Description

Technical Field

[0001] The present invention relates to the field of water production from air, and in particular to a water production device for obtaining liquid water from air through the cooperation of an air compressor, a rotary dehumidifier and a vortex tube. Background Art

[0002] As a new type of clean water extraction method, air-to-water has attracted worldwide attention. It has been widely used in water-scarce areas of the world. It can solve the drinking water problem in areas lacking surface water and groundwater, and is the development direction of comprehensive utilization of energy and resources in the future. At present, there are two main methods for making water from the air, one is compressor condensation water production, and the other is rotary dehumidifier water production. The two water production methods have their own advantages and disadvantages. Compressor condensation water production cannot produce water from the air when the ambient temperature and humidity are low; the power consumption of the rotary dehumidifier is relatively large. The main energy consumption of the rotary dehumidifier is used to heat the regeneration air inlet air and flow out from the regeneration air outlet. The waste heat of the hot air at the regeneration air outlet cannot be recycled, and the comprehensive energy efficiency is not high. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new type of composite water production device, which can realize the function of producing liquid water from the air under low temperature and low humidity conditions, and is suitable for water production in arid and low temperature areas.

[0004] In order to solve the above technical problems, the present invention provides a novel composite water production device;

[0005] It includes a rotary dehumidifier, an air compressor, a vortex tube, a centrifugal fan, a heat-insulating liquid storage tank and at least one set of recovery components;

[0006] The recovery assembly includes a gas storage tank, a heat dissipation duct and at least one heat pipe, one end of the heat pipe extends into the gas storage tank, and the other end of the heat pipe extends into the heat dissipation duct;

[0007] The rotary dehumidifier is provided with an air inlet, an air outlet, an exhaust port and a return port, the air inlet of the rotary dehumidifier is communicated with the external atmosphere, the exhaust port of the rotary dehumidifier is communicated with the inlet of the air compressor, the outlet of the air compressor is communicated with the inlet of the air storage tank of the recovery component, the outlet of the air storage tank of the recovery component is communicated with the inlet of the vortex tube, the hot air outlet of the vortex tube is communicated with the return port of the rotary dehumidifier, and the cold air outlet of the vortex tube is communicated with the inlet of the thermal insulation liquid storage tank;

[0008] The bottom of the gas storage tank of the recovery component is connected to the heat preservation liquid storage tank through a pipeline, and the horizontal height of the bottom of the gas storage tank of the recovery component is higher than the horizontal height of the upper end of the heat preservation liquid storage tank;

[0009] The inlet of the centrifugal fan is connected to the outlet of the heat preservation liquid storage tank, the outlet of the centrifugal fan is connected to the inlet of the heat dissipation air duct of the recovery component, and the outlet of the heat dissipation air duct of the recovery component is also connected to the reflux port of the rotary dehumidifier.

[0010] After adopting such a structure, the new composite water-making device can produce water in a low-temperature and low-humidity environment. The rotary dehumidifier converts low-temperature and low-humidity air into high-temperature and high-humidity air, effectively raising the dew point temperature of the air; the recovery component works in a continuous cycle according to a control sequence, so that the system composed of the air compressor and the recovery component can work continuously around the clock, compressing air, precipitating condensed water and discharging condensed water.

[0011] The vortex tube can significantly cool the air cooled by the heat pipe to a dew point temperature much lower than that of the traditional water maker, for example, -10℃ to -40℃ (the dew point temperature of the compressor water maker is 0℃, and the dew point temperature of the rotary water maker is -10℃). The only small amount of water vapor in the air can be separated in the form of droplets or frost and collected in an insulated liquid storage tank.

[0012] The water condensed in the air tank of the recovery component and the compressed air pass through the vortex tube to produce condensed water or frost, which becomes the total amount of water produced from the air by the new composite water-making device; at the same time, the vortex tube converts high-pressure air energy into low-temperature air energy and high-temperature thermal energy. The low-temperature air energy is used for cooling the air tank, and the high-temperature thermal energy is used as the regenerative heat source of the rotary dehumidifier, thereby improving the utilization rate of energy and the overall efficiency of the equipment; low-temperature water is stored to ensure water quality.

[0016] A first electromagnetic air valve is provided on the pipeline between the air storage tank inlet and the air compressor outlet of each recovery component of the novel composite water production device, a second electromagnetic air valve is provided on the pipeline between the air storage tank outlet of the recovery component and the vortex tube inlet, and an electromagnetic water valve is provided on the pipeline between the bottom of the air storage tank of the recovery component and the insulation liquid storage tank.

