Spiral-flow gas-oil-water separator

The utility model discloses a spiral-flow gas-oil-water separator, which comprises a columnar cylinder (1). A fluid input pipe (11) is tangent to the side wall of the columnar cylinder (1). The upper part of the side wall of the columnar cylinder (1) is also provided with an oil outlet pipe (13). The oil outlet pipe (13) is positioned above the fluid input pipe (11). A clapboard (2) is also arranged between the oil outlet pipe (13) and the fluid input pipe (11) in the columnar cylinder (1). The center of the clapboard (2) is provided with an oil guide pipe (3). The bottom end of the oil guide pipe (3) is positioned below the bottom of a fluid input pipe (141). And a funnel-type separator cartridge (4) is also arranged below the oil guide pipe (3) in the columnar cylinder (1). Compared with the prior art, the spiral-flow gas-oil-water separator makes the oil and the water which have small density difference capable of being separated well, and makes the gas naturally collected to the center thereof and then exhausted front the exit pipe after passing through the oil guide pipe so as to finally realize the individual separations of the gas phase, the oil phase and the water phase. The utility model has the advantages of small volume, high separation efficiency and convenient maintenance, and is suitable for various oil qualities.
