Description

Technical Field

[0001] This invention relates to the field of natural gas processing technology, and more particularly to a natural gas deacidification device. Background Technology

[0002] Natural gas is a gas primarily composed of hydrocarbons such as methane. It is a clean and efficient fossil fuel, commonly used in power generation, heating, industrial production, and transportation. Vast natural gas resources are stored in underground rock formations. Through extraction, purification, and transportation, natural gas can be extracted from the ground and supplied to people. Natural gas has advantages such as high calorific value, low emissions, and ease of storage and transportation, thus playing an important role in the global energy structure. Natural gas deacidification refers to the process of removing acidic components from natural gas. These acidic components are mainly hydrogen sulfide and sulfur dioxide, as well as other sulfides and oxides. The purpose of deacidification is to reduce the content of acidic substances in natural gas to avoid corrosion of pipelines and equipment, while also improving the quality and utilization value of natural gas.

[0003] The amine process is a commonly used gas deacidification process suitable for natural gas containing acidic gases such as carbon dioxide and hydrogen sulfide. This process utilizes an amine solution to absorb the acidic gases, separating them from the natural gas through physical absorption and chemical reactions. However, most existing natural gas deacidification devices mix the natural gas with the amine solution to allow the solution to fuse the acidic gases. In practice, however, the mixing of natural gas and amine solution is often insufficient, resulting in a relatively poor deacidification effect. Furthermore, some moisture may mix with the natural gas during operation, further complicating the treatment process. Additionally, the amine solution accumulates more acidic gases over time, reducing its effectiveness and necessitating frequent replacement, thus diminishing the overall performance of the natural gas deacidification device. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a natural gas deacidification device.

[0005] This invention proposes a natural gas deacidification device, comprising a deacidification tower and a separation cylinder. The deacidification tower has an upper connecting box and a lower connecting box fixedly connected to its upper and lower ends, respectively. Two horizontal pipes are rotatably connected inside the deacidification tower, both horizontally arranged. Multiple stirring tubes are fixedly connected to the surface of each of the two horizontal pipes, and multiple gas outlet holes are provided on the surface of each stirring tube. A rotating mechanism for rotating the two horizontal pipes is provided on the surface of the deacidification tower. The separation cylinder is fixedly connected to the top of the upper connecting box and communicates with the interior of the deacidification tower.

Through the cooperation of two horizontal pipes and multiple stirring pipes, the natural gas delivered to the deacidification tower can be fully mixed with the solution inside during use, thereby facilitating the deacidification of the natural gas. At the same time, the solvent inside the deacidification tower is circulated and heated to release the acidic gas inside the solvent, allowing the solvent to be recycled. Simultaneously, the surface of the cooler is cooled, allowing the deacidified natural gas to be dehydrated again, thereby improving the efficiency of the device.

[0006] Preferably, the rotating mechanism includes gears, with a connecting shaft fixedly connected to one end of each of the two horizontal tubes. Each of the two connecting shafts is sleeved inside the deacidification tower at one end. Two gears are provided, each fixedly connected to one end of a connecting shaft and meshing with it. A side plate is fixedly connected to the surface of the deacidification tower near the two gears, and the side plate is disposed on the surface of the two gears. A reduction motor is mounted on the surface of the side plate, and the output shaft of the reduction motor is fixedly connected to the center of one of the gear surfaces. Two rotating... The connector has two horizontal pipes, one end of which is installed on one end of two rotary joints. The deacidification tower has a feed pipe at the end away from the two gears. The feed pipe is horizontally positioned and has two feed branch pipes fixedly connected to one end. The two feed branch pipes are installed at the other end of the two rotary joints. Valves are installed on the surface of the two feed branch pipes to drive the two horizontal pipes and multiple stirring pipes on the surface to rotate, thereby creating a stirring effect at the bottom of the deacidification tower and fully mixing the natural gas delivered to the deacidification tower, thus improving the deacidification effect of the natural gas.

