Copper wire tower having supporting device used for removing vanadium impurity in titanium tetrachloride

Abstract

The present invention provides a copper wire tower with supporting device. It is composed of tower top, tower body, supporting device and tower bottom, and can be used for removing vanadium impurity from titanium tetrachloride. Said invention also provides the concrete structure of above-mentioned every portion, and working principle of said copper wire tower and its operation method.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal smelting, in particular to a copper wire tower with a support device for removing vanadium impurities in titanium tetrachloride. Background technique [0002] The commonly used copper wire tower is composed of the tower top, the tower body, the tower bottom and the steam pipe arranged on the tower top, the copper wire ball feeding pipe, the steam interface and the reflux interface arranged on the tower bottom. The tower top and the tower body, the tower body and the tower bottom are respectively passed through concave and convex flanges, covered with gaskets and connected into one body by bolts. [0003] When working, put the copper wire ball into the tower through the copper ball feeding pipe. After use, the copper wire ball is easily invalidated by the impurities and chemical reaction products brought by the titanium tetrachloride vapor, so it must be rinsed with water. , and then pic...

AI Technical Summary

Problems solved by technology

The copper wire ball will fall rapidly after being soaked in water. When the friction force between the material in the tower and the inner wall of the tower is not enough to support the copper wire ball, the copper wire ball will fall into the sieve plate which is difficult to support at the bottom of the tower, deforming the sieve plate , causing the pressure of several tons of copper wire balls to act on the lift car under the tower or crush the lift car to death or cause the lift car to be derailed by a sudden impact, which is extremely poor in safety

At the same time, due to the splash of the falling copper wire ball, it is easy to damage the cleaning pool set under the tower, resulting in high maintenance costs

When the copper wire ball falls into the cleaning tank for washing outside the tower, the titanium tetrachloride covered on it will immediately hydrolyze and release heat after meeting air and water. The molecular formula of its chemical reaction is: TiCl 4 +2H 2 O=TiO 2 +4HCl, thus forming a large amount of acid mist, seriously polluting the environment
