The air inlet end at the top of the circular blind cylinder is connected to the air outlet end at the bottom of the condenser. A spiral sheet is installed in the middle of the circular blind cylinder. A leakage hole is opened at the bottom of the outer circular surface of the circular blind cylinder. A gas transmission channel is installed on the side of the bottom of the liquid storage tank. Natural gas is discharged into the condenser through the air outlet end of the exhaust device. The natural gas can begin to cool down and present a low-temperature state, so that the hydrocarbon components in the natural gas will undergo a phase change and condense into liquid. As the natural gas enters the circular blind cylinder, the liquid hydrocarbon components leak down from the leakage hole, thereby realizing separation from the gaseous natural gas, and then dehydrogenation treatment can be carried out.
[0005] Preferably, the funnel has a diameter that gradually decreases from top to bottom, and the rotating shaft passes through the center of the storage bin and the center of the funnel, and is installed near the funnel using impeller blades. As the impeller blades rotate rapidly, the funnel can guide the gas, and combined with the funnel having a diameter that gradually decreases from top to bottom to form an inverted cone, the flow rate of the gas can be increased, allowing the natural gas to flow smoothly.
[0006] Preferably, the impeller blades are installed at an angle, and are evenly installed on the outer circumferential surface of the rotating shaft and close to the funnel.
[0007] Preferably, the auxiliary component includes a support rod, the bottom end of the support rod is fixedly installed with the top end of the rotating shaft by a screw, the top end of the support rod is fixedly installed with a connecting ball, the spherical surface outside the connecting ball is fixedly installed with a round rod, the top of the outer spherical surface of the round rod is fixedly installed with a brush, and the bottom end of the round rod is fixedly installed with a magnetic ball, the rotating shaft is driven to rotate by the output end of the servo motor, and the round rod is driven to rotate together under the support connection of the support rod and the connecting ball, so that the brush can be driven to rotate in a circle, and the top end of the brush is used to fit the conical surface inside the conical filter screen, so that the top end of the brush brushes the conical surface inside the conical filter screen, thereby reducing the adhesion of dust and impurities on the conical filter screen, and the interaction between the structures is used to connect the structures together.
[0008] Preferably, the round rods are installed at an angle, there are three round rods, and the three round rods are evenly installed on the spherical surface outside the connecting ball, and the brushes are evenly installed on the top of the outer circumferential surface of the round rods.
[0009] Preferably, the opening and closing module includes a rotating disk and a fixed disk, the center of the rotating disk is fixedly installed between the outer cylindrical surface of the rotating shaft, the rotating disk is installed at a position close to the bottom of the inner cavity of the storage bin, the center of the fixed disk is provided with a through hole, the rotating shaft passes through the through hole position at the center of the fixed disk, the edge of the outer side of the fixed disk is fixedly installed between the inner side surface of the storage bin, the bottom of the fixed disk is in contact with the top of the rotating disk, and a straight-line hole is provided on the side of the outer side of the fixed disk, and an elliptical hole is provided on the side of the outer side of the rotating disk. When the rotating shaft rotates, the rotating disk can be driven to rotate, while the fixed disk always remains in a stationary state. When the position of the elliptical hole is staggered with the position of the straight-line hole, the rotating disk can block the straight-line hole, thereby slowing down the flow speed of natural gas in the storage bin and increasing the contact time between the natural gas and the dry water-absorbing material. As the rotating disk continues to rotate, the position of the elliptical hole overlaps with the position of the straight-line hole, so that the natural gas can circulate again, further promoting the removal of water vapor in the natural gas.
[0010] Preferably, the straight-line holes are evenly arranged at the sides of the outer side of the fixed disk, and the elliptical holes are evenly arranged at the sides of the outer side of the rotating disk, and the positions of the straight-line holes correspond to the positions of the elliptical holes.
[0011] Preferably, the liquid storage tank is installed directly below the condenser, the opening of the circular blind cylinder faces the top of the gas transmission channel, and the bottom of the gas transmission channel extends to the bottom position of the inner cavity of the dehydrogenation tower. When the natural gas enters the circular blind cylinder, under the guidance of the spiral blades, the natural gas presents a vortex state, and the liquid hydrocarbon components are heavier and are subjected to greater centrifugal force, so they move along the inner wall of the circular blind cylinder, further promoting the leakage of the liquid hydrocarbon components from the leakage hole.
