Description

Technical Field

[0001] The present invention belongs to the technical field of oil-gas-water separation, and particularly relates to an industrial three-phase separator capable of filtering oil, gas and water. 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. Its working principle is to utilize the gravity sedimentation effect, so that the gas in the oil-gas-water mixture is discharged from the exhaust port at the top of the three-phase separator, and the oil floats on the water surface and overflows through the overflow baffle. However, during the oil extraction process, the oil-gas-water mixture will be mixed with impurities such as sand and rock slag. These impurities are deposited at the bottom of the three-phase separator tank and are difficult to clean, and it is easy to cause blockage of the drain pipe.

[0003] However, the existing three-phase separators do not have a filtering function, and a filtering device needs to be installed at the liquid inlet. Cleaning and maintaining the filtering device will increase the production cost. Moreover, the existing three-phase separators cannot observe the liquid level height inside the tank from the outside. When the proportion of water in the mixture is relatively large, it is easy to cause the water in the tank to overflow over the overflow baffle, resulting in the mixing of the separated oil and water again. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art, and a proposed industrial three-phase separator capable of filtering oil, gas and water is provided.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An industrial three-phase separator capable of filtering oil, gas and water, including a tank body. An air-liquid separation chamber, a filtering chamber, an oil-water stratification chamber and an oil collection chamber are arranged in the tank body. A liquid inlet and an exhaust port are arranged at the top of the air-liquid separation chamber. The air-liquid separation chamber is located above the filtering chamber.

The filtering chamber is located above the oil-water stratification chamber, and the filtering chamber is communicated with the oil-water stratification chamber. A reflux slope is arranged at the bottom of the filtering chamber, and the reflux slope extends above the oil-water stratification chamber. A plurality of linearly distributed anti-wave plates are welded to the inner wall bottom of the oil-water stratification chamber. A plurality of through holes are arranged on the outer wall of each anti-wave plate.

An oil drain port is arranged at the inner wall bottom of the oil collection chamber. A filtering mechanism is arranged in the filtering chamber, and a prompting mechanism is arranged in the oil-water stratification chamber.

[0007] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, a sealing door is rotatably connected to the end of the filtering chamber through a hinge. An oil discharge hole is opened at the bottom of the outer wall of the overflow partition plate. A sealing disk is rotatably inserted into the overflow partition plate. A pair of symmetric docking holes are opened on the outer wall of the sealing disk, and each docking hole is adapted to the oil discharge hole. An operating rod is welded to the outer wall of the sealing disk on the side away from the wave-proof plate. The operating rod extends to the outside of the tank body, and a cross handle is welded to the end of the operating rod away from the sealing disk.

[0008] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, the filtering mechanism includes an inlet baffle, a collection frame and a holder. A chute one and a mounting groove are opened on the inner wall of the filtering chamber. The chute one is an inclined chute, and the inclination direction of the chute one is opposite to the inclination direction of the reflux inclined plane. A chute two is opened on the inner wall of the filtering chamber. The chute two is parallel to the chute one, and the chute two extends into the mounting groove. An inlet baffle is rotatably inserted into the inner wall of the gas-liquid separation chamber. The inlet baffle is located obliquely below the liquid inlet. A driving wheel is welded to the outer wall of one side of the inlet baffle. The driving wheel is rotatably inserted into the outer wall of the tank body. A driven wheel is rotatably inserted into the outer wall of the tank body. A transmission belt is sleeved on the outer walls of the driven wheel and the driving wheel.

[0009] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, a transmission wheel is welded to the outer wall of the driven wheel on the side close to the filtering chamber. The transmission wheel is rotatably inserted into the mounting groove. A clamping groove is opened on the outer wall of the transmission wheel on the side away from the driven wheel. A handle is welded to the outer wall of the driven wheel on the side away from the filtering chamber. The handle is parallel to the clamping groove.

[0010] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, the collection frame is slidably inserted into the filtering chamber. A sliding column is welded to the outer wall of the end of the collection frame. The sliding column is slidably inserted into the chute one. The bottom of the outer wall of the end of the collection frame away from the sliding column abuts against the reflux inclined plane. A water baffle is welded to the bottom of the inner wall of the collection frame. Filtering holes are opened at the bottom of the inner wall of the collection frame.

[0011] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, a holder is rotatably inserted into the inner wall of the collection frame on the side close to the sliding column. The holder is located obliquely below the downstream port. A corrugated filter screen is adhered to the outer wall of the holder. A clamping block is welded to the rotating shaft of the holder. The clamping block is adapted to the clamping groove. The clamping block is adapted to the chute two.

