Abstract
An apparatus for degasifying a liquid medium. The apparatus comprises a chamber in which gas is removed from the liquid medium, means for conveying the liquid medium into this chamber, means for conveying the liquid medium out of the chamber, and means for reducing pressure within the chamber to separate the gas from the liquid medium. The method comprises the steps of conveying liquid medium into the chamber, reducing pressure within the chamber to separate gas from the liquid medium, and then conveying the degasified liquid medium out of the chamber.
Claims9
Apparatus for degasifying a liquid medium comprising
- a chamber in which gas is removed from the liquid medium,
- means for conveying a liquid medium into said chamber, connected with an external source of the liquid medium, and constituting means for intermittently conveying the liquid medium from the external source to said chamber,
- means for conveying the liquid out of said chamber,
- means for reducing pressure within said chamber to separate the gas from the liquid medium, comprising a piston adapted to extend into and retract out of said chamber, to thereby alter volume of the same and constituting means for intermittently reducing pressure within said chamber to a level below pressure in the external source of the liquid medium, and
- means for directing the gas separated from the liquid medium out of said chamber, comprising an outlet connected with said chamber, in which
- said pressure reducing means additionally comprise means for flexibly sealing said piston from the volume of said chamber as said piston passes into and out of said chamber, thereby altering the volume thereof and
- means for driving said piston into and out of said chamber, said driving means comprising
- two adjacent pressure chamber,
- a second piston sealingly separating said adjacent pressure chambers from one another, said second piston connected with said first piston,
- a pressure line connected with each of said adjacent pressure chambers and adapted to introduce pressure fluid into each of said adjacent pressure chambers,
- valve means disposed in said pressure line to control introduction of pressure fluid into one or the other, or into both of said pressure chambers,
- two discharge lines, each connected with a respective adjacent pressure chamber for discharging pressure fluid therefrom, and
- valve means disposed in each of said discharge lines for controlling release of pressure fluid from said respective adjacent pressure chambers.
