Description

Technical Field

[0001] The present invention relates to the technical field of air condensation for water production, and more particularly to an air condensation water production system powered by wind-solar complementary power supply. Background Art

[0002] An ocean liner needs to carry hundreds of tons of fresh water during navigation. During a long voyage, the water quality cannot be guaranteed. Using seawater desalination technology is an effective technology for supplementing fresh water, but it requires a large amount of fuel. The islands in the South China Sea of our country are surrounded by the sea. Under the action of sea breeze and high temperature, evaporation is intense, precipitation cannot be stored, and fresh water cannot be supplied. Especially in areas where it is difficult to obtain fresh water sources through groundwater, rivers and lakes, water resources become extremely precious. To solve the problem of water shortage in water-scarce areas, people have invented air water production technology, which can "extract water" from the air, that is, an air water production machine is used. Its working principle is to exchange heat between the air and the evaporator in the refrigeration system, reduce the temperature of the air below the dew point, and the water vapor in the air condenses and is converted into water resources to become domestic water, agricultural water, and emergency disaster relief water sources.

[0003] In the prior art, an air water production machine is used to produce water in high-temperature areas. However, most machines require a refrigeration system. The direct heat exchange between outdoor air and the evaporator results in a very low set value of the evaporation temperature, which is -5°C to -20°C. The operating conditions of the compressor are harsh, the COP is very low, and most of them focus on collecting water vapor in the air.

[0004] In addition, there is also a technology that uses solar panels as energy to extract water from the air. However, this water production machine using solar cells still has defects such as complex structure, high cost, difficult maintenance, and poor stability and sustainability.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0040] Embodiment

[0041] As Figures 1-11 shown, the present invention provides an air condensation water production system for wind-solar hybrid power supply, including a power generation device and an air condensation water production device electrically connected to the power generation device. The air condensation water production device includes a water production unit, a water storage unit, a water supply unit, and a heat storage unit. The water production unit is connected to the water storage unit, and the water storage unit is connected to the water supply unit; the heat storage unit is respectively connected to the water production unit, the water storage unit, and the water supply unit.

[0042] The power generation device includes a wind turbine 1 and a solar photovoltaic module 2 connected to the wind turbine 1. A flat plate collector 3 is connected to the power generation device for collecting the heat of the sun. The solar photovoltaic module 2 is fixed to the tower barrel of the wind turbine 1 through a bracket. The wind power generation and the solar photovoltaic module 2 provide green power for this device after inversion, and a storage battery can be set to store electric energy. When specifically setting, with the tower barrel of the wind turbine 1 as the center, the solar photovoltaic module 2 and the flat plate collector 3 are arranged in the south direction, and an air condensation water production device is arranged in the north direction. The flat plate collector 3 is installed with a fixed bracket at the local optimal inclination angle, and the bracket is installed on a reinforced concrete pile foundation on the ground. It can operate continuously during the period with sufficient sunlight. The heat collection branch flows into the heat storage tank 7, and the heat collection branch where the flat plate collector is located is kept in a closed state by closing the solenoid valve before sunrise and after sunset. The solar photovoltaic module 2 is composed of multiple polycrystalline silicon photovoltaic panels, and its bracket is fixed to the tower barrel of the wind turbine 1. The best installation height is such that the light shadow of the photovoltaic module does not affect the heat collection effect of the lower flat plate collector 3. The solar photovoltaic module 2 is driven by a motor to perform north-south light tracking to improve the power generation efficiency. The wind turbine 1 uses a horizontal axis three-blade upwind form, and the wind turbine 1 automatically faces the wind through a pitch system.

