A kind of standby cabinet type perfluorethyl isopropyl ketone extinguishing device of pressure
Technical field
The utility model belongs to fire-fighting equipment field, and in particular to a kind of standby pressure cabinet extinguishing equipment.
Background technology
It is cabinet type fire extinguishing system small volume, easy for installation, computer room, laboratory, archives, storage of valuables, car can be arranged on
In the less guard plot in the spaces such as storehouse.For above-mentioned place, once occur fire or disaster hidden-trouble occur, it is necessary to flutter at once
Go out, otherwise, difficult to the appraisal, irremediable loss can be caused.Heptafluoro-propane extinguishing chemical available for cabinet type fire extinguishing has in itself
Some toxicity, when concentration reaches more than 10%, uncomfortable sensation just occurs, time length can also be in peril of one's life.It is another
Aspect, the analyte produced by heptafluoro-propane is decomposed at high temperature mainly includes the fluorine in extinguishing chemical, is deposited there is protium
Environment in can produce the hydrogen fluoride (HF) with acrid odors.Even if its concentration very little, it can also give people to cause largely
Do not accommodate injury.Therefore, Fire-extinguishing System of Septenary-Fluorine Propane can only be put out a fire on the premise of nobody, once occur fire, no
It can be put out a fire the very first time, delay optimal fire extinguishing opportunity.
Perfluorethyl isopropyl ketone is a kind of clean fire extinguishing agent, and most prominent advantage is environmental protection, safe to the human body,
Simultaneously but also with excellent extinguishing property.The material is liquid at normal temperatures, without solid particle, without grease, after release not
Residue is left, is suitable for clean place and uses.Perfluorethyl isopropyl ketone has that fire-fighting efficiency is high, corrosion-free, toxicity is low, exhausted
Edge is strong, and stores many merits such as air pressure is low, transport performance is good, and overcomes the temperature that hydrogen fluorohydrocarbon class extinguishing chemical has
Room effect problem;It is liquid under normal temperature, without hig pressure storage, security is good, convenient transportation;Fire extinguishing is wide, and extinguishing ability is strong, its
Extinguishing concentration is 4-6%, and extinguishing ability can compare favourably with imperial 1301 (extinguishing concentration is 5%) are breathed out.Put out a fire as dragon series is breathed out
The ideal substitute of agent.At present, in the field of cabinet type fire extinguishing system, the use of perfluorethyl isopropyl ketone still belongs to blank shape
State.
