  • Patent number: 9009944
    Abstract: Wet electrostatic precipitator (WESP) collector tube bundles are formed by a procedure in which strips of conductive material are corrugated, intended abutting surfaces of the corrugated strips are abraded, adhesive is applied to the abraded surfaces, multiple ones of the corrugated strips are assembled with corrugation in abutting relationship, and outer panels are assembled with the resulting hexagonal tube bundle.

  • Publication number: 20130133518
    Abstract: An electrostatic precipitator, particularly a WESP, comprising an array of collector tubes and a like array of separately powered discharge electrodes provided in the form of pairs of rods extending within each of the collector tubes. The pairs of rods are provided in the form of a first length rod having a terminal end, the first length rod powered by a first power source, and an axially opposed, second length rod having a terminal end, the second length rod powered by a second power source, wherein each first length discharge electrode rod, of a pair of rods, extends from an inlet of the electrostatic precipitator into a respect e collector tube and each second length discharge electrode rod, of the same pair of rods, extends from an outlet of the electrostatic precipitator into the same, respect e collector tube such that the respective terminal ends of the pairs of discharge electrode rods are spaced apart, thereby defining a gap therebetween.

  • Publication number: 20080307964
    Abstract: Contaminant laden gas streams from wood product dryer operations, and other sources, are purified. The gas stream first is saturated with moisture by contacting the gas stream with fine liquid droplets which entrain particulates. The gas stream then is subjected to a plurality of separate particulate and liquid droplet removal steps before a droplet-free gas stream having substantially reduced particulate contaminant levels is passed to a burner for removal of volatile organic compounds from the gas stream.

  • Patent number: 7402196
    Abstract: A mist elimination device in the form of a hood for the removal of moisture from a gas stream treated by a WESP includes a series of gutters on the outer surface of the hood to trap liquid droplets and direct the moisture to channels to drain to the lower region of a housing. Gutters are also provided on the interior surface of the hood to catch liquid droplets carried by the gas stream into the interior of the hood.
