Description

Technical Field

[0001] This application relates to the technical field of hydrates, and more particularly, to an apparatus for forming hydrates by explosive liquid water atomization. Background Art

[0002] Natural gas has a high energy density and is widely used in economic development and daily life. Currently, the uneven regional consumption of natural gas worldwide is increasing rapidly, so there is an urgent need for efficient natural gas storage and transportation technologies. Liquefied natural gas (LNG) is a widely used form in current natural gas transportation, but LNG requires high pressure (20 MPa) and low temperature (-162 °C) conditions, which means huge energy consumption and some potential safety risks. In the past decade, natural gas transportation and storage technologies based on hydrate technology have become a hot issue of concern to researchers.

[0003] Gas hydrates are compounds composed of water molecules and gas molecules under high pressure and low temperature conditions. Under appropriately low temperature and high pressure conditions, water molecules form cage-like structures with different shapes and sizes through hydrogen bond bonding, and different types of gas molecules are trapped in this structure to form gas hydrates. Most of the component gases of natural gas can form hydrates, including methane, carbon dioxide, hydrogen and other gases with similar molecular sizes. In addition, some small molecule hydrocarbon gases such as neohexane (NH), tetrahydrofuran (THF) and other hydrocarbon gases with similar molecular sizes can also form hydrates.

[0004] Compared with natural gas liquefaction (LNG), the conditions required for hydrate formation are much milder. For example, at 275.15 K, the pressure required for methane hydrate formation is 3.2 MPa. Therefore, hydrate technology is more economical and environmentally friendly for the transportation and storage of natural gas. In addition, the energy density of gas hydrates is very high, and 1 volume of hydrate can release about 170 volumes of gas under standard conditions. However, the hydrate nucleation process has random characteristics and is accompanied by a long induction period before nucleation. This means that generally, the formation efficiency of hydrates is low. After hydrates are formed, the hydrates formed at the water-gas interface will significantly reduce the gas permeability. Therefore, during the growth stage after hydrate nucleation, the mass transfer ability of the gas will gradually decrease significantly. This means that generally, the final energy storage capacity of hydrates is low. Therefore, although gas hydrates have great potential in natural gas storage and transportation, the problems of slow formation efficiency and low final energy storage capacity in the process of forming hydrates by general methods limit the commercial application scale of hydrate technology. Summary of the Invention

[0005] The present application provides an explosive liquid water atomization device for forming hydrates, which can improve the efficiency of hydrate formation and the conversion efficiency of liquid water to hydrates.

[0006] In a first aspect, an embodiment of the present invention provides an explosive liquid water atomization device for forming hydrates, comprising:

[0007] A reactor with a high-pressure environment inside and having a high-temperature zone and a low-temperature zone that communicate with each other;

[0008] A water-holding component disposed inside the reactor and communicating with the high-temperature zone; and

[0009] A high-pressure gas release component connected to the water-holding component and releasing high-pressure gas to the water-holding component, so that the liquid water in the water-holding component is atomized into droplets and enters the low-temperature zone from the high-temperature zone;

[0010] Wherein, the temperature in the high-temperature zone is higher than zero degrees Celsius, and the temperature in the low-temperature zone is lower than zero degrees Celsius.

[0011] During the above implementation process, the high-pressure gas release component operates to instantaneously release high-pressure gas to the water-holding component, which explosively atomizes the liquid water in the water-holding component into droplets; the instantaneously excited droplets continue to fly forward and pass through the high-temperature zone and the low-temperature zone in sequence; due to the high-pressure environment inside the reactor, when the droplets pass through the high-temperature zone, the nucleation process of hydrates will be completed instantaneously; subsequently, flying into the low-temperature zone, since the hydrates have already nucleated, only the growth phenomenon of hydrates will occur in the low-temperature zone and the conversion process from liquid water to ice will not occur. Therefore, the hydrates will grow rapidly in the low-temperature zone. At the same time, due to the formation of a huge number of tiny droplets during the explosive atomization of liquid water, the gas / water contact area is greatly increased, and the number of nuclei during hydrate nucleation also increases significantly. Finally, the hydrate formation reaction can be completed in an extremely short time (seconds or minutes), and a very high liquid water-hydrate conversion efficiency is ensured. Further, there are two temperature intervals, high and low, formed inside the reactor, so that the temperature field inside the reactor decreases in a gradient manner along the axial direction, which can form a strong high-pressure convective gas inside the reactor to quickly diffuse the heat released during the nucleation and growth processes of hydrates, greatly improving the conversion rate.

