The invention relates to the field of titanium-containing blast furnace equipment, in particular to a titanium-containing blast furnace slag chlorination device capable of improving the TiC chlorination rate on the basis of ensuring a chlorination reaction kinetic condition and the chlorination efficiency of carbide slag so as to realize rapid, efficient and economical fluidizing chlorination treatment of the carbide slag. The system comprises a feeding system, a fluidizing chlorination furnace, a cyclone dust collection system and a titanium tetrachloride collection system which are sequentially communicated, wherein the fluidizing chlorination furnace is internally and sequentially divided into a first chlorination unit, a second chlorination unit and a third chlorination unit which arecommunicated with one another, and the first chlorination unit is communicated with a fluidizing chlorination furnace inlet of the fluidizing chlorination furnace; a first purging inlet, a second purging inlet and a third purging inlet are correspondingly formed in the bottoms of the first chlorination unit, the second chlorination unit and the third chlorination unit respectively. The titanium-containing blast furnace slag chlorination device disclosed by the invention is particularly suitable for the chlorination process of the titanium-containing blast furnace slag.
Description
technical field [0001] The invention relates to the field of titanium-containing blast furnace equipment, in particular to a titanium-containing blast furnace slag chlorination device. Background technique [0002] The reserves of vanadium-titanium magnetite are very rich in the world, and the reserves in my country are among the best, and the reserves in Panxi area reach 10 billion tons, and the total reserves of titanium resources rank first in the country. Vanadium-titanium magnetite is a multi-element symbiotic ore, which contains 30% to 34% iron (in the form of iron oxide in the ore), and is mainly used as raw material for iron, vanadium and titanium. At present, in the production of titanium-containing blast furnaces, the chlorination operation is basically stable and the production capacity has been achieved, but the Ti chlorination efficiency is low, and it is difficult to stably reach the design level, which seriously affects the Ti utilization efficiency and affect...
