The stirring shaft of the continuous acidolysis reactor can uniformly stir the acid-ore mixture and the waste acid through the double blades, so that the phenomenon of poor local reaction caused by poor mixing is reduced; the solid-phase substances in the continuous acidolysis reactor have no caking phenomenon, are uniformly distributed in a powder state, are relatively loose and have good dissolving effect; the acidolysis reaction is good, and the acidolysis rate is obviously improved. Reference 2, application No.: CN201510261342, name of the invention: the acidolysis method for titanium dioxide production by sulfuric acid process and its equipment are characterized by that in the raw ore pulverizing section the titanium concentrate pulverized to 200 meshes and completely passed through is directly mixed with 98% sulfuric acid, the mixed mineral acid is fed into acidolysis tank by means of slurry pump, and a certain quantity of waste acid is added, and the diluted 98% concentrated sulfuric acid can release heat to initiate acidolysis reaction, and said process has the following characteristics: 1. 98 percent of sulfuric acid is directly mixed with the titanium concentrate, so that an acid preparation process in an acidolysis tank area is omitted, and energy consumption is saved; 2. the crushing of the titanium concentrate is controlled to be completely passed through 200 meshes, while the crushing of the traditional process needs to be carried out until the residual of 320 meshes is less than 1%, so that the production capacity of the ball mill is improved; 3. a pneumatic conveying system is not needed, and the conveying is changed into slurry pump conveying, so that the environmental pollution caused by pneumatic conveying is improved; 4. 98 percent of sulfuric acid is diluted by 20 percent of waste sulfuric acid, and the dilution heat of the sulfuric acid is utilized to initiate reaction, so that the heat energy is better utilized, and the using amount of steam is reduced. 5. The process is particularly suitable for use in conjunction with continuous acidolysis. The structural features of the comparison documents 1 and 2 are different from those of the present application.
