Flame extinguishing device and system.

Abstract

A flame extinguishing device (100) comprising a high-pressure carbon dioxide efferent reservoir (101), a nozzle (102) connected to the efferent reservoir, and a shutter (104) disposed between the efferent reservoir and the nozzle so as to allow the passage of carbon dioxide from the efferent reservoir to the nozzle when the shutter is in the open position and to maintain the carbon dioxide in the efferent reservoir when the shutter is in the closed position. The flame extinguishing device advantageously includes an automatic opening mechanism (105) for the initially closed shutter when the ambient temperature exceeds a first temperature threshold.

Claims

second temperature threshold.

7. System for extinguishing flames on an area, characterized in that it comprises a plurality of flame extinguishing devices (10, 20, 30) according to one of claims 1 to 6, distributed over said area.

8. Flame extinguishing system according to claim 7, characterized in that an efferent reservoir (11, 21, 31, 41, 51) of each of all or part of the plurality of devices, is connected to an afferent reservoir (28, 38, 58) common to at least two devices.

9. Flame extinguishing system according to one of claims 7 or 8, characterized in that it comprises a source of carbon dioxide (190) and at least two accumulator tanks (192, 194) of carbon dioxide connected to each other directly or indirectly, one (194) of the accumulator tanks being connected to the source of carbon dioxide and the other (192) of the carbon dioxide accumulator tanks being connected to at least one related tank (58) of carbon dioxide.

10. Flame extinguishing system according to claim 9, characterized in that at least one carbon dioxide accumulator tank (192) is buried. in
