AEROSOL GENERATOR Russian patent published in 2009 - IPC A62C13/22 B01J7/00 C01B13/02 

FIELD: mechanics; fire-fighting equipment.

SUBSTANCE: invention relates to hardware with the principle of operation consisting in using suspended highly-dispersed solid particles, aerosols, as flame retardants, the aerosol being formed in burning of pyrotechnical grains and released in a protected chamber. Aerosol generator comprises the primer of grains distributed in a cylindrical heat-protected housing combined with the receiver communicating, via a pipeline, with the reverse circular channel formed by a heat exchanger, a casing and a tapered cover. The said casing and tapered cover are arranged reversed and partially overlapping to form an annular outlet nozzle, both being furnished with a heat-protection material interlayer. Note that the said cover rests upon the housing mounted on the central ledge of the casing. The said housing and casing are jointed together with the help of an axial rigging screw, the casing being arranged on a mounting plate with a heat-protection coating acting as a deflector. Note also that the pyrotechnical grains and receiver pipelines are fixed in the housing with the help of gypsum plaster.

EFFECT: simpler design, ease of manufacture, higher efficiency.
