Abstract

The invention provides a novel ultrasonic standing wave fire extinguishing system. The system mainly comprises an ultrasonic wave emission end, an ultrasonic wave reflection end, a power amplifier anda control power supply. According to the system, ultrasonic waves are generated through vibration of piezoelectric ceramics at the emission end due to high-frequency signals generated by the controlpower supply, and the reflected ultrasonic waves and incident ultrasonic waves are superposed for forming standing waves. The ultrasonic frequency is controlled to be near the inherent frequency of the system, so that acoustic radiation pressure of the maximum power is achieved. Air in the ultrasonic standing wave range is limited within a small range, and can not flow randomly; meanwhile, ultrasonic standing wave environment further has a certain cooling function, so that flame in the ultrasonic standing wave range can be extinguished quickly; compared with other fire extinguishing schemes, the standing wave fire extinguishing system has the advantages that spraying of water or other fire extinguishing materials is not required, and meanwhile the system can be enabled continuously. The whole system is simple in structure, and especially suitable for specific fire protection of some fixed high-risk circuit interfaces or sophisticated instruments and equipment.

Description

technical field [0001] The invention belongs to the field of ultrasonic technology, in particular to an ultrasonic standing wave fire extinguishing system. Background technique [0002] Existing fire extinguishing methods are mainly through the use of water, CO 2 , Foam and other flame retardants cut off the air supply of the fire source so as to achieve the purpose of fire extinguishing. These fire extinguishing methods have a common problem that their residues may cause secondary damage to the fire facilities, especially for some high-precision equipment. And these fire extinguishing means can only carry out after-the-fact remedy after the fire takes place, can't contain the flame in advance before the fire takes place. Therefore, how to provide a non-contact fire extinguishing solution that can contain fire in advance is a technical problem to be solved urgently by practitioners in the field. [0003] Ultrasound, as a hot spot in acoustics, has many characteristics suc...
