FIELD: fire-prevention facilities.SUBSTANCE: invention relates to fire-fighting equipment, and more particularly to automated devices of 3D fire fighting of combined action. The fire extinguishing module comprises a container, a gas generator, a solid fuel pyrotechnic stick and an initiation unit. The container is filled with fire extinguishing agent, primarily, fluorinated refrigerant. The container is made in the form of a housing with bottoms one of which has an opening. The housing is provided with low-melting hollow cylindrical insert which has end sealing flanges. The insert is mounted in the housing opening by the upper flange. The gas generator has nozzles and is installed in the housing by inserting the lower insert flange. The upper part of the gas generator comprises nozzles and the initiation unit and is placed in the cavity of the insert. The lower part of the gas generator with a solid fuel pyrotechnic stick is immersed in the fluorinated refrigerant. The gas generator nozzles are made in the lateral surface of the gas generator and focused on the cylindrical surface of the insert.EFFECT: invention provides the ability to obtain a fire extinguishing mixture with low temperature, high optical transparency and minimal content of solid particles.11 cl, 2 dwg |
