Description

Technical Field

[0001] The present invention relates to the technical field of gas containers, and in particular to a container system of an aerostat for efficiently separating and recovering light gases. Background Art

[0002] Lightweight gas containers, especially those used to store hydrogen or helium, play a vital role in modern science and industry applications. These containers can be used not only in aerostats (such as balloons and airships), but are also widely used in energy storage, industrial gas supply, scientific research and other fields. However, leakage has always been a key challenge facing these containers. Leakage may not only lead to gas loss, but also cause serious safety accidents. The causes of leakage are varied, including material defects, manufacturing defects, improper operation and environmental factors.

[0003] The leakage rate can usually be used to reflect the leakage of light gas containers. The leakage rate is usually related to multiple parameters, including material properties, container structure, temperature, pressure, and the size and speed of gas molecules. The calculation of leakage rate is usually based on gas dynamics and material science principles.

[0004] CN110726067A relates to a system for compressed air energy storage using double-layer gas tanks, in which the inner tank body of the double-layer gas tank is used to store high-pressure air, and the interlayer space between the inner tank body and the outer tank body is used to store medium-pressure air, the pressure of the medium-pressure air is one pressure level lower than that of the inner high-pressure air, and multiple double-layer gas tanks are connected by pipelines, and the main pipeline of the inner tank body and the main pipeline of the interlayer storage space are connected to the compressor unit and the expansion unit, and the compression and expansion process are controlled by the regulating valve. The inner tank body is placed on the support rail, which is convenient for installation, and enables the tank body to adapt to the deformation and displacement caused by repeated pressure and temperature changes during operation. Although this patent involves two different pressure levels, it only focuses on the relationship between the wall thickness of the inner tank body and the cost, and simply designs a reduced-wall inner tank body "only for bearing the pressure difference between high-pressure air and medium-pressure air" from the perspective of reducing the pressure level of the inner tank body. The core advantage is only cost saving, and the leakage rate problem is not considered.

[0005] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0006] The prior art has disclosed a technical solution for storing gases of different pressures by setting up multiple layers of mutually nested accommodation spaces. For example, CN112644681A discloses an offshore airship that can reciprocate up and down at ultra-low altitude at sea, including a high-pressure airbag layer, an intermediate airbag layer, an outer protective airbag layer, a self-generating power supply module, a sensor module, a control module, and a communication module. The high-pressure airbag layer is located at the center of the offshore airship, and the intermediate airbag layer and the outer protective airbag layer are sequentially sleeved outside the high-pressure airbag layer. The airbags of the high-pressure airbag layer and the intermediate airbag layer are filled with light gas, and the airbag of the outer protective airbag layer is filled with air; the self-generating power supply module, the sensor module, the control module, and the communication module are installed in the intermediate airbag layer; the control module is controllably connected to the inflation valves on each airbag layer, and the light gas and / or air pressure in each airbag layer is adjusted by regulating the opening and closing of the inflation valves, thereby achieving the microgravity balance of the sphere and realizing the upward-downward cyclic reciprocating motion of the offshore airship. However, the original intention of designing the outer protective airbag layer in this technical solution is to ensure the sealed storage of light gas to maintain its floating ability. This design does not take into account the long-term impact of gas leakage and the corresponding solution strategy. The sealing of light gas containers is a key factor. Ideally, the container should be completely sealed to prevent any leakage of gas. However, in actual applications, gas leakage is difficult to completely avoid due to material aging, structural defects or external impacts. Although this leakage may not be easy to detect in the early stage, the cumulative effect of leakage over time will cause the amount of gas to decrease significantly, thereby affecting its floating performance. Since the outer protective airbag layer in this technical solution is in a sealed state and lacks gas recovery and processing measures, the gas stored inside it (including the light gas leaked into it) will leak into the atmosphere through the surface of the outer protective airbag layer, which will lead to the continuous loss of light gas, which significantly reduces the storage efficiency of light gas.

[0007] In view of the deficiencies of the prior art, the present invention provides a container system of an aerostat for efficiently separating and recovering light gases, so as to solve at least part of the above technical problems.

[0008] The present invention discloses a container system for efficiently separating and recovering light gas of an aerostat, which has an aerostat body capable of being filled with and retaining light gas, the outer wall of the aerostat body being configured to have at least a double-layer flexible structure, and capable of directly or indirectly retaining light gas with the aid of an inner skin of the aerostat body. The outer skin of the aerostat body arranged outside its inner skin can form at least one sandwich unit between the inner skin, and the sandwich unit can be filled with a first medium to form at least two pressure gradients between the aerostat body and the outside atmosphere to reduce the diffusion rate of light gas toward the outside atmosphere. The gas in the sandwich unit can be introduced into a recovery unit during the circulation process, wherein the recovery unit is used to separate light gas from a mixed gas composed of the first medium in the sandwich unit and the light gas leaked into the sandwich unit, and to send the separated light gas back to a gas storage chamber for retaining light gas.

[0009] Preferably, the first medium filled in the interlayer unit is different from the light gas retained in the gas storage chamber, and at the same gas pressure, the phase transition temperature of the first medium is higher than the phase transition temperature of the light gas.

