Description

Technical Field

[0001] The utility model relates to the technical field of three-phase separator devices, and particularly relates to an oil-gas-water three-phase separator device. Background Art

[0002] The oil-gas-water three-phase separator is one of the most commonly used devices in the oilfield development and production process. The crude oil collected from the oilfield contains many impurities and cannot be directly used. Therefore, the oil-gas-water three-phase separator is usually used to separate oil, gas and water first. The oil-gas-water three-phase separator and the processing system composed of it play an important role in crude oil and natural gas production.

[0003] However, when the existing three-phase separator device is in use, due to the different densities of different substances in the oil-gas-water mixture, the existing three-phase separator device generally inputs the oil-gas-water mixture into the three-phase separator device first, and after the substances inside it are gradually precipitated and separated, it is convenient to discharge oil, gas and water respectively. This separation method is extremely time-consuming and laborious, resulting in low separation efficiency of the three-phase separator device.

[0004] Therefore, it is very necessary for us to propose an oil-gas-water three-phase separator device to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an oil-gas-water three-phase separator device. Through the mutual cooperation between the stirring mechanism inside the three-phase separator main body and the parts inside the separation mechanism, the separation efficiency of the three-phase separator main body for the oil-gas-water mixture can be improved, so as to solve the problem that in the prior art, the existing three-phase separator device generally inputs the oil-gas-water mixture into the three-phase separator device first, and after the substances inside it are gradually precipitated and separated, it is convenient to discharge oil, gas and water respectively. This separation method is extremely time-consuming and laborious, resulting in low separation efficiency of the three-phase separator device.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution: an oil-gas-water three-phase separator device, including a three-phase separator main body, one side of the three-phase separator main body is fixedly connected with a water inlet pipe, and penetrates into the inside of the three-phase separator main body. The top end of the three-phase separator main body is fixedly connected with a separation mechanism, and penetrates into the inside of the three-phase separator main body. One side of the separation mechanism close to the water inlet pipe is fixedly connected with a stirring mechanism, and is located inside the three-phase separator main body.

[0007] Preferably, the separation mechanism includes an exhaust pipe which is fixedly connected to the top end of the three-phase separator main body and penetrates into the interior of the three-phase separator main body. A drain pipe is fixedly connected to the bottom end of the three-phase separator main body. A sewage discharge pipe is fixedly connected to one side of the drain pipe and is located at the bottom end of the three-phase separator main body. An oil discharge pipe is fixedly connected to the side of the sewage discharge pipe far away from the drain pipe and penetrates into the interior of the three-phase separator main body. A sealing partition is fixedly connected to the interior of the three-phase separator main body and is located on the side where the water inlet pipe penetrates into the interior of the three-phase separator main body. A flow retardation plate is installed on the side of the sealing partition close to the drain pipe and is fixedly connected to the interior of the three-phase separator main body. A first separation chamber is arranged between the sealing partition and the inner wall of the three-phase separator main body. A second separation chamber is arranged between the sealing partition and the flow retardation plate. A sedimentation chamber is arranged between the side of the flow retardation plate far away from the sealing partition and the inner wall of the three-phase separator main body.

[0008] Preferably, the stirring mechanism includes a fixing plate which is fixedly connected to the side of the sealing partition close to the water inlet pipe. A connecting rod is rotatably connected to the bottom end of the fixing plate. Stirring blades are fixedly sleeved on the outer wall of the bottom end of the connecting rod. A plurality of connecting columns are fixedly connected to the outer wall of the connecting rod and are located above the stirring blades. The side of the connecting column far away from the connecting rod is fixedly connected to a transmission blade and is located at the bottom end of the water inlet pipe.

[0009] Preferably, connection grooves matching the drain pipe and the sewage discharge pipe are formed in the interior of the three-phase separator main body. An exhaust hole matching the exhaust pipe is formed in the top end of the three-phase separator main body. An oil discharge port matching the oil discharge pipe is formed in the bottom end of the three-phase separator main body.

[0010] Preferably, water inlet grooves are formed at the joints where the two ends of the sealing partition are in contact with the inner wall of the three-phase separator main body and are respectively connected to the first separation chamber and the second separation chamber. Flow retardation grooves connected to the sedimentation chamber are formed on the surface of the flow retardation plate.

[0011] Preferably, the connecting rod is rotatably connected to the fixing plate through a ball.

[0013] 1. Through the water inlet pipe, the water inlet pipe pours the oil-gas-water mixture into the first separation chamber inside the three-phase separator body. The oil-gas-water mixture is diverted through the water inlet grooves at both ends of the sealing partition on one side of the first separation chamber into the second separation chamber. At the same time, when the diverted oil-gas-water mixture flows into the second separation chamber, the diverted oil-gas-water mixture collides with each other inside the second separation chamber, and the water flow forms a vortex, so that the oil, gas and water are separated from each other. At the same time, the gas is discharged from the inside of the three-phase separator body through the exhaust pipe. At the same time, after the oil and water collide with each other, they flow into the sedimentation chamber through the flow retarder plate, and the collided and mixed oil and water are retarded by the flow retarder plate and flow into the sedimentation chamber for sedimentation separation, and the separation operation of the oil, gas and water can be completed;

[0014] 2. The oil-gas-water mixture is transported to the inside of the three-phase separator body through the water inlet pipe. When the water flow drops from the water inlet pipe, it impacts the drive blades. The drive blades are driven to rotate by the force. The drive blades drive the connecting rod at the bottom end of the fixed plate to rotate through the connecting column. The rotation of the connecting rod drives the stirring blades sleeved on the outer wall of the bottom end to rotate. The rotation of the stirring blades drives the oil-gas-water mixture inside the first separation chamber to rotate. The rotation of the oil-gas-water mixture separates the oil, gas and water from each other by centrifugal force, and the oil is separated and floats on the water surface. After the oil-gas-water mixture is separated by stirring and then flows into the second separation chamber, the separation efficiency of the three-phase separator body can be improved.
