Description

Technical Field

[0001] This utility model relates to the technical field of drainage cooling devices, and in particular to a cooling device for drainage of gas wells. Background Technology

[0002] Natural gas, as a clean and efficient fossil fuel, occupies a crucial position in the global energy structure. Compared with traditional energy sources such as coal and oil, natural gas produces fewer pollutants and has a lower carbon emission intensity when burned, thus playing a key transitional role in the energy transition process.

[0003] Gas wells are crucial engineering facilities connecting underground natural gas reservoirs to surface gathering and transportation systems, and their importance is self-evident. Through a series of complex processes including drilling and well completion, gas wells can safely and efficiently guide natural gas resources buried deep underground to the surface. After purification and separation, this natural gas can be widely used in power generation, industrial fuel, urban gas supply, and many other fields, providing vital energy security for economic and social development.

[0004] In existing technologies, dehydration of traditional gas wells mainly relies on separate drying towers (such as molecular sieve adsorption devices) and drain valves. The working principle of this dehydration system is as follows: the natural gas is first dehydrated through the drying tower, and then the separated liquid is introduced into a storage tank through a dedicated pipeline. When the liquid in the storage tank accumulates to a certain amount, the valve needs to be manually opened to drain the liquid.

[0005] This traditional dehydration system is not only complex in its components, requiring multiple independent parts to work together, but also occupies a large area, causing numerous inconveniences for the construction and maintenance of gas wells. Furthermore, manual valve operation suffers from inefficiency and slow response times, making it difficult to meet the demands of modern automated gas well operation. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a cooling device for gas well drainage.

[0007] This utility model is achieved by the following technical solution: a cooling device for gas well drainage, including a flow guide pipe, a drainage component at the bottom of the flow guide pipe, and a cooling component inside the flow guide pipe.

[0008] The drainage assembly includes absorbent cotton, which is fixedly connected to the inner wall of the guide pipe. A guide channel is fixedly connected to the bottom of the guide pipe. A limit ring is fixedly connected to the inner wall of the guide channel. A second limit ring is fixedly connected to the inner wall of the guide channel. A rotating rod is rotatably connected to the inner wall of the guide channel. A sealing shaft is fixedly connected to the left side of the rotating rod. A sealing ring is fixedly connected to the surface of the sealing shaft. A limit housing is fixedly connected to the outer wall of the guide channel. A limit groove is formed on the inner wall of the limit housing. An unlocking rod is slidably connected to the inner wall of the limit groove. A rotating groove is formed on the surface of the rotating rod. A limit spring is fixedly connected to the left side of the unlocking rod.

[0009] As a further improvement to the above solution, the left side of the rotating rod penetrates the inner wall of the flow guide channel, the top of the sealing ring is in contact with the bottom of the limiting ring, the outer wall of the unlocking rod is slidably connected to the inner wall of the rotating groove, and the end of the limiting spring away from the unlocking rod is fixedly connected to the surface of the flow guide channel.

[0010] As a further improvement to the above solution, several absorbent cottons are provided, several flow guiding channels are provided, and two sealing rings are provided, with the two sealing rings arranged symmetrically about the rotating rod.

[0011] With the above technical solution, when the gas inside the guide pipe flows through the absorbent cotton, the moisture in the natural gas will be absorbed by the absorbent cotton. Under the action of gravity, the liquid flows along the guide channel of the absorbent cotton. At this time, the liquid is blocked by the sealing shaft and the sealing ring to prevent outflow. When it is necessary to discharge the liquid inside the guide channel, the unlocking rod is pushed into the limiting groove opened on the limiting shell.

[0012] As a further improvement to the above solution, the cooling assembly includes an air inlet, which is located on the left side of the guide pipe, and a cooling groove is formed on the inner wall of the air inlet.

[0013] As a further improvement to the above solution, an air outlet is provided on the right side of the guide pipe, and a diversion pipe is connected to the right side of the air inlet.

[0014] As a further improvement to the above solution, the end of the diverter pipe away from the air inlet is connected to the inner wall of the air outlet.

[0015] As a further improvement to the above solution, an inlet is provided at the top of the inner wall of the cooling tank, and an outlet is provided at the bottom of the inner wall of the cooling tank.

[0016] Through the above technical solution, natural gas enters into several branch pipes through the inlet, and then coolant is injected into the cooling tank opened in the guide pipe through the liquid inlet, so that the coolant cools the surface of the branch pipe and increases the contact area with the coolant in the cooling tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a novel method where, when gas flows through the absorbent cotton inside the guide pipe, the moisture in the natural gas is absorbed by the absorbent cotton. Under gravity, the liquid flows along the guide channel via the absorbent cotton. At this time, the liquid is blocked by the sealing shaft and sealing ring, preventing outflow. When it is necessary to drain the liquid from the guide channel, the unlocking rod is pushed into the limiting groove on the limiting housing. The unlocking rod moves linearly under the limiting action of the limiting groove. Simultaneously, the unlocking rod drives the protrusion to slide along the rotating groove on the rotating rod, and at the same time, the unlocking rod compresses the limiting spring in the direction of the guide channel. This causes the unlocking rod to rotate the rotating rod through the rotating groove, which in turn drives the sealing shaft. The sealing shaft then drives the symmetrically arranged sealing rings to rotate, causing the liquid inside the guide channel to flow outwards through the gap between the limiting ring and the second limiting ring. After the unlocking rod compresses the limiting spring to complete the drainage, the elastic potential energy of the spring automatically pushes the unlocking rod back to its original position, causing the sealing shaft and sealing ring to reseal the guide channel, preventing continuous leakage due to forgetting to close the door. This automatic reset design reduces human error and is especially suitable for the safety management of high-pressure gas wells.

