Description
Technical Field
The invention belongs to a fire extinguishing agent, and particularly relates to a hydrocarbon flammable liquid flowing fire extinguishing agent.
Background
With the rapid development of socioeconomic in China, the petrochemical fire accidents are frequently happened in recent years. 2In 010 years, the explosion of the large oil pipeline causes the crude oil pipeline to break and rapidly form more than 60000m21000 tons of foam extinguishing agent are used for extinguishing the fire. Hydrocarbon liquids such as crude oil, gasoline, diesel oil and the like are flammable and explosive, have high combustion heat value, high fire spreading speed and large storage capacity, and can greatly damage other fuel storage tanks and fire-fighting facilities once leakage and flowing fire occur. After the fire of the hydrocarbon liquid storage tank occurs, once a large-area flowing fire is formed, the fire extinguishing difficulty is extremely high, and meanwhile, the strong heat radiation of the hydrocarbon liquid storage tank can also cause the fire to spread rapidly. Aiming at large-scale inflammable liquid flowing fire, fire rescue teams usually adopt a mode of blocking first and then applying foam for fighting fire. The common foam extinguishing agent is mainly used for extinguishing fire by means of foam covering action in the process of extinguishing large-area inflammable liquid flowing fire, the fire extinguishing speed is low, and the foam reburning resistance performance is poor under the strong heat radiation environment. In addition, although the dry powder fire extinguishing agents disclosed in CN102921139A, CN105879288A, CN103816636A, CN103537039A, etc. can be used for extinguishing large-area flowing fire, the high temperature dangerous characteristic of the fuel is not eliminated, and the anti-reburning performance of such fire extinguishing agents still needs to be further improved.
In order to rapidly extinguish large-area flammable liquid flowing fire, US5945026 discloses a formula and a using method of hydrocarbon fuel capable of extinguishing fire, the formula can reduce the temperature of the fuel and eliminate the flammability of the fuel in an emulsifying and coating mode, and further achieve the purpose of fire extinguishing, leaked fuel can be decomposed by bacteria in water after being emulsified into emulsion liquid drops, and the formula comprises fatty amine polyoxyethylene ether, fatty acid, short carbon chain alcohol and the like. US7223362 discloses a formulation and a method for effectively emulsifying and dispersing petroleum products leaked on the surface of earth/water, the product has the functions of extinguishing fire, removing dirt, accelerating pollutant decomposition and the like, and the effective components of the fire extinguishing agent are nonionic hydrocarbon surfactants such as polyoxyethylene ether sorbitan fatty acid ester, fatty alcohol polyoxyethylene ether and the like. In addition, US4248733 discloses an oil-spill dispersant capable of handling large-area oil spills and also having a fire extinguishing function.
The fire extinguishing agent formula taking the dispersing agent or the emulsifying agent as the main component mainly eliminates fuel flammability by wrapping fuel through emulsification so as to achieve the purpose of fire extinguishing, but emulsion formed after emulsification is still an unstable system, emulsion breaking and fuel separation can be accelerated under the action of heat radiation, and then re-combustion can be generated. In addition, the formula needs to emulsify all the fuel to play a fire extinguishing role, otherwise, the emulsion formed is settled at the bottom of the fuel because the density of the emulsion is higher than that of the fuel, and the oil tank fire with large reserve and thick oil layer is difficult to effectively extinguish.
Disclosure of Invention

the emulsifier is polyoxyethylene octylphenol ether, polyoxyethylene isooctylphenol ether, polyoxyethylene nonylphenol ether, C12-14Fatty alcohol polyoxyethylene ether, C16-18Fatty alcohol polyoxyethylene ether, isomeric decyl alcohol polyoxyethylene ether, isomeric tridecyl alcohol polyoxyethylene ether, isomeric pentadecyl alcohol polyoxyethylene ether, oleic acid triethanolamine, lauric acid triethanolamine, isooctanoic acid triethanolamine, glycerol polyoxyethylene ether ethylhexanoate, sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan monooleate, sorbitan trioleate, sorbitan tristearate, sorbitan monooleate polyoxyethylene ether, sorbitan monolaurate polyoxyethylene ether, sorbitan trioleate polyoxyethylene ether, nonylphenol polyoxyethylene etherAt least one of ether sulfosuccinate disodium salt and fatty alcohol polyoxyethylene ether sulfosuccinate disodium salt.