[0012] In an optional embodiment, the wall surface of the reactor is provided with a first external temperature-controlled water jacket, a second external temperature-controlled water jacket, and a third external temperature-controlled water jacket at intervals;

[0013] The temperature of the first external temperature-controlled water jacket is configured to be higher than zero degrees Celsius, the temperature of the second external temperature-controlled water jacket is configured to be zero degrees Celsius, and the temperature of the third external temperature-controlled water jacket is configured to be lower than zero degrees Celsius;

[0014] A high-temperature zone is defined between the first externally controlled temperature water jacket and the second externally controlled temperature water jacket, and a low-temperature zone is defined between the third externally controlled temperature water jacket and the second externally controlled temperature water jacket.

[0015] In the above implementation process, by arranging the first externally controlled temperature water jacket, the second externally controlled temperature water jacket, and the third externally controlled temperature water jacket on the outer wall of the reactor, mutually connected and independent high-temperature and low-temperature regions are formed inside the reactor to provide temperature conditions for the nucleation and growth of hydrates; meanwhile, the temperatures of the first externally controlled temperature water jacket, the second externally controlled temperature water jacket, and the third externally controlled temperature water jacket are adjustable respectively, and can adapt to different hydrates.

[0016] In an optional implementation manner, the water-holding component includes a cylindrical structure, a first filter screen, a water-holding medium, and a second filter screen;

[0017] The cylindrical structure is arranged inside the reactor, the first filter screen, the water-holding medium, and the second filter screen are arranged inside the reactor, and the water-holding medium is located between the first filter screen and the second filter screen;

[0018] One end of the cylindrical structure is connected to the high-pressure gas release component, and the other end of the cylindrical structure communicates with the inside of the reactor.

[0019] In the above implementation process, the water-holding medium is used to store liquid water, which includes but is not limited to materials with good water absorption such as sponge, quartz sand, glass beads, ceramic powder, etc.; the first filter screen and the second filter screen fix the water-holding medium to prevent the high-pressure gas filled instantaneously from flushing the water-holding medium into the reactor and ensure the normal progress of the hydrate reaction; meanwhile, the high-pressure gas filled instantaneously will be rectified by the first filter screen and the second filter screen, which is beneficial to the atomization of the liquid water in the water-holding medium and the formation of a huge number of tiny droplets, and improves the liquid water-hydrate conversion efficiency.

[0020] In an optional implementation manner, the first filter screen is arranged in the cylindrical structure in a position-adjustable manner.

[0021] In the above implementation process, if the position of the first filter screen is adjustable, the relative position with the second filter screen can be adjusted, so as to adapt to water-holding media of different sizes.

[0022] In an optional implementation manner, the high-pressure gas release component includes a gas storage tank and an electromagnetic valve;

[0023] The gas storage tank is connected to the water-holding component through the electromagnetic valve.

[0024] In the above implementation process, when the electromagnetic valve is instantaneously opened, the high-pressure gas in the gas storage tank will be instantaneously released into the water-holding component, that is, inside the reactor, and the liquid water in the water-holding component will be explosively atomized into a huge number of tiny droplets, and the droplets will have sufficient kinetic energy to fly into the low-temperature zone to ensure the normal progress of the hydrate reaction.

[0025] In an alternative embodiment, a plurality of temperature sensors are arranged in the reactor to measure the temperatures in the high-temperature zone and the low-temperature zone.

