MIXER OF SUBSTANCES CHEMICALLY REACTED WITH EACH OTHER Russian patent published in 1998 - IPC

FIELD: mixers of substances chemically reacted with each other; may be used in regulated highly efficient mixing of reagents entering into reaction to form new substance which is a product of reaction of initial substances; may be used in chemical and pharmaceutical industries in capacity of mixers of reactors of various purposes. SUBSTANCE: mixer consists of cylindrical chamber in the form of sleeve with inlet of one reagent. Located along the axis of the inlet is conoid-helicoid from hollow plate of aerodynamic profile with turns overlapping one another up to full overlapping of slotted nozzle by surface of next turn from hollow of turn along the edge of previous turn, and hollow of turns from hollow plate is connected with inlet of the second reagent. Conoid-helicoid is located with the help of bellows with screw mechanism for varying the height of bellows. With supply of reagents under preset pressure through inlets into chamber and hollow of plate of turns of conoid-helicoid, jets of reagent from chamber between turns of conoid-helicoid flow out of suck, in compliance with velocities and pressure of reagents, the jets of reagent from slotted nozzles supplied to hollow of plate of turns of conoid-helicoid. Jets form vortex inside hollow of conoid-helicoid to provide conditions of mixing and contact of reagents over large area of surfaces of spiral jets and vortexes. As height of conoid-helicod may be varied with the help of screw mechanism for varying the height of bellows, i.e. variation of relative position of turn of conoid-helicoid, it ensures smooth regulation of parameters of reagents, high quality of mixing and increased efficiency of reaction process. EFFECT: higher efficiency. 2 dwg
