DEVICE FOR PRODUCING POWDER ALUMINIUM OXIDE OF HIGH PURITY Russian patent published in 2017 - IPC C01F7/42 B22F9/16 C25B1/00 

Abstract RU 2637843 C1

FIELD: chemistry.

SUBSTANCE: device contains an electrolyser for the electrolysis of aqueous solutions with the oxidation of metallic aluminium, connected by the pipeline with the reverse osmotic installation to produce source industrial water, and receiving capacity for products of oxidation. In the lower opening of the receiving container, an outlet is provided connected to the upper screen of the wash cage. The bottom screen of the rinsing separator is connected by a product supply line to the aluminium oxidation product thermal treatment unit.

EFFECT: increasing the safety of the device and reduce the content of the main impurity metals of water in aluminium oxide.
