH below 30%). While rotary desiccant technology can effectively absorb moisture from the air, existing rotary dehumidifiers suffer from the problem of high-temperature air causing the absorbed moisture to evaporate during regeneration, resulting in a double waste of heat and moisture. Consequently, their application for efficient air-to-water extraction has not been fully developed.

[0004] Currently, existing technologies have the following shortcomings: 1. Traditional condenser-type air-to-water extractors have extremely low water extraction efficiency or may not even be able to start operating in low humidity environments (relative humidity below 30%). This is because the water vapor partial pressure in low humidity air is low, requiring the air to be cooled to an extremely low dew point temperature to extract moisture. This drastically increases cooling energy consumption while the water extraction volume is extremely limited, resulting in poor economic efficiency. 2. In existing rotary dehumidifier systems, during the regeneration process, high-temperature air carrying evaporated moisture is directly discharged outdoors, resulting in a double waste of heat and moisture. This is because when the rotor rotates into the regeneration zone, the high-temperature regeneration air causes the moisture adsorbed on the adsorbent to evaporate, and the hot, humid air carrying a large amount of water vapor is directly discharged, wasting both heat energy and moisture resources. Therefore, how to provide a combined air-water extractor that can stably and efficiently extract water in low-humidity environments and improve overall energy utilization efficiency and water extraction efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a combined air-water extractor that can still extract water stably and efficiently in low humidity environments, thereby improving overall energy utilization efficiency and water extraction efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A combined air-to-water extractor includes: The housing includes an air pretreatment component, a heat pump system, and a rotor assembly arranged sequentially along the airflow direction inside the housing. The housing is provided with an adjustable air inlet and an adjustable air outlet. A bracket inside the housing divides the interior of the housing into a moisture absorption zone and a regeneration zone. The air pretreatment assembly includes a filter screen, a primary surface cooler, and a water collection tray arranged sequentially on the air inlet path of the moisture absorption zone. The adjustable air inlet is located at the front end of the housing and communicates with the airflow of the filter screen. The primary surface cooler is located at the end of the filter screen away from the adjustable air inlet, and the water collection tray is located below the primary surface cooler. The rotating wheel assembly includes a rotating wheel body and a drive motor. The rotating wheel body is rotatably disposed inside the housing, and the drive motor is rotatably connected to the rotating wheel body. The heat pump system includes a secondary surface cooler and a water collection tray. The secondary surface cooler is located at the air outlet end of the rotor body, and the water collection tray is located at the bottom of the secondary surface cooler.

[0007] Furthermore, it also includes a regeneration component, which includes an electric heater and a horizontal fan, both of which are located within the regeneration zone. The horizontal fan faces the secondary surface cooler, and the electric heater is located at the end of the horizontal fan away from the secondary surface cooler.

[0008] Furthermore, the air pretreatment also includes a centrifugal fan, which is disposed inside the housing and the outlet of the centrifugal fan is connected to the adjustable outlet of the housing. The centrifugal fan is located downstream of the secondary surface cooler.

[0009] Furthermore, it also includes a drainage pipe, which is connected to the water collection tray and the water receiving tray.

[0010] Furthermore, it also includes an intelligent control unit, which includes a controller and a humidity sensor and a temperature sensor electrically connected to the controller.

[0011] Furthermore, the surface of the rotating wheel body is coated with an adsorption material.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a combined air-water extractor, which has the following advantages: 1) The water vapor in the low humidity air is adsorbed and enriched by the rotating adsorption component, and then the water is released by the condensation component, which breaks through the technical bottleneck of traditional condensation water dispensers that cannot be turned on, do not produce water or produce very little water in environments with relative humidity below 30%. 2) The intake air is pre-cooled and cooled by a primary surface cooler to reduce the intake air temperature and improve the moisture absorption efficiency of the rotor; the regenerated humid and hot air is condensed and water is extracted by a secondary surface cooler, achieving dual extraction of moisture. 3) It can stably extract water in extremely dry environments, demonstrating excellent efficiency. The entire water extraction process will not pollute the environment, fully embodying the concept of environmental protection. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] See Figure 1-2 This invention discloses a combined air-water extractor, comprising: The outer casing 1 and the air pretreatment components, heat pump system and rotor assembly 6 arranged sequentially inside the outer casing 1 along the airflow direction are provided. The outer casing 1 is provided with an adjustable air inlet 2 and an adjustable air outlet 12. The support inside the outer casing 1 is provided to divide the interior of the outer casing 1 into a moisture absorption zone and a regeneration zone. The air pretreatment assembly includes a filter screen 3, a primary surface cooler 4, and a water collection tray 5, which are sequentially arranged on the air inlet path of the moisture absorption zone. The adjustable air inlet 2 is located at the front end of the housing 1 and communicates with the airflow of the filter screen 3. The primary surface cooler 4 is located at the end of the filter screen 3 away from the adjustable air inlet 2. The water collection tray 5 is located below the primary surface cooler 4. The filter screen 3 is used to intercept dust, particulate matter, and other impurities in the air to protect the subsequent components. The primary surface cooler 4 pre-cools and lowers the temperature of the incoming air, causing some water vapor to condense and precipitate, while lowering the air temperature to improve the moisture absorption efficiency of the impeller. The water collection tray 5 is used to collect the condensate produced by the primary condensation. The rotating wheel assembly 6 includes a rotating wheel body and a drive motor. The rotating wheel body is rotatably mounted inside the housing 1, and the drive motor is rotatably connected to the rotating wheel body. Under the control of the intelligent control unit, the drive motor drives the rotating wheel body to rotate at a set speed of 10-15 revolutions per hour to ensure that the adsorbent fully adsorbs moisture in the moisture absorption zone and regenerates in a timely manner in the regeneration zone. The heat pump system includes a secondary surface cooler 9 and a water collection tray 10. The secondary surface cooler 9 is set at the air outlet end of the rotor body, and the water collection tray 10 is set at the bottom of the secondary surface cooler 9. By setting the secondary surface cooler 9, the high temperature and high humidity air from the rotor regeneration zone enters the secondary surface cooler 9, and the water vapor quickly condenses into liquid water and drips into the water collection tray 10 below.

