A production device for preparing titanium hydroxide sol

Abstract

The invention relates to a production device for preparing titanium hydroxide sol. The production device comprises a storing tank (1) which is connected with a first buffer tank (3) through a first pipeline (2), the first buffer tank is connected with a second buffer tank (5) through a second pipeline (4), the second buffer tank is connected with a vacuum pump (7) through a third pipeline (6), the first buffer tank is further connected with a reaction kettle (9) through a fourth pipeline (8), the reaction kettle is filled with pure water (20), and the reaction kettle is further connected with an alkali solution storing tank (11) through a fifth pipeline (10). The production device has the advantages that the problem that acid mist is generated in the hydrolytic process of a titanium source solution like a titanium tetrachloride solution or a titanyl sulfate solution is solved, the rate of the reaction of the titanium source solution and an alkali solution is effectively controlled, the leakage of reaction solutions is avoided, the temperature in the kettle, the vacuum degree of the vacuum pump and operation of all levels of valves are effectively controlled, and the safe production operation for preparing the titanium hydroxide sol through hydrolysis of the titanium source solution like the titanium tetrachloride solution or the titanyl sulfate solution is achieved.

Description

technical field [0001] The invention relates to the technical field of titanium hydroxide production, in particular to a production device for preparing titanium hydroxide sol. Background technique [0002] Titanium hydroxide, also known as orthotitanic acid, is an important raw material for the preparation of titanium dioxide with different crystal structures. Titanium dioxide can be prepared by different methods, including gas phase method and liquid phase method, but the liquid phase method is mainly used, such as sol-gel method. , particle method, titanium source hydrolysis method and other methods, wherein the preparation of titanium hydroxide by titanium source hydrolysis method is a common preparation method. But because of the different raw materials for hydrolysis, different equipment and processes are used. In the process of preparing titanium dioxide, the method mainly used in industry to prepare titanium hydroxide solution by hydrolyzing titanium tetrachloride o...
