Abstract

The invention discloses a three-phase fluidized continuous reaction device for preparing rutile by a hydrochloric acid leaching method. The three-phase fluidized continuous reaction device comprises a fluidized reactor, a titanium concentrate feeding system, a liquid entering system and an acid solution circulation system, and also comprises a gas entering system, wherein the fluidized reactor is a gas-liquid-solid three-phase fluidized reactor and comprises a gas-liquid distribution section, a reaction section, a settlement section, and an expanding section, which are orderly arranged from bottom to top; and a titanium concentrate feeding hole, a gas feeding hole, a liquid feeding hole, an acid solution feeding hole, an overflow port and a tail gas outlet are arranged. The device disclosed by the invention is strong in material adaptability, full to stir liquid and solid, less in mother liquid amount, and short in reaction time, and can continuously produce.

Description

technical field [0001] The invention relates to a fluidized continuous reaction device for gas-liquid-solid three-phase contact used in the production process of artificial rutile prepared by a hydrochloric acid leaching method, belonging to the field of chemical machinery. Background technique [0002] Rutile is relatively pure titanium dioxide, which generally contains more than 95% titanium dioxide. It is widely used because of its excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength, and small specific gravity. However, the existing natural rutile resources are seriously in short supply, and artificial rutile is generally used instead. [0003] Artificial rutile, also known as synthetic rutile, refers to a titanium-rich raw material that is produced by separating most of the iron, calcium, magnesium and other components in titanium concentrates by chemical processing methods. The composition and structu...
