In the process of separating the three-phase stock solution through the separating means 300, the gaseous gas is first separated, and the water and the oil are in a liquid state, and the layer is formed by the difference in specific gravity. Oil with a low specific gravity is collected above the water. The oil overflows and separates from the water.

Through this process, the gas is discharged to the first outlet (400), the water is discharged to the second outlet (500), and the oil is discharged through the third outlet (600).

Meanwhile, the three-phase separator having a high thermal efficiency of the present invention is provided with a water jacket 700 for performing heat exchange with the interior of the pressure vessel 100. The water jacket 700 may be integrally coupled with the water jacket 700 so as to surround a part of the outer surface of the pressure vessel 100 and may include at least one water jacket 700. The water jacket 700 may include an inlet portion 710, The water for heat exchange is introduced through the inlet part 710 and then discharged to the outlet part 720.

The weir panel 340 is spaced apart from the separating agitator 320. The weir panel 340 is formed to a predetermined height from the bottom surface of the pressure vessel 100. The weir panel 340 preferably includes a separating agitator 320 As shown in FIG. The weir panel 340 is a smooth plate, and water or oil can not pass through the weir panel 340 directly. When the water level rises above a predetermined level, the weir panel 340 flows over the upper part of the weir panel 340.

The water and oil passing through the separating agitator 320 are separated into layers and the water is positioned in the lower layer due to the specific gravity difference and the oil forms the upper layer. That is, the weir panel 340 functions as a kind of dam, and only the oil forming the upper layer is moved beyond the weir panel 340 as the water level becomes higher, so that water and oil are completely separated.

A second outlet 500 is provided between the separating agitator 320 and the weir panel 340 to allow water to be discharged through the second outlet 500.

More preferably, a deformer 350 may be provided horizontally connected to the upper end of the weir panel 340 and extended to the mist extractor 330. A plurality of pores may be formed in the deformer 350, So that the air bubbles contained in the oil are removed.

The gas component passes through the mist extractor 330 and is directed to the first outlet 400, which may still contain moisture. And a second mist extractor 360 is installed below the first outlet 400 to separate water remaining in the gas again.

A recovery pipe 370 for treating the water separated by the second mist extractor 360 is provided and the recovery pipe 370 is directed to the space between the weir panel 340 and the separating agitator 320 So that it is mixed with the water that is stored.

More preferably, the second outflow port 500 and the third outflow port 600 may be connected to the check line 800 directed to the inlet port 200, and each of the check lines 800 may include a visible window 900, Respectively. A metering pump 810 is installed in each check line 800 to bypass some of the water and oil discharged through the second outlet 500 and the third outlet 600 to flow through the check line 800 . Water and oil flowing through the check line 800 can be confirmed through the visible window 900, thereby verifying that the separator is properly operated.

As described above, the separator according to the present invention performs heat exchange with the inside of the pressure vessel 100 through the water jacket 700 installed on the outer surface of the pressure vessel 100 in order to more efficiently separate the three-phase stock solution, The performance of the separator can be improved.

Particularly, since the water jacket 700 is installed with a wide distribution along the outer surface of the pressure vessel 100, it is possible to maximize heat exchange efficiency through a wide heat transfer area, and there is no need to provide a separate heat exchanger Can be provided.
