Abstract
Description
Technical Field
[0001] This utility model belongs to the field of natural gas technology, specifically, it relates to a natural gas dehydration device. Background Technology
[0002] The natural gas flowing from the wellhead is almost entirely saturated with gaseous water, and may even carry a certain amount of liquid water. The presence of water in natural gas often has serious consequences. For example, natural gas containing CO2 and H2S can form acid in the presence of water, which can corrode pipelines and equipment. Under certain conditions, natural gas hydrates can form, which can block valves, pipelines and equipment. It can also reduce pipeline transport capacity and cause unnecessary power consumption.
[0003] A document with publication number (CN215757190U) discloses a natural gas dehydration device, including a shell. Two support legs are detachably provided at the bottom of the outer wall of the shell. An exhaust pipe for venting is provided at the top of the shell, and a drain pipe for draining wastewater is provided at the bottom. A top plate and a bottom plate are respectively inserted into the upper and lower ends of the shell. An exhaust hole for gas passage is opened in the middle of the top plate, and multiple drain holes for wastewater discharge are opened on the bottom plate. A windbreak plate is inserted between the top and bottom plates to shield the natural gas. A water-dissolving mesh is inserted between the top and bottom plates and located inside the windbreak plate for drainage. This device can effectively dehydrate water vapor in natural gas, ensuring the stable operation of the liquefaction unit, increasing the convenience and practicality of the natural gas dehydration device, and better meeting actual usage needs.
[0004] The aforementioned device treats moisture in natural gas through a water-dissolving mesh. However, the water-dissolving mesh can only hold a limited amount of moisture. The device proposes that the moisture on the water-dissolving mesh will drip out naturally after accumulating to a certain level. However, when the moisture on the water-dissolving mesh accumulates to the point where it can drip out, the mesh's ability to absorb moisture from the natural gas is already close to its peak. Therefore, in continuous natural gas dehydration processing, there is a problem of frequently replacing the water-dissolving mesh, making it unsuitable for continuous moisture treatment of natural gas.
[0005] In view of this, this utility model is proposed. Utility Model Content
[0006] To solve the technical problem of moisture removal from natural gas, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A natural gas dehydration device includes a processing tank with an installation position; a processing component installed inside the processing tank, the processing component being used to treat moisture in the natural gas, the processing component including a delivery pipe, an exhaust pipe, a condensation zone and a condensation pipe, the delivery pipe being fixedly connected to the processing tank, the condensation zone being fixedly connected to the inner wall of the processing tank, the delivery pipe passing through the condensation zone, and the exhaust pipe being fixedly connected to the top of the processing tank, the exhaust pipe being used to compress gas.

[0014] In a preferred embodiment of the present invention, a spring is sleeved on the fixed shaft block, and the ends of the spring are fixedly connected to the fixed shaft block and the first abutting block, respectively. The first abutting block is slidably connected to the fixed shaft block.
[0015] In a preferred embodiment of this utility model, a water-dissolving mesh is fixedly connected inside the treatment tank, a drain pipe is fixedly connected to the bottom of the treatment tank, and a hydrophobic porous membrane is fixedly connected inside the drain pipe.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. This natural gas dehydration device condenses natural gas in a condensation zone formed by a condensation zone and condensation pipes, and increases the flow path of natural gas by means of components in the condensation zone, thereby improving the efficiency of condensation and dehydration.
[0018] 2. This natural gas dehydration device increases the flow path of natural gas by guiding it with a guide block and increasing the space formed between the first plate, the second plate and the guide block. It also limits the flow rate of natural gas by using the first and second through holes to reduce the flow rate of natural gas and keep it in the cooling and condensing area where the condensing zone is located for a longer period of time, thereby increasing the condensation time of natural gas and improving the condensation effect.

[0020] 4. In this natural gas dehydration device, after the natural gas is compressed to a certain degree in the processing tank, the gas is retained in the processing tank for a long time, which prolongs the condensation time of the natural gas and improves the dehydration effect.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0031] Please see Figure 1-5 A natural gas dehydration device includes a processing tank 1 with an installation position; a processing component installed inside the processing tank 1, which is used to treat moisture in the natural gas. The processing component includes a delivery pipe 11, an exhaust pipe 2, a condensation zone 3, and a condensation pipe 31. The delivery pipe 11 is fixedly connected to the processing tank 1, the condensation zone 3 is fixedly connected to the inner wall of the processing tank 1, the delivery pipe 11 passes through the condensation zone 3, and the exhaust pipe 2 is fixedly connected to the top of the processing tank 1. The exhaust pipe 2 is used to compress gas and condense the natural gas through the condensation zone formed by the condensation zone 3 and the condensation pipe 31. The components in the condensation zone 3 increase the flow path of the natural gas and improve the efficiency of condensation and dehydration.
[0032] The condensation zone 3 has an annular cavity on its wall, and a condenser pipe 31 is installed in the annular cavity. The condenser pipe 31 is wound around the annular cavity of the condensation zone 3 and is fixedly connected to the inner wall of the condensation zone 3. The condenser pipe 31 cools the area where the condensation zone 3 is located, and the water in the natural gas is condensed by cooling, and the temperature is lowered to -140 to -160℃.
