Description

Technical Field

[0001] The present 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] Noble gases, including helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe), are a group of inert geochemical tracers whose original composition is independent of microbial activity, chemical reactions, or changes in oxygen fugacity. Furthermore, their concentrations in geological samples (such as rocks, groundwater, and natural gas) are extremely low, giving them exceptional sensitivity and the ability to track even the smallest changes in geological fluids during complex geological processes. Furthermore, noble gases in subsurface fluids originate primarily from three sources: the atmosphere, the crust, and the mantle. These gases have distinct elemental and isotopic compositions, making them excellent 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.

[0004] Carbonate rock samples are not suitable for high-temperature melting analysis. This is because when using high-temperature melting analysis, carbonate rock samples release a large amount of volatiles, such as CO2, H2S, and organic matter. These volatiles often exceed the purification limit of the instrument and cannot be completely removed. In addition, the content of noble gas components in carbonate samples may only account for a few percent, or even less, which will seriously affect the analysis results of the noble gas components.

[0012] Preferably, in the above-mentioned device for extracting and utilizing rare gases from carbonate rocks, the deposition component is a deposition hole with a diameter of the centimeter level; or the deposition component is a convex hillock with a diameter of the micrometer level.

[0013] Preferably, in the above-mentioned device for extracting and utilizing rare gases from carbonate rocks, the diameter of the filter holes is 1 micron to 800 microns; the diameter of the sedimentation holes is 1 centimeter to 2 centimeters; and the diameter of the convex hillocks is 1 micron to 10 microns.

[0014] Preferably, in the above-mentioned device for extracting and utilizing rare gases from carbonate rocks, the particle deposition device is provided with at least two layers, and the spheres in adjacent layers are arranged in a staggered manner.

[0015] Preferably, in the apparatus for extracting and utilizing rare gases from carbonate rocks, the spheres in adjacent layers are in contact with each other. That is, when two layers of spheres are staggered, one sphere is in contact with the two adjacent spheres on either side thereof.

[0018] The crushing chamber is arranged at the bottom of the ventilating portion, and the edge of the crushing chamber is connected to the edge of the ventilating portion via a connecting plate, and the connection between the fixing portion and the ventilating portion is flush with the outer edge of the connecting plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the container body is the main structure, and the mechanical crushing component is used to mechanically crush the carbonate rock sample. The released rare gas components flow from the lower chamber through the filter hole into the upper chamber so as to be utilized. When the carbonate rock sample is mechanically crushed, the mechanical vibration of the motor drives the crushing chamber and the gas-solid barrier component to vibrate in sequence, which can shake off the carbonate rock sample particles attached to the gas-solid barrier component, that is, while satisfying the passage of the rare gas components, it prevents the gas-solid barrier component from being blocked. In addition, the particle deposition device is used to deposit carbonate rock sample particles. Because when the mechanical crushing component crushes the carbonate rock sample and carbonate rock sample particles are just beginning to be generated, the carbonate rock sample particles are flying, that is, they occupy the space in the lower chamber and will block the rare gas components from diffusing into the chamber. By setting up a particle deposition device, the carbonate rock sample particles can be prevented from flying excessively.

[0029] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below with reference to specific embodiments and drawings.

[0030] In the description of the present invention, unless otherwise specified, all reagents used are commercially available and all methods used are conventional techniques in the art.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and 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. This is because high-temperature melting releases large amounts of volatiles, such as CO2, H2S, and organic matter. These volatiles often exceed the instrument's purification limits and cannot be completely removed. Furthermore, the noble gas content in carbonate samples may only account for a few percent, which can severely affect the analysis of noble gas components, resulting in low carbonate sample utilization and even serious contamination of the entire noble 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 basically have molecular diameters at the nanometer level; the particle size of carbonate rock samples obtained by mechanical crushing can be controlled to 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, which 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 provided 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. 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 noble gas components in the carbonate rock sample are fully volatilized. Based on the principle of free diffusion of noble gas components, the noble gas components diffuse into the upper chamber 11 through the filter pores 21 of the gas-solid barrier component 2. The solid carbonate rock sample particles obtained by crushing remain in the interior of the lower chamber 12 due to the barrier effect of the gas-solid barrier component 2. 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. In other words, it can prevent the gas-solid barrier component 2 from clogging while ensuring the passage of noble gas components.

[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 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 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, the carbonate rock sample particles are initially generated. The carbonate rock sample particles are flying, that is, they occupy the space in the lower chamber 12 and will block the diffusion of rare gas components into the chamber 11. By providing the particle deposition device 5, the flying of carbonate rock sample particles can be prevented.

[0037] The device for extracting and utilizing rare gases from carbonate rocks provided by the present invention not only avoids the generation of large amounts of impurity components such as CO2, H2S, and organic matter by the high-temperature melting method, but also can separate solid carbonate rock sample particles from the rare gas components, effectively extracting the rare gas components from the carbonate sample so that they can be effectively utilized without being interfered with 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 The apparatus comprises a container body 1, which is a sealed container for connection to the noble gas purification and detection equipment. The container body 1 can be cylindrical or cubic in shape. Preferably, the container body 1 is made of a vacuum-capable material to facilitate vacuuming operations of the noble gas purification and detection equipment.

