How critical is geometrical confinement? Analysis of spatially and temporally resolved particulate matter removal with an electrostatic precipitator.

ABSTRACT: This study investigates the spatial and temporal dispersion of particulate matter (PM) when using a needle-type electrostatic precipitator (ESP). The ESP is installed in tubes of 3 and 10 cm diameter. A simple light scattering setup integrated with image processing is built to evaluate and quantify the spatial and temporal dispersion of PM. The ESP is operated under stationary and continuous flowing modes to test its PM removal capability. Under the stationary mode, PM is removed efficiently in 10 and 45 seconds when using a 3 and 10 cm tube, respectively. In a more geometrically confined system, a large spatial particulate concentration gradient is seen from 18 to 24 cm, indicating that the cleaning capability can be controlled within a localized space.
