Description

Three-phase froth coefficient of foaming and pasta system for testing stability
Technical field
The utility model three-phase froth coefficient of foaming and pasta system for testing stability refer to a kind of test device and Its method of testing, specifically, be related to a kind of fire foam foaming effect and foam in pasta Detection of Stability equipment and its The method of detection.
Background technology
Fire foam by good cooling effect, screen effect, smothering effect and be widely used in all kinds of oil products Fire, it can not only quickly cool down combustible surface temperature, moreover it is possible to completely cut off heat radiation of the external heat source to combustible, prevent flammable Thing and air contact, there is good fire extinguishing effect.But fire foam acts on there is also its weak point in fire plume Under, foam is easily broken or dispelled, and when fire scene temperature is higher, foam easily evaporates, it is difficult to reaches pasta, therefore can not fill Its extinguishing effect is waved in distribution.
In recent years, on the basis of two-phase foam add solid phase powder prepared by three-phase froth, preventing and extinguishing fire of coal mine lead Domain extensive use simultaneously achieves good achievement.Three-phase foam extinguishing agent makes full use of the covering effect of solid phase, the heat absorption of water to make Prevented and treated spontaneous combustionof coal with the asphyxia ability with nitrogen or put out a fire, and three-phase froth its skeleton after complete dehydration can still be grown Time is present in goaf, gives full play to its fire extinguishing function, so three-phase froth is used for into mine fire extinguishing significant effect.Grind The person of studying carefully is according to the excellent fire extinguishing performance of three-phase froth, it has been found that its broad prospect of application in oil fire field.
Three-phase froth is applied to oil fire field, the property of foam is most important.Coefficient of foaming and stability are Evaluate two important indicators of foam.Coefficient of foaming is to weigh the index of foam solution foaming capacity, and coefficient of foaming is higher, then identical The foam cumulative volume that amount expanding foam solution is sent is bigger, but jeting effect is poor, and coefficient of foaming is lower, then equal amount foam solution is sent Foam volume is smaller, and jeting effect is preferable.Coefficient of foaming is influenceed by foam solution composition and foam device.The stability of foam can Characterized with altitude rate and analysis liquid speed rate, foam stability is good, then can completely cut off hot spoke of the external heat source to pasta for a long time Penetrate, and contact of the air with pasta can be prevented, play good fire extinguishing and anti-resume combustion effect.Due to the presence of solid-phase component, three The influence factor that the stability of phase foam is subject to is more more than two-phase foam.At present, though in the market has a large amount of measure two-phase foams The device of coefficient of foaming and stability, but the measure coefficient of foaming or stability that it can only be single, and can not measure simultaneously, and It can not be applied to three-phase froth well, can not possibly even measure its stability in actual use.In addition, such device Also stability of the foam in pasta can not be determined, it is impossible to the effect of good reaction foam in actual applications.Thus, it is necessary to Design the device for integrating coefficient of foaming and pasta stability test.