[0012] An appropriate amount of hydrocarbon adsorbent is placed at the bottom of the dehydrogenation tower cavity, and the bottom end of the gas transmission channel extends to the bottom of the dehydrogenation tower cavity. The surface of the hydrocarbon adsorbent has many tiny pores, which can make the natural gas fully contact with the adsorbent, so as to adsorb the residual hydrocarbons in the natural gas, thereby performing integrated dehydration and dehydrogenation treatment of the natural gas.
[0013] Preferably, a pretreatment component is installed inside the dehydration tower and near the air inlet, and the pretreatment component includes an annular ring, which is fixedly installed to the inner wall of the dehydration tower and near the top by bolts, a conical filter is fixedly installed in the middle of the inner side of the annular ring, a pointed base is fixedly installed in the middle of the top of the conical filter, a swing rod is fixedly installed on the outer side of the pointed base and near the conical surface of the outer side of the conical filter, a square magnetic block is fixedly installed on the bottom end of the swing rod, and a striking block is fixedly installed on the outer circular surface of the swing rod and near the conical filter. As the natural gas enters the interior of the dehydration tower from the air inlet, the natural gas contacts the conical filter, and the impurities carried by the natural gas can be filtered through the conical filter, so that the natural gas can be pretreated to reduce the impact of the impurities, and because the conical filter is conical, the filtered impurities can roll, so that the impurities can roll to the inner side of the annular ring.
[0014] Preferably, there are two swing rods, and the two swing rods are symmetrically installed along the tip base. The material of the striking block is rubber. When the support rod rotates, the magnetic ball can be driven to rotate. The magnetic ball and the square magnetic block are combined with the same magnetic poles, so that repulsive magnetic force will be generated when the two meet. The square magnetic block is subjected to the reverse magnetic thrust of the magnetic ball, so that the swing rod drives the striking block to rotate and adjust the angle away from the conical filter. As the magnetic ball continues to rotate, the reverse magnetic thrust disappears when the magnetic ball moves away from the square magnetic block. The swing rod drives the striking block to rotate in the opposite direction by utilizing the gravity of the swing rod and the square magnetic block itself, and strikes the conical filter, causing the conical filter to vibrate, so that the debris remaining on the conical filter can fall off. The interaction between the structures is fully utilized, and combined with the magnetic force, the structures are connected together.
[0015] The present invention provides a gas dehydration and dehydrocarbonization device for natural gas production, which has the following beneficial effects: The gas dehydration and dehydrocarbonization device for natural gas production utilizes the output end of the servo motor to rotate, which can drive the rotating shaft to rotate, so that the impeller blades are driven to rotate together. The rotation of the impeller blades can blow the air in the storage bin downward, so that the natural gas entering the dehydration tower from the air inlet is sucked, thereby allowing the natural gas to enter the interior of the storage bin, so that the natural gas is fully in contact with the dry water-absorbing material in the storage bin, so that the water vapor in the natural gas can be adsorbed and the dehydration treatment can be carried out.
[0016] The gas dehydration and dehydrocarbonization device for natural gas production, as the natural gas enters the interior of the dehydration tower from the gas inlet, makes the natural gas contact with the conical filter, and can filter the impurities carried by the natural gas through the conical filter, so that the natural gas can be pre-treated to reduce the impact of the impurities, and because the conical filter is conical, the filtered impurities can be rolled, so that the impurities can roll to the inner position of the annular ring.
[0017] The gas dehydration and dehydrocarbonization device for natural gas production drives the rotating shaft to rotate through the output end of the servo motor, and under the support connection of the support rod and the connecting ball, the round rod is driven to rotate together, and the brush can be driven to rotate in a circle. The top end of the brush is fitted with the conical surface inside the conical filter, so that the top end of the brush brushes the conical surface inside the conical filter, thereby reducing the dust and impurities adhering to the conical filter.
