DETAILED DESCRIPTION

[0026] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] like Figures 1 to 5 As shown, the first embodiment of the present invention provides an adsorption component for obtaining helium-3, comprising: A housing 100 is formed with a receiving space 102 in the housing 100, the receiving space 102 is filled with an adsorbent 104, and a heat exchange portion 106 for exchanging heat with an external refrigerant is formed on a side wall of the housing 100; A heat conducting member 108 is disposed in the accommodating space 102 , and the heat conducting member 108 is used to achieve heat exchange with the adsorbent 104 ; The flanges 110 are connected to two ends of the housing 100 to close the accommodating space 102 .

[0028] According to the adsorption assembly for obtaining helium-3 provided by the embodiment of the first aspect of the present invention, by optimizing the type selection and filling method of the adsorbent 104, and accurately controlling the temperature of the adsorbent 104, the adsorption assembly of the present invention can achieve efficient helium-3 adsorption. This not only improves the extraction efficiency of helium-3, but also reduces energy consumption and cost. With the design of the external refrigerant, the heat exchange part 106 and the heating component, the user can easily adjust the temperature inside the adsorption assembly to adapt to different operating conditions and requirements. This temperature controllability enables the adsorption assembly to maintain the best working state in a variety of application scenarios. The design of the flange 110 connection makes the disassembly and cleaning of the adsorption assembly simple and easy. This not only reduces maintenance costs and time, but also improves the reliability and service life of the adsorption assembly. The structural design of the entire adsorption assembly is compact and reasonable, occupies a small area, and is easy to install and use. This enables the adsorption assembly of the present invention to perform excellent performance in a variety of environments such as laboratories and industrial sites. The adsorption component for obtaining helium-3 provided by the present invention has the advantages of high efficiency, controllability, easy maintenance and compact structure, etc., and provides a new solution for the extraction and separation of helium-3. The purity of helium-3 can be increased from 99% to 99.999%, which is conducive to meeting the demand for high-purity helium-3 in cutting-edge scientific research.

[0029] Please continue to see Figures 1 to 5The shell 100 is the main structure of the entire adsorption assembly, and its interior is designed with a spacious accommodation space 102 for filling the adsorbent 104 with high adsorption performance. The material selection of the shell 100 is very important, and it must have sufficient strength and sealing performance to ensure that there will be no leakage due to pressure or temperature fluctuations during the adsorption process. In addition, a heat exchange part 106 is set on the side wall of the shell 100. This design allows the external refrigerant to easily exchange heat with the adsorbent 104 inside the shell 100, thereby achieving precise control of the temperature of the adsorbent 104.

[0030] The adsorbent 104 filled in the accommodation space 102 is the core of the adsorption assembly. The adsorbent 104 is responsible for efficiently capturing helium-3 from the mixed gas. In order to ensure high adsorption efficiency and selectivity, the selection of the adsorbent 104 needs to be strictly screened and optimized. At the same time, the filling density and distribution of the adsorbent 104 also need to be precisely controlled to achieve the best adsorption effect.

[0031] In the embodiment of the present invention, the adsorbent 104 may be coconut shell activated carbon with larger particles or even nano-scale metal organic framework materials.

[0032] The heat transfer element 108 is disposed in the accommodation space 102, in close contact with the adsorbent 104 or maintaining an efficient heat exchange channel. Its main function is to efficiently transfer the heat of the external refrigerant to the adsorbent 104, thereby achieving precise regulation of the temperature of the adsorbent 104. By precisely controlling the temperature of the adsorbent 104, the adsorption and desorption process of helium-3 can be further optimized and the overall efficiency can be improved.

[0033] In the embodiment of the present invention, the heat conducting member 108 may be made of a copper mesh, and the specification of the copper mesh may be flexibly adjusted based on the particle size of the adsorbent 104 . For example, the copper mesh may be a high-purity copper mesh of 50-100 mesh.

[0034] As a component connecting the two ends of the housing 100, the flange 110 not only seals the accommodating space 102, but also ensures the sealing and stability of the entire adsorption assembly. The flange 110 is designed to be easy to disassemble and clean, so that the adsorption assembly can be maintained and the adsorbent 104 can be replaced when necessary.

