Description

Technical Field

[0001] This utility model relates to the field of oil-gas-water separation technology, and in particular to a novel three-phase oil-gas-water separation device. Background Technology

[0002] The new type of oil-gas-water three-phase separation device is a widely used equipment in the oilfield development and production process. It is mainly used to effectively separate and process the mixed liquid produced by oil wells, including crude oil, natural gas and water.

[0003] For example, the existing oil-gas-water three-phase separation device with publication number CN109652113A specifically discloses a horizontally placed tank. An inlet for the mixed oil, gas, and water is opened at the top near the first end of the tank. An oil weir plate and a water weir plate are sequentially arranged at the bottom of the tank from the first end to the second end. The oil weir plate and water weir plate sequentially divide the interior of the tank from the first end to the second end into a mixed oil-gas-water chamber, an oil chamber, and a water chamber. An oil outlet is opened at the bottom of the oil chamber, and a water outlet is opened at the bottom of the water chamber. An air outlet is opened at the top near the second end of the tank. An internal connecting pipe connects the mixed oil-gas-water chamber and the water chamber. A liquid level detection component and a density detection device are provided in both the oil chamber and the water chamber.

[0004] In existing oil-gas-water three-phase separation devices, a significant amount of water is mixed in the gas phase during the gas phase separation process. This water dilutes oil and other impurities, reducing the separation efficiency and failing to achieve the intended purpose of removing oil and protecting the equipment. Excessive water may also affect the flowability and stability of the gas phase, further impacting the separation effect. Therefore, we propose a novel oil-gas-water three-phase separation device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a novel three-phase oil-gas-water separation device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel oil-gas-water three-phase separation device, comprising: a tank body, wherein support columns are fixedly installed at the four corners of the bottom of the tank body, a feed pipe is connected to and fixedly installed at one end of the tank body, and a drain pipe is connected to and fixedly installed at the bottom of the tank body;

[0007] A splined tube is connected to and fixedly installed at the top of the tank. A splined groove is provided on the inner side of the splined tube. The lower end of the splined tube extends into the tank body. A movable tube is inserted into the splined tube. A spline is provided on the outer side of the movable tube. The movable tube and the splined tube are splinedly engaged. The movable tube can slide along the splined tube. An exhaust hole is opened at the top of the tank body. An annular seat is provided at the upper end of the tank body. Multiple grooves are opened on the annular seat in a circumferential array. A channel is opened at the bottom of the annular seat. The channel communicates with the multiple grooves. The exhaust hole and the channel are connected by a connecting pipe. The upper end of the connecting pipe is fixed to the annular seat and the lower end is rotatably installed on the tank body. Water-absorbing cotton is provided in each groove. A sealing plate is provided on the annular seat. An exhaust pipe is fixedly installed on the sealing plate. The exhaust pipe is connected to an external exhaust pipe.

[0008] As a further technical solution of this utility model, a transparent observation window is provided on the tank body, and a material level scale line is provided on the tank body.

[0009] As a further technical solution of this utility model, a drive shaft is fixedly installed at the bottom of each absorbent cotton, and the drive shaft passes through the annular seat.

[0010] As a further technical solution of this utility model, the bottom of the transmission shaft is provided with anti-slip texture, a motor is fixedly installed on the tank body, a drive wheel is fixedly installed on the output shaft end of the motor, and the drive wheel and the transmission shaft are transmitted through friction.

[0012] As a further technical solution of this utility model, a baffle is fixedly installed inside the tank.

[0013] This utility model provides a novel three-phase oil-gas-water separation device, which has the following advantages compared with the prior art:

[0014] 1. This design presents a novel three-phase oil-gas-water separation device. Gas inside the tank is discharged through an exhaust port, while the gas enters the channel through a connecting pipe and is then dried by absorbent cotton in a groove. This drying process significantly reduces the moisture content in the gas phase, resulting in a purer gas phase. This helps improve the overall efficiency of the three-phase oil-gas-water separation, making the separation of crude oil, natural gas, and water more thorough, thereby improving product quality and production efficiency.

