Swirl mixing device

A mixing device comprising a cylindrical container having a closed end and an exhaust;

• a first collar securely fixed within said container, said collar having a central opening;
• a first fluid injection chamber defined between said closed end and said first collar;
• first means for injecting a first fluid into said first injection chamber in a direction tangential to a circle of radius greater than that of said opening but less than that of said chamber, and with a given angular momentum;
• a second collar securely fixed within said container between said first collar and said exhaust, said second collar having a central opening;
• a second fluid injection chamber defined between said first collar and said second collar;
• and second means for injecting a second fluid into said second chamber with an angular momentum opposite to that of said first fluid and in a direction tangential to a circle of radius greater than that of said opening in said second collar but less than that of said second chamber.

A device for mixing fluids comprising a substantially cylindrical container having a closed end and an exhaust;

• at least two fluid injection chambers within said container, a first one of said chambers being located between said closed end and the second one of said chambers;
• first passage means for fluid flow from said first to said second chamber;
• second passage means for fluid flow from said second chamber to said exhaust;
• first means for injecting a first fluid into said first injection chamber in a direction tangential to a circle of radius greater than that of said first passage means but less than that of said first chamber, and with a given angular momentum;
• and second means for injecting a second fluid into said second injection chamber with an angular momentum in the opposite direction to that of said first fluid and in a direction tangential to a circle of radius greater than that of said second passage means but less than that of said second chamber.

A device for mixing fluids comprising:

• a substantially cylindrical container having a closed end and an exhaust;
• at least two fluid injection chambers within said container, a first one of said chambers being located between said closed end and the second one of said chamber;
• first passage means for fluid flow from said first to said second chamber;
• second passage means for fluid flow from said second chamber to said exhaust;
• first means for injecting a first fluid into said first injection chamber in a direction tangential to a circle of radius smaller than that of said container, and with a given angular momentum;
• and second means for injecting a second fluid into said second injection chamber in a direction tangential to a circle of radius smaller than that of said container with an angular momentum in the opposite rotational direction to that of said first fluid.
