Description
Technical field
The invention belongs to large-scale stored energy power battery pile put out a fire field, and in particular to it is a kind of large size stored energy power battery pile go out
Fiery system and its extinguishing method.
Background technique
The reason of power battery generation fire explosion mainly includes overcharging, being short-circuit, is heated etc..In recent years, large-scale energy storage is dynamic
Power battery pile fire takes place frequently.Such as in July, 2018, chain explosion and fire disaster occur for South Korea's Lingyan Crag Wind energy storage device battery,
Fire occurs in September, 2018, Jiangsu energy storage project, loses huge.Therefore, it needs to study large-scale stored energy power battery pile now
Fire control and extinguishing method and device ensure the person and property safety.
US and European is to carry out power battery fire protection technologies research country earlier.Wherein, National Fire Protection is studied
Foundation (FPRF) has studied water to the effect of fighting lithium battery fire, it is found that water has powerful lowering ability.2009, beauty
Federation of state aviation pipe (FAA) proposes portable lithium battery equipment fire-fighting security warning on aircraft, main packet by studying for many years
It includes two big principles: first is that Kazakhstan dragon, Halon Replacement or water base fire extinguishing device, which can be used, puts out portable lithium battery equipment fire, hindering
Only it spreads；Second is that portable lithium battery equipment is immersed into water or other solvents, secondary mistake is prevented after fire extinguishing
Control.FAA also indicates that the essence of lithium battery fire is the thermal runaway of internal active reaction substance simultaneously, and extinguishing chemical must have foot
Enough abilities that cools just can effectively prevent the groups of fire spread of lithium battery, prevent secondary out of control.In addition, Chinese ship's classification
Society's Wuhan Code and standard also carried out the research of fighting power lithium battery Pool fire extinguishing chemical validity peculiar to vessel, comparative analysis gas
Body carbon dioxide and heptafluoro-propane extinguishing chemical, solid dry powder fire extinguishing agent are to the effect for inhibiting lithium battery.Experimental result discovery, uses
Carbon-dioxide fire engine effect is poor, re-ignition occurs；Dry powder fire extinguishing agent almost without effect, or even is testing lithium battery fire
Explosion is had also appeared in the process；Heptafluoro-propane extinguishing chemical with chemical flame retardant effect is best to fighting lithium battery fire effect,
Re-ignition does not occur.
The fire-fighting principle of traditional above-water method technology is mainly two kinds, first is that Physical temperature-lowering, second is that liquid water flashes to water
The fire extinguishing of steam starvation.Water does not have chemical flame retardant function.Energy-storage battery heap and its attachment belong to electrical equipment, a large amount of water
Spray is accumulated in battery would potentially result in the adverse consequences such as equipment short circuit in corrosion equipment.And root is it was found that energy-storage battery heap goes out
Fire needs to cool down for a long time, although traditional water-based extinguishing agent is dissolved in water, but water has mobility, after water-based extinguishing agent fire extinguishing with
Water flows away, and cannot generate in battery surface and continue extinguishing effect, cannot accomplish that impregnating battery for a long time is cooled down to prevent from sending out
Raw battery is secondary out of control, and extinguishing effect is poor.Therefore, traditional water-based extinguishing agent is not suitable for fighting power battery heap fire.
The gas extinguishing agents such as traditional heptafluoro-propane only have chemical flame retardant effect, do not have cooling function, for energy storage electricity
Heap this endogenous chemical reaction type hard fire in pond is to play the role of lasting fire extinguishing.Current fire control and extinguishing method is anti-
Malfunction ability is weak, after system malfunction, the extinguishing chemical that vomits may large-scale power supply unit this to energy-storage battery heap cause not
Benefit influences.
Therefore, need to develop now fire extinguishing efficiently, can cool down for a long time inhibits the large-scale energy storage of battery chemistries combustion reaction
Power battery heap fire fire extinguishing system.