[0026] During the above implementation process, a plurality of temperature sensors are arranged in the reactor to timely measure the temperatures in the high-temperature zone and the low-temperature zone, ensuring the normal progress of the hydrate reaction in the reactor; avoiding the occurrence of the failure of the hydrate reaction due to non-compliance with the temperature requirements.

[0027] In an alternative embodiment, a pressure sensor is arranged in the reactor.

[0028] During the above implementation process, the pressure sensor can monitor the pressure value in the reactor in real time, ensuring the normal pressure in the reactor and the normal progress of the hydrate reaction in the reactor.

[0029] In an alternative embodiment, the reactor is provided with a transparent observation window and a supplementary lighting window.

[0030] During the above implementation process, the operator can monitor the formation process of the hydrate in the reactor through the transparent observation window, ensuring the normal progress of the hydrate reaction in the reactor; at the same time, the supplementary lighting window can introduce visible light into the reactor, increasing the observation range of the operator and the visibility inside the reactor.

[0031] In an alternative embodiment, the explosive liquid water atomization to form hydrate device further includes a camera corresponding to the transparent observation window.

[0032] During the above implementation process, a camera can be installed outside the reactor, and through the transparent observation window, the whole process of the explosive atomization of liquid water and its conversion into hydrate can be recorded in all directions and from multiple perspectives.

[0033] In an alternative embodiment, the explosive liquid water atomization to form hydrate device further includes a thermostatic chamber;

[0034] The reactor and the high-pressure gas release assembly are arranged in the thermostatic chamber.

[0035] During the above implementation process, arranging the reactor and the high-pressure gas release assembly in the thermostatic chamber ensures that the ambient temperature of the reaction system is constant during the hydrate reaction process, ensuring the normal progress of the hydrate reaction.

[0048] Next, the technical solutions in the present application will be described with reference to the drawings.

[0049] This embodiment provides an explosive liquid water atomization to form hydrate device 10, which can improve the hydrate formation efficiency and the liquid water - hydrate conversion efficiency.

[0050] Please refer to Figures 1-4 , Figure 1 , which is the schematic diagram of the explosive liquid water atomization to form hydrate device 10 in this embodiment, Figure 2 , which is the cross-sectional view of the reactor 11 in this embodiment, Figure 3 , which is the schematic diagram of the water holding component 12 in this embodiment, Figure 4 , which is the top view of the reactor 11 in this embodiment.

[0051] The explosive liquid water atomization to form hydrate device 10 includes a reactor 11, a water holding component 12, and a high-pressure gas release component 13. The inside of the reactor 11 is in a high-pressure environment, and there are formed a high-temperature area 14 and a low-temperature area 15 that communicate with each other. The water holding component 12 is arranged in the reactor 11 and communicates with the high-temperature area 14. The high-pressure gas release component 13 is connected to the water holding component 12 and releases high-pressure gas to the water holding component 12, so that the liquid water in the water holding component 12 is atomized into droplets and enters the low-temperature area 15 from the high-temperature area 14.

[0052] Among them, the temperature in the high-temperature region 14 is higher than zero degrees Celsius, and the temperature in the low-temperature region 15 is lower than zero degrees Celsius.