[0007] Furthermore, the scraping mechanism includes scrapers, a rotating shaft is vertically rotatably connected inside the deacidification tower, a first horizontal plate and a second horizontal plate are provided inside the deacidification tower, both of which are horizontally arranged, the bottom end of the rotating shaft is rotatably connected to the top of the first horizontal plate, the rotating shaft is sleeved inside the second horizontal plate, the top end of the rotating shaft is rotatably connected to the center of the bottom of the conical baffle, a worm gear is sleeved on the surface of the rotating shaft, and a worm is sleeved on the surface of one of the horizontal pipes, the worm gear and the worm cooperate with each other, two scrapers are provided, both scrapers are rotatably connected to the bottom of the conical baffle, both scraper surfaces are fixedly connected to connecting rods, and both connecting rods are fixedly connected to the surface of the rotating shaft. The conical baffle is used to block the moisture inside the natural gas when it passes through after deacidification, thereby reducing the moisture content inside the natural gas. During use, both scrapers can be rotated simultaneously, which facilitates the removal of water vapor at the bottom of the conical baffle, thereby better dehydrating the natural gas.

[0008] Preferably, the water vapor separation mechanism includes a cooler. A fixed box is fixedly connected to the arc surface of the separation cylinder, and the fixed box is connected to the interior of the separation cylinder. The cooler is installed inside the fixed box. A condensing plate is fixedly connected inside the separation cylinder. The condensing plate is circular and fits against the inner wall of the separation cylinder. The condensing plate is installed on the surface of the cooler. Multiple heat sinks are arranged vertically inside the fixed box and are installed on the surface of the cooler. The upper and lower ends of the fixed box are conical. An exhaust pipe is fixedly connected to the top of the fixed box. The cooler cools the condensing plate, and when natural gas passes through, the moisture inside the natural gas condenses on the surface of the condensing plate, thereby reducing the moisture content of the natural gas and improving the treatment effect of the natural gas.

[0009] Furthermore, a first connecting pipe is fixedly connected to the center of the bottom of the lower connecting box. A first suction pump is installed at one end of the first connecting pipe and is located at the bottom of the deacidification tower. A second connecting pipe is installed on the surface of the first suction pump, and the top end of the second connecting pipe is located on the surface of the fixed box. The connection between the second connecting pipe and the fixed box is located at the top of multiple heat sinks. Fixed plates are horizontally fixedly connected to both sides of the surface of the deacidification tower. Support frames are fixedly connected to the surfaces of both fixed plates.

One end of the fourth connecting pipe is fixedly connected to the surface of the cooling box and communicates with the interior of the cooling box. Two spray pipes are installed inside the deacidification tower, both horizontally positioned at the top of two horizontal pipes. Multiple spray heads are installed at the bottom of each spray pipe. One end of each spray pipe is inserted through one side of the deacidification tower surface and is fixedly connected to the same connecting branch pipe. The top of the third connecting pipe is fixedly connected to the surface of the connecting branch pipe. This third connecting pipe circulates the solvent at the bottom of the deacidification tower and simultaneously transports the solvent to the fixed box, passing between multiple heat sinks on the cooler. This cools the heat generated by the cooler during operation and simultaneously heats the solvent, making it easier for the acidic gases inside to evaporate.

[0010] In this invention, the natural gas requiring deacidification can be connected to one end of the feed pipe via a pipeline. Then, the valves on the surfaces of the two feed branch pipes are opened, allowing the gas requiring deacidification to be transported through the two feed branch pipes and the two valves into the two horizontal pipes. Subsequently, the geared motor is driven, and the two horizontal pipes rotate simultaneously under the connection of two gears. Then, under the action of multiple stirring pipes, the natural gas requiring deacidification is transported into the deacidification tower and can be mixed with the solvent inside the deacidification tower. At the same time, the rotation of the two horizontal pipes and multiple stirring pipes makes the natural gas and solvent transported into the deacidification tower more thoroughly mixed.

[0011] At the same time, the worm gear will drive the worm wheel to rotate, and through the connection of the rotating shaft and the two connecting rods, the two scrapers will scrape away the water at the bottom of the conical baffle.

[0012] The first suction pump drives the solvent at the bottom of the deacidification tower to be transported to the fixed box through the first and second connecting pipes. Under the action of multiple heat sinks, the solvent machine is heated. After the solvent is heated, the acidic gas inside the solvent is released, and the multiple heat sinks are cooled down at the same time.

[0013] The cooling tank can cool the solvent, and the second suction pump can transport the solvent inside the cooling tank to the two connecting branches through the third connecting pipe and the connecting branch pipe. The solvent is then sprayed out through multiple spray nozzles, thereby circulating the solvent and improving the effectiveness of the device. Attached Figure Description

[0027] Reference Figure 6 and Figure 7In a preferred embodiment, the water vapor separation mechanism includes a cooler 8. A fixed box 3 is fixedly connected to the arc surface of the separation cylinder 2, and the fixed box 3 is connected to the interior of the separation cylinder 2.

