Description

Technical Field

[0001] The invention belongs to the technical field of rare gas extraction and utilization equipment, and in particular relates to a device for extracting and utilizing rare gas in carbonate rocks. Background Art

[0002] Rare gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), etc. Rare gases He, Ne, Ar, Kr, Xe are a group of inert geochemical tracers, and their original composition does not depend on microbial activity, chemical reactions, or changes in oxygen fugacity. In addition, the concentration of rare gases in geological samples (such as rocks, groundwater, and natural gas) is extremely low, and they have extremely high sensitivity, which can trace very small changes in geological fluids during complex geological processes. At the same time, there are three main sources of rare gases in underground fluids: the atmosphere, the crust, and the mantle. The rare gases from these sources have significantly different elemental and isotopic compositions, so rare gases are good material source tracers. Rare gas geochemistry has been applied to many fields of earth science, including crust-mantle material exchange, volcanic / seismic activity, oil / natural gas resources, fluid-rock interaction / mineral resources, mantle source rocks / mantle degassing, subduction zones / serpentinization, paleoclimate / environmental evolution, carbon dioxide geological storage, groundwater pollution tracing and many other earth science research fields.

[0003] Although the current rare gas isotope analysis platform can test solid samples, most of them are based on the principle of high-temperature melting analysis. For example, "Zhang Wen. Research on the accumulation mechanism of strategic helium resources in Guanzhong and the northern margin of Qaidam [D]. China University of Mining and Technology (Beijing), 2019", "Wang Ying, He Huaiyu, Zhang Chuantong, et al. Method for determining rare gases in trace meteorite laser melting samples [J]. Acta Petrologica Sinica, 2018, 34(11)" and other research results.

In addition, the content of rare gas components in carbonate samples may account for only a few percent or even lower, which will seriously affect the analysis results of rare gas components.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] Carbonate rock samples are not suitable for high temperature melting analysis because carbonate rock will release a large amount of volatiles, such as CO 2 , H2 S, organic matter, etc. These volatiles often exceed the purification limit of the instrument and cannot be completely removed. In addition, the content of rare gas components in carbonate samples may only account for a few percent, which will seriously affect the analysis results of rare gas components and lead to low utilization rate of carbonate rock samples. It may even cause serious pollution to the entire rare gas isotope analysis platform.

[0034] Based on the above reasons, the present invention designs a device for extracting and utilizing rare gases in carbonate rocks using the following principles: the diameter of helium molecules is approximately 0.218 nanometers, the diameter of neon molecules is approximately 20.4 nanometers, the diameter of argon molecules is approximately 0.34 nanometers, the diameter of krypton molecules is approximately 0.6 nanometers, and the diameter of xenon molecules is approximately 0.22 nanometers. These rare gases are basically nanometer-level molecular diameters; the particle size of carbonate rock samples obtained by mechanical crushing can be controlled above the micron level.

[0035] In the present invention, the device for extracting and utilizing rare gases in carbonate rocks refers to Figure 1 , including a container body 1, which is a sealed container, and is used to connect to the rare gas purification and detection equipment through a pipeline 8. A gas-solid barrier component 2 and a mechanical crushing component 3 are arranged inside the container body 1. The gas-solid barrier component 2 is provided with a filter hole 21, and the diameter of the filter hole 21 is at the micron level, which is used to allow the rare gas components to pass through and intercept the carbonate rock sample particles obtained by the mechanical crushing method. The gas-solid barrier component 2 divides the container body 1 into an upper chamber 11 and a lower chamber 12. Specifically, the upper chamber 11 is connected to the rare gas purification and detection equipment through a pipeline 8. The mechanical crushing component 3 is arranged at the bottom of the gas-solid barrier component 2, and the mechanical crushing component 3 is used to crush the carbonate rock sample, and make the particle size of the carbonate rock sample particles above the micron level. After mechanical crushing, the rare gas components in the carbonate rock sample are fully volatilized, and according to the principle of free diffusion of the rare gas components, the rare gas components diffuse into the upper chamber 11 through the filter holes 21 of the gas-solid barrier component 2, and the solid carbonate rock sample particles obtained by crushing remain in the lower chamber 12 due to the barrier effect of the gas-solid barrier component 2. The gas-solid barrier component 2 has elasticity, so when the carbonate rock sample is mechanically crushed, the mechanical vibration drives the gas-solid barrier component 2 to vibrate, which can shake off the carbonate rock sample particles attached to the gas-solid barrier component 2, that is, while satisfying the passage of the rare gas components, it prevents the gas-solid barrier component 2 from being blocked.

