DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present application more obvious, the example embodiments according to the present application will be described in detail 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 the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0021] like Figure 1-Figure 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 sleeve 2 is provided with an annular groove that cooperates with the connecting ring 51. The separation cylinder 5 is rotatably connected with 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 transmission 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 outside the sleeve 2. The rotation center lines of the driving ring 32 and the separation cylinder 5 coincide. A first magnet 34 is arranged on the inside of the driving ring 32, and a second magnet 35 is arranged outside the separation cylinder 5. The first magnet 34 and the second magnet 35 have opposite magnetic properties 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, under the action of magnetic force, when the drive ring 32 rotates around the sleeve 2, the internal separation cylinder 5 will be driven to rotate, thereby driving the separation cylinder 5. For example, the sleeve 2 in the present application is made of aluminum alloy to reduce its influence on the interaction between the magnets. Therefore, when in use, only the external drive ring 32 needs to be driven.

[0026] Exemplarily, the driving assembly 3 further includes a bevel gear 33 rotatably mounted on the housing 31, and the outer edge of the driving ring 32 is provided with a snap-in tooth meshing with the bevel gear 33, and the bevel gear 33 drives the driving ring 32 to rotate. The snap-in teeth on the bevel gear 33 and the driving ring 32 mesh with each other, and when driving is required, it is only necessary to drive the bevel gear 33. In some embodiments, the central axis of the bevel gear 33 is connected to a driving element such as a driving motor, so as to drive the bevel gear 33 to achieve driving of the separation cylinder 5.

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

[0028] The structure of the collector 4 is introduced as follows: 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 arranged in the collector 4, and the opening is communicated with the accommodating chamber 41. An outlet 42 is arranged 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 arranged 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, so as to realize the movable connection between the movable plate 44 and the bottom of the collector 4. An elastic member connected to the movable plate 44 is arranged 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] After the separation cylinder 5 is working, the gas-water separation is achieved by the action of centrifugal force, and the residual liquid water and other impurities are sent to the collector 4 through the drain port 54. The accommodating chamber 41 in the collector 4 is used to accommodate water and other impurities. The movable plate 44 movably arranged at the bottom of the collector 4 can be used for drainage of the collector 4. When the movable plate 44 is closed, the bottom of the collector 4 is closed, and when the movable plate 44 is opened, the bottom of the collector 4 is opened. Among them, the spring 45 in the movable groove 43 at the bottom of the movable plate 44 can be used to reset the movable plate 44 after it moves.

[0030] The collector 4 is also provided with a control groove 46, in which a turntable 6 is rotatably mounted, an arc groove 65 is provided on the turntable 6, a block 63 is provided in the arc groove 65, a movable rod 64 is hingedly connected to the block 63, and the end of the movable plate 44 is connected to the movable rod 64. A guide rod 61 is provided on the turntable 6, a guide groove 62 is provided on the guide rod 61, the guide rod 61 passes through the turntable 6, a guide block matching the guide groove 62 is provided on the turntable 6, and the bottom of the guide rod 61 extends to the outside of the collector 4. The guide groove 62 is bent, and the bending direction of the guide groove 62 is along the length direction of the guide rod 61 and bends toward the circumference of the guide rod 61.

[0031] A turntable 6 is rotatably mounted in the control groove 46. An arc groove 65 provided on the turntable 6 is connected to a movable rod 64 through a block 63. The movable rod 64 is connected to the movable plate 44. When the turntable 6 rotates, the movable rod 64 is driven through the arc groove 65 and the block 63. In addition, the guide rod 61 and the turntable 6 cooperate with each other. A curved guide groove 62 is provided on the guide rod 61. The guide block on the turntable 6 and the guide groove 62 are adapted to each other. When the guide rod 61 moves, it acts on the turntable 6 through the guide groove 62, converting the linear motion of the guide rod 61 into the circumferential rotation of the turntable 6, thereby driving the turntable 6. When the turntable 6 rotates, it drives the movable rod 64 to move, so as to drive the movable plate 44. Therefore, when it is necessary to open the bottom of the collection chamber for drainage, the turntable 6, the movable rod 64 and the movable plate 44 can be driven by pressing the guide rod 61, so as to open the movable plate 44 and realize the opening of 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 the present application, by setting the structure of the sleeve 2 and the separation component, when the gas in the gas transmission 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 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 convenient for control, and after the collector 4 completes a period of collection, it is convenient to drain the water from the collector 4.

[0033] The following is an introduction to the working principle of this application: During the gas production process, liquid water and other impurities in the gas transmission pipe 1 will be 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 driving 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 drainage port 54 by the action of centrifugal force, and the accommodating chamber 41 in the collector 4 can store the liquid water and other impurities.

[0034] When the collector 4 contains enough impurities such as water, 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. The turntable 6 is driven by the guide rod 61 and the guide groove 62. During the rotation of the turntable 6, the arc groove 65 acts on the movable rod 64, so that the movable rod 64 and the movable plate 44 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.
