Abstract

The invention relates to a device and a method for preparing titanium tetrachloride by chlorination of titanium-containing minerals. The device includes: the upper port of the sealed storage tank communicates with the lower port of the preparatory storage tank through a pipeline, the lower port of the sealed storage tank communicates with the feed port of the screw feeder, and the discharge port of the screw feeder passes through a On the feeding port of the pipeline and the fast-reaction fluidized bed, an air inlet of the fast-reaction fluidized bed is connected with the gas pipeline; the fast-reaction fluidized bed is connected with a condenser, and the fast-reaction fluidized bed is connected with a cyclone gas-solid separator , the upper part has a product outlet, and the lower part has a waste material outlet. The method includes: gas-solid raw materials are chlorinated in a first-stage rapid reaction bed; the reaction gas entrains the mixture into a turbulent fluidized bed for reaction; the residue after the reaction and a small amount of unreacted material run upwards in the reaction bed to the end A first-stage reaction bed; then cooling and separation of the gas-solid mixture. Its advantages: TiCl 4 The yield is high and the purity is 99.9%, which eliminates the sticking problem and reduces environmental pollution.

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...
