Abstract:
1. A reactor for producing ultra fine particles comprising: a reaction chamber; a plurality of spaced porous structures located in said reaction chamber, wherein said plurality of porous structures rotate around an axis, when said reactor is under operation, and each of said plurality of porous structures comprises portions having different angular speeds relative to said axis; and a feed means for separately injecting one or more feed liquids in a direction from said axis towards said plurality of porous structures, such that said one or more feed liquids are splashed and divided by said plurality of porous structures into fine droplets, when said reactor is under operation and said one or more feed liquids are introduced into said feed means; wherein said feed means comprises two or more inlet pipes parallel to said axis, and each of said two or more inlet pipes comprises an inlet end adapted to connect to a feed liquid; a sealed end opposite to said inlet end; and a perforation part between said inlet end and said sealed end, and being surrounded by said plurality of porous structures, said perforation part being provided with a plurality of perforations along said axis facing said plurality of porous structures.