[0033] Within the condensation zone 3, a first plate 4 and a second plate 41 are fixedly connected. A flow guide block 42 is arrayed between the first plate 4 and the second plate 41, with the ends of the flow guide blocks 42 fixedly connected to the corresponding first plate 4 and second plate 41. The first plate 4 has a first through hole 44, each located on one side of the bottom of the corresponding flow guide block 42. The second plate 41 has a second through hole 45, each located on the other side of the end of the corresponding flow guide block 42. Multiple sets of second plates 41 and flow guide blocks 42 are arranged between them, and each set of second plates 41 and flow guide blocks 42... The gas is fixedly connected to the first plate 4. The gas moves upward from the bottom of the first plate 4. The gas moves upward through the first through hole 44 at the bottom. The flow path of the gas is increased by the guidance of the guide block 42 and the space formed between the first plate 4, the second plate 41 and the guide block 42. The flow rate of the gas is limited by the first through hole 44 and the second through hole 45. The flow rate of the gas is reduced, and the gas is kept in the cooling and condensing area where the condensing zone 3 is located for a long time, which increases the condensation time of the gas and improves the condensation effect. The condensed water is discharged downward through the corresponding first through hole 44 and second through hole 45.
[0034] A support column 43 is fixedly connected between the first plate 4 and the second plate 41. The middle of the support column 43 is penetrated by a conveying pipe 11. An exhaust block 13 is fixedly connected to the bottom of the conveying pipe 11. Exhaust slots 14 are arrayed on the exhaust block 13. Natural gas is sent into the exhaust block 13 through the conveying pipe 11. The exhaust slots 14 in the exhaust block 13 discharge the natural gas inside in batches. Through the synchronous discharge of multiple exhaust slots 14, the natural gas is fully dispersed. After being sent into the processing tank 1, the natural gas quickly and evenly enters the condensation zone 3, where it is quickly condensed and dehydrated.
[0035] The exhaust pipe 2 is fixedly connected to a fixed shaft block 21, and a first abutment block 23 is elastically connected to the fixed shaft block 21. A second abutment block 24 is fixedly connected to the exhaust pipe 2, and the first abutment block 23 and the second abutment block 24 abut against each other. The first abutment block 23 has holes arranged in an array. A spring 22 is sleeved on the fixed shaft block 21, and the ends of the spring 22 are fixedly connected to the fixed shaft block 21 and the first abutment block 23 respectively. The first abutment block 23 is slidably connected to the fixed shaft block 21. After the natural gas is compressed to a certain degree in the processing tank 1, the gas remains in the processing tank 1 for a long time, prolonging the cooling of the natural gas. The condensation time is reduced to improve the dehydration effect. When the natural gas is compressed to a certain extent, the first abutting block 23 is pushed upward, and the first abutting block 23 separates from the second abutting block 24. The dehydrated natural gas is discharged through the through hole on the first abutting block 23. When the natural gas in the treatment tank 1 is discharged to a certain extent, the pressure of the natural gas in the treatment tank 1 decreases. Because the first abutting block 23 compresses the spring 22, the spring 22 deforms and applies the deformation force to the first abutting block 23. The first abutting block 23 is pushed to make close contact with the second abutting block 24 again, sealing the space inside the treatment tank 1 and condensing the natural gas.
[0036] The treatment tank 1 is fixedly connected to a water-dissolving mesh 5, and the bottom of the treatment tank 1 is fixedly connected to a drain pipe 12. A hydrophobic porous membrane is fixedly connected inside the drain pipe 12. The natural gas in the treatment tank 1 is treated by dissolving water through the water-dissolving mesh 5. The water produced by the natural gas dehydration treatment is discharged to the bottom of the treatment tank 1 and discharged through the drain pipe 12 at the bottom. The hydrophobic porous membrane inside the drain pipe 12 discharges the water, and the natural gas remains in the treatment tank 1.
[0037] It is worth noting that, since hydrophobic porous membranes are a mature existing technology, the working principle of hydrophobic porous membranes has not been disclosed in detail and will not be elaborated here.
[0038] Working principle: Natural gas is fed into the exhaust block 13 through the delivery pipe 11. The exhaust channels 14 inside the exhaust block 13 discharge the natural gas out in batches. The synchronous discharge of multiple exhaust channels 14 fully disperses the natural gas. After being sent into the processing tank 1, the natural gas quickly and evenly enters the condensation zone 3, where it is rapidly condensed and dehydrated. The natural gas moves upward from the bottom of the first plate 4 through the corresponding first through hole 44. The flow path of the natural gas is increased by the guidance of the guide block 42 and the space formed between the first plate 4, the second plate 41 and the guide block 42. The flow rate of the natural gas is limited by the first through hole 44 and the second through hole 45, which reduces the flow rate and keeps the natural gas in the cooling and condensing area of the condensation zone 3 for a longer time, increasing the condensation time and improving the condensation effect. The condensed water is discharged downward through the corresponding first through hole 44 and second through hole 45 and cools the area of the condensation zone 3 through the condensation pipe 31. The cooling process further dehydrates the natural gas. Moisture condenses and cools to -140 to -160°C. After the natural gas is compressed to a certain extent in the treatment tank 1, the gas remains in the treatment tank 1 for a long time, prolonging the condensation time of the natural gas and improving the dehydration effect. When the natural gas is compressed to a certain extent, it pushes the first abutting block 23 upward, separating the first abutting block 23 from the second abutting block 24. The dehydrated natural gas is discharged through the through hole on the first abutting block 23. When a certain amount of natural gas is discharged from the treatment tank 1, the natural gas pressure in the treatment tank 1 decreases because the first abutting block 24... The abutment block 23 compresses the spring 22, causing the spring 22 to deform and apply the deformation force to the first abutment block 23. The first abutment block 23 is pushed to make close contact with the second abutment block 24 again, sealing the space inside the treatment tank 1, condensing the natural gas, and dissolving the natural gas in the treatment tank 1 through the water dissolving net 5. The water produced by the natural gas dehydration treatment is discharged to the bottom of the treatment tank 1 and discharged through the drain pipe 12 at the bottom. The hydrophobic porous membrane in the drain pipe 12 discharges the water, and the natural gas remains in the treatment tank 1.
