Description

Technical Field

[0002] Ocean-going ships need to carry hundreds of tons of fresh water when sailing. The water quality cannot be guaranteed during long voyages. The use of seawater desalination technology is an effective freshwater supplement technology, but it consumes a lot of fuel. my country's South China Sea islands are surrounded by the sea. Under the influence 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 and rivers and lakes, water resources have become extremely precious. In order to solve the problem of water shortage in water-scarce areas, people have invented air-to-water technology, which can "take water" from the air, that is, using an air-to-water machine. Its working principle is to exchange heat between the air and the evaporator in the refrigeration system, reduce the air temperature to below the dew point, condense the water vapor in the air, and convert it into water resources, which becomes domestic water, agricultural water, and emergency water sources.

[0003] In the prior art, air water generators are used to make water in high temperature areas, but most of the machines require a refrigeration system. The direct heat exchange between the outdoor air and the evaporator results in a very low evaporation temperature setting value, which is -5°C to -20°C. The compressor operates in poor conditions and has a very low COP. Most of them focus on collecting water vapor in the air.

A flat plate collector 3 is connected to the power generation device for collecting solar heat. The solar photovoltaic module 2 is fixed to the tower of the wind turbine 1 through a bracket. Wind power generation and the solar photovoltaic module 2 provide green electricity for the device after inversion. A battery can be set to store electrical energy. In the specific setting, the tower of the wind turbine 1 is the center, and the solar photovoltaic module 2 and the flat plate collector 3 are arranged in the south, and the air condensation water making device is arranged in the north. The flat plate collector 3 is installed with a fixed bracket with the best local inclination angle. The bracket is installed on the reinforced concrete pile foundation on the ground.

Before sunrise and after sunset, the heat collection branch where the flat plate collector is located is kept in a closed state by closing the solenoid valve. The solar photovoltaic module 2 is composed of multiple polycrystalline silicon photovoltaic panels, and its bracket is fixed to the tower of the wind turbine 1.

The wind turbine 1 uses a horizontal axis three-blade upwind form, and the wind turbine 1 is automatically facing the wind through a variable pitch system.

[0027] The water production unit includes an air compressor 4, a fan 5 and a cyclone chamber 9. The cyclone chamber 9 adopts a cyclone separator, which is a commonly used equipment for dust purification in the industrial field. The upper part of the cyclone chamber 9 is set as a cylindrical structure for tangential air intake, the middle part is set as a reduced truncated cone structure with a large upper part and a small lower part, and the lower part is set as a cylindrical water collection cavity structure. In order to strengthen the heat exchange between cold and hot gases, the interior of the cyclone chamber 9 is provided with a first spiral coil 901, which is similar to the outer contour of the cyclone chamber 9 and is proportionally reduced. The inner wall of the first spiral coil 901 adopts a micro-rib structure, and the cold air flows in the tube to form a cold source. The wet air enters the cyclone chamber 9 and contacts the outer surface of the first spiral coil 901 to cool down and condensate water is precipitated. The inner wall of the cyclone chamber 9 and the outer wall of the first spiral coil 901 are both painted with hydrophobic coatings, and a group of orderly arranged conical protrusions are also added to the inner wall of the cyclone chamber 9, which is more conducive to the water droplets sliding down. The cyclone chamber 9 is provided with a cold air inlet 902, a wet air inlet 903, an exhaust air outlet 904 and a water outlet. The air outlet of the fan 5 is connected to the wet air inlet 903 of the cyclone chamber 9. The pressurized air of the fan 5 flows into the cyclone chamber 9 tangentially through the wet air inlet 903, and condenses after contacting with the outer surface of the first spiral coil 901 for cooling. The condensed water is precipitated, and the centrifugal force generated by the rotating airflow is used for gas-liquid separation. The air inlet 501 of the fan 5 is connected to the underground air inlet channel for the purpose of extracting moisture from the soil. The underground air inlet channel consists of three parts: a straight shaft 502, a horizontal shaft 503 and a truncated cone tapered shaft 504. The underground channel entrance 505 adopts shutters and is provided with an umbrella-shaped wind cap to prevent the intrusion of wind and sand impurities. The depth of the horizontal well 503 should be greater than the local maximum frozen soil depth. The taper of the tapered cone 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 channel. Normal temperature air exchanges heat and moisture with the moisture in the soil in the underground air inlet channel and then enters the air inlet 501 of the fan 5 through the air pipeline.

