Turbomixer with rotating injector for mixing liquid

A fluid-medium mixer for mixing a propellant fluid and a conveyed fluid and having an impeller rotatable about an axis, said impeller comprising:

• a) a hollow shaft defining said axis and supporting the impeller on said axis;
• b) an impeller housing supported on said shaft for rotation about said axis, said housing having:
• i) a front wall extending across said axis;
• ii) a back wall axially spaced from said front wall and also extending across said axis;
• iii) a casing defining a sealed fluid-transfer chamber within said housing between said front wall and said back wall;
• c) a plurality of injectors for said fluids, said injectors having inner ends equipped with mixing nozzles and extending along injector axes to open outwardly of said housing in a cooperative manner and positioned and oriented to exert a rotational force on said impeller in response to discharge of said propellant fluid through said injectors, said mixing nozzles being in communication with said fluid-transfer chamber;
• d) a plurality of primary nozzles each operatively connected to said hollow shaft, one for each said injector, positioned to discharge propellant fluid into said injector mixing nozzles along said injector axes;
• e) pressurized fluid propellant supply means communicating with said primary nozzles to supply a propellant fluid through said hollow shaft and to each of said primary nozzles at a first and elevated pressure;
• and
• f) conveyed fluid supply means to draw said conveyed fluid into said fluid-transfer chamber at a second pressure below said first pressure by means of suction developed by said rotating impeller;
• whereby discharge of pressurized propellant through said fluid propellant supply means, said primary nozzles, said mixing nozzles and through said injectors along said injector axes causes said impeller to rotate and draws conveyed fluid from said fluid-transfer chamber and from said conveyed fluid supply means through said mixing nozzles to be mixed with said propellant and discharged through said injectors.