[0010] Different from the prior art, the present invention realizes efficient separation and recovery of light gas through the design of double-layer flexible skin structure and sandwich unit. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to effectively reduce the leakage rate of gas and realize the recycling of gas while maintaining the sealing of light gas container. Specifically, the present invention forms a pressure gradient by setting at least one sandwich unit between the inner skin and the outer skin of the floating body and filling it with a first medium. Such a setting significantly reduces the diffusion rate of light gas to the outside atmosphere, because the change of pressure gradient can slow down the diffusion rate of gas molecules. In addition, the phase change temperature of the first medium is higher than that of light gas, which helps to form a stable pressure environment in the sandwich unit and reduce the leakage of light gas. This structure not only improves the sealing performance of the container, but also enhances the safety of the system. By introducing a recovery unit, the present invention can separate and recover light gas from the mixed gas of the sandwich unit, thereby realizing the recycling of light gas and reducing gas loss. This recovery mechanism not only improves the efficiency of resource utilization, but also reduces gas loss due to leakage by returning the separated light gas to the floating body, further improving the sealing performance of the system.

[0011] According to a preferred embodiment, the inner skin of the floating body defines a gas storage chamber for storing lightweight gas, so that the inner skin is used as the side wall of the gas storage chamber, wherein a plurality of diaphragms arranged in parallel are provided in the gas storage chamber, so that the internal space of the gas storage chamber is divided into a plurality of compartments by the diaphragms.

[0012] According to a preferred embodiment, an airbag filled with a second medium different from the light gas is provided in the cabin, wherein the volume occupied by the airbag in the corresponding cabin is changed by adjusting the filling amount of the second medium in the airbag, thereby achieving adjustment of the volume occupied by the light gas in the cabin, thereby changing the overall density of the airship.

[0013] Different from the prior art, the present invention divides the internal space of the gas storage chamber into several compartments by setting a number of parallel arranged diaphragms in the gas storage chamber, and each compartment can be independently controlled and adjusted, thereby improving the safety and reliability of the system. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to achieve efficient storage and isolation of lightweight gases while ensuring the overall structural stability of the gas storage chamber, and how to quickly locate and limit the scope of influence when a local leak occurs. Specifically, the present invention divides the gas storage chamber into several compartments, so that each compartment can independently regulate and control the gas pressure and volume, so that when a leak occurs, the affected compartment can be quickly isolated to avoid the impact from spreading to the entire gas storage system, thereby reducing the impact of a single compartment leakage on the overall system. In addition, this design helps to reduce the flow of gas in the gas storage chamber, reducing the risk of leakage caused by the flow.

[0014] According to a preferred embodiment, the light gas in the gas storage chamber and the first medium in the interlayer unit are filled at different times and / or locations from each other, wherein the light gas in the gas storage chamber and the first medium in the interlayer unit are filled using different gas filling units and / or pressure regulating units.

[0015] Unlike the prior art, the present invention realizes precise control of the filling process by using different gas filling units and pressure regulating units to fill the light gas in the gas storage chamber and the first medium in the interlayer unit. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to achieve efficient collaborative operation between different compartments while maintaining the optimal operating state of each. Specifically, the present invention allows the system to adjust the filling amount of light gas according to the real-time demand in the gas storage chamber and adjust its filling method according to the characteristics of the first medium and the working conditions of the interlayer unit through an independent control strategy. Such a setting can more accurately control the gas filling process and reduce the risk of leakage caused by excessive filling. In addition, the independently controlled gas filling unit and pressure regulating unit can be optimized according to the specific conditions of different compartments to improve the operating efficiency and safety of the entire system.

[0016] According to a preferred embodiment, the interlayer unit obtains the pressure in the cabin through an injection and pressure device, wherein the pressure in the interlayer unit can be adjusted by the injection and pressure device, a controlled valve on the ventilation pipe connected to the injection and pressure device, and / or a decompression device.

[0017] Different from the prior art, the present invention achieves precise adjustment of the pressure in the interlayer unit through the injection and pressure equipment and the controlled valves and pressure reducing equipment on the associated ventilation pipes. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to improve the safety of the system and reduce the risk of gas leakage while maintaining the stability of the gas pressure. The present invention achieves precise adjustment of the pressure in the interlayer unit through the injection and pressure equipment and the controlled valves and pressure reducing equipment on the associated ventilation pipes. This controllability not only helps to maintain the gas within a safe pressure range, but also can further reduce the possibility of gas leakage by dynamically adjusting the pressure, ensuring the long-term stable operation of the system.

[0018] According to a preferred embodiment, the separation and recovery method of the recovery unit is to cause the first medium with a relatively higher phase change temperature in the mixed gas to undergo a phase change, so that the light gas that remains in a gaseous state is separated from the first medium that is converted into a non-gaseous state, thereby returning the separated gaseous light gas to the gas storage chamber.

[0019] Unlike the prior art, the present invention achieves gas-liquid separation by utilizing the phase change of the first medium, thereby further improving the recovery efficiency of light gases. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to effectively separate and recover light gases leaked into the interlayer unit. The present invention achieves gas-liquid separation by utilizing the phase change of the first medium by controlling the environmental conditions in the recovery unit, thereby further improving the recovery efficiency of light gases. Since the phase change temperature of the first medium is higher than that of the light gas, this design can effectively separate the gaseous light gas in a high-altitude and low-temperature environment, reducing the loss of light gas and improving the economy and environmental friendliness of the system.

[0020] According to a preferred embodiment, the recovery unit includes a parameter adjuster, a separator and a heat exchanger, wherein the mixed gas extracted from the interlayer unit passes through the heat exchanger and then enters the parameter adjuster for parameter adjustment, and then the separator is used to separate substances in different phases, the light gas maintained in a gaseous state flows out of the separator from the first channel, and the first medium in a changed phase flows out of the separator from the second channel, and the first channel and / or the second channel can pass through the heat exchanger so that the separated light gas and / or the first medium can perform heat exchange with the mixed gas to be separated in the heat exchanger.

