PRODUCTION PROCESS COMPARTMENT FOR DECONTAMINATION OF RADIOACTIVE SOLUTIONS AND WASTE WATER

Proposed useful model relates to the field of metallurgy of rare, scattered and radioactive metals, in particular, to hydro metallurgical methods of processing of polymetallic wastes, containing radioactive metals, -natural radionuclides : thorium and its decay products. Invention can be used in processing, decontamination and deactivation of liquid radioactive wastes (RAO) processes chlorination loparite and/or elimination of zircon concentrates, containing th -232 and child its decay products (ra -228, ra -224), and also rare-earth, fe, al, ti, zr, nb, the, ca, mg, na, to and others. in particular from solutions from hydro wash (dissolution) spent salt melts (melts, sublimates and T. u.) and waste obmyvochnykh shop water, formed at daily harvesting promploshchadok , equipment, pipelines, pumps and T. u ., containing diffusion nnoe amount of radionuclides and requiring decontamination and decontamination. -Of proposed technical solution is prevention of contamination of working places radioactive dust and creation of radiation-safe labor conditions for service personnel. Technical result, which can be obtained at application of utility model, consists in provision of trapping and of utilization of radioactive dust after baking and at unloading radioactive sediment from prokalochnoi furnace. Production process compartment for processing and deactivation of radioactive solutions and waste water, for example, waste in process of loparite concentrate chlorination, turn reactor for neutralization of pulp from dissolving of exhausted salt reflux filter melt (SOF) salt of chlorinator, bakdezaktivator , tanks-batchers barium chloride solution and sulfuric acid for deactivation pulp from SOF , filter-press-i for separation of hydrate-sulfate precipitation from decontaminated chloride solutions, tank with stirrer for preparing alkali solution (NaOH), connected through tank-batcher and flowmeter with reactors-converters salt solutions and shop obmyvochnykh waste water, branch pipe lower drain reactor-neutralizer shop obmyvochnykh water is directed in filter-press-ii for separation of sediment sum of hydro ksidov metals from waste water, arriving in tanks-collectors, the outlet of trough filter press is directed into drying chamber and then in prokalochnuyu furnace. Novelty is, that after prokalochnoi furnace are additionally unloading device and exhaust umbrella with fan, connected with vodooroshaemym scrubber with movable nozzle, placed between two fixed-secured horizontal partitions having over the entire surface of holes, diameter of which is 0.5-0.9 conditional diameter movable elements of nozzle-area of holes in partitions is 30-70% from their total area, and ratio of internal diameter of scrubber to the height of the movable nozzle is equal to 1 : (1-5), branch pipe lower drain scrubber is connected with circulation tank, the outlet of which has connection with irrigating device, located above surface of movable nozzle scrubber and reactor-neutralizer shop obmyvochnykh water, and also filter-press for displacement of radioactive sediment, sprinkler scrubber, Besides are also connected with tank-collector decontaminated waste water.
