Abstract

The invention relates to a titanium dioxide production method, in particular to a decomposing titanium liquor purification method and a filter for the same during titanium dioxide production. The decomposing titanium liquor purification method includes the steps of precipitating decomposing titanium liquor, and filtering precipitated decomposing titanium liquor through a tubular filter so as to obtain purified decomposing titanium liquor. The decomposing titanium liquor purification method is time saving, labor saving and capable of reducing production cost and improving product performance and is widely applicable.

Description

technical field [0001] The invention relates to a production method of titanium dioxide, in particular to a purification method of acidolysis titanium solution in the production of titanium dioxide. Background technique [0002] Titanium dioxide is a white pigment widely used in coatings, chemical fibers, rubber, enamel, ceramics, plastics, papermaking, printing inks, electronic ceramics, glass, welding rods, cosmetics and other industries. The existing preparation of titanium dioxide has the chloride method and the sulfuric acid method: [0003] The chlorination method is to mix rutile or high-titanium slag powder with coke, and then perform high-temperature chlorination to generate titanium tetrachloride, which is oxidized at high temperature to generate titanium dioxide, and then filtered, washed, dried, and crushed to obtain titanium dioxide products. The process is short, the production capacity is easy to expand, the degree of continuous automation is high, the energy...
