AUTOCLAVE Russian patent published in 2005 - IPC

Abstract RU 2266869 C2

FIELD: heat-and-mass-exchanging equipment which may be used in, for example, alumina production for heating of bauxite pulp in bauxite autoclave leaching procedures.

SUBSTANCE: autoclave for heating of bauxite pulp has vertical cylindrical housing with pulp supply branch pipe and pulp discharge branch pipe, apparatus for supplying steam into housing upper part, and circulation pipeline axially aligned with respect to housing. Steam supply apparatus is disposed outside the circulation pipeline so as to provide exit of steam therefrom below upper edge of circulation pipeline.

EFFECT: simplified construction, enhanced reliability in operation and increased efficiency owing to reduced steam pressure losses.