[0028] A humidifier 11 is provided on the connecting pipeline between the fan 5 and the cyclone chamber 9. The air at normal temperature exchanges heat and moisture with the moisture in the soil through the underground air inlet channel. The humidified air flows tangentially into the cyclone chamber 9 through the fan 5 and the air pipeline, and some condensed water is precipitated after being cooled by contact with the outer surface of the spiral tube.

[0029] The air compressor 4 is connected to the cold air inlet 902 of the cyclone chamber 9 through the air tank 6 and the vortex tube 8 in sequence. The purpose of the air tank 6 is to reduce the number of startups of the compressor and reduce the impact of the air flow pulsation of the gas pipeline on the operation of the system. The design pressure of the air 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, the interior of the air tank 6 is provided with a second spiral coil 605 with inner and outer double circles, and a semicircular baffle 606 is provided in the middle of the second spiral coil 605, the purpose of which is to organize the airflow and ensure sufficient heat exchange between gas and liquid.

[0030] 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 into the outer second spiral coil 605 and the inner second spiral coil 605 after flowing from the first circulating medium inlet 603. The circulating medium exchanges heat with the high-temperature compressed air, and the collected compression heat is converged into the heat storage tank 7 via the heat collection branch. The air storage tank 6 is also provided with a pressure relief valve interface and a pressure gauge interface for adjusting the internal air pressure.

[0031] The air compressor 4 is connected to the air tank 6 through a 304 stainless steel bellows hose, which is convenient for installation and shock absorption. In order to ensure the water quality, an oil-free model is selected; in order to extend the service life and reduce the manufacturing cost, the air compressor 4 is selected as a model with lubricating oil, and an oil-gas separator is added between the air tank 6 and the vortex tube 8; the air pressurized by the air compressor 4 is stored in the air tank 6, and the compressed air in the air tank 6 forms low-temperature cold air after passing through the vortex tube 8, flows into the cyclone 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 tank 6 is sprayed into the vortex tube 8 from the inlet of the vortex tube 8 along the tangential direction, and the high-speed rotating airflow separates the high-temperature airflow on the outside and the low-temperature airflow on the inside with opposite flow directions. The temperature of the low-temperature airflow 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 size, low cost, no moving parts, maintenance-free, fast adjustment response speed, etc.

[0032] In this embodiment, the air condensation water making device is arranged in a field shape, with the air compressor 4 on the upper left, the water storage tank 10 on the lower left, the gas storage tank 6 on the upper right, the heat storage tank 7 on the lower right, and the cyclone chamber 9 in the center. The fan 5 and the water pump 12 are respectively installed on both sides of the cyclone chamber 9. When arranging the equipment, it is arranged as compactly as possible on the basis of ensuring that sufficient maintenance space is reserved. In order to extend the service life of the air condensation water making device, the air condensation water making device should be placed in a container, a building or a special machine room.

[0033] The exhaust gas outlet 904 of the cyclone chamber 9 is connected to the soot blowing pipeline, and 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 passes through the soot blowing pipeline and is used to blow away the sand and dust on the solar photovoltaic module 2 and the flat plate collector 3, thereby improving the utilization rate of the components and the reliability of the system. When there is loose soil or sand on the surface, the soot blowing mode is turned on by the third solenoid valve, and a fan-shaped airflow is formed at the outlet of the nozzle 16. The surface of the solar photovoltaic panel 2 and the flat plate collector 3 is kept clean by air blowing, thereby improving the utilization rate of the components.

[0034] 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 tank 10 via the water collecting pipeline. The water storage unit is set as the water tank 10. The water inlet of the water tank 10 is connected to the air tank 6. After the compressed air in the air tank 6 is cooled, a part of condensed water will also be generated, which also flows into the water tank 10 via the water collecting pipeline.

