First, ultra-fine powder introduction
Fire extinguishing agents used in the last century were mostly halon 1201 and 1301. At the time, it was thought that Halon 1301 is the best flame inhibitor for a variety of different types of fire. However, by the mid-1980s, people gradually came to realize its impact on the environment, its damage to the atmospheric ozone layer and its global warming to varying degrees. The Montreal Agreement was introduced in Canada in 1993 to limit the production of ozone-depleting substances, And stipulates that the global ban on the use of 2005. What kind of quick response, fire extinguishing effective, clean, safe, toxic, environmentally friendly extinguishing agents, has become a top priority.
Superfine powder efficient fire extinguishing agent, with excellent performance. Its outstanding fire performance, reflected in the following three areas:
1, strong inhibition of flaming combustion.
Flaming combustion is a chain reaction. The fuel molecules are activated at high temperatures of combustion or the energy they form to generate free radicals or active genes in the presence of oxygen and rely on these free radical propagating reactions with high energy to sustain the ongoing combustion. Ultrafine powder mixed with the flame, the fire extinguishing components quickly capture free radicals, so that the rate of consumption of free radicals is greater than the speed of production, combustion of free radicals quickly depleted, the chain reaction process is terminated, the flame quickly extinguished.
2, the surface burn strong suffocation role
Ultrafine dry powder has a very good rate and efficiency for extinguishing flaming and good extinguishing effect on the surface combustion (smoldering) of general solid materials. A series of chemical reactions take place when the powder of ultrafine powder crystals comes into contact with the surface of a burning combustion product, is melted by the high temperature of the solid surface and forms a glassy coating separating the solid surface from the surrounding air, asphyxia.
3, the thermal radiation shielding and cooling effect.
The use of ultra-fine powder fire extinguishing, dark clouds of powder and flame mixed, decomposition of endothermic reaction, can absorb some of the heat of the flame, these decomposition reaction of some of the inert gases such as: carbon dioxide, water vapor, the combustion zone The oxygen concentration has a dilution effect, so that the combustion reaction of the fire is weakened.
Extinguishing concentration of ultrafine powder fire extinguishing agent tested by the national inspection department for the 64.4g / m3, is the current fire extinguishing agent at home and abroad has been found to have the lowest fire extinguishing concentration, the highest fire extinguishing efficiency, the fastest fire extinguishing speed. The unit volume of fire extinguishing efficiency is 2-3 times that of halon fire extinguishing agent, 6-10 times of that of ordinary dry powder fire extinguishing agent, 10 times more than that of heptafluoropropane fire extinguishing agent and 15 times that of carbon dioxide.
In addition, ultrafine powder fire extinguishing agent has zero ODP (Atmospheric Ozone Depletion Potential) and zero GWP, which is non-irritating to human skin and non-corrosive to protectants. After the fire extinguishing residue easy to clean, can be widely used in various places of production and life, to fight A, B, C fire and charged equipment fire. The fire extinguishing agent identified by the national science and technology department is a domestic initiative, is currently in the world's leading level.
Second, ultra-fine dry powder fire extinguishing device
In the petroleum refining process, various products are generally obtained through various physical or chemical methods through the steps of fractionation, refinement and reconciliation: gasoline, kerosene, diesel oil, petroleum aromatics and liquefied gas, ethylene, propylene, acetylene Wait. These products are mostly flammable, explosive dangerous goods, flash point and ignition point is low, especially in the storage of petrochemical products, the external conditions are complex, more influencing factors, fire accidents prone. In the event of a fire in a tank farm area, large-scale combustion often occurs. The scope of the fire is very wide. Often it is "a can of fire and neighbors are plagues," affecting the surrounding storage tanks or buildings. And the fire lasted a long time, fighting difficulties, huge loss of personnel and property.
As of 8:05 on June 28, PetroChina Lanzhou Petrochemical Company refinery leaks due to the gas fractionation device 507 heat exchanger head cover, as in the early days of the fire did not effectively control the automatic fire extinguishing device eventually led to a serious fire ACCIDENT. Fire fighting rescue process, a corporate firefighter sacrifice, six firefighters severe burn, four firefighters moderate burn.
Therefore, understanding the danger of fire in storage tank area of petrochemical enterprises, effectively checking the fire fighting work holes and fire facilities in the storage tank area is an important guarantee to ensure the safe production, storage and transportation of petrochemical enterprises.
