Description

TECHNICAL FIELD

[0001] The utility model relates to oil extraction equipment technical field, concretely is a kind of gas-liquid separation device for pipeline gas detection. BACKGROUND

[0002] At present, the method for detecting hydrogen sulfide content in gas-liquid produced by oil well in oil field is mostly direct detection by detector. The detector is divided into pump suction type and diffusion type. Once liquid enters the equipment during the detection process, it is easy to cause sensor failure, which seriously affects the accuracy of detection. In oil extraction equipment, gas-liquid separation device plays a crucial role. It can effectively separate the gas phase and liquid phase in the multi-phase mixture of oil, gas and water produced by oil well to meet the different processing and production needs of the subsequent process.

[0003] The Chinese utility model patent with publication number CN221432510U discloses a gas-liquid separation device related to the technical field of gas treatment. The gas-liquid separation device includes a device body, an air inlet pipe and an air outlet pipe. The air inlet pipe and the air outlet pipe are connected to the device body. The device body is internally provided with baffles and a chamber. The chamber is provided with packing. The baffles are arranged between the air inlet pipe and the chamber. The chamber is arranged between the baffles and the air outlet pipe. One of the baffle plates is perpendicular to the extension direction of the air inlet pipe towards the end of the baffle plate. The baffles are sequentially provided with multiple baffle plates. The lower edge of the lowest baffle plate is lower than the lower edge of the air inlet pipe connection. The upper edge of the highest baffle plate is higher than the upper edge of the air inlet pipe connection. The utility model surrounds the area containing the packing through the mesh plate between the baffles and the chamber, the mesh plate between the chamber and the air outlet pipe, and the inclined plate. On the one hand, the mesh plate can prevent the packing from leaking out. On the other hand, it can also facilitate the uniform flow of gas. The accumulated liquid on the inclined plate can also flow out through the mesh plate between the baffles and the chamber.

[0004] However, during use, although the baffles can achieve a certain gas-liquid separation effect, a large amount of gas in the liquid cannot be discharged, which easily causes uneven gas-liquid separation, cannot meet the production needs, and therefore a gas-liquid separation device for pipeline gas detection is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model provides a gas-liquid separation device for pipeline gas detection, which has the advantages of good gas-liquid separation effect, solves the problem that although the baffles can achieve a certain gas-liquid separation effect, a large amount of gas in the liquid cannot be discharged, which easily causes uneven gas-liquid separation and cannot meet the production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas-liquid separation device for pipeline gas detection, comprising a separation tank and a sealing cover plate fixedly installed on the top of the separation tank, wherein a detachable stirring mechanism extending into the top of the sealing cover plate is provided.

[0007] The detachable stirring mechanism includes a drive motor fixedly installed on the top of the sealing cover plate. A docking shaft extending into the interior of the separation tank is fixedly connected to the output shaft of the drive motor. A rotating shaft is provided at the end of the docking shaft away from the drive motor. A threaded block extending into the interior of the rotating shaft is fixedly connected to the bottom end of the docking shaft. Stirring blades are fixedly installed on the outside of the rotating shaft.

[0008] Furthermore, the docking shaft is rotatably connected to the sealing cover plate, and the docking shaft is threadedly connected to the rotating shaft via a threaded block.

[0009] Furthermore, an inclined plate is rotatably connected to the inner wall of the separation tank, a fixing block is fixedly connected to the inner wall of the separation tank, and a return spring is fixedly connected between the inclined plate and the fixing block.

[0010] Furthermore, there are two inclined plates, which are symmetrically distributed inside the separation tank, and the rotation shaft is located between the two inclined plates.

[0011] Furthermore, a demister is snapped into the inside of the sealing cover, the docking shaft passes through the demister and is slidably connected to it, and a handle is fixedly installed at the bottom of the demister.

[0012] Furthermore, an inlet pipe extending into the interior of the separation tank is fixedly connected to one side of the separation tank, and an outlet pipe communicating with the separation tank is fixedly connected to the top of the sealing cover.

[0013] Furthermore, a drain pipe connected to the bottom of the separation tank is fixedly connected to its interior, and a valve is fixedly installed on the outside of the drain pipe.

[0014] Compared with the prior art, this utility model provides a gas-liquid separation device for pipeline gas detection, which has the following beneficial effects:

[0015] 1. This gas-liquid separation device for pipeline gas detection uses a drive motor to rotate the docking shaft and the rotating shaft. The rotating shaft then drives the stirring blades to rotate, which slowly stirs the liquid inside the separation tank and gradually squeezes out the gas inside, thus achieving a good gas-liquid separation effect. Furthermore, the use of threaded blocks facilitates the disassembly of the docking shaft and the rotating shaft, making it easy to remove the demister and achieving a convenient disassembly effect.

