Online dechlorination technology of chlorination process tailing slag extracted titanium
The invention discloses a processing technology of chlorination process tailing slag extracted titanium and belongs to the metallurgical field. The invention provides an online dechlorination technology of chlorination process tailing slag extracted titanium. The technology includes the following steps that firstly, the chlorination process tailing slag extracted titanium enters a beating tank through a slag discharge port of a chlorination furnace, and the temperature of the chlorination process tailing slag extracted titanium is 400-550 DEG C; secondly, the chlorination process tailing slag extracted titanium and water in the beating tank are stirred and beaten for form sizing agents, and the mass ratio of the water to the slag in the sizing agents is controlled to be 3.2-4:1; thirdly, by means of a slurry pump, the sizing agents are conveyed to a slag yard through a pipeline, and therefore integration of dechlorination and tailings conveying can be achieved; fourthly, the beaten tailing slag extracted titanium naturally settles in the slag yard till the water content of tailings is 12-20% and the chlorine ion content is lower than 0.3%; fifthly, the tailings where natural settlement is performed directly enter a rotary kiln through a belt and are calcinated for 20-40 min at the temperature of 600-700 DEG C. By means of the online dechlorination technology, the chlorine ion content of the chlorination process tailing slag extracted titanium is smaller than or equal to 0.08%.
