Description

Technical Field

[0001] The present invention relates to the technical field of water collection, and in particular to a method for producing water by utilizing deep-sea low-temperature water and a high-efficiency water production system thereof. Background Art

[0002] With the increase of population and economic development, the global fresh water resources are becoming increasingly scarce. Less than 1% of the water resources on earth are shared by humans, plants and animals, and humans are still continuously polluting the limited water resources. In the next 10 years, if no new fresh water resources are found, two-thirds of the people on earth will face water shortage.

[0003] At present, seawater desalination technology is widely used to obtain fresh water from seawater. However, the application and popularization of seawater desalination are restricted by the complex equipment, huge investment, the need to replace the filter element during use, and the difficulty in completely removing the salt in the water.

[0004] Condensation water production is one of the traditional water collection technologies. This technology uses a compressor to refrigerate, and the refrigeration pipe conducts the low temperature to the fins. When the difference between the fin surface temperature and the ambient temperature reaches the dew point, water droplets are formed and water is obtained. However, there are two problems with the current condensation water production technology:

[0005] First, the commonly used refrigerants (such as R304a, R410a, R407c, etc.) are expensive and cause environmental pollution. After using deep sea low temperature water, the cost is greatly reduced due to the absence of refrigerants, and zero pollution to the environment is achieved.

[0006] Second, when using the traditional fin condensation method, the contact area between the air and the fin is only the flat surface area, and the water production efficiency is not high. After adopting the honeycomb refrigeration tube structure, the contact area between the water collecting pipe and the air is greatly increased, achieving efficient water production.

[0007] After using adsorption surface materials and surface optimization treatment, the contact area between the water collection pipe surface and the air is further increased. At the same time, the water absorption of the adsorption material and the hydrophilicity of the surface treatment technology are utilized to solve the problem of maintaining the system function of efficient water production under environmental conditions with low temperature and humidity and reduced condensation efficiency.

[0008] The technology and system of the present invention will comprehensively improve water production efficiency, reduce energy consumption, and avoid environmental pollution. The resulting system equipment will gradually replace seawater desalination equipment and become a disruptive technology and equipment for marine environment water collection. Summary of the invention

[0009] In view of the deficiencies in the prior art, the present invention provides a method for producing water using low-temperature deep-sea water and an efficient water production system thereof, which solves the technical problems raised in the above-mentioned background technology.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for producing water source using deep-sea low-temperature water and an efficient water production system thereof, including a method for producing water source using deep-sea low-temperature water and an efficient water production system, the method for producing water source using deep-sea low-temperature water, the method comprising the following steps:

[0011] A: Prepare floating dock, pressure-resistant heat-insulating pipe, high-pressure self-priming pump, high-efficiency water collector, purifier, water storage tank, water collecting tank and circulating water pump, and extend the pressure-resistant heat-insulating pipe into the deep-sea low-temperature water area;

[0012] B: Use a high-pressure self-priming pump to pump deep-sea low-temperature water into a high-efficiency water collector;

[0013] C: The seawater entering the high-efficiency water collector flows into the refrigeration pipes, which are evenly distributed at the connection between each water collector and another water collector. The water collector greatly increases the contact area between the surface and the air by using a honeycomb structure, thereby increasing the water production effect;

[0014] D: After the deep-sea low-temperature water flows through the high-efficiency water collector, it is discharged back to the ocean to ensure that the water temperature in the refrigeration pipe of the high-efficiency water collector is consistent with the temperature of the deep-sea low-temperature water;

[0015] E: By circulating low-temperature seawater inside the high-efficiency water collector, a cold surface is formed on the surface of the refrigeration tube and directly transferred to the water collecting pipe, so that the water collecting pipe is cooled down. The temperature difference between the surface temperature of the water collecting pipe and the atmospheric environment temperature forms a temperature difference. When the dew point is reached, water droplets are formed on the surface of the water collecting pipe and flow into the water collecting tank;

[0016] F: The water source can enter the purifier through the pipeline. At this time, the water source can be disinfected and purified by the ozone generator and ultraviolet disinfector to produce clean water, which can be stored in the water tank. During the storage process, the water in the water tank is continuously pumped back to the purifier by the circulating water pump for disinfection and purification again, and then transported to the water tank through the pipeline to ensure that the water source in the water tank is clean and safe.

[0017] The high-efficiency water production system includes a pressure-resistant and heat-insulated water intake pipe, a high-pressure self-priming pump, a high-efficiency water collector and a purifier, and a water storage tank, wherein the high-efficiency water collector and the purifier and the water storage tank are connected by a pipeline. A pressure-resistant and heat-insulated water intake pipe is installed at one end of the high-pressure self-priming pump, and one end of the pressure-resistant and heat-insulated water intake pipe is inserted in a deep-sea low-temperature water area.

