A washing and drying integrated device and method for titanium sponge

Abstract

The invention discloses a sponge titanium washing and drying integrated device and method, which belongs to the technical field of metallurgical production and solves the problem in the prior art that the chlorine element in the sponge titanium exceeds the standard. The technical scheme of the present invention is: comprising a reactor (5), the top of the reactor (5) is provided with a rinse water inlet (2), and the rinse water inlet (2) is connected with a rinse water system, the The bottom of the reactor (5) is provided with a rinse water outlet (9), and the reactor (5) is provided with several layers of grids (7) for holding titanium sponge, and the reactor (5) is provided with a vacuum system An interface (3), the vacuum system interface (3) is connected with a vacuum system. The invention can wash and dry the sponge titanium, thereby reducing the content of chlorine element in the sponge titanium, improving the grade of the sponge titanium, reusing discarded reactors, reducing investment, saving costs, and improving enterprise benefits. The invention is suitable for removing water-soluble impurities in sponge titanium.

Description

technical field [0001] The invention belongs to the technical field of metallurgical production, and in particular relates to an integrated device and method for washing and drying sponge titanium. Background technique [0002] Magnesium thermal reduction method is used to produce sponge titanium, and vacuum distillation is usually used to remove magnesium chloride and elemental magnesium chloride in sponge titanium. The magnesium chloride in the titanium sponge cannot be removed, which in turn causes the chlorine element in the titanium sponge to exceed the standard, which seriously affects the quality of the titanium sponge. In addition, in the production process of sponge titanium, if the liquid magnesium refining process is not properly controlled, electrolytes such as calcium chloride with a boiling point higher than magnesium chloride will be introduced, and the high-boiling impurities cannot be removed by distillation, resulting in excessive chlorine in the sponge tit...

AI Technical Summary

Problems solved by technology

[0002] In the production of sponge titanium by magnesia thermal reduction, vacuum distillation is usually used to remove magnesium chloride and elemental magnesium chloride in sponge titanium, but during the distillation process, due to the operation process, 2%-4% of the distillation channels will be blocked, resulting in Magnesium chloride in sponge titanium cannot be removed, which will cause the chlorine element in sponge titanium products to exceed the standard, seriously affecting the quality grade of sponge titanium

In addition, in the production process of sponge titanium, if the liquid magnesium refining process is not properly controlled, electrolytes such as calcium chloride with a boiling point higher than magnesium chloride will be introduced, and high-boiling impurities cannot be removed by distillation, resulting in excessive chlorine in the sponge titanium product, making the sponge Titanium is downgraded due to chlorine, and even becomes an unqualified substandard product
