Embodiment Construction

[0017] Combine below figure 1 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0018] The invention provides a kind of processing technique of titanium dioxide, comprises the following steps:

[0019] First, acidolyze the raw ilmenite ore with sulfuric acid solution; use a stirring tank to carry out stirring and acidolysis of the raw ilmenite ore and sulfuric acid solution, a valve is provided at the bottom of the stirring tank, and the valve is connected to a hose 1. After the valve is opened, the liquid after acidolysis Through the hose, it is sent to the filter press device for 2 lines of filter press. In the implementation process, after the ilmenite raw ore is added to the stirring tank, the stirring tank is provided with stirring blades, and under the action of the stirring blades, the ilmenite raw ore and th...

Abstract

The invention relates to preparation of titanium dioxide, in particular to a titanium dioxide processing process. The titanium dioxide processing process comprises the steps of carrying out acidolysison ferrotitanium crude ores and sulfuric acid solution; filtering and pressing a liquid after acidolysis; concentrating and filtering a filtered-pressed filter liquor to obtain a titanium liquid; andhydrolyzing, refiltering-repressing and calcining the titanium liquid to obtain the titanium dioxide. According to the titanium dioxide processing process, by using stirring, pressing-filtering, finefiltering, concentrating, filtering, hydrolyzing, refiltering-repressing and calcining processes to produce the titanium dioxide, the technological process is reasonable, and the quality of the produced titanium dioxide is high. Moreover, the gravity force of the liquid is sufficiently utilized, the energy consumption is greatly reduced, the production efficiency is enhanced, the floor space of the whole system is small, and the investment cost is reduced.

Description

technical field [0001] The invention relates to the preparation of titanium dioxide, in particular to a processing technology of titanium dioxide. Background technique [0002] In the process of producing titanium dioxide by the sulfuric acid method, the filtrate must be collected by a filter press process after the acid hydrolysis of the raw ore. The current press filter process is generally filtered by a filter press, and the filtrate must be output for fine filtration. In practice, due to the limitation of structure and process, the existing filter press has low efficiency and high energy consumption. At the same time, the collected filtrate needs to consume more energy when it is conveyed for fine filtration, so that the energy consumption of the whole process is better. , Low production efficiency. Contents of the invention [0003] In view of the above technical problems, the present invention provides a processing technology of titanium dioxide which saves energy c...
