INSTALLATION FOR PREPARING SPONGE TITANIUM Russian patent published in 1997 - IPC

FIELD: chemical engineering. SUBSTANCE: installation includes reduction apparatus consisting of retort-type reactor with spherical bottom, tightly dipped cover with central fitting to introduce titanium tetrachloride, magnesium, argon, and for evacuation of reactor, sheet-shaped false bottom mounted on central annular support, and drain appliance made in the form of drain pipe with rod closing means and a level. Installation also includes separation apparatus consisting of retort-condenser with cooler in the form of shell with water distributor, heat screen with inner shell, and fusible plug. The latter apparatus is installed on reduction apparatus. The point of invention consists in introduction of (i) additional annular supports on spherical bottom of retort-reactor installed concentrically with central annular support and (ii) a barrier positioned radially between central annular support and those additional supports and crossing the latter in their overflow apertures thereby forming drain channel. Further, drain appliance includes branch pipe with slot where level with screen is inserted. Heat screen is installed above the cover and its inner shell is made in the form of truncated cone facing the cover with its great base. Cooler bears a ring welded to upper part of shell and doors disposed in plane of crossing of heat screen top and shall. EFFECT: improved structure. 10 cl, 4 dwg