[0015] 2. This design presents a novel three-phase oil-gas-water separation device. By rotating absorbent cotton and uniformly absorbing moisture from the gas, the utilization rate of the absorbent cotton is improved. By rotating the annular seat, different absorbent cottons within the seat absorb moisture, allowing for the switching of different absorbent cottons for use. When the moisture content of the absorbent cotton becomes high, a dry absorbent cotton is promptly switched on, thus maintaining a high degree of dryness in the separated gas.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a novel three-phase oil-gas-water separation device: a novel three-phase oil-gas-water separation device, comprising: a tank body 1, with support columns 2 fixedly installed at the four corners of the bottom of the tank body 1, a feed pipe 3 connected to and fixedly installed at one end of the tank body 1, a valve installed on the feed pipe 3, and a drain pipe 4 connected to and fixedly installed at the bottom of the tank body 1. A splined tube 5 is connected to and fixedly installed at the top of the tank body 1. A splined groove is provided on the inner side of the splined tube 5. The lower end of the splined tube 5 extends into the tank body 1. A movable tube 6 is inserted into the splined tube 5. A spline 7 is provided on the outer side of the movable tube 6. The movable tube 6 and the splined tube 5 are splined together. The movable tube 6 can slide along the splined tube 5. An exhaust hole 8 is opened at the top of the tank body 1. An annular seat 9 is provided at the upper end of the tank body 1. Multiple grooves 10 are provided on the annular seat 9 in a circular array. A channel 11 is opened at the bottom of the annular seat 9. The channel 11 is connected to the multiple grooves 10. The exhaust hole 8 and the channel 11 are connected by a connecting pipe 12. The upper end of the connecting pipe 12 is fixedly connected to the annular seat 9 and the lower end is rotatably installed on the tank body 1. Water-absorbing cotton 13 is provided in each groove 10. A sealing plate 14 is provided on the annular seat 9. An exhaust pipe 15 is fixedly installed on the sealing plate 14. The exhaust pipe 15 is connected to an external exhaust pipe. Tank 1 is equipped with a transparent observation window and a material level scale. Gas inside tank 1 is discharged through the vent 8 and enters the channel 11 through the connecting pipe 12. It is then dried by the absorbent cotton 13 in the groove 10. This drying process significantly reduces the moisture content in the gas phase, making it purer. This helps improve the overall efficiency of oil-gas-water three-phase separation, resulting in more thorough separation of crude oil, natural gas, and water, thereby improving product quality and production efficiency.

[0023] Among them, such as Figure 3 and Figure 4 As shown, a drive shaft 16 is fixedly installed at the bottom of the absorbent cotton 13, and the drive shaft 16 passes through the annular seat 9. The bottom of the drive shaft 16 is provided with anti-slip texture. A motor 17 is fixedly installed on the tank body 1, and a drive wheel 18 is fixedly installed at the output shaft end of the motor 17. The drive wheel 18 and the drive shaft 16 are transmitted through friction. A floating block 19 is fixedly installed at the bottom of the movable pipe 6. A baffle 20 is fixedly installed inside the tank body 1. The mixture enters the tank body 1 through the feed pipe 3. After the mixture in the tank body 1 settles, it will separate into layers, with the upper layer being oil and the lower layer being water. The lower layer of water is discharged through the drain pipe 4. The lower end of the movable pipe 6 extends into the upper layer of oil. The movable pipe 6 is connected to a suction pump, which sucks out the oil from the lower end of the movable pipe 6. The floating block 19 floats in the water, and the lower end of the movable pipe 6 can remain immersed in the oil. By setting the baffle 20 to block the mixture, it is possible to prevent the mixture from impacting the oil and water in the tank body 1 and to prevent the oil-water separation state from being disrupted.

[0024] The working principle of this invention is as follows: The mixture enters the tank 1 through the feed pipe 3. After standing, the mixture in the tank 1 will separate into layers, with the upper layer being oil and the lower layer being water. The lower water layer is discharged through the drain pipe 4. The lower end of the movable pipe 6 extends into the upper oil layer. The movable pipe 6 is connected to a suction pump, which draws the oil out through the lower end of the movable pipe 6. The floating block 19 floats in the water, and the lower end of the movable pipe 6 remains immersed in the oil. The gas in the tank 1 is discharged through the exhaust port 8 and enters the channel 11 through the connecting pipe 12. Then, it is dried by the absorbent cotton 13 in the groove 10. Through drying, the water content in the gas phase can be significantly reduced, making the gas phase purer. This helps to improve the overall efficiency of the three-phase separation of oil, gas, and water, making the separation of crude oil, natural gas, and water more thorough, thereby improving product quality and production efficiency. The motor 17 drives the drive wheel 18 to rotate, which in turn drives the transmission shaft 16 to rotate. This causes the absorbent cotton 13 to rotate and evenly absorb moisture from the gas, thus improving the utilization rate of the absorbent cotton 13. By rotating the annular seat 9, different absorbent cotton 13s within the seat absorb moisture, allowing for the switching of different absorbent cotton 13s for use. When the moisture content of the absorbent cotton 13 becomes high, a dry absorbent cotton 13 is promptly switched to maintain a high degree of dryness in the separated gas.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
