Description

Technical Field

[0001] The invention belongs to the technical field of oil, gas and water separation, and in particular relates to an industrial three-phase separator capable of filtering oil, gas and water. Background Art

[0002] The oil, gas and water three-phase separator is one of the most commonly used equipment in the oil field development and production process. Its working principle is to use the gravity sedimentation effect to discharge the gas in the oil, gas and water mixture from the exhaust port on the top of the three-phase separator, while the oil floats on the water surface and overflows through the overflow baffle. However, in the process of oil extraction, the oil, gas and 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 can easily cause blockage in the drain pipe.

[0003] However, the existing three-phase separator does not have a filtering function, and a filtering device needs to be added at the liquid inlet. Cleaning and maintenance of the filtering device will increase production costs. In addition, the existing three-phase separator cannot observe the liquid level inside the tank from the outside. When the water content in the mixed liquid is large, it is easy to cause the water in the tank to overflow the baffle, thereby causing the separated oil to mix with the water again.

A driving wheel is welded on the outer wall of one side of the inlet baffle, and the driving wheel is rotatably inserted on the outer wall of the tank body. A driven wheel is rotatably inserted on the outer wall of the tank body, and a transmission belt is mounted on the outer wall of the driven wheel and the outer wall of the driving wheel.

[0008] In the above-mentioned industrial three-phase separator that can filter oil, gas and water, a transmission wheel is welded on the outer wall of the driven wheel close to the filter chamber, and the transmission wheel is rotatably inserted in the installation groove. A clamping groove is opened on the outer wall of the transmission wheel away from the driven wheel, and a handle is welded on the outer wall of the driven wheel away from the filter chamber, and the handle is parallel to the clamping groove.

[0009] In the above-mentioned industrial three-phase separator that can filter oil, gas and water, the collecting frame is slidably inserted in the filter chamber, a sliding column is welded on the outer wall of the end of the collecting frame, the sliding column is slidably inserted in a slide groove, the bottom of the outer wall of one end of the collecting frame away from the sliding column abuts against the reflux slope, a water baffle is welded on the bottom of the inner wall of the collecting frame, and a water filter hole is opened at the bottom of the inner wall of the collecting frame.

[0010] In the above-mentioned industrial three-phase separator that can filter oil, gas and water, a retaining frame is rotatably inserted on the inner wall of one side of the collecting frame close to the sliding column, and the retaining frame is located obliquely below the downstream outlet.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the provided filtering mechanism, when the mixed liquid enters the gas-liquid separation chamber through the liquid inlet, the mixed liquid hits the inlet baffle plate obliquely below the liquid inlet, and the liquid column of the mixed liquid is dispersed, so that the gas contained in the mixed liquid is released and the mixed liquid is buffered at the same time. The mixed liquid falls to the bottom of the gas-liquid separation chamber, and then flows into the filter chamber through the downstream port. The inlet baffle plate rotates under the impact force of the mixed liquid, so that the inlet baffle plate drives the driving wheel to rotate, and under the action of the transmission belt, the driven wheel rotates, so that the driven wheel drives the transmission wheel to rotate, so that the transmission wheel drives the card slot to rotate, and under the cooperation of the card slot and the card block, the card block rotates with the card slot, and then the card block drives the retaining frame to rotate, and the retaining frame drives the filter screen to rotate, so as to achieve the effect of the gas-liquid separation chamber from the downstream port. The mixed liquid flowing out of the filter outlet is filtered. During the rotation of the filter screen, the impurities intercepted by the filter screen are dumped into the collection frame and collected. The mixed liquid splashed in the collection frame will fall onto the reflux slope through the water filter hole at the bottom of the collection frame, and finally flow into the oil-water stratification chamber along the reflux slope. When it is necessary to clean and maintain the filter mechanism, the sealing door is opened, the handle is rotated, and the card slot is rotated to a state flush with the second slide slot, so that the card block can slide from the card slot into the second slide slot, and the collection frame is pulled out of the filter chamber. When the slide column slides to the end of the slide slot, the collection frame loses the abutment effect of the reflux slope and flips downward, thereby pouring out the impurities in the collection frame, and the collection frame drives the retaining frame to slide out of the filter chamber together, which is convenient for cleaning and maintenance of the filter screen on the retaining frame. 2. By setting a prompt mechanism, when the mixed liquid enters the oil-water stratification chamber, the water in the mixed liquid can drive the floating block to float up, so that the floating block can drive the benchmark to rise. By observing the scale line on the benchmark, the water level in the oil-water stratification chamber can be known. When the water level in the oil-water stratification chamber is too high, the benchmark drives the connecting rod to swing, so that the connecting rod drives the sealing plate to slide toward the liquid inlet, so that the sealing plate closes the liquid inlet, preventing the mixed liquid from entering, and further preventing the water level in the oil-water stratification chamber from rising; To summarize, through the setting of the filtering mechanism, the impurities in the mixed liquid can be filtered, and the filtered impurities are collected by the collecting frame to prevent the impurities from being deposited at the bottom of the tank of the three-phase separator. The collecting frame can drive the retaining frame to slide out of the filter chamber, which is convenient for cleaning and maintenance of the collection frame and the filter screen on the retaining frame. By setting the prompt mechanism, the outside world can know the water level in the oil-water stratification chamber by observing the scale line on the benchmark, thereby prompting the outside world to take corresponding measures in time to prevent the water in the tank from overflowing the partition.