[0016] 2. This gas-liquid separation device for pipeline gas detection, by setting up an inclined plate, allows gas to collide with the inclined plate when it flows upward, causing some liquid to adhere to the surface of the inclined plate, thus achieving the effect of gas-liquid separation. This further improves the efficiency of gas-liquid separation and solves the problem that although baffles can achieve a certain gas-liquid separation effect, a large amount of gas in the liquid still cannot be discharged, which easily leads to uneven gas-liquid separation and fails to meet production needs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This embodiment of a gas-liquid separation device for pipeline gas detection includes a separation tank 1 and a sealing cover plate 2 fixedly installed on the top of the separation tank 1. The top of the sealing cover plate 2 is provided with a detachable stirring mechanism extending into it. The detachable stirring mechanism includes a drive motor 3 fixedly installed on the top of the sealing cover plate 2. A docking shaft 4 extending into the interior of the separation tank 1 is fixedly connected to the output shaft of the drive motor 3. A rotating shaft 5 is provided at the end of the docking shaft 4 away from the drive motor 3. A threaded block 6 extending into the interior of the rotating shaft 5 is fixedly connected to the bottom end of the docking shaft 4. A stirring blade 7 is fixedly installed on the outside of the rotating shaft 5.

[0024] The docking shaft 4 is rotatably connected to the sealing cover plate 2, and the docking shaft 4 is threadedly connected to the rotating shaft 5 through the threaded block 6. The sealing cover plate 2 is internally fixed with a bearing that is compatible with the docking shaft 4.

[0025] It should be noted that a controller is fixedly installed on the front of the separation tank 1, and the drive motor 3 is a geared motor, which has the effect of slow rotation.

[0026] In this embodiment, an inclined plate 8 is rotatably connected to the inner wall of the separation tank 1, a fixing block 9 is fixedly connected to the inner wall of the separation tank 1, and a return spring 10 is fixedly connected between the inclined plate 8 and the fixing block 9. There are two inclined plates 8, which are symmetrically distributed inside the separation tank 1, and the rotating shaft 5 is located between the two inclined plates 8.

[0027] In this design, by setting a reset spring 10, when the operator removes the sealing cover 2, the stirring blade 7 will squeeze the inclined plate 8, causing the inclined plate 8 to rotate, making it easier to remove the sealing cover 2. Then, due to the action of the reset spring 10, the inclined plate 8 will return to its original position. By setting the inclined plate 8, when the gas flows upward, it can collide with the inclined plate 8, thereby causing some liquid to adhere to the surface of the inclined plate 8, achieving the effect of gas-liquid separation.

[0028] In this embodiment, a demister 11 is snapped into the inside of the sealing cover plate 2. A connecting shaft 4 passes through and slidably connects to the demister 11. A handle is fixedly installed at the bottom of the demister 11. A large number of fine fibers, such as glass fiber and polyester fiber, are used as the filter medium. When the airflow containing mist droplets passes through these fibers, demisting is achieved based on the fiber filtration principle. The demisting efficiency is high and it can adapt to different airflow speeds, but problems such as fiber clogging may occur, requiring regular cleaning and maintenance.

[0029] The sealing cover 2 and the separation tank 1 are both fixedly connected to one side of the mounting block, and the top of the mounting block is threaded with a fixing bolt extending to its bottom.

[0030] In this embodiment, an inlet pipe 12 extending into the interior is fixedly connected to one side of the separation tank 1, an outlet pipe 13 communicating with the separation tank 1 is fixedly connected to the top of the sealing cover plate 2, a drain pipe 14 communicating with the interior is fixedly connected to the bottom of the separation tank 1, and a valve is fixedly installed on the outside of the drain pipe 14.

[0031] The working principle of the above embodiments is as follows:

[0032] First, connect the delivery pipe to the liquid inlet pipe 12, and then deliver the gas and liquid into the separation tank 1. At this time, start the drive motor 3 to drive the stirring blades 7 to rotate slowly and stir the liquid. The gas will flow upward and first come into contact with the inclined plate 8 to remove some water droplets from the gas. Then, it passes through the demister 11 to completely separate the water droplets from the gas. Finally, it is discharged through the gas outlet pipe 13.

[0033] All electrical components mentioned in this article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions. Furthermore, the existing publicly available power connection technology is common knowledge in this field and will not be elaborated upon in this article.
