The invention discloses a titanium tetrachloride preheater, which comprises a dimethyl ether combustion chamber, a heat exchange chamber and a titanium tetrachloride pipeline, wherein dimethyl ether burns in the dimethyl ether combustion chamber to generate heat; the heat exchange chamber is communicated with the dimethyl ether combustion chamber; the titanium tetrachloride pipeline penetrates through the heat exchange chamber, and in the heat exchange chamber, the heat generated in the dimethyl ether combustion chamber is used for heating the titanium tetrachloride in the titanium tetrachloride pipeline. According to the titanium tetrachloride preheater disclosed by the embodiment of the invention, the heat generated by the titanium tetrachloride is used for pre-heating the titanium tetrachloride in the titanium tetrachloride pipeline, the dimethyl ether is combustible, good in combustion performance and high in heat efficiency, the residue and black smoke are avoided during combustion, in addition, and less carbon is accumulated on the titanium tetrachloride pipeline and hardly affects the transmission of the heat, so that bankroll and manpower investment in an ash blowing system and overall workload is reduced, and on the basis of ensuring the preheating effect and the manufacturing cost of the titanium tetrachloride preheater, the environment is protected.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to a titanium tetrachloride preheater for preheating titanium tetrachloride. Background technique [0002] The existing production of titanium dioxide mainly includes sulfuric acid method and chlorination method. The sulfuric acid method is suitable for the production of anatase titanium dioxide, and the chlorination method is suitable for the production of high-grade rutile coating titanium dioxide, accounting for more than 56% of the production capacity. %. The trend of the titanium dioxide industry in the world today is that the chloride titanium dioxide continues to develop, and the sulfuric acid titanium dioxide is gradually shrinking and eliminated. Compared with the world's advanced level, my country's titanium dioxide industry is still dominated by the sulfuric acid process titanium dioxide with small scale, low output, high cost, unstable product quality and serious environmental...