[0019] This invention involves natural gas entering several distribution pipes through an inlet, and then coolant being injected into a cooling tank within the guide pipe through a liquid inlet. This coolant cools the surface of the distribution pipes, increasing the contact area with the coolant in the cooling tank and improving heat exchange efficiency compared to single-pipe flow. The coolant is then discharged through an outlet for circulating cooling. Subsequently, the natural gas inside the distribution pipes flows towards the right-side outlet, allowing the cooled natural gas to enter several absorbent cotton units for filtration of the accompanying liquid.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-8 A cooling device for draining fluid from a gas well, as described in this embodiment, includes a flow guide pipe 1, a draining component 2 at the bottom of the flow guide pipe 1, and a cooling component 3 inside the flow guide pipe 1.

[0033] The drainage assembly 2 includes absorbent cotton 201, which is fixedly connected to the inner wall of the guide pipe 1. A guide channel 202 is fixedly connected to the bottom of the guide pipe 1. A limit ring 203 is fixedly connected to the inner wall of the guide channel 202. A second limit ring 204 is fixedly connected to the inner wall of the guide channel 202. A rotating rod 205 is rotatably connected to the inner wall of the guide channel 202. A sealing shaft 206 is fixedly connected to the left side of the rotating rod 205. A sealing ring 207 is fixedly connected to the surface of the sealing shaft 206. A limit housing 208 is fixedly connected to the outer wall of the guide channel 202. A limit groove 209 is opened on the inner wall of the limit housing 208. An unlocking rod 210 is slidably connected to the inner wall of the limit groove 209. A rotating groove 211 is opened on the surface of the rotating rod 205. A limit spring 212 is fixedly connected to the left side of the unlocking rod 210.

[0034] The left side of the rotating rod 205 penetrates the inner wall of the flow channel 202, the top of the sealing ring 207 is in contact with the bottom of the limiting ring 203, the outer wall of the unlocking rod 210 is slidably connected to the inner wall of the rotating groove 211, and the end of the limiting spring 212 away from the unlocking rod 210 is fixedly connected to the surface of the flow channel 202.

[0035] Several absorbent cotton 201s are provided, several flow guiding channels 202 are provided, and two sealing rings 207s are provided, which are symmetrically arranged with the rotating rod 205 as the center.

[0036] The cooling assembly 3 includes an air inlet 301, which is located on the left side of the guide pipe 1, and a cooling groove 302 is provided on the inner wall of the air inlet 301.

[0037] An air outlet 303 is provided on the right side of the guide pipe 1, and a diversion pipe 304 is connected to the right side of the air inlet 301.

[0038] One end of the diverter pipe 304, away from the air inlet 301, is connected to the inner wall of the air outlet 303.

[0039] The cooling tank 302 has an inlet 305 at the top of its inner wall and an outlet 306 at the bottom of its inner wall.

[0040] The implementation principle of a cooling device for gas well drainage in this embodiment is as follows: Natural gas enters into several branch pipes 304 through the inlet 301, and then coolant is injected into the cooling tank 302 opened in the guide pipe 1 through the liquid inlet 305, so that the coolant cools the surface of the branch pipe 304, increasing the contact area with the coolant in the cooling tank 302. Compared with single-pipe flow, the heat exchange efficiency is increased. Then the coolant is discharged outward through the liquid outlet 306 for circulation cooling operation. Then, the natural gas inside the diversion pipe 304 flows towards the right outlet 303, allowing the cooled natural gas to enter several absorbent cottons 201, thereby filtering the liquid accompanying the natural gas. When the gas inside the guide pipe 1 flows through the absorbent cottons 201, the moisture in the natural gas is absorbed by the absorbent cottons 201, and the liquid flows along the guide channel 202 under the action of gravity. At this time, the liquid is blocked by the sealing shaft 206 and the sealing ring 207 to prevent outflow. When it is necessary to discharge the liquid inside the guide channel 202, the unlocking rod 210 is pushed towards the limit opening of the limiting shell 208. Pushing the locking rod 210 in the direction of the locking groove 209, the locking rod 210 moves linearly under the limiting action of the locking groove 209. Simultaneously, the locking rod 210 drives the protrusion to slide along the rotating groove 211 of the rotating rod 205, while the locking rod 210 compresses the limiting spring 212 in the direction of the guide channel 202. This causes the locking rod 210 to rotate the rotating rod 205 through the rotating groove 211. The rotating rod 205 drives the sealing shaft 206, which in turn drives the symmetrically arranged sealing rings 207 to rotate, causing the liquid inside the guide channel 202 to flow outwards along the gap between the limiting rings 203 and 204. After the locking rod 210 compresses the limiting spring 212 to complete the drainage, the elastic potential energy of the spring automatically pushes the locking rod 210 back to its original position, causing the sealing shaft 206 and sealing rings 207 to reseal the guide channel 202, preventing continuous leakage due to forgetting to close it. This automatic reset design reduces human error and is particularly suitable for the safety management of high-pressure gas wells.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