[0053] During the above implementation process, the high-pressure gas release component 13 works, instantaneously releasing high-pressure gas to the water-holding component 12, which explosively atomizes the liquid in the water-holding component 12 into droplets; the instantaneously excited droplets continue to fly forward, passing through the high-temperature region 14 and the low-temperature region 15 in sequence. Since the inside of the reactor 11 is a high-pressure environment, when the droplets pass through the high-temperature region 14, the nucleation process of hydrates will be completed instantaneously; subsequently, flying into the low-temperature region 15, since the hydrates have already nucleated, only the growth phenomenon of hydrates will occur in the low-temperature region 15, and the transformation process from liquid water to ice will not occur. Therefore, the hydrates will grow rapidly in the low-temperature region 15. At the same time, during the process of explosively atomizing liquid water, a huge number of tiny droplets will be formed (see Figure 1 , Figure 1 indicating the range of droplets with 10a), the gas / water contact area is greatly increased, and the number of nuclei during hydrate nucleation also increases significantly. Finally, the hydrate formation reaction can be completed in an extremely short time (seconds or minutes), and a very high liquid water-hydrate conversion efficiency is ensured. Further, two temperature intervals, high and low, are formed inside the reactor 11, so that the temperature field inside the reactor 11 decreases in a gradient manner along the axial direction. In this way, a strong high-pressure convective gas can be formed inside the reactor 11, quickly diffusing the heat released during the nucleation and growth processes of hydrates, greatly improving the conversion rate. It should be noted that high-pressure gas can be filled into the inside of the reactor 11 in advance to form a high-pressure environment, which is also conducive to the nucleation of hydrates.

[0054] It should be noted that the specific temperature of the high-temperature region 14 and the specific pressure value inside the reactor 11 can be adjusted according to experimental data. For example, when producing methane hydrates, in a possible environment, the temperature of the high-temperature region 14 can be 2 degrees Celsius, and the pressure of the reactor 11 can be 3.2 MPa.

[0055] In the present disclosure, the wall surface of the reactor 11 is provided with a first external temperature-controlled water jacket 16, a second external temperature-controlled water jacket 17, and a third external temperature-controlled water jacket 18 at intervals. The temperature of the first external temperature-controlled water jacket 16 is configured to be higher than zero degrees Celsius, the temperature of the second external temperature-controlled water jacket 17 is configured to be zero degrees Celsius, and the temperature of the third external temperature-controlled water jacket 18 is configured to be lower than zero degrees Celsius. The high-temperature region 14 is defined between the first external temperature-controlled water jacket 16 and the second external temperature-controlled water jacket 17, and the low-temperature region 15 is defined between the third external temperature-controlled water jacket 18 and the second external temperature-controlled water jacket 17.

[0056] In the above implementation process, by setting the first external temperature-controlled water jacket 16, the second external temperature-controlled water jacket 17, and the third external temperature-controlled water jacket 18 on the outer wall of the reactor 11, a high-temperature zone 14 and a low-temperature zone 15 that are interconnected and independent of each other are formed inside the reactor 11, providing temperature conditions for the nucleation and growth of hydrates. At the same time, it should be noted that the temperature of the second external temperature-controlled water jacket 17 is configured to be zero degrees Celsius, which is conducive to ensuring the temperature definition of the high-temperature zone 14 and the low-temperature zone 15 and ensuring that the high-temperature zone 14 and the low-temperature zone 15 do not interfere with each other. Further, the temperatures of the first external temperature-controlled water jacket 16, the second external temperature-controlled water jacket 17, and the third external temperature-controlled water jacket 18 are adjustable respectively, and can adapt to different hydrates. It should be noted that the first external temperature-controlled water jacket 16, the second external temperature-controlled water jacket 17, and the third external temperature-controlled water jacket 18 are independent temperature control devices outside the reactor 11, which are convenient for maintenance and reduce the maintenance cost.

[0057] Please refer to Figure 1 , Figure 3 and Figure 4 , it can be known that the length of the high-temperature zone 14 in the present disclosure is shorter than the length of the low-temperature zone 15. The nucleation time of the hydrate is short. In the relatively short high-temperature zone 14, the hydrate can also complete the nucleation process, and in the relatively long low-temperature zone 15, it is conducive to the growth efficiency of the hydrate, ensuring that the generated hydrate has a high energy storage capacity. At the same time, the lengths of the high-temperature zone 14 and the low-temperature zone 15 should adapt to the distance that the initial kinetic energy of the liquid droplets can reach.

