FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment and can be used for deposition of smoke when extinguishing fires in conditions of strong smoke. Technical result is achieved due to exposure of smoke to acoustic vibrations at ultrasonic frequencies in the range of more than 22 kHz for accelerated coagulation of fine particles, creation of ultrasonic oscillations simultaneously by two emitters, natural frequencies of which differ insignificantly by the specified value, changes in natural frequency of emitters within certain limits for creation, during interaction of ultrasonic vibrations, sound vibrations (beats) with a frequency range of 150…400 Hz at a given distance from the radiators (in a certain size-limited volume where there are no people) for deposition of pre-formed large smoke particles.
EFFECT: higher efficiency of smoke deposition.
