Abstract
Three-phase foam extinguishing techn is that extinguishing dry powder is added to foaming liquid or airflow and the foam generator produces three-phase foam containing dry powder, which is used to extinguish fire in the oil field. It has comprehensive effects of both foam and dry powder extinguisher, including reducing temp., separating oxygen, choking combustion reaction chain, etc. Here, dry powder is fully-siliconized sodium bicarbonate or ABC dry powder and the foam generator is an improved one with foaming agent being common-used foaming agent and the weight of dry powder counting for 3-20% of total foam weight.
Description
The invention provides a kind of new technology of go out a general solid fire and an oil fire.
Three-phase foam extinguishing technique is not used and report so far both at home and abroad.Foam fire-fighting is one of important measures of modern fire-fighting fire extinguishing, and dry-chemical fire extinguishing also is one of important measures of modern fire-fighting fire extinguishing, and these two kinds of methods all are effectively, but deficiency is also respectively arranged.Fire foam is often stipulated its 25% drain time as its anti-burning index, but still is not enough, to such an extent as to its foaming activity thing water when running into strong fire, when its amount is big inadequately, is not only put out a fire, helps burning on the contrary.Fire-fighting powder also exists the shortcoming that cooling-down effect is poor, fire extinguishing is difficult for thorough, easy resume combustion, and because its granularity is little, is subject to distinguished and admirable, airflow influence, and dispensing effect is not really desirable.
The objective of the invention is to the two advantages of foam fire-fighting and dry-chemical fire extinguishing, have cooling, resistance oxygen simultaneously, suffocate, resist the effect of burning, blocking the combustion reaction chain, a large amount of fast dispensings can be accomplished, large tracts of land oil field boundary fire and general solid fire can be more effectively put out.
The full silicidation fire-fighting powder was generally produced use in recent years.Resembling the such water-insoluble solid particulate of full silicidation fire-fighting powder is harmless to the stability of water base foam, can form the three-phase froth with certain stability under general condition.
The present invention implements fairly simple on existing fire plant level.With in general, low multiple foam maker just can produce with medicament (through modification) in, hang down multiple contain the dry powder three-phase froth, distinguish only be how to introduce dry powder.Two kinds of approach are arranged: the one, dry powder is joined in the bubble solution, stir, (0.5～0.7 MPa) delivers to the foam maker nozzle with pump pressure.The 2nd, with dry powder with the distinguished and admirable foam maker that enters equably.These two kinds of methods can obtain satisfied three-phase froth.The dry powder amount accounts for 3～20% of foam gross weight.
Foaming agent can be special development, also can be improved existing foaming agent.Be used for the water-soluble high-molecular substance of the improved CMC of having, CMS, modified starch, PVA and PAM class, its consumption is 0.1～2.0%(wt).Adding this class material can be to existing various foaming agent, as: albumen, fluorine albumen, modification is carried out in medium expansion foam agent etc., uses as the foaming agent that three-phase froth takes place.
Experiment is given an example:
The ratio that adds the 12g fire-fighting powder with 100ml modification medium expansion foaming agent (using the 0.6%CMC modification), prepare the some liters of foam solution, stir, send into the foaming of medium multiple three-phase froth generator with pump with the pressure of 0.5MPa, foam is contained in φ 350mm, volume is in 301 the lucite bucket, the three-phase froth multiple 30～70 of gained, 25% drainage time＞3min, the small-sized food tray fire extinguishing of half foam life period (V) 〉=2hr. experiment shows, its 90% flame control time, attack time, all is better than the two-phase foam with volume at the anti-burning time.
Claims (6)
1, three-phase foam extinguishing technique is that feature of the present invention is foam fire-fighting and the comprehensive fire-extinguishing technology of dry-chemical fire extinguishing: fire-fighting powder, air (or N
2, CO
2), three kinds of materials of foam solution produce by the three-phase froth generating means in, low multiple three-phase froth, be used to put out a general solid fire and an oil fire.
2,, it is characterized in that referring to the sodium bicarbonate powder of full silicidation or the ammonium phosphate of full silicidation (also being ABC) dry powder according to the fire-fighting powder of claim 1.
3, according to the foam solution of claim 1, it is characterized in that the modifier of finger protein, fluorine albumen, medium expansion foam agent, or in special-purpose, the low expansion foam agent.
4, according to the modifier of claim 1 and claim 3, it is characterized in that referring to that the water soluble polymer thickener by adding CMC, CMS, modified starch, PVA and PAM class carries out the foaming agent of the suitable generation three-phase froth that modification obtains to albumen, fluorine albumen and medium expansion foam agent, addition is 0.1～2.0%(wt).
5, the three-phase froth generating means according to claim 1 is characterized in that: by in general, the low expansion foam generating means improves and to finish, in the feed part dry powder, water and foaming agent are stirred, (0.5～0.7 MPa) delivers to the foam maker nozzle with pump pressure, perhaps dry powder and air mixing, injection enters foam maker.
6, according in the claim 1, low multiple three-phase froth is characterized in that except that the standard of the foam that meets regulations for fire fighting, it is 3～15% of foam gross weight that the medium multiple three-phase froth contains the dry powder amount, and it is 5～20% of foam gross weight that low multiple three-phase froth contains the dry powder amount.
