Description

Technical Field

[0001] The present invention relates to the technical field of natural gas processing, and in particular to a natural gas triethylene glycol dehydration device and a use method thereof. Background Art

[0002] The natural gas triethylene glycol dehydration process is one of the most commonly used methods in the natural gas industry. It belongs to the solvent absorption method. This process uses glycol substances as absorbents to fully contact with natural gas, so that water is transferred to the solvent to achieve the purpose of dehydration. Triethylene glycol has strong hydrophilicity and non-conductive properties. It can form hydrogen bonds with water in natural gas, thereby achieving efficient dehydration. The core equipment of this process is the absorption tower, in which the natural gas dehydration process is completed in the absorption tower, and the triethylene glycol rich liquid is heated in the regeneration tower to separate the water under low pressure and high temperature, completing the regeneration process and realizing recycling.

[0003] The existing Chinese patent publication number CN117643744A discloses that the speed of gas generation by triethylene glycol rich liquid is accelerated by heating and stirring to achieve the effect of removing carbon dioxide gas. However, when the triethylene glycol rich liquid reacts, the heating temperature is constant, which only leads to limited separation of carbon dioxide and fails to completely treat the internal gas, making it difficult to achieve a rapid and thorough removal effect, thereby reducing the efficiency of repeated use of water absorption.

[0004] Secondly, the triethylene glycol rich liquid is a viscous liquid. When the temperature is continuously increased, it will produce carbon dioxide and sulfides. In addition, the characteristics of the viscous liquid will cause the triethylene glycol rich liquid and sulfides to adhere to the inner wall of the tower body, slowing down the flow rate and easily causing corrosion in the tower. At the same time, the incompletely purified triethylene glycol rich liquid cannot be reprocessed, which greatly reduces the subsequent use of triethylene glycol, affects the service life of the device, and reduces the transportation of pipelines. Therefore, the present application provides a natural gas triethylene glycol dehydration device and a method for using the same to meet the needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a natural gas triethylene glycol dehydration device and a method for using the same, so as to solve the problem that during the existing triethylene glycol rich liquid reaction, the heating temperature is constant, which only leads to limited separation of carbon dioxide, and the internal gas cannot be completely processed, making it difficult to achieve a rapid and thorough removal effect, thereby reducing the efficiency of repeated use of water absorption. Secondly, the triethylene glycol rich liquid is a viscous liquid, which will produce carbon dioxide and sulfide when continuously heated, and the characteristics of the viscous liquid will make the triethylene glycol rich liquid and sulfide adhere to the inner wall of the tower body, slowing down the flow rate and easily causing corrosion in the tower. At the same time, the incompletely purified triethylene glycol rich liquid cannot be reprocessed, resulting in a significant reduction in the subsequent use of the triethylene glycol, affecting the service life of the device, and reducing the problem of pipeline transportation.

[0016] The present application also provides another technical solution: a method for using a natural gas triethylene glycol dehydration device, comprising the following steps:

[0017] S1: Connect the liquid discharge port of the absorption tower to the delivery pipe on the top of the tower body, so that the triethylene glycol rich liquid from the absorption tower is injected into the interior of the tower body;

[0018] S2: The triethylene glycol rich liquid injected into the tower body flows into the two channels through the guide pipe for filtration, and then is discharged to the drum through the guide pipe;

[0019] S3: When TEG is discharged into the drum, the box motor rotates to drive the drum to rotate. At the same time, the heating ring continuously heats the TEG rich liquid inside the drum, increasing the TEG rich liquid on the heating surface and quickly generating gas and sulfide.

[0020] S4: The scraper inside the drum scrapes off the TEG rich liquid and derivatives on the inner wall of the drum to prevent residue. The two layers of drums with different temperatures accelerate the speed at which TEG rich liquid produces gas and sulfide inside. The gas is discharged from the tower through the gas pipe and the fan pipe.

[0021] S5: After the reaction in the drum, the TEG rich liquid carries the reacted derivatives and sulfides and flows to the liquid collecting bin for collection. When the pressing plate contacts the trigger block, the liquid infusion is stopped, and the output end of the oil cylinder squeezes the pressing plate to make the TEG rich liquid pass through the molecular sieve, separating the internal sulfides and water from the TEG rich liquid.

