Definitions

  • the present invention relates to pressure exchangers.
  • the leakage gas enters the low-pressure zone at a velocity of about three hundred feet per second
  • the velocity of the leakage gas entering the low-pressure zone could be reduced by increasing the working clearance at that zone but it is desirable to keep the working clearance small to control the leakage of gas from the high-pressure zone.
  • the curved portion of one surface is shaped and arranged with respect to the position at which the other surface terminates so as to take advantage of the Coanda effect. While the curved surfaces will be dimensioned to suit the particular pressure exchanger to which they are being applied, each curved surface will have a radius of curvature of not less than four times the width of the clearance defined by the surfaces.
  • FIGURES 4 and 5 are similar views to FIGURES 2 and 3, respectively, showing modifications, and
  • the height of the outlet port 8 that is the distance between its radially inner and outer surfaces, is made less thanthe height of the cells 3, that is the radial distance between the members 1 and 2.
  • the working gas flowing from a cell to the port 8 passes over a step as it enters the port.
  • the radially outer edge of the port 8 is formed with a smoothly curved surface 18 leading into the port.
  • the difference in height between the port 8 and the cells 3 is made such that the curved surface commences opposite the termination of the end-face of the member 2 which therefore does not need to be recessed.
