Combination effects of acoustic field and humidity on removal of inhalable particles
The removal efficiency of inhalable particles was investigated in standing-wave field, with a sound pressure level varying from 100 to 130 dB and a frequency varying from 200 to 3500 Hz. A diluted gas flow through a humidifier was employed to adjust the humidity of the agglomeration chamber. Experimental findings indicated the combination of sound field combined with proper gas humidity could reduce about 28.6％ of inhalable particles. This Value was obtained in a sound field with the frequency of 1416 Hz and sound pressure level of 127.5 dB at 40％ relative humidity in acoustic agglomeration chamber.
