  • Patent number: 4441897
    Abstract: A wet electrostatic precipitator (10) including a plurality of removable nested collecting electrodes or plates (36) forming a repeating pattern of hexagonal collecting zones (44) throughout the precipitator (10). Each collecting plate (36) is formed with a sixty degree bend along two opposing longitudinal edges so as to allow three plates (36) to form a self-nesting Y-shaped intersection point (46). Six points (46) form a hexagonal collecting zone (44). The plates (36) are removable thereby expediting replacement. A plurality of strategically placed spray nozzles (34) provide wash fluid to the plates (36). Magnet sets (56 and 58) provide for discharge electrode (18 and 18A) alignment and rapping.
