세탁기에서 열전소자를 이용한 VOCs 회수에 관한 연구
백선호(Seon-Ho Baek)⋅이운기(Un-gi Lee)⋅;오명도(Myung-Do Oh) 한국실내환경학회 2008 한국실내환경학회지 Vol.5 No.4
Recently, it was under an obligation to install the VOCs recycling unit in the cleaners and the gas station to prevent from discharging VOCs emitted from the cleaners and the gas station. The objectives of this study was to investigate the VOCs recycling unit used thermoelectric module to recycle the organic solvent from the cleaners and after washing. The traditional way was the use of the VOCs recycling unit with the compressor. But the recycling unit has many weak points ; noise, size, danger of fire, additional pollution and so on. In order to improve these weak points, it was developed the new VOCs recycling unit using the thermoelectric module through this study. The cooling block with 32 thermoelectric module was applied to cool the hot VOCs where comes to occur from the dryer in high temperature condition. Also a water-cooled equipment was used to remove the heat from the hot surface of thermoelectric module. The experimental results from new VOCs recycling unit shows that the maximum recovery rate of the unit was 83.2 % and the recycled VOCs' purity was 98 % or more. And the noise problem was solved by applying the thermoelectric module to the VOCs recycling unit.