[0018] Preferably, the pressure-resistant and heat-insulated water intake pipe adopts a high-strength pressure-resistant seamless steel pipe, and the outer surface of the pipe is coated with multiple layers of heat-insulating materials to ensure that it can withstand the high pressure on the seabed and maintain the temperature of the transported deep-sea low-temperature water unchanged.

[0019] Preferably, the high-pressure self-priming pump has extremely strong self-priming ability. According to needs, one or more booster pumps are added to the middle section of the pressure-resistant insulation pipe to ensure that the low-temperature water source is pumped out of the sea surface.

[0020] Preferably, the honeycomb structure of the water collecting pipe adopts an equilateral hexagonal structure according to the honeycomb bionic principle to form a microporous tubular structure to increase the surface area of ​​the refrigeration pipe.

[0021] Preferably, the specific pattern is a bionic pattern on the outer shell of a Namib desert beetle. According to the hydrophilic principle of the Namib desert beetle, the surface of the water collection component is pattern-optimized by laser nanolithography, chemical etching or 3D printing to form a hydrophilic function.

[0022] Preferably, the honeycomb structure is composed of a plurality of pipes, which are honeycomb-shaped and arranged in an equilateral hexagon to form a plurality of honeycomb-shaped pipes, and metal refrigeration pipes are embedded between the plurality of honeycomb-shaped pipes. Low-temperature seawater flows in the refrigeration pipes and conducts the low temperature to the water collecting pipe.

[0023] Preferably, the adsorbent material coated on the surface of the water collecting pipe is a highly absorbent material. The purpose is to utilize the high water absorption of the adsorbent material to increase the water collection efficiency. Common highly absorbent materials are: lithium chloride, silica gel, zeolite molecular sieve and highly absorbent resin (SAP).

[0024] Preferably, the efficient water collecting pipe can be formed by 3D printing, and the adsorption material coated on the surface can be subjected to surface biomimetic treatment by laser nanolithography, chemical etching and other methods to increase the contact area with the air and increase the hydrophilicity.

[0025] Preferably, the purifier adopts ozone disinfection and oxygenation technology and ultraviolet sterilization technology, uses a high-power ozone generator and a venturi ejector, mixes the water source with ozone gas, and performs primary disinfection and oxygenation. At the same time, a flow-through ultraviolet sterilizer is used to kill bacteria in the water when the water flows through the sterilizer, and performs secondary disinfection to ensure the safety and freshness of the water source.

[0026] Preferably, the water storage tank is composed of a 304 stainless steel box, a water level and water temperature sensor, a circulating water pump and a water quality monitor, and an external water outlet or a high-pressure water pump, etc., which is convenient for water extraction or remote water delivery.

[0028] The present invention provides a method for producing water using low-temperature deep-sea water and an efficient water production system. The present invention uses a honeycomb structure water collecting pipe, a surface coated with an adsorbent material, and a surface bionic optimized pattern treatment to further increase the contact area between the surface of the water collecting pipe and the air. At the same time, the water absorption of the adsorbent material and the hydrophilicity of the surface treatment technology are used to solve the problem of reduced efficiency of the condensation water production method under environmental conditions with low temperature and humidity. The system function of maintaining efficient water production is maintained. The adsorbent material treated with a special optimized pattern is superimposed on the surface of the honeycomb water collecting pipe to increase the water absorption capacity of water molecules in the air and increase the hydrophilicity, further increase the ability to form water droplets, and thus further improve the water production efficiency;

[0029] By replacing traditional refrigerants with deep sea cold water, and using natural deep sea low temperature water to replace refrigerants, the honeycomb water collecting pipe cold surface required for water collection is formed. Thus, a large amount of refrigerant is saved, thereby avoiding the pollution of the environment caused by the refrigerant. At the same time, the water pump is used to replace the compressor, which greatly reduces the energy consumption of water production.

[0031] 1) Deep sea cold water is used to replace traditional refrigerants, and the low-temperature seawater in nature is used to obtain the cold surface of the honeycomb structure water collecting pipe required for condensing water. Thus, a large amount of refrigerant is saved and the pollution to the environment caused by the refrigerant is avoided. At the same time, there is no need to use a compressor, saving costs and electricity consumption.

[0032] 2) By using a honeycomb structure, the contact area between the cold surface and the air is greatly increased, thereby improving water production efficiency.

[0033] 3) Highly absorbent materials with specially optimized patterns are superimposed on the surface of the honeycomb water collecting pipe to increase the water absorption capacity of water molecules in the air, improve hydrophilicity, and increase the ability to form water droplets, thereby further improving water production efficiency.
