Description

Technical Field

[0001] This utility model relates to the field of natural gas dehydration technology, specifically to a natural gas dehydration device. Background Technology

[0002] Natural gas refers to all gases that exist naturally in the world, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. It is a high-quality fuel and chemical raw material. Natural gas needs to be dehydrated before use. A common dehydration method is solvent absorption, which typically involves reacting a triethylene glycol solution with the water in the natural gas to achieve dehydration.

[0003] In existing dehydration devices, when using solvents to dehydrate natural gas, the natural gas is drawn into a container containing solvent to bring it into contact with the solvent for dehydration. However, existing dehydration devices have limited functionality and cannot agitate the natural gas and triethylene glycol solution, thus failing to ensure sufficient contact between the natural gas and the triethylene glycol solution. Utility Model Content

[0004] The purpose of this invention is to provide a natural gas dehydration device that solves the problem that existing dehydration devices have limited functionality and cannot stir natural gas and triethylene glycol solution, thus failing to ensure sufficient contact between natural gas and triethylene glycol solution.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A natural gas dehydration device includes a dehydration tower. The side wall of the dehydration tower is provided with an inlet pipe and an outlet pipe, and the top and bottom of the tower are provided with an outlet pipe and an inlet pipe, respectively. The dehydration tower is provided with a dispersion plate, and dispersion holes are evenly opened on the dispersion plate. A one-way valve is provided in the dispersion hole. A vertically arranged rotating rod is rotatably provided on the top of the dispersion plate. The upper and lower ends of the rotating rod are provided with fan blades and stirring rods, respectively, and the horizontal height of the fan blades is higher than the horizontal height of the inlet pipe.

[0007] A further technical solution is to install a condenser tube below the dispersion plate inside the dehydration tower. Both ends of the condenser tube are sealed and penetrate the bottom wall of the dehydration tower, and are connected to a circulating pump box.

[0008] A further technical solution is to have a water outlet pipe connected to the inside of the dehydration tower at the bottom, and a water outlet valve on the water outlet pipe.

[0009] A further technical solution is to have the top of the air inlet pipe protrude from the inner bottom wall of the dehydration tower.

[0010] A further technical solution is to have multiple layers of condenser tubes, with each layer arranged in a spiral shape resembling a mosquito coil.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In use, natural gas enters the dehydration tower and, under pressure, passes through a one-way valve into the interior of the dehydration tower located above the dispersion plate. The natural gas comes into contact with triethylene glycol, which absorbs the moisture in the natural gas. The rising natural gas drives the fan blades to rotate, and the rotation of the fan blades drives the stirring rod to rotate. The rotation of the stirring rod can stir and mix the natural gas and triethylene glycol, ensuring that the natural gas and triethylene glycol are in full contact, so that the triethylene glycol can fully absorb the moisture in the natural gas.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example 1

[0019] Reference Figure 1 , Figure 2As shown, this utility model discloses a natural gas dehydration device, including a dehydration tower 1. The side wall of the dehydration tower 1 is provided with an inlet pipe 2 and an outlet pipe 3, and the top and bottom of the tower are provided with an outlet pipe 4 and an inlet pipe 5, respectively. It should be noted that the inlet pipe 2 and outlet pipe 3, and the outlet pipe 4 and inlet pipe 5 are respectively provided with an inlet valve 16, an outlet valve 17, an inlet valve 18, and an outlet regulating valve 19. The dehydration tower 1 is provided with a dispersion plate 6, and dispersion holes 7 are evenly opened on the dispersion plate 6. A one-way valve 8 is provided in the dispersion holes 7. The top of the dispersion plate 6 is provided with a vertically arranged rotating rod 9. The upper and lower ends of the rotating rod 9 are respectively provided with a fan blade 10 and a stirring rod 11, and the horizontal height of the fan blade 10 is higher than the horizontal height of the inlet pipe 2.

