High pressure water mist foam extinguishing agent

Abstract

The invention discloses a high pressure and water mist fire foam which is composed of the raw materials, comprising foaming agent, compound fluorochemical surfactant, penetrant, antifreeze, stabilizer, corrosion inhibitor and water. The weight percentages are as follows: 30-40 percent of foaming agent, 5-10 percent of compound fluorochemical surfactant, 1-5 percent of penetrant, 10-15 percent of antifreeze, 5-8 percent of stabilizer, 0.1-1 percent of corrosion inhibitor and the rest proportion of water. The high pressure and water mist fire foam is a novel multifunctional extinguishing agent with high efficiency and water saving performances and can be equipped on different fire-extinguishing systems. In the water mist praying system, the high pressure and water mist fire foam can spray micro-droplets up to 5-10mm and has high fire-extinguishing efficiency; in the foam fire-extinguishing system, the high pressure and water mist fire foam can produce stable and sustainable foams and is characterized by great performance of separating water and fluidity, and rapid fire-extinguishing speed. The high pressure and water mist fire foam can extinguish both class B fire and class A fire.

Description

Technical field [0001] The invention relates to a fire extinguishing agent, in particular to a multifunctional foam fire extinguishing agent suitable for both a foam fire extinguishing system and a water mist spray system, and can be used for extinguishing class A, B, and C fires. Background technique [0002] With the gradual cessation of production and use of halon fire extinguishing agents worldwide, the search for fire extinguishing agents that can effectively replace halon and that are environmentally acceptable is a hot issue in the international fire protection industry. Fire extinguishing methods and devices, aqueous film-forming fire extinguishing agents, compressed air extinguishing agents, etc. Among the existing water mist spray systems, Chinese patent CN1429638A introduces a portable atomized jet fire extinguisher, CN1180857A introduces a mobile direct high-pressure atomized water mist fire extinguishing device, and CN1480231A introduces an ultra-fine gas Water mist ...

AI Technical Summary

Problems solved by technology

Although the high-pressure water mist fire extinguishing system provides better equipment for fire extinguishing and greatly improves the fire extinguishing efficiency, the effect of the existing fire extinguishing agent used in the high-pressure water mist sprinkler system is not ideal, and the high-pressure water mist spray cannot be fully utilized For the potential of the system, take the high-pressure water mist equipment produced by Forex in Denmark as an example. The foam fire extinguishing agent imported from Norway is used for fire extinguishing of Class B fires. Due to the matching use of the fire extinguishing agent and equipment, the high-pressure water mist equipment cannot be sprayed normally. Foam extinguishes Class B fires, but sprays out the fine water mist beads required to extinguish Class A fires. Due to the same reason, the high-pressure water mist equipment cannot normally spray fine water mist beads for fire fighting of Class B fires.
