Multifunctional water film foam fire extinguishing equipment

Technical Field

The utility model relates to the technical field of fire fighting equipment, in particular to multifunctional water film foam fire extinguishing equipment.

Background

An aqueous film-forming foam extinguishing agent (AFFF for short) is an environment-friendly film-forming foam extinguishing agent which is mainly prepared from a fluorine surfactant, a foaming agent and the like and is a light yellow transparent liquid. The fire disaster of nonpolar or hydrocarbon fuel is extinguished after the mixture of the foam tank (foam proportion mixing device) and water according to the proportion concentration of 3 percent and 6 percent. Can be used in combination with compatible dry powder extinguishing agents and can be used with most foamed foams in extinguishing fires. The water separated out from the foam layer of the water-film-forming foam liquid in the fire extinguishing process can form a water film with good sealing property on the surface of the fuel, so that the contact between the fuel and air is isolated, and oil fires can be quickly and efficiently rescued by virtue of the dual functions of foam and a protective film. It is characterized by low energy consumption and only needs very small stirring energy. The generated foam has excellent fluidity and can quickly press down the flame to extinguish the oil fire.