[0020] Specifically, during use, the operator connects the gas supply equipment to the inlet valve 18 using a pipe, and connects the liquid supply equipment to the inlet valve 16 using a pipe to deliver triethylene glycol into the dehydration tower 1. The inlet valve 16 is opened to allow triethylene glycol to flow into the dehydration tower 1 from the inlet pipe 2. Then, the inlet valve 18 is opened to allow natural gas to enter the dehydration tower 1. Under pressure, the natural gas passes through the check valve 8 and enters the interior of the dehydration tower 1 located above the dispersion plate 6. The natural gas comes into contact with the triethylene glycol, which absorbs the moisture from the natural gas. The rising natural gas drives the fan blade 10 to rotate. The rotation of the fan blade 10, through the rotating rod 9, drives the stirring rod 11 to rotate. The rotation of the stirring rod 11 stirs and mixes the natural gas and triethylene glycol, ensuring sufficient contact and allowing the triethylene glycol to fully absorb the moisture from the natural gas. The outlet regulating valve 19 is opened, allowing the dehydrated natural gas to be discharged through the outlet pipe 4. The outlet valve 17 is opened, allowing the moisture-absorbed triethylene glycol to be discharged through the outlet pipe 3.

[0021] By setting the dispersion holes 7, the natural gas entering the dehydration tower 1 can pass through the dispersion plate 6 evenly, which can disperse the natural gas and increase the contact area between the natural gas and triethylene glycol. By setting the one-way valve 8, the triethylene glycol solution can be prevented from flowing into the bottom of the dehydration tower 1 through the dispersion holes 7.

[0022] Example 2

[0023] Based on the aforementioned Embodiment 1, referring to Figure 1 , Figure 2As shown, a condenser tube 12 is installed below the dispersion plate 6 inside the dehydration tower 1. A support rod can be installed inside the dehydration tower 1 to reinforce and support the condenser tube 12. Both ends of the condenser tube 12 are sealed and penetrate the bottom wall of the dehydration tower 1, and are connected to a circulation pump box 13. The two ends of the condenser tube 12 are connected to the circulation pump box 13. The circulation pump box 13 integrates a liquid storage tank, a circulation pump, a temperature control device, and a pipeline interface. It is responsible for storing the cooling medium, providing power to transport the medium to the condenser tube 12, and recovering the high-temperature medium after heat absorption and cooling it again to form a closed loop. This is common technical knowledge for those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge. It will not be described in detail here.

[0024] Specifically, during use, after natural gas enters the dehydration tower 1, it first comes into contact with the condenser tube 12. The condenser tube 12 condenses the water in the natural gas into liquid water. The liquid water drips and settles at the bottom of the dehydration tower 1 under the action of gravity, thereby achieving the pretreatment of the water in the natural gas.

[0025] As a preferred implementation method, refer to Figure 1 , Figure 2 As shown, the bottom side of the dehydration tower 1 is provided with a water outlet pipe 14 that is connected to the interior of the dehydration tower 1. The water outlet pipe 14 is provided with a water outlet valve 15. Specifically, by setting the water outlet pipe 14, it is convenient to discharge the water deposited at the bottom of the dehydration tower 1. By setting the water outlet valve 15, it is prevented that the natural gas will escape from the water outlet pipe 14 when the natural gas is dehydrated.

[0026] As a preferred implementation method, refer to Figure 1 , Figure 2 As shown, the top of the air inlet pipe 5 protrudes from the inner bottom wall of the dehydration tower 1. Specifically, by making the air inlet pipe 5 protrude from the inner bottom wall of the dehydration tower 1, water deposited at the bottom of the dehydration tower 1 is prevented from flowing into the air inlet pipe 5.

[0027] Example 3

[0028] Based on the aforementioned Embodiment 2, referring to Figure 2 , Figure 3 As shown, the condenser tubes 12 are arranged in multiple layers, and each layer of condenser tubes 12 is arranged in a mosquito coil spiral shape. Specifically, by arranging the condenser tubes 12 in multiple layers, and each layer is arranged in a mosquito coil spiral shape, the area of ​​the condenser tubes 12 is increased, thereby increasing the contact area between natural gas and the condenser tubes 12 and improving the effect of pretreatment of natural gas.

[0029] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
