CARBONIZER Russian patent published in 2017 - IPC C01F7/14 C22B3/02 

FIELD: chemistry.

SUBSTANCE: invention relates to hydrochemical production equipment and can be used in the production of alumina from nephelines or low-grade bauxites using a sintering technique. Carbonizer comprises a cylindrical housing (1) with a conical bottom (2) and a cover (3), tubes (5) for feeding gas into the carbonizer and an exhaust pipe (10) for removing the exhaust gas from it, air lift (4) for agitating aluminum hydroxide suspension produced during decomposition of solutions. Pipes (5) for feeding gas into the carbonizer are positioned vertically within the housing (1), wherein their lower parts are fixed coaxially in cylinder courses (6) rigidly connected to each other and to the walls of the housing (1).

EFFECT: invention reduces power consumption.
