Description

Technical Field

[0001] The present invention relates to the technical field of separation devices, and in particular to a high-precision oil-water-gas three-phase multi-stage separation device and a separation method thereof. Background Art

[0002] The oil-water-gas three-phase separation device is a separation device used to separate oil, water and gas and make them flow in different directions. The separation means of traditional oil-water-gas separation equipment are simple and the separation accuracy is low. Therefore, it is necessary to use a variety of means to improve the separation accuracy of oil, water and gas.

[0003] The defects of existing oil-water-gas separation equipment are: 1. Prior art JP2011084676A discloses an oil-water separator, an oil-water separation system, an oil-water separation method and a water reuse method using the oil-water separation method. The technology does not have a structure for multi-stage separation of oil, water and gas, and the oil-water separation method has low accuracy. Therefore, a high-precision oil-water-gas three-phase multi-stage separation device that can perform multi-stage separation of oil, water and gas with high separation accuracy is needed to solve this problem.

[0004] 2. Prior art JP2004154626A discloses an oil-water separator and an oil-water separation method. This technology can only clean the inside of the separator by flushing with water. It is difficult to clean the oil stains adhering to the internal components of the separator by flushing alone. Therefore, a high-precision oil-water-gas three-phase multi-stage separation device is needed to shake off the oil stains adhering to the internal components of the separator to solve this problem.

[0005] 3. Prior art JP2007000715A discloses an oil-water separation method and device. When flushing the internal components of the separator, the oil stains on the components in the upper space inside the separator are not easily exposed to the cleaning liquid, which results in the cleaning liquid being unable to effectively remove the impurities in the upper space inside the separator. Therefore, a high-precision oil-water-gas three-phase multi-stage separation device is needed to solve this problem, which can rotate the components in the upper space inside the separator to the bottom for flushing.

[0006] 4. Prior art CN112174357B discloses a highly efficient oil-water separation device. This technology does not have a structure for cleaning the oil and impurities on the surface of the liquid distribution components inside the separator. The distributor and the distribution components are usually porous. When there is oil on the surface of the distributor or the distribution components, the oil can easily enter the holes of the distributor or the distribution components, and the oil inside the distributor or the distribution components cannot be effectively discharged, thereby causing the distributor or the distribution components to be blocked. Therefore, a high-precision oil-water-gas three-phase multi-stage separation device that can clean the oil on the surface of the distributor or the distribution components is needed to solve this problem.

The controller 40 can receive the signals of the gas-liquid level meter 18, the gas-liquid level meter 29, and the oil-water interface meter 10, and can control the electric telescopic rod 37. The tube body 14 can drive the corrugated plate layer 16, the inclined plate layer 17, the wire mesh filler 218, the coalescing filler 19 and the inclined plate layer 20 to rotate by rotating, so that the corrugated plate layer 16, the inclined plate layer 17, the wire mesh filler 218, the coalescing filler 19 and the inclined plate layer 20 can be immersed in the cleaning water in turn. The corrugated plate layer 16 is a corrugated plate structure with a large interlayer spacing, and its main purpose is to separate the oil from the corrugated plate layer 16. The water two-phase mixed fluid is initially separated and rectified. The inclined plate layer 17 is an inclined plate structure with a small interlayer spacing. Its main purpose is to achieve the initial separation of the gas in the oil-water-gas three-phase from the other two-phase liquids. The wire mesh filler 2 18 is a filler section woven from a fiber mesh. The fiber material is stainless steel and non-metallic materials such as polytetrafluoroethylene, polypropylene, and glass fiber. Suitable fiber materials are selected according to different gas properties. This section of fiber material is woven into a filler structure with a smaller porosity, which can effectively remove micro-droplets in the gas. The coalescing filler 19 is a filler woven from fiber materials, in which the fiber material is woven according to the oil to be separated. Stainless steel fibers, non-metallic fibers, etc. can be selected for the properties of the water two-phase. Under the action of the fibers, the dispersed phase droplets in the fluid change their movement direction to collide and coalesce, or adhere to the fiber surface to wet and coalesce, and grow into large droplets. The inclined plate layer 20 is composed of multiple inclined plates with intervals, which can effectively reduce the sedimentation distance of the generated large droplets, so that the large droplets can gather to form a liquid film more quickly, thereby realizing the separation of the oil and water phases. The separated oil and water two-phase fluid is stratified after a long sedimentation section, in which the oil phase flows over the baffle 39 and gathers behind the baffle 39, and the water phase is stored in front of the baffle 39.