[0021] Unlike the prior art, the recovery unit of the present invention can separate substances in different phases by adjusting parameters. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to achieve accurate separation of different components and optimize energy utilization efficiency in the process of separating light gases. The present invention realizes effective separation and heat exchange of mixed gases through the coordinated work of the parameter adjuster, separator and heat exchanger in the recovery unit. This design not only improves the separation efficiency, but also reduces energy loss through heat exchange, optimizes the energy utilization of the system, and further improves the operating efficiency and safety of the system.

[0022] According to a preferred embodiment, the first medium in the interlayer unit comes from the following components or consists of one of them: carbon dioxide, ethane, methane, ammonia, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, nitrous oxide, sulfur dioxide and / or chlorine; the light gas in the gas storage chamber is helium or hydrogen.

[0023] The present invention selects a suitable first medium, such as carbon dioxide, ethane, etc., whose phase change temperature is higher than that of light gas, which helps to form a stable high-pressure environment in the interlayer unit and reduce the leakage of light gas. At the same time, the selection of these media also takes into account factors such as cost, chemical properties, and environmental friendliness, making the system more economical, safe, and environmentally friendly.

[0024] According to a preferred embodiment, the container system is provided with a control unit for performing pressure control on a recovery unit, a gas filling unit and / or a pressure regulating unit, wherein the control logic of the control unit includes: pressure control of a single compartment, joint pressure adjustment of multiple compartments and / or pressure control between an inner skin and an outer skin.

[0025] Different from the prior art, the present invention realizes independent control of the pressure of a single cabin and joint adjustment of the pressure of multiple cabins by setting a control unit to precisely control the recovery unit, the gas filling unit and the pressure regulating unit. Based on the above-mentioned distinguishing technical features, the problems to be solved by the present invention may include: how to achieve precise control and adjustment of the internal pressure of the system while ensuring the safe and stable operation of the lightweight gas container system. The present invention realizes independent control of the pressure of a single cabin and joint adjustment of the pressure of multiple cabins by setting a control unit to precisely control the recovery unit, the gas filling unit and the pressure regulating unit. This intelligent control logic can monitor and adjust the light gas pressure in the cabin in real time, ensuring that the system can maintain the best operating state under various environmental conditions and reducing the risk of leakage.

[0026] According to a preferred embodiment, the floating body can be connected to the mooring portion through a mooring cable to keep the floating body in a specific area.

[0027] In order to stay in the air for a long time, currently lighter-than-air floating objects such as scientific research balloons or high-altitude exploration balloons use a variety of technologies and strategies to extend their stay in the air, such as the following existing technologies:

[0028] 1. Highly airtight materials: Use highly airtight materials such as multi-layer polyester film or nylon, which have extremely low gas permeability and can effectively reduce the diffusion loss of helium through the material wall.

[0029] 2. Sealing technology: Sealing technology, such as heat welding or special adhesives, is used at the seams and joints of the balloon to ensure a tight seal of gas. These sealing technologies must be able to withstand the extreme temperature and pressure changes at high altitudes.

[0030] 3. Pressure control system: Equipped with a pressure control system, including automatic valves and air bags to regulate the gas pressure inside the balloon. This helps maintain the shape and buoyancy of the balloon while reducing gas leakage caused by pressure changes.

[0031] 4. Gas recovery system: Some airships can be equipped with a gas recovery system that can recover unused helium when the airship lands for reuse. This not only extends the airship's hovering time, but also improves the efficiency of helium use.

[0032] 5. Regular inspection and maintenance: Regularly inspect and maintain the floating body to promptly detect and repair any possible leaks. This includes inspections of valves, joints and other key components.

[0033] 6. Environmental adaptability design: The design of the balloon takes into account the extreme conditions of the high-altitude environment, such as low temperature and strong ultraviolet radiation. The use of weather-resistant materials and coatings can protect the balloon from environmental damage, thereby extending its service life.

[0034] 7. Precise inflation technology: During the inflation process, the amount of helium filled is precisely controlled to avoid over-inflation that causes excessive material stress, thereby reducing potential leak points.

[0035] At present, through the comprehensive application of these technologies and strategies, the floating bodies that stay in the air for a long time can achieve a stay time of from several days to several weeks. In contrast, the design of the aerostat of the present invention allows it to stay in the air for a long time at high altitudes, and the stay time can reach several months to several years, or even ten years to several decades, thereby realizing the efficient and sustainable operation of the wind power generation system.

DETAILED DESCRIPTION

[0046] The following is a detailed description with reference to the accompanying drawings.

[0047] The present invention discloses a container system for efficiently separating and recovering light gases 111, in particular, a container system for an aerostat at high altitude, wherein the high altitude may refer to the stratosphere region, in particular, the bottom of the stratosphere at an altitude of 9000 to 12000 m. Figure 1 It is a structural diagram of the container system.

[0048] Preferably, the container system may be provided with a floating body 100 for storing light gas 111, the floating body 100 may be filled with and maintain light gas 111 for a long time, so as to provide buoyancy, thereby achieving the floating of the floating body 100, wherein the outer wall 200 of the floating body 100 is configured to have at least a double-layer flexible structure, and can directly or indirectly maintain the light gas 111 with the help of the inner skin 220 of the floating body 100. Further, the inner skin 220 of the floating body 100 may define a gas storage chamber 110 for accommodating light gas 111, and the inner skin 220 may serve as a side wall of the gas storage chamber 110 to limit the flow of the light gas 111.

