Abstract

The present invention relates to an equipment for preparing titanium tetrachloride by chlorination of titanium-containing mineral and its method. The upper hole of sealed storage tank is communicated with lower hole of preparation storage tank by pipe, the lower hole of the sealed storage tank is communicated with feeding hole of screw feeder the outlet of which is connected on the feeding hole of rapid reaction fluidized bed by a pipe, said rapid reaction fluidized bed has a gas inlet communicated with a gas pipe. Said fluidized bed is communicated with a condenser, which a gas-solid cyclone separator is connected, its upper portion has a product outlet and its lower portion has a waste material outlet. Said method includes: chlorination reaction, fluidized bed reaction, cooling and gas-solid separation.

Description

technical field [0001] The invention relates to the technical field of titanium dioxide production by chlorination, in particular to a device and a method for preparing titanium tetrachloride by chlorinating titanium-containing minerals. Background technique [0002] Titanium tetrachloride produced by chlorination of titanium-containing minerals is an intermediate product in the production of titanium products such as titanium dioxide and sponge titanium by chlorination. Currently, TiCl is produced by chlorination 4 The current industrial methods mainly include molten salt chlorination and boiling chlorine. [0003] The molten salt chlorination method is to suspend finely ground titanium slag and petroleum coke in molten salt (made of KCl, NaCl, MgCl 2 , CaCl 2 etc.) medium, a method of producing titanium tetrachloride by introducing chlorine gas for chlorination. The chlorination principle is that the chlorine gas introduced is strongly mixed and stirred for the molten s...