[0022] S6: When the conical tube inputs the re-separated triethylene glycol rich liquid into the electrode diversion assembly, the triethylene glycol rich liquid flows in through the top of the tee. When the triethylene glycol rich liquid contains water, the carbon dioxide gas and sulfide are not completely separated. The conductive rod drives the connecting rod to move, and drives the baffle to descend to the inside of the tee to block the discharge port. At this time, the triethylene glycol rich liquid that has not been purified and separated completely will be transported to the delivery pipe through the reflux pipe for reprocessing, and the triethylene glycol rich liquid that has not been purified and separated completely will be continuously purified.

[0023] Compared with the prior art, the present invention has at least the following beneficial effects:

[0024] In the above scheme, by setting up a filtering and separation component, utilizing the cooperation between the guide pipe, filter, drum, heating ring, air pipe, scraper, vibration plate and elastic frame, the triethylene glycol rich liquid is filtered through a layer and then flows into the drum. The internal triethylene glycol rich liquid is heated by the heating ring to produce carbon dioxide and sulfide. The air pipe transports the carbon dioxide gas. The sulfide follows the triethylene glycol rich liquid and flows into the next layer of the drum for heating treatment at different temperatures, so that it can be removed more efficiently. At the same time, the scraper scrapes the liquid on the inner wall of the drum, and removes the liquid through the vibration plate to prevent the residue and accumulation of liquid and sulfide, which will corrode the inner wall of the drum.

[0025] By setting up impurity removal and discharge components, using a liquid infusion pipe valve, a trigger rod, a liquid collecting bin, a cylinder, a trigger block pressure plate and a molecular sieve, when the triethylene glycol rich liquid removes the internal gas by heating, the triethylene glycol rich liquid carries the sulfide flow into the liquid collecting bin for accumulation. When the accumulation height continues to rise and pushes the pressure plate to touch the trigger block, the liquid infusion pipe valve is closed to stop the infusion, the output end of the cylinder is squeezed toward the pressure plate, and the triethylene glycol rich liquid flows into the conical tube through the molecular sieve. The molecular sieve simultaneously separates the sulfide and water substances in the triethylene glycol rich liquid, thereby improving the purity of the triethylene glycol rich liquid, reducing the energy consumption of the triethylene glycol rich liquid, improving the durability of the circulating use of the triethylene glycol rich liquid, reducing the cost of using the device, and improving the filtering effect of the molecular sieve.

[0026] At the same time, in conjunction with the electrode shunt assembly, using a three-way pipe, a conductive paddle, a conductive rod, a connecting rod, a main gear, a rack, a baffle, a bayonet slot, a discharge port and a reflux pipe, after the triethylene glycol rich liquid is separated from the sulfide and the gas, it flows into the three-way pipe through the tapered pipe and contacts the conductive paddle. At this time, the paddle is not charged to detect the inside of the triethylene glycol rich liquid. When the triethylene glycol rich liquid contains impurities and water components, the conductive paddle conducts electricity and generates attraction with the conductive rod. The two are connected in series, and the conductive rod moves to drive the main gear to rotate, thereby controlling the baffle at the reflux pipe. The baffle plate of the discharge port is closed, and the triethylene glycol rich liquid containing impurities and water passes through the reflux pipe for reprocessing. The triethylene glycol rich liquid that has not been completely purified and separated will be transported to the delivery pipe through the reflux pipe for reprocessing. The triethylene glycol rich liquid that has not been completely purified and separated is continuously purified. When the triethylene glycol rich liquid does not contain impurities and water, the discharge port is continuously opened to transport the triethylene glycol to the front end for recycling in natural gas dehydration, thereby improving the use effect of triethylene glycol, extending the service life of the device, increasing the transportation capacity of the pipeline, and improving the efficiency of dehydration.

[0048] like Figures 1 to 13 As shown, an embodiment of the present invention provides a natural gas triethylene glycol dehydration device, including a tower body 1, an artificial ladder platform 2 is installed on the outer surface of the tower body 1, a box motor 3 is installed at one end of the tower body 1, a servo motor 4 is installed on the top of the tower body 1, a fan blade tube 10 is installed at the output end of the servo motor 4, a delivery pipe 5 is installed at one end of the top of the tower body 1, and an exhaust pipe 9 is installed at the other end of the top of the tower body 1; it also includes a filtering and separating component 6, a filtering and separating component 6 is installed at the bottom of the delivery pipe 5, and the filtering and separating component 6 is used to filter impurities and sulfides contained in triethylene glycol; an impurity removal and emission component 7, a impurity removal and emission component 7 is installed at the bottom of the filtering and separation component 6, and the impurity removal and emission component 7 is used to collect triethylene glycol and remove internal sulfides and carbon dioxide again; an electrode shunt component 8, an electrode shunt component 8 is installed at the bottom of the impurity removal and emission component 7, and the electrode shunt component 8 is used for a repeated process of discharging or refluxing triethylene glycol.