[0049] Preferably, the floating body 100 is provided with an outer skin 210 outside its inner skin 220, and a sandwich cavity can be formed between the outer skin 210 and the inner skin 220, wherein the sandwich cavity between the outer skin 210 and the inner skin 220 can have a very small thickness, especially much smaller than the thickness of the floating body. Preferably, the sandwich cavity can be divided into at least one sandwich unit 300 according to the number of intermediate skins provided between the inner skin 220 and the outer skin 210, and the number of intermediate skins can be 0 or a natural number. Preferably, the sandwich unit 300 can be filled with a first medium 310 to form at least two pressure gradients between the floating body 100 and the outside atmosphere to reduce the diffusion rate of the light gas 111 toward the outside atmosphere. For example, when the number of intermediate skins is 0, the outer wall 200 of the floating body 100 may have a double-layer structure, and the sandwich cavity may include a sandwich unit 300 filled with a first medium 310 to form two pressure gradients between the air storage chamber 110 and the outside atmosphere; Figure 2 As shown, when the number of intermediate skins is 1, the outer wall 200 of the floating body 100 may have a three-layer structure, and the interlayer cavity may include two interlayer units 300 filled with the first medium 310 with different pressures to form three pressure gradients between the air storage chamber 110 and the outside atmosphere; when the number of intermediate skins is 3, the outer wall 200 of the floating body 100 may have a five-layer structure, and the interlayer cavity may include four interlayer units 300 filled with the first medium 310 with different pressures to form five pressure gradients between the air storage chamber 110 and the outside atmosphere.

[0050] Preferably, when only one sandwich unit 300 is formed between the outer skin 210 and the inner skin 220, the structure of the sandwich unit 300 can be defined by the outer skin 210 and the inner skin 220; when multiple sandwich units 300 are formed between the outer skin 210 and the inner skin 220, the sandwich unit 300 relatively closer to the outer skin 210 can be arranged in a manner of being sleeved on the sandwich unit relatively closer to the inner skin 220 to occupy the sandwich cavity between the outer skin 210 and the inner skin 220. Therefore, the structure of the sandwich unit 300 can be adaptively adjusted based on the form of the outer skin 210, the inner skin 220 and the intermediate skin arranged therein.

[0051] Preferably, the first medium 310 filled in the interlayer unit 300 is different from the light gas 111 retained in the gas storage chamber 110 .

[0052] Preferably, the light gas 111 in the gas storage chamber 110 and the first medium 310 in the interlayer unit 300 are filled at different times and / or locations, wherein preferably, the light gas 111 in the gas storage chamber 110 and the first medium 310 in the interlayer unit 300 are filled using different gas filling units and / or pressure regulating units.

[0053] Preferably, the sandwich unit 300 obtains the pressure in the cabin 130 through an injection and pressure device. The pressure in the sandwich unit 300 can be adjusted by the injection and pressure device, a controlled valve on the ventilation pipe connected to the injection and pressure device, and / or a pressure reducing device, especially adjusted in a closed-loop control manner. The injection and pressure device, the controlled valve on the ventilation pipe connected to the injection and pressure device, and / or the pressure reducing device constitute the pressure regulating part of the sandwich unit 300. The pressure regulating part is fixed to the floating body 100 as a whole, or the pressure regulating part is integrated into the floating body 100.

[0054] Preferably, the light gas 111 of the present invention can be helium or hydrogen. Preferably, for an aerostat, helium is safer than hydrogen, but the cost is relatively higher. When selecting the light gas 111, it can be selected according to the actual situation. Exemplarily, the light gas 111 stored in an aerostat floating on land can be helium, and the light gas 111 stored in an aerostat floating on the sea can be hydrogen.

[0055] Preferably, the first medium 310 of the present invention may be a combination of one or more gases having a lower solubility with the light gas 111 and a phase transition temperature higher than that of the light gas 111 .

[0056] The reason why the floating body 100 is arranged in the above manner is that the light gas 111 (such as helium or hydrogen) stored in the container system will leak even in a completely sealed state. Especially for the container system that needs to be at high altitude for a long time, the leakage rate is a key factor affecting its performance. The leakage rate is usually related to a variety of parameters, including material properties, container structure, temperature, pressure, and the size and speed of gas molecules. The calculation of the leakage rate is usually based on gas dynamics and material science principles. The following are the basic steps and related parameters for the calculation of the leakage rate:

[0057] 1. Gas diffusion coefficient D:

[0058] The diffusion coefficient of gas in a material is an important parameter to measure the rate at which gas molecules pass through a material. It is related to the size and speed of the gas molecules and the microstructure of the material.

[0059] The diffusion coefficient can be determined experimentally or estimated using theoretical models such as Fick's law.

[0060] 2. Material thickness L:

[0061] Material thickness directly affects the path length that gas molecules travel. Generally, the thicker the material, the lower the gas leakage rate.

[0062] 3. Pressure difference ΔP:

[0063] The pressure difference between the inside and outside of the container is the main driving force for gas leakage. The greater the pressure difference, the higher the leakage rate.

[0064] 4. Container surface area A:

[0065] The larger the surface area of ​​the container, the more potential paths for gas to escape and the higher the leak rate.

[0066] 5. Temperature T:

[0067] Temperature affects the movement speed and diffusion coefficient of gas molecules. The higher the temperature, the faster the gas molecules move and the higher the leakage rate.

[0068] 6. Gas molecule size and speed:

[0069] Different gas molecules have different sizes and speeds, which directly affects their diffusion rate in the material. For example, hydrogen molecules are smaller than helium molecules, so hydrogen may have a higher leakage rate under the same conditions.

