Description

Technical Field

[0001] This invention relates to the field of water resource acquisition technology, and in particular to a wind-powered air-source water extraction device. Background Technology

[0002] With the increasing scarcity of freshwater resources globally, air-to-water (AWG) technology has become an important way to solve water problems in remote, arid, and island regions without power grid coverage. Existing AWG devices mostly use electrically driven compressors for refrigeration and condensation, resulting in high energy consumption and poor environmental adaptability.

[0003] To reduce dependence on electricity, existing technologies have attempted to utilize wind power to directly drive compressors, combined with pneumatic expansion refrigeration for water extraction—a purely mechanical approach. However, this type of solution suffers from three fatal flaws in practical engineering: Power mismatch: Large fluctuations in wind energy make it extremely difficult for the compressor to start when there is system back pressure. Forcing a direct connection can easily suffocate the fan or damage the drive shaft.

[0004] Gas circuit "ice blockage" paralysis: Existing solutions usually allow compressed air rich in moisture to be depressurized and expanded directly. The moisture will directly sublimate into ice in the instant of rapid cooling, quickly blocking the pipeline and valve, causing the system to shut down.

[0005] Water quality safety is difficult to guarantee: Purely mechanical off-grid systems lack power support and cannot perform deep purification such as ultraviolet sterilization. The collected natural condensate is prone to bacterial growth and cannot meet the standards for direct drinking water.

[0006] Therefore, there is an urgent need for a high-efficiency wind-powered water intake device that can adapt to wind fluctuations, completely eliminate the risk of ice blockage, and has a built-in micro-electric sterilization function. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a wind-powered air-water extraction device to solve the problems mentioned in the background art.

[0008] To achieve the above technical objectives, this invention proposes a wind-powered air-water collection device, comprising a power and flexible transmission module, a compression and pre-cooling air storage module, a condensation water collection module, a collection and deep purification module, and an energy storage control unit connected in series. Among them: the power and flexible transmission module is used to capture wind energy and convert it into mechanical power to drive the compression and pre-cooling gas storage module; The compression and pre-cooling air storage module is used to convert mechanical energy into the internal energy of high-pressure air and output high-pressure humid air to the condensate water intake module; The condensate intake module includes a high-pressure proportional flow divider valve, a vortex tube, and a sleeve-type counter-current heat exchanger. The input end of the high-pressure proportional flow divider valve is connected to the gas output end of the compression and pre-cooling gas storage module. Its branch gas path A is connected to the gas inlet end of the vortex tube, and its branch gas path B is directly connected to the inner tube inlet of the sleeve-type counter-current heat exchanger. The cold gas exhaust port of the vortex tube is connected to the outer tube inlet of the sleeve-type counter-current heat exchanger. The liquid outlet of the inner tube of the sleeve-type counter-current heat exchanger is connected to the collection and deep purification module. The energy storage control unit is electrically connected to the electronic control components or power generation components in the above modules.

[0009] Furthermore, the power and flexible transmission module mainly consists of a wind turbine, a main drive shaft, a centrifugal clutch, a driven shaft, and a coaxial generator; The hub of the wind turbine is rigidly fixed to the input end of the main drive shaft. The output end of the main drive shaft is connected to the driving plate of the centrifugal clutch, and the driven plate of the centrifugal clutch is connected to the driven shaft. The coaxial generator is sleeved or connected in parallel to the middle section of the main drive shaft, and the output end of the coaxial generator is electrically connected to the energy storage control unit.

[0010] Furthermore, the compression and pre-cooling gas storage module mainly consists of a scroll air compressor, an automatic unloading valve, a finned precooler, and a high-pressure gas storage tank. The end of the driven shaft is connected to the main shaft of the scroll air compressor via a coupling; the high-pressure exhaust port of the scroll air compressor is connected to the inlet of the finned precooler via a high-pressure resistant pipeline, and the outlet of the finned precooler is connected to the high-pressure air tank; the bottom exhaust port of the high-pressure air tank is connected to the input of the high-pressure proportional flow divider valve.

[0011] Furthermore, the scroll air compressor has an automatic unloading valve connected in parallel at the intake or exhaust end. The automatic unloading valve is controlled by the energy storage control unit and is used to enable the scroll air compressor to start under no-load conditions. A safety pressure relief valve is provided on the top of the high-pressure air tank.

[0012] Furthermore, the hot air end exhaust port of the vortex tube is open to the air, and its cold air end exhaust port is connected to the outer tube inlet of the sleeve counterflow heat exchanger through an insulated air duct; the outer tube exhaust port of the sleeve counterflow heat exchanger is directly discharged to the air.

