Apparatus-technological scheme of tin cans scrap recycling with obtaining technical products

Abstract

The article is devoted to the study of reducing the technogenic load on the environment due to the integrated processing of household metal scrap. A waste-free, resource saving, and environmentally safe method is proposed for extracting technical products from tin cans scrap – iron (III) oxide, tin (II) complex, suitable for further use, a mixture of ammonium and sodium nitrates as fertilizer for agriculture. As a result of theoretical and experimental studies, the direction of cans scrap recycling was selected with an assessment of the parameters and factors affecting the reagent process of scrap disposal. To verify the proposed method for can scrap processing in experimental studies, the reagent method and physical modeling were used together. The processes of the reagent can scrap recycling were studied in a laboratory installation. The results of studies on the reagent can scrap processing with the individual component allocation in the form of their derivatives are presented. A block diagram and a hardware-technological scheme for scrap processing with the receipt of technical products have been developed. The possibility of processing other metal-containing wastes according to the proposed scheme is shown.