[0035] According to one embodiment of the present invention, a gas pipeline for introducing a helium isotope mixture is provided in the accommodating space 102 , a positioning piece 112 is provided at the end of the outer shell 100 , and the gas pipeline and the flange 110 are suitable for being coaxially installed with the outer shell 100 through the positioning piece 112 .

[0036] In one embodiment of the present invention, the housing 100 of the adsorption assembly for obtaining helium-3 is further optimized, especially by adding a positioning member 112 at its end. This innovative design is intended to ensure that the gas pipeline and the flange 110 can be more accurately and stably coaxially installed with the housing 100.

[0037] Specifically, the positioning member 112 is disposed at the end of the housing 100, and its shape and size are carefully designed to perfectly match the interface of the gas pipeline and the flange 110. During installation, the gas pipeline and the flange 110 can be precisely docked with the housing 100 through the positioning member 112, thereby ensuring the coaxiality therebetween. This design not only improves the convenience and accuracy of installation, but also helps to reduce performance loss or safety hazards caused by improper installation.

[0038] In addition, the positioning member 112 also has a certain strength and rigidity, and can provide stable support for the gas pipeline and the flange 110 during installation and use. This helps to prevent problems such as reduced heat transfer efficiency or damaged sealing performance caused by shaking of the pipeline or flange 110.

[0039] The design of the positioning member 112 enables the gas pipeline and the flange 110 to be coaxially installed with the housing 100, thereby greatly improving the accuracy and stability of the installation. This helps to ensure the uniformity and efficiency of heat transfer, thereby improving the performance of the entire adsorption assembly. The positioning member 112 provides stable support for the gas pipeline and the flange 110, helping to prevent performance loss or safety hazards caused by shaking. This enhances the structural stability of the entire adsorption assembly and extends its service life. The design of the positioning member 112 simplifies the installation process, allowing operators to complete the installation work more conveniently and quickly. This not only reduces installation costs, but also improves work efficiency. By optimizing the installation process and improving performance stability, the positioning member 112 design in the present invention helps to enhance the overall user experience. During use, users can rely more confidently on the performance of the adsorption assembly, thereby focusing more on the extraction and separation of helium-3.

[0040] According to one embodiment of the present invention, a positioning boss 114 is formed on the positioning member 112 along the circumference of the positioning member 112 for positioning and adapting to the housing 100 , and a positioning structure 116 is formed on the side of the positioning member 112 facing the accommodating space 102 for positioning and adapting to the gas pipeline.

[0041] In one embodiment of the present invention, the design of the positioning member 112 is significantly enhanced to better meet the coaxial installation requirements between the housing 100, the gas pipeline and the flange 110. Specifically, along the circumference of the positioning member 112, a positioning boss 114 is formed thereon for positioning and matching with the housing 100, and at the same time, a positioning structure 116 for positioning and matching with the gas pipeline is designed on one side of the positioning member 112 facing the accommodating space 102.

[0042] The positioning boss 114 is designed to ensure accurate docking between the positioning member 112 and the housing 100. Its shape and size are carefully designed to perfectly match the corresponding structure on the housing 100. During installation, the positioning boss 114 can be easily inserted into the corresponding position of the housing 100, thereby achieving a stable connection between the positioning member 112 and the housing 100. This design not only improves the convenience of installation, but also helps to ensure the coaxiality between the positioning member 112 and the housing 100, thereby ensuring the performance stability of the entire adsorption assembly.

[0043] The positioning structure 116 is designed to achieve more accurate positioning and docking with the gas pipeline. The positioning structure 116 can be a groove, a bump or other shaped structure, and its shape and size match the interface of the gas pipeline. During the installation process, the gas pipeline can easily dock with the positioning structure 116, thereby achieving a stable connection with the gas pipeline. This design not only improves the accuracy of installation, but also helps to reduce problems such as reduced heat transfer efficiency or impaired sealing performance caused by improper installation.

