A boiling chlorination system without sieve plate

Abstract

The invention discloses a fluidizing chlorination system without a sieve plate. The fluidizing chlorination system without the sieve plate comprises a chlorination furnace, a double-drum dust collector, a cyclone dust collector and a leaching device which are sequentially connected with one another; a front-stage dust collection drum and a rear-stage dust collection drum with one higher and the other lower are arranged at the upper part of the double-drum dust collector; the lower parts of the front-stage dust collection drum and the rear-stage dust collection drum are provided with a conical bottom together to be connected with a slag collection tank through an electric control valve; the bottom of the slag collection tank is connected with a slag receiving tank through an electric control valve; a cruciform four-way vertical tube short connection is arranged on the top of the chlorination furnace and is connected with the double-drum dust collector through a cross tube short connection; and the inside diameter of the cross tube short connection is above two thirds of that of a hearth of the chlorination furnace. According to the fluidizing chlorination system without the sieve plate, improved fluidizing chlorination furnaces without the sieve plates cannot have the phenomena of passage blockage and the like when all using domestic high-titanium slag raw materials, and thus the chlorination production efficiency is improved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of crude titanium tetrachloride production, in particular to a sieveless boiling chlorination system. Background technique [0002] At present, the industrial production of crude titanium tetrachloride generally adopts boiling chlorination and molten salt chlorination. Domestic boiling chlorination systems include ¢800, ¢1200, ¢1600, ¢2400, ¢2800, ¢3600 and other furnace types. With the development of technology, domestic enterprises have introduced and applied foreign large-scale chlorination technology and equipment to Improve product output and quality, such as the ¢3000 and ¢4000 fluidized chlorination furnaces in the United States and Japan. Since most foreign fluidized chlorination technologies use rutile (TiO2 content ≥ 95%, strict particle size requirements) as raw materials, the chlorination furnace and collection The aisle connection structure used between the dust collectors is relatively thin (s...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of pipe blockage between the chlorination furnace and the dust collector in the prior art, the present invention provides a sieve-free boiling chlorination system, which can realize the use of all imported sieve-free boiling chlorination furnaces. High-titanium slag raw materials do not cause aisle blockage, thereby improving chlorination production efficiency and reducing production costs
