Problems solved by technology

[0003] Although the existing premixing device has a premixing system with high acidolysis efficiency, the structure is complex, the cost is high, and it is uneconomical for the enterprise. At the same time, some premixing systems also have the problem of slow acidolysis rate during the acidolysis process. Therefore, it is necessary to invent a premixing device with simple structure and high acid hydrolysis rate to solve the problem

Abstract

The invention discloses a premixing device used for continuous acidolysis to produce titanium dioxide. The premixing device comprises a premixing tank, a mineral powder input port is arranged at top of the premixing tank, a mineral powder silo is outwardly connected with the mineral powder input port, the mineral powder input port is inwardly connected with a mineral powder tube, the upper part ofthe premixing tank is provided with a spraying mechanism, the spraying mechanism comprises a plurality of ring bodies having pipelines and having different diameters, and the plurality of ring bodiesare coaxial, and the plurality of the ring bodies are mutually communicated, each of the ring bodies is provided with a plurality of spray holes, the lower part of the premixing tank is provided withtwo stirring mechanisms arranged up and down, and the stirring directions between the two stirring mechanisms are opposite to each other. The premixing device is capable of uniformly mixing the reactants and increasing the acidolysis efficiency.

Description

technical field [0001] The invention relates to the technical field of continuous acidolysis reaction equipment for titanium dioxide, in particular to a premixing device for continuous acidolysis production of titanium dioxide. Background technique [0002] At present, there are two processes for industrial production of titanium dioxide: the chloride method and the sulfuric acid method. The technology of the chlorination method is quite complicated, and requires high equipment materials and automatic control levels. At present, only a few countries have mastered this technology. The technology of research and development is difficult, and the investment cost of equipment is high. Therefore, the sulfuric acid method is still basically used in my country. Production of titanium dioxide. The main process of sulfuric acid production of titanium dioxide is: acid hydrolysis of ilmenite powder and concentrated sulfuric acid to produce titanyl sulfate, and then hydrolyzed to genera...