[0070] Therefore, the leakage rate Q can be calculated in a simplified manner by the following formula:

[0071]

[0072] Where Q is the leakage rate (unit: gas volume / time), D is the gas diffusion coefficient, A is the container surface area or pore area, ΔP is the pressure difference, and L is the material thickness.

[0073] It can be seen that as the volume of the floating body 100 increases, its surface area will increase accordingly, and the leakage rate will also increase. In order to reduce the leakage rate, the material thickness L can be increased, and a better coating can be used to reduce the gas diffusion coefficient D. However, for light gases 111 such as hydrogen and helium, the above methods not only increase the cost, but also cannot guarantee that the extremely low leakage rate can be maintained for a long time. These methods are particularly ineffective in reducing the leakage rate for container systems in the high altitude.

[0074] Therefore, the container system of the present invention configures the outer wall 200 of the floating body 100 to have a multi-layer structure so that a sandwich unit 300 is formed between the inner skin 220 and the outer skin 210, and a specified first medium 310 is filled in the sandwich unit 300 to form multiple pressure gradients, thereby effectively reducing the diffusion rate of the light gas 111.

[0075] Preferably, in view of the leakage process of the light gas 111 from the gas storage chamber 110 to the sandwich unit 300, the first medium 310 filled into the sandwich unit 300 has a phase transition temperature higher than the phase transition temperature of the light gas 111. The selection of such a gas helps to form a stable pressure environment in the sandwich unit 300, and reduces the leakage of the light gas 111 to the sandwich unit 300 through the inner skin 220.

[0076] Preferably, the calculation formula of the leakage rate Q shows that the leakage rate is proportional to the gas diffusion coefficient D, the container surface area or pore area A, and the pressure difference ΔP. Therefore, in order to reduce the leakage rate, the following measures can be taken:

[0077] Select appropriate materials as the inner skin 220 and the outer skin 210, and these materials should have low gas permeability to reduce the gas diffusion coefficient D;

[0078] Minimize the pore area during design, for example by optimizing the skin material, seams and connection methods to reduce the hypothetical area of ​​openings or channels that allow gas molecules to pass through;

[0079] By filling the interlayer unit 300 with a gas with a high phase change temperature, a first pressure difference is formed on both sides of the inner skin 220, thereby reducing the diffusion rate of the light gas 111 from the high concentration area (i.e., inside the gas storage chamber 110) to the low concentration area (i.e., the interlayer unit 300), wherein the value of the first pressure difference is smaller than (preferably much smaller than) the pressure difference between the gas storage chamber 110 and the outside atmosphere.

[0080] Preferably, when studying the migration of substances through diffusion processes, the diffusion rate per unit area can be used to describe the intensity and efficiency of the diffusion process. It represents the net amount of substances that pass through a unit area per unit time. The larger the diffusion coefficient, the faster the substance diffuses. The pore area here can refer to the hypothetical area of ​​the openings or channels that allow gas molecules to pass through. It represents the total area of ​​all these microscopic paths, even if they are not visible to the naked eye. The effective pore area is crucial to determining the gas permeation rate because it reflects the number of gas molecules that pass through the membrane per unit time.

[0081] Therefore, compared with the floating body 100 with a single-layer skin for the outer wall 200, the floating body 100 with a double-layer skin for the outer wall 200 has a smaller comprehensive leakage rate. Compared with the two pressure gradients brought by the double-layer skin, three or more layers will bring more pressure gradients. Since the pressure difference between two adjacent cabins 130 has a proportional effect on the leakage rate, multiple gradients help to reduce the leakage rate.

[0082] Preferably, with respect to the leakage process of gas from the interlayer unit 300 to the outside atmosphere, an additional pressure gradient existing between the interlayer unit 300 and the outside atmosphere can be utilized to further reduce the leakage rate, wherein the above-mentioned gas is usually a mixture of the first medium 310 filled in the interlayer unit 300 and the light gas 111 leaked from the gas storage chamber 110 into the interlayer unit 300.

[0083] Preferably, the leakage can be mitigated by utilizing the dynamic pressure induced by the flow by driving the gas in the sandwich unit 300 to circulate. Alternatively, the circulatory flow can be achieved by a built-in fan or other power device.

[0084] Preferably, during the circulation of the gas in the interlayer unit 300 , the recovery unit 400 can be used to recover the light gas 111 leaked into the interlayer unit 300 , so as to collect and reuse the leaked gas, thereby reducing gas loss.

[0085] Preferably, the recovery unit 400 provided in the container system can be used to separate the light gas 111 from the mixed gas consisting of the first medium 310 in the interlayer unit 300 and the light gas 111 leaked into the interlayer unit 300, and return the separated light gas 111 to the gas storage chamber 110 for retaining the light gas 111, thereby realizing the separation of the light gas 111 from the first medium 310 and the recycling of the light gas 111. Figure 2It is a schematic diagram of the arrangement of the recovery unit 400 in the floating body 100. It should be emphasized that: in the present invention, the pipelines in the drawings are only used to show the connection relationship between the unit components, and do not mean that the pipelines are arranged in the manner shown in the drawings. The gas or medium can enter and exit the recovery unit 400 in any feasible manner according to the instructions in the drawings.