[0049] As an implementation method in this embodiment, Figures 5 to 8As shown, a pressure relief valve is installed on the top of the tower body 1, the output end of the box motor 3 is an arc-shaped gear, the output end of the servo motor 4 is provided with a pipeline, a plurality of fan blades are arranged inside the pipeline, the delivery pipe 5 is a three-way through pipe, and the filtering and separating component 6 includes a guide pipe 61, which is installed at the bottom of the delivery pipe 5, a filter 62 is installed at one end of the guide pipe 61, a sleeve pipe 63 is installed at one end of the guide pipe 61, a hole is opened inside the sleeve pipe 63, a roller 64 is rotatably connected inside the sleeve pipe 63, the inner wall of the roller 64 and the inner wall of the hole are fitted together, the installation angle of the roller 64 is set to be inclined at 15 degrees, a heating ring 65 is installed on the surface of the roller 64, a fixed shaft seat 66 is installed at one end of the roller 64, and the top of one end of the fixed shaft seat 66 An air delivery pipe 67 is installed, an extension seat 613 is installed at one end of the fixed rotating shaft seat 66, a scraper 68 is installed at one end of the extension seat 613, a vibration plate 69 is hinged at the bottom of the scraper 68, a connecting block 610 is installed at one end of the vibration plate 69, a support plate 611 is rotatably connected to the bottom of the connecting block 610, a positioning rod 612 is installed at one end of the support plate 611, an elastic frame 614 is installed at the bottom of one end of the support plate 611, a rotating lever 615 is installed on the inner wall of the drum 64, and the position of the rotating lever 615 is set on the rotation path of the support plate 611. When the triethylene glycol rich liquid enters the tower body 1 through the delivery pipe 5, the guide pipe 61 first guides the triethylene glycol rich liquid to the filter 62, and after a layer of filtration, it flows to the next through the bottom guide pipe 61. At the filter 62, the triethylene glycol rich liquid after double-layer filtration flows to the collar pipe 63 through the guide pipe 61, and the box motor 3 is started. The arc gear at the output end of the box motor 3 meshes with the gear at one end of the roller 64 inclined at 15 degrees and rotates synchronously. The collar pipe 63 is arranged at the bottom of the filter 62 and does not rotate. Since the collar pipe 63 and the roller 64 are rotatably installed through a sealed bearing and are partially inside the roller 64, when one end of the roller 64 rotates, the triethylene glycol rich liquid flows into the inside of the roller 64 through the collar pipe 63. At this time, the heating ring 65 continues to heat up before, and continuously heats the triethylene glycol rich liquid inside the roller 64. During the rolling process of the roller 64, the triethylene glycol rich liquid is driven to roll inside, thereby increasing the heating surface. Rapid temperature rise generates gas and sulfide. The air pipe 67 on the fixed rotating shaft seat 66 at one end of the drum 64 is affected by the rotation of the fan blades inside the fan blade tube 10, generating negative pressure to quickly absorb the gas generated inside the drum 64 from the inside of the drum 64 to the air pipe 67, and transport it to the exhaust pipe 9 for gas treatment. When the drum 64 rotates, the scraper 68 scrapes off the triethylene glycol rich liquid and sulfide residues on the inner wall of the drum 64 to prevent them from remaining on the inner wall of the drum 64. The extension seat 613 at one end is fixed to one end of the fixed rotating shaft seat 66, and is fixed by the spring of the extension seat 613 itself and the rotation seat to continuously support the inner wall of the drum 64. At the same time, the rotating lever 615 rotates with the inner wall of the drum 64, and collides with the support plate 611 at the bottom every time it rotates one circle.The support plate 611 is fanned at the front end of the positioning rod 612, and the elastic frames 614 installed at the upper and lower ends of the support plate 611 enable the support plate 611 to perform short-term reciprocating fanning to provide short-term movement. The fanning of the support plate 611 causes the rotationally connected connecting block 610 to move. When the connecting block 610 moves, the vibration plate 69 at one end is fanned, and the force generated by the fanning is transmitted to the scraper 68, thereby preventing the liquid from remaining on the surface and accelerating the flow of the liquid.

