UNIT FOR CONDUCTING REACTION OF GASEOUS REAGENTS CONTAINING SOLID PARTICLES Russian patent published in 2003 - IPC

FIELD: units for conducting reactions in tubular reactors of one of several gaseous reagents at high velocities of flow. SUBSTANCE: proposed unit used for introducing gaseous reagent at high velocity into tubular reactor includes cylindrical chamber for delivery of gaseous reagent; rear and front ends of this chamber are closed; chamber has ring-shaped hole over periphery, first ring-shaped storage chamber having external wall and at least one side wall tightly secured to external part of gaseous reagent delivery chamber; first storage chamber has ring-shaped side outlet hole and tangential inlet hole for receiving high-velocity flow of gaseous reagent containing solid particles and for making flow perform swirling; second ring-shaped storage chamber has external wall and sides; its diameter exceeds diameter of first storage chamber; it is tightly secured to external part of gaseous reagent delivery chamber; second storage chamber has ring- shaped side inlet hole tightly adjoining ring-shaped side outlet hole of first storage chamber, ring-shaped slot formed inside second storage chamber adjoining its side wall opposite to ring-shaped side inlet hole; ring-shaped slot tightly adjoins ring-shaped hole of gaseous reagent delivery chamber over entire perimeter; it extends to section close to external side wall of second storage chamber; it is provided with many blades located at distance relative to one another and secured inside ring- shaped slot for two or more radial slots inside it. EFFECT: possibility of conducting reactions at low pressure differential in reactor; avoidance of erosion caused by solid particles. 11 cl, 7 dwg
