CAFS-- compressed air foam fire extinguishing system

Introduction

The "Huayu brand" series of compressed air foam system developed by the company has the advantages of high integration, high automation, complete functions, convenient maintenance, and safe and reliable use. The working medium is water, compressed air and AB foam. Foam extinguishing agents can be classified into type a foam extinguishing agents and B foam extinguishing agents according to their usage and characteristics. B type foam extinguishing agents can be divided into non water-soluble foam extinguishing agents (such as protein foam extinguishing agents, fluorinated protein foam extinguishing agents, "light water" foam extinguishing agents), and anti foam fire extinguishing agents (gel type anti foam fire extinguishing agents, water film forming anti foam fire extinguishing agents, fluorine soluble proteins). Foam extinguishing agent, film forming protein anti foam extinguishing agent, film forming fluorine protein anti foam extinguishing agent, medium multiple anti foam extinguishing agent. It can be selected according to the needs of users. The equipment adopts the integrated and intelligent design concept, with the advantages of automatic flow regulation, accurate and controllable mixing ratio for a long time, low consumption of fire extinguishing media, and significant fire suppression effect. When the system works, the three-phase flow medium quickly generates high quality foam mixture with fine, uniform, stable and unbreakable particles in the pipe network, which is effectively adsorbed on the surface of the combustible material after the output of the terminal jet device, thus achieving a rapid suppression of the scene fire and effectively preventing the fire from re burning. Field test shows that the fixed compressed air foam fire extinguishing device can be fully adapted to the fire protection needs of large fire sites. It is mainly applicable to large oil immersed power transformer, petrochemical industry, ship deck, ship bilge, high-rise building, subway, gas station and other places.

Principle

The high energy storage foam mixture provided by the CAFS system consists of water, foam liquid and compressed air. It not only has the function of heat absorption and isolation, but also can fully refine and foam the foam mixture, enhance the ability to penetrate into the combustion chamber or adhere to the surface of the combustible material, reduce the surface tension of water and increase the specific surface area of water, improve the water permeability and increase the coverage area of water. Thus, the reaction of the combustion chain can be prevented quickly and effectively, the fire extinguishing efficiency can be greatly improved, and the fire extinguishing water can be obviously saved. When the air compressor of the system works independently, it can be used as the air source of emergency rescue equipment, or it can directly spray compressed air to disperse smoke and toxic gas in the fire.