[0050] As an implementation method in this embodiment, Figures 8 to 11 As shown, the impurity removal and discharge component 7 includes a liquid infusion pipe valve 71, which is installed at one end of the guide pipe 61, and a liquid collecting bin 74 is installed at one end of the liquid infusion pipe valve 71. A trigger rod 72 is arranged on the top of the liquid infusion pipe valve 71, and a feedback button 73 is arranged on the top of the trigger rod 72. A trigger block 77 is arranged on one end of the feedback button 73. An exhaust disk 75 is installed on the top of the liquid collecting bin 74, and an oil cylinder 76 is installed on the bottom of the exhaust disk 75. A conical tube 712 is installed on the bottom of the liquid collecting bin 74, and a molecular sieve 711 is installed on the top of the conical tube 712. A spring seat 710 is installed on the inner wall of the liquid collecting bin 74, and the spring seat 710 is arranged on the top of the molecular sieve 711. A pressure plate 79 is installed on the top of the spring seat 710, and a magnet 78 is arranged inside the pressure plate 79. The magnet 78 is arranged below the trigger block 77. When the triethylene glycol rich liquid flows to the The infusion pipe valve 71 flows into the interior of the liquid collecting bin 74 at one end through the infusion pipe valve 71. At this time, the triethylene glycol rich liquid accumulates in the liquid collecting bin 74, and lifts up the pressure plate 79. When the pressure plate 79 moves upward, the magnet 78 produces a certain amount of lifting effect on the pressure plate 79. When the pressure plate 79 contacts the trigger block 77, the feedback button 73 presses downward and contacts the trigger rod 72. The trigger rod 72 locks the inside of the infusion pipe valve 71 to close the infusion. The exhaust plate 75 transports the produced carbon dioxide gas and rises to the top of the tower body 1. At this time, the oil cylinder 76 outputs to squeeze the pressure plate 79 downward. When the pressure plate 79 is squeezed downward, the pressure plate 79 squeezes the spring seat 710 downward, and the triethylene glycol rich liquid is separated again through the molecular sieve 711. The triethylene glycol rich liquid after diversion flows into the next component through the tapered tube 712 for diversion treatment.

[0051] As an implementation method in this embodiment, Figures 11 to 13As shown, the electrode shunt assembly 8 includes a three-way pipe 81, which is installed at the bottom of the tapered tube 712, and a conductive paddle 82 is installed at one end of the three-way pipe 81. The conductive paddle 82 extends to the inside of the three-way pipe 81, and an insulating bin 83 is installed at one end of the conductive paddle 82. A conductive rod 84 is installed inside the insulating bin 83, and a spring is provided on the top of the conductive rod 84 to connect with the bottom of the conductive paddle 82. A power box 85 is installed at one end of the insulating bin 83, and a connecting rod 86 is rotatably connected to the bottom of the conductive paddle 82. One end of the connecting rod 86 is rotatably connected to a main gear 87, and one end of the main gear 87 is meshed and connected to a slave gear 88. A limiting frame 81 is installed at one end of the main gear 87 5. Both ends of the limit frame 815 are installed at one end of the slave gear 88. One end of the slave gear 88 is meshed with a rack 89. One end of the rack 89 is installed with a baffle 810. The size of the baffle 810 is the same as the inner diameter of the tee 81. The inside of the tee 81 is installed with a bayonet slot 811. One end of the bayonet slot 811 is installed with an extension frame 814. The top of the extension frame 814 is connected to the bottom of the baffle 810. One end of the tee 81 is provided with a discharge port 812. The other end of the tee 81 is provided with a reflux pipe 813. The other end of the reflux pipe 813 is provided at one end of the delivery pipe 5. When the conical pipe 712 inputs the triethylene glycol rich solution separated again into the electrode shunt assembly At 8, the triethylene glycol rich liquid flows in through the top of the three-way pipe 81, covering the conductive pick 82. At this time, the conductive pick 82 is not charged. Affected by the continuous power transmission of the power box 85 on one side of the insulating chamber 83, the conductive rod 84 is charged, and the triethylene glycol liquid itself is not conductive. When the conductive rod 84 is connected to the conductive pick 82, it means that when the triethylene glycol rich liquid is conductive, the triethylene glycol rich liquid contains water at this time, and the carbon dioxide gas and the sulfide are not completely separated. The conductive rod 84 drives the connecting rod 86 to move. When the connecting rod 86 moves, it drives the main gear 87 to rotate. When the main gear 87 rotates, the slave gear 88 at one end of the reflux pipe 813 rotates. When the slave gear 88 rotates, the one end The meshingly connected rack 89 moves upward and rises. When the rack 89 rises, the baffle 810 at one end rises inside the bayonet slot 811. When the baffle 810 rises, it drives the extension frame 814 to move with it, ensuring the airtightness of one side of the bayonet slot 811. Due to the action of the limiting frame 815, when the main gear 87 rotates, the slave gear 88 of the discharge port 812 at the other end rotates to drive the rack 89 to descend. At the same time, the baffle 810 descends to the inside of the three-way pipe 81 to block the discharge port 812. At this time, the triethylene glycol rich liquid that has not been completely purified and separated will be transported to the delivery pipe 5 through the reflux pipe 813 for further processing, and the triethylene glycol rich liquid that has not been completely purified and separated will be continuously purified.