[0018] The gas dehydration and dehydrocarbonization device for natural gas production generates a repulsive magnetic force when a magnetic ball meets a square magnetic block, and utilizes the reverse magnetic thrust of the magnetic ball on the square magnetic block to make a swing rod drive a striking block to rotate in a direction away from the conical filter to adjust the angle. As the magnetic ball continues to rotate, the reverse magnetic thrust disappears when the magnetic ball moves away from the square magnetic block. The swing rod and the gravity of the square magnetic block are utilized to drive the striking block to rotate in the reverse direction to strike the conical filter, causing the conical filter to vibrate, thereby causing debris remaining on the conical filter to fall off.
[0019] 5. The gas dehydration and dehydrocarbonization device for natural gas production uses impeller blades installed near the funnel. As the impeller blades rotate rapidly, the funnel can guide the gas. Combined with the gradual reduction of the funnel diameter from top to bottom to form an inverted cone, the flow rate of the gas can be increased, allowing the natural gas to flow smoothly.
[0020] 6. In the gas dehydration and dehydrocarbonization device for natural gas production, when the rotating shaft rotates, it can drive the rotating disk to rotate, while the fixed disk always remains stationary. When the position of the elliptical hole is staggered with the position of the straight hole, the rotating disk can block the straight hole, thereby slowing down the flow speed of natural gas in the storage bin and increasing the contact time between natural gas and dry water-absorbing materials.
[0021] 7. The gas dehydration and dehydrogenation device for natural gas production uses the gas outlet end of the exhaust device to discharge natural gas into the condenser, so that the natural gas begins to cool down and presents a low-temperature state, causing the hydrocarbon components in the natural gas to undergo a phase change and condense into liquid. As the natural gas enters the circular blind tube, the liquid hydrocarbon components leak out from the leakage hole, thereby achieving separation from the gaseous natural gas, and then dehydrogenation treatment can be carried out.
[0022] 8. In the gas dehydration and dehydrogenation device for natural gas production, when the natural gas enters the circular blind tube, it is guided by the spiral blades to present a swirling state, forming liquid hydrocarbon components which are heavier and are subjected to greater centrifugal force, so they move along the inner wall of the circular blind tube, further promoting the leakage of the liquid hydrocarbon components from the leakage holes.
[0023] 9. The gas dehydration and dehydrogenation device for natural gas production utilizes a proper amount of hydrocarbon adsorbent at the bottom of the dehydrogenation tower cavity, and the bottom end of the gas transmission channel extends to the bottom of the dehydrogenation tower cavity. The surface of the hydrocarbon adsorbent has many tiny pores, which can make the natural gas fully contact with the adsorbent, so as to adsorb the residual hydrocarbons in the natural gas, thereby performing integrated dehydration and dehydrogenation treatment of the natural gas.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: A gas dehydration and dehydrogenation device for natural gas production, comprising a dehydration tower 1 and a dehydrogenation tower 2, wherein an air inlet 3 is installed on the outer circumferential surface of the dehydration tower 1 near the top, a servo motor 4 is installed in the middle of the bottom of the dehydration tower 1, and a dryer 5 is installed in the middle of the outer side of the dehydrogenation tower 2; A primary processing mechanism 6, which is used to process water vapor in the natural gas, and is installed in the middle of the dehydration tower 1; Among them, the primary processing mechanism 6 includes a storage bin 61 and a funnel 62. The storage bin 61 is installed at the bottom of the inner cavity of the dehydration tower 1, and the funnel 62 is fixedly installed in the middle of the top of the storage bin 61. A rotating shaft 63 is rotatably installed in the middle of the inside of the storage bin 61. The bottom end of the rotating shaft 63 is fixedly installed between the output end of the servo motor 4 through a coupling. An exhaust device 64 is installed at the bottom of the storage bin 61 and close to the outer cylindrical surface of the dehydration tower 1. An auxiliary component 65 is installed at the top of the rotating shaft 63. An opening and closing module 66 is installed on the outer cylindrical surface of the rotating shaft 63 and close to the bottom of the inner cavity of the storage bin 61. The outer cylindrical surface of the rotating shaft 63 and close to the funnel 6 The impeller blade 67 is installed at the position of 2. The staff adds an appropriate amount of dry water-absorbing material into the storage bin 61, and turns on the servo motor 4 to work. The output end of the servo motor 4 is rotated to drive the rotating shaft 63 to rotate, so that the impeller blade 67 is driven to rotate together. The rotation of the impeller blade 67 can blow the air in the storage bin 61 downward, so that the natural gas entering the dehydration tower 1 from the air inlet 3 is sucked, so that the natural gas enters the interior of the storage bin 61, so that the natural gas is fully in contact with the dry water-absorbing material in the storage bin 61, so that the water vapor in the natural gas can be adsorbed, and the dehydration process can be performed; The diameter of the funnel 62 gradually decreases from top to bottom, and the rotating shaft 63 passes through the center of the storage bin 61 and the center of the funnel 62 .