A filtering mechanism is arranged in the filter chamber 12, and a prompt mechanism is arranged in the oil-water stratification chamber 13.

[0027] A mist collector is installed at the bottom end of the exhaust port 112 to collect the oil-water mixture carried in the gas. A downflow pipe is installed at the bottom of the mist collector, and the downflow pipe extends to above the downflow port 113. The oil-water mixture recovered by the mist collector can flow into the filter chamber 12 through the downflow port 113. The wave-breaking plate 132 is set to prevent waves from being generated in the oil-water stratification chamber 13 to affect the oil-water stratification. A plurality of through holes 133 are opened on the outer wall of each wave-breaking plate 132, so that the liquid levels between the wave-breaking plates 132 are at the same height, the wave-breaking plates 132 and the overflow baffles 142 are at the same height, and the height of the reflux slope 123 is higher than that of the wave-breaking plates 132 and the overflow baffles 142. The gas-liquid separation chamber 11 is located above the filter chamber 12, and the filter chamber 12 is located above the oil-water stratification chamber 13, so that the overall footprint of the device is reduced. A vortex preventer is set in the drain port 131 to prevent vortices from being generated during drainage and causing oil and water to mix again.

[0028] The above content is further elaborated: the mixed liquid is transported into the gas-liquid separation chamber 11 through the liquid inlet 111, and the mixed liquid hits the inlet baffle 2 obliquely below the liquid inlet 111, and the liquid column of the mixed liquid is dispersed, thereby releasing the gas contained in the mixed liquid and buffering the mixed liquid at the same time, realizing gas-liquid separation, and the separated gas is discharged through the exhaust port 112, and the mixed liquid falls to the bottom of the gas-liquid separation chamber 11, and then flows into the filter chamber 12 through the downstream port 113, and the mixed liquid is filtered by the provided filtering mechanism, and the filtered impurities are collected by the collecting frame 4, and the filtered mixed liquid falls into the oil-water stratification chamber 13, and the oil floats on the water surface to realize oil stratification, and the oil overflows the overflow partition 142 and enters the oil collecting chamber 14 to realize oil-water separation, and the water level in the tank body 1 can be observed through the provided prompt mechanism, and the water is discharged through the drain port 131, and the oil is discharged through the oil discharge port 141.

[0029] Specifically, the filtering mechanism includes an inlet baffle 2, a collecting frame 4 and a retaining frame 5. A chute 122 and a mounting groove 124 are provided on the inner wall of the filter chamber 12. The chute 122 is an inclined groove. The inclination direction of the chute 122 is opposite to the inclination direction of the reflux inclined surface 123. A chute 2 125 is provided on the inner wall of the filter chamber 12. The chute 2 125 is parallel to the chute 122. The chute 2 125 extends into the mounting groove 124. The gas-liquid separation chamber 1 An inlet baffle 2 is rotatably plugged on the inner wall of the tank body 1, and 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, and the driving wheel 21 is rotatably plugged on the outer wall of the tank body 1. A driven wheel 3 is rotatably plugged on the outer wall of the tank body 1, and a transmission belt 32 is sleeved on the outer wall of the driven wheel 3 and the outer wall of the driving wheel 21. A transmission wheel 33 is welded on the outer wall of the driven wheel 3 close to the filter chamber 12, and the transmission wheel 33 rotates. The driven wheel 33 is movably inserted in the installation groove 124, and a slot 34 is provided on the outer wall of the side of the driving wheel 33 away from the driven wheel 3. A handle 31 is welded on the outer wall of the side of the driven wheel 3 away from the filter chamber 12. The handle 31 is parallel to the slot 34. The collection frame 4 is slidably inserted in the filter 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 slide groove 122. The bottom of the outer wall of the end of the collection frame 4 away from the sliding column 42 is connected to the reflux slope. 123 is abutted, a water baffle 41 is welded to the bottom of the inner wall of the collecting frame 4, a water filtering hole 43 is opened at the bottom of the inner wall of the collecting frame 4, a retaining frame 5 is rotatably inserted on the inner wall of the collecting frame 4 on one side close to the sliding column 42, the retaining frame 5 is located obliquely below the downstream outlet 113, a corrugated filter screen 51 is bonded to the outer wall of the retaining frame 5, a clamping block 52 is welded on the rotating shaft of the retaining frame 5, the clamping block 52 is adapted to the clamping slot 34, and the clamping block 52 is adapted to the slide slot 125.

