DEVICE FOR COMBINED FIRE EXTINGUISHING AND FIRE-AND-EXPLOSION PREVENTION OF FOAM OF LOW AND MEDIUM MULTIPLICITY Russian patent published in 2019 - IPC A62B15/00 

FIELD: fire safety.

SUBSTANCE: invention relates to fire extinguishing equipment and fire-and-explosion prevention, namely, to devices for combined extinguishing of large-scale fires of classes A and B and for fire-and-explosion prevention air-mechanical combined foam of low and medium ratio. To increase fire extinguishing efficiency and explosion and fire prevention due to increased range and uniform distribution of foam medium and low multiplicity by area of fire and increased safety of fire extinguishing process and fire-and-explosion prevention on especially fire and explosion hazardous facilities, device for combined fire extinguishing and fire-and-explosion prevention foam of low and medium ratio comprises two fixed on the crossarm generator combination foam of low and medium multiplicity, comprising housing with installed inside housing packet of foam generation medium multiplicity, located in front of housing unit of nozzles supplying aqueous solution foaming agent on packet of meshes of generation of foam average ratio, low-expansion foam formation barrel, a foaming agent water solution supply duct to the nozzles and the low-ratio foam formation barrel and the foam generator connection device to the foaming agent aqueous solution pressure line, facility for automated turns of crossarm with foam generators fixed on it in vertical and horizontal planes.

EFFECT: higher efficiency of fire extinguishing and fire and explosion prevention.
