Abstract

The invention provides a fire extinguishing system based on sound wave fire extinguishing and a fire extinguishing method thereof. The fire extinguishing system based on sound wave fire extinguishing comprises a waveform generator used for generating low-frequency sound wave analog electric signals, a power amplifier used for amplifying the low-frequency sound wave analog electric signals, an electro-acoustic transducer used for converting the amplified low-frequency sound wave analog electric signals into low-frequency longitudinal waves and directionally transmitting the low-frequency longitudinal waves in the transverse direction, and a partition body used for reflecting the low-frequency longitudinal waves to form a superposed sound field and carrying out reflection enhancement on the transmitted longitudinal waves in the advancing direction of the low-frequency longitudinal waves. A stable superposed sound field is formed in the interval space between the electro-acoustic transducer and the partition body, and a high pressure gradient generated in the superposed sound field can cause a transverse density difference at the moving position of the moving flame, so that the flame of the moving flame transversely deviates from a fuel area, the flame is quickly extinguished in the superposed sound field, and spreading and secondary ignition of moving flames are prevented.

Description

Technical field[0001]The present invention belongs to the field of fire extinguishing firefighting, and more particularly, it is to involve a fire system based on an acoustic fire extinguishing and a fire extinguishing method thereof.Background technique[0002]The moving flame is formed by changing the fire source position under a combination of external force (e.g., environmental wind, gravity, etc.) affecting the factors of external force (such as environmental wind, gravity, etc.). Mobile flame is a common phenomenon in the fire, such as the woodfire particles produced in the forest fire, the drop flames produced by the plastic insulation layer in the building fire. Flying particles affected by the wind and the fallen flames that are gravity active, and the flames carrying the flames can easily ignite other combustible materials around them, causing secondary combustion. However, since the mobile flame in the fire is generally small, the movement speed is faster, and the movement ...