[0028] By installing the impeller blade 67 near the funnel 62, the funnel 62 can guide the gas as the impeller blade 67 rotates rapidly. In addition, the funnel 62 gradually decreases in diameter from top to bottom to form an inverted cone, which can increase the flow rate of the gas and make the natural gas flow smoothly.
[0029] The impeller blades 67 are installed at an angle, and the impeller blades 67 are evenly installed on the outer circumferential surface of the rotating shaft 63 and close to the funnel 62 .
[0030] The opening and closing module 66 includes a rotating disk 661 and a fixed disk 662. The center of the rotating disk 661 is fixedly installed between the outer cylindrical surface of the rotating shaft 63. The rotating disk 661 is installed at a position close to the bottom of the inner cavity of the storage bin 61. A through hole is opened at the center of the fixed disk 662. The rotating shaft 63 passes through the through hole at the center of the fixed disk 662. The edge of the outer side of the fixed disk 662 is fixedly installed between the inner side of the storage bin 61. The bottom of the fixed disk 662 fits with the top of the rotating disk 661. A straight hole 663 is opened on the side of the outer side of the fixed disk 662. A through hole 663 is opened on the side of the outer side of the rotating disk 661. The elliptical hole 664 can drive the rotating disk 661 to rotate when the rotating shaft 63 rotates, while the fixed disk 662 always remains stationary. When the position of the elliptical hole 664 is staggered with the position of the straight hole 663, the rotating disk 661 can block the straight hole 663, thereby slowing down the flow speed of the natural gas in the storage bin 61 and increasing the contact time between the natural gas and the dry water-absorbing material. As the rotating disk 661 continues to rotate, the position of the elliptical hole 664 overlaps with the position of the straight hole 663, so that the natural gas can circulate again, further promoting the removal of water vapor in the natural gas.
[0031] The straight holes 663 are evenly arranged on the outer side of the fixed disk 662 , and the elliptical holes 664 are evenly arranged on the outer side of the rotating disk 661 . The positions of the straight holes 663 correspond to the positions of the elliptical holes 664 .
[0032] The second embodiment is based on the first embodiment. Figures 1 to 8 As shown: A secondary processing mechanism 7, which is used to process hydrocarbon substances in the natural gas, and is installed in the middle of the dehydrogenation tower 2; The secondary treatment mechanism 7 includes a condenser 71 and a liquid storage tank 72. The condenser 71 is installed inside the dehydrogenation tower 2 and near the top. The air inlet end of the condenser 71 is connected to the air outlet end of the exhaust device 64. The liquid storage tank 72 is installed at the bottom of the condenser 71. A circular blind cylinder 73 is fixedly installed in the middle of the liquid storage tank 72. The air inlet end at the top of the circular blind cylinder 73 is connected to the air outlet end at the bottom of the condenser 71. A spiral sheet 74 is installed in the middle of the circular blind cylinder 73. A leakage hole 75 is provided at the bottom of the circular surface, and a gas delivery channel 76 is installed at the side of the bottom of the liquid storage tank 72. When the condenser 71 is turned on for operation, natural gas is discharged into the condenser 71 through the gas outlet end of the exhaust device 64. The natural gas begins to cool down and presents a low-temperature state, so that the hydrocarbon components in the natural gas undergo a phase change and condense into liquid. As the natural gas enters the circular blind tube 73, the liquid hydrocarbon components leak out from the leakage hole 75, thereby achieving separation from the gaseous natural gas, and then dehydrocarbon treatment can be carried out.
[0033] When the natural gas enters the circular blind tube 73, under the guidance of the spiral blade 74, the natural gas presents a swirling state, and the liquid hydrocarbon component is heavier and is subjected to a large centrifugal force, so it moves along the inner wall of the circular blind tube 73, further promoting the liquid hydrocarbon component to leak out from the leakage hole 75.