The outlet of the gas mixer is connected to the return port of the rotary dehumidifier, and the three inlets of the gas mixer are respectively connected to the hot air outlet of the vortex tube, the heat dissipation duct outlets of all recovery components and the air outlet of the rotary dehumidifier.

[0019] After adopting such a structure, the gas mixer is used to mix the high-temperature gas from the vortex tube, the high-temperature gas from the heat dissipation duct, and the air from the environment, mix the gas to a specified temperature and flow rate, and provide it to the rotary dehumidifier for water regeneration hot gas source.

[0020] The air outlet of the rotary dehumidifier is provided with an air volume proportional distributor, and the air outlet of the rotary dehumidifier is communicated with the inlet of the gas mixer through the air volume proportional distributor.

[0021] After adopting such a structure, the air intake volume at the inlet of the air volume proportional distributor gas mixer meets the use requirements of the rotary dehumidifier.

[0022] A guide pipe is inserted into the heat-insulating liquid storage tank of the novel composite water-making device, and the guide pipe guides the water flowing out of the cold end of the vortex tube to flow out continuously and realizes the separation of gas and liquid.

[0025] like Figures 1 to 2 Shown

[0026] The novel composite water production device comprises a rotary dehumidifier 1, an air compressor 2, a vortex tube 4, a centrifugal fan 7, a gas mixer 5, an air volume proportional distributor 8, a heat preservation liquid storage tank 6 and three sets of recovery components 3.

[0027] The rotary dehumidifier 1 is provided with an air inlet 11, an air outlet 12, an exhaust port 13 and a reflux port 14. The air inlet 11 of the rotary dehumidifier 1 is communicated with the external atmosphere. The rotary dehumidifier 1 absorbs moisture from the air, converts low-humidity air into high-humidity air, and increases the water content in the air. The exhaust port 13 of the rotary dehumidifier 1 is communicated with the inlet of the air compressor 2 to provide an air source for the air compressor 2.

[0028] The recovery component 3 includes an air storage tank 31 , a heat dissipation duct 32 and three heat pipes 33 . One end of the heat pipe 33 extends into the air storage tank 31 , and the other end of the heat pipe 33 extends into the heat dissipation duct 32 .

[0029] The inlets of the air storage tanks 31 of the three recovery components 3 are respectively connected to the outlets of the air compressor 2, and the outlets of the air storage tanks 31 of the three recovery components 3 are respectively connected to the inlets of the vortex tube 4, so as to achieve the purpose of connecting the air storage tanks 31 of the three recovery components 3 in parallel between the air compressor 2 and the vortex tube 4; similarly, the inlets of the heat dissipation ducts 32 of the three recovery components 3 are respectively connected to the outlets of the centrifugal fans 7, and the outlets of the heat dissipation ducts 32 of the three recovery components 3 are connected to one of the three inlets of the gas mixer 5.

[0030] The bottoms of the gas storage tanks 31 of the three recovery components 3 are connected to the thermal insulation liquid storage tank 6 through pipelines, and the horizontal height of the bottom of the gas storage tank 31 of the recovery component 3 is higher than the horizontal height of the upper end of the thermal insulation liquid storage tank 6.

[0031] A first solenoid valve 34 is provided on the pipeline between the inlet of the air storage tank 31 of each recovery component 3 and the outlet of the air compressor 2, a second solenoid valve 35 is provided on the pipeline between the outlet of the air storage tank 31 of each recovery component 3 and the inlet of the vortex tube 4, and an solenoid water valve 36 is provided on the pipeline between the bottom of the air storage tank 31 of each recovery component 3 and the insulation liquid storage tank 6.

[0032] The hot air outlet 41 of the vortex tube 4 is connected to one of the three inlets of the gas mixer 5 , the cold air outlet 42 of the vortex tube 4 is connected to the inlet of the thermal insulation liquid storage tank 6 , and the inlet of the centrifugal fan 7 is connected to the outlet of the thermal insulation liquid storage tank 6 .

[0033] The vortex tube 4 converts the pressure energy of compressed air into high-temperature air energy and low-temperature air energy (heat energy separation). The low-temperature air and the high-temperature air are discharged from the cold air outlet 42 and the hot air outlet 41 of the vortex tube 4 respectively. The low-temperature air instantly reaches the air dew point and condenses water at the cold air outlet 42 and is discharged into the thermal insulation liquid storage tank 6. At the same time, the discharged high-temperature air is used for the high-temperature regeneration air required by the rotary dehumidifier 1, and the discharged low-temperature air is used to cool the gas storage tank 31.

