Method of and means for hydrodynamic mixing

Claim 1

A method of attaining an intimate mixture of a plurality of fluent substances in a continuous flow-through passage having an entry end and a discharge end, and comprising: combining said plurality of fluent substances at said entry end in a continuously flowing stream filling said flow through passage under substantial hydrodynamic pressure; subjecting said stream in said passage to turbulence and substantial dispersion and mixing effect from a series of adjacent alternating radially inwardly tapering relatively short frustoconical turbulence surfaces providing acceleration and radially outwardly flaring relatively longer frustoconical turbulence surfaces providing gradual dispersion; effecting abrupt turbulent transition of the stream from each of said surfaces to the next of said surfaces in the series; influencing the stream continuously between the entry end and the discharge end by one of gradual expansion and dispersion from the outwardly flaring surfaces, relatively more rapid acceleration and restriction from the inwardly flaring surfaces, and abrupt transition between expansion and restriction; thereby attaining progressively more thorough dispersion and mixing of said substances in the continuously flowing stream from said entry end to said discharge end of said passage; and discharging the thus treated stream from said discharge end of the passage to receiving means.
