In the oil refining process, generally through a variety of physical or chemical means, through fractions, refined, harmonic processes have a variety of products: gasoline, kerosene, diesel, and liquefied petroleum aromatic hydrocarbons, ethylene, propylene, acetylene and so on. These products are mostly flammable, explosive dangerous goods, low flash and fire, especially in the petrochemical storage process, the external conditions are very complex, influenced by many factors
Fire Accidents can happen easily. Once the tank fire occurred, often forming large area burned, fire spread to a wide range of often is "a can of fire, neighbors calamity", affecting around the tank or building. And the fire lasted longer, fighting the difficulties and huge property losses. Therefore, understanding the petrochemical enterprise risk fire area, effective investigation work to change Fire Tank
Loophole And fire facilities, defect, is to ensure the safety of petrochemical production, storage and transportation of important safeguards.
Ultrafine powder Automatic fire extinguishing system
Ultrafine powder how to control the oil fires: the last century used
Extinguishing agent Most of Halon 1201 and 1301. Its impact on the environment, the destruction of the ozone layer, global warming caused by varying degrees, in 2005 global ban on the use of the type of extinguishing agent. Choose what kind of rapid response, fire fighting and effective, clean, human safety, toxicity, beneficial
Environmental Protection Extinguishing agent, has become a trend.
Fine dry powder extinguishing agent, has excellent fire performance, reflected in the following three aspects:
1, a flame burning strong inhibitory effect.
Flaming is a chain reaction. Combustion of fuel molecules in the formation of high temperature or the energy to be activated under the action, in the presence of oxygen free radicals or active gene, and by the spread of high energy free radical reaction, to maintain continuous combustion. Ultrafine powder mixed with flames, the fire burning components quickly capture free radicals, so that free radicals are consumed faster than the speed of production, burning quickly run out of free radicals, chain reaction process was discontinued, the flame quickly extinguished.
2, choking effect on the surface of burning strong.
Fine powder on the fight against a very good flame burning rate and efficiency, but in general the surface of solid material combustion (smoldering combustion) there is good off the role. When the fine powder crystal powder and burning the burning surface contact, a series of chemical reactions on solid surfaces under high temperature to melt and form a glassy coating the solid surface and ambient air separated from the combustion asphyxia.
3, screen the flame thermal radiation, cooling the protected material.
Use of ultra-fine powder fire extinguishing, the thick cloud-like powder mixed with flames, decomposition endothermic reaction, heat absorbing part of the flame, the decomposition reaction of some non-reactive gases such as: carbon dioxide, water vapor, etc. the oxygen concentration of the combustion zone has a thinning effect, so that the fire weakened the combustion reaction.
Ultrafine powder extinguishing concentration tested through the national inspection department for the 64.4g/m3, is at home and abroad have been invented fire extinguishing agent, extinguishing the lowest concentrations, the highest fire performance, fire the fastest one. Unit volume of Halon fire extinguishing agent efficiency is 2-3 times that of ordinary
Dry powder fire Agent 6-10 times the fire extinguishing agent is more than 10 times, 15 times of carbon dioxide. In addition, the ultrafine powder fire extinguishing agent on the atmospheric ozone depletion potentials (ODP) is zero, the value of greenhouse potential (GWP) is zero, on human skin without stimulation, no corrosion protection materials, non-toxic harmless. Fire residue and easy to clean, can be widely used in various places of production and life to fighting A, B, C class fire equipment, fire and charged.
In the field, the tank fire-fighting experts?? Fine dry powder automatic fire extinguishing system is now in the Shengli Oilfield, Sinopec Wuhan, Jingmen petrochemical, oil and other oil Jianghan
Chemical industry Fields widely used by enterprises at home.
Ultrafine powder fire extinguishing agent in the physical nature of performance as a dry, easy flowing and has good moisture-proof, anti-caking solid powder, easy to store; so it applies not only to total flooding fire extinguishing closed space, but also to places of local application of the open fire. It is reported that Wuhan, god of rain was independently developed by the State Fire Co. test cabinet fine dry powder type automatic fire extinguishing device, the automatic completion of the entire fire-fighting process, no external power supply, 60kg of ABC Dry Powder Extinguishing Agent (by national type examination report) will be able to effectively protect the 300 cubic meters of space. Fire Co., Wuhan, god of rain also developed a new chemical products triethylaluminum special extinguishing agents 'Alkyl Aluminum fire extinguishing agent', which can effectively cope with ABC Dry Powder fire extinguishing agent, integrating high-tech automatic fire extinguishing installations , to the greatest extent that the rapid fire, safety and high efficiency. Is a major petrochemical enterprises in the market the most popular fire-fighting products.
The automatic fire extinguishing device, mainly by total flooding fire-fighting principles. When the tank fire, the tank temperature reaches the nominal operating temperature setting, installed in the tank of the fusible elements melt temperature, the signal passes through thermal lane powder storage tank outside the tank, the tank's boot device to respond in an instant, through the nozzle release of extinguishing agent, will be effectively extinguished the fire in an instant.
Oil field petrochemical industry is a fire-prone industry, the correct selection of fire protection products are the property of the enterprise and the effective protection of personal safety. I am an expert from China Agriculture Net, usually analyzes all kind of industries situation, such as wood drapery hardware , wood curtain rings.
