Gas-liquid separation device

A gas-liquid separation device comprising:

• a body that has a cylindrical structure and defines a central portion configured to receive mixed fluid, the body defining an inner diameter decreasing as the body extends longitudinally outward along a central axis of the body from the central portion to opposite ends of the body, wherein the body has minimum inner diameter parts at the opposite ends thereof;
• a pair of gas discharge pipes respectively disposed at the opposite ends of the body and configured to discharge, to an exterior of the body, gas separated from the mixed fluid in an interior of the body;
• and
• a pair of liquid discharge pipes respectively disposed at the opposite ends of the body and configured to discharge liquid to the exterior of the body based on the gas having been separated the mixed fluid,
• wherein the pair of liquid discharge pipes are disposed at circumferential sides of the minimum inner diameter parts of the body, respectively, each of the pair of liquid discharge pipes defining a predetermined angle with respect to a corresponding one of the pair of gas discharge pipes,
• wherein a respective gas discharge pipe of the pair of gas discharge pipes has (i) a first end defining a predetermined gap between an outer circumferential surface of the respective gas discharge pipe and an inner circumferential surface of a corresponding one of the minimum inner diameter parts and (ii) a second end that extends from the first end and defines only one opening at the central portion of the body,
• wherein each of the pair of liquid discharge pipes protrudes outward from the corresponding one of the minimum inner diameter parts to thereby prevent the gas separated from the mixed fluid from being mixed with the liquid flowing toward a respective liquid discharge pipe of the pair of liquid discharge pipes,
• wherein the minimum inner diameter parts and the respective gas discharge pipe extend parallel to the central axis such that a width of the predetermined gap is maintained from the first end of the respective gas discharge pipe to an inner end of each of the minimum inner diameter parts, and
• wherein the predetermined gap is connected to the interior of the body and configured to communicate at least a portion of the mixed fluid with the interior of the body.
