Nowadays the fine particle emission from the vehicles, power plants, and industries has been revealed to cause the critical respiratory diseases like silicosis and asbestosis, thereby the atmospheric particulate matter (PM) concentration is being considered as a proxy indicator of air pollution. Therefore, many researchers are paving the way to increase collection efficiency of various industrial dust precipitators. As one of their efforts, the wet electrostatic precipitator (Wet-ESP) has been drawing attentions due to its higher collection efficiency and self-electrode-cleaning nature. However, its commercialization is still far from the real market because it requires large amount of water and electricity consumption and high investment cost for installing. In this study, we propose the electrostatic spray inserted cyclonic wet ESP, which can minimize the disadvantages of aforementioned wet-ESP.
Electrostatic spray in general refers to the technique to produce ionized liquid droplets from electrically conductive water solution. The highly charged and fine water droplets can draw the fine particles by electrostatic attraction. By visualization experiments, we suggest that the optimized spray motion for collecting fine dusts were acquired for 0.5 mm in inner diameter of nozzle, 80 mm in nozzle to electrode distance, 10 sccm in water flowrate through a nozzle, and 40 kV in the applied voltage. With those multi-nozzle design and swirling motion of air inside a cyclone motion, we achieved very high collection efficiency for PM10, PM2.5 and even PM1.0, which are 98.2%, 95.4%, and 90.3% for 7.5 CMM in air treatment capacity, 1.0 LPM in water supply (about 13.8 sccm per a nozzle), and 45 kV in applied voltage.