[0012] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, the prompting mechanism includes a benchmark. The benchmark is slidably inserted into the top inner wall of the oil-water separation chamber. The benchmark is coaxially distributed with the drain port. The benchmark extends to the outside of the tank body. A floating block is bonded to the bottom end of the benchmark. The floating block is adapted to the drain port. Scale lines are printed on the outer wall of the top end of the benchmark.

[0013] In the above-mentioned industrial three-phase separator capable of filtering oil, gas and water, the top end of the benchmark is connected to a connecting rod through a rotating shaft. The end of the connecting rod away from the benchmark is rotatably connected to a sealing plate through a rotating shaft. The sealing plate is slidably inserted into the top inner wall of the gas-liquid separation chamber. The sealing plate is adapted to the liquid inlet.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By setting the filtering mechanism, when the mixed liquid enters the gas-liquid separation chamber through the liquid inlet, the mixed liquid impacts on the inlet baffle obliquely below the liquid inlet, and the liquid column of the mixed liquid is dispersed, so as to release the gas wrapped in the mixed liquid and buffer the mixed liquid at the same time. The mixed liquid falls to the bottom of the gas-liquid separation chamber and then flows into the filtering chamber through the downstream port. The inlet baffle rotates under the action of the impact force of the mixed liquid, so that the inlet baffle drives the driving wheel to rotate. Under the action of the transmission belt, the driven wheel rotates, so that the driven wheel drives the transmission wheel to rotate, and thus the transmission wheel drives the clamping groove to rotate. Under the cooperation of the clamping groove and the clamping block, the clamping block rotates along with the clamping groove, and then the clamping block drives the cage to rotate, and the cage drives the filter screen to rotate, so as to filter the mixed liquid flowing out of the downstream port. During the rotation of the filter screen, the impurities intercepted by the filter screen are poured into the collection frame and collected. The mixed liquid sputtered in the collection frame will fall through the water filter holes at the bottom of the collection frame onto the reflux inclined plane and finally flow into the oil-water separation chamber along the reflux inclined plane. When the filtering mechanism needs to be cleaned and maintained, open the sealing door, rotate the handle, rotate the clamping groove to be flush with the chute two, so that the clamping block can slide into the chute two from the clamping groove, and pull out the collection frame from the filtering chamber. When the sliding column slides to the end of the chute one, the collection frame loses the abutting effect of the reflux inclined plane and flips downward, so as to pour out the impurities in the collection frame. The collection frame drives the cage to slide out of the filtering chamber together, which is convenient for cleaning and maintaining the filter screen on the cage;

[0016] 2. By setting the prompting mechanism, when the mixed liquid enters the oil-water separation chamber, the water in the mixed liquid can drive the floating block to float, so that the floating block can drive the benchmark to rise. By observing the scale line on the benchmark, the water surface height in the oil-water separation chamber can be known. When the water surface height in the oil-water separation chamber is too high, the benchmark drives the connecting rod to swing, so that the connecting rod drives the sealing plate to slide towards the liquid inlet, so that the sealing plate closes the liquid inlet, preventing the mixed liquid from entering, and thus preventing the water surface height in the oil-water separation chamber from rising further;

[0017] In summary, through the provided filtering mechanism, impurities in the mixed liquid can be filtered, and the filtered impurities are collected by the collection box, preventing the impurities from depositing at the bottom of the tank body of the three-phase separator. The collection box can drive the cage to slide out of the filtration chamber together, facilitating the cleaning and maintenance of the filter screen on the collection box and the cage. By setting up the prompting mechanism, the outside can know the water level height in the oil-water separation chamber by observing the scale line on the observation rod, thus prompting the outside to take corresponding measures in a timely manner to prevent the water in the tank from overflowing over the overflow partition.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] Please refer to Figures 1-9, the present invention provides a technical solution: including a tank body 1, in which a gas-liquid separation chamber 11, a filtration chamber 12, an oil-water separation chamber 13 and an oil collection chamber 14 are provided. At the top of the gas-liquid separation chamber 11, a liquid inlet 111 and an exhaust port 112 are provided. The gas-liquid separation chamber 11 is located above the filtration chamber 12. At the bottom of the gas-liquid separation chamber 11, a downward flow port 113 is provided, and the downward flow port 113 communicates with the filtration chamber 12. The filtration chamber 12 is located above the oil-water separation chamber 13, and the filtration chamber 12 communicates with the oil-water separation chamber 13. At the bottom of the filtration chamber 12, a reflux slope 123 is provided, and the reflux slope 123 extends above the oil-water separation chamber 13. At the bottom inner wall of the oil-water separation chamber 13, several linearly distributed anti-wave plates 132 are welded. On the outer wall of each anti-wave plate 132, several through holes 133 are provided. At the transition between the oil-water separation chamber 13 and the oil collection chamber 14, an overflow partition plate 142 is welded. At the bottom inner wall of the oil-water separation chamber 13 near the overflow partition plate 142, a drain port 131 is provided. At the bottom inner wall of the oil collection chamber 14, an oil drain port 141 is provided. A filtration mechanism is provided in the filtration chamber 12, and a prompting mechanism is provided in the oil-water separation chamber 13.

