METHOD FOR PREPARING HYGROSCOPIC SUBMICRONE ALKALINE METAL IODIDE AEROSOL IN ATMOSPHERE AIR Russian patent published in 2006 - IPC A61L9/14 B05B1/24 B05B5/00 

FIELD: medicine, medicinal technology.

SUBSTANCE: invention relates to physics of aerodispersed systems, namely to methods for preparing hygroscopic submicrone aerosols of alkaline metal iodides. Method for preparing hygroscopic submicrone aerosol of alkaline metal iodides in atmosphere air involves feeding atmosphere air into heated quartz cylindrical reactor with evaporating alkaline metal halide, saturation the air flow with its vapors, mixing vapor-air mixture with cold air in outlet from quartz cylindrical reactor and its cooling up to the supersaturation degree 10² and their condensation to form submicrone aerosol of alkaline metal halide. As alkaline metal halide method involves using potassium iodide, sodium iodide or their mixture. Atmosphere air is fed into heated quartz reactor with its relative moisture above 30% at temperature 10-40°C and saturated its with vapors of potassium iodide and/or sodium iodide at temperature 550-750°C with simultaneous formation of bipolar gaseous ions and saturated molecular iodine vapor. Vapor-air flow in outlet from quartz cylindrical reactor is cooled initially to temperature 150-250°C with additional coaxial flow of atmosphere air for formation of bipolar charged submicrone aerosol of potassium iodide and/or sodium iodide with addition of molecular iodine followed by cooling aerosol flow to temperature 30-50°C with simultaneous its dilution of its concentration by turbulent stirring with additional coaxial atmosphere air flow. Invention provides formation of hygroscopic bipolar charged submicrone aerosol alkaline metals iodide (KJ and/or NaJ) with addition of molecular iodine (J₂) that is stable by size and the mass concentration in atmosphere used in system for conditioning atmosphere air and creating the curative microclimate into compartments, and for providing the possibility for its using for medicinal aims for inhalation. Invention can be used in systems for conditioning air and creating the curative microclimate into compartments, and in medicine in treatment of diseases with using atmosphere air comprising hygroscopic submicrone aerosol of alkaline metals iodide.

EFFECT: improved preparing method, valuable medicinal properties of aerosol.
