Description

Technical Field

[0001] This utility model relates to the field of petroleum processing equipment technology, and in particular to a high-efficiency temperature-controllable oil-gas-water three-phase separator. Background Technology

[0002] During the oil production process, oil and formation water are produced simultaneously, so it is necessary to separate the oil and water. The wastewater after separation still contains oil and a small amount of hydrocarbon gas. If the wastewater containing oil and gas is discharged directly without treatment, it will cause pollution and harm to the environment. Therefore, a three-phase separator is needed to treat the above wastewater and achieve the separation of oil, gas and water. Because the wastewater contains impurities, the impurities are prone to clogging when the separator is separating the wastewater.

[0003] For example, in the prior art, the patent with authorization announcement number CN221141367U discloses a high-efficiency temperature-controllable oil-gas-water three-phase separator. This device, by setting a filter component, can perform preliminary sedimentation on the oil-liquid mixture delivered to the filter box by the inlet pipe. When the oil-liquid mixture fills the filter box, the oil floats up and comes into contact with the filter screen plate. The filter screen plate filters the oil, so that no impurities will precipitate after the oil enters the separation tank, effectively preventing impurities from clogging the drain pipe and improving the oil separation efficiency.

[0004] However, the drain pipe of this device runs directly through the side of the filter box. When there are too many impurities such as sand in the filter box, they cannot be discharged directly from the drain pipe, which can easily lead to blockage of the drain pipe. In addition, the device drives the fan blade to rotate through the flow of water mixed with oil and water, which in turn drives the rotating rod and the cleaning brush plate to rotate. Since the cleaning brush plate is located inside the filter box, which is filled with oil and water mixture, the resistance during rotation is large. The water flow impact makes it difficult to make the rotating rod and the cleaning brush plate rotate, which makes it difficult to achieve the cleaning effect of the filter screen plate. The filter screen plate is easily blocked, affecting normal filtration. Therefore, a high-efficiency temperature-controllable oil-gas-water three-phase separator is designed to solve the above problems. Utility Model Content

[0008] A through-pipe is installed through the top of the filter box, and the top of the through-pipe is installed through the center of the bottom of the separation box. A filter screen is fixedly installed on the bottom inner side of the through-pipe. A drain valve is installed through the right side of the separation box. The liquid inlet pipe passes through and extends into the bottom of the filter screen. A drain assembly is installed on the filter box to facilitate the discharge of impurities. A cleaning assembly for cleaning the filter screen is installed inside the liquid inlet pipe. A linkage assembly is installed on the exhaust fan to drive the cleaning assembly to clean the filter screen.

[0009] Preferably, an electric heating plate is fixedly installed on the left side inside the filter box, a temperature sensor is installed on the left side of the electric heating plate, and a controller is also installed on the filter box.

[0017] 1. This utility model incorporates a filter box. When separating an oil-water mixture, the mixture enters the filter box, where impurities are filtered out by the filter screen. The mixture then overflows into the separation box through a through-pipe. A partition separates the oil-water mixture on the left side of the separation box. Due to the density difference between oil and water, the oil floats on the water. When the oil level is level with the upper surface of the partition, the oil overflows through the partition and flows to the right side, achieving oil-water separation. Simultaneously, an exhaust fan is activated, which extracts and collects the vapors in the oil and water through the exhaust pipe, achieving oil-gas separation. The drain valve is opened, and the oil is discharged and collected. When water is discharged from the drain valve, it indicates that the water level inside the separation box is higher than the upper surface of the partition. The drain valve is then opened to drain the water from the separation box.

The rotating wheel drives the auger to rotate, and the auger drives the filtered sand and other impurities out of the sewage discharge valve, preventing the sand and other impurities from clogging the sewage discharge valve and ensuring normal sewage discharge.

[0020] 4. This utility model is equipped with a cleaning component and a linkage component. When the exhaust fan is blowing air, the exhaust fan rotates, which drives the connecting rod and the second bevel gear to rotate. The second bevel gear drives the first bevel gear and the rotating shaft to rotate, so that the brush on the horizontal plate cleans the filter screen, ensuring the cleanliness of the filter screen, preventing the filter screen from clogging, and ensuring the filtration effect of the filter screen.

[0029] Example: Figures 1-5 As shown, an embodiment of this utility model provides a high-efficiency temperature-controllable oil-gas-water three-phase separator, including a separation box 1. Support legs 2 are fixedly installed on both the left and right sides of the bottom surface of the separation box 1. An inlet pipe 3 is installed through the center of the upper surface of the separation box 1. An exhaust pipe 4 is installed through the right side of the upper surface of the separation box 1. An exhaust fan 5 is fixedly installed inside the exhaust pipe 4. A partition 6 is fixedly installed on the right side of the bottom of the separation box 1. A drain valve 7 is installed through the bottom left side of the separation box 1. An oil drain valve 8 is installed through the bottom right side of the separation box 1. A filter box 9 is installed through the center of the bottom of the separation box 1.

