Description

Technical Field

[0001] This utility model relates to the field of oilfield equipment technology, and specifically discloses an associated gas condensate separation and collection device. Background Technology

[0002] Associated gas is an important byproduct in oil and gas field development. Associated gas typically contains components such as water vapor and heavy hydrocarbons, which condense into liquid during gathering and transportation due to temperature and pressure changes. If these condensates are not separated and discharged in a timely manner, they will accumulate in pipelines and equipment, increasing transport resistance, causing metering errors, exacerbating pipeline corrosion, and in severe cases, even forming liquid blockages, threatening safe production.

[0003] Existing gas-liquid separation devices mostly employ preliminary separation methods such as cyclone separation and baffle interception, which have limited efficiency in separating tiny droplets and cannot meet the requirements of high-efficiency processing. Although some devices have added fine separation elements such as wire mesh demisters, their installation is mostly done by bolt fixing, requiring tools for replacement and maintenance, which is cumbersome and time-consuming. Therefore, a device for separating and collecting associated gas condensate is needed to solve this problem. Utility Model Content

[0004] This invention proposes a gas-liquid separation and collection device that integrates three-stage high-efficiency separation and quick-lock maintenance functions. While significantly improving the gas-liquid separation efficiency and automation level, it greatly reduces the difficulty of maintaining and replacing core components.

[0005] This utility model is implemented as follows: a contaminated gas condensate separation and collection device includes a tank, an air inlet on the outer wall of the tank, an inner cylinder extending to the top of the tank fixedly connected inside the tank, an exhaust port extending to the outer wall of the tank fixedly connected to the side wall of the inner cylinder, a condensate outlet with a solenoid valve on the outer wall of the tank at the lower end of the tank, a spiral blade fixedly connected to the inner wall of the tank, a coalescing rectifier plate fixedly connected to the lower side of the inner wall of the tank via a connecting rod, a liquid level sensor provided on the lower side of the inner wall of the tank, a cover plate provided on the upper end face of the inner cylinder via a snap-fit ​​mechanism, and a wire mesh demister located inside the inner cylinder on the lower end face of the cover plate.

[0006] The locking mechanism includes a cavity inside the cover plate. Two limiting rods are fixedly connected to the inner wall of the cavity. Two symmetrically distributed sliding rods are slidably connected to the outer walls of the two limiting rods. The outer walls of the two sliding rods facing away from each other are fixedly connected to locking rods extending to the outside of the cover plate. The outer wall of the inner cylinder has two locking holes that match the locking rods. A second spring located between the two sliding rods is sleeved on the outer walls of the two limiting rods. A rotating shaft is rotatably connected inside the cavity. A gear is fixedly connected to the outer wall of the rotating shaft. A straight rack that meshes with the gear is fixedly connected to the opposite outer walls of the two sliding rods.

[0007] As a preferred embodiment of the associated gas condensate separation and collection device of this utility model, a groove is provided at the upper end of the outer wall of the inner cylinder, a limit ring is slidably connected inside the groove, and a first spring is fixedly connected between the inner wall of the groove and the limit ring.

[0008] As a preferred embodiment of the associated gas condensate separation and collection device of this utility model, a sealing ring is provided on the outer wall of the limiting ring near the cover plate.

[0009] In a preferred embodiment of the associated gas condensate separation and collection device of this utility model, the lower side of the clamping rod near the clamping hole is an inclined surface.

[0010] As a preferred embodiment of the associated gas condensate separation and collection device of this utility model, the upper end of the rotating shaft extends to the outside of the cover plate and is fixedly connected with a handle.

[0011] As a preferred embodiment of the associated gas condensate separation and collection device of this utility model, the outer wall of the tank is equipped with a controller, and the liquid level sensor and the solenoid valve are both electrically connected to the controller.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model employs a three-stage high-efficiency separation process: centrifugal separation with spiral blades, fine separation with coalescing rectifier plates, and final purification with a wire mesh demister. This process can capture droplets of different sizes step by step, significantly improving gas-liquid separation efficiency and ensuring the dryness of the associated gas at the outlet. Simultaneously, through the linkage control of a liquid level sensor and a solenoid valve, automatic discharge of condensate is achieved, ensuring continuous, stable, and reliable automated operation of the device.

