Abstract
A high-fluorine foam fire-extinguishing chemical resistant to dirt and seawater contains hydrolytic protein solution, ampholytic surfactant, anionic surfactant, foam stabilizer (ferrous sulfate), anticorrosion agent and antipolar solvent (aqueous solution of xanthan gum). Its advantage is that the existing processing water of oil field can be used to extinguish fire.
Description
Technical field
The present invention relates to a kind of fire control and disaster rescue fire extinguishing with medicament, especially be suitable for a fire foam of handling water that recovers the oil.
Background technology
Existing fire foam, it mainly is made up of blowing agent, mixed surfactant, the hydrosol, solubilizer, antifreeze and anticorrisive agent.And 1. the water after the water treatment of recovering the oil contain a large amount of strong electrolytes, as magnesium chloride, calcium chloride, sodium thiosulfate, potassium chloride etc., 2. demulsifier has been adopted in the oil recovery field in water treatment procedure, water after the processing contains residue, and 3. the greasy dirt that contains in the sewage forms oleic acid, halo stearic acid in the natural degradation process of microorganism.They all are the very strong anion surfactants of surface-active, act as demulsifier, in the foam fire-fighting agent solution, contain 0.1% content when their mixture and will produce tangible froth breaking effect foam, on foam wall, squeeze away the foaming molecule, reduce surface tension, make that the arrangement of foam is loose, reduced the stability and the persistence of foam, quicken bleed and broken bubble, until lather collapse; When the foaming of foam solution premix was put out a fire, because the effect of greasy dirt and oleic acid, at appearance formation one deck oil film of foam, in fire extinguishing, the foam oil film was just followed nature, reduces fire-fighting efficiency, and the quickening foam is aging; Because the effect of strong electrolyte, the colloidal sol in the foam solution condenses, and until sedimentation, has changed the composition proportioning of extinguishing chemical.This shows that the regular-type foam extinguishing chemical can not come fire preventing with a processing water that recovers the oil.For fire preventing, reduce the loss that fire brings, an employing of recovering the oil is at present laid in a large amount of fresh water, is built pond, pipeline related facility, has caused great waste.
Summary of the invention
In order to overcome the deficiency that existing fire foam exists, the invention provides a kind of high fluorine anti-soil sea water resistance fire foam, this extinguishing chemical can utilize to recover the oil and have the fire preventing of recovering the oil of water after the processing now, reduces the loss that fire brings.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the hydrolyzed protein liquid, 0.5-20% amphoteric surfactant, 0.1-1.0% anion surfactant, 0.5-20% foam stabiliser, the anticorrisive agent of 0.1-1.0%, the anti-polar solvent of 10-20% of 60-80%, wherein foam stabiliser is a ferrous sulfate, and anti-polar solvent is the former glue solution of sulphur.When this fire foam combined fire extinguishing with a processing water that recovers the oil, hydrolyzed protein liquid, amphoteric surfactant, anion surfactant and anti-polar solvent mixed liquor played inhibitory action to strong electrolyte.Demulsifier can be by the solubilization of amphoteric surfactant institute, thereby loses the effect of froth breaking.Amphoteric surfactant and anion surfactant not only can make foam can form a kind of moisture film on the surface of water-insoluble fuel, and foam is sprawled rapidly; Greasy dirt is formed the oil-in-water state, and greasy dirt is wrapped in the foam, and greasy dirt can not spontaneous combustion, improves fire-fighting efficiency; And in polar solvent, form a kind of immobilon-p, stoped in the sewage small amount of polar solvent effectively the water sorption of foam.
The specific embodiment
65% animal hydrolyzed protein liquid, 15% amphoteric surfactant, 0.1% anion surfactant, 1.0% ferrous sulfate, 0.5% anticorrisive agent, 18.4% the former glue solution of sulphur are mixed reaction after 1 hour under 40-75 ℃, normal pressure, sedimentation in reactor.
Claims (1)
1, a kind of high fluorine anti-soil sea water resistance fire foam, it is characterized in that: comprise the hydrolyzed protein liquid, 0.5-20% amphoteric surfactant, 0.1-1.0% anion surfactant, 0.5-20% foam stabiliser, the anticorrisive agent of 0.1-1.0%, the anti-polar solvent of 10-20% of 60-80%, wherein foam stabiliser is that ferrous sulfate, anti-polar solvent are the former glue solution of sulphur.