[0086] Preferably, if Figure 1 and Figure 2 As shown, the recovery unit 400 can be arranged in the floating body 110 to avoid destroying the streamlined design of the outer contour of the floating body 110. Further preferably, the recovery unit 400 can be arranged in the interlayer unit 300 of the floating body 110 to suck the mixed gas in the interlayer unit 300 through the inlet opened at one end thereof, and discharge the separated first medium 310 into the interlayer unit 300 through the outlet opened at the other end thereof. Such arrangement enables a fluid driving force in a certain direction to be formed in the interlayer unit 300, so that the first medium 310 in the interlayer unit 300 or the mixed gas containing the first medium 310 can flow roughly in a directional direction, thereby forming a certain flow field in the interlayer unit 300, ensuring that the mixed gas can be sucked in by the recovery unit 400 in time and complete separation and recovery. Preferably, the light gas 111 separated by the recovery unit 400 can be transported to one or more chambers 130 and / or to a storage tank for storing the light gas 111 through corresponding pipelines. Preferably, the recovery unit 400 may also be provided with a hole for communicating with the outside atmosphere, and the hole may inhale and / or exhaust air to achieve gas exchange with the outside atmosphere, wherein the hole may be sealed and connected to the outer wall 200 (especially the outer skin 210) of the floating body 110 to prevent air leakage of the sandwich unit 300. In a special embodiment, the recovery unit 400 may also be arranged outside the floating body 110 without destroying the streamlined design of the outer contour of the floating body 110.

[0087] Preferably, the mixed gas composed of the light gas 111 leaked into the interlayer unit 300 and the first medium 310 in the interlayer unit 300 is separated and recovered by the recovery unit 400, and the separation and recovery method is to liquefy the first medium 310 with a relatively higher phase change temperature in the mixed gas into a corresponding liquid substance to achieve gas-liquid separation from the gaseous light gas 111, so that the separated gaseous light gas 111 can be returned to the gas storage chamber 110.

[0088] Figure 3is a working principle diagram of the recovery unit 400. Preferably, the recovery unit 400 may include a parameter adjuster 430, a separator 410 and a heat exchanger 420, wherein the parameter adjuster 430 may be, for example, a refrigerator for adjusting temperature and / or a compressor for adjusting pressure. Preferably, when the first medium 310 is a substance that can be liquefied only by pressure regulation, the parameter adjuster 430 may be configured only as a compressor for adjusting pressure. Furthermore, the mixed gas extracted from the interlayer unit 300 passes through the heat exchanger 420 and then enters the refrigerator for cooling and / or enters the compressor for pressurization; and then the separator 410 is used to separate the substances in different phases, and the light gas 111 maintained in the gaseous state can flow out of the separator 410 from the first channel, and the first medium 310 in the transformed phase can flow out of the separator 410 from the second channel. The first channel and / or the second channel can pass through the heat exchanger 420, so that the separated light gas 111 and / or the first medium 310 can exchange heat with the mixed gas to be separated, thereby achieving pre-cooling of the mixed gas while increasing the temperature of the light gas 111 and / or the first medium 310 according to actual needs.

[0089] Preferably, the separated light gas 111 can be returned to the gas storage chamber 110 through the light gas 111 recovery pipeline. Preferably, the first medium 310 can usually be transformed from a gaseous state to a liquid state in the recovery unit 400 to achieve gas-liquid separation with the light gas 111, wherein the first medium 310 can be selected according to its corresponding physical and chemical properties to select the optimal substance to be filled into the interlayer unit 300. The selection of the type of the first medium 310 is particularly important, which affects both the leakage rate of the light gas 111 and the gas-liquid separation effect, wherein the physical and chemical properties of various types of first media 310 can be determined by means of physical and chemical indicators such as phase diagrams. Preferably, the first medium 310 can be selected from substances that are more prone to phase change than the light gas 111. Since the light gas 111 can usually be determined first, the available first medium 310 can be screened according to the phase change temperature of the light gas 111 from a gaseous state to a liquid or solid state at various gas pressures. In the present invention, the phase change temperature refers to the highest temperature at which any gas changes from a gaseous state to another phase state, wherein, if a gas changes from a gaseous state to a liquid state by cooling under a certain pressure, the phase change temperature is the liquefaction temperature of the gas; if a gas changes directly from a gaseous state to a solid state by cooling under a certain pressure, the phase change temperature is the condensation temperature of the gas. Preferably, the phase change temperature of the first medium 310 can be determined under different conditions based on its phase diagram and the triple point in the phase diagram, wherein the phase change temperature of different substances can reflect the ease of phase change under a certain condition. Preferably, under the same gas pressure, the phase change temperature of the first medium 310 from a gaseous state to a liquid state or a solid state is higher than the phase change temperature of the light gas 111 from a gaseous state to a liquid state or a solid state. Preferably, the ease of phase change of different substances under a certain condition can also be determined by an evaluation index related to enthalpy.

[0090] Preferably, when selecting the first medium 310, the planned working pressure of the first medium 310 can be determined according to the design requirements of the leakage rate of the light gas 111, so as to use the planned working pressure and the planned working temperature (the planned working temperature is roughly equivalent to the ambient temperature of the outside atmosphere and is related to the altitude of the container system) to screen out substances whose current phase is gaseous as alternative media; and then determine the phase change temperature of each alternative medium under the pressure condition according to the planned separation pressure, so as to screen out substances whose phase change temperature is higher than the phase change temperature of the light gas 111 and close to the planned working temperature as the first medium 310 or one of the components of the first medium 310 by comparing the corresponding phase change temperature with the phase change temperature of the light gas 111 and the planned working temperature, wherein the planned separation pressure can be the same as the planned working pressure. Further preferably, when screening the optional medium of the first medium 310, one or more factors of its cost, chemical properties, environmental friendliness, and solubility in the light gas 111 can also be considered.

[0091] Preferably, after screening, the first medium 310 may come from the following components or be composed of one of them: carbon dioxide (CO2), ethane (C2H6), methane (CH4), ammonia (NH3), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), nitrous oxide (N2O), sulfur dioxide (SO2) and / or chlorine (Cl2).

