摘要

气体灭火剂因其灭火效率高、灭火性能优越、对被保护对象的损害有限而受到广泛关注。以往的尝试主要集中在单一气体灭火剂的灭火效果上,对气体灭火剂与不同灭火剂的协同使用总结较少。本研究对典型的气体灭火剂及其协同灭火效果进行了严格审查,包括 Novec1230、氢氟碳化合物(HFCs)、惰性或非活性气体等。众所周知,不同灭火剂的协同使用可以弥补单一灭火剂在物理或化学灭火中的不足,减少灭火剂的使用量和有毒物质的产生,提高混合系统的灭火效率。气-气协同(如 Novec1230-C6F15N 或 Novec1230-CO2)可抑制某些气态灭火剂在低浓度下的可燃性,增强混合体系的阻燃和抑爆效果。气液协同(如 Novec1230-水雾或 HFC-227ea-水雾)兼顾了快速灭火和冷却保护对象的作用。气固协同(如 HFC-227ea-SiO2 干粉或 N2-ABC 干粉)在一定程度上弥补了干粉灭火剂覆盖面小的缺陷,达到快速、低污染灭火的目的。本综述为高效、清洁地使用灭火剂以及潜在的未来方向提供了指导和建议。

Synergistic effects of typical clean gaseous fire-extinguishing agents

Gaseous fire-extinguishing agents have received widespread attention due to their high efficiency, excellent extinguishing performance, and limited damage to protected objects. Previous attempts have mainly focused on the fire-extinguishing effect of single gaseous fire-extinguishing agents, where the synergistic use of gaseous extinguishing agents with different extinguishing agents has been less summarized. This study critically reviewed typical gaseous fire-extinguishing agents and their synergistic extinguishing effects, including Novec1230, hydrofluorocarbons (HFCs), inert or inactive gases, etc. It was known that the synergistic use of different extinguishing agents could compensate for the shortcomings of a single agent in physical or chemical fire extinguishing, reduce the amount of extinguishing agent used, the production of toxic substances, and improve the efficiency of the mixed system of fire extinguishing. Gas-gas synergy (e.g., Novec1230-C6F15N or Novec1230-CO2) can inhibit the flammability of some gaseous extinguishing agents at low concentrations and enhance the flame retardant and explosion suppressant effects of the mixed systems. Gas-liquid synergy (e.g., Novec1230-water mist or HFC-227ea-water mist) considers both the roles of rapid fire suppression and cooling of the protection object. To a certain extent, gas-solid synergy (e.g., HFC-227ea-SiO2 dry powder or N2-ABC dry powder) makes up for the poor coverage of dry powder fire extinguishing agents to achieve rapid and low-pollution fire extinguishing goals. This review offers guidance and suggestions for the efficient and clean use of extinguishing agents and the potential future direction.

期刊介绍: Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