[0044] The design of the positioning boss 114 and the positioning structure 116 enables the positioning member 112 to be precisely docked with the housing 100 and the gas pipeline, respectively, thereby greatly improving the accuracy and stability of the installation. This helps to ensure the uniformity and efficiency of heat transfer, thereby improving the performance of the entire adsorption assembly. Through the stable connection of the positioning boss 114 and the positioning structure 116, the connection between the positioning member 112, the housing 100 and the gas pipeline is more secure and reliable. This helps to prevent performance loss or safety hazards caused by loose connections, thereby extending the service life of the entire adsorption assembly. The design of the positioning boss 114 and the positioning structure 116 simplifies the installation process, allowing operators to complete the installation work more conveniently and quickly. This not only reduces installation costs, but also improves work efficiency. By optimizing the installation process and improving performance stability, the design of the positioning member 112 in the present invention helps to enhance the overall user experience. Users can rely on the performance of the adsorption assembly more confidently during use, thereby focusing more on the extraction and separation of helium-3.

[0045] According to one embodiment of the present invention, a welding transition piece 118 is disposed between the flange 110 and the end of the housing 100 .

[0046] In one embodiment of the present invention, in order to further enhance the connection strength and sealing performance between the flange 110 and the housing 100 , a welding transition piece 118 is provided between the flange 110 and the end of the housing 100 .

[0047] Specifically, the welding transition piece 118 is a specially designed connection 120 piece, and its shape and size are carefully designed to perfectly match the ends of the flange 110 and the shell 100. The welding transition piece 118 is usually made of the same or similar material as the flange 110 and the shell 100 to ensure compatibility and welding quality therebetween.

[0048] During installation, the welding transition piece 118 is first placed between the flange 110 and the end of the housing 100, and then firmly connected to the two by welding technology. This welding connection not only provides strong mechanical strength, but also helps to ensure the sealing performance of the connection to prevent any gas or liquid leakage.

[0049] The design of the welded transition piece 118 makes the connection between the flange 110 and the housing 100 more secure and reliable. This welded connection provides strong mechanical strength and can withstand higher pressure and temperature fluctuations, thereby extending the service life of the entire adsorption assembly. Through the connection of the welded transition piece 118, the sealing performance between the flange 110 and the housing 100 is significantly improved. This sealing performance is crucial to prevent the leakage of gas or liquid, especially when dealing with rare and expensive gases such as helium-3. Although the addition of the welded transition piece 118 may increase some manufacturing costs, it also simplifies the manufacturing process. By pre-manufacturing and testing the welded transition piece 118, high-quality welded connections can be ensured during the final assembly process, thereby reducing uncertainties and risks in the manufacturing process. The design of the welded transition piece 118 not only enhances the connection strength and sealing performance, but also helps to improve the overall performance of the entire adsorption assembly. This includes improving heat transfer efficiency, reducing energy consumption, and improving the extraction efficiency of helium-3.

[0050] According to one embodiment of the present invention, a connection portion 120 for connecting with the flange 110 is disposed at one end of the welding transition piece 118 facing the flange 110 , and an installation portion 122 for installing and connecting with the positioning piece 112 is disposed inside the welding transition piece 118 .

[0051] In one embodiment of the present invention, the design of the welding transition piece 118 is further improved. Specifically, a connection portion 120 for connecting with the flange 110 is provided at one end of the welding transition piece 118 facing the flange 110, and a mounting portion 122 for mounting the positioning piece 112 is designed inside the welding transition piece 118.

[0052] The connection part 120 is designed to ensure a stable connection between the welded transition piece 118 and the flange 110. It can be a flange 110 disc, a threaded interface or other forms of connection structure, depending on the type and size of the flange 110. The shape and size of the connection part 120 are carefully designed to perfectly match the corresponding structure on the flange 110, thereby achieving a tight connection and reliable sealing.

[0053] The mounting portion 122 is designed to achieve a more accurate and stable connection with the positioning member 112. It can be a groove, a hole, or other forms of mounting structures, depending on the shape and size of the positioning member 112. During the installation process, the positioning member 112 can be easily docked with the mounting portion 122 and firmly connected to the welding transition member 118 through appropriate fixing methods (such as bolts, welding, etc.). This design not only improves the accuracy of installation, but also helps to ensure the stability and reliability of the positioning member 112 on the welding transition member 118.