[0030] A through pipe 901 is installed through the top of the filter box 9. The top of the through pipe 901 is installed through the center of the bottom of the separation box 1. A filter screen 902 is fixedly installed inside the bottom of the through pipe 901. A drain valve 903 is installed through the right side of the separation box 1. An inlet pipe 3 passes through and extends into the bottom of the filter screen 902. A drain assembly is installed on the filter box 9 to facilitate the discharge of impurities. A cleaning assembly for cleaning the filter screen 902 is installed inside the inlet pipe 3. A linkage assembly for driving the cleaning assembly to clean the filter screen 902 is installed on the exhaust fan 5.

[0031] With the filter box 9 installed, when separating the oil-water mixture, the oil-water mixture enters the filter box 9, and after the impurities in the oil-water mixture are filtered by the filter screen 902, it overflows into the separation box 1 through the through pipe 901. The baffle 6 can block the oil-water mixture on the left side of the separation box 1. Due to the density difference between oil and water, the oil will float on the water. When the oil level is level with the upper surface of the baffle 6, the oil will overflow the baffle 6 and flow into the right side of the baffle, thus achieving oil-water separation. At the same time, the exhaust fan 5 is turned on, and the exhaust fan 5 will draw out the vapors in the oil and water through the exhaust pipe for collection, thus achieving the effect of oil-gas separation. The oil drain valve 8 is opened, and the oil is discharged from the oil drain valve 8 for collection. When the oil drain valve 8 discharges water, it means that the water level in the separation box 1 is higher than the water level of the upper surface of the baffle 6. The drain valve 7 is then opened to drain the water from the separation box 1.

[0032] In this embodiment, an electric heating plate 10 is fixedly installed on the left side inside the filter box 9, and a temperature sensor 11 is installed on the left side of the electric heating plate 10. A controller is also installed on the filter box 9, and the electric heating plate 10 and the temperature sensor 11 are both electrically connected to the controller.

[0033] By providing an electric heating plate 10 and a temperature sensor 11, the electric heating plate 10 can heat the oil-water mixture in the separation chamber 1 to increase the separation effect. The temperature sensor 11 senses the temperature of the oil-water compound, and the controller sets the temperature required for separation. The controller controls the temperature of the oil-water mixture by opening and closing the electric heating plate 10, thus ensuring separation efficiency.

[0034] In this embodiment, the bottom of the filter box 9 is in the shape of a semi-circular arc that matches the drain valve 903, and the drain valve 903 passes through the semi-circular end of the bottom of the filter box 9.

[0035] In this embodiment, the sewage discharge assembly includes an auger 904 and a rotor 905. The auger 904 is rotatably mounted below the left side surface of the filter box 9 via a waterproof bearing, and the rotor 905 is fixedly mounted on the left end of the auger 904.

[0036] In this embodiment, the auger 904 is embedded in the semi-circular arc at the bottom of the filter box 9, and the right end of the auger 904 extends into the drain valve 903, so that the auger 904 can discharge the filtered impurities.

[0037] By installing a sewage discharge component, when it is necessary to discharge sand particles and other impurities filtered out by the filter box 9, the sewage discharge valve 903 is opened, the rotating wheel 905 is rotated, the rotating wheel 905 drives the auger to rotate, and the auger 904 drives the filtered sand particles and other impurities to be discharged from the sewage discharge valve 903, preventing sand particles and other impurities from clogging the sewage discharge valve and ensuring normal sewage discharge.

[0038] In this embodiment, the cleaning component includes a rotating shaft 12, a horizontal plate 1201, a brush 1202, and a first bevel gear 1203. The rotating shaft 12 is installed in the liquid inlet pipe 3 via a mounting crossbar, and the rotating shaft 12 is rotatably mounted on the mounting crossbar. The bottom of the rotating shaft 12 is fixedly provided with the horizontal plate 1201, the upper surface of the horizontal plate 1201 is fixedly provided with the brush 1202, and the top of the rotating shaft 12 is fixedly provided with the first bevel gear 1203. The linkage component can drive the rotating shaft 12 to rotate by rotating the exhaust fan.

[0039] In this embodiment, the upper surface of the brush 1202 is attached to the bottom surface of the filter screen 902, which facilitates the brush 1202 to clean the bottom surface of the filter screen 902 and ensures the cleanliness of the filter screen 902.

[0040] In this embodiment, the linkage component includes a connecting rod 501, which is fixedly mounted on the output shaft of the exhaust fan 5. The connecting rod 501 rotates through a waterproof bearing and passes through the side of the exhaust pipe 4 and the liquid inlet pipe 3. A second bevel gear 502 is fixedly mounted at the end of the connecting rod 501.

[0041] In this embodiment, the second bevel gear 502 meshes with the first bevel gear 1203, which facilitates the second bevel gear 502 driving the first bevel gear 1203 to rotate.

[0042] By incorporating cleaning and linkage components, when the exhaust fan 5 is drawing air, the exhaust fan 5 rotates, causing the connecting rod 501 and the second bevel gear 502 to rotate. The second bevel gear 502 then drives the first bevel gear 1203 and the rotating shaft 12 to rotate, causing the brush 1202 on the horizontal plate 1201 to clean the filter screen 902, ensuring the cleanliness of the filter screen 902, preventing clogging, and ensuring the filtration effect of the filter screen 902.

[0043] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
