An improved wet electrostatic precipitator (10) includes several flat collector electrodes (12) and flat discharge electrodes (14) respectively arranged between the collector electrodes. Water or another suitable rinse liquid is distributed over the operative surfaces of the collector electrodes by a liquid distribution arrangement comprising several tubular distributor members (60), each member including uniformly spaced, tubular overflow nozzles (62 and 63) that project vertically upwardly and that are individually adjustable to provide for uniform flow. The end overflow nozzles (63) that are adjacent the respective inlets (64) have closed lower ends. Each end nozzle further has a circular inlet aperture or bore (94) in its tubular wall, and each is oriented so that the aperture generally faces toward the associated distributor member inlet. The construction and orientation of the end nozzles assures adequate flow from the turbulent flow region of the distributor members, thereby avoiding dry spots and the resultant sparking that tends to occur at any dry spot. |