[0054] The design of the connecting portion 120 makes the connection between the welding transition piece 118 and the flange 110 more firm and reliable, thereby improving the connection strength and sealing performance of the entire adsorption assembly. This helps to prevent gas or liquid leakage, especially in high pressure or high temperature environments. The design of the mounting portion 122 enables the positioning piece 112 to be accurately connected to the welding transition piece 118, thereby improving positioning accuracy and stability. This helps to ensure the coaxiality between the gas pipeline and the housing 100, thereby ensuring the uniformity and efficiency of heat transfer. The design of the connecting portion 120 and the mounting portion 122 simplifies the installation process, allowing operators to complete the installation of the welding transition piece 118, flange 110 and positioning piece 112 more conveniently and quickly. This not only reduces installation costs, but also improves work efficiency. By optimizing the design of the connecting portion 120 and the mounting portion 122, the welding transition piece 118 embodiment of the present invention helps to improve the overall performance of the entire adsorption assembly. This includes improving heat transfer efficiency, reducing energy consumption, enhancing structural reliability, and improving the extraction efficiency of helium-3.

[0055] According to an embodiment of the present invention, an air hole 124 is provided on the housing 100 and is in fluid communication with the accommodating space 102 . A filter is disposed at a position on the housing 100 corresponding to the air hole 124 .

[0056] In one embodiment of the present invention, the design of the housing 100 is further improved, in particular, a filter is added to the air hole 124 that is in fluid communication with the accommodating space 102 .

[0057] Specifically, the housing 100 is provided with air holes 124 directly connected to the accommodating space 102, and these air holes 124 allow fluid (such as gas) to be exchanged between the accommodating space 102 and the external environment. In order to ensure the quality of the fluid entering the accommodating space 102, a filter is provided at a position corresponding to the air holes 124 on the housing 100.

[0058] The filter element is designed to capture and block impurities, particles and other unwanted substances in the fluid, so that only pure fluid is allowed to enter the accommodation space 102. It can be a filter, a filter or other forms of filtering structure, depending on the type of fluid to be filtered and the size of impurities. The material of the filter element is also carefully selected to ensure that it has good filtering performance, corrosion resistance and durability.

[0059] In the embodiment of the present invention, the filtering accuracy of the filter element can be determined according to the selection of the adsorbent.

[0060] The filter element can effectively capture and block impurities and particles in the fluid, thereby ensuring the quality of the fluid entering the accommodating space 102. This helps prevent impurities from contaminating the interior of the adsorption component, thereby affecting its performance and life. By filtering impurities in the fluid, the filter element helps protect the adsorption material in the accommodating space 102 from damage. This can extend the service life of the adsorption material and improve its adsorption efficiency and selectivity. Pure fluid helps maintain the stability of the internal environment of the adsorption component, thereby enhancing the stability and reliability of the entire system. This helps to ensure the performance and efficiency of the adsorption component during long-term operation. By ensuring the quality of the fluid entering the accommodating space 102, the filter element design in the present invention helps to enhance the overall user experience. Users can rely on the performance of the adsorption component with greater confidence during use and reduce maintenance and replacement costs caused by fluid contamination.

[0061] According to an embodiment of the present invention, a first mounting hole 126 is provided on the heat exchange portion 106 , and the first mounting hole 126 is used to install a temperature detection component.

[0062] In one embodiment of the present invention, the design of the heat exchange portion 106 is optimized, and in particular, a first mounting hole 126 is provided thereon for mounting a temperature detection element.

[0063] The heat exchange part 106 is a key component responsible for heat exchange in the adsorption assembly, and is usually connected to a refrigerant to achieve heat transfer and regulation. In order to ensure that the temperature of the heat exchange part 106 can be accurately and real-time monitored, a first mounting hole 126 is opened on the heat exchange part 106 .

[0064] The shape and size of the first mounting hole 126 are carefully designed to perfectly match the interface of the temperature detection element (such as a thermocouple, a thermal resistor, etc.). During the installation process, the temperature detection element can be easily inserted into the first mounting hole 126 and firmly connected to the heat exchange part 106 through an appropriate fixing method (such as a threaded connection, a buckle, etc.). This design not only improves the convenience of installation, but also helps to ensure the stability and reliability of the temperature detection element on the heat exchange part 106.

