Abstract Scope |
The fine particles in the media such as air and water have been recently caused environmental pollution. Especially, the fine dust in the polluted air has been challenged to solve with conventional techniques such as physical filtering, electrostatic precipitator, green wall, etc.
We investigated the innovative technology for agglomerating the dispersed fine particles in air induced by acoustic waves with the frequency ranging from 20Hz to 20kHz, which is designed to possibly reflect in-phase waves within the various rigid housings.
When the low frequency under 50Hz was applied in the rigid housings with ultra-fine particles, the rate of agglomeration of ultra-fine particles was nearly 5 times higher than that without operating.
It is concluded that the agglomeration behavior of ultra-fine particles was effectively induced by an acoustic wave, and also is expected to be applied to the inter-structure and intra-structure having the polluted air. |
