| description | The invention discloses a method for purifying and crystallizing acidolysis titaniferous solution, belonging to the technical field of acidolysis of titanium dioxide. According to the invention, a tubular filter is adopted for filtration, perlite is adopted as a filter aid, and the temperature of titaniferous solution feed liquid entering the tubular filter is 50-65 DEG C. By improving the tubular filter and filtering operation steps, the problem that filtering effect is poor due to crystallization and the like is solved; efficiency is improved by 56% compared with the efficiency of a plate-and-frame filter press in the prior art; and in terms of an annual production amount of 150,000 tons of titanium dioxide and under the condition that a filtering area is 450 m , the tubular filter can meet the production requirement of the annual production amount of 150,000 tons of titanium dioxide while the plate-and-frame filter press can only realize the annual production amount of 60, 000 to 80,000 tons of titanium di |
