  • Thermoelectric particle precipitator and method using same for collecting particles from fluid streams
    Patent number: 6666905
    Abstract: A thermoelectric particle precipitator for removing and collecting particles from a fluid stream. The thermoelectric particle precipitator utilizes one or more thermoelectric modules to create a temperature gradient which causes suspended particles in a fluid stream to undergo thermophoretic movement and precipitate on a surface on the cooled side of the temperature gradient. The collection surface may be a cooled surface of the thermoelectric module or a cooled surface of a thermal mass. The collected particles may be analyzed to determine their composition.
    Type: Grant
