Description

Technical Field

[0001] The invention relates to the technical field of crude oil separation, and in particular to a sulfur-proof oil, gas and water three-phase separator. Background Art

[0002] The oil, gas and water three-phase separator is one of the commonly used equipment in the oil field development and production process. It is mainly used to separate the three different components of crude oil, natural gas and water. Among them, the sulfur-resistant oil, gas and water three-phase separator is a specially designed oil, gas and water three-phase separation equipment. Its main feature is the ability to resist sulfur corrosion. This is usually achieved by using special corrosion-resistant materials or coatings inside the equipment. The working principle of the sulfur-resistant oil, gas and water three-phase separator is based on the density and relative motion characteristics of different components. When the oil, gas and water mixture enters the separator, the mixed fluid is separated into crude oil, natural gas and water by changing the direction and speed of the liquid flow, stabilizing the fluid state and accelerating the focusing of water droplets, etc., using centrifugal force, buoyancy and gravity.

[0003] After searching, the invention patent with Chinese patent number CN114931795A discloses an oil-gas-water three-phase separator for offshore oil production that is easy to remove impurities. Compared with the existing technology, the invention patent with Chinese patent number CN114931795A enables the three-phase separator to have the function of separating impurities in crude oil, and at the same time has the function of cleaning impurities, which can maximize the recovery of crude oil.

[0004] In actual use, the above-mentioned device is used to separate impurities from the extracted crude oil for offshore oil production. However, since the impurities in marine crude oil include mud, stones, metal fragments, etc., these impurities have different shapes, sizes and densities. When filtering and separating through the separation net, they are easy to adhere to the separation net, forming sediments that are difficult to remove, thereby causing the separation net to be blocked, resulting in interruption of the filtration process. The surface of the filtered impurities still contains crude oil. Directly processing the impurities after filtering them out reduces the utilization rate of the crude oil. Therefore, a sulfur-proof oil, gas and water three-phase separator is proposed. Summary of the invention

By starting the servo motor 7, the threaded rod 6 can be driven to rotate back and forth, and the force generated when the threaded rod 6 rotates can drive the movable plate 5 to move up and down.

[0037] The size of the opening of the control box 4 is matched with the size of the movable plate 5 to ensure the stability of the movable plate 5 when it moves up and down.

[0038] A plurality of open grooves 12 are provided on one side of the movable rod 11 close to the first filter screen 3, and a first spring 13 is installed on the inner side of the open groove 12. One end of the first spring 13 close to the first filter screen 3 is fixedly connected to a processing block 14. The processing block 14 moves into the through hole of the first filter screen 3 to squeeze out impurities in the through hole of the first filter screen 3.

[0039] The size of the opening of the opening slot 12 is adapted to the size of the processing block 14. The cross section of the processing block 14 is an isosceles trapezoid. The inclined surface of the processing block 14 squeezes the edge of the through hole of the first filter screen 3 to expand and contract.

[0040] A square groove 15 is opened on the inner side of the processing box 2, and a movable block 28 is slidably set on the inner side of the square groove 15. A square plate 17 is installed on the inner side of the collecting box 16. A round rod 18 is installed on the side of the movable block 28 away from the movable rod 11, and the round rod 18 and the square plate 17 are movably connected. A second spring 19 is installed on the side of the movable block 28 away from the movable rod 11, and the side of the second spring 19 away from the movable block 28 is fixedly connected to the square plate 17. When the scraper 10 moves downward, it can squeeze the movable block 28 and squeeze the movable block 28 to the outside of the square groove 15.

[0041] An inclined block 27 is installed inside the processing box 2 . The cross section of the inclined block 27 is triangular, and the impurities can be guided to the movable block 28 through the inclined surface of the inclined block 27 .