[0058] In the present disclosure, the water-holding component 12 includes a cylindrical structure 19, a first filter screen 20, a water-holding medium 21, and a second filter screen 22. The cylindrical structure 19 is arranged inside the reactor 11, the first filter screen 20, the water-holding medium 21, and the second filter screen 22 are arranged inside the reactor 11, and the water-holding medium 21 is located between the first filter screen 20 and the second filter screen 22. One end of the cylindrical structure 19 is connected to the high-pressure gas release component 13, and the other end of the cylindrical structure 19 communicates with the inside of the reactor 11.

[0059] In the above implementation process, the water-holding medium 21 is used to store liquid water, which includes but is not limited to materials with good water absorption such as sponges, quartz sands, glass beads, and ceramic powders. The first filter screen 20 and the second filter screen 22 fix the water-holding medium 21 to prevent the water-holding medium 21 from being flushed into the reactor 11 by the instantaneously charged high-pressure gas, ensuring the normal progress of the hydrate reaction. At the same time, the instantaneously charged high-pressure gas will be rectified by the first filter screen 20 and the second filter screen 22, which is conducive to the atomization of the liquid water in the water-holding medium 21 and the formation of a large number of tiny droplets, improving the liquid water-hydrate conversion efficiency. It should be noted that in this embodiment, both ends of the cylindrical structure 19 are open, one end is connected to the high-pressure gas release component 13, and the other end is connected to the second filter screen 22, and communicates with the high-temperature zone 14 through the second filter screen 22.

[0060] In the present disclosure, the first filter screen 20 is disposed in the cylindrical structure 19 in an adjustable position.

[0061] In the above implementation process, since the position of the first filter screen 20 is adjustable, the relative position with the second filter screen 22 can be adjusted, so as to adapt to water-holding media 21 of different sizes. It should be noted that in the present disclosure, the first filter screen 20 is slidably disposed in the cylindrical structure 19. Since the densities of different water-holding media 21 are different, or because the content of liquid water required for hydrates is different, the sizes of the required water-holding media 21 are different. To adapt to water-holding media 21 of different sizes, the first filter screen 20 can be slid to adjust the distance between the first filter screen 20 and the second filter screen 22. It should be noted that in a possible implementation manner, after the first filter screen 20 slides to a suitable position, it can be fixed in the cylindrical structure 19 through a fixing structure such as a bolt, so as to avoid damage to the first filter screen 20 and the water-holding media 21 caused by the offset of the first filter screen 20 after the high-pressure gas acts on the first filter screen 20.

[0062] See Figure 1 In the present disclosure, the high-pressure gas release assembly 13 includes a gas storage tank 23 and a solenoid valve 24. The gas storage tank 23 is connected to the water-holding assembly 12 through the solenoid valve 24.

[0063] In the above implementation process, the solenoid valve 24 is controlled by a PID controller. When the solenoid valve 24 is instantaneously opened, the high-pressure gas in the gas storage tank 23 will be instantaneously released into the water-holding assembly 12, that is, into the reactor 11, and the liquid water in the water-holding assembly 12 will be atomized into a huge number of tiny droplets in an explosive manner. Moreover, the dispersion trajectory of the droplets is explosive, and the gas / water contact area is greatly increased, which is beneficial to the nucleation of hydrates. At the same time, the droplets have sufficient kinetic energy to fly into the low-temperature zone 15 to ensure the normal growth of hydrates. It should be noted that see Figure 1 One end of the cylindrical structure 19 is configured with a pipeline diameter expander 25 to be connected to the gas storage tank 23.

[0064] In the present disclosure, a plurality of temperature sensors 26 are disposed in the reactor 11 to measure the temperatures of the high-temperature zone 14 and the low-temperature zone 15.

[0065] See Figure 2 .

[0066] There are eight temperature sensors 26, and every two form a group. One group of temperature sensors 26 is disposed between the first external temperature-controlled water jacket 16 and the second external temperature-controlled water jacket 17, and three groups of temperature sensors 26 are evenly spaced between the third external temperature-controlled water jacket 18 and the second external temperature-controlled water jacket 17.

