Abstract

The invention discloses a fire extinguishing system based on a perfluoro(2-methyl-3-pentanone) fire fighting agent, and relates to the technical field of fire fighting manufacture. The fire extinguishing system comprises a perfluoro(2-methyl-3-pentanone) storage tank, a dry powder extinguishing agent storage tank, a fine water mist water storage tank, a mixer and a spray head, wherein an outlet isconnected with a first inlet of the mixer through a first pipeline by a first regulating valve, one end of a second pipeline communicates with a first pipeline through a three-way pipe, and the otherend of the second pipeline is connected with a first outer ring inlet of the spray head through a second adjusting valve; an outlet are connected with a second inlet of the mixer through a third pipeline by a third adjusting valve; an outlet is connected with a second outer ring inlet of the spray head through a fourth pipeline through a fourth regulating valve; an outlet is connected with a middle inlet of the spray head through a fifth pipeline; the spray head is used for spraying a powdery fire extinguishing agent in the middle and / or spraying a perfluoro(2-methyl-3-pentanone) fine water mist fire extinguishing agent on the outer ring. The system has the advantage of high safety.

Description

technical field [0001] The invention relates to the technical field of fire-fighting manufacturing, in particular to a fire-fighting system based on perfluorohexanone fire-fighting agent. Background technique [0002] Because of the destruction of the atmospheric ozone layer, the use of halon fire extinguishing agents is banned worldwide, and clean chemical gas fire extinguishing agents such as heptafluoropropane, trifluoromethane, perfluorohexanone, and bromofluoropropene are used as alternatives due to their high efficiency, cleanliness, and environmental protection. and many other advantages. [0003] However, studies have shown that, as a class of fluorine-containing hydrocarbons, the amount of toxic and corrosive gas HF produced by this type of clean chemical gas fire extinguishing agent in the fire extinguishing process is 5-5 that of Halon 1301 under the same fire source. 10 times. HF is a poisonous strong acid gas, which can seriously corrode metal equipment and el...
