Description
Technical field
The present invention relates to the extinguishing chemicals that a kind of storage state is liquid.
Background technique
With the fast development of national economy and the continuous improvement of people's livelihood awareness of safety, fire-fighting fire-extinguishing equipment is extensive
It uses, is also equipped with fire fighting device and extinguishing device in numerous occasions.
The fire extinguisher used in fire-fighting mainly has a fire foam, carbon tetrachloride extinguishing chemical at present, dry powder fire extinguishing agent,
Heptafluoro-propane extinguishing chemical, carbon dioxide extinguishing agent etc., their scope of application is not wide enough, has some limitations.
Traditional combustion theory thinks that combustion process is the interaction process of combustible, oxidizer and temperature three elements.It wants
To knock down the flame, it is necessary to remove one in three elements, i.e. removing combustible, starvation or cooling.Nearest research thinks,
Other than above three fundamental, combustion process is with the four elements-free radical, this i.e. tetrahedron Theory of Combustion or freedom
Base Theory of Combustion.
The theory thinks, combustion process there are free radical lock reactions, since this reaction speed is exceedingly fast, to control
Flame growth rate.In combustion, can there are many free radicals to occur, the main body meeting of different its free radical of fire type
It changes.And the extinguishing mechanism of existing extinguishing chemical is mainly to be completed by eliminating active combustion carrier, that is, is blocked
Chain propagation reaction in flame.
Fire situation, after often putting out a fire because of first time, comburant and oxidizer are still had, and temperature is by the once time
After rising, the phenomenon that resulting in fire re-ignition, it is therefore desirable to a kind of to prevent from rising the extinguishing chemical for leading to the secondary re-ignition of fire because of temperature
And extinguishing device.
Various extinguishing chemicals are also developed accordingly with the development of science and technology, so as to the need of suitable different fire type
It wants.The purpose of the present invention, is to provide that a kind of use scope is wide, and the fire extinguishing type of suitable emerging industry fire characteristics has and goes out
There are physics, inhibition good during fire simultaneously and prevents the extinguishing chemical of secondary re-ignition.
Summary of the invention
It is the extinguishing chemical of liquid the main purpose of the present invention is to provide a kind of storage state,
Technical scheme is as follows:
A kind of storage state is the extinguishing chemical of liquid, and by volume, it includes:
2-10 parts of liquid-state extinguishing agent, 50-85 parts of liquid heptafluoro-propane and 15-45 parts of dry ice are higher than room temperature two in pressure
Carbon oxide gas is converted under the pressure condition of liquid and mixes.
A kind of storage state is the preparation method of the extinguishing chemical of liquid, is included the following steps:
1) liquid-state extinguishing agent first, is added in steel cylinder according to ratio above-mentioned in steel cylinder container size；
2) heptafluoro-propane extinguishing chemical, is added in ratio above-mentioned, is higher than room temperature heptafluoro-propane gas in pressure and is converted into liquid
It is mixed under the pressure condition of body；
3) carbon dioxide extinguishing agent, is finally filled, is higher than the pressure that room temperature carbon dioxide gas is converted into liquid in pressure
Under the conditions of mix.
Heptafluoro-propane (HFC-227ea/FM200) is one kind based on inhibition, has the cleaning of physics fire extinguishing effect concurrently
Gas extinguishing agent；Storage space is small, and critical-temperature is high, and critical pressure is low, and liquefiable stores at normal temperature；Good gas phase electricity is absolutely
Edge, be suitable for total flooding fire-fighting mode fighting electrical fire, liquid fire or fusible solid fire, surface of solids fire,
The gas fire of gas source can be cut off before fire extinguishing, protect computer floor, communication machine room, changed into switchhouse, precision instrument room, generator
Room, oil depot, chemical inflammable thing storehouse and Library, data bank, file store, national treasury etc. places.
Dry ice extinguishing chemical: solid carbon dioxide is commonly called as dry ice, and dry ice is used to make fire-fighting fire extinguishing, and when distillation is absorbable a large amount of
Heat plays the role of huge Physical temperature-lowering fire extinguishing as extinguishing chemical, while carbon dioxide does not burn generally and do not support to burn yet, and is
One of common extinguishing chemical；Dry ice is applied fewer in fire-fighting domain at present.
The present invention combines the physics of above 2 kinds of extinguishing chemicals, inhibition advantage, has taken into account physics and inhibition is former
Reason, meanwhile, using the characteristic of carbon dioxide, is just stored with high pressure in extinguishing chemical storage, become properties of carbon dioxide can
Change, form dry ice, density is bordering on liquid, and viscosity is bordering on gas；The extinguishing chemical of this mixing, has powerful physics, chemistry
Extinguishing ability.Meanwhile because dry ice has powerful Physical temperature-lowering ability, secondary re-ignition caused by rising because of temperature can be prevented existing
As.
Liquid-state extinguishing agent is changed according to practical fire type, in original heptafluoro-propane and carbon-dioxide fire engine
It is optimized on the basis of energy.Liquid-state extinguishing agent of the present invention includes water, foam, 7150 or at least one of 2130D.Institute
7150 extinguishing chemicals stated are extraordinary extinguishing chemicals, and being suitable for its main component of fighting D class fire is metaboric acid trimethyl.Foam goes out
Fiery agent usually has protein foam, fluoroprotein foam, " light-water " foam, water-resistant foam, middle and high ploidy foam etc..Water, foam or
7150, when 2130D is mixed, it is preferably in a proportion of 1-10:1-10:1-10:1-10.The present invention is provided simultaneously with heptafluoro-propane and titanium dioxide
The advantages of carbon or dry ice, the change of liquid-state extinguishing agent properly a variety of fire types or extraordinary fire.
Advantages of the present invention is as follows:
1, it is stored using high pressure, pressure is higher than the pressure that room temperature carbon dioxide gas is converted into liquid, makes two kinds of extinguishing chemicals
It is simultaneously liquid condition.The state for having excellent Physical temperature-lowering fire extinguishing.When the mixing extinguishing chemical of high-pressure liquid is discharged to fire
It when occasion, is converted from liquid to gaseous process, absorbs a large amount of heat in conversion process, be conducive to drop the temperature of conflagration area
To flammability temperature point.The fire extinguishing advantage of comprehensive 2 kinds of extinguishing chemicals, suitable for a variety of fields for needing sharply to cool down with inhibition
It closes.
2, heptafluoro-propane content 50% to 85%；Storage state is liquid；Dry ice content 45% to 15%；Because of heptafluoro-propane
When also storing also based on liquid, in fire situation, liquid gasification also has certain Physical temperature-lowering effect.Therefore, dioxy
The ratio for changing carbon is fewer than heptafluoro-propane.
3, the characteristic needed according to fire situation, physics, inhibition, carries out the adjustment of extinguishing chemical ratio.Fire temperature
The ratio of the occasion that relatively high or temperature easily rises, dry ice improves.At present with heptafluoro-propane put out a fire based on occasion, dry ice
Ratio can be reduced suitably.
