Description
Technical field
The invention belongs to the technical fields of extinguishing chemical, and in particular to a kind of to have utilized heptafluoro-propane, carbon dioxide and perfluor
The mixing extinguishing chemical of ketone.
Background technique
Since existing new-energy automobile is all using lithium ion battery as dynamical system, and lithium ion battery is transported in vehicle
During row, there are some potential safety problemss, especially in abuse conditions, such as vehicle overcharges during the charging process, over-discharge,
Squeeze, needle thorn, burn etc. when, lithium ion battery be easy to happen smolder, it is on fire in addition explosion safety accident.Therefore,
On-vehicle battery can all be equipped with fire extinguisher.Fire extinguisher is by storage unit, action component, extinguishing chemical composition.
Existing extinguishing chemical, which has, uses carbon dioxide as fire extinguishing material, also has using heptafluoro-propane as fire extinguishing material
, but in the market there is not yet using the mixing extinguishing chemical mixing of heptafluoro-propane+carbon dioxide+perfluor ketone as going out simultaneously
The fire extinguisher of fiery material.It is very sensitive to temperature as the fire extinguisher of fire extinguishing material using pure carbon dioxide, it cannot be heated, still
Carbon-dioxide fire engine sprays speed height, good cooling effect, while carbon dioxide can play good object because its storage pressure is higher
Manage cooling effect, but without chemical cooling function, using pure heptafluoro-propane as material of putting out a fire fire extinguisher then with pure titanium dioxide
Carbon fire extinguisher is on the contrary, up to 700 ° of the decomposition indexing of heptafluoro-propane, and heat-resist, spray speed is low, of less demanding to nozzle, but valence
Lattice are relatively high, and lowering ability is lacking, and are substantially carried out chemical cooling.Perfluor ketone as a kind of fire-extinguishing agent,
Its dominant mechanism of putting out a fire is fire smothering, but the slightly deficiency in several chemical cooling features of Physical temperature-lowering.
Summary of the invention
The shortcomings that in order to overcome above-mentioned existing extinguishing chemical to be used alone, the purpose of the present invention is to provide one kind to combine seven
The advantages of fluoro-propane, carbon dioxide and perfluor ketone extinguishing chemical fire extinguishing, carries out physics, chemistry cooling and fire smothering simultaneously, reaches
To better fire extinguishing cooling effect.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows:
A kind of mixing extinguishing chemical using heptafluoro-propane, carbon dioxide and perfluor ketone, in which: mixing extinguishing chemical is by seven fluorine third
Ketone forms for alkane, carbon dioxide and perfluor, wherein heptafluoro-propane accounts for 3% to 50% (by weight) of intermixture, and carbon dioxide accounts for
10% to 80% (by weight) of intermixture, ketone accounts for 10% to 80% (by weight) of intermixture to perfluor.
To optimize above-mentioned technical proposal, the concrete measure taken further include:
Heptafluoro-propane, carbon dioxide and perfluor ketone be pre-mixed it is rear canned to storing in extinguishing device.
Three kinds of ingredients of ketone are completely separable for heptafluoro-propane, carbon dioxide and perfluor, independent container filling storage, sprinkling fire extinguishing
Mixing sprinkling is carried out again using preceding.
Heptafluoro-propane and carbon dioxide are pre-mixed rear canned to storing in extinguishing device, perfluor ketone independence container filling
Storage, by perfluor, ketone carries out mixing sprinkling with the intermixture of heptafluoro-propane and carbon dioxide again before for sprinkling fire extinguishing；Or seven
Ketone is pre-mixed rear canned to storing in extinguishing device, carbon dioxide independence container filling storage, sprinkling for fluoro-propane and perfluor
By carbon dioxide and heptafluoro-propane and perfluor, the intermixture of ketone carries out mixing sprinkling using preceding again for fire extinguishing；Or perfluor ketone and two
Carbonoxide is pre-mixed rear canned to storing in extinguishing device, heptafluoro-propane independence container filling storage, before sprinkling fire extinguishing use
By heptafluoro-propane, the intermixture of ketone and carbon dioxide carries out mixing sprinkling with perfluor again.
Ketone at least one is not pre-mixed for heptafluoro-propane, carbon dioxide and perfluor, and extinguishing chemical ingredient passes through respective spray
It spills device and is separately sprayed onto the same area, mixing fire extinguishing is carried out outside extinguishing device.
Ketone as fire extinguishing material, heptafluoro-propane is extinguishing chemical of the invention using heptafluoro-propane and carbon dioxide and perfluor
One kind having the clean coal power system of physics fire extinguishing effect concurrently based on inhibition；Storage space is small, and critical-temperature is high, faces
Boundary's pressure is low, and carbon dioxide is physically to put out a fire, and when carbon dioxide is changed into gaseous state from liquid, can absorb big calorimetric, rises
It being acted on to huge Physical temperature-lowering fire extinguishing, ketone is as Novel clean extinguishing chemical for perfluor, by remarkable result in fire smothering, and
Have both certain cooling effect.The present invention combines the object of the above heptafluoro-propane and carbon dioxide and perfluor three kinds of extinguishing chemicals of ketone
Reason, inhibition advantage, have taken into account physics and inhibition principle.This combined dose the advantages of combining three kinds of extinguishing chemicals,
On-vehicle battery is particularly suitable for put out a fire this occasion for needing sharply to cool down with inhibition, but not limited to this occasion, especially
It is needing to reduce under the quadratic loss occasion of protection target, had better effect with such extinguishing chemical.
