Potassium fluotitanate manufacture and device background

A potassium fluotitanate (K2TiF6) manufacture process comprises the following steps:

• A. providing titanium ferrum powder to a first reaction furnace and adding HF and peracetic acid solution to concurrently react with the titanium ferrum powder sufficiently to manufacture H2TiF6 and so as to oxidize Fe2+ into Fe3+ so as to inhibit production of FeTiF6 according to a reaction
• TiO2(FeO,Fe2O3)+HF+H2O+CH3CO2OH→H2TiF6+H3FeF6+CH3COOH+H2O+O2↑
• to form a mixed product solution,
• B. filtrating the mixed product solution of step A and adding the resulting filtrated product solution to a second reaction furnace and allowing the filtrated product solution to cool and then, after the H2TiF6 cools off, adding potassium chloride (KCl) solution to react with the filtrated product solution to manufacture potassium fluotitanate (K2TiF6) according to a reaction H2TiF6+2KCl→K2TiF6+2HCl, wherein the potassium fluotitanate (K2TiF6) is removed by centrifuge dripping filtrating;
• and
• C. adding K2CO3 solution to a remaining H3FeF6+H2O+HCl solution remained after the centrifuge dripping filtrating of step B to a third reaction furnace and react with the remaining solution and controlling the pH value according to a reaction
• H3FeF6+K2CO3+HCl+H2O→Fe(OH)3+KCl+KF+H2O,
• wherein the element Fe is removed by a form of Fe(OH)3 flocculent precipitate and the potassium chloride (KCl) is recycled.
