  • Modular electrostatic precipitator system
    Patent number: 6576046
    Abstract: A modular two-stage electrostatic precipitator for extracting airborne particles includes individual ionizer/collector cell modules having integrated power supplies and diagnostic systems. The cell modules are adapted to be joined blindly to one another in end-to-end nested relation through nestable end plates and in a series circuit utilizing floating electrical connectors. The module end plates provide self-correction in misalignment during a blind connection and provide sealed end plate cavities for the power supply and electrical connections. The diagnostic system provides detection for any open system circuit and/or short circuit condition and allows for trouble shooting on an individual cell module basis.
    Type: Grant
