  • 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
    Filed: January 28, 2016
    Date of Patent: October 27, 2020
    Assignee: Edwards Limited

  • Patent number: 9346005
    Abstract: An apparatus for treating a gas stream includes a plasma abatement device that has a reaction chamber and a plasma torch for generating a plasma stream for injection into the chamber for treating the gas stream. A first inlet conveys a gas stream into the plasma abatement device for treatment, and a second inlet, in a normal condition of the apparatus, is in flow communication with a source of reagent for conveying a reagent into the plasma device for improving the efficiency of the treatment. In a back-up condition of the apparatus, the second inlet is in flow communication with a gas stream source for conveying a gas stream into the device for treatment.
