FIELD: fire-fighting, particularly delivery of fire-extinguishing material.
SUBSTANCE: spraying device comprises at least one spraying nozzle installed in pipeline and connected with disc-like deflector. The spraying nozzle has body with truncated front part connected to main body part provided with carbon dioxide supply channel. Spraying orifices are created in the front body part. One orifice, namely central one, is formed along axial line, other orifices, namely angular ones, are formed in conical surface so that axes thereof are inclined towards axial line. Angle between axes of both orifices is 30-55°. Deflector diameter is not less than 2.5 diameter of circle defined by points of angular orifices crossing with conical surface.
EFFECT: increased carbon dioxide delivery distance and increased speed of temperature reduction in fire site.
