Abstract

The invention discloses an oxygen preheater which comprises a dimethyl ether combustion chamber, a heat exchange cavity and oxygen pipelines. Dimethyl ether is combusted in the dimethyl ether combustion chamber to generate heat; the heat exchange cavity is communicated with the dimethyl ether combustion chamber; the oxygen pipelines penetrate the heat exchange cavity, and oxygen in the oxygen pipelines is heated in the heat exchange cavity by the heat generated in the dimethyl ether combustion chamber. The oxygen preheater in an embodiment of the invention has the advantages that the oxygen preheater is provided with the dimethyl ether combustion chamber, the oxygen in the oxygen pipelines is heated by the heat generated when the dimethyl ether is combusted, the dimethyl ether is flammable and is good in combustion performance and high in heat efficiency, and residues and black smoke can be prevented in combustion procedures; carbon is rarely deposited on the oxygen pipelines, heat transmission is hardly affected, capital and labor investment for a soot blowing system and maintenance workload can be reduced, and environments are further protected on the basis that a preheating effect and the manufacturing cost of the oxygen preheater are guaranteed.

Description

technical field [0001] The invention relates to the technical field of metallurgy, and more specifically, relates to an oxygen preheater for preheating oxygen. 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 pol...