[0092] In one embodiment, the first medium 310 may be Freon R134a, which belongs to hydrofluorocarbon (HFC), and its full name is 1,1,1,2-tetrafluoroethane (C2H2F4). At 0.25atm, its boiling point is about -60.8°C; at 0.5atm, its boiling point is about -44.8°C; at standard atmospheric pressure (1atm), its boiling point is about -26.1°C, which means that the cost of separating the mixed gas composed of Freon R134a as the first medium 310 and the light gas 111 at high altitude is extremely low. This is because the environmental parameters of the outside atmosphere at an altitude of 10,000 meters are a temperature of about -50°C and a pressure of about 0.25atm. In order to ensure that Freon R134a remains in a gaseous state at the planned working temperature, its planned working pressure can be set to be slightly higher than 0.25atm. At this time, the compressor only needs to slightly increase the pressure of the mixed gas (for example, from slightly higher than 0.25atm to 0.5atm or 1atm) to utilize the high-altitude low-temperature characteristics to achieve the liquefaction of the first medium 310, thereby separating the light gas 111. This setting not only reduces the recycling cost, but also can utilize the roughly equal pressure on both sides of the outer skin 210 to prevent the mixed gas from leaking to the outside atmosphere, thereby improving the recycling efficiency, and is particularly suitable for the first medium 310 with similar physical and chemical properties to Freon R134a.

[0093] In another embodiment, the first medium 310 may be carbon dioxide (CO2). According to the three-phase diagram of carbon dioxide, its triple point is -56.6°C and 5.11atm. Therefore, carbon dioxide at the planned working pressure and the planned working temperature can be filled in the interlayer unit 300 in the form of gas and form a corresponding pressure gradient. Further, the outside atmospheric temperature (i.e., the planned working temperature) at an altitude of 10,000 meters is about -50°C, which is greater than -56.6°C in the triple point. At this temperature, carbon dioxide may be solid, liquid or gaseous, and is related to the corresponding pressure value, wherein, at this temperature, the pressure value is higher than the solid-liquid line for solid carbon dioxide, the pressure value is lower than the gas-liquid line for gaseous carbon dioxide, and the pressure value is between the solid-liquid line and the gas-liquid line for liquid carbon dioxide. Therefore, by using a compressor to adjust the pressure of the mixed gas between the gas-liquid line and the solid-liquid line corresponding to the planned working temperature, the liquefaction of carbon dioxide can be achieved, thereby completing the separation from the light gas 111. Preferably, the first medium 310 uses carbon dioxide as the advantage that: as a gas naturally existing in the atmosphere, carbon dioxide has good environmental compatibility and can reduce the impact of the system on the environment. In addition, the thermodynamic properties of carbon dioxide enable it to remain in a gaseous state under high pressure and low temperature conditions, which is conducive to maintaining the required pressure gradient in a high-altitude environment. At the same time, carbon dioxide is relatively safe, has little impact on materials, and its adaptability enables it to maintain stable operation of the system under different environmental conditions.

[0094] Preferably, when the first medium 310 is selected as carbon dioxide, its gas source can come from the outside atmosphere, wherein direct air capture (DAC), membrane separation and other technologies can be used to extract carbon dioxide from the air at high altitude, so that the extracted carbon dioxide is supplied to the interlayer unit 300 as a supplementary gas source to make up for the loss of the first medium 310. Preferably, the direct air capture technology uses chemical or physical methods to separate and capture carbon dioxide in the air, wherein the carbon dioxide is adsorbed on the material by sending the air into a specific device, and then released by heating or decompression for collection and storage. Such a setting realizes the recycling of resources. The direct extraction of carbon dioxide at high altitude by direct air capture (DAC) or membrane separation technologies not only reduces the dependence on the supply of the first medium 310, reduces the carrying amount of the first medium 310, but also helps to reduce the greenhouse gas content in the atmosphere and promote environmental sustainability. In addition, the application of this technology also has potential economic advantages, because by recycling and reusing carbon dioxide, the gas supply cost in the operation of the system can be reduced, and the economy of the system can be improved.

[0097] Table 1 above shows the phase transition temperature, critical temperature, cost, chemical properties, environmental friendliness and helium solubility of some gases at 1 standard atmospheric pressure.

[0098] When ammonia is selected, since rubber, plastic or other synthetic materials may be sensitive to ammonia, the present invention selects materials and coatings with good tolerance to ammonia to process or form the insulation layer of the sandwich unit 300. Similarly, for other corrosive gases, corresponding materials and coatings are selected.

[0099] In practical applications, it is also necessary to consider the effect of temperature on the diffusion coefficient, the actual concentration of the gas, and other factors that may affect the diffusion process, such as the porosity and structural heterogeneity of the skin. In addition, for a specific gas and skin material combination, the inventors have experimentally determined the corresponding diffusion coefficient for various working conditions.

[0100] Preferably, a plurality of diaphragms 120 arranged in parallel may be provided in the air storage chamber 110 of the floating body 100, so as to use the diaphragms 120 to divide the internal space of the air storage chamber 110 into a plurality of chambers 130, wherein the volumes of the divided chambers 130 may be the same or different based on the different arrangement positions of the diaphragms 120. Preferably, each chamber 130 of the air storage chamber 110 may be filled with a light gas 111, and an air bag 140 may be provided in each chamber 130, wherein the air bag 140 is filled with a second medium 141 different from the light gas 111. Preferably, the second medium 141 filled in the airbag 140 provided in each chamber 130 of the air storage chamber 110 may be air, so as to change the size of the volume occupied by the airbag 140 in the corresponding chamber 130 by adjusting the amount of air filled in the airbag 140, thereby adjusting the volume occupied by the light gas 111 in the chamber 130, thereby changing the overall density of the container system of the aerostat. Further, when the amount of air filled in the airbag 140 increases, the overall density of the aerostat increases, causing the aerostat to descend; when the amount of air filled in the airbag 140 decreases, the overall density of the aerostat decreases, causing the aerostat to ascend. Figure 4 Another preferred configuration of the container system is shown.

