Description

Technical Field

[0001] This utility model relates to the field of natural gas production equipment technology, specifically to a pipeline liquid recovery device for natural gas production. Background Technology

[0002] Natural gas, as an important clean energy source, occupies a key position in the global energy supply system. During the production process of natural gas, after it is extracted from underground reservoirs, it often carries a certain amount of liquid, including formation water, condensate oil, and liquid hydrocarbons and hydrates formed during pipeline transportation due to temperature and pressure changes. In order to overcome the limitations of traditional pipeline liquid treatment methods, there is an urgent need to develop a new type of pipeline liquid recovery device for natural gas production.

[0003] Existing technology discloses a natural gas production pipeline sludge recovery device (publication number CN209068190U), comprising a natural gas pipeline connected to a sludge collection device. The sludge collection device includes an isolation cylinder, an isolation plate, an isolation grid, pipes, and valves. The end of the natural gas pipeline is connected to one side of the isolation cylinder, and the isolation plate is located inside the isolation cylinder. An isolation grid is located inside the isolation plate. The bottom of the isolation cylinder has an inclined structure, and its lower end is connected to the sludge treatment device via pipes and valves. A condenser pipe is also located inside the isolation cylinder, with both ends connected to the two sides of the isolation cylinder. The cold water inlet of the condenser pipe is connected to a water tank, and the hot water outlet of the condenser pipe is connected to a discharge cylinder. The bottom of the sludge treatment device is connected to the water tank via a recovery pipe and a recovery pump. This device enables the recovery and reuse of sludge.

[0004] The aforementioned natural gas production pipeline sludge recovery device increases the pH of the sludge, and the treated sludge is discharged into a water tank through a recovery pipe and a recovery pump. The dry ice generator cools the treated sludge, allowing it to enter the condenser tube for sludge recovery. However, the recovery pipe in the device is a standard straight pipe, not a spiral pipe, which prevents the natural gas from generating centrifugal force during flow to throw the heavier sludge against the outer wall of the pipe and into the external sludge collection tank. This results in poor performance and requires improvement. Utility Model Content

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A natural gas production pipeline liquid recovery device includes a natural gas pipeline 1, a centrifugal treatment device 2 is provided on the right side of the natural gas pipeline 1, and a liquid collection device 3 is provided at the bottom of the centrifugal treatment device 2.

[0025] The liquid collection device 3 includes a diversion discharge component 301, a stepper motor 302, a rotating shaft 303, a sealing plate 304, an impact plate 305, an impact rod 306, a connecting rectangular plate 307, an intermediate spring 308, a receiving plate 309, and a limiting ring 310. The diversion discharge component 301 is fixedly connected to the bottom of the liquid collection tank 204. The stepper motor 302 is fixedly connected to the bottom right side of the natural gas pipeline 1. The rotating shaft 303 is fixedly connected to the output shaft of the stepper motor 302. The limiting ring 310 is fixedly connected to the back of the diversion discharge component 301. The sealing plate 304 is fixedly connected to the surface of the rotating shaft 303. The impact plate 305 is fixedly connected to the front of the sealing plate 304. The impact rod... Part 306 is fixedly connected to the top of the impact plate 305. The connecting rectangular plate 307 is fixedly connected to the front of the diversion and discharge part 301. The intermediate spring part 308 is fixedly connected to the bottom of the connecting rectangular plate 307. The receiving plate part 309 is fixedly connected to the bottom of the intermediate spring part 308. The bottom of the diversion and discharge part 301 is provided with a drainage groove. The area of ​​the sealing plate part 304 is larger than the area of ​​the drainage groove. The drainage groove is designed to discharge liquid and collect the stored liquid into the outer shell. The inner diameter of the limiting ring part 310 is adapted to the diameter of the rotating shaft 303. The rotating shaft 303 is slidably connected to the inside of the limiting ring part 310. The right side of the back of the sealing plate part 304 is slidably connected to the surface of the limiting ring part 310.

[0026] The centrifugal treatment device 2 includes a pump body 201, a connecting pipe 202, a spiral pipe 203, a liquid collection tank 204, and a guide plate 205. The connecting pipe 202 is fixedly connected to the right side of the natural gas pipeline 1. The pump body 201 is fixedly connected to the right side of the connecting pipe 202. The spiral pipe 203 is fixedly connected to the bottom right side of the pump body 201. The liquid collection tank 204 is fixedly connected to the bottom of the spiral pipe 203. The guide plate 205 is fixedly connected to the top front of the liquid collection tank 204, and the back guide plate 205 is fixedly connected to the top back of the liquid collection tank 204. The bottom of the spiral pipe 203 has four small holes, which are aligned with the top center of the diversion discharge device 301. Under the action of gravity, the liquid flows through these small holes into a liquid collection tank 204 below. The small holes serve the purpose of liquid discharge, and each small hole corresponds to one liquid collection tank 204, enabling precise collection of the outflowing liquid.

[0027] In use, the centrifugal treatment device 2 on the right side of the natural gas pipeline 1 can centrifuge the accumulated liquid. At the bottom right side of the natural gas pipeline 1, where the accumulated liquid easily gathers, a special recovery unit is connected. This unit includes a spiral pipe 203 with a large diameter. After the natural gas carrying the accumulated liquid enters the spiral pipe 203, the spiral shape of the pipe generates centrifugal force during its flow, causing the heavier liquid to be thrown against the outer wall of the pipe. A series of small holes are opened at the bottom of the outer wall of the spiral pipe 203. Under the action of gravity, the liquid flows through these holes into a liquid collection tank 204 below. By designing the pipeline in a spiral shape, the centrifugal force generated during the flow of natural gas causes the heavier liquid to be thrown against the outer wall of the pipe and then flow into the external liquid collection tank 204. This design is effective, and the guide plate 205 further prevents leakage to other areas. The system treats and collects the accumulated liquid by centrifugation. A liquid collection device 3 is installed at the bottom of the centrifugation treatment device 2. After the accumulated liquid enters the liquid collection tank 204, it needs to be discharged when the tank is full. At this time, the stepper motor 302 can be started to drive the rotating shaft 303 to rotate counterclockwise, which moves the sealing plate 304 away from the bottom of the diversion discharge part 301. This allows the drainage groove at the bottom of the diversion discharge part 301 to be discharged, and the stored liquid can be collected into the outer shell. In order to prevent the liquid from staying at the bottom of the diversion discharge part 301, the stepper motor 302 can be started to rotate its output shaft in the opposite direction, which drives the sealing plate 304 to swing upward, so that the impact plate 305 and the impact rod 306 hit the bottom of the receiving plate 309. With the help of the intermediate spring 308, the shaking amplitude is increased, which helps to shake off the liquid adhering to the bottom of the inside, so as to avoid the odor caused by long-term retention and treat the accumulated liquid.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
