High speed deodorization technology using plasma induced flow

Le résumé fourni par la source

In recent years, there has been an increasing need to improve air quality in living spaces such as homes, offices, hospitals, etc. In this study, we developed a high-speed deodorizer using a plasma actuator (PA) and evaluated its deodorizing performance against tobacco odor, toluene gas, and ethylene gas. The PA generates plasma-induced flow through dielectric barrier discharge, which draws odorous molecules into the plasma and decomposes them with OH radicals. In this study, we conducted deodorization tests in accordance with JEM1467 and compared the performance with commercially available filter-type deodorizers. The deodorization performance tests confirmed that the PA deodorizer meets the JEMA (Japan Electrical Manufacutures Association) standards for all five tested odorous molecules (ammonia, acetic acid, acetaldehyde, toluene, and ethylene). Notably, it demonstrated excellent decomposition and deodorizing performance for ethylene gas, which is difficult to deodorize through adsorption.