[0052] The working principle of the technical solution provided by the present invention is as follows:

[0053] First, the drainage pipe of the absorption tower is connected to the delivery pipe 5 on the top of the tower body 1 through the artificial ladder platform 2, so that the triethylene glycol rich liquid in the absorption tower is continuously injected into the tower body 1, and the servo motor 4 is started to make the fan pipe 10 at the output end of the servo motor 4 start to work, so as to generate a negative pressure air duct, which is used to transport the gas generated inside the tower body 1 to the exhaust pipe 9 through the air duct to treat the gas. At the same time, when the triethylene glycol rich liquid enters the tower body 1 through the delivery pipe 5, the filtering and separation component 6 starts to treat the triethylene glycol rich liquid, and the guide pipe 61 first guides the triethylene glycol rich liquid to the filter 62, and after a layer of filtration, it flows to the next filter 62 through the bottom guide pipe 61. The triethylene glycol rich liquid after double-layer filtration flows to the collar pipe 63 through the guide pipe 61, and the box motor 3 is started, and the arc gear at the output end of the box motor 3 , meshing with the gear at one end of the 15-degree inclined roller 64, and rotating synchronously, the sleeve tube 63 is arranged at the bottom of the filter 62 and does not rotate. Since the sleeve tube 63 and the roller 64 are rotatably installed through a sealed bearing and are partially inside the roller 64, when the roller 64 at one end rotates, the triethylene glycol rich liquid flows into the inside of the roller 64 through the sleeve tube 63. At this time, the heating ring 65 continues to heat up before, and continuously heats the triethylene glycol rich liquid inside the roller 64. During the rolling of the roller 64, the triethylene glycol rich liquid is driven to roll inside to increase the heating surface. The triethylene glycol rich liquid quickly heats up inside the roller 64 to produce gas and sulfide. The air delivery pipe 67 on the fixed rotating shaft seat 66 at one end of the roller 64 is affected by the rotation of the fan blades inside the fan blade tube 10, and a negative pressure is generated to quickly absorb the gas generated inside the roller 64 from the inside of the roller 64 to the air delivery pipe 67, and transport it to the exhaust pipe 9 for gas treatment.

[0054] When the drum 64 rotates, the scraper 68 scrapes off the triethylene glycol rich liquid and sulfide residue on the inner wall of the drum 64 to prevent them from remaining on the inner wall of the drum 64, and the extension seat 613 at one end is fixed to one end of the fixed rotating shaft seat 66, and the extension seat 613 itself The spring and the fixing of the rotating seat continue to support the inner wall of the drum 64. At the same time, the rotating lever 615 rotates along with the inner wall of the drum 64. Every time it rotates one circle, it collides with the support plate 611 at the bottom. The support plate 611 is fanned at the front end of the positioning rod 612, and the elastic frames 614 installed at the upper and lower ends of the support plate 611 enable the support plate 611 to perform a short-term reciprocating fanning to provide a short-term power. Under the fanning of the support plate 611, the rotatably connected connecting block 610 moves. When the connecting block 610 moves, the vibrating plate 69 at one end fans, and the force generated by the fanning is transmitted to the scraper 68, thereby preventing the liquid from remaining on the surface and accelerating the flow of the liquid.

[0055] After the separation treatment by the two-layer roller 64, it flows to the impurity removal discharge component 7, and the triethylene glycol rich liquid flows to the infusion pipe valve 71 through the guide pipe 61, and flows into the interior of the liquid collecting bin 74 at one end through the infusion pipe valve 71. At this time, the triethylene glycol rich liquid is accumulated in the liquid collecting bin 74, and the pressure plate 79 is lifted up. When the pressure plate 79 moves upward, the magnet 78 produces a certain amount of lifting effect on the pressure plate 79. When the pressure plate 79 contacts the trigger block 77, the feedback button 73 presses downward and contacts The trigger rod 72 locks the inside of the infusion tube valve 71, closes the infusion, and the exhaust plate 75 delivers the produced carbon dioxide gas and rises to the top of the tower body 1. At this time, the oil cylinder 76 outputs and squeezes the pressure plate 79 downward. When the pressure plate 79 squeezes downward, the pressure plate 79 squeezes the spring seat 710 downward, and the triethylene glycol rich liquid is separated again through the molecular sieve 711. The triethylene glycol rich liquid after diversion flows into the next component through the tapered tube 712 for diversion treatment.

