Abstract
The invention provides a dry powder extinguishing agent using expansible graphite as a main material; the dry powder extinguishing agent comprises the main material and additives, wherein the main material is graphite which is expansible when being heated; and the additives are anti-blocking agent, inert adding component and so on. According to the invention, the heat insulating efficiency and anti-burnback performance of the dry powder extinguishing agent during extinguishing large-area pool fire and flowing fire can be enhanced, and spread rate and scale of a fire disaster mainly caused by thermal radiation are effectively reduced.
Description
Technical field
The present invention relates to extinguishing chemical, particularly a kind of inflatable type powder extinguishing agent be used to put out a fire to save life and property large tracts of land oil sump fire and trickling fire.
Background technology
Along with the fast development of Chinese energy safety implementation and economic society, large-scale petroleum storing tank district and the Large Scale Oil Storage Tank of China are on the increase, and potential large tracts of land oil sump fire and spill fire accident risk are also in continuous increase.From Huang Island oil depot fires in 1989 to 2010 Talien New Port fire in oil pot sites, the tank field fire that constantly takes place frequently has caused serious casualties, property loss and ambient influnence.In case the tank farm breaking out of fire very easily forms large-area pond fire and trickling fire, if flame can not get controlling timely and effectively, its strong heat radiation will cause fire to spread fast, form the sea of fire, cause catastrophic effect.The use of extinguishing chemical plays key effect in the fire attack of tank field.At present, for large tracts of land oil sump fire and trickling fire, mainly adopt fire foam and powder extinguishing agent to put out a fire to save life and property.From practical effect, two kinds of extinguishing chemicals cut both ways.Existing powder extinguishing agent has advantages of that blow-off velocity is fast, but its burn resistance and anti-resume combustion at the large tracts of land oil fire of putting out a fire to save life and property is poor, the fire extinguishing weak effect; Existing fire foam has preferably covering, heat insulation and temperature reduction performance, but blow-off velocity is relatively slow in large tracts of land oil sump fire and trickling fire, and the burn resistance of foam under the heat-flash radiation condition is poor, froth breaking is fast, only have the very large supply intensity of employing just can reach fast the effectively requirement of fire extinguishing, need simultaneously to possess enough water sources and ensure, these factors have all limited its effective use.At present, the method with dry powder and foam coupling is arranged in actual combat, namely utilize the quick flame arrest compacting intensity of a fire of dry powder, re-use foam and in time cover, this method is compared with independent use fire extinguishing has certain advantage.But the difficulty that tactics cooperate and the cooling of the foam behind the dry powder flame arrest are subjected to the impact of the factors such as fire scale, except initial fire disaster, generally are difficult to the effect that reaches good.
Summary of the invention
The problem to be solved in the present invention is heat-insulating efficiency and anti-resume combustion performance that the raising powder extinguishing agent is puted out a fire to save life and property large tracts of land oil sump fire and trickling fire, the fire spread speed and the scale that effectively stop heat radiation to be dominated.
The approach that addresses this problem is exactly to adopt a kind of powder extinguishing agent take expansible graphite as major ingredient, can effectively improve powder extinguishing agent to covering power, reduction flame thermal radiation power, the anti-resume combustion characteristic of raising of oil product.Powder extinguishing agent take expansible graphite as major ingredient of the present invention forms and comprises: major ingredient, and expansible graphite is heated; Additive, anticaking agent and inertia are added component etc.This powder extinguishing agent of the present invention is used for putting out a fire to save life and property of large tracts of land oil sump fire and trickling fire.
Powder extinguishing agent take expansible graphite as major ingredient of the present invention, the particle diameter of the extinguishing chemical of selecting distribute and are: the 70-200 order.
Powder extinguishing agent take expansible graphite as major ingredient of the present invention, anticaking agent are selected from least a in the following material: methyl-silicone oil, ethyl silicon oil etc.
Powder extinguishing agent take expansible graphite as major ingredient of the present invention, inertia add component and are selected from least a in the following material: expanded vermiculite, perlite, magnesite, talcum, atlapulgite, calcium hydroxide etc.
Powder extinguishing agent take expansible graphite as major ingredient of the present invention, it contains the 70-90% quality and divides, the expansible graphite that preferred 75-85% quality is divided; The 1-15% quality is divided, the anticaking agent that preferred 5-10% quality is divided, and the 1-15% quality is divided, and the inertia that preferred 5-15% quality is divided is added component, and the total amount of these compositions is 100%.
Expansible graphite is as powder extinguishing agent, can effectively improve the existing poor shortcoming of the anti-resume combustion of powder extinguishing agent, and the expanded by heating characteristic is arranged, fire scale is larger, temperature is higher, more can strengthen effect of heat insulation, reduces rapidly the heat radiation power in the scene of a fire, dispose and cooling covers precondition is provided for the scene of a fire, this novel inflatable powder extinguishing agent will become the certainty of fire-fighting technique core.
The specific embodiment
Embodiment 1: a kind of powder extinguishing agent take expansible graphite as major ingredient comprises the expansible graphite that 80% quality is divided; The methyl-silicone oil that 5% quality is divided, the atlapulgite that 4% quality is divided, the talcum powder that 4% quality is divided, the calcium hydroxide that 7% quality is divided, total amount is 100%.
Embodiment 2: a kind of powder extinguishing agent take expansible graphite as major ingredient comprises the expansible graphite that 85% quality is divided; The methyl-silicone oil that 5% quality is divided, the atlapulgite that 5% quality is divided, the talcum powder that 2% quality is divided, the perlite that 3% quality is divided, total amount is 100%.
