MIXER Russian patent published in 2004 - IPC

FIELD: chemical industry; mixers of reactors for mixing liquid and gaseous reagents.

SUBSTANCE: the invention is dealt with chemical industry, in particular, to the mixers of reactors for mixing liquid and gaseous reagents and may be used in manufacture of carbamide for production of a mix of carbon dioxide, ammonia and a recirculated solution of ammonia carbonate salts fed into a reactor of a synthesis of a carbamide. The mixer contains a cage made out of in series connected coaxial vortes chambers. The chambers have tangential inlet branch-pipes for reactants feeding and axial outlet branch-pipes. Direction of rotation of tangential streams in all chambers is the same. The axial outlet branch-pipe of each preceding chamber is inserted into the cylindrical cage of the next chamber and its inlet opening is located on a course of traffic of reactants after an inlet opening of a tangential inlet branch-pipe. The technical result is maintenance of a high degree of dispersion of the reactants in the reactor after their exit from the mixer and at their minimum dispersion in the mixer.

EFFECT: the invention ensures a high degree of dispersion of the reactants in the reactor.