[0014] 2. The snap-fit ​​mechanism enables quick assembly and disassembly of the wire mesh demister cover, simplifying and reducing the need for core consumable replacement, significantly lowering maintenance costs and shortening the time required. Furthermore, the design combining the spring-loaded limiting ring with the sealing ring effectively ensures a tight seal between the cover and the inner cylinder, preventing gas leakage and facilitating maintenance while maintaining the sealing performance of the separation chamber.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-5 A contaminated gas condensate separation and collection device includes a tank 1, an air inlet 2 on the outer wall of the tank 1, an inner cylinder 3 extending to the top of the tank 1 fixedly connected inside the tank 1, an exhaust port 4 extending to the outer wall of the tank 1 fixedly connected to the side wall of the inner cylinder 3, a condensate outlet 12 with a solenoid valve on the outer wall at the lower end of the tank 1, a spiral blade 9 fixedly connected to the inner wall of the tank 1, a coalescing rectifier plate 10 fixedly connected to the lower side of the inner wall of the tank 1 by a connecting rod, a liquid level sensor 11 on the lower side of the inner wall of the tank 1, a cover plate 5 on the upper end face of the inner cylinder 3 by a snap-fit ​​mechanism, and a wire mesh demister 8 located inside the inner cylinder 3 on the lower end face of the cover plate 5.

[0024] The locking mechanism includes a cavity 13 inside the cover plate 5. Two limiting rods 14 are fixedly connected to the inner wall of the cavity 13. Two symmetrically distributed sliding rods 15 are slidably connected to the outer walls of the two limiting rods 14. The outer walls of the two sliding rods 15 facing away from each other are fixedly connected to locking rods 16 extending to the outside of the cover plate 5. Two locking holes matching the locking rods 16 are opened on the outer wall of the inner cylinder 3. A second spring 17 located between the two sliding rods 15 is sleeved on the outer walls of the two limiting rods 14. A rotating shaft 18 is rotatably connected inside the cavity 13. A gear 19 is fixedly connected to the outer wall of the rotating shaft 18. A spur rack 20 that meshes with the gear 19 is fixedly connected to the opposite outer walls of the two sliding rods 15.

[0025] In this embodiment: the associated gas enters the annular space between the tank 1 and the inner cylinder 3 tangentially through the air inlet 2. Under the guidance of the spiral blades 9, it rotates and generates centrifugal force. Most of the larger droplets in the gas flow are thrown towards the inner wall of the tank 1 under the action of centrifugal force and coalesce on the wall to form a liquid film. The liquid film flows downward along the wall, completing the primary centrifugal separation. Then the gas flows downward and then upward through the coalescence rectifier plate 10, where the tiny droplets are captured, coalesced and drip down. At the same time, the gas flow is rectified. Then the gas enters the inner cylinder 3 and penetrates the wire mesh demister 8 from top to bottom, completing the final fine separation of the residual liquid. The purified gas is discharged from the exhaust port 4. All the separated condensate is collected at the bottom of the tank 1 and automatically discharged by the solenoid valve controlled by the liquid level sensor 11.

[0026] When replacing the wire mesh demister 8, the handle 21 is used to rotate the shaft 18, which drives the gear 19 to rotate. This, in turn, drives the two sliding rods 15 to slide relative to each other along the limiting rod 14 via the two racks 20. This, in turn, causes the two locking rods 16 to move relative to each other and disengage from the locking holes. The cover plate 5 and the wire mesh demister 8 can then be removed. The new cover plate 5 and the wire mesh demister 8 are then inserted downwards into the inner cylinder 3. When the locking rods 16 come into contact with the inner cylinder 3, the inner cylinder 3 presses the two locking rods 16 inwards and compresses the second spring 17. The cover plate 5 is rotated so that the locking rods 16 are aligned with the locking holes. Under the elastic force of the second spring 17, the locking rods 16 are locked into the locking holes, fixing the cover plate 5. Installation and disassembly are convenient.