[0035] The water storage tank 10 is connected to the water supply unit, which 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, and the other end of the water pump 12 is connected to the first solenoid valve 17 and the second solenoid valve 18. The water pump 12 is connected to the filter 13 and the ultraviolet disinfection device 14 in sequence through the first solenoid valve 17, and 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 connected to the filter 13 and the ultraviolet disinfection device 14 in sequence. When the user has a water demand, the water pump 12 extracts 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. After the condensed water is pressurized, it is 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 is supplied to the user. The water supply temperature is controlled by the opening of the second solenoid valve 18.

[0036] The heat storage unit is configured as a heat storage tank 7, which 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 compression heat collected in the gas storage tank 6 are stored in the heat storage tank, providing domestic hot water for users at night or in certain specific situations. The heat generated during the operation of the compressor is transferred to the circulating medium in the gas storage tank 6 and then converged to the heat storage tank 7 via the heat collection branch. The heat collection branches are connected in parallel.

[0037] The heat storage tank 7 stores 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. An overflow pipe 703 is provided at the top of the heat storage tank 7, and a sewage outlet 704 is provided at the bottom. A second circulating medium inlet 705, a second circulating medium outlet 706, a water supply and heating inlet 707 and a water supply and heating outlet 708 are provided on the side wall of the heat storage tank 7. A third spiral coil 710 arranged horizontally and an S-shaped coil 709 arranged longitudinally are provided inside the heat storage tank 7. The third spiral coil 710 is arranged outside the S-shaped coil 709. Both ends of the S-shaped coil 709 are respectively connected to the water supply and heating inlet 707 and the water supply and heating outlet 708. Both ends of the spiral coil 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 conveying the circulating medium. The circulating medium after absorbing the solar energy heat and the compression heat enters the spiral coil through the second circulating medium inlet 705, transfers the heat to the heat storage liquid 701 and the heat storage ball 702, and then flows back to the suction port of the heat storage medium circulation pump 15. A circular baffle 711 is provided at the upper end of the third spiral coil 710 inside the heat storage tank 7, the purpose of which is to prevent the heat storage ball 702 from floating up and blocking the overflow pipe 703 due to heat; a plurality of openings are provided on the circular baffle 711, the openings are arranged in a circle, and the apertures are arranged in a radially decreasing manner with the largest aperture in the middle and the smallest apertures at the edges. The maximum diameter of the central opening is the diameter of the heat storage ball 702, and the diameter of the edge openings should ensure that the heat storage liquid 701 can flow freely.

[0038] When the user needs hot water, the condensed water is pressurized and sent to the water supply and heating inlet 707 of the heat storage tank. After the S-shaped coil 709 absorbs the heat of the heat storage liquid 701, it is processed by the filter 13 and the ultraviolet disinfection device 14 and then supplied to the user. In order to prevent heat loss, a sufficiently thick insulation layer is added to the outer wall of the heat storage tank.

[0039] In the above device, a third solenoid valve is installed on each pipeline according to actual needs, such as at the drain outlet of the cyclone chamber, between the blowing pipeline and the nozzle, etc.

[0040] The control strategy of the above device is: the values ​​measured by the temperature sensor and relative humidity sensor at the outlet of the fan 5 in the air intake state find the corresponding state point on the enthalpy-humidity diagram hd, and the corresponding dew point temperature is obtained by calculation. By adjusting the opening of the flow regulating valve of the vortex tube 8, the average temperature of the spiral coil inside the cyclone chamber 9 is ensured to be lower than the dew point temperature corresponding to the air intake state. When the relative humidity content in the air intake state is lower than 10%, the humidifier 11 is started to humidify the wet air with isenthalpy. The start and stop of the air compressor 4 is determined by the set value of the pressure difference switch. The electricity generated by the wind turbine 1 and the solar photovoltaic module 2 is converted into 220V AC power by the inverter to provide power for this device.

[0041] Therefore, the air condensation water production system with wind-solar complementary power supply of the present invention makes full use of renewable resources such as wind, light, and heat, and uses the principle of condensation when air is cold to provide a device for collecting surface air water vapor and underground soil moisture for islands and arid areas that lack fresh water resources, thereby solving agricultural and domestic water problems and improving the local ecological environment and living environment.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
