Toroidal vortex vacuum cleaner centrifugal dust separator

A centrifugal separation system comprising:

• fluid delivery means for providing a fluid flow;
• a separation chamber for separating matter from said fluid flow;
• a collector for collecting said separated matter;
• an inner tube and an outer tube, said inner tube and outer tube forming an annular duct;
• and
• flow straightening vanes provided within said annular duct to straighten said fluid flow.

A centrifugal separation system comprising:

• fluid delivery means for providing a fluid flow;
• a separation chamber for separating matter from said fluid flow;
• a collector for collecting said separated matter;
• an inner tube and an outer tube, said inner tube and said outer tube forming an annular duct, said annular duct ending in a toroidal vortex nozzle.

A centrifugal separation system comprising:

• fluid delivery means for providing a fluid flow;
• a separation chamber for separating from said fluid flow;
• a collector for collecting said matter;
• an opening in the wall of said separation chamber, said opening leading into said collector;
• an outer tube coupled to said separation chamber;
• and
• an inner tube located inside said outer tube, said inner tube and said outer tube being coaxial, wherein the gap between said inner tube and said outer tube forms an annular duct.
