Abstract

The invention relates to the field of zirconium oxychloride production devices, in particular to a device and a method for producing zirconium oxychloride with a boiling chlorination process. The device comprises a chlorination furnace, a multi-stage cooling device and a tail gas treatment device, wherein the chlorination furnace, the multi-stage cooling device and the tail gas treatment device are connected through a pipe from left to right sequentially; the chlorination furnace is used for boiling chlorination reaction; the multi-stage cooling device is used for separating high-purity zirconium tetrachloride, silicon tetrachloride and titanium tetrachloride; the tail gas treatment device is used for treating tail gas. The invention aims to provide the device and the method for producing zirconium oxychloride with the boiling chlorination process. to solve the problems that an existing device and method for producing zirconium oxychloride with the boiling chlorination process are low in production efficiency and poor in product quality and pollute the environment easily.

Description

technical field [0001] The invention relates to the field of zirconium oxychloride production devices, in particular to a zirconium oxychloride production device and method for boiling chlorination. Background technique [0002] The boiling chlorination method of zirconium oxychloride needs to use chlorine gas, zircon sand (zirconium silicate), petroleum coke, metal silicon (or silicon carbide or a mixture of the two) as raw materials, in a chlorination furnace under the conditions of 900℃-1200℃ The reaction occurs to generate zirconium tetrachloride and silicon tetrachloride, the silicon tetrachloride is purified as a by-product, and the zirconium tetrachloride reacts with water to generate zirconium oxychloride and hydrochloric acid. [0003] ZrSiO4+4C+4Cl2→ZrCl4+SiCl4+4CO [0004] ZrSiO4+2C+4Cl2→ZrCl4+SiCl4+2CO2 [0005] Si+2Cl2→SiCl4 [0006] SiC+2Cl2→SiCl4+C [0007] ZrCl4+9H2O→ZrOCl2·8H2O+2HCl [0008] The following technical problems exist in the existing zirconi...
