휘발성 유기화합물 제거를 위한 무성방전 공정의 전기 및 화학적 특성에 미치는 운전변수의 영향
2005
The effect of operating parameters on electrical characteristics and benzene removal properties
in the dielectric barrier discharge(DBD) process was investigated. The benzene removal was
initiated with the energy transfer to the gas stream by the loading of voltages higher than the
discharge onset value. The removal efficiency over 95% was obtained at the 27kV peak value of
applied AC voltage. The discharge onset voltage of the coarse surface electrodes was lower than
that of the smooth surface electrodes. As gap distance between electrodes decreased, the
discharge onset voltage was decreased and the energy transfer to the gas stream was increased
due to the higher electric field strength. The decrease of the dielectric material thickness
enhanced the removal efficiency by increasing the discharge potential. The benzene removal was
closely related to the amount of transferred energy. The higher electrical energy transferred to
the gas stream, the higher benzene removal efficiency was obtained.
