COMPLEX INSTALLATION FOR PRODUCTION OF SORBTION MATERIALS Russian patent published in 2018 - IPC B01J20/04 B01J20/30 C02F1/28 G21F9/04 

FIELD: technology of water and air purification.

SUBSTANCE: invention relates to complex of equipment intended for production of sorption materials for treatment and purification of liquid media contaminated with toxic and radioactive materials, mainly to extract long-lived radionuclides of cesium and strontium from high salt solutions, in particular from liquid radioactive waste. Device comprises connected in accordance with the sequence of technological process, pipelines with blocking and control valves, reactors-mixers for preparation of solutions of initial reagents, pumps for pumping water and solutions of initial reagents into a reactor for synthesis of sorption material, connected with the consumption tanks of reagents and with source of water provided with a cleaner, slurry pump to feed synthesized material into thickener, a slurry tank with nonconventional fraction of sorption material, drying box for drying and subsequent calcination of sorption material, means for its grinding and sieving. Synthesis reactor is designed as autoclave, outlet of which, through intermediate tank, is connected with thickener in form of dryck-filter, from which thickened product is transferred to drying box, and filtrate into collection tank for liquid waste. Outlet of liquid waste collector is connected with an additional inlet to synthesis reactor, additional outlet of which is connected with liquid waste collection tanks. Reactor-mixer for preparation of solution of toxic initial reagent, in particular barium chloride, is equipped with top-mounted rasterizer in form of sealed bin with self-sealing lid, equipped with safe opening of bags with dry reagent and means of irrigation of internal space of bin.

EFFECT: increase the efficiency of installation while increasing its production and environmental safety.
