CONCENTRATOR OF MICROINGREDIENTS IN AEROSOL Russian patent published in 1997 - IPC

FIELD: spectrum analysis, applicable for concentration of substances under analysis in aerosol. SUBSTANCE: the concentrator has a three-section heating chamber consisting of first section 1 of drops breaking, second section 2 of drops evaporation and third section 3 - cyclone; the first section is furnished with annular cornice 11 located in its bottom part 10, whose top part is made in the form of a toroidal surface of revolution conjugate to interior conical surface 9 of section 1, and cooling chamber 23, liquid feed channel 24 connected jointly with capillary tube 6 - jet generator to the heating chamber for rotation of the free end of capillary tube 6 - jet generator and liquid feed channel inlet end 4 due to rotator 5, carrier gas feed channel 51, channel 34 for drainage of condensed liquid, channel 44 for discharge of aerosol. Used as the cooling chamber is an additional heating cyclone with channel 39, used to discharge the particles of aerosol dry residue, connected to the spectrum excitation source; placed at the outlet of third section 3 of the heating chamber - cyclone is a chamber - trap of coagulated aerosol drops turning in the top part to channel 32 for calcination of dry residue particles; the first (1) and second (2) sections of the heating chamber have a make-up internal heating, and the ends of capillary tube 6 - jet generator and liquid feed channel 4 are made for rotation about the axis of capillary tube 6; the top part of annular cornice 11 is made in the form of toroidal surface 12. EFFECT: enhanced efficiency. 2 cl, 1 dwg
