Description

Technical Field

[0001] This utility model relates to the technical field of foam fire extinguishing devices, specifically a special anti-arc foam fire extinguishing device for substations. Background Technology

[0002] Currently, the most common and effective method for extinguishing liquid fuel fires is water-based foam. By rapidly spreading a foam layer on the surface of the liquid fuel, it blocks fuel vapor from entering the flame. Water vaporization and liquid precipitation absorb heat, reducing the temperature of the fuel surface and achieving the purpose of rapid fire extinguishing.

[0003] Existing anti-arc foam fire extinguishing devices typically involve directly mixing the foaming agent with water, then pumping the mixture into an annular nozzle assembly to mix with liquid nitrogen, and finally discharging it through a discharge pipe to achieve a cooling effect. However, in this mixing method, the foaming agent, being in block form, requires time to fully mix with the solution, and the forced discharge results in very little foam being sprayed, potentially causing the optimal time for fire suppression to be missed. Therefore, a special anti-arc foam fire extinguishing device for substations is proposed. Utility Model Content
