Sponge titanium reduction distillation reactor and production technique thereof

Abstract

The invention relates to a sponge titanium reduction distillation reactor which is formed by connecting a tank body and a large cover through a flange rubber cushion and a bolt set, wherein the tank body comprises a bottom plate, a sieve plate, a magnesium chloride discharge casing, a tank body flange and a waist-type cylinder; the large cover comprises a magnesium chloride discharge pipe, a thermal insulation layer, an internal heating device, a large cover upper flange, a large cover lower flange, a central pipe, a charging casing 1, a short cylinder and a charging casing 2; the integral reactor is in a stereoscopic waist circular structure; and the bottom plate is a sloping plate positioned on the lowest part of the whole reactor, and is matched with the waist-type cylinder to form an open stereoscopic waist-type tank body. The integral effective width of the reactor is 1.2-1.5 meters, the height is 1.5-2.5 times of the width, and the length is 2-3 times of the width. The reactor for producing sponge titanium can change the sponge titanium structure, solve the problem of compactness, greatly enhance the overall charging rate, simplify the distillation process and greatly shorten the period.

Description

technical field [0001] The invention belongs to the field of sponge titanium production, and in particular relates to a sponge titanium reduction distillation reaction device and a production process. Background technique [0002] After 60 years of development, the production process of titanium sponge has gradually become unified: the Krall method (magnesium method) and reduction-distillation joint production, and the equipment and production capacity are developing towards large-scale. [0003] 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 the reaction device, magnesium is added at one time, and then titanium tetrachloride is added continuously during the reduction process, and the liquid magnesium and the vaporized titanium tetrachloride react on the surface of liquid magnesium to generate liquid magnesium chl...

AI Technical Summary

Problems solved by technology

At present, the country chooses simple equipment and large-scale production capacity, that is, increasing the diameter and height of the reaction device to reduce the power consumption per unit of product; and this large-scale equipment will make the heat dissipation conditions of the product worse, the height of the titanium lump will increase, and the single-furnace product If the furnace takes too long, the center and bottom of the titanium lump will be dense and the machinability will be deteriorated.
