Problems solved by technology

The continuous acid hydrolysis reactor is rectangular, although the volume is large, but the reactants only occupy a part of the reactor space, and it is square, there are many dead corners with uneven stirring, and the layout and solid-phase junction are prone to occur during use. Scar sclerosis
Due to the large volume, the release of acid gas is difficult to control, and the reactor and external heating, or cooling is difficult to achieve

Embodiment 1

[0019] like figure 1 As shown, the application provides a novel continuous acidolysis reactor, the reactant, such as the mixture of sulfuric acid and titanium concentrate, enters the continuous acidolysis reactor from the feed port, and under the agitation of the spiral stirrer, the reactant is in the Acid hydrolysis reaction occurs in the reactor, and the reaction product is discharged out of the reactor at a certain speed. Holes can be set at the top of the continuous acidolysis reactor, and part of the acid gas can be discharged from these holes. The discharged acid gas can be introduced into the acid gas treatment system to prevent the acid gas from leaking to the surrounding area.

[0020] The reaction time of the reactants in the continuous acidolysis reactor is determined by the length of the helical agitator and the continuous acidolysis reactor. The calculation shows that under the condition that the reaction time is set to 1 hour, a continuous acidolysis reactor wi...

Abstract

The invention discloses a reactor, particularly discloses the reactor for producing a titanium sulphate compound by process intensified continuous acidolysis reaction, and belongs to the technical field of metallurgical production equipment design and manufacture. The invention provides the reactor for producing the titanium sulphate compound by the process intensified continuous acidolysis reaction, which can remarkably reduce a dead angle of the reaction and reduce the scarring hardening rate of a solid phase in a process. The reactor comprises a stirrer and a reactor body which contains a reaction accommodating cavity; the reaction accommodating cavity is of a cylindrical structure which is placed horizontally.

Description

technical field [0001] The invention relates to a reactor, in particular to a reactor used for process intensified continuous acidolysis reaction to produce titanium sulfate, and belongs to the technical field of design and manufacture of metallurgical production equipment. Background technique [0002] The sulfuric acid method is one of the most important methods for the production of titanium dioxide today, and acid hydrolysis is a key process in the production of titanium dioxide by the sulfuric acid method. During this process, titanium concentrate and concentrated sulfuric acid react chemically at high temperature to generate soluble titanium sulfate and the like. The acid hydrolysis process can adopt batch or continuous acid hydrolysis technology. Some enterprises have adopted the continuous acid hydrolysis process. The core of the continuous acid hydrolysis process technology is a rectangular continuous acid hydrolysis reactor with a spiral agitator. The uniform pr...