[0041] The container body 1 is provided with a gas-solid barrier 2, which divides the container body 1 into an upper chamber 11 and a lower chamber 12. The gas-solid barrier 2 is provided with a plurality of filter holes 21, each with a diameter in the micrometer range, to allow the passage of noble gas components while retaining carbonate sample particles obtained by mechanical crushing. In this embodiment, the number of filter holes 21 is at least 50, and preferably 50 to 1000. The diameter of the filter holes 21 ranges from 1 micrometer to 800 micrometers, which are larger than the molecular diameters of noble gas components such as He, Ne, Ar, Kr, and Xe, allowing these components to pass through. Conventional mechanical crushing methods, however, can crush carbonate samples into particles larger than the diameter of the filter holes 21, for example, particles with a diameter ranging from 900 micrometers to 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 allowing the rare gas components to pass through, 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 those 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 communicate through the filter hole 21. This prevents carbonate sample particles from diffusing into the upper chamber 11 from other places.

[0044] In order to better bear the weight, 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 portion 23. For example, the fixed portion 22 is set to be annular, and the air-permeable portion 23 is set to be circular. The outer edge of the fixed portion 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 portion 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 portion 22 and the air-permeable portion 23, so that the edge of the crushing chamber 32 and the edge of the air-permeable portion 23 are connected through the connecting plate 33, and the connection between the fixed portion 22 and the air-permeable portion 23 is flush with the outer edge of the connecting plate 33.

[0046] A mechanical crushing unit 3 is also provided within the lower chamber 12. This unit is located below the gas-solid barrier 2 and is connected to the bottom of the fixed portion 22. This unit is used to crush the carbonate rock sample to a particle size of micrometers or larger. Alternatively, the mechanical crushing unit 3 may employ electromagnetic crushing equipment, blade crushing equipment, hammer crushing equipment, cone crushing equipment, or impact crushing equipment. Any method capable of crushing carbonate rock samples into micrometer-sized particles or larger is suitable for use in the present invention.

[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 portion 22. The motor 31 is disposed within the crushing chamber 32. The crushing assembly is a blade 33, which is mounted on the motor 31 and is used to crush the carbonate rock sample. After crushing, the noble gas components in the carbonate rock sample are fully volatilized. Based on the principle of free diffusion of noble gas components, the noble gas components diffuse into the upper chamber 11 through the gas-solid barrier component 2. 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 provided on the sphere 52. The diameter of the deposition component is in the micrometer level or centimeter level.

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

[0051] Furthermore, the deposition hole 53 is provided 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 provided as a smooth surface, which can reduce the obstruction of the rare gas components. In addition, the carbonate rock sample particles move downward under the action of gravity and can be caught by the deposition hole 53 and gathered there, 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 pattern. The surfaces of the spheres 52 in adjacent layers are in contact. Thus, when vibrating, the spheres 52 in adjacent layers can vibrate against each other. When vibration stops, a thick network is formed between the multiple layers of spheres 52, trapping carbonate sample particles. This network traps large carbonate sample particles and prevents them from settling at the bottom of the pulverization chamber 32. However, the rare gas components, due to their small molecular diameters, can pass smoothly through this thick network.

[0053] The above-mentioned particle deposition device 5 also has the following advantages: the motor 31 works intermittently. 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 in the particle deposition device 5 can diffuse toward the upper chamber 11, increasing the diffusion area and improving the diffusion efficiency.

[0054] The above structure not only avoids the large amount of impurity components such as CO2, H2S, and organic matter produced by the high-temperature melting method, but also can separate the solid carbonate rock sample particles from the rare gas components, effectively extracting the rare gas components from the carbonate sample so that they can be effectively utilized without being interfered by impurity gases, and also avoids serious contamination of the entire rare gas isotope analysis platform.

[0057] The difference between this embodiment and embodiment 1 is that a convex hillock 54 is provided on the sphere 52. Figure 5 The diameter of the convex hillock 54 is in the micron level, such as 1 micron to 10 microns. As a “crystal nucleus”, it can gather carbonate rock sample particles, which is beneficial to the deposition of carbonate rock sample particles on the sphere 52.

[0058] Example 3

A mechanical crushing component 3 is provided at the bottom of the gas-solid barrier component 2. The mechanical crushing component 3 is used to mechanically crush carbonate rocks.

[0060] The difference between this embodiment and embodiment 1 is that, referring to Figure 6 In this embodiment, in order to enhance the mechanical vibration effect of the mechanical crushing component 3 while taking into account the load-bearing effect and better prevent the gas-solid barrier component 2 from being blocked, an elastic layer 4 is further provided between the mechanical crushing component 3 and the inner wall of the container body 1. The elastic layer 4 is a spring or elastic rubber layer. The elastic layer 4 plays the role of load bearing and vibration.

[0061] More specifically, the crushing chamber 32 is located at the bottom of the ventilating portion 23, and the edges of the crushing chamber 32 and the ventilating portion 23 are connected by a connecting plate 33.
