DEVICE FOR EXTRACTION PROCESSING OF URANIUM-CONTAINING SOLUTIONS OF USED NUCLEAR FUEL Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to extraction technology for recovering, purification, and concentration of elements in radiochemistry and other branches of industry. Device for extraction processing of uraniun-containing solutions of used nuclear fuel has multistage extractor and multistage reextractor involved in extraction cycle. Each stage of them is made up of mixing and settling chambers which are provided with pipe unions for inflow and outflow of water and organic phases. Device is additionally provided with extractor and reextractor of second cycle. Settling chambers of first cycle reextractor stages are provided with additional pipe unions for discharge of water phase with units for regulation of its flow rate. EFFECT: higher efficiency. 2 dwg
