EXPERIMENTAL STUDY ON THE CONTAMINANT REMOVAL EFFICIENCY OF AN AIR CLEANER USING THE ADSORPTION/DESORPTION EFFECT

The objective of this paper is to present the contaminant removal efficiency of a prototype air cleanerusing the adsorption/desorption effect and to investigate the practicality of this air cleaner. Toluene andformaldehyde were used as pollutant sources and were emitted at a constant rate in a test chamber.Effects of the number of sorption units, the operational time and mode on the contaminant removalperformance were examined. Sorption materials that were evaluated were a porous material, zeolite,pumice stone, and hydro-corn. As a result of the experiments, zeolite showed a relatively highcontaminant removal efficiency of toluene, and zeolite and the porous material showed a high removalefficiency of formaldehyde for both one-cycle and two-cycle adsorption/desorption modes. Alsosignificant removal performance was observed as the numerical analysis for the continuous operationmode.
