Abstract
Closed liquid circulating systems, which have supply and return lines and a circulating pump, have a problem when gas present in the circulating liquid. A device for removing the gas by insertion in the system includes an upright main body which has an upper chamber and a lower chamber. The separating horizontal wall has a gas discharge port in the center thereof. The horizontal inlet has an integral diffuser positioned immediately inside of the lower chamber. The integral diffuser is affixed at horizontal and vertical angles to the horizontal axis of the inlet. The horizontal outlet has a vertical pipe leg positioned inside of the lower chamber so that the lower segment thereof is positioned in the lower portion of the lower chamber and that the vertical axis of the lower segment of the vertical pipe leg is aligned in the vertical axis of the upright main body. A gas vent-eliminator is positioned within the upper chamber. The liquid enters the inlet and is forced tangentially against the side of and downwardly in the lower chamber so as to form a water vortex in the lower chamber whereby the gas in the liquid is released in the form of bubbles. The lower end of the vertical pipe leg is below where the bubbles form. The gas bubbles rise into the upper chamber and are purged into the atmosphere by means of the gas vent-eliminator.