[0027] As a technical optimization of this utility model, a groove is provided at the upper end of the outer wall of the inner cylinder 3, a limiting ring 6 is slidably connected inside the groove, and a first spring 7 is fixedly connected between the inner wall of the groove and the limiting ring 6.

[0028] In this embodiment: when the cover plate 5 is pressed into the inner cylinder 3, the limiting ring 6 is pressed against the lower side of the cover plate 5 under the elastic force of the first spring 7, so as to maintain good sealing between the cover plate 5 and the inner cylinder 3.

[0029] As a technical optimization of this utility model, a sealing ring is provided on the outer wall of the limiting ring 6 near the cover plate 5.

[0030] In this embodiment, the sealing ring facilitates maintaining a good seal between the limiting ring 6 and the cover plate 5.

[0031] As a technical optimization of this utility model, the lower side of the lever 16 near the card hole is a slope.

[0032] In this embodiment, by setting the lower side of the clamping rod 16 near the clamping hole as an inclined surface, it is easier to press the clamping rod 16 inward when the cover plate 5 is pressed into the inner cylinder 3, making installation more convenient.

[0033] As a technical optimization of this utility model, the upper end of the rotating shaft 18 extends to the outside of the cover plate 5 and is fixedly connected to a handle 21.

[0034] In this embodiment, the handle 21 facilitates the rotation of the shaft 18.

[0035] As a technical optimization of this utility model, a controller is provided on the outer wall of the tank 1, and the liquid level sensor 11 and the solenoid valve are electrically connected to the controller.

[0036] In this embodiment: the liquid level sensor 11 monitors the liquid level in the tank 1 in real time. When the liquid level rises to a specified value, it transmits a signal to the controller, which then opens the solenoid valve to discharge the condensate.

[0037] The working principle and usage process of this utility model: The associated gas enters the annular space between the tank 1 and the inner cylinder 3 tangentially through the air inlet 2. Under the guidance of the spiral blade 9, it rotates and generates centrifugal force. Most of the larger droplets in the gas flow are thrown towards the inner wall of the tank 1 under the action of centrifugal force, and coalesce on the wall to form a liquid film. The liquid film flows downward along the wall, completing the primary centrifugal separation. Then the gas passes downward and upward through the coalescence rectifier plate 10, where the tiny droplets are captured, coalesced and drip down. At the same time, the gas flow is rectified. Then the gas enters the inner cylinder 3 and penetrates the wire mesh demister 8 from top to bottom, completing the final fine separation of the residual liquid. The purified gas is discharged from the exhaust port 4. All the separated condensate is collected at the bottom of the tank 1 and automatically discharged by the solenoid valve controlled by the liquid level sensor 11.

[0038] When replacing the wire mesh demister 8, the handle 21 is used to rotate the shaft 18, which drives the gear 19 to rotate. This, in turn, drives the two sliding rods 15 to slide relative to each other along the limiting rod 14 via the two racks 20. This, in turn, causes the two locking rods 16 to move relative to each other and disengage from the locking holes. The cover plate 5 and the wire mesh demister 8 can then be removed. The new cover plate 5 and the wire mesh demister 8 are then inserted downwards into the inner cylinder 3. When the locking rods 16 come into contact with the inner cylinder 3, the inner cylinder 3 presses the two locking rods 16 inwards and compresses the second spring 17. The cover plate 5 is rotated so that the locking rods 16 are aligned with the locking holes. Under the elastic force of the second spring 17, the locking rods 16 are locked into the locking holes, fixing the cover plate 5. Installation and disassembly are convenient.
