The electrostatic precipitator (ESP) is an effective device for industrial air pollution control. Electrostatic precipitation technology has been around for over 100 years and, within the last few decades, a push for new technology and applications of this device has been experienced. Wet ESPs (WESP) use a spray or film of water to remove collected particulate from the system. They have improved collection efficiencies over traditional ESPs in regards to collecting fine particulate, < 3µm. At Ohio University, a WESP testing facility has been developed to monitor and evaluate the efficiency of current and new technology. The pilot WESP test rig was designed with a testing chamber 4ft x 8ft x 7.5ft (w x l x h). A wash scheme was developed with flat fan nozzles and the system has the capability of reaching 100% relative humidity. Testing was performed with 2 types of discharge electrodes, stainless steel collection plates, and a continuous plate wash at flue gas velocities of 7ft/s and 10ft/s. Rigid discharge electrodes were used with long and short pins. Performance of the electrodes was evaluated using voltage-current plots and comparative collection efficiency tests. Long pin electrodes produced more current 50mA at 70kV as compared to 32mA for short pin electrodes. The collection efficiency of both electrodes was within 7% for most cases. It was concluded that long pin electrodes would be more effective at capturing fine particles because of the larger current production. Long pin discharge electrodes had slightly higher collection efficiencies at the maximum electric field conditions that did not produce excessive sparking. Long pin discharge electrodes proved to the superior discharge electrode under these testing conditions.
