A series furnace device for the reduction distillation production of sponge titanium

Abstract

The invention relates to a series furnace device for reducing distillation and production of titanium sponge. The series furnace device mainly comprises a condenser and a reactor, wherein the structures of the condenser and the reactor are the same, and the condenser and the reactor are both assembled by a tank body and a big cover. During a distilling process, the tank body of the condenser, the big cover of the condenser, the big cover of the reactor and the tank body of the reactor are connected in an I-shape from top to bottom. An upper flange of the reactor big cover and an upper flange of the condenser big cover are connected through a rubber mat and a bolt; a magnesium plug is arranged inside a central tube of the reactor big cover with the effect of opening the distilling process; a gas-guide tube is arranged between the central tubes of two big covers for pressing the magnesium plug before distilling and playing the steam flow guiding effect after distilling; and an upper-cooling type cooling water jacket is adopted for indirect cooling. By adopting the series furnace device, the heat separation of the reactor and the condenser can be realized after finishing distilling, the detached condenser is immediately put into the furnace, the afterheat can be sufficiently utilized and the furnace takeup time can be reduced. The assembly and the separation of the reactor and the condenser are simple and the labor intensity is low.

Description

technical field [0001] The invention belongs to the field of sponge titanium production, and in particular relates to a series furnace device used for the reduction distillation production of sponge titanium. Background technique [0002] The reduction distillation process of sponge titanium is an important link in the production of sponge titanium from titanium tetrachloride, and is the key to the quality and cost control of sponge titanium. In a closed reactor composed of a tank and a large cover, magnesium is added at one time, and then titanium tetrachloride is continuously added during the reduction process, and the liquid magnesium and the vaporized titanium tetrachloride are on the surface of the liquid magnesium. The reaction produces liquid magnesium chloride (which sinks to the bottom of the reactor and is intermittently drained) and solid, spongy (capillary-rich) titanium. After the reduction, under vacuum and high temperature, the magnesium and magnesium chlorid...

Problems solved by technology

[0005] my country's titanium sponge quality, comprehensive cost and other aspects are not at a disadvantage in the world, but the power consumption per unit product of reduction distillation is far behind the world's advanced level.
