METHOD AND APPARATUS FOR EVAPORATING MULTI-COMPONENT LIQUIDS

摘要

AN ATOMIZER (10) ATOMIZES A MULTI-COMPONENT LIQUID FROM A RESERVOIR (20) INTO A CLOUD (14) COMPRISING SMALL DROPLETS (38) WHICH ARE EJECTED INTO THE ATMOSPHERE TO A CERTAIN HEIGHT AND ALLOWED TO FALL TOWARD A SURFACE (12). ESSENTIALLY COMPLETE EVAPORATION IS ASSURED BY MAINTAINING THE SIZE OF THE DROPLETS, THE LIQUID'S COMPONENT VAPOR PRESSURES AND THE HEIGHT THROUGH WHICH THE DROPLETS FALL ACCORDING TO A PREDETERMINED RELATIONSHIP. ALSO, THE SUITABILITY OF A LIQUID FOR EVAPORATION IN A VIBRATING PLATE ATOMIZER IS DETERMINED BY MEASURING THE RATE OF SIZE DECREASE AND THE SURFACE TENSION OF A PENDANT DROP OF THE LIQUID AFTER A PREDETERMINED AMOUNT OF THE LIQUID HAS EVAPORATED FROM THE DROP.FIG.3
