Description

Technical Field

[0001] The utility model relates to the field of three-phase separation equipment, in particular to an oil, gas and water three-phase separation device. Background Art

[0002] After oil is extracted, it is necessary to separate the three phases of oil, gas and water. The three-phase separation device is an indispensable equipment for crude oil separation. The mixed liquid encounters the inlet diverter, so that the liquid and gas are initially separated. The gas carrying a large number of droplets is further separated by the coalescing plate, making it become dry gas and discharged from the outlet. Under the action of gravity, due to the difference in density between oil and water, free water sinks to the bottom of the container, and the oil floats on the surface and climbs over the oil-water baffle into the oil chamber. The separated free water is discharged through the drain valve operated by the oil-water interface regulator.

[0003] The existing three-phase separation device is unable to separate solid impurities in the oil when performing oil-water separation, resulting in the separated oil still containing impurities and being unable to meet actual usage requirements. In addition, the internal structure of the separation device is relatively complex, and it is inconvenient to disassemble and clean, which is not conducive to subsequent maintenance and cleaning.
