Description

Technical Field

[0001] This utility model relates to the field of natural gas production technology, and in particular to a gas-liquid separation device for natural gas production. Background Technology

[0002] In a narrow sense, natural gas refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally deposited in the earth's strata. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is mainly hydrocarbons, but it also contains non-hydrocarbon gases. It is an important energy material, and its production and processing require gas-liquid separation.

[0003] Existing gas-liquid separation devices for natural gas have the following drawbacks: Gas-liquid separators are common natural gas gas-liquid separation devices, which mainly carry out the main gas-liquid separation process through internal umbrella-plate separators. In actual use, the liquid blocked by the separator needs to continuously condense into droplets before falling from the umbrella-plate separator. During the condensation process, as the gas rises, the un-converged liquid will also be carried out, requiring subsequent separators for separation. The separation efficiency is low. At the same time, the gaseous substances mixed in the droplets are not easy to be directly discharged. Therefore, we propose a gas-liquid separation device for natural gas production. Utility Model Content

[0004] The main objective of this invention is to provide a gas-liquid separation device for natural gas production. By using a separation mechanism installed inside the tank, the liquid at the bottom of the separator can be scraped and broken up, thereby improving the gas separation efficiency and quality and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gas-liquid separation device for natural gas production includes a tank and a separation mechanism. The separation mechanism is installed inside the tank and includes a feed pipe, a drain pipe, an exhaust pipe, a parapet separator A, a parapet separator B, a motor, a reducer, a drive shaft, an inclined plate, a brush, and a dispersing blade. The feed pipe is horizontally arranged on one side of the tank surface. The drain pipe and exhaust pipe are respectively arranged at the bottom and top of the tank. The parapet separator B is installed at the top of the tank. The motor is installed on the side of the tank surface away from the feed pipe, and the motor's power output end is equipped with a reducer. The drive shaft, which passes through the parapet separator B, is installed at the power output end of the reducer. An inclined plate is installed on the outer periphery of the drive shaft, and the surface of the inclined plate is provided with a brush that adheres to the bottom of the parapet separator B. A dispersing blade is installed on the outer periphery of the drive shaft at the bottom of the parapet separator B.

[0007] Furthermore, it also includes a transmission mechanism. A transmission mechanism is provided at the connection between the power output end of the reducer and the transmission shaft. The transmission mechanism includes a transmission box, an output shaft, bevel gear A, and bevel gear B. The transmission box is located inside the tank corresponding to the motor position. The power output end of the reducer is equipped with an output shaft extending into the transmission box, and bevel gear A is installed at the end of the output shaft. The bottom of the transmission shaft extends into the transmission box, and bevel gear B, which meshes with bevel gear A, is installed on the outer periphery of the transmission shaft inside the transmission box. The transmission box is located inside the tank. The power output from the motor is reduced by the reducer and discharged by the output shaft to drive the rotation of bevel gear A. Bevel gear B rotates under the action of bevel gear A and drives the operation of the transmission shaft and its peripheral components. Lubricating oil can be filled inside the transmission box to ensure lubrication between the gears. At the same time, the transmission box is an independent and closed structure, so natural gas will not enter the transmission box during processing, ensuring the sealing of the transmission components.

[0008] Furthermore, a baffle is welded inside the tank near the discharge end of the feed pipe, and an umbrella-plate separator A is installed at the bottom of the tank, located at the bottom of the baffle; the material discharged from the feed pipe is blocked by the baffle and falls to the umbrella-plate separator A.

[0009] Furthermore, a wire mesh demister is installed at the top of the tank near the exhaust pipe, and a guide ring is welded to the inner wall of the tank at the bottom of the umbrella plate separator B. The wire mesh demister can remove liquid droplets contained in the gas, achieving the final separation treatment of the gas. The guide ring structure allows the liquid that slides down the inner wall of the tank to be discharged into the rotation position of the dispersing blade.

[0010] Furthermore, a shaft seal is installed at the connection between the top of the transmission box and the transmission shaft; the shaft seal structure can ensure the sealing of the connection between the transmission shaft and the transmission box.