[0043] The water production unit includes an air compressor 4, a blower 5 and a cyclone chamber 9. The cyclone chamber 9 adopts the form of a cyclone separator, which is a common device for dust purification in the industrial field. The upper part of the cyclone chamber 9 is set as a cylindrical structure with tangential air inlet, the middle part is set as a reducing conical frustum structure with a larger upper part and a smaller lower part, and the lower part is set as a cylindrical water collection chamber structure. In order to strengthen the heat exchange between hot and cold gases, a first spiral coil 901 is arranged inside the cyclone chamber 9, which is similar to the outer contour of the cyclone chamber 9 and is reduced in proportion. The inner wall of the first spiral coil 901 adopts a micro-rib structure, and cold air flows inside the pipe to form a cold source. Moist air enters the cyclone chamber 9 and contacts the outer surface of the first spiral coil 901 to cool down and then condenses water. Hydrophobic coatings are applied on the inner wall of the cyclone chamber 9 and the outer wall of the first spiral coil 901. A group of orderly arranged conical protrusions are also added on the inner wall of the cyclone chamber 9, which is more conducive to the sliding of water droplets. A cold air inlet 902, a moist air inlet 903, an exhaust gas outlet 904 and a water outlet are arranged on the cyclone chamber 9. The air outlet of the blower 5 is connected to the moist air inlet 903 of the cyclone chamber 9. The air pressurized by the blower 5 flows tangentially into the cyclone chamber 9 through the moist air inlet 903, contacts the outer surface of the first spiral coil 901 to cool down and then condenses water, and the gas-liquid separation is carried out by using the centrifugal force generated by the rotating air flow. The air suction port 501 of the blower 5 is connected to the underground air inlet passage, aiming to extract the moisture in the soil. The underground air inlet passage consists of three parts: a straight shaft 502, a horizontal well 503 and a conical frustum shaft 504. The underground passage inlet 505 adopts a shutter and is provided with an umbrella-shaped wind cap to prevent the intrusion of sand and impurities. The depth of the horizontal well 503 should be greater than the local maximum frost depth. The taper of the conical frustum shaft should ensure that a certain suction force can be generated. In order to increase the permeability of soil moisture, blind holes 506 are added on the wall of the underground air inlet passage. Normal temperature air exchanges heat and moisture with the moisture in the soil in the underground air inlet passage and then enters the air suction port 501 of the blower 5 through the gas transmission pipeline.

[0044] A humidifier 11 is arranged on the connecting pipeline between the blower 5 and the cyclone chamber 9. Normal temperature air exchanges heat and moisture with the moisture in the soil through the underground air inlet passage. The humidified moist air flows tangentially into the cyclone chamber 9 through the blower 5 and the gas transmission pipeline, and a part of the condensed water will be precipitated after contacting the outer surface of the spiral pipe and cooling down.

[0045] The air compressor 4 is sequentially connected to the cold air inlet 902 of the cyclone chamber 9 through an air storage tank 6 and a vortex tube 8. The purpose of the air storage tank 6 is to reduce the starting times of the compressor and reduce the influence of the air flow pulsation in the gas transmission pipeline on the system operation. The design pressure of the air storage tank 6 is 8 kg, and the wall thickness and strength design should be strictly implemented in accordance with the national standards for pressure vessels. In order to better collect the compression heat generated during the compression process, an inner and outer double-ring second spiral coil 605 is arranged inside the air storage tank 6. A semi-circular baffle 606 is arranged in the middle of the second spiral coil 605, aiming to organize the air flow and ensure full heat exchange between gas and liquid.

[0046] The air storage tank 6 is provided with a compressed air inlet 601, a compressed air outlet 602, a first circulating medium inlet 603 and a first circulating medium outlet 604. The two ends of the second spiral coil 605 are respectively connected to the first circulating medium inlet 603 and the first circulating medium outlet 604. The circulating medium flows in from the first circulating medium inlet 603 and then enters the outer ring second spiral coil 605 and the inner ring second spiral coil 605 respectively. The circulating medium exchanges heat with the high-temperature compressed air, and the collected compressed heat converges into the heat storage tank 7 through the heat collection branch. A pressure relief valve interface and a pressure gauge interface are also provided on the air storage tank 6 for adjusting the internal air pressure.

