Definitions

  • At least one of the said parallel walls can rotate freely and concentrically with the rotor and that a ring of blades is mounted perpendicular to the surface of said wall and substantially at its periphery, the said blades being bent backward with respect to the direction of rotation of the driven rotor so as to cooperate with the fluid vanes, said blades being interconnected over their entire fronts by a wire mesh screen which bounds the discharge of the compressed gaseous medium.
  • the invention relates to a centrifugal fluid vanes compressor for compressing a gaseous medium.
  • a driven rotor provided with jet channels to which fluid is supplied forms between two fixed, parallel walls, fluid vanes bent backward, by means of which in the same way as at a centrifugal compressor provided with metal blades a gaseous medium can be compressed.
  • the vanes may also be bent so far backward, before they reach the moment of disintegration that they block the passage and render any further compressing of the gaseous medium impossible. Consequently from this it follows that above a certain diameter the fluid vanes are no longer useful and vanish. As a rule this fluid still contains a large amount of kinetic energy, which is lost therewith, too.
  • the discharge of the compressed gaseous medium is effected at the diameter where the fluid vanes will no longer be active.
  • Another object of the invention is to provide an improved centrifugal fluid vanes compressor having means to recover the excess of fluid energy at that diameter.
  • one or both of the parallel walls are arranged to rotate freely and concentrically with the rotor and alongside their peripheries are provided with a ring of blades and the compressed gaseous medium is discharged laterally within the said ring of blades.
  • a very large part of the excess energy at that diameter still present in the fluid vanes is drawn from the fluid by means of the ring of blades, the speed of the wall or walls acting as a secondary rotor possibly being much lower than the speed of the driven primary rotor.
  • Still another object of the invention is to provide an improved centrifugal fluid vanes compressor having means to improve the separation of fluid and compressed gaseous medium.
  • the fronts of the blades are interconnected by a wire mesh screen, giving an efficient partition for a lateral discharge of the gaseous medium.
  • this screen constitutes only a slight obstruction, while a fluid film sealing the wire mesh screen will always be present, causing the gaseous medium that is to be discharged laterally, and the velocity of which at that diameter being more tangential directed than that of the liquid, still more to be forced to flow past the wire mesh screen.
  • the separation of the gaseous medium and the fluid can still be improved by choosing the blade-height of the blades on the wall larger than the height of the fluid vanes.
  • any fluid still being present in the gaseous medium in the bend of the gas discharge gets into the wire mesh screen after all and is flung into the water discharge by the rotating ring of blades.
  • An additional advantage of the rotating wall is that the fluid remaining thereupon by the friction with the fluid vanes, is rapidly discharged by centrifugal effect.
  • IG. 1 IS a cross section of an embodiment.
  • FIG. 2 is a view taken through the line lI-ll of FIG. 1.
  • a driven rotor 2 is provided mounted on a hollow shaft 3, provided with a cogwheel 4, which is driven by an electromotor 6 via a cogwheel 5.
  • Rotor 2 has been provided with blades 7 for the suction of a gaseous medium out of feed 8 and with jet channels 9 for the fluid forming the fluid vanes, for instance water, which is supplied through hollow shaft 3 with the aid of a feedline l0 and a pump 11.
  • This pump has been connected to a casing 12, to which the fluid from the compressor is recycled.
  • a rotatable wall with its shaft 14 freely rotatable around the shaft 3, said wall 13 bounding the space for the fluid vanes.
  • a cogwheel 19 or the like is fixed for power recuperation.
  • blades 15 are located near the periphery of the wall 13 and are radially disposed from the effective compressing section of the fluid vanes. Blades 15 over their entire fronts are interconnected by a wire mesh screen 16. This wire mesh screen is bounding lateral discharge 17 for the gaseous medium, which is discharged from the compressor via an outlet 18 to be connected to a duct or the like.
  • the fluid is discharged to casing 12 alongside the inner periphery 20 of the space in which the fluid vanes are formed.
  • a centrifugal fluid vanes compressor for compressing a gaseous medium, comprising a driven rotor having jet channels to which fluid is supplied means for rotating said rotor, a pair of spaced parallel walls disposed near said jet channels perpendicularly with respect to the rotational axis of said rotor, said jet channels upon rotation of said rotor.
  • liquid vanes effecting a compressive action upon the gaseous medium between said parallel walls, one of said parallel walls being arranged to rotate freely and concentrically with said rotor with one of its planar surfaces facing toward said rotor being provided with a ring of blades mounted perpendicularly to and near the periphery of said planar surface, said blades being interconnected by a wire mesh screen over their entire fronts which face toward said rotor, said screen bounding the discharge of said gaseous medium.
