Embodiment 1
[0039] In the preparation of titanium dioxide by the sulfuric acid method, the sedimentation process is carried out as follows:
[0040] (1) Add flocculant to the flocculant allocation tank, and at the same time pass steam and stir;
[0041] (2) At the same time, inject the acid hydrolysis slurry from the acid hydrolysis process into the acid hydrolysis slurry high tank, and stir;
[0042] (3) After the acid hydrolysis slurry and flocculant are fully stirred, the acid hydrolysis slurry and flocculant are injected into the continuous thickener for mixing and settling;
[0043] (4) The supernatant obtained in step (3) is injected into the titanium clear liquid storage tank, and further supplied to the crystallization process;
[0044] (5) The intermediate drain obtained in step (3) is input to the clearing titanium solution tank, and the clearing titanium solution obtained by further precipitation can be injected into the clearing titanium solution storage tank or directly supplied to the...

The invention belongs to the technical field of mixed materials handing, and particularly relates to a sedimentation method of an acidolysis material titaniferous solution, and more particularly relates to a sedimentation method used in an acidolysis material containing sediment titanium ore without being completely reacted. In adopting a vitriol method to prepare titanium dioxide, a sedimentation process is carried out in the steps of adding a flocculating agent in a flocculating agent configuration groove, stirring the mixture after introducing steams into the groove at the same time; meanwhile, injecting acidolysis slurry from a acidolysis process into an acidolysis slurry head tank and conducting stir; injecting the acidolysis slurry and the flocculating agent into a continuous thickener after fully mixing the acidolysis slurry and the flocculating agent and conducting mixed sedimentation; injecting the obtained supernate into a pure titanium liquid storage tank so that the supernate can be further provided to a crystallization process.
Description
Technical field [0001] The invention belongs to the technical field of mixed material processing, and specifically relates to a sedimentation method of acid hydrolyzed material titanium liquid, more specifically, a sedimentation method for acid hydrolyzed material titanium liquid containing silt and incompletely reacted titanium ore. Background technique [0002] The main application areas of titanium dioxide: coatings, plastics, inks, papermaking, of which coatings account for 60%, plastics for 20%, papermaking for 14%, and others (including cosmetics, chemical fibers, electronics, ceramics, enamel, welding rods, alloys, glass, etc.) Domain) accounted for 6%. [0003] Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of reinforcing, anti-aging and filling. Adding titanium dioxide to white and colored rubber products, it is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is ...
