REACTOR INSTALLATION Russian patent published in 2005 - IPC

FIELD: equipment and methods of fluorine processing of titanium-containing raw materials.

SUBSTANCE: the invention is pertaining to the field of equipment and methods of fluorine processing of titanium-containing raw materials, for example, ilmenite concentrates at production of titanium dioxide. The reactor installation contains the reactor coupled with the sources of reactants, which through a discharge assembly is connected with apparatuses of the subsequent processing of the reaction products. At that as the sources of the reactants they use a hopper - for a solid titanium-containing material, for example, ilmenite, and the source of ammonium fluoride. The discharge assembly contains a filtrate outlet, a slurry outlet and a gas outlet. At that the gas outlet of the reactor is fused to an ammonia feeder, the reactor filtrate outlet is fused to the first screen, a filtrate outlet of which is coupled to the second screen, the filtrate outlet of which is coupled to the cavity of a hydrolysis reactor, the outlet of which is in turn coupled to the third screen, the slurry outlet of which is coupled to the dryer-dispenser, the slurry outlet of which is coupled to the charging assembly of the reactor of pyrohydrolysis, the outlet of which is coupled to a container for storage of a satin white. At that the gas outlets of the second screen, the dryer-dispenser, the third screen and the reactor of pyrohydrolysis are coupled to the source of ammonium fluoride. Besides the ammonia feeder is coupled to the second screen and to the cavity of the reactor of hydrolysis. At that the source of ammonium fluoride is additionally coupled to the cavity of the reactor of hydrolysis. Besides the slurry outlets of the reactor and the first screen are coupled to the container for storage of the slurry. At that the cavity of the reactor of pyrohydrolysis is coupled to the source of steam through the steam conduits. The invention allows to improve reliability and serviceability of the installation at usage of the highly-corrosive fluorine-containing materials during processing of titanium-containing raw material with production of white pigment, to ensure the high completeness of utilization of the raw materials, the high yield and whiteness of the product, and to simplify of the process of production.

EFFECT: the invention ensures improved reliability and serviceability of the installation at highly-corrosive fluorine-containing materials use in titanium-containing raw material processing, production of white pigment, high yield and whiteness of the product, simplified process.
