| titleOfInvention | The technique that a kind of titanium dioxide hydrochloric acid residue resource recycles |
| abstract | The present invention provides the technique that a kind of titanium dioxide hydrochloric acid residue resource recycles.The technique includes：Composite filter aid preparation, hydrochloric acid waste residue modification, the depickling of modified hydrochloric acid waste residue, the calcining of a titanium dioxide blob of slag, oil-containing salt acid distillation, hydrochloric acid and separation of oil and residual kettle liquid after-treatment, the preparation process of the composite filter aid include：Polyethylene glycol, polyvinylpyrrolidone and polyvinyl alcohol are pressed 1:2:7~2:3:5 mass ratio is successively dissolved in the enamel medicine dissolving tank containing running water, obtains the composite filter aid of resistance to highly acid that mass concentration is 2%.Composite filter aid each component is nonionic organic high molecular compound in the technique of the embodiment of the present invention, without any metal ion, and composite filter aid addition is relatively low, only account for 1.5% or so of hydrochloric acid waste residue dry, decomposed substantially after high-temperature calcination, smaller to recovery titanium dioxide impurities affect, the content of titanium dioxide for determining the product after high-temperature calcination is 85%~92%, can be used as high titanium slag. |
