Method of and apparatus for generating mixed and atomized fluids

A fluid spouting composite nozzle unit, for generating mixed and atomized fluids from at least two fluids selected from gases, liquid and powders, comprising in combination:

• first nozzle means for effecting a first stage mixing and atomizing of the fluids;
• second nozzle means for spouting the fluids mixed and atomized by said first nozzle means toward a downstream side thereof;
• guide conduit means for guiding the fluids mixed and atomized said first nozzle means to said second nozzle means;
• fluid reflecting means positioned on the downstream side of said second nozzle means for cooperation therewith to define an outlet space in which fluid from said second nozzle means collides with fluid reflected from said reflecting means, the shape and size of said space being determined by the configurations, dimensions, and spacing of said reflecting means and said second nozzle;
• and
• means for interconnecting said first and second nozzle means, said conduit means, and said fluid reflecting means,
• wherein said first nozzle means has a conical convergent passageway, a conical divergent passageway concentrically connected to said conical convergent passageway and at least two fluid supply openings into said conical divergent passageway, and wherein said second nozzle means has a conical convergent passageway.

A fluid spouting composite nozzle unit for generating mixed and atomized fluids from at least two fluids selected from gases, liquids, and powders, comprising, in combination:

• nozzle means for receiving a first stage mixture of said fluids and spouting said mixture toward a downstream side thereof;
• and
• fluid reflecting means positioned on the downstream side of said second nozzle means for cooperation therewith to define an outlet space in which fluid from said second nozzle means collides with fluid reflected from said reflecting means, the shape and size of said space being determined by the configurations, dimensions, and spacing of said reflecting means and said second nozzle,
• wherein said fluid reflecting means comprises a substantially cylindrical element provided, at one end thereof facing said second nozzle means, with a circular cavity into which said fluids are spouted from said second nozzle means, and wherein said cylindrical element is further provided, at said one end thereof, with a flange-like projection for generating a low-pressure zone around said cylindrical element when said fluids are spouted from said second nozzle means.
