Background

At present, the titanium sponge produced by industrial production at home and abroad adopts a Kloer method, and the titanium sponge is produced by an inverted U-shaped combination method developed in the furnace type large-scale direction. The titanium sponge reduction production is that liquid titanium tetrachloride is continuously introduced into a closed hot-end reactor to react with liquid magnesium to generate titanium sponge and magnesium chloride, after the reduction is finished, a reactor is arranged at a cold-end system to collect magnesium chloride distilled from the hot end and a small amount of magnesium, and a pure titanium sponge product is obtained after the distillation is finished. However, during distillation, the phenomenon of blocking the vacuum channel is frequently generated, namely, a mixed condensate of magnesium chloride and magnesium is formed at the lower part of a large cover vertical pipe at the cold end. When the vacuum channel is blocked, the large blind plate on the three-way vertical pipe on the large cover needs to be detached to dredge the vacuum channel, but the large blind plate has large mass, the lifting difficulty of an operator is high, an overhead traveling crane needs to be lifted off, the overhead traveling crane needs to be lifted during installation, the running time of the overhead traveling crane is occupied, and particularly when a plurality of production systems are arranged in a factory building, the overhead traveling crane is busy; when the overhead travelling crane is hoisted without time, the overhead travelling crane is manually disassembled for driving the production time, the disassembly of the large blind plate is carried out at high temperature, the scalding is easy, and the potential safety hazard of manual operation is large; the blind plate has no heat preservation performance, and the whole distillation production consumes a large amount of electric energy; because of the big pipe diameter of tee bend riser, keep malleation in the reducing furnace when must inject a large amount of argon gas ability, prevent that the product from being polluted by the admit air, not only taken away the heat in the reducing furnace, still caused the argon gas use amount to increase, also increased manufacturing cost.
