Technical Field

The utility model relates to a titanium tetrachloride production technical field, concretely relates to thick titanium tetrachloride filtration system.

Background

Titanium tetrachloride is a raw material for producing titanium dioxide or titanium sponge by a chlorination method, the current domestic methods for producing titanium tetrachloride mainly comprise boiling chlorination and molten salt chlorination, but the components of the obtained gaseous crude titanium tetrachloride are very complex whether the titanium tetrachloride is prepared by the boiling chlorination or the molten salt chlorination, and the gaseous crude titanium tetrachloride can be mainly divided into four types of soluble gas impurities, liquid impurities, solid impurities and insoluble solid suspended matters. Impurities in the crude titanium tetrachloride not only affect the quality of the subsequent product, but also increase the energy consumption of the subsequent refining process, and therefore must be removed.
