HYDRODYNAMIC MIXER

摘要

FIELD: machine building.SUBSTANCE: mixer comprises a casing with axial and radial branch pipes for component supply, mixing elements. The axial inlet branch pipe can move back-and-forth and is made as a conical-cylindrical nozzle. A mixing element consists of a conical insert with circular grooves on its surface. The insert is located in the conical part of the mixing element casing. A deflector in the form of an indentation is provided at the end face of the insert opposite the conical-cylindrical nozzle in the centre. The mixing element casing is fitted by through channels set on concentrical circumferences. The circular grooves are connected to the first mixing chamber by channels. There shall be at least two mixing elements. The total area of the channels connecting the circular grooves to the mixing chamber amounts to (5-20)% of the area of the cross section of the circular radial gap at the inlet to the mixing element. Diameters of the concentrical circumferences on which centres of the channels provided on the end face surface of the conical insert greater base are located, are determined according to a mathematical expression.EFFECT: intensified hydrodynamic, physical-chemical and heat-and-mass exchange processes.4 cl, 3 dwg
