大中型载人潜水器用灭火介质选择分析

Selection and Analysis of Fire Extinguishing Media for Large and Medium Manned Submersible

在参考现有国外大中型载人潜水器的结构与布置基础上,分析了大中型载人潜水器可能存在的火灾隐患及其火灾特点。结合大中型载人潜水器的实际灭火需求,以及灭火效能、灭火经济性、对保护对象安全性等角度,综合论述了各类灭火介质的优缺点。为将来大中型载人潜水器及类似水下平台的灭火系统设计,尤其是如何合理选取灭火介质方面提供了思路及参考。

On the basis of referring to the structure and layout of existing large and medium -sized manned submersible abroad, the author analyzed the possible related fire hazards and fire characteristics, summarized the advantages and disadvantages of various fire extinguishing media depending on the actual fire suppression demand of the submersible, the efficiency and economy of suppression and the safety of the protected object so as to provide ideas and references for the design of fire extinguishing system for large and medium manned submersible and similar underwater platforms in the future, especially for choosing fire extinguishing media reasonably.