[0013] Furthermore, the collection and deep purification module mainly consists of a high-pressure gas-water separator, a liquid level sensor, an electromagnetic drain valve, a multi-stage water purification component, and an atmospheric pressure water storage tank. The liquid outlet of the inner tube of the sleeve-type countercurrent heat exchanger is vertically connected downwards to the top inlet of the high-pressure gas-water separator; the top of the high-pressure gas-water separator is equipped with exhaust micro-holes.

[0014] Furthermore, a liquid level sensor is installed inside the cavity of the high-pressure gas-water separator, and an electromagnetic drain valve is connected to its bottom drain port; both the liquid level sensor and the electromagnetic drain valve are electrically connected to the energy storage control unit.

[0015] Furthermore, the outlet of the electromagnetic drain valve is connected in series with multiple water purification components, and the final outlet of these multiple water purification components flows into the atmospheric pressure water storage tank at the bottom through a guide pipe.

[0016] Furthermore, the multi-stage water purification component is equipped with a PP cotton coarse filter layer, a sintered activated carbon adsorption layer, and a flow-through UV-C ultraviolet sterilization module arranged sequentially along the fluid direction; the flow-through UV-C ultraviolet sterilization module is powered by an energy storage control unit.

[0017] Furthermore, the energy storage control unit is equipped with control logic: when the speed of the main drive shaft is lower than the set threshold, the centrifugal clutch is controlled to be in a disengaged state; when the speed reaches the set threshold, the friction blocks inside the centrifugal clutch open due to centrifugal force to achieve power coupling.

[0018] Compared with the prior art, the beneficial effects of the present invention include: 1. This invention utilizes vortex cooling air to reverse-cool another path of humid air that is kept under high pressure. By taking advantage of the thermodynamic properties of the extremely high dew point under high pressure, water vapor is instantly and massively condensed into liquid water, which greatly improves the efficiency of pure physical water extraction and the continuous operation stability of the system in extreme environments.

[0019] 2. This invention, through the coordinated linkage of a centrifugal clutch and an automatic unloading valve, perfectly resolves the predicament of compressor stalling under pressure caused by wind fluctuations, achieving smooth no-load start-up; at the same time, through a coaxial micro generator, it achieves self-sufficient micro-electric control, which not only precisely drives various automatic control valves, but also ensures the operation of the ultraviolet sterilization module, completely eliminating water quality hazards in water intake areas far from the grid.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The technical solution of the present invention provides a wind-powered air-to-water extraction device, such as... Figure 1 As shown, the device mainly includes four core fluid and mechanical modules: a power and flexible transmission module, a compression and pre-cooling gas storage module, a condensate water extraction module, a collection and deep purification module, and an energy storage control unit independent of the above modules; each physical module is connected in series, and the energy storage control unit is electrically connected to the electronic control components and power generation components in each module.

[0023] The power and flexible transmission module is used to capture wind energy and convert it into mechanical power with adaptive start-stop capability; such as Figure 2 As shown, it mainly consists of a wind turbine, a main drive shaft, a centrifugal clutch, a driven shaft, and a coaxial generator. The hub of the wind turbine is rigidly fixed to the input end of the main drive shaft. The middle section of the main drive shaft is fitted with or connected in parallel to a coaxial generator. The output end of the generator is electrically connected to the energy storage control unit to provide control power.

[0024] The output end of the main drive shaft is connected to the driving plate of the centrifugal clutch, and the driven plate of the centrifugal clutch is connected to the driven shaft. When the speed of the main drive shaft is lower than the set threshold, the clutch is in the disengaged state. When the threshold is reached, the friction blocks open due to centrifugal force to achieve power coupling.

[0025] The compression and pre-cooling gas storage module is used to convert mechanical energy into the internal energy of high-pressure air and complete the initial heat exchange. (Refer to...) Figure 3 It mainly consists of a scroll air compressor, an automatic unloading valve, a finned precooler, and a high-pressure air tank. The end of the driven shaft is connected to the main shaft of the scroll air compressor via a coupling. An automatic unloading valve is connected in parallel to the inlet or outlet of the scroll air compressor. This unloading valve is controlled by the energy storage control unit and is used to achieve no-load start-up. The high-pressure exhaust port of the scroll air compressor is connected to the inlet of the finned precooler, which is exposed to the natural environment, via a high-pressure resistant pipeline. The outlet of the precooler is connected to the high-pressure air tank. A safety pressure relief valve is provided on the top of the high-pressure air tank, and the set opening pressure is usually 1.2MPa-1.5MPa.

[0026] The condensate water intake module is the core thermodynamic actuator for solving the "ice blockage" problem caused by pressure reduction and achieving efficient water intake. (Refer to...) Figure 4 It mainly consists of a high-pressure proportional flow divider valve, a vortex tube, and a sleeve-type counter-current heat exchanger.

