Analysis of Plasma Ion Distribution and Dust Collection Efficiency of Carbon-Brush Air Purifiers

In recent years, many studies on air purifiers have been conducted, as particulate matter and virus issues emerged. this study, the ion concentration distribution in an purifier that applies a high voltage was investigated through simulation. For single carbon brush applied of –8.5 kV, simulation results ground direction were compared with result experiment error 4.3% observed, thereby confirming reliability On basis, calculated according to number location brushes. addition, charging by applying mechanism distributed dust particles, collection efficiency conducting particle multiphysics analysis. The increased from 0.5% 1% brushes increased, 82% when there two 83% four proposed modeling, is more important than These are expected provide accurate design information for applicable purifier.
