| 简介 |
The claimed invention relates to inorganic chemistry, in particular to devices for chemical leaching of non-ferrous, rare and noble metals, and can be used at enterprises, processing of technogenic raw material, as a rule, with low content of target components, in particular dezaktivirovannye catalysts of various production processes of chemical and petrochemical profile, and also waste automobile catalysts.
Device for extracting useful components perkolyatsionnym leaching characterized in that consists of body, made in the form of vertically installed column, consisting of two shells - lower (2), provided with branch pipe for feeding of leaching solution (3), and upper (1) with branch pipe for output of productive solution (5) and with installed inside it airlift (4), the shell are connected between each other flanges, between which there is false bottom with net (6) with cell size is less than the minimum grain size processed raw material, the height of the lower shell (2) does not exceed 10% of height of upper shell (1).
The technical result consists in NII to increase the concentration of target components in productive solution and, respectively, reduction of volume of solutions, requiring utilization of. |
