POLYMERIZER Russian patent published in 1997 - IPC

FIELD: rubber industry. SUBSTANCE: polymerizer applicable for butyl rubber synthesis contains vertical cylindrical casing with process connecting pipes. Inside the casing, shaft with stacked blade stirrers is coaxially and heat-exchanger tube bundles are peripherally disposed. The bundles are separated into sectors and have tube boards and tube divisions. Lower tube boards of bundles are positioned at the level of lower stirrer, and tube divisions at the levels of overlying stirrers. Tube divisions in interspaces between sectors may have holes. Catalyst introduction connecting pipe may be provided with catalyst introduction pipe with its open end located in annular space between bundles and the stirrer second from below. Catalyst introduction pipe can be disposed at an angle to axis of casing, its open end being directed downward. EFFECT: improved design. 4 cl, 3 dwg
