  • Ultrasonic generation of a submicron aerosol mist
    Patent number: 5145113
    Abstract: An ultrasonic piezoelectric aerosol submicron mist generator is disclosed having a high-frequency, piezoelectric crystal (18) which is vibratible at a selected frequency to atomize a liquid (24) that has been evenly distributed over the crystal (18) via an annular flow control washer (28). The atomized liquid (24) forms a mist (20) thereafter received into a mixing chamber (30) wherein the mist (20) is entrained into a low pressure gas (36). The low pressure gas (36) transports the entrained mist (20) about a separator plate (32), whereby the mist (20) must change flow direction in order to exit a nozzle outlet (42) thus forcing droplets (40) larger than the desired size to separate from the low pressure gas (36) before reaching the nozzle outlet (42).