[0030] like Figure 8As shown, the inlet baffle 2 is located obliquely below the liquid inlet 111 and on the side away from the retainer 5, and the retainer 5 is located obliquely below the downstream port 113 and on the side away from the inlet baffle 2, so that under the driving action of the inlet baffle 2, the retainer 5 rotates counterclockwise to prevent the filter screen 51 from rotating along the flow direction of the mixed liquid, that is, when rotating clockwise, causing the filtered impurities to be washed into the oil-water stratification chamber 13 by the mixed liquid, and the second chute 125 extends to the outside of the tank body 1, so that The block 52 can slide out of the tank body 1 along the second slide groove 125. The end of the first slide groove 122 exceeds the reflux slope 123, but does not exceed the outer wall of the tank body 1, so that the slide column 42 will not fall off when it slides to the end of the first slide groove 122. The handle 31 is parallel to the slot 34, so that when the handle 31 is rotated to be parallel to the second slide groove 125, the slot 34 can be flush with the second slide groove 125. The corrugated filter 51 can make impurities stay in the corrugated gap, so that the impurities are not easily washed away by the mixed liquid.

[0031] The above-mentioned filtering mechanism is further explained: the mixed liquid hits 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 filter chamber 12 through the downstream port 113. The inlet baffle 2 rotates under the impact force of the mixed liquid, so that the inlet baffle 2 drives the driving wheel 21 to rotate. Under the action of the transmission belt 32, the driven wheel 3 rotates, so that the driven wheel 3 drives the transmission wheel 33 to rotate, so that the transmission wheel 33 drives the slot 34 to rotate. Under the cooperation of the slot 34 and the block 52, the block 52 rotates with the slot 34, so that the block 52 drives the retaining frame 5 to rotate, and the retaining frame 5 drives the filter screen 51 to rotate, so as to filter the mixed liquid flowing out of the downstream port 113. During the rotation of the filter screen 51, the filter screen 5 The impurities intercepted by 1 are dumped into the collecting frame 4 and collected. The mixed liquid splashed in the collecting frame 4 will fall onto the reflux slope 123 through the water filtering hole 43 at the bottom of the collecting frame 4, and finally flow into the oil-water stratification chamber 13 along the reflux slope 123. When it is necessary to clean the filtering mechanism, the sealing door 121 is opened, the handle 31 is rotated, and the card slot 34 is rotated to be flush with the second slide slot 125, so that the card block 52 can slide from the card slot 34 into the second slide slot 125, and the collecting frame 4 is pulled out of the filter chamber 12. When the slide column 42 slides to the end of the slide slot 122, the collecting frame 4 loses the abutment effect of the reflux slope 123 and flips downward, thereby pouring out the impurities in the collecting frame 4. At the same time, the collecting frame 4 can drive the retaining frame 5 to slide out of the filter chamber 12 together, so as to facilitate the cleaning and maintenance of the filter screen 51 on the retaining frame 5.

[0032] Specifically, the prompt mechanism includes a benchmark rod 6, the top of the inner wall of the oil-water stratification chamber 13 is slidably plugged with the benchmark rod 6, the benchmark rod 6 and the drain port 131 are coaxially distributed, the benchmark rod 6 extends to the outside of the tank body 1, the bottom of the benchmark rod 6 is bonded with a floating block 61, the floating block 61 is adapted to the drain port 131, and a scale line 62 is printed on the top outer wall of the benchmark rod 6. The top of the benchmark rod 6 is connected to a connecting rod 7 through a rotating shaft, and the end of the connecting rod 7 away from the benchmark rod 6 is rotatably connected to a sealing plate 8 through a rotating shaft. The sealing plate 8 is slidably plugged on the top inner wall of the gas-liquid separation chamber 11, and the sealing plate 8 is The liquid inlet 111 is adapted, and the end of the filter chamber 12 is rotatably connected to the sealing door 121 through a hinge. An oil drain hole 143 is provided at the bottom of the outer wall of the overflow baffle 142. A sealing disk 9 is rotatably inserted in the overflow baffle 142. A pair of symmetrical docking holes 91 are provided on the outer wall of the sealing disk 9, and each docking hole 91 is adapted to the oil drain hole 143. An operating rod 92 is welded on the outer wall of the sealing disk 9 away from the wave-breaking plate 132. The operating rod 92 extends to the outside of the tank body 1, and a cross handle 93 is welded on the end of the operating rod 92 away from the sealing disk 9.