[0034] The liquid storage tank 72 is installed directly below the condenser 71, and the opening of the circular blind cylinder 73 faces the top of the gas transmission channel 76. The bottom of the gas transmission channel 76 extends to the bottom position of the inner cavity of the dehydrogenation tower 2. An appropriate amount of hydrocarbon adsorbent is contained in the bottom of the inner cavity of the dehydrogenation tower 2, and the bottom end of the gas transmission channel 76 extends to the bottom position of the inner cavity of the dehydrogenation tower 2. The surface of the hydrocarbon adsorbent has many tiny pores, which can make the natural gas fully contact with the adsorbent, so as to adsorb the residual hydrocarbon substances in the natural gas, thereby performing integrated dehydration and dehydrogenation treatment on the natural gas.
[0035] The third embodiment is based on the first and second embodiments. Figures 1 to 9 As shown: A pretreatment assembly 8 is installed inside the dehydration tower 1 and near the air inlet 3. The pretreatment assembly 8 includes an annular ring 81, which is fixedly installed with the inner wall of the dehydration tower 1 and near the top through bolts. A conical filter 82 is fixedly installed in the middle of the inner side of the annular ring 81, and a tip base 83 is fixedly installed in the middle of the top of the conical filter 82. A swing rod 84 is fixedly installed on the outer side of the tip base 83 and near the conical surface of the outer side of the conical filter 82. The bottom end of the swing rod 84 is fixedly installed. There is a square magnetic block 85, and a striking block 86 is fixedly installed on the outer cylindrical surface of the swing rod 84 and near the conical filter 82. As the natural gas enters the dehydration tower 1 from the air inlet 3, the natural gas contacts the conical filter 82, and the conical filter 82 can filter the impurities carried by the natural gas, so the natural gas can be pre-treated to reduce the impact of the impurities. In addition, since the conical filter 82 is conical, the filtered impurities can roll, so that the impurities can roll to the inner side of the annular ring 81.
[0036] There are two swing rods 84 , and the two swing rods 84 are symmetrically installed along the tip base 83 , and the striking block 86 is made of rubber.
[0037] The auxiliary component 65 includes a support rod 651, the bottom end of which is fixedly mounted to the top of the rotating shaft 63 by means of screws, a connecting ball 652 is fixedly mounted to the top of the support rod 651, a round rod 653 is fixedly mounted on the spherical surface outside the connecting ball 652, a brush 654 is fixedly mounted on the top of the outer circumferential surface of the round rod 653, and a magnetic ball 655 is fixedly mounted on the bottom end of the round rod 653. The rotating shaft 63 is driven to rotate by the output end of the servo motor 4, and the round rod 653 is driven to rotate together under the support and connection of the support rod 651 and the connecting ball 652, so that the brush 654 can be driven to rotate in a circle, and the top end of the brush 654 is fitted with the conical surface inside the conical filter 82, so that the top end of the brush 654 brushes the conical surface inside the conical filter 82, thereby reducing the dust impurities adhering to the conical filter 82.
[0038] The round rod 653 is installed obliquely, and there are three round rods 653, and the three round rods 653 are evenly installed on the spherical surface outside the connecting ball 652, and the brush 654 is evenly installed on the top of the outer circumferential surface of the round rod 653. When the support rod 651 rotates, the magnetic ball 655 can be driven to rotate. In combination with the magnetic ball 655 and the square magnetic block 85 being the same magnetic poles, a repulsive magnetic force will be generated when the two meet. The square magnetic block 85 is subjected to the reverse magnetic thrust of the magnetic ball 655, so that the swing rod 84 drives the striking block 86 to rotate and adjust the angle in the direction away from the conical filter 82. As the magnetic ball 655 continues to rotate, the reverse magnetic thrust disappears when the magnetic ball 655 is away from the square magnetic block 85. The swing rod 84 drives the striking block 86 to rotate in the opposite direction by utilizing the gravity of the swing rod 84 and the square magnetic block 85, and strikes the conical filter 82, so that the conical filter 82 vibrates, and the debris remaining on the conical filter 82 can fall off.