[0056] When the conical tube 712 inputs the separated triethylene glycol rich liquid into the electrode shunt assembly 8, the triethylene glycol rich liquid flows in through the top of the three-way tube 81 and covers the conductive paddle 82. At this time, the conductive paddle 82 is not charged. Affected by the continuous power transmission of the power box 85 on one side of the insulating compartment 83, the conductive rod 84 is charged, and the triethylene glycol liquid itself is not conductive. When the conductive rod 84 is connected to the conductive paddle 82, it means that when the triethylene glycol rich liquid is conductive, the triethylene glycol rich liquid contains water at this time, and the carbon dioxide gas and the sulfide are not completely separated. The conductive rod 84 drives the connecting rod 86 to move. When the connecting rod 86 moves, it drives the main gear 87 to rotate. When the main gear 87 rotates, the slave gear 88 at one end of the reflux pipe 813 rotates. When the slave gear 88 rotates, the rack 89 meshing at one end moves upward and rises. When the rack 89 rises, the baffle 810 at one end rises inside the bayonet slot 811. When the baffle 810 rises, it drives the extension frame 814 to move with it to ensure the airtightness of one side of the bayonet slot 811. With the effect of the limiting frame 815, when the main gear 87 rotates, the slave gear 88 of the discharge port 812 at the other end rotates to drive the rack 89 to descend. At the same time, the baffle 810 descends to the inside of the three-way pipe 81 to block the discharge port 812. At this time, the triethylene glycol rich liquid that has not been completely purified and separated will be transported to the delivery pipe 5 through the reflux pipe 813 for further processing, and the triethylene glycol rich liquid that has not been completely purified and separated will be continuously purified.

[0057] The present application also provides another technical solution: a method for using a natural gas triethylene glycol dehydration device, comprising the following steps:

[0058] S1: Connect the liquid discharge port of the absorption tower to the delivery pipe 5 at the top of the tower body 1, so that the triethylene glycol rich liquid from the absorption tower is injected into the interior of the tower body 1;

[0059] S2: The triethylene glycol rich liquid injected into the tower body 1 flows through the guide pipe 61 into the two-channel filter 62, and then is discharged to the drum 64 through the guide pipe 61;

[0060] S3: When the triethylene glycol is discharged into the drum 64, the box motor 3 rotates to drive the drum 64 to rotate, and at the same time, the heating ring 65 continuously heats the triethylene glycol rich liquid inside the drum 64, increasing the triethylene glycol rich liquid on the heating surface, and quickly generating gas and sulfide;

[0061] S4: The scraper 68 inside the drum 64 scrapes off the TEG rich liquid and derivatives on the inner wall of the drum 64 to prevent residues. The two layers of the drum 64 with different temperatures accelerate the speed at which the TEG rich liquid generates gas and sulfide inside. The gas is discharged from the tower body 1 through the gas pipe 67 and the fan pipe 10.

[0062] S5: The TEG rich liquid after the reaction in the drum 64 carries the reacted derivatives and sulfides and flows to the liquid collecting bin 74 for collection. When the pressing plate 79 contacts the trigger block 77, the liquid infusion is stopped, and the output end of the oil cylinder 76 squeezes the pressing plate 79 to make the TEG rich liquid pass through the molecular sieve 711, and the internal sulfides and water are separated from the TEG rich liquid.

[0063] S6: When the conical tube 712 inputs the re-separated triethylene glycol rich liquid into the electrode diversion assembly 8, the triethylene glycol rich liquid flows in through the top of the tee 81. When the triethylene glycol rich liquid contains water, the carbon dioxide gas and the sulfide are not completely separated. The conductive rod 84 drives the connecting rod 86 to move and transmits, driving the baffle 810 to descend to the inside of the tee 81 to block the discharge port 812. At this time, the triethylene glycol rich liquid that has not been purified and separated completely will be transported to the delivery pipe 5 through the reflux pipe 813 for reprocessing, and the triethylene glycol rich liquid that has not been purified and separated completely will be continuously purified.