[0047] The air compressor 4 is connected to the air storage tank 6 through a 304 stainless steel corrugated hose, which is convenient for installation and shock absorption. In order to ensure water quality, an oil-free model is selected; in order to extend the service life and reduce the manufacturing cost, an air compressor 4 with lubricating oil is selected, and an oil-gas separator is added between the air storage tank 6 and the vortex tube 8; the air pressurized by the air compressor 4 is stored in the air storage tank 6. The compressed air in the air storage tank 6 forms low-temperature cold air after passing through the vortex tube 8, flows into the swirl chamber 9 through the cold air inlet 902, and the cold air entering the first spiral coil 901 flows in the first spiral coil 901 to form a cold source lower than the local air dew point temperature. In this process, the compressed air in the air storage tank 6 is sprayed tangentially into the interior of the vortex tube 8 from the inlet of the vortex tube 8, and the high-speed rotating air flow separates the high-temperature air flow on the outer side and the low-temperature air flow on the inner side with opposite flow directions. The temperature of the low-temperature air flow can be adjusted by the flow regulating valve at the high-temperature exhaust end, and the lowest temperature of the cold air can reach -46°C. The vortex tube 8 has the advantages of small volume, low cost, no moving parts, maintenance-free, and fast adjustment response speed.

[0048] In this embodiment, the air condensation water production device is arranged in a cross shape. The air compressor 4 is at the upper left, the water storage tank 10 is at the lower left, the air storage tank 6 is at the upper right, the heat storage tank 7 is at the lower right, and the swirl chamber 9 is placed in the middle. The fan 5 and the water pump 12 are respectively installed on both sides of the swirl chamber 9. When arranging the equipment, it should be arranged as compactly as possible on the basis of ensuring enough maintenance space. In order to extend the service life of the air condensation water production device, the air condensation water production device should be placed in a container, a building or a special machine room.

[0049] The exhaust gas outlet 904 of the cyclone chamber 9 is connected to the soot blowing pipeline. Two nozzles 16 are arranged on the soot blowing pipeline, and the two nozzles 16 are respectively arranged at the upper ends of the solar photovoltaic module 2 and the flat plate collector 3. The exhaust gas flowing out of the cyclone chamber 9 is used to blow the sand and dust on the solar photovoltaic module 2 and the flat plate collector 3 after passing through the soot blowing pipeline, improving the utilization rate of components and the reliability of the system. When there is floating soil or sand and dust on its surface, the soot blowing mode is started by opening the third solenoid valve. A fan-shaped air flow is formed at the outlet of the nozzle 16, and the surfaces of the solar photovoltaic panel 2 and the flat plate collector 3 are kept clean by air blowing, improving the utilization rate of components.

[0050] The drain outlet 905 of the cyclone chamber 9 is connected to the water storage unit. The condensed water precipitated in the cyclone chamber 9 is discharged through the drain outlet 905 and collected into the water storage tank 10 via the water collecting pipeline. The water storage unit is set as the water storage tank 10. The water inlet of the water storage tank 10 is connected to the gas storage tank 6. A part of the condensed water will also be generated after the compressed air in the gas storage tank 6 is cooled, and it also flows into the water storage tank 10 through the water collecting pipeline.

[0051] The water storage tank 10 is connected to the water supply unit. The water supply unit is provided with a water pump 12, a filter 13 and an ultraviolet disinfection device 14. One end of the water pump 12 is connected to the water outlet of the water storage tank 10. The other end of the water pump 12 is connected with a first solenoid valve 17 and a second solenoid valve 18. The water pump 12 is sequentially connected with the filter 13 and the ultraviolet disinfection device 14 through the first solenoid valve 17. The water pump 12 is connected to the heat storage unit through the second solenoid valve 18. The water outlet of the heat storage unit is sequentially connected with the filter 13 and the ultraviolet disinfection device 14. When the user has a water demand, the water pump 12 pumps the condensed water from the water storage tank 10, opens the first solenoid valve 17, and closes the second solenoid valve 18 at the same time. The condensed water is pressurized and then processed by the filter 13 and the ultraviolet disinfection device 14 to provide agricultural water or domestic water for the user. When the user has a hot water demand, the first solenoid valve 17 is closed and the second solenoid valve 18 is opened at the same time. The condensed water absorbs heat in the heat storage unit and then supplies it to the user. The supply water temperature is controlled by the opening degree of the second solenoid valve 18.