[0039] When in use, the staff first adds an appropriate amount of dry water-absorbing material into the storage bin 61, then adds an appropriate amount of hydrocarbon adsorbent into the dehydrogenation tower 2, and transports the natural gas to be treated from the air inlet 3 to the dehydration tower 1; As the natural gas enters the dehydration tower 1 from the gas inlet 3, the natural gas contacts the conical filter 82, and the impurities carried by the natural gas can be filtered through the conical filter 82, so that the natural gas can be pre-treated to reduce the impact of the impurities. In addition, since the conical filter 82 is conical, the filtered impurities can roll, so that the impurities can roll down to the inner side of the annular ring 81. The servo motor 4 is turned on to work, and the output end of the servo motor 4 is rotated to drive the rotating shaft 63 to rotate. Under the support and connection of the support rod 651 and the connecting ball 652, the round rod 653 is driven to rotate together, and the brush 654 is driven to rotate in a circle. The top of the brush 654 is fitted with the conical surface inside the conical filter 82, so that the top of the brush 654 brushes the conical surface inside the conical filter 82, thereby reducing the dust impurities adhering to the conical filter 82; At the same time, when the support rod 651 rotates, the magnetic ball 655 can be driven to rotate. The magnetic ball 655 and the square magnetic block 85 are the same magnetic poles, so that when the two meet, a repulsive magnetic force will be generated. The square magnetic block 85 is subjected to the reverse magnetic thrust of the magnetic ball 655, so that the swing rod 84 drives the striking block 86 to rotate and adjust the angle in the direction away from the conical filter 82. As the magnetic ball 655 continues to rotate, the reverse magnetic thrust disappears when the magnetic ball 655 is away from the square magnetic block 85. The swing rod 84 drives the striking block 86 to rotate in the opposite direction by utilizing the gravity of the swing rod 84 and the square magnetic block 85, and strikes the conical filter 82, so that the conical filter 82 vibrates, and the debris remaining on the conical filter 82 can fall off. As the rotating shaft 63 rotates, the impeller blade 67 is driven to rotate together. The rotation of the impeller blade 67 can blow the air in the storage bin 61 downward, so that the natural gas entering the dehydration tower 1 from the air inlet 3 is sucked, so that the natural gas enters the interior of the storage bin 61, so that the natural gas is fully in contact with the dry water-absorbing material in the storage bin 61, so that the water vapor in the natural gas can be adsorbed, and the dehydration process can be performed; When the rotating shaft 63 rotates, the rotating disk 661 can be driven to rotate, while the fixed disk 662 always remains stationary. When the position of the elliptical hole 664 is staggered with the position of the straight hole 663, the rotating disk 661 can block the straight hole 663, thereby slowing down the flow speed of the natural gas in the storage bin 61 and increasing the contact time between the natural gas and the dry water-absorbing material. As the rotating disk 661 continues to rotate, the position of the elliptical hole 664 overlaps with the position of the straight hole 663, so that the natural gas can circulate again, further promoting the removal of water vapor in the natural gas. At this time, the natural gas with water vapor removed enters the exhaust device 64, and the condenser 71 is turned on to work. The natural gas is discharged into the condenser 71 through the gas outlet of the exhaust device 64, and the natural gas begins to cool down and presents a low-temperature state, so that the hydrocarbon components in the natural gas undergo a phase change and condense into liquid. As the natural gas enters the circular blind tube 73, the liquid hydrocarbon components leak down from the leakage hole 75, thereby achieving separation from the gaseous natural gas, and then dehydrogenation treatment can be performed; When the natural gas enters the circular blind tube 73, under the guidance of the spiral blade 74, the natural gas presents a swirling state, and the liquid hydrocarbon components are heavier and are subjected to a large centrifugal force, so they move along the inner wall of the circular blind tube 73, further promoting the liquid hydrocarbon components to leak out from the leakage hole 75; Moreover, a proper amount of hydrocarbon adsorbent is contained at the bottom of the inner cavity of the dehydrogenation tower 2, and the bottom end of the gas transmission channel 76 extends to the bottom position of the inner cavity of the dehydrogenation tower 2. The surface of the hydrocarbon adsorbent has many tiny pores, so that the natural gas can be fully contacted with the adsorbent, so that the residual hydrocarbons in the natural gas are adsorbed, thereby performing an integrated dehydration and dehydrogenation treatment on the natural gas; The natural gas that has been processed finally passes through the dryer 5 to be dried again and then output.
