REACTOR Russian patent published in 2005 - IPC

FIELD: fluoride methods of processing of titanium-containing raw materials.

SUBSTANCE: the invention is pertaining to the fluoride methods of processing of titanium-containing raw materials, for example, ilmenite concentrates at production of titanium dioxide. The reactor contains a body including a tubular wall with a bottom and a cover. The driving shaft with stirrers is located in a cavity of the reactor. The heat-supply unit is placed outside the cavity of the reactor. The reactor has a loading unit and an unloading unit. The surface of the cavity of the body of the reactor is made out of magnesium; the surfaces of the details located in the cavity of the reactor is made out of a material resistant to action of solutions of fluoride-containing reactants. Components of the body are connected hermetically and the loading unit and unloading unit are made with a capability to be sealed. The cover of the reactor is supplied with a gas outlet line branch pipe supplied with the shutoff valves. In the bottom of the reactor there is an unloading gate. The invention allows to improve reliability and serviceability of the reactor in operations with usage of a highly aggressive reactant, excludes losses of quality of the final product.

EFFECT: the invention ensures improved reliability and serviceability of the reactor in operations with usage of a highly aggressive reactant, excludes losses of quality of the final product.
