Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a production device for corrosion materials used for oxidation and reduction of ilmenite. Background Art

[0002] Ilmenite resources are extremely abundant in the world. my country's ilmenite resources account for about 48% of the world's titanium reserves, which are distributed in 20 provinces across the country. There are both rock sand and mineral sand, of which rock ore accounts for the majority. Rock ore is mainly distributed in the coastal areas of Guangdong, Guangxi and Hainan. Although my country is a country with a large number of titanium resources, due to the low abundance of titanium ore, the difficulty of mining, and the low level of production technology, the available titanium resources are still in short supply at this stage.

[0003] Ilmenite (FeTiO3) is a derivative structure of corundum structure, with a general TiO2 content of about 52.65% and FeO of 47.4%. At present, the utilization of ilmenite resources mainly uses sulfuric acid method and chlorination method to produce rutile, titanium dioxide and sponge titanium. The sulfuric acid method production technology uses hot concentrated sulfuric acid to decompose the selected and crushed ilmenite, and uses iron powder as a reducing agent to produce a mixed solution of titanium, divalent iron and other associated sulfates, commonly known as titanium liquid; during the oxidation and reduction process of ilmenite, the reaction materials used are corrosive, which can easily cause corrosion damage to the production equipment, thereby affecting the production efficiency of the equipment.