[0031] At the bottom end of the exhaust port 112, a mist eliminator is installed, which can collect the oil-water mixture carried in the gas. At the bottom of the mist eliminator, a downward flow pipe is installed, and the downward flow pipe extends above the downward flow port 113. The oil-water mixture recovered by the mist eliminator can flow into the filtration chamber 12 through the downward flow port 113. By providing the anti-wave plates 132, waves in the oil-water separation chamber 13 are avoided, which affects the oil-water separation. On the outer wall of each anti-wave plate 132, several through holes 133 are provided, so that the liquid levels between the anti-wave plates 132 are at the same height. The anti-wave plates 132 and the overflow partition plate 142 are of the same height, and the height of the reflux slope 123 is higher than that of the anti-wave plates 132 and the overflow partition plate 142. The gas-liquid separation chamber 11 is located above the filtration chamber 12, and the filtration chamber 12 is located above the oil-water separation chamber 13, so that the overall floor area of the device is reduced. An anti-vortex device is provided in the drain port 131 to avoid vortex generation during drainage, which causes the oil and water to mix again.

[0032] For further elaboration on the above content: The mixed liquid is transported into the gas-liquid separation chamber 11 through the liquid inlet 111. The mixed liquid impacts on the inlet baffle 2 obliquely below the liquid inlet 111, and the liquid column of the mixed liquid is dispersed, thereby releasing the gas wrapped in the mixed liquid and buffering the mixed liquid at the same time to achieve gas-liquid separation. The separated gas is discharged through the exhaust port 112. The mixed liquid falls to the bottom of the gas-liquid separation chamber 11 and then flows into the filtration chamber 12 through the downward flow port 113. The mixed liquid is filtered by the provided filtration mechanism, and the filtered impurities are collected by the collection frame 4. The mixed liquid after filtration falls into the oil-water separation chamber 13, and the oil floats on the water surface to achieve oil-water separation. The oil overflows the overflow partition 142 and enters the oil collection chamber 14 to achieve oil-water separation. Through the provided prompting mechanism, the water level in the tank body 1 can be observed, the water is discharged through the drain port 131, and the oil is discharged through the oil drain port 141.

[0033] Specifically, the filtration mechanism includes an inlet baffle 2, a collection frame 4, and a holder 5. A first chute 122 and an installation groove 124 are formed on the inner wall of the filtration chamber 12. The first chute 122 is an inclined chute, and the inclination direction of the first chute 122 is opposite to the inclination direction of the reflux inclined surface 123. A second chute 125 is formed on the inner wall of the filtration chamber 12. The second chute 125 is parallel to the first chute 122, and the second chute 125 extends into the installation groove 124. The inlet baffle 2 is rotatably inserted on the inner wall of the gas-liquid separation chamber 11. The inlet baffle 2 is located obliquely below the liquid inlet 111. A driving wheel 21 is welded on the outer wall of one side of the inlet baffle 2. The driving wheel 21 is rotatably inserted on the outer wall of the tank body 1. A driven wheel 3 is rotatably inserted on the outer wall of the tank body 1. A transmission belt 32 is sleeved on the outer walls of the driven wheel 3 and the driving wheel 21. A transmission wheel 33 is welded on the outer wall of one side of the driven wheel 3 close to the filtration chamber 12. The transmission wheel 33 is rotatably inserted in the installation groove 124. A clamping groove 34 is formed on the outer wall of the transmission wheel 33 away from the driven wheel 3. A handle 31 is welded on the outer wall of the driven wheel 3 away from the filtration chamber 12. The handle 31 is parallel to the clamping groove 34. The collection frame 4 is slidably inserted in the filtration chamber 12. A sliding column 42 is welded on the outer wall of the end of the collection frame 4. The sliding column 42 is slidably inserted in the first chute 122. The bottom of the end of the collection frame 4 away from the sliding column 42 abuts against the reflux inclined surface 123. A water baffle 41 is welded on the bottom of the inner wall of the collection frame 4. A water filtering hole 43 is formed on the bottom of the inner wall of the collection frame 4. A holder 5 is rotatably inserted on the inner wall of one side of the collection frame 4 close to the sliding column 42. The holder 5 is located obliquely below the downward flow port 113. A corrugated filter screen 51 is adhered to the outer wall of the holder 5. A clamping block 52 is welded on the rotating shaft of the holder 5. The clamping block 52 is adapted to the clamping groove 34. The clamping block 52 is adapted to the second chute 125.