[0101] like Figure 5 As shown, the floating body 100 of the container system can be connected to a mooring cable 500. Further, the other end of the mooring cable 500 can be connected to a mooring part arranged on the ground, so that the mooring part can provide a certain pulling force to the floating body 100 through the mooring cable 500 to keep the floating body 100 in a specific area. The design of the aerostat of the present invention allows it to stay in the air for a long time at high altitudes, and the stay time can reach several months to several years, or even ten years to several decades.

[0102] Preferably, the container system of the present invention may be provided with a control unit for pressure control, wherein the control unit may control the recovery unit 400, the gas unit and / or the pressure regulating unit. Preferably, the control logic of the control unit may include: pressure control of a single chamber 130, joint pressure adjustment of multiple chambers 130 and / or pressure control between the inner skin 220 and the outer skin 210. Preferably, in addition to controlling the recovery unit 400, the gas unit and / or the pressure regulating unit, the control unit may also be used to control the attitude, height and position of the floating body 100.

[0103] Preferably, when the control unit performs pressure control of a single chamber 130, each chamber 130 may be equipped with an independent sensor and a pressure regulating valve for real-time monitoring and adjustment of the pressure of the light gas 111 in the chamber 130. The control unit may automatically adjust the amount of gas inflated in each chamber 130 according to the preset pressure range and the current environmental conditions to ensure that the pressure of the light gas 111 in each chamber 130 is maintained at a predetermined level, wherein the control unit may calculate the required opening and closing degree of the pressure regulating valve according to the preset optimal working pressure range and environmental condition parameters. For example, the control unit may adopt a proportional-integral-differential (PID) controller to dynamically adjust the valve position according to the deviation between the actual pressure and the set target. Preferably, according to the calculation results, the control unit will automatically send instructions to the actuators of each pressure regulating valve to adjust its opening and closing state to change the gas flow rate and achieve fine control of the pressure. When it is detected that the pressure of a certain chamber 130 deviates from the predetermined value, the control unit will start the corresponding inflation or exhaust mechanism, especially the separated and recovered light gas 111 can be used to achieve fast and accurate pressure adjustment.

[0104] Preferably, when the control unit performs joint pressure adjustment of multiple chambers 130, it can regulate the (cross) valves provided on the pipelines connecting the multiple chambers 130 to allow the light gas 111 to flow between the multiple chambers 130 to achieve pressure balance. Preferably, the control unit can use intelligent logic, such as a fuzzy logic controller or a neural network, to analyze the pressure difference between the chambers 130 and calculate the valves that need to be adjusted to achieve pressure balance. For example, if it is detected that the pressure difference between the chambers 130 exceeds a preset range, the control unit can adjust the cross valves connecting these chambers 130 to allow the gas to flow from the relatively high-pressure chamber 130 to the relatively low-pressure chamber 130 until the pressure is balanced.

[0105] Preferably, the control unit may use a pressure sensor to monitor the pressure of the first medium 310 injected into the sandwich unit 300 through a dedicated inflatable component when controlling the pressure between the inner skin 220 and the outer skin 210. If leakage of the light gas 111 is detected, the control system may start the recovery unit 400 to separate the first medium 310 from the light gas 111 by phase change, thereby returning the separated first medium 310 to the sandwich unit 300 to maintain the pressure.

[0106] Preferably, when a pressure anomaly or system failure is detected, the control unit should be able to respond quickly and initiate an emergency plan, such as closing relevant valves, activating a backup gas source, or adjusting the system configuration to ensure the safety and stability of the system.

[0107] According to a preferred embodiment, the present invention further discloses an aerostat capable of realizing wind power generation, the aerostat includes the aforementioned container system, wherein a wind turbine generator set 600 may be installed on the aerostat, the wind turbine generator set 600 being configured to capture high-altitude wind energy and convert it into electrical energy to realize wind power generation. Further, the wind turbine generator set 600 may be arranged on the aerostat body 100. Figure 6 is a schematic diagram of a container system equipped with a wind turbine generator set 600 of the present invention. Further, Figure 7 yes Figure 6 The internal structure of the container system shown is different from Figure 1 The structure of the container system shown is a different preferred embodiment. Figure 6 and Figure 7 In the container system shown, a wind duct for airflow is provided inside the floating body 100, so that the wind turbine generator set 600 disposed in the wind duct can capture the wind energy in the wind duct and convert it into electrical energy.

[0108] Preferably, the container system equipped with the wind turbine generator set 600 may be provided with an energy transmission unit, which will provide bidirectional power supply to the aerostat. With the help of the aerostat that stays in the air for a long time at high altitude, efficient and sustainable operation of the wind power generation process can be achieved.

[0109] Preferably, the combination of the wind turbine generator set 600 and the airship ensures that the unit can stably capture wind energy at high altitudes. At the same time, through the recovery mechanism of the light gas 111, the difficult operation of replenishing the light gas 111 when the airship is in a long-term floating state is avoided, thereby improving the economy and environmental friendliness.
