摘要

FIELD: fire-fighting equipment; localization of explosion of air-dust or air-gas explosive mixtures, formed in service lines communicating production equipment at the enterprises of grain storage and processing. SUBSTANCE: the offered method includes establishment of seal which is provided by introduction of inhibiting aerosol at supersonic velocity to explosive zones of service lines. The offered method is realized with the help of device having double-efflux generator of inhibiting aerosol. Generator body is provided on the side of outlet screens with nozzle units having internal geometry ensuring supersonic efflux of aerosol at angle of 15-30 deg to service line axis, for instance, in form of Laval nozzle. Nozzle units have joining flanges to connect with axially parallel service lines. Generator body on the side of outlet screens is extended through a value sufficient for connection of nozzle unit. EFFECT: higher efficiency in localization of explosion of air-dust or air-gas explosive mixtures in production equipment. 2 cl, 2 dwg
