[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] The following describes a rock mass hydrogen production reaction sealing structure 100 capable of applying confining pressure according to an embodiment of the present invention with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a rock hydrogen production reaction sealing structure 100 capable of applying confining pressure according to an embodiment of the present invention includes: a flexible container 1, a first pipeline, a pressure container 2 and a confining pressure piece 3. The flexible container 1 includes a first box body and a first cover body. The first box body defines a reaction space 11 and one end of the first box body is open. The reaction space 11 can accommodate a test rock mass 4. The first cover body can close the open end of the first box body to seal the reaction space 11. The first pipeline is connected to the reaction space 11. The reaction fluid can flow into the reaction space 11 through the first pipeline to react with the test rock mass 4 and generate hydrogen. The pressure container 2 defines a receiving space. The flexible container 1 is arranged in the receiving space. The confining pressure piece 3 is arranged in the receiving space and is located between the flexible container 1 and the pressure container 2. The confining pressure piece 3 is used to apply confining pressure to the flexible container 1.

[0025] The reactants of the rock reaction include a test rock 4. During the rock reaction, the test rock 4 can be placed in a reaction space 11 defined by a first housing of the flexible container 1. The first housing has an open end, through which the test rock 4 can be placed into the reaction space 11. The first cover can seal the open end of the first housing to form a sealed space within the flexible container 1, which is conducive to the rock reaction and reduces the risk of leakage of hydrogen generated by the rock reaction. The flexible container 1 can deform when under pressure, so that the flexible container 1 can fit tightly against the test rock 4 to apply confining pressure to the test rock 4.

[0026] The first pipeline of the rock mass hydrogen production reaction sealing structure 100 with confining pressure can be connected to the reaction space 11. The first pipeline can be used to transport the reaction fluid into the reaction space 11. The reaction fluid and the test rock mass 4 can react chemically in the reaction space 11 to produce hydrogen.

[0027] The pressure-bearing container 2 of the rock hydrogen production reaction sealing structure 100 has a certain structural strength and rigidity, and the pressure-bearing container 2 is not easy to deform. The pressure-bearing container 2 can define a receiving space, and the flexible container 1 and the confining pressure piece 3 can be placed in the receiving space. The confining pressure piece 3 can be located between the flexible container 1 and the pressure-bearing container 2, and the volume of the confining pressure piece 3 can be changed. By increasing the volume of the confining pressure piece 3, the confining pressure piece 3 can press the flexible container 1, so that the flexible container 1 can tightly fit the test rock 4. As some embodiments of the present application, the pressure-bearing container 2 can be configured as a metal container. By configuring the pressure-bearing container 2 as a metal container, the pressure of the confining pressure piece 3 is not easy to deform the pressure-bearing container 2, or the pressure-bearing container 2 will deform slightly when subjected to the pressure of the confining pressure piece 3, so that the confining pressure piece 3 can almost completely expand towards the flexible container 1, so that the confining pressure can be more accurately applied to the flexible container 1.

[0028] In the above embodiment, by placing the flexible container 1 containing the test rock 4 in the receiving space of the pressure-bearing container 2 and applying confining pressure to the flexible container 1 by the confining pressure piece 3, the test rock 4 can react and produce hydrogen, and the rock hydrogen production reaction sealing structure 100 can have good sealing performance, which can not only make the rock reaction proceed smoothly, but also reduce the risk of hydrogen leakage generated by the reaction, improve the accuracy of the rock reaction result, and reduce the danger of the experiment.

[0029] In some embodiments of the present application, the material of the flexible container 1 is rubber, and the first cover and the first box are sealed by rubber.

[0030] The flexible container 1 can be made of rubber, which has good elasticity, good wear resistance, good chemical stability, good heat resistance, and the flexible container 1 made of rubber is not easy to be corroded by the reactants or products in the rock reaction and fail, thereby prolonging the service life of the rock hydrogen production reaction sealing structure 100.

[0031] It can be understood that the rubber will not participate in the rock reaction, so it will not affect the test results to ensure the accuracy of the test results.

[0032] The first cover and the first box can be sealed by rubber, and rubber adhesive can be applied at the connection between the first cover and the first box to seal the flexible container 1. In this way, the entire flexible container 1 can be made of rubber, which is conducive to ensuring the accuracy of the test results. Moreover, the rubber can quickly recover to its original state after deformation, so that the flexible container 1 made of rubber can be repeatedly used.

[0033] In some embodiments of the present application, the material of the flexible container 1 is fluororubber, and the first cover and the first box are sealed by fluororubber.

[0034] Among them, the flexible container 1 can be made of fluororubber, which is resistant to high temperature, oil, oxidation, heat, chemical corrosion, and atmospheric aging. Fluororubber has certain solvent resistance and good stability, so that the flexible container 1 made of fluororubber can be used for a long time without failure. The flexible container 1 is not easily corroded by the reactants or products in the rock reaction, which can further extend the service life of the rock hydrogen production reaction sealing structure 100 that can be subjected to confining pressure.

[0035] It is understandable that fluororubber will not participate in the rock reaction and therefore will not affect the test results, ensuring that the test results are more accurate.

[0036] The first cover and the first box can be sealed by fluororubber. Fluororubber adhesive can be applied at the connection between the first cover and the first box to seal the flexible container 1. In this way, the entire flexible container 1 can be made of fluororubber, which is conducive to ensuring the accuracy of the experimental results.