[0042] In this embodiment, when the crude oil is subjected to oil-gas-water separation, the crude oil first enters the processing box 2, is filtered through the first filter screen 3, and the solid impurities in the crude oil are filtered out, and then the crude oil is continuously discharged into the inner side of the oil-gas-water three-phase separator 1 through the L-shaped rod 25 for oil-gas-water separation. When the crude oil is filtered through the first filter screen 3, the servo motor 7 can be started at this time, and the threaded rod 6 can be driven to rotate back and forth by the servo motor 7. The force generated when the threaded rod 6 rotates can drive the movable plate 5 to move up and down. When the movable plate 5 moves up and down, it can drive the first connecting rod 8 and the second connecting rod 9 to move up and down, thereby driving the scraper 10 and the movable rod 11 to move up and down. When the movable rod 11 moves, it can drive the processing block 14 to move. When the processing block 14 moves to the through hole of the first filter screen 3, the processing block 14 is no longer Supported by the first filter screen 3, the first spring 13 in the contracted state is reset, and then the processing block 14 is driven to move into the through hole of the first filter screen 3. When the movable rod 11 continues to move downward, the inclined surface of the processing block 14 squeezes the edge of the through hole of the first filter screen 3, and then drives the first spring 13 to contract, and at the same time makes the processing block 14 retract into the inner side of the opening groove 12, and no longer inserts into the through hole of the first filter screen 3, thereby driving the processing block 14 to no longer insert into the through hole of the first filter screen 3 through the up and down movement of the movable rod 11, thereby squeezing out the impurities accumulated in the through hole of the first filter screen 3, thereby removing the solid impurities in the crude oil, helping to reduce the pollutants in the crude oil, improving the quality and purity of the crude oil, and avoiding a large amount of impurities from clogging the separation structure inside the oil-gas-water three-phase separator 1, affecting the separation work;

[0043] When the scraper 10 moves up and down, the impurities adsorbed on the surface of the first filter screen 3 and the impurities squeezed out by the movable rod 11 can be scraped off by the scraper 10, and then the impurities are moved to the inclined surface of the movable block 28 through the guidance of the inclined surface of the inclined block 27. When the scraper 10 moves down, the movable block 28 can be squeezed to the outside of the square groove 15. At this time, the second spring 19 contracts, and then the impurities on the inclined surface of the movable block 28 fall into the collection box 16, and the scraper 10 is moved into the square groove 15 at the same time. When the scraper 10 moves up and no longer squeezes the movable block 28, the second spring 19 is reset, and then drives the movable block 28 to reset, so that the movable block 28 moves back to the inside of the square groove 15, so that the square groove 15 always remains in a sealed state, thereby moving the impurities to the outside of the processing box 2 in real time, and ensuring that the filtering process will not be interrupted due to the accumulation of impurities.

[0044] Embodiment 2

[0045] like Figure 1- Fig. 9 As shown, based on the first embodiment, an L-shaped rod 25 is installed on the upper part of the rack 24, and one end of the L-shaped rod 25 away from the rack 24 is fixedly connected to the movable block 28, the rack 24 is meshed with the second gear 23, and the second gear 23 is meshed with the first gear 20, and the second filter screen 21 is driven to rotate back and forth, thereby shaking the impurities and crude oil on the second filter screen 21.

[0046] The inner side of the collecting box 16 is symmetrically mounted with an arc block 22, which is in contact with the second filter screen 21, ensuring that the second filter screen 21 is always in contact with the arc block 22 when rotating, thereby preventing impurities from falling.

[0047] The size of the opening of the square groove 15 is matched with the size of the movable block 28 and the scraper 10, so that the square groove 15 is always kept in a sealed state.

[0048] In this embodiment, when the impurities are discharged into the collection box 16, they fall on the second filter screen 21, and then the crude oil adsorbed on the impurities falls due to the action of gravity, and then falls to the bottom of the collection box 16 through the through hole of the second filter screen 21. At the same time, when the movable block 28 moves up and down, the rack 24 can be driven to move by the L-shaped rod 25. When the rack 24 moves up and down, the first gear 20 can be driven to rotate slightly back and forth through the second gear 23, thereby driving the second filter screen 21 to rotate back and forth, and then the impurities and crude oil on the second filter screen 21 are shaken, so that the crude oil is easier to separate from the impurities, and then falls on the inside of the collection box 16, so as to further separate the crude oil from the impurities, which can maximize the utilization rate of the crude oil.