[0034] The centrifugal fan 7 leads the cold air in the insulated liquid storage tank 6 to the heat pipe 33 at high speed for heat exchange, and takes away the air heat in the gas storage tank 31 through the heat pipe 33, thereby cooling the air in the gas storage tank 31 and promoting the precipitation of part of the condensed water from the hot and humid air in the gas storage tank 31. At the same time, the regenerated air of the rotary dehumidifier 1 also provides part of the heat, thereby improving the comprehensive energy utilization efficiency of the water production system.

[0035] The inlet of the air volume proportional distributor 8 is connected to the air outlet 12 of the rotary dehumidifier 1, and one outlet of the air volume proportional distributor 8 is connected to one of the three inlets of the gas mixer 5. One outlet of the air volume proportional distributor 8 discharges the dry air discharged from the rotary dehumidifier 1 normally.

[0036] A guide pipe 61 is inserted into the heat-insulating liquid storage tank 6 to guide the water flowing out of the cold end of the vortex tube 4 to flow out continuously and realize the separation of gas and liquid. The guide pipe 61 guides the water flowing out of the cold end of the vortex tube 4 in an orderly manner to avoid splashing of droplets.

[0037] The gas mixer 5 includes an outlet and three inlets. The outlet of the gas mixer 5 is connected to the reflux port 14 of the rotary dehumidifier 1. The three inlets of the gas mixer 5 are respectively connected to the hot air outlet 41 of the vortex tube 4, the heat dissipation duct 32 outlets of all recovery components 3 and the air outlet 12 of the rotary dehumidifier 1.

[0038] At the same time, among the three groups of recovery components 3, only the first solenoid valve 34 of one group of recovery components 3 is opened, and the recovery component 3 with the first solenoid valve 34 opened is in the inflation working state; the second solenoid valve 35 and the solenoid water valve 36 of the other group of recovery components 3 are opened, the air in the gas storage tank 31 of the recovery component 3 flows through the vortex tube 4, and the condensed water in the gas storage tank 31 of the recovery component 3 flows into the heat-insulating liquid storage tank 6, and the recovery component 3 is in the deflation working state; the first solenoid valve 34, the second solenoid valve 35 and the solenoid water valve 36 of the last group are all closed, and only the heat pipe 33 is used to exchange heat between the air in the gas storage tank 31 and the air in the heat dissipation duct 32, and the recovery component 3 is in the heat exchange working state.

[0039] Furthermore, when the pressure in the gas tank 31 of the recovery component 3 in the deflation working state reaches the set pressure, the second electromagnetic valve 35 connected between the gas tank 31 and the vortex tube 4 is closed, and the electromagnetic water valve 36 is correspondingly closed, the gas tank 31 is no longer deflated, and the first electromagnetic valve 34 is opened, and the recovery component 3 is immediately in the inflation working state; the second electromagnetic valve 35 and the electromagnetic water valve 36 of the recovery component 3 that were originally in the heat exchange working state are opened, and the recovery component 3 is in the deflation working state; when the pressure in the gas tank 31 of the recovery component 3 in the inflation working state reaches the set pressure, the first electromagnetic valve 34 is closed, and the recovery component 3 is in the heat exchange working state;

[0040] The three recovery components 3 work repeatedly, and each recovery component 3 cycles to prepare for the next working state. It is well known that engineers and technicians in this field can select system parameters to meet the matching relationship of this working cycle.

[0041] The high-pressure air flowing out of the recovery component 3 flows through the vortex tube 4 and is discharged at both ends. The cold air at the cold air outlet 42 of the vortex tube 4 passes through the heat preservation liquid storage tank 6, the centrifugal fan 7, and the heat dissipation duct 32 until it enters the inlet of the gas mixer 5 and becomes high-temperature gas at the same time; the hot air at the hot air outlet 41 of the vortex tube 4 enters the inlet of the gas mixer 5, and the gas mixer 5 mixes the gases at the three inlets into high-temperature gas at a specified temperature. The high-temperature gas provides a high-temperature regeneration air source for the rotary dehumidifier 1, and the air intake at the inlet of the air volume proportional distributor 8 gas mixer 5 meets the equipment use requirements;

[0042] The external control system 9 can also simultaneously control the air volume proportional distributor 8, the rotary dehumidifier 1, the air compressor 2, the first electromagnetic air valve 34, the second electromagnetic air valve 35, and the electromagnetic water valve 36 to complete the system's working cycle.

[0043] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as falling within the scope of protection of the present invention.