[0037] In some embodiments of the present invention, the first pipeline includes a first sub-pipeline and a second sub-pipeline, both of which are connected to the reaction space 11, and the reaction gas and reaction liquid can flow into the reaction space 11 through the first sub-pipeline and the second sub-pipeline respectively.

The reaction fluid includes a reaction gas and a reaction liquid, and the reaction gas and the reaction liquid may flow into the reaction space 11 through the first sub-pipeline and the second sub-pipeline, respectively. For example, if only the reaction gas is required for this experiment, the reaction gas may flow into the reaction space 11 through the first sub-pipeline. If only the reaction liquid is required for this experiment, the reaction liquid may flow into the reaction space 11 through the second sub-pipeline. If both the reaction gas and the reaction liquid are required for this experiment, the reaction gas may flow into the reaction space 11 through the first sub-pipeline, and the reaction liquid may flow into the reaction space 11 through the second sub-pipeline.

[0039] The reaction gas and reaction liquid can react with the test rock 4 in the reaction space 11. By setting up the first sub-pipeline and the second sub-pipeline, an appropriate amount of reaction gas and / or reaction liquid can be transported into the reaction space 11 according to experimental requirements, so that the rock hydrogen production reaction sealing structure 100 with confining pressure proposed in this application can meet various experimental needs. In addition, by allowing the reaction gas and reaction liquid to flow into the reaction space 11 through different pipelines, the risk of mutual contamination between the reaction gas and reaction liquid can be reduced.

[0040] As some embodiments of the present application, the test rock mass 4 can be perforated, or the test rock mass 4 itself can have cracks, so that the reaction gas and reaction liquid can enter the test rock mass 4, so as to increase the contact area between the reactants, thereby accelerating the reaction rate and improving the degree of reaction.

[0041] In some embodiments of the present application, the flexible container 1 and the pressure container 2 may have corresponding first mounting holes and corresponding second mounting holes. The first sub-pipeline may be provided through the first mounting holes of the flexible container 1 and the pressure container 2, and the second sub-pipeline may be provided through the second mounting holes of the flexible container 1 and the pressure container 2, so that the reaction gas and the reaction liquid can flow into the reaction space 11 through the first sub-pipeline and the second sub-pipeline, respectively.

This arrangement enables the rock mass hydrogen production reaction sealing structure 100 that can apply confining pressure to test rock masses 4 of different shapes to ensure that the rock mass reaction proceeds smoothly.

[0044] As some embodiments of the present application, there can be four confining pressure pieces 3, and the four confining pressure pieces 3 are respectively arranged on the left side, right side, front side and rear side of the flexible container 1; or, there can be six confining pressure pieces 3, and the six confining pressure pieces 3 are respectively arranged on the upper side, lower side, left side, right side, front side and rear side of the flexible container 1, so as to apply confining pressure to all directions of the flexible container 1, thereby making the flexible container 1 fit tightly to the test rock mass 4 to apply confining pressure to the test rock mass 4.

[0045] In some embodiments of the present invention, the rock hydrogen production reaction sealing structure 100 capable of applying confining pressure further includes: a second pipeline and a pressure medium storage container, the confining pressure member 3 is constructed as a pressure pillow, the second pipeline is connected between the pressure medium storage container and the pressure pillow, and the pressure medium can flow into the pressure pillow through the second pipeline so that the pressure pillow applies confining pressure to the flexible container 1.

[0046] The second pipeline of the hydrogen production reaction sealing structure of the rock mass with applied confining pressure 100 can be used to connect a pressure medium storage container and a pressure pillow, the pressure medium storage container can store a pressure medium (for example, but not limited to, hydraulic oil), and the pressure medium can flow from the pressure medium storage container to the pressure pillow through the second pipeline to make the pressure pillow expand, and the expanded pressure pillow can apply confining pressure to the test rock mass 4 in the flexible container 1 to make the rock mass reaction proceed smoothly.

[0047] In some embodiments of the present application, the hydrogen production reaction sealing structure of the rock mass with applied confining pressure 100 further comprises a pressure sensor connected with the pressure pillow and used to detect the pressure in the pressure pillow.

[0048] The pressure sensor can be used to detect the pressure in the pressure pillow, the pressure sensor can be connected with the pressure pillow, and the pressure sensor can be provided with a display device, so that the experimenter can obtain the pressure in the pressure pillow in real time through the display device to control the confining pressure applied by the pressure pillow to the flexible container 1, so that the experiment is controllable, which is beneficial to improve the accuracy of the experiment and make the rock mass reaction proceed smoothly.

[0049] In some embodiments of the present application, the material of the pressure-bearing container 2 is metal, and the pressure-bearing container 2 can bear the reaction force of the confining pressure piece 3.

[0050] The pressure-bearing container 2 can be made of metal, and the metal pressure-bearing container 2 has a certain structural strength and rigidity, so that the pressure-bearing container 2 can bear a large enough reaction force of the confining pressure piece 3, so that the confining pressure piece 3 almost completely expands to one side of the flexible container 1, so that the pressure of the confining pressure piece 3 is accurately applied to the flexible container 1, which can more accurately apply confining pressure to the flexible container 1, so that the rock mass reaction experiment proceeds smoothly.

[0053] In some embodiments of the present invention, the rock mass hydrogen production reaction sealing structure 100 with confining pressure also includes: a fourth pipeline and a collection container. The fourth pipeline is connected between the reaction space 11 and the collection container. The collection container is used to collect hydrogen generated by the reaction of the test rock mass 4.
