POTASSIUM FLUOTITANATE MANUFACTURE AND DEVICE BACKGROUND
摘要：
The invention provides a Potassium Fluotitanate (K2TIF6) manufacture process. The Potassium Fluotitanate (K2TIF6) manufacture process includes steps: A. providing titanium ferrum powder to a reaction furnace and adding HF and peroxide solution to react with the titanium ferrum powder sufficiently to manufacture H2TiF6, B. filtrating the sufficiently mixed solution of step A and adding it to another reaction furnace, and then after the H2TiF6 cools off, adding Potassium Chloride (KCl) solution to react with the mixed solution to manufacture Potassium Fluotitanate (K2TiF6); C. adding K2CO3 solution to the remaining solution of step B and react with the remaining solution and controlling the pH value, the element Fe is recycled by a form of Fe(OH)3 flocculent precipitate and the Potassium Chloride (KCl) and KF solution are recycled. This invention has these advantages: adding peroxide to the titanium ferrum powder can oxidize Fe2+ into Fe3+ and adding K2CO3 solution to clean element Fe out by a form of Fe(OH)3 flocculent precipitate, and the hydrofluoric acid (HF) can be recycled which can realize the HF zero polluting discharge.
摘要（中）：

本发明提供了一种氟钛钾（K2TIF6）制造方法。 氟钛酸钾（K2TIF6）的制造方法包括以下步骤：A.向反应炉提供钛铁粉末，并加入HF和过氧化物溶液以充分反应钛铁粉，制备H2TiF6，B.过滤步骤A和 将其加入到另一个反应炉中，然后在H2TiF6冷却后，加入氯化钾（KCl）溶液与混合溶液反应制备氟钛酸钾（K2TiF6）; C.将K 2 CO 3溶液加入到步骤B的剩余溶液中，与剩余溶液反应并控制pH值，元素Fe通过Fe（OH）3絮状沉淀物形式再循环，并将氯化钾（KCl）和KF溶液 被回收。 本发明具有以下优点：向铁铁粉中添加过氧化物可以将Fe2 +氧化成Fe3 +，并通过Fe（OH）3絮状沉淀物形式将K2CO3溶液加入到清洁元素Fe中，氢氟酸（HF）可回收利用 可实现HF零污染排放。
