Description

Technical Field

[0001] The present invention relates to the technical field of gas production devices, and in particular to a gas-water separation device used for gas production in a salt cavern gas storage. Background Art

[0002] Salt caverns are artificial underground caverns formed through solution mining within thick salt deposits or domes. Their size and shape vary depending on the geological conditions. Because they are buried deep underground and salt, under high temperature and pressure, exhibits a certain plasticity, allowing it to heal automatically under certain cracks, making them excellent sealed storage reservoirs. Salt caverns provide a vast and secure underground space for storing materials that do not dissolve salt. They are primarily used to store liquid and gaseous hydrocarbons and related products, a primary use that continues to this day. This is particularly true for oil and natural gas. The vast storage space provided by salt caverns allows excess gas in the transmission system to be stored during periods of low demand, allowing it to be pumped out to supplement supply during peak demand periods, thus providing a significant regulatory advantage.

[0003] In related technologies, during the gas extraction process through salt cavern gas storage, some liquid water, particles and other debris will exist in the gas pipeline. These impurity particles will cause wear of natural gas pipelines, valves and other equipment during the flow process. Therefore, separation equipment is required for separation during gas extraction. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present application more apparent, example embodiments according to the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application described in this application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this application.

[0021] like Figures 1-4 As shown, an embodiment of the present application provides a gas-water separation device for gas production in a salt cavern gas storage, the device comprising: a gas transmission pipe 1, a sleeve 2, a separation component, a drive component 3 and a collector 4.

[0022] Among them, the sleeve 2 is sleeved on the outside of the gas pipe 1, and the gas pipe 1 and the sleeve 2 are connected. The separation component includes a separation cylinder 5 rotatably installed in the sleeve 2 and a blade 52 arranged in the separation cylinder 5. One end of the sleeve 2 is connected to the gas pipe 1, and the other end is provided with an exhaust port 53. The side wall of the separation cylinder 5 is provided with a drain port 54, and the bottom of the sleeve 2 is provided with a hole corresponding to the drain port 54. The driving component 3 is used to drive the separation cylinder 5 to rotate. The outside of the separation cylinder 5 is provided with a connecting ring 51, and the inside of the sleeve 2 is provided with an annular groove that cooperates with the connecting ring 51. The separation cylinder 5 is rotatably connected to the sleeve 2 through the connecting ring 51. The driving component 3 is arranged on the outside of the sleeve 2 and drives the connecting ring 51 and the separation cylinder 5 to rotate. The collector 4 is arranged at the bottom of the sleeve 2, and the top of the collector 4 is provided with an opening that cooperates with the hole.

[0023] The separation device in the present application is provided with a structure of a sleeve 2 and a separation component. When the gas in the gas pipe 1 passes through, it will be intercepted by the blades 52 in the separation component, and impurities such as water droplets will fall into the separation cylinder 5. The separation cylinder 5 is driven by the driving component 3 to rotate, and the impurities will be sent to the collector 4 under the action of centrifugal force, thereby realizing gas-water separation and ensuring the smooth progress of gas transmission.

[0024] The driving assembly 3 includes a shell 31 arranged outside the sleeve 2 and a driving ring 32 arranged inside the shell 31. The driving ring 32 is rotatably installed on the outside of the sleeve 2. The rotation center lines of the driving ring 32 and the separation cylinder 5 coincide with each other. A first magnet 34 is provided on the inside of the driving ring 32, and a second magnet 35 is provided on the outside of the separation cylinder 5. The magnetic properties of the first magnet 34 and the second magnet 35 are opposite on the sides where they are close to each other.

[0025] Because the first magnet 34 and the second magnet 35 have opposite magnetic properties, when the drive ring 32 rotates around the sleeve 2 under the action of magnetic force, it will drive the internal separation cylinder 5 to rotate, thereby driving the separation cylinder 5. For example, the sleeve 2 in this application is made of aluminum alloy to reduce its impact on the interaction between the magnets. Therefore, during use, only the external drive ring 32 needs to be driven.

[0026] Exemplarily, the drive assembly 3 further includes a bevel gear 33 rotatably mounted on the housing 31. The outer edge of the drive ring 32 is provided with engaging teeth that mesh with the bevel gear 33. The bevel gear 33 drives the drive ring 32 to rotate. The engaging teeth on the bevel gear 33 and the drive ring 32 mesh with each other. When drive is required, only the bevel gear 33 needs to be driven. In some embodiments, the central axis of the bevel gear 33 is connected to a drive element such as a drive motor, thereby driving the bevel gear 33 to achieve drive of the separation drum 5.

[0027] In some embodiments, the blades 52 are rotatably connected to the inner wall of the separation barrel 5 , and the rotational center lines of the blades 52 , the separation barrel 5 , and the external drive ring 32 are all arranged to coincide.

