Background

With the elimination of halon fire extinguishing agents, a variety of alternatives to halon fire extinguishing agents have emerged in recent years, such as heptafluoropropane, hexafluoropropane, trifluoromethane, and the like. The existing mature heptafluoropropane fire extinguishing system on the market is considered to be one of the most ideal products for replacing the alkyl halides 1301 and 1211, but the global warming potential GWP is higher, the fire extinguishing design concentration reaches 8% -10%, and the U.S. Environmental Protection Agency (EPA) sets the safe use concentration of HFC-227ea to be 9%, and the concentration of HFC-227ea can only be used for 1 minute when the concentration is 10.5%.

The next cleaner and more environmentally friendly ODS substitute, perfluorohexanone, a fire extinguishing agent known by the foreign name Novec1230, was successfully developed, and this revolutionary technology uses a new chemical agent, which has several advantages over heptafluoropropane: the fire extinguishing concentration is lower, the potential value of greenhouse effect is lower, the survival time in the atmosphere is shorter, the fire extinguishing agent is in a liquid state at normal temperature, the fire extinguishing agent is easy to transport and store, and the harm to human bodies is less.

In some embodiments, the fire extinguishing container 10 is cylindrical, and in other embodiments, the fire extinguishing container 10 may have other shapes, such as a conical shape, a rectangular parallelepiped shape, and the like, without limitation.

In some embodiments, the injection assembly 20 further comprises an injection pipe 22, and the injection pipe 22 is used for communicating the nozzle 21 with the accommodating chamber 11. Further, the heating module 40 is disposed inside the injection tube 22, that is, the injection tube 22 has a communication path between the housing chamber 11 and the nozzle opening 21.

In some embodiments, the driving device 30 includes a high-pressure gas filled in the accommodating chamber 11, and the driving device 30 further includes an actuating member disposed at the nozzle opening 21, the actuating member including an open state that the accommodating chamber 11 communicates with the outside of the fire extinguishing container 10 through the nozzle opening 21, and when the actuating member is in the open state, the high-pressure gas is used for driving the liquid perfluorohexanone 12 to be sprayed from the accommodating chamber 11 to the nozzle opening 21 along the spraying path. Specifically, the actuator includes a communication valve and the high-pressure gas includes nitrogen.

Specifically, the gas generant may be located in the space between the inner wall of the receiving chamber 11 and the surface of the liquid perfluorohexanone 12, and in some embodiments, the gas generant may be an aerosol gas generant.

By using the gas generating agent and the driving pump, the non-pressure state in the accommodating cavity 11 and the driving device 20 can be kept before the fire extinguishing device 100 extinguishes fire, so that the fire extinguishing device 100 can be prevented from being complicated in manufacturing process due to the fact that high-pressure driving gas is stored, and the safety of the fire extinguishing device 100 is guaranteed.