[0034] As Figure 8As shown, the inlet baffle 2 is located obliquely below the liquid inlet 111 and on the side away from the cage 5. The cage 5 is located obliquely below the downstream port 113 and on the side away from the inlet baffle 2. Under the driving action of the inlet baffle 2, the cage 5 rotates counterclockwise, preventing the filter screen 51 from being washed down into the oil-water separation chamber 13 by the mixed liquid when it rotates along the flow direction of the mixed liquid, that is, when it rotates clockwise. The second chute 125 extends to the outside of the tank body 1, enabling the clamping block 52 to slide out of the tank body 1 along the second chute 125. The end of the first chute 122 extends beyond the return slope 123 but does not exceed the outer wall of the tank body 1, ensuring that the sliding column 42 does not fall off when it slides to the end of the first chute 122. The handle 31 is parallel to the card slot 34, so that when the handle 31 is rotated to be parallel to the second chute 125, the card slot 34 can be flush with the second chute 125. The corrugated filter screen 51 can keep impurities staying in the corrugated gaps, making it difficult for the impurities to be washed down by the mixed liquid.

[0035] The above filtering mechanism is further elaborated as follows: The mixed liquid impacts on the inlet baffle 2 obliquely below the liquid inlet 111, which can buffer the mixed liquid. The mixed liquid falls to the bottom of the gas-liquid separation chamber 11 and then flows into the filtration chamber 12 through the downstream port 113. The inlet baffle 2 rotates under the action of the impact force of the mixed liquid, causing the inlet baffle 2 to drive the driving wheel 21 to rotate. Under the action of the transmission belt 32, the driven wheel 3 rotates, causing the driven wheel 3 to drive the transmission wheel 33 to rotate. Thus, the transmission wheel 33 drives the card slot 34 to rotate. Under the cooperative action of the card slot 34 and the clamping block 52, the clamping block 52 rotates with the card slot 34. Furthermore, the clamping block 52 drives the cage 5 to rotate, and the cage 5 drives the filter screen 51 to rotate, realizing the filtration of the mixed liquid flowing out from the downstream port 113. During the rotation of the filter screen 51, the impurities intercepted by the filter screen 51 are poured into the collection frame 4 and collected. The mixed liquid splashed in the collection frame 4 will fall onto the return slope 123 through the water filter holes 43 at the bottom of the collection frame 4 and finally flow into the oil-water separation chamber 13 along the return slope 123. When it is necessary to clean the filtering mechanism, open the sealing door 121, rotate the handle 31, and rotate the card slot 34 to a state flush with the second chute 125, enabling the clamping block 52 to slide into the second chute 125 from the card slot 34, and pulling the collection frame 4 out of the filtration chamber 12. When the sliding column 42 slides to the end of the first chute 122, the collection frame 4 loses the abutting effect of the return slope 123 and flips downward, thus pouring out the impurities in the collection frame 4. At the same time, the collection frame 4 can drive the cage 5 to slide out of the filtration chamber 12 together, facilitating the cleaning and maintenance of the filter screen 51 on the cage 5.

[0036] Specifically, the prompting mechanism includes a benchmark 6. The top inner wall of the oil-water separation chamber 13 is slidably inserted with the benchmark 6. The benchmark 6 is coaxially distributed with the drain port 131. The benchmark 6 extends to the outside of the tank body 1. A floating block 61 is bonded to the bottom end of the benchmark 6. The floating block 61 is adapted to the drain port 131. Scale lines 62 are printed on the outer wall of the top end of the benchmark 6. A connecting rod 7 is connected to the top end of the benchmark 6 through a rotating shaft. The end of the connecting rod 7 away from the benchmark 6 is rotatably connected to a sealing plate 8 through a rotating shaft. The sealing plate 8 is slidably inserted into the top inner wall of the gas-liquid separation chamber 11. The sealing plate 8 is adapted to the liquid inlet 111. The end of the filtering chamber 12 is rotatably connected to a sealing door 121 through a hinge. An oil drain hole 143 is opened at the bottom of the outer wall of the overflow partition plate 142. A sealing disk 9 is rotatably inserted into the overflow partition plate 142. A pair of symmetric docking holes 91 are opened on the outer wall of the sealing disk 9. Each docking hole 91 is adapted to the oil drain hole 143. An operating rod 92 is welded to the outer wall of the side of the sealing disk 9 away from the wave-proof plate 132. The operating rod 92 extends to the outside of the tank body 1. A cross handle 93 is welded to the end of the operating rod 92 away from the sealing disk 9.

