The invention relates to fire fighting equipment, in particular, to devices providing automatic delivery of a fire extinguishing composition to the combustion zone.

The aim of the invention is to increase the efficiency of fire suppression.

Figure 1 presents the proposed device, a longitudinal section; Fig. 2 is a diagram of the connection of the device into one system, bottom view.

The device contains a container that is a section 1 of a fire extinguishing medium with base 2, a closed membrane 3 of a flammable active burning film, on which a fire extinguishing composition 4 is held in the case 4. In the middle part of the membrane 3, there is a pyro-igniter 5 connected to the command system with wires 6. The sections are interconnected by strips 7 of a highly flammable, actively burning film.

The device works as follows

When a command electric pulse arrives, the pyro-igniter 5 is triggered and the membrane 3 is ignited, which, at the speed of smoked gun powder, releases the fire extinguishing composition 4. Under its own weight, the fire extinguishing composition 4 is poured down and falls asleep. Thanks to great speed

burning membrane 3 fire extinguishing composition 4 is distributed over the area of the object evenly,

If the initiation system fails, the device works as follows.

The flame of the fire, reaching the membrane 3, ignites it. Combustion, membrane 3 releases the extinguishing agent and, through lanes 7, initiates the membranes of adjacent sections of the carrier installed in the protected room, causing them to fire, which prevents the spread of fire throughout the room.

Claims (1)

Invention Formula A fire suppression and explosion suppressor device comprising a carrier of a fire extinguishing composition held by a flammable material located in of the carrier’s bottom part, in order to improve the suppression of fire and explosion by providing coverage of any size of the protected area, the carrier consists of sections interconnected by strips of flammable material, while the extinguishing agent is located in each section the carrier and the flammable material are made in the form of a set of membranes, each of which overlaps the corresponding section and is equipped with a pyro-igniter.
