摘要
细水雾作为哈龙灭火剂的重要替代技术,在电缆隧道中具有广阔的应用前景。然而由于其灭火机理的复杂性,在细水雾灭火系统的设计中不能完全依赖于一般性原则或统一的标准。以浦东国际机场二期工程电缆隧道高压细水雾保护系统的实际应用为例,通过建立全尺度的模拟试验,对细水雾灭火系统设计参数的有效性和科学性进行评估,优化系统设计,以满足电缆隧道特殊的消防安全需求。研究结果表明该方法为细水雾系统设计达到有效性、安全性、经济性的统一提供了合理解决途径。
Water mist, as a substitute of Halon, has widely potential applications in the fire protection of cable tunnel. However, the design of Water mist system cannot follow the general rules due to the complicated fire suppression mechanisms. In this paper, an optimization design and full scale fire test evaluation of Water mist fire suppression system in the Pudong Airport cable tunnel has been established. Full scale fire extinguishing tests are conducted for design validation. Results show that this method provides a reasonable tool to unify the effectiveness, reliability and economics of water mist system design.
