Chlorination furnace for fine-fraction titanium-rich material and fluidizing chlorination process thereof

The invention discloses a chlorination furnace for a fine-fraction titanium-rich material and a fluidizing chlorination process thereof, and belongs to the technical field of design and manufacturingof metallurgical production equipment. Provided are a chlorination furnace for the fine-fraction titanium-rich material and the fluidizing chlorination process thereof that can effectively increase chlorination efficiency and greatly reduce chlorination loss. The chlorination furnace comprises a feeding system, a gas supply system, a titanium tetrachloride collecting system and a chlorination furnace body, and further comprises at least two groups of fluidizing chlorination reaction units with gradually deepened chlorination depth, the fluidizing chlorination reaction units sequentially arranged at the lower part of the chlorination furnace body along the chlorination direction communicate with each other by respective upper openings in an overflowing manner; the fluidizing chlorination process enables a fine-grai