[0028] Reference Figure 6 , Figure 7 and Figure 8In a preferred embodiment, a first connecting pipe 61 is fixedly connected to the center of the bottom of the lower connecting box 12. A first suction pump 6 is provided at one end of the first connecting pipe 61. The first suction pump 6 is located at the bottom of the deacidification tower 1. A second connecting pipe 62 is provided on the surface of the first suction pump 6. The top end of the second connecting pipe 62 is located on the surface of the fixed box 3.

A second suction pump 9 is located between the deacidification tower 1 and the cooling box 4. A third connecting pipe 91 and a fourth connecting pipe 95 are mounted on the surface of the second suction pump 9. One end of the fourth connecting pipe 95 is fixedly connected to the surface of the cooling box 4 and communicates with the interior of the cooling box 4. Two spray pipes 93 are installed inside the deacidification tower 1. Both spray pipes 93 are horizontally arranged and located at the top of two horizontal pipes 7. Multiple spray heads 94 are installed at the bottom of each spray pipe 93. One end of each spray pipe 93... Two spray pipes 93 are fixedly connected to the same connecting branch pipe 92 at one end, and the top end of the third connecting pipe 91 is fixedly connected to the surface of the connecting branch pipe 92. The third connecting pipe 91 is used to circulate the solvent at the bottom of the deacidification tower 1 and transport the solvent to the inside of the fixed box 3. The solvent passes between the multiple heat sinks 82 on the cooler 8, thereby cooling the heat generated by the cooler 8 when it is working. At the same time, the solvent is heated, making it easier for the acidic gas inside to evaporate.

[0029] In this invention, the coordinated arrangement of two horizontal pipes 7 and multiple stirring pipes 71 facilitates thorough mixing of the natural gas supplied to the deacidification tower 1 with the internal solution, thereby promoting deacidification of the natural gas. Simultaneously, the solvent inside the deacidification tower 1 is circulated and heated, releasing acidic gases and allowing for solvent recycling. This also cools the surface of the cooler 8, further dehydrating the deacidified natural gas and improving the overall efficiency of the device. The deacidification tower 1 contains a solvent capable of absorbing acidic gases. During use, the gas requiring deacidification can be connected to one end of the feed pipe 5 via a pipeline, and then the valves 52 on the surfaces of the two feed branch pipes 51 can be opened. The gas to be deacidified is then fed into the two horizontal pipes 7 through two feed branch pipes 51 and two valves 52. The geared motor 74 is then driven, and the two horizontal pipes 7 rotate simultaneously under the connection of two gears 73. With the action of multiple stirring pipes 71, the natural gas to be deacidified is mixed with the solvent inside the deacidification tower 1. The rotation of the two horizontal pipes 7 and the multiple stirring pipes 71 further ensures thorough mixing of the natural gas and solvent. The natural gas is then conveyed upwards, where it is blocked by a conical baffle 21, which also reduces the moisture content within the natural gas. The gas then passes through the conical baffle... The baffle 21 is conveyed upwards, and the worm gear 75 drives the worm wheel 101 to rotate. Through the connection of the rotating shaft 100 and the two connecting rods 103, the two scrapers 102 scrape away the water at the bottom of the conical baffle 21, and at the same time drive the cooler 8 to work. Then, through the action of the condensing plate 81, the water inside the natural gas is condensed, thereby greatly reducing the water vapor inside the natural gas. The processed natural gas can then be transported through the discharge pipe 23 at the top of the separator 2. During use, the first suction pump 6 and the second suction pump 9 are driven. The drive of the first suction pump 6 causes the solvent at the bottom of the deacidification tower 1 to be transported to the fixed box 3 through the first connecting pipe 61 and the second connecting pipe 62. Inside, the solvent generator is heated by multiple heat sinks 82, which releases acidic gases from the solvent and cools the heat sinks 82. The separated acidic gases are then transported through the exhaust pipe 31, while the heated solvent is transported to the cooling box 4 through the collection pipe 41. The cooling box 4 is a conventional technology that cools the solvent. The second suction pump 9 transports the solvent inside the cooling box 4 to the two connecting branch pipes 92 through the connection of the third connecting pipe 91 and the connecting branch pipe 92, and sprays it out through multiple spray nozzles 94, thus circulating the solvent and improving the efficiency of the device.