[0028] The structure of the collector 4 is introduced below: illustratively, the top of the collector 4 is arranged at the bottom of the sleeve 2, and the end of the collector 4 is connected to the outer shell 31. An accommodating chamber 41 is provided in the collector 4, and the opening is connected to the accommodating chamber 41. An outlet 42 is provided at the bottom of the accommodating chamber 41, and a movable plate 44 is movably installed on the outlet 42. Specifically, a movable groove 43 is provided on the outer shell 31 at the outlet 42 at the bottom of the collector 4, and the end of the movable plate 44 is movably installed in the movable groove 43, thereby realizing a movable connection between the movable plate 44 and the bottom of the collector 4. An elastic member connected to the movable plate 44 is provided in the movable groove 43. Exemplarily, the elastic member includes a spring 45, and the two ends of the spring 45 are respectively connected to the inner wall of the movable plate 44 and the movable groove 43.

[0029] When the separator 5 is in operation, centrifugal force separates the gas and water, and the remaining liquid water and other impurities are discharged into the collector 4 through the drain port 54. The receiving chamber 41 in the collector 4 is used to accommodate water and other impurities. A movable plate 44, which is movably mounted at the bottom of the collector 4, is used to drain the water from the collector 4. When the movable plate 44 is closed, the bottom of the collector 4 is sealed, and when the movable plate 44 is opened, the bottom of the collector 4 is opened. A spring 45 in the movable groove 43 at the bottom of the movable plate 44 is used to reset the movable plate 44 after movement.

[0030] The collector 4 is also provided with a control slot 46, in which a turntable 6 is rotatably mounted. The turntable 6 is provided with an arcuate slot 65, in which a block 63 is provided. The block 63 is hingedly connected to a movable rod 64. The end of the movable plate 44 is connected to the movable rod 64. The turntable 6 is provided with a guide rod 61, which is provided with a guide slot 62. The guide rod 61 passes through the turntable 6. The turntable 6 is provided with a guide block that cooperates with the guide slot 62. The bottom of the guide rod 61 extends to the outside of the collector 4. The guide slot 62 is curved, and the curvature of the guide slot 62 is along the length direction of the guide rod 61 and toward the circumference of the guide rod 61.

[0031] A turntable 6 is rotatably mounted in the control slot 46. An arcuate slot 65 provided on the turntable 6 connects to a movable rod 64 via a block 63. The movable rod 64 is connected to the movable plate 44. When the turntable 6 rotates, the arcuate slot 65 and the block 63 drive the movable rod 64. Furthermore, a guide rod 61 and the turntable 6 cooperate with each other. The guide rod 61 is provided with a curved guide slot 62, which fits into the guide block on the turntable 6. When the guide rod 61 moves, the guide slot 62 acts on the turntable 6, converting the linear motion of the guide rod 61 into circumferential rotation of the turntable 6, thereby driving the turntable 6. The rotation of the turntable 6 drives the movable rod 64 to move, thereby driving the movable plate 44. Therefore, when the bottom of the collection chamber needs to be opened for drainage, pressing the guide rod 61 can drive the turntable 6, the movable rod 64, and the movable plate 44, thereby opening the movable plate 44 and opening the bottom of the collection chamber. After the drainage is completed, the guide rod 61 is released, and the movable plate 44 is reset under the elastic force of the spring 45 so that the movable plate 44 is closed again.

[0032] Based on this, the separation device in this application, by setting up the structure of the sleeve 2 and the separation component, will intercept the gas from the gas pipe 1 by the blades 52 in the separation component, and impurities such as water droplets will fall into the separation cylinder 5. The separation cylinder 5 is driven by the drive component 3 to rotate, and the impurities will be sent to the collector 4 under the action of centrifugal force, thereby achieving gas-water separation and ensuring the smooth progress of gas transmission. In addition, the opening and closing of the bottom of the collector 4 is also easy to control. After the collector 4 completes a period of collection, it is convenient to drain the collector 4.

[0033] The following is an introduction to the working principle of this application:

[0034] During gas extraction, liquid water and other impurities in the gas pipeline 1 are blocked by the blades 52 in the sleeve 2 and fall onto the inner wall of the sleeve 2. The sleeve 2 is driven by the drive assembly 3. During the rotation of the sleeve 2, the liquid water and other impurities on the inner wall are sent to the collector 4 at the bottom through the drain port 54 by the centrifugal force. The receiving chamber 41 in the collector 4 collects the liquid water and other impurities.

[0035] When the collector 4 contains enough water and other impurities, the turntable 6 can be driven by pressing the guide rod 61. The guide groove 62 on the guide rod 61 cooperates with the guide block on the turntable 6. Under the action of the guide rod 61 and the guide groove 62, the turntable 6 is driven. During the rotation of the turntable 6, the arc groove 65 acts on the movable rod 64, causing the movable rod 64 and the movable plate 44 to move horizontally. After the movable plate 44 moves, the bottom of the accommodating chamber 41 is opened, so that it can be used for drainage. After the drainage is completed, the guide rod 61 is released, and the movable plate 44 is reset under the action of the spring 45. After the movable plate 44 is reset, the bottom of the storage chamber is closed again, and it continues to be used for accommodating impurities.
