Description

Technical Field

[0001] This utility model relates to the field of marine oil engineering, and in particular to a coalescing oil-water separator for offshore platforms. Background Technology

[0002] The coalescing oil-water separator for offshore platforms is a specialized device applied to offshore oil platforms. It utilizes the coalescing principle (using specific materials and structures to cause tiny oil droplets to collide and aggregate into larger droplets) to treat oily wastewater generated during oil extraction and production, achieving efficient separation of oil and water. This ensures the recovery and reuse of crude oil to improve production efficiency, while also ensuring that the treated wastewater meets environmental discharge standards, reducing pollution to the marine environment. It is a key device in offshore oil and gas production that combines production assurance and environmental protection functions.

[0003] Offshore platform coalescing oil-water separators typically consist of a pretreatment unit, a coalescing separation unit (including a coalescing filter element to promote the aggregation of tiny oil droplets), a sedimentation separation unit, and a purified water output unit. Their working principle involves pretreatment to remove large particulate impurities from oily wastewater before it enters the coalescing separation unit. Through the adsorption and collision of the coalescing material, tiny oil droplets aggregate into larger droplets. Subsequently, in the sedimentation separation unit, the difference in gravity helps to separate the oil and water, ultimately resulting in purified water being discharged in compliance with standards, while the oil is recovered and further processed.

[0004] In existing technologies, the coalescing oil-water separators used on offshore platforms cannot clean their internal filters, leading to the gradual adhesion of impurities and sludge from oily wastewater to the filters. This clogs the filter pores, increases the resistance to wastewater flow, and slows down the filtration speed, failing to meet the platform's normal wastewater treatment capacity requirements and thus affecting the continuity of the entire oil and gas production process. The new design utilizes cleaning brushes inside the coalescing oil-water separator for offshore platforms to clean the filters. These brushes promptly remove impurities and sludge adhering to the filters, preventing clogging and ensuring smooth wastewater flow. This ensures the device maintains its designed treatment capacity, sustains the continuity of the entire wastewater treatment process, and guarantees the stable operation of oil and gas production on the offshore platform. Therefore, a coalescing oil-water separator for offshore platforms is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a motor a drives a drive column to rotate a rotating plate outside the drive column. A fixed button a is located between the rotating plate and a fixed button a, allowing an extension plate to rotate outside the fixed button a, forming a reciprocating motion. A sliding groove is fixed outside the fixed plate, and a sliding column slides back and forth inside the sliding groove, driving a cleaning brush.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a coalescing oil-water separator for offshore platforms, comprising a motor a1, which serves as the power source for a cleaning drive system. The core function of motor a1 is to convert electrical energy into mechanical energy. Two drive columns 3 are fixedly connected to the drive end. The drive columns 3 efficiently transmit power from the motor to the actuators. Due to the rigid connection, a fixed plate 2 is externally fixedly connected. A rotating plate 4 is externally rotatably connected to the drive columns 3, and a fixed knob a5 is internally fixedly connected. The fixed knob a5 has a cylindrical and pin-shaped structure, fixed inside the rotating plate 4 and rotatably connected to the extension plate 6. The extension plate 6 does not deform under stress. A rotating knob a7 is internally rotatably connected to the sliding column 8, which is fixed to the outside of the sliding column 8 and rotatably connected to the end of the extension plate 6. The sliding column 8 can evenly clean the target surface, avoiding cleaning dead corners. Due to the high precision of the sliding fit, the movement is smooth and without jumping. A sliding groove 9 is externally rotatably connected to the sliding column 8. The cleaning brush 36 and the fixed plate 2 are externally fixedly connected to an oil-water separator 16. The oil-water separator 16 reduces vibration transmission during motor b14 operation, ensures stable rotation of the spiral blades 12, and reduces mechanical noise and wear caused by eccentricity. An oil drain tank 10 is internally fixedly connected to the oil drain tank 10, ensuring that the oil-water separation process is not affected by impurity accumulation and improving the continuous operation capability of the device. A filter screen 11 is internally fixedly connected to the filter screen 11, purifying the oil and improving the purity of the oil in subsequent processing and recovery. A spiral blade 12 is rotatably connected to the inner wall of the filter screen 11. The spiral blade 12 achieves centralized storage of oil through its internal cavity design, preventing the oil from mixing with unseparated wastewater again. The external casing is fitted with a connecting conveying pipe 13. The oil-water separation tank 16 achieves centralized storage of oil through its internal cavity design, preventing the oil from mixing with unseparated wastewater again. The top is fixedly connected to a support plate 15, which prevents the oil from leaking or mixing with other media during the conveying process, ensuring the sealing and directionality of the oil conveying. The top is fixedly connected to a motor b14, and the drive end of the motor b14 is fixedly connected to the spiral blade 12.