[0037] The connection between the benchmark 6 and the tank body 1 is by a dynamic sealing method to ensure the airtightness of the whole device. The floating block 61 is a plastic floating object that can float on the water surface and sink under the oil. The buoyancy of the floating block 61 should be greater than the masses of the benchmark 6, the connecting rod 7 and the sealing plate 8 to ensure that the floating block 61 can float and drive the benchmark 6 to rise. The connection between the sealing plate 8 and the top inner wall of the gas-liquid separation chamber 11 is by a dynamic sealing connection to ensure the sealing of the whole device. A sealing ring is bonded to the outer wall of the sealing door 121 to improve the airtightness of the device. The connection between the sealing disk 9 and the overflow partition plate 142 is by a dynamic sealing connection. The cross handle 93 is composed of two handles, one short and one long, vertically welded. The axis of the short handle is parallel to the center line connection of the docking holes 91. When the short handle is rotated to the vertical state, the docking holes 91 are communicated with the oil drain hole 143, thus opening the oil drain hole 143. The floating block 61 is adapted to the drain port 131 to enable the closing of the drain port 131.

[0038] Further elaboration on the above prompt mechanism: When the mixed liquid enters the oil-water separation chamber 13, the water in the mixed liquid can drive the floating block 61 to float, enabling the floating block 61 to drive the lever 6 to rise. By observing the scale line 62 on the lever 6, the water level height in the oil-water separation chamber 13 can be known. At the same time, by observing the fluctuation frequency of the lever 6, the wave fluctuation situation of the liquid level in the tank body 1 can be known, thereby being able to prompt the staff to reduce the flow rate of the mixed liquid at the liquid inlet 111, and further being able to reduce the fluctuation of the liquid level in the tank body 1. When the water level height in the oil-water separation chamber 13 is too high, the lever 6 drives the connecting rod 7 to swing, causing the connecting rod 7 to drive the sealing plate 8 to slide towards the liquid inlet 111, so that the sealing plate 8 closes the liquid inlet 111, preventing the entry of the mixed liquid, and further preventing the water level height in the oil-water separation chamber 13 from rising further. When the mixed liquid is less, resulting in insufficient water level height and the oil overflowing the overflow partition 142, the drain port 131 is opened to drain the water, and the floating block 61 falls back into the drain port 131, thus closing the drain port 131. The cross handle 93 is rotated to open the oil drain hole 143, enabling the oil in the oil-water separation chamber 13 to enter the oil collection chamber 14 through the oil drain hole 143. At this time, opening the oil drain port 141 can drain all the oil.

[0039] The working principle and usage process of the present invention: Before the device works, the cross handle 93 is rotated to turn the long handle to the vertical state, so that the sealing disk 9 closes the oil drain hole 143. The mixed liquid is conveyed into the gas-liquid separation chamber 11 through the liquid inlet 111. The mixed liquid impacts on the inlet baffle 2 obliquely below the liquid inlet 111, causing the liquid column of the mixed liquid to be dispersed, thereby releasing the gas wrapped in the mixed liquid and buffering the mixed liquid at the same time, realizing gas-liquid separation. The separated gas is discharged through the exhaust port 112. The mixed liquid falls to the bottom of the gas-liquid separation chamber 11 and then flows into the filtration chamber 12 through the downstream port 113. The mixed liquid is filtered through the provided filtration mechanism, and the filtered impurities are collected by the collection frame 4. The filtered mixed liquid falls into the oil-water separation chamber 13, and the oil floats on the water surface to achieve oil-liquid separation. The oil overflows the overflow partition 142 and enters the oil collection chamber 14 to achieve oil-water separation. Through the provided prompt mechanism, the water level height in the tank body 1 can be observed. After standing and separating for a period of time, the water is discharged through the drain port 131, and the oil is discharged through the oil drain port 141.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
