DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3 This embodiment provides an automatic mud discharge three-phase separator, and the automatic mud discharge three-phase separator comprises:

[0022] A three-phase separator 2, wherein a feed pipe 3 is provided at one end of the three-phase separator 2, an air outlet 4 is provided at the top end of the three-phase separator 2, an oil outlet 5 and a drain outlet 6 are provided at the bottom end of the three-phase separator 2, a baffle 8 is provided at one end of the feed pipe 3 inside the three-phase separator 2, a plurality of wave-breaking plates 11 are provided at the bottom end of the three-phase separator 2, an overflow partition 18 is provided at one end of the wave-breaking plate 11 located at the oil outlet 5, a rectifier 9 and a mist collector 10 are provided at the top end of the wave-breaking plate 11 inside the three-phase separator 2, a downflow pipe 12 is provided at one end of the mist collector 10, and a decontamination structure is provided at one end of the wave-breaking plate 11 inside the three-phase separator 2;

[0023] Compared with the prior art, by setting a decontamination structure inside the three-phase separator 2, the residual impurities inside the three-phase separator 2 can be processed to avoid long-term accumulation of impurities inside the three-phase separator 2, which not only reduces the separation effect of oil, gas and water, but also causes corrosion inside the three-phase separator 2, thereby reducing the service life of the three-phase separator 2.

[0024] See also Figure 2 The three-phase separator 2 is provided with vortex preventers 13 at the oil outlet 5 and the drain outlet 6;

[0025] The oil-gas-water mixture enters the three-phase separator 2 through the feed pipe 3, and then enters the separator body, where it is pre-separated. Most of the oil and a small amount of natural gas float to the upper part of the cylinder to form an oil cavity, while water sinks to the bottom to form a water cavity. The oil, gas and water are further separated under the action of the overflow baffle 18, and the oil and water are discharged from the oil outlet 5 and the drain outlet 6 respectively, while the natural gas is discharged from the gas outlet 4 of the three-phase separator 2. This separation method is based on the oil-gas-water mixture entering the separator body through the inlet and outlet pipes, and utilizing their different physical properties in the cylinder (such as density, Viscosity, etc.) is used to separate the oil, gas and water mixture. In the process of separating the oil, gas and water mixture, the baffle 8 is provided to enable the liquid substance to sink quickly, and the rectifier 9 can realize the conversion between AC and DC. By providing a mist collector 10 at one end of the gas outlet 4, the liquid oil remaining in the gas can be further separated and finally flow into the downflow pipe 12. By providing a vortex preventer 13 at the oil outlet 5 and the drain outlet 6, the vortex can be avoided at this position, making the oil-water separation more stable. In addition, the wave-breaking plate 11 can further stabilize the oil-water interface, which is helpful for the separation of oil and water.

[0026] See also Figure 2-Figure 3 , see Figure 1-Figure 3 In one embodiment, the decontamination structure comprises:

[0027] An installation shaft 14, wherein the installation shaft 14 is rotatably connected to the inside of the three-phase separator 2, and one end of the installation shaft 14 located inside the three-phase separator 2 is fixedly connected to a transmission wheel 15, and the two transmission wheels 15 are connected to each other through a transmission chain 16;

[0028] A scraper 17, wherein the scraper 17 is fixedly mounted on the outside of the transmission chain 16 and is slidably matched with the bottom end of the inner wall of the three-phase separator 2;

[0029] See also Figure 1-Figure 2 Flanges are provided at the connection positions of the feed pipe 3, the air outlet 4, the oil outlet 5 and the three-phase separator 2, which can improve the sealing performance at the feed pipe 3, the air outlet 4, the oil outlet 5.

[0030] See also Figure 1 A support frame 1 is disposed at the bottom end of the three-phase separator 2, and a support base 7 is symmetrically disposed at the bottom end of the support frame 1, so that the three-phase separator 2 can be stably placed on the ground.

[0031] As the three-phase separator 2 is used for a long time, impurities will accumulate at its bottom. At this time, by controlling one of the installation shafts 14 inside the three-phase separator 2 to rotate, the installation shaft 14 then drives the transmission wheel 15 to rotate. Since the two transmission wheels 15 are connected by a transmission chain 16, the transmission chain 16 can be driven to rotate, and the transmission chain 16 then drives the scraper 17 to rotate accordingly. By forming a sliding fit between the scraper 17 and the bottom inner wall of the three-phase separator 2, the impurities accumulated on the inner wall of the three-phase separator 2 can be removed and discharged from the drain port 6.

[0032] The working principle of the utility model is:

[0033] In this embodiment, the oil-gas-water mixture enters the three-phase separator 2 through the feed pipe 3, and then enters the separator body, and is pre-separated in the cylinder. Most of the oil and a small amount of natural gas will float to the upper part of the cylinder to form an oil cavity, while the water will sink to the bottom to form a water cavity. The oil, gas and water are further separated under the action of the overflow baffle 18, and the oil and water are discharged from the oil outlet 5 and the drain port 6 respectively, while the natural gas is discharged from the gas outlet 4 of the three-phase separator 2. This separation method is based on the oil-gas-water mixture entering the separator body through the inlet and outlet pipes, and using their different physical properties (such as density, viscosity, etc.) in the cylinder to achieve separation. In the process of separating the oil-gas-water mixture, the baffle 8 is set to enable the liquid substance to sink quickly, and the rectifier 9 can realize the conversion between AC and DC, and the mist collector 10 is set at one end of the gas outlet 4. The liquid oil remaining in the gas can be further separated and finally flow into the downflow pipe 12. By setting the vortex preventer 13 at the oil outlet 5 and the drain outlet 6, the vortex can be avoided at this position, making the oil-water separation more stable. The wave-breaking plate 11 can further make the oil-water interface more stable, which is helpful for the separation of oil and water. As the three-phase separator 2 is used for a long time, impurities will accumulate at its bottom. At this time, by controlling one of the mounting shafts 14 inside the three-phase separator 2 to rotate, the mounting shaft 14 drives the transmission wheel 15 to rotate. Since the two transmission wheels 15 are connected by the transmission chain 16, the transmission chain 16 can be driven to rotate, and the transmission chain 16 drives the scraper 17 to rotate accordingly. By forming a sliding fit between the scraper 17 and the bottom inner wall of the three-phase separator 2, the impurities accumulated on the inner wall of the three-phase separator 2 can be removed and the impurities can be discharged from the drain outlet 6.