[0033] Reference Figures 2 to 4The oil-water separator 16 has a sewage pipe 17 fixedly connected internally. The sewage pipe 17 prevents water flow from disrupting the flow field inside the separator and affecting the separation effect. An externally detachable support column 18 is connected, facilitating future maintenance and replacement. A support column 19 is fixedly connected to the bottom of the external structure, and multiple contraction columns 20 are fixedly connected internally to the support column 19. The contraction columns 20 form a stable support system. A pressing spring 22 is fitted externally to ensure that the contraction function of the contraction columns 20 is within a safe range, preventing structural failure. The multiple contraction columns 20... All external fixed connections of the support column 19 have limit balls 21. The external detachable connection of the support column 19 is a fixed column a23, which maintains stable support for the load-bearing column 18. Multiple hollow blocks 24 are provided in the external fixed connection to ensure the stability of the sewage pipe 17 installation. The internal fixed connection is a fixing button b25, which enhances the load-bearing capacity of the connection structure and prevents the fixing button b25 from breaking due to stress concentration. The external fixed connection is a stabilizing plate 26, which adapts to different installation angles and improves the fixing effect of the fixed column a23 in complex environments. The bottom is fixedly connected to a rotating knob b27, which prevents it from sinking into the mounting surface and improves the overall support's anti-overturning capability. Both external fixed connections on the sides have limit plates 28, with fixing posts b29 fixedly connected inside the limit plates 28. The fixing posts b29 further enhance the fixing strength of the stabilizing plate 26, preventing it from slipping under vibration. External fixed connections include a connecting plate 30. The oil-water separator 16 is externally fixedly connected to two oil drain pipes 31, which enhance the overall stability of the support structure. The bottom rotating connection has two drain pipes... Oil drum 32, two oil discharge drums 32 realize the directional discharge of oil. The pipe diameter is designed to match the oil flow rate to ensure smooth discharge. The bottom drive end is fixedly connected to the motor c35. The oil-water separator 16 is fixedly connected to the outside of the impurity discharge pipe 33. The impurity discharge pipe 33 realizes the batch collection and discharge of oil. The rotating design makes it easy to transfer oil to external storage equipment. The bottom of the easy-to-operate impurity discharge drum 34 is fixedly connected. The bottom of the motor c35 is fixedly connected to the bottom of the oil-water separator 16. The outside of the connecting plate 30 is fixedly connected to the outside of the fixed column a23.

[0034] Working principle: The motor a1 drives the drive column 3 to rotate inside the fixed plate 2. During the rotation, the drive column 3 drives the rotating plate 4 outside the drive plate 3 to rotate. The other end of the rotating plate 4 has a fixed knob a5, and an extension plate 6 rotates outside the fixed knob a5. One end of the extension plate 6 has a rotating knob a7 rotating inside the extension plate 6. The sliding column 8 is fixed together with the rotating knob a7, and the sliding groove 9 is fixed outside the fixed plate 2. The sliding column 8 slides inside the sliding groove 9, forming a reciprocating motion that pushes the cleaning brush 36 fixed outside the sliding column 8 to clean the outside of the filter screen 11, thus cleaning the cleaning brush. 36 slides inside the drain box 10. Because the internal slot near the top of the drain box 10 facilitates cleaning of the brush, 36 slides inside the drain box 10. Large impurities are then driven by the motor b14 to rotate the spiral blade 12, which transports the large impurities inside the filter screen 11 through the impurity discharge pipe 33 to the impurity discharge bucket 34. The support plate 15 supports the motor b14. The conveying pipe 13 wraps the internal dirt and uses the spiral blade 12 to transport it. The oil stains filtered out inside the filter screen 11 are then discharged into the impurity discharge bucket 34 through the impurity discharge pipe 33.

[0035] Because the sewage pipe 17 is used to discharge sewage, the pipe becomes very heavy, which can lead to breakage in severe cases. A support column 18 at the bottom of the sewage pipe 17 provides support, and a fixed support column 19 at the bottom of the support column 18 is used. When the sewage pipe 17 is at different heights, the support column 19 can be pressed downwards. The sewage pipe 17 penetrates the inside of the oil-water separator 16. An oil drain pipe 31 is fixedly connected to the outside of the oil-water separator 16, and an oil drain tank 32 is connected to the bottom of the oil drain tank. When the motor c35 rotates, it drives the oil drain tank 32 to rotate. During the pressing process, the contraction column 20 and the pressing spring 22 inside the support column 19 contract towards the middle, and the limiting balls 21 at both ends of the contraction column 20 move into the fixed column a23. When the support column 19 is lowered, the height of the support column 18 can be adjusted according to the height of the sewage pipe 17. The hollow block 24 is fixed around the fixed column a23, and then the button b25 is fixed inside the hollow block 24 so that the stabilizing plate 26 outside the fixing button b25 can be limited inside the hollow block 24. The rotating button b27 is fixed at the bottom of the stabilizing plate 26, and then the limiting plate 28 is fixed outside the rotating button b27. The limiting plate 28 and the connecting plate 30 are fixed together with the fixed column b29. The connecting plate 30 is then fixed outside the fixed column a23 to form a fixation, preventing the support column 18 from collapsing due to the excessive weight of the sewage pipe 17 during the lifting process.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
