CHECKERWORK FOR MASS-AND-HEAT EXCHANGE APPARATUS Russian patent published in 2000 - IPC

Abstract RU 2158631 C1

FIELD: chemical, petrochemical and gas branches of industry. SUBSTANCE: checkerwork is hollow cylinder with agitating elements on its external surface made in form of side rectangular branches with square holes and recesses in cylinder with rectangular elements bent inside the latter perpendicularly to side rectangular branches. Checker- work provides for enhanced efficiency of heat-and-mass exchange processes due to enlargement and development of contact surface, volumetric growth of density at nonuniform packing and to interpenetration of elements and turns of surface. EFFECT: enhanced efficiency. 2 dwg