[0033] The benchmark 6 and the tank body 1 are connected by a dynamic seal to ensure the overall airtightness of the device. The float 61 is a plastic floating object that can float on the water surface and sink under the oil. The buoyancy of the float 61 should be greater than the mass of the benchmark 6, the connecting rod 7 and the sealing plate 8 to ensure that the float 61 can float and drive the benchmark 6 to rise. The sealing plate 8 and the top inner wall of the gas-liquid separation chamber 11 are connected by a dynamic seal to ensure the overall airtightness of the device. A sealing ring is bonded to the outer wall of the sealing door 121 to improve the airtightness of the device. The sealing disk 9 and the overflow partition 142 are connected by a dynamic seal. The cross handle 93 is a short and a long handle vertically welded, wherein the axis of the short handle is parallel to the center line of the docking hole 91, so that when the short handle is rotated to a vertical state, the docking hole 91 is connected to the oil drain hole 143, thereby opening the oil drain hole 143, and the float 61 is adapted to the drain port 131 so that the drain port 131 can be closed.

[0034] The above-mentioned prompt mechanism is further elaborated: when the mixed liquid enters the oil-water stratification chamber 13, the water in the mixed liquid can drive the float 61 to float, so that the float 61 can drive the benchmark 6 to rise. By observing the scale line 62 on the benchmark 6, the water level in the oil-water stratification chamber 13 can be known. At the same time, by observing the fluctuation frequency of the benchmark 6, the fluctuation of the liquid level in the tank body 1 can be known, so that the staff can be prompted to reduce the flow rate of the mixed liquid at the liquid inlet 111, thereby reducing the fluctuation of the liquid level in the tank body 1. When the water level in the oil-water stratification chamber 13 is too high, the benchmark 6 drives the connecting rod 7 to swing, so that the connecting rod 7 The rod 7 drives the sealing plate 8 to slide toward the liquid inlet 111, so that the sealing plate 8 closes the liquid inlet 111, preventing the mixed liquid from entering, and further preventing the water level in the oil-water stratification chamber 13 from rising further. When the mixed liquid is less, resulting in insufficient water level so that the oil overflows the overflow baffle 142, the drain port 131 is opened to drain the water, and the floating block 61 falls back into the drain port 131, thereby closing the drain port 131, and turning the cross handle 93 to open the oil drain hole 143, so that the oil in the oil-water stratification chamber 13 enters the oil collecting chamber 14 through the oil drain hole 143. At this time, opening the oil drain port 141 can discharge all the oil.

[0035] The working principle and use process of the present invention are as follows: before the device is operated, the cross handle 93 is rotated, and the long handle is rotated to a vertical state, so that the sealing disk 9 closes the oil drain hole 143, and the mixed liquid is transported into the gas-liquid separation chamber 11 through the liquid inlet 111. The mixed liquid hits the inlet baffle 2 obliquely below the liquid inlet 111, so that the liquid column of the mixed liquid is dispersed, thereby releasing the gas contained in the mixed liquid and buffering the mixed liquid at the same time, realizing gas-liquid separation, and the separated gas is discharged through the exhaust port 112, and the mixed liquid falls to the gas-liquid separation chamber 11. The bottom of the tank 1 is filtered, and then flows into the filter chamber 12 through the downstream port 113. The mixed liquid is filtered by the provided filtering mechanism, and the filtered impurities are collected by the collecting frame 4. The filtered mixed liquid falls into the oil-water stratification chamber 13, and the oil floats on the water surface to achieve oil stratification. The oil flows over the overflow partition 142 and enters the oil collecting chamber 14 to achieve oil-water separation. The water level in the tank body 1 can be observed through the provided prompt mechanism. After a period of static stratification, the water is discharged through the drain port 131, and the oil is discharged through the oil discharge port 141.