[0011] Furthermore, an oil inlet is provided on one side of the top of the transmission box, and an oil outlet is provided on one side of the bottom of the transmission box; lubricating oil can be injected into the transmission box through the oil inlet, and the oil can be discharged through the oil outlet.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The natural gas to be processed is discharged into the tank through the feed pipe. During the upward movement and discharge of the material, it comes into contact with the umbrella plate separator B. The umbrella plate separator B is used to separate the gas and liquid. The gaseous material continues to rise, while the liquid material adheres to the bottom of the umbrella plate separator B and continuously condenses. During the separation process, the drive shaft drives the rotation of the inclined plate and the dispersing blade. The inclined plate continuously brushes the bottom of the umbrella plate separator B with the brush at its bottom, promptly sweeping off the adhering liquid material to prevent it from being carried out by the gas. The falling liquid material is separated during the falling process. The paddle disperses the gas inside, thereby reducing the gas content in the liquid and improving the efficiency and quality of natural gas gas-liquid separation. Inside the tank, there is a transmission box. The motor output power is reduced by a reducer and then discharged through the output shaft to drive the rotation of bevel gear A. Bevel gear B rotates under the action of bevel gear A and drives the transmission shaft and its peripheral components. The transmission box can be filled with lubricating oil to ensure lubrication between the gears. At the same time, the transmission box is an independent and closed structure, so natural gas will not enter the transmission box during processing, ensuring the sealing of the transmission components.

The feed pipe 201 is horizontally arranged on one side of the tank 1. The drain pipe 202 and the exhaust pipe 203 are respectively installed at the bottom and top of the tank 1. A canopy separator B206 is installed at the top of the tank body 1. A motor 208 is installed on the surface of the tank body 1 away from the feed pipe 201, and a reducer 209 is provided at the power output end of the motor 208.

A dispersing blade 213 is installed on the outer periphery of the drive shaft 210 at the bottom of the canopy separator B206.

[0021] The system also includes a transmission mechanism 3. A transmission mechanism 3 is provided at the connection between the power output end of the reducer 209 and the transmission shaft 210. The transmission mechanism 3 includes a transmission box 301, an output shaft 302, a bevel gear A 303, and a bevel gear B 304. The transmission box 301 is located inside the tank 1, corresponding to the position of the motor 208. The power output end of the reducer 209 is fitted with an output shaft 302 extending into the transmission box 301, and the end of the output shaft 302 is fitted with a bevel gear A 303. The bottom of the transmission shaft 210 extends into the transmission box 301, and the outer periphery of the transmission shaft 210 is located within the transmission box 301. Inside the housing 301, a bevel gear B304 meshes with a bevel gear A303. Inside the tank 1, there is a transmission housing 301. The power output from the motor 208 is reduced by the reducer 209 and then discharged by the output shaft 302 to drive the rotation of the bevel gear A303. The bevel gear B304 rotates under the action of the bevel gear A303 and drives the transmission shaft 210 and its peripheral components. The transmission housing 301 can be filled with lubricating oil to ensure lubrication between the gears. At the same time, the transmission housing 301 is an independent and closed structure, so natural gas will not enter the transmission housing 301 during the processing, ensuring the sealing of the transmission components.

[0022] The tank body 1 has a baffle 205 welded inside near the discharge end of the feed pipe 201. A splitter A204 is installed at the bottom of the baffle 205 inside the tank body 1. A wire mesh demister 207 is installed at the top of the tank body 1 near the exhaust pipe 203. A guide ring 214 is welded to the inner wall of the tank body 1 at the bottom of the splitter B206. Material discharged from the feed pipe 201 is blocked by the baffle 205 and falls to the splitter A204. The wire mesh demister 207 removes liquid droplets from the gas, achieving final separation of the gas. The guide ring 214 allows liquid flowing down the inner wall of the tank body 1 to be discharged to the rotation position of the dispersing blade 213.

[0023] A shaft seal 305 is installed at the connection between the top of the transmission box 301 and the transmission shaft 210.

[0024] It should be noted that this utility model is a gas-liquid separation device for natural gas production. During operation, the natural gas to be processed is discharged into the tank 1 through the feed pipe 201. During the upward movement and discharge of the material, it comes into contact with the umbrella plate separator B206. The umbrella plate separator B206 separates the gas and liquid. The gaseous substance continues to rise, while the liquid substance adheres to the bottom of the umbrella plate separator B206 and continuously condenses. During the separation process, the drive shaft 210 drives the rotation of the inclined plate 211 and the dispersing blade 213. The inclined plate 211 continuously brushes the bottom of the umbrella plate separator B206 through the brush 212 at its bottom, promptly sweeping off the adhering liquid substance to prevent it from being carried out by the gas. The falling liquid substance will be separated during the falling process. The gas is dispersed by the dispersing blades 213, thereby discharging the gas mixed inside and reducing the gas content inside the liquid, thus improving the efficiency and quality of natural gas gas-liquid separation. Inside the tank 1, there is a transmission box 301. The power output of the motor 208 is reduced by the reducer 209 and discharged by the output shaft 302 to drive the rotation of the bevel gear A303. The bevel gear B304 rotates under the action of the bevel gear A303 and drives the transmission shaft 210 and its peripheral components. The transmission box 301 can be filled with lubricating oil to ensure lubrication between the gears. At the same time, the transmission box 301 is an independent and closed structure, so natural gas will not enter the transmission box 301 during processing, ensuring the sealing of the transmission components.