[0027] The bottom exhaust port of the high-pressure gas storage tank is connected to the input end of the high-pressure proportional flow divider valve, dividing it into gas path A and gas path B. The pipeline of gas path A is connected to the inlet end of the vortex tube. The hot gas end exhaust port of the vortex tube is open to the air, and its cold gas end exhaust port is connected to the outer tube inlet of the sleeve counterflow heat exchanger through an insulated air duct. The pipeline of gas path B is directly connected to the inner tube inlet of the sleeve counterflow heat exchanger. The outer tube exhaust port of the sleeve counterflow heat exchanger is directly discharged to the air, and the inner tube liquid outlet is connected to the next module.

[0028] The collection and deep purification module is used for gas-liquid separation and safe drinking water purification. (Refer to...) Figure 5 It mainly consists of a high-pressure gas-water separator, a liquid level sensor, an electromagnetic drain valve, a multi-stage water purification assembly, and an atmospheric pressure water storage tank. The liquid outlet of the inner tube of the sleeve-type counter-current heat exchanger is vertically connected downwards to the top inlet of the high-pressure gas-water separator. The top of the separator is equipped with exhaust micro-holes. A liquid level sensor is installed inside the high-pressure gas-water separator cavity, and an electromagnetic drain valve is connected to the bottom drain port. Both are electrically connected to the energy storage control unit. The outlet of the electromagnetic drain valve is connected in series downwards to the multi-stage water purification assembly. Inside the assembly, along the fluid direction, there is a PP cotton coarse filter layer, a sintered activated carbon adsorption layer, and a through-flow UV-C ultraviolet sterilization module. The ultraviolet sterilization module is powered by the energy storage control unit. The final outlet of the multi-stage water purification assembly flows into the atmospheric pressure water storage tank at the bottom through a guide pipe.

[0029] The working cycle of this invention is performed automatically according to the following steps: Phase 1: Back Pressure-Free Start-up and Initial Start-up of the High-Pressure Energy Storage System. The wind turbine, driven by wind power, rotates the main drive shaft, and the coaxial micro-generator generates electricity, which is stored in the energy storage control unit. At this time, the energy storage control unit keeps the automatic unloading valve in a normally open state to ensure no high back pressure inside the scroll air compressor. When the wind speed increases and the main drive shaft speed reaches the activation threshold of the centrifugal clutch, the clutch automatically engages, driving the compressor to start smoothly under no-load conditions. Subsequently, the unloading valve closes, and the compressor compresses the intake humid air. The high-temperature, high-humidity, and high-pressure air flows through a finned precooler, where it is initially cooled by natural air cooling before being stored in a high-pressure air tank (the system pressure is maintained at approximately 0.8-1.2 MPa).

[0030] The second stage involves gas diversion and anti-icing countercurrent condensation. High-pressure humid air from the high-pressure storage tank enters the proportional flow divider valve and is physically divided into two streams. Approximately 60% of the high-pressure gas enters the vortex tube, where it undergoes rapid expansion and vortex separation within the vortex chamber, generating extremely cold air below zero degrees Celsius. This cold air is then introduced into the outer tube cavity of the sleeve-type countercurrent heat exchanger. Simultaneously, the remaining approximately 40% of the high-pressure gas, acting as the target water intake fluid, does not undergo pressure reduction and expansion but remains at a high pressure of 0.8-1.2 MPa before entering the inner tube of the sleeve-type countercurrent heat exchanger. Because the gas in the inner tube is under high pressure, its dew point temperature is extremely high. When the extremely cold air from the outer tube flows against the outer wall of the inner tube, the temperature of the high-pressure humid air in the inner tube drops sharply, and water vapor instantly condenses into a large amount of liquid water on the inner wall, sliding down. This physical isolation and diversion heat exchange mechanism completely avoids the fatal "icing blockage" phenomenon caused by the direct pressure reduction and expansion of humid air at the throttling valve or nozzle.

[0031] The third stage: The gas-liquid mixture (liquid water and remaining high-pressure cold air) released from the inner tube flows into the high-pressure gas-water separator. The high-pressure air is released through the top exhaust micro-hole, and the liquid water accumulates at the bottom. When the liquid level sensor detects that the water level has reached the set upper limit, the energy storage control unit commands the electromagnetic drain valve to open. Utilizing the residual high-pressure air potential energy in the separator, the accumulated water is forcefully pushed out of the valve. The water flows at high speed through multi-stage water purification components, sequentially filtering out dust condensation nuclei and adsorbing odors. In the final stage, it undergoes instantaneous UV-C ultraviolet light sterilization driven by micro-electricity. Finally, purified water that meets safe direct drinking standards flows into the atmospheric pressure storage tank for users to access. The entire process achieves micro-electricity self-sufficiency in both power and purification.

[0032] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
