A Study on Ignition Suppression Effect of Sound Component in Sound Fire Extinguisher
Since modern society is highly dependent on the information network, the conflagration of information network dense facilities causes huge economic losses. There is a risk of ignition due to accumulation of polymerizing heat due to electrical characteristics in information network densification facilities. Therefore, in addition to the existing extinguishment method in which the fire extinguishing agent is sprayed when conflagration occurs, preventive measures for separate ignition suppression are required. In this study, we tried to confirm that sound fire extinguisher is effective to suppress ignition by supplying sound component before conflagration. Match ignition experimental results applying the heating crucible measurement, ignition was performed at an average temperature of 109degC when no sound was supplied, and ignition was performed at an average of 129degC when the sound was supplied. Also, if the sound was not supplied, the match took about 38 seconds from 60degC to the ignition, while it took 173 seconds from 60degC to the ignition when the sound was supplied. Even if the sound was supplied very close, the match and ambient temperature did not rise to the ignition point. These results show that the sound component of Sound Fire Extinguisher suppresses ignition and prevents conflagration.