[0065] The temperature detection component installed through the first mounting hole 126 can monitor the temperature of the heat exchange part 106 in real time and accurately. This helps to promptly detect and solve potential overheating or temperature abnormalities, thereby ensuring the safe operation of the adsorption component. Accurate temperature monitoring data helps to achieve more precise system control. According to the real-time data provided by the temperature detection component, the flow rate, temperature and other parameters of the refrigerant can be adjusted to optimize the performance and efficiency of the adsorption component. Real-time temperature monitoring helps prevent system failures caused by abnormal temperatures. By promptly detecting and handling temperature problems, the service life of the adsorption component can be extended and its overall reliability can be improved. The design of the first mounting hole 126 makes the installation and replacement of the temperature detection component more convenient. When the temperature detection component needs to be maintained or replaced, the operator can easily operate through the first mounting hole 126, thereby reducing maintenance costs and time.

[0066] According to an embodiment of the present invention, a second mounting hole 128 is provided on the heat exchange portion 106 , and the second mounting hole 128 is used to mount a heater.

[0067] In one embodiment of the present invention, the design of the heat exchange portion 106 is further optimized, in particular, a second mounting hole 128 is added thereon, which is specifically used for mounting a heater.

[0068] As a core component of the adsorption assembly, the heat exchange part 106 is not only responsible for heat exchange, but may also need to heat the fluid in some cases to meet specific process requirements. In order to meet this requirement, a second mounting hole 128 is opened on the heat exchange part 106.

[0069] The shape and size of the second mounting hole 128 are carefully designed to ensure that the heater (such as an electric heating rod, a heating plate, etc.) can be easily attached to the surface or inserted and fixed therein. During the installation process, the heater is tightly connected to the heat exchange part 106 through the second mounting hole 128, thereby ensuring effective heat transfer.

[0070] The heater installed through the second mounting hole 128 can accurately control the heating of the heat exchange part 106. This helps to meet specific process requirements, such as achieving the desorption of helium-3. After adding the heater, the system flexibility of the entire adsorption assembly is significantly improved. The operator can flexibly adjust the power and working time of the heater according to actual needs to optimize the performance and efficiency of the system. In some cases, such as when the ambient temperature is low or the initial temperature of the fluid is low, the heater can provide the necessary heat supplement to ensure the normal operation of the adsorption assembly. This enhances the adaptability of the system to different environmental conditions. The design of the second mounting hole 128 makes the installation and replacement of the heater more convenient. When the heater needs to be maintained or replaced, the operator can easily operate through the second mounting hole 128, thereby reducing maintenance costs and time.

[0071] According to an embodiment of the present invention, a third mounting hole 130 is provided on the heat exchange portion 106 , and the third mounting hole 130 is used to install the heat exchange portion 106 at a target position.

[0072] In one embodiment of the present invention, the design of the heat exchange unit 106 is further optimized, in particular, a third mounting hole 130 is added thereon, which is specifically used to firmly mount the heat exchange unit 106 at a target location (such as inside the housing 100, a device bracket, etc.).

[0073] As a key component in the adsorption assembly, the heat exchange part 106 has a critical role in the performance and efficiency of the entire system. In order to ensure that the heat exchange part 106 can be accurately installed at the target position and maintain its stability and reliability, a third mounting hole 130 is provided on the heat exchange part 106 .

[0074] The shape, size and position of the third mounting hole 130 are carefully designed to ensure a perfect match with the interface of the mounting parts (such as bolts, nuts, buckles, etc.). During the installation process, the operator can use appropriate mounting parts to firmly fix the heat exchange part 106 to the target position through the third mounting hole 130. This design not only improves the convenience of installation, but also helps to ensure the stability and reliability of the heat exchange part 106 during long-term use.

[0075] Through the third mounting hole 130, the operator can more accurately install the heat exchange part 106 at the target position. This helps to ensure the relative position relationship between the heat exchange part 106 and other components, thereby optimizing the performance and efficiency of the entire system. The design of the third mounting hole 130 enables the heat exchange part 106 to be firmly fixed at the target position, avoiding loosening or displacement caused by factors such as vibration and impact during use. This enhances the stability of the heat exchange part 106 and extends its service life. The third mounting hole 130 makes the installation process of the heat exchange part 106 simpler and more convenient. The operator does not need to perform complex positioning and fixing operations, but only needs to use appropriate mounting parts to fix the heat exchange part 106 at the target position through the third mounting hole 130. This reduces installation costs and time. A stable heat exchange part 106 helps to improve the reliability of the entire adsorption assembly. By ensuring the stability and accuracy of the heat exchange part 106 during long-term use, system failures and performance degradation caused by factors such as looseness and displacement can be reduced.