[0067] During the above implementation process, multiple temperature sensors 26 are configured inside the reactor 11 to timely measure the temperatures of the high-temperature zone 14 and the low-temperature zone 15, ensuring the normal progress of the hydrate reaction inside the reactor 11; avoiding the occurrence of hydrate reaction failure due to non-compliant temperatures; meanwhile, the first external temperature-controlled water jacket 16, the second external temperature-controlled water jacket 17, and the third external temperature-controlled water jacket 18 can be timely adjusted according to the temperature data fed back by the temperature sensors 26.

[0068] In the present disclosure, a pressure sensor 27 is configured inside the reactor 11.

[0069] See Figure 2 .

[0070] There are three pressure sensors 27, and the three pressure sensors 27 are arranged evenly spaced inside the reactor 11.

[0071] The pressure sensor 27 can monitor the pressure value inside the reactor 11 in real time, ensuring the normal pressure in the reactor 11 and the normal progress of the hydrate reaction inside the reactor 11.

[0072] In the present disclosure, the reactor 11 is configured with a transparent observation window 28 and a supplementary lighting window 29.

[0073] During the above implementation process, the operator can monitor the formation process of the hydrate inside the reactor 11 through the transparent observation window 28, ensuring the normal progress of the hydrate reaction inside the reactor 11; meanwhile, the supplementary lighting window 29 can introduce visible light into the reactor 11, increasing the operator's observation range and the visibility inside the reactor 11.

[0074] Among them, one transparent observation window 28 is arranged in the high-temperature zone 14 to facilitate the observation of the nucleation process of the hydrate, and two transparent observation windows 28 are arranged in the low-temperature zone 15 to facilitate the observation of the growth process of the hydrate.

[0075] It should be noted that in a possible implementation manner, the explosive liquid water atomization to form hydrate device 10 further includes a camera corresponding to the transparent observation window 28.

[0076] During the above implementation process, a camera can be installed outside the reactor 11, and through the transparent observation window 28, the whole process of explosive atomization of liquid water and its transformation into hydrate can be recorded in all directions and from multiple perspectives.

[0077] It should be noted that in the present disclosure, a transparent observation window 28 is also configured at the end of the reactor 11 to facilitate the observation of the growth process of the hydrate from the end of the reactor 11.

[0078] See Figure 1, in the present disclosure, the device 10 for forming hydrate by explosive atomization of liquid water further includes a thermostat 30. The reactor 11 and the high-pressure gas release assembly 13 are disposed in the thermostat 30.

[0079] During the above implementation process, the reactor 11 and the high-pressure gas release assembly 13 are disposed in the thermostat 30 to ensure that the ambient temperature of the reaction system is constant during the hydrate reaction process and guarantee the normal progress of the hydrate reaction.

[0080] It should be noted that, please refer to Figure 1 , the reactor 11 can also be configured with an exhaust port 31 and a manual exhaust valve 32. By opening the manual exhaust valve 32, the gas in the reactor 11 can be discharged from the exhaust port 31.

[0081] It should be noted that the device 10 for forming hydrate by explosive atomization of liquid water described in the present disclosure has at least the following differences from the existing hydrate formation devices:

[0082] 1. The liquid water no longer forms hydrate fixed in the porous medium. Through the instantaneous impact of high-pressure gas, the liquid water contained in the water-holding medium 21 is excited into a huge number of tiny atomized droplets, and finally the hydrate formation process is completed outside the water-holding medium 21.

[0083] 2. The temperature field in the reactor 11 is no longer uniform, but is set into an independent high-temperature zone 14 and a low-temperature zone 15. The high-temperature zone 14 (above zero degree) is only used for the nucleation process of hydrate, while the low-temperature zone 15 (below zero degree) is only used for the growth of hydrate.

[0084] 3. The temperature field inside the reactor 11 is overall distributed in a gradient manner along the axial direction, causing a strong convection phenomenon of the high-pressure gas inside the reactor 11, quickly diffusing the heat released by the nucleation and growth reactions, and further greatly improving the hydrate formation reaction efficiency and the final conversion rate.