[0018] In this embodiment, a regeneration component is also included, comprising an electric heater 8 and a horizontal fan 7. Both the electric heater 8 and the horizontal fan 7 are located within the regeneration zone. The horizontal fan 7 faces the secondary surface cooler 9, and the electric heater 8 is located at the end of the horizontal fan 7 furthest from the secondary surface cooler 9. The horizontal fan 7 is used to send the extracted dry air into the regeneration duct, and the electric heater 8 is used to heat the regeneration air to 100-120°C. The high-temperature regeneration air blows across the regeneration zone of the rotor body, causing the water adsorbed on the adsorbent to evaporate rapidly, thereby regenerating the rotor body. The horizontal fan 7, the electric heater 8, the secondary surface cooler 9, and the regeneration zone of the rotor body together form a heat recovery loop. In this loop, the high-temperature air carrying a large amount of water vapor is condensed and decomposed by the secondary surface cooler 9, and the cooled dry air is sent back to the front of the rotor to mix with the processed air and then recycled.

[0019] In this embodiment, the air pretreatment also includes a centrifugal fan 11. The centrifugal fan 11 is installed inside the housing 1 and its outlet is connected to the adjustable air outlet 12 of the housing 1. The centrifugal fan 11 is located downstream of the secondary surface cooler 9 and is positioned behind the impeller assembly 6 and in front of the adjustable air outlet 12. It provides power for airflow, causing outside air to be continuously drawn into the housing 1 and pushing the air to flow evenly inside the equipment.

[0020] In this embodiment, a drainage pipe is also included, which is connected to the water collection tray 5 and the water receiving tray 10 to facilitate the transportation of the collected liquid water for subsequent use.

[0021] In this embodiment, an intelligent control unit is also included. The intelligent control unit includes a controller and a humidity sensor and a temperature sensor electrically connected to the controller. The controller is electrically connected to a drive motor, an electric heater 8, a horizontal fan 7, and a centrifugal fan 11. The controller automatically adjusts the operating status of each component according to the environmental parameters monitored in real time by the humidity sensor and the temperature sensor.

[0022] In this embodiment, the surface of the rotor body is coated with an adsorbent material selected from silica gel, molecular sieve, or molecular sieve-silica gel composite material, which can adsorb moisture in the air.

[0023] In addition, in this embodiment, a diversion channel is provided between the rotor body and the first-stage surface cooler 4 to extract a portion of the dried air from the processed air as regeneration air.

[0024] Work process

[0025] Centrifugal fan 11 draws outside air into the adjustable air inlet. The air first passes through filter screen 3 to filter impurities, and then enters the first-stage surface cooler 4. Inside the primary surface cooler 4, the air temperature decreases, and the water vapor in it condenses and precipitates upon cooling, achieving preliminary dehumidification and cooling. Next, air enters the rotor body for adsorption, further removing the remaining moisture. To ensure that the rotor body continues to have efficient moisture absorption capacity, a diversion channel is provided between the rotor and the first-stage surface cooler 4. The horizontal fan 7 draws some of the dried air from this channel and sends it into the electric heating pipe above. The air is heated to 100-120°C by electric heating. When the hot air flows through the rotor, it causes the moisture adsorbed on the rotor to evaporate rapidly. The hot air carrying water vapor is then introduced into the secondary surface cooler 9. In the secondary surface cooler 9, the moisture in the hot air is condensed and precipitated again. The cooled dry air is sent back to the front of the rotor, forming a cycle. Finally, the air, after being thoroughly dried and heated, is discharged from the system by centrifugal fan 11 and delivered to the outdoor environment.