[0076] See also Figure 6 The second aspect of the present invention provides a method for using the above-mentioned adsorption component for obtaining helium-3, comprising: Step 10, installing a flange 110 at one end of the housing 100; Step 20, filling the accommodating space 102 with the heat conducting member 108 and the adsorbent 104; Step 30, installing a flange 110 at the other end of the housing 100; Step 40, exchanging heat with the heat exchange part 106 through the external refrigerant.

[0077] According to the method for using the adsorption assembly for obtaining helium-3 based on the above-mentioned embodiment provided by the second aspect of the present invention, by accurately controlling the temperature environment inside the adsorption assembly, the adsorption efficiency of the adsorbent 104 can be optimized, thereby improving the extraction efficiency of helium-3. The sealing and connection strength of the flange 110 ensure the stability and reliability of the adsorption assembly during long-term use, and reduce system failures caused by leakage and other problems. The method has clear steps and simple operation, which reduces the skill requirements and workload of the operator. Through reasonable filling of the heat conduction member 108 and the adsorbent 104 and precise heat exchange control, the overall performance of the adsorption assembly can be significantly improved, including heat transfer efficiency, adsorption efficiency and system reliability. The method for using the adsorption assembly based on the above-mentioned embodiment provided by the second aspect of the present invention provides an efficient, stable and simple solution for the extraction of helium-3.

[0078] like Figure 6As shown, the second embodiment of the present invention provides a method for using the cryogenic adsorption assembly for obtaining high-purity helium-3. The method describes in detail how to effectively use the adsorption assembly to extract helium-3.

[0079] Step 10: Install flange 110 on one end of housing 100 In this step, the operator needs to install the flange 110 to one end of the housing 100. The selection and installation of the flange 110 need to ensure the sealing and connection strength with the housing 100 to prevent leakage and other problems during subsequent use. At the same time, when installing the flange 110, attention should also be paid to its directionality to ensure smooth connection with the gas pipeline.

[0080] Step 20: Fill the accommodating space 102 with the heat conducting member 108 and the adsorbent 104 After the first flange 110 is installed, the heat transfer element 108 and the adsorbent 104 need to be filled into the accommodation space 102 in the housing 100. The heat transfer element 108 helps heat to be transferred more efficiently inside the adsorption assembly, while the adsorbent 104 is a key material for adsorbing and separating helium-3. During the filling process, it is necessary to ensure that the heat transfer element 108 and the adsorbent 104 are evenly distributed and fill the entire accommodation space 102 to ensure the best heat transfer and adsorption effect.

[0081] Step 30: Install flange 110 on the other end of housing 100 After filling the accommodation space 102, the operator needs to install the flange 110 at the other end of the housing 100. This step is similar to step 10, and it is also necessary to ensure the sealing and connection strength between the flange 110 and the housing 100. After installation, a closed accommodation space 102 will be formed between the two flanges 110 for subsequent helium-3 extraction work.

[0082] Step 40: Heat exchange between the external refrigerant and the heat exchange unit 106 The last step is to exchange heat with the heat exchange part 106 through the external refrigerant. In this step, the operator needs to connect the gas pipeline to the two flanges 110 so that the helium isotope mixture can be passed into the accommodation space. The design of the heat exchange part 106 enables the refrigerant to fully exchange heat with the heat transfer element 108 and the adsorbent 104 in the accommodation space 102, thereby realizing the cooling and heating functions of the adsorption component. By controlling the temperature and flow of the refrigerant, the operator can accurately control the temperature environment inside the adsorption component to optimize the adsorption efficiency of helium-3.

[0083] In the embodiment of the present invention, thermal conductive silicone grease and a 0.01 mm thick high-purity indium sheet may be applied on the heat exchange portion 106 to be in direct contact with the external refrigerant.
