A kind of device for preparing titanium hydroxide solution

Abstract

The invention relates to a device for making a titanium hydroxide solution. The device comprises a storage tank (1) for storing titanium source solution raw materials, wherein the storage tank is connected with a first buffer tank (3) through a first pipeline (2); the first buffer tank is connected with a reaction kettle (5) through a second pipeline (4); the reaction kettle is filled with pure water (20); the reaction kettle is connected with an alkali liquor storage tank (7) through a third pipeline (6); the reaction kettle is also connected with a second buffer tank (9) through a fourth pipeline (8); the second buffer tank is connected with a vacuum pump (11) through a fifth pipeline (10). The device for making the titanium hydroxide solution has the advantages that: the device solves acid mist generated in a hydrolytic process of a titanium source solution such as titanium tetrachloride or titanyl sulfate, and also avoids leakage of a reaction solution; by effectively controlling the internal temperature of the kettle, the vacuum degree of the vacuum pump and the operation of each valve, the safe operation of preparing the titanium hydroxide solution from the titanium source solution such as the titanium tetrachloride or the titanyl sulfate by hydrolysis is achieved.

Description

technical field [0001] The invention relates to the technical field of titanium oxychloride production, in particular to a device for preparing titanium hydroxide solution. 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 or ti...
