  • Patent number: 10814336
    Abstract: Known wet electrostatic precipitators are large and inefficient. The present invention enables the production of smaller, more efficient and long lasting wet electrostatic precipitators by the addition of a central bore in the inner electrode through which a first purge flow is passed and directed into the precipitator chamber, perpendicular to the direction of flow of the gas to be treated through the chamber to urge the particulate into the water curtain. A second, larger, cleaning purge flow is also provided to disturb the water curtain such that it cleans the inner electrode of any deposited particulate.
    Type: Grant
