Abstract

The invention provides a reaction kettle. The reaction kettle comprises a kettle cover and a kettle body; a feed port is formed in the kettle cover, and a discharge port is formed in the bottom of thekettle body; the reaction kettle further comprises a filtering device and a circulating device, the filtering device is arranged at the bottom of an inner cavity of the kettle body, and the circulating device is arranged outside the reaction kettle and connected with the kettle cover and the kettle body through pipelines respectively. According to the reaction kettle, the problems of violent reaction, static electricity generation, pressure building and the like caused by the fact that a conventional reaction kettle cannot well control the generation process of activated aluminum oxide can besolved, potential safety hazards in production are eliminated, the service life of the reaction kettle is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the field of chemical equipment, in particular, the invention relates to a reaction kettle. Background technique [0002] Activated alumina is generated by reacting metal aluminum with insufficient amount of hydrochloric acid. Its chemical reaction equation is: 2Al + (6-n) HCl + nH 2 O=Al 2 (OH)nCl 6-n +3H 2 ↑, the reaction mechanism is complex, which mainly includes four main reactions: acid dissolution, hydrolysis, bridging polymerization and polymer hydrolysis. The above four reactions are actually crossed, and the intermediate products produced are also very complicated. In the reaction In the process, the reaction conditions need to be well controlled in order to obtain activated alumina products suitable for use as binders. [0003] The main equipment of the activated alumina reaction process is an enamel reaction kettle. In the process of preparing activated alumina, first add a certain amount of chemical water, th...