[0052] The heat storage unit is set as the heat storage tank 7. The heat storage tank 7 is connected to the gas storage tank 6 and the flat plate collector 3. The solar energy collected in the flat plate collector 3 and the compressed heat collected in the gas storage tank 6 are stored in the heat storage tank. At night or in certain specific situations, domestic hot water is provided for the user. The heat generated during the operation of the compressor is transferred to the circulating medium in the gas storage tank 6 and then converges to the heat storage tank 7 through the heat collecting branch. The heat collecting branches are connected in parallel.

[0053] The heat storage tank 7 stores a heat storage liquid 701 and heat storage balls 702. The heat storage liquid 701 is an inorganic salt solution, and the material of the heat storage balls 702 is a nano zinc / paraffin composite phase change heat storage material;

[0054] An overflow pipe 703 is provided at the top of the heat storage tank 7, and a drain port 704 is provided at the bottom. A second circulating medium inlet 705, a second circulating medium outlet 706, a water supply heating inlet 707, and a water supply heating outlet 708 are provided on the side wall of the heat storage tank 7. A horizontally arranged third spiral coil pipe 710 and a vertically arranged S-shaped coil pipe 709 are arranged inside the heat storage tank 7. The third spiral coil pipe 710 is arranged outside the S-shaped coil pipe 709. Both ends of the S-shaped coil pipe 709 are respectively connected to the water supply heating inlet 707 and the water supply heating outlet 708. Both ends of the spiral coil pipe are respectively connected to the second circulating medium inlet 705 and the second circulating medium outlet 706. The second circulating medium inlet 705 is connected to the heat storage medium circulation pump 15 for transporting the circulating medium. The circulating medium after absorbing solar heat and compression heat enters the spiral coil pipe through the second circulating medium inlet 705, transfers the heat to the heat storage liquid 701 and the heat storage balls 702, and then returns to the suction port of the heat storage medium circulation pump 15;

[0055] A circular baffle 711 is provided at the upper end of the third spiral coil pipe 710 inside the heat storage tank 7 to prevent the heat storage balls 702 from floating upward due to heat and blocking the overflow pipe 703. A plurality of openings are provided on the circular baffle 711. The openings are arranged in a circumferential manner, and the aperture diameters are arranged in a form of decreasing sequentially from large in the middle to small at the edge along the radial direction. The maximum diameter of the central opening is the diameter of the heat storage balls 702, and the diameter of the edge opening should ensure that the heat storage liquid 701 can flow freely.

[0056] When the user has a hot water demand, the condensed water is pressurized and sent to the water supply heating inlet 707 of the heat storage tank, and after absorbing the heat of the heat storage liquid 701 through the S-shaped coil pipe 709, it is supplied to the user after being processed by the filter 13 and the ultraviolet disinfection device 14. In order to prevent heat loss, a sufficiently thick heat insulation layer is added to the outer wall surface of the heat storage tank.

[0057] In the above device, a third solenoid valve is installed on each pipeline according to actual needs, such as at the drain port of the cyclone chamber, between the blowing pipeline and the nozzle, etc.

[0058] The control strategy of the above device is as follows: Under the inlet air state, the values measured by the temperature sensor and the relative humidity sensor at the outlet position of the fan 5 are used to find the corresponding state point on the enthalpy-humidity diagram h-d, and the corresponding dew point temperature is obtained through calculation. By adjusting the opening degree of the flow regulating valve of the vortex tube 8, it is ensured that the average temperature of the spiral coil pipe inside the cyclone chamber 9 is lower than the dew point temperature corresponding to the inlet air state. When the relative humidity of the inlet air state is lower than 10%, the humidifier 11 is started to humidify the humid air at constant enthalpy. The start and stop of the air compressor 4 are determined by the set value of the differential pressure switch. The electricity generated by the wind turbine 1 and the solar photovoltaic module 2 is converted into 220V alternating current through the inverter and provides power for this device.

[0059] Therefore, an air condensation water production system powered by wind-solar hybrid in the present invention makes full use of renewable resources such as wind, light, and heat, and uses the principle of air condensation to provide a device for collecting water vapor in surface air and soil moisture in the ground for islands and arid areas lacking fresh water resources, so as to solve agricultural and domestic water use and improve the local ecological and living environments.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
