Liquid distributor for a wet electrostatic precipitator

In a wet electrostatic precipitator including a housing, a plurality of collector electrodes vertically mounted within the housing, a plurality of discharge electrode assemblies mounted within the housing with one electrode assembly being mounted equidistantly spaced between each pair of the collector electrodes, means adapted for applying a high voltage to the discharge electrode assemblies to form electrostatic fields between the respective pairs of collector electrodes, and a liquid distributor arrangement adapted for flushing the collector electrodes with rinse liquid, said distributor arrangement including a plurality of elongated distributor members, means supporting one of said distributor members directly over each of the collector electrodes, each distributor member being tubular and extending adjacent the top edge of the associated collector electrode and having an inlet opening for providing ingress of rinse liquid, and a plurality of tubular overflow nozzles secured projecting vertically upward at substantially uniform longitudinal spacings in each distributor member, each nozzle having an open upper end located outwardly of the associated distributor member and an inner end located within the associated distributor member, wherein the improvement comprises:

• the end overflow nozzle of each distributor member located nearest the distributor member inlet opening being closed at its lower inner end and having a flow inlet aperture defined through the tubular wall thereof at a location within the distributor member upwardly displaced from its inner end and being positioned in a directional orientation generally facing toward the inlet opening thereat of the associated distributor member.
