A Study on Reduction of Odorous Substances with Electrostatic Precipitator

Abstract

The electrostatic precipitator is a device for reducing suspended fine particles, which is widely used from home air cleaner to industrial applications. However, odorous substances cannot be almost reduced with the electrostatic precipitator. Most odorous substances are liquids at room temperature, however these become volatile if vaporized. Generally, gaseous substance is not removed from air with electrostatic precipitator. In this study, we investigated that odorous substances are removed with an electrostatic precipitator, and then, odorous substances are reduced by the ozone generated with corona discharge. The measurement of odorous substances is used odorous sensor corrected for ozone concentration. Furthermore, collected substances at collected electrode in electrostatic precipitator are analyzed by a Fourier transform infrared (FT-IR) with the Nujol methods.