[0036] In addition, the mechanical crushing component 3 includes a motor 31, a crushing assembly and a crushing chamber 32. The crushing chamber 32 is connected to the bottom of the gas-solid barrier component 2, and the motor 31 is arranged inside the crushing chamber 32. A particle deposition device 5 is arranged inside the crushing chamber 32. The particle deposition device 5 is located above the motor 31 and the crushing assembly. The particle deposition device 5 includes a connecting rope 51 and a sphere 52. The connecting rope 51 is connected to the inner wall of the crushing chamber 32, and the sphere 52 is connected to the connecting rope 51. Because when the mechanical crushing component 3 crushes the carbonate rock sample, when the carbonate rock sample particles are first generated, the carbonate rock sample particles are flying, that is, they occupy the space of the lower chamber 12, which will block the rare gas components from diffusing to the chamber 11. By setting the particle deposition device 5, the carbonate rock sample particles can be prevented from flying.

[0037] The device for extracting and utilizing rare gases from carbonate rocks provided by the present invention not only avoids the large amount of CO generated by high-temperature melting method, but also 2 , H 2 S, organic matter and other impurity components, and can also separate the solid carbonate rock sample particles from the rare gas components, effectively extracting the rare gas components from the carbonate samples so that they can be effectively utilized without being interfered by impurity gases, and also avoiding serious contamination of the entire rare gas isotope analysis platform.

[0038] The present invention illustrates the specific structure and working principle through the following embodiments.

[0039] Example 1

[0040] A device for extracting and utilizing rare gases from carbonate rocks, referring to Figure 1 , comprising a container body 1, which is a sealed container for connecting to the rare gas purification and detection equipment. The container body 1 can be cylindrical or cubic. Preferably, the container body 1 is made of a material that can be evacuated to facilitate the evacuation operation of the rare gas purification and detection equipment.

[0041] A gas-solid barrier component 2 is provided inside the container body 1, and the gas-solid barrier component 2 divides the container body 1 into an upper chamber 11 and a lower chamber 12. A plurality of filter holes 21 are provided on the gas-solid barrier component 2, and the diameter of the filter hole 21 is in the micron level, which is used to allow the rare gas components to pass through and intercept the carbonate sample particles obtained by the mechanical crushing method. In this embodiment, the number of filter holes 21 is at least 50, and the preferred number is 50 to 1000. The diameter of the filter hole 21 is any value between 1 micron and 800 microns, which are all greater than the molecular diameters of rare gas components such as He, Ne, Ar, Kr, and Xe, allowing rare gas components such as He, Ne, Ar, Kr, and Xe to pass through. The common mechanical crushing method can crush the carbonate sample into carbonate sample particles with a particle size greater than the diameter of the filter hole 21, such as the carbonate sample particle size is any value between 900 microns and 500 mm.

[0042] The gas-solid barrier component 2 is elastic. When the carbonate rock sample is mechanically crushed, the mechanical vibration drives the gas-solid barrier component 2 to vibrate, which can shake off the carbonate rock sample particles attached to the gas-solid barrier component 2, that is, while satisfying the passage of rare gas components, it prevents the gas-solid barrier component 2 from being blocked.

[0043] Further, in this embodiment, see Figure 2 The cross-sectional shape and area of ​​the gas-solid barrier component 2 are equal to the shape and area of ​​the container body 1, that is, the gas-solid barrier component 2 completely blocks the container body 1, and the upper chamber 11 and the lower chamber 12 can only be connected through the filter hole 21. This can prevent the carbonate sample particles from diffusing into the upper chamber 11 from other places.

[0044] In order to better bear the load, the gas-solid barrier component 2 includes a fixed part 22 and a breathable part 23. The breathable part 23 is provided with a filter hole 21. The fixed part 22 is fixedly connected to the inner wall of the container body 1, and the bottom of the fixed part 22 is used to connect to the crushing chamber 32. The breathable part 23 is arranged at the center of the fixed part 22.

[0045] In order to collect more rare gas components, the crushing chamber 32 surrounds the air-permeable part 23. For example, the fixed part 22 is set to be annular, the air-permeable part 23 is set to be circular, the outer edge of the fixed part 22 is fixedly connected to the inside of the container body 1, and the inner edge is fixedly connected to the outer edge of the air-permeable part 23. The connection is sealed with a sealant or a sealing gasket. The top edge of the crushing chamber 32 is detachably connected or fixedly connected to the lower surface of the connecting plate 33, and the upper surface of the connecting plate 33 is fixedly connected to the connection between the fixed part 22 and the air-permeable part 23, so that the edge of the crushing chamber 32 and the edge of the air-permeable part 23 are connected through the connecting plate 33, and the connection between the fixed part 22 and the air-permeable part 23 is flush with the outer edge of the connecting plate 33.