The invention has the beneficial effects that:
(1) the application scene of putting out a fire is extensive: the fire extinguishing device is particularly suitable for extinguishing hydrocarbon flammable liquid flowing fire, and simultaneously can also be used for extinguishing common hydrocarbon flammable liquid oil tank fire;
(2) the fire extinguishing efficiency is as follows: the fire extinguishing is cooperated through triple effects of emulsified fuel, water film forming isolation, foam coverage and the like, the fire extinguishing effect is rapid, and the re-burning resistance is strong;

(4) PFOS substances are not contained, and the harm to the environment is low;
(5) the preparation process is non-toxic and pollution-free: in the preparation process, various production raw materials are uniformly mixed according to a proportion, and no by-product or waste is generated.
The invention selects the surfactant with the hydrophobic chain length of C8-C18 from the nonionic surfactant and the anionic surfactant as the emulsifier to effectively emulsify the fuel (especially the leaked fuel), and eliminates the flammability of the fuel through the fuel coating and cooling effects, thereby achieving the effect of improving the afterburning resistance and effectively inhibiting the spread of the running fire.
According to the invention, a linear structure surfactant with the hydrophobic chain length of C8-C14 is selected from an anionic surfactant and an amphoteric surfactant as a foaming agent, so that high-stability foam can be effectively formed, the stability of the foam under the action of strong heat radiation of flowing fire is enhanced, the surface tension of a foam solution and the interfacial tension of the foam solution and fuel are reduced, and a water film is promoted to spread on the surface of the fuel.
Because perfluorooctylsulfonyl fluoride, perfluorooctylsulfonic acid and salts thereof (PFOS substances for short) are typical persistent organic pollutants, are changed from the original acceptable use to the specific exemption use by the Stockholm convention and are finally eliminated by China, the invention selectsPerfluorohexyl or partially fluorinated C with low environmental hazard6Or partially fluorinated C8The alkyl chain surfactant is used as the fluorine surfactant, so that the surface tension of the foam solution can be effectively reduced, the foam solution is promoted to rapidly spread on the surface of the fuel to form a water film, the evaporation of the fuel is inhibited, and meanwhile, fluorine surfactant molecules can participate in the arrangement process of a gas-liquid interface, so that the oleophobic capability of the foam is improved.
The emulsifier, the foaming agent and the fluorine surfactant selected by the product are complemented mutually, so that the product has the functions of fuel emulsification, water film formation isolation and foam coverage, overcomes the defect that the emulsion formed by incomplete fuel emulsification of the fire extinguishing agent in the prior art can settle at the bottom of the fuel and further causes re-combustion, and can quickly extinguish the fire which is difficult to extinguish, such as hydrocarbon inflammable liquid flowing fire, oil tank fire with large reserve and thick oil layer, and the like.
According to the invention, the fatty alcohol with the same alkyl chain length as the foaming agent hydrophobic group or the polymer with the tackifying effect is selected from the stabilizer as the stabilizer, so that on one hand, the compactness of the foam surface film can be effectively increased, the strength and the viscosity of the surface film are increased, and the stability of the foam is improved; on the other hand, the mechanical strength and the elasticity of the interfacial film can be improved, the space barrier of an adsorption layer of the interfacial film is increased, the coalescence speed of dispersed phase droplets is reduced, and the stability of the emulsion is enhanced. The use of a co-solvent allows the various components of the product of the invention to be effectively dissolved in aqueous solution, stored for long periods of time and without delamination.
In order to reduce the freezing point of the fire extinguishing agent and ensure that the performance of the fire extinguishing agent is not influenced at low temperature, at least one of ethylene glycol, propylene glycol, glycerol and sodium chloride is selected as an antifreeze agent.
The fire retardant can play a fire extinguishing role by catching free radicals generated in the combustion process of substances, so that the fire extinguishing effect of the fire extinguishing agent is further improved.
The use of the preservative effectively prevents the fire extinguishing agent from being corrupted and deteriorated in the long-term storage process, and prolongs the shelf life of the fire extinguishing agent.
