| 简介 |
Proposed useful model relates to the field of technology of inorganic substances, in particular, to industrial sections of (offices, peredelam , complexes, installations) for deactivation and decontamination of radioactive wastes, formed at perchloric processing technology loparite kontsenratov , containing oxides of niobium, tantalum, titanium, rare-earth, and impurities also iron, aluminium, up to 0.6% thorium, to 0.1% uranium and child products their decay. -The proposed utility model- "industrial section" is simplification of equipment technology deactivation and decontaminating liquid radioactive wastes, formed at perchloric processing technology loparite concentrate. Technical result, which can be obtained at implementation of the proposed utility model, consists in reduction of number of operations, performed deactivation of and in decrease of the quantity of reagents and their flow rate for neutralization of and deactivation of radioactive salt solutions SOF and shop obmyvochnykh water. Or problem is solved with achievement of higher than the said technical result prelagaemym "industrial section for decontamination and decontamination of radioactive waste perchloric processing technology loparite concentrate", including reactor for neutralization of pulp from dissolving ("hydro wash") exhausted salt reflux filter melt (SOF) chlorination process loparite concentrate in salt khloratorakh (further "solutions SOF "); reactors-converter of shop obmyvochnykh water, formed in shop on various processes of the process of processing loparite concentrate; tank with stirrer for preparation of solution hydro ksida of sodium, connected through metering with reactors-converters solutions SOF and shop obmyvochnykh water; two filter-press- FP for isolating from pulp radioactive oksigidratnykh sediments (FP -1)-and sediments, containing rare, dissipated and rare-earth metals (FP -2); drying chamber and prokalochnuyu furnace, equipped with unloading device and system of dust collection; collecting reservoir decontaminated solutions and shop obmyvochnykh water. New in proposed technical solution is, that "industrial section of" has additionally collecting tanks-reclaimers for solutions/pulps from "hydro wash" waste melts SOF and shop obmyvochnykh water, reactors-converter are equipped with heating devices, (made mainly in the form of vertically installed supply pipe in lower zone of reactor steam), in each reactor-neutralizer placed rod with electrodes ph meters, having mating with locking-control valves, installed on supply line solution of hydro ksida of sodium from metering in reactors of-converter, output mother solutions after isolation from pulp radioactive oksigidratnykh sediments on filter-press FP -1 is directed into tanks-reclaimers shop obmyvochnykh water and reactor-neutralizer shop obmyvochnykh water. |
