Microwave Plasma를 이용한 악취[TMA, Acetaldehyde] 처리 특성 연구
Abstract
The purpose of this research was to study treatment characteristics of main odor substances, such as Trimethylamine and Acetaldehyde, by using 600 Wand 200 W microwave plasmas. Ar and air were used as plasma gases and a cylindrical SiC/Zeolite filter having several Ø 2~3 ㎜ size holes was used as a trigger to obtain a stable plasma even with a relatively low microwave power. The 600 W Ar plasma was used to destroy relatively high concentrated TMA and acetaldehyde from 500 ppm to 2200 ppm and their DREs (Destroy and Removal Ratios) were measured. The 200 W air plasma was also used to measure DREs for TMA and acetaldehyde Jowly concentrated in 4.5 odor strength. The results demonstrated that the Ar plasma produced 70% to 90% efficiency in removing odors substances. The 200 W Air plasma, which was operated at the relatively lower energy level, produced 90% or even above higher efficiency for the odorous materials. It was expected that the air plasma was effectively used to control odorous materials emitted from relatively a small size plant process.