[0046] A mechanical crushing component 3 is also provided inside the lower chamber 12. The mechanical crushing component 3 is located below the gas-solid barrier component 2, and the bottom of the fixing portion 22 is connected to the mechanical crushing component 3. The mechanical crushing component 3 is used to crush the carbonate rock sample, and the particle size of the carbonate rock sample particles is above the micron level. In addition, the mechanical crushing component 3 adopts electromagnetic crushing equipment, blade crushing equipment, hammer crushing equipment, cone crushing equipment or impact crushing equipment. As long as the carbonate rock sample can be crushed into particles above the micron level, the present invention is applicable.

[0047] Exemplarily, the mechanical crushing component 3 includes a motor 31, a crushing assembly and a crushing chamber 32. The crushing chamber 32 is connected to the bottom of the fixed part 22. The motor 31 is arranged inside the crushing chamber 32. The crushing assembly is a blade 33. The blade 33 is installed on the motor 31, and the carbonate rock sample is crushed by the blade 33. After crushing, the rare gas components in the carbonate rock sample are fully volatilized, and according to the principle of free diffusion of the rare gas components, the rare gas components diffuse into the upper chamber 11 through the gas-solid barrier component 2, and the solid carbonate rock sample particles obtained by crushing remain in the lower chamber 12 due to the barrier effect of the gas-solid barrier component 2.

[0048] In addition, refer to Figure 3 and Figure 4 In this embodiment, a particle deposition device 5 is provided inside the crushing chamber 32. The particle deposition device 5 is located above the motor 31 and the crushing assembly. The particle deposition device 5 is used to deposit carbonate rock sample particles.

[0049] Furthermore, the particle deposition device 5 includes a connecting rope 51 and a sphere 52. The connecting rope 51 is fixed to the inner wall of the crushing chamber 32. The sphere 52 is fixedly connected to the connecting rope 51. A deposition component is arranged on the sphere 52. The diameter of the deposition component is in the micrometer level or centimeter level.

[0050] The deposition component is a deposition hole 53, the diameter of the deposition hole 53 is in the centimeter level, such as 1 cm to 2 cm, and the particle size is much larger than the diameter of carbonate rock sample particles and rare gas components. These deposition holes 53 can catch carbonate rock sample particles that fall due to gravity.

[0051] Furthermore, the deposition hole 53 is disposed in the upper half of the sphere 52 and is a hemispherical hole. Since the volatilized rare gas components are released into the upper chamber 11 and diffuse upward, the surface of the lower half of the sphere 52 is configured as a smooth surface, which can reduce the obstruction of the rare gas components. The carbonate rock sample particles move downward under the action of gravity and can be caught by the deposition hole 53 and gathered there, thereby reducing the influence of the carbonate rock sample particles on the activity of the rare gas components.

[0052] Furthermore, the particle deposition device 5 is provided with at least two layers, and the spheres 52 are arranged in an alternating manner. The surfaces of the spheres 52 of adjacent layers are in contact. In this way, when vibrating, the spheres 52 of adjacent layers can vibrate against each other, and when the vibration stops, a thick network for trapping carbonate sample particles can be formed between the multiple layers of spheres 52, which traps carbonate sample particles with large particle sizes and prevents carbonate sample particles from being deposited at the bottom of the crushing chamber 32, while the rare gas components can pass through the thick network smoothly due to their small molecular diameters.

[0053] The above-mentioned particle deposition device 5 also has the following advantages: the motor 31 works intermittently, and when it is crushing, the vibration can also drive the particle deposition device 5 to vibrate, which can assist in crushing the carbonate rock sample. When the mechanical crushing is paused, the crushed carbonate rock sample particles can be deposited on the particle deposition device 5 to avoid falling into the bottom of the crushing chamber 32. Then, the rare gas components in the carbonate rock sample particles at the bottom of the crushing chamber 32 and deposited on the particle deposition device 5 can diffuse toward the upper chamber 11, thereby increasing the diffusion area and improving the diffusion efficiency.

[0054] The above structure avoids the large amount of CO generated by high temperature melting method. 2 , H 2 S, organic matter and other impurity components, and can also separate the solid carbonate rock sample particles from the rare gas components, effectively extracting the rare gas components from the carbonate samples so that they can be effectively utilized without being interfered by impurity gases, and also avoiding serious contamination of the entire rare gas isotope analysis platform.
