高压细水雾灭火系统的设计规范与工程应用

来源：http://www.cx-fire.com/ 日期：2026-07-15

高压细水雾灭火系统经过二十余年的发展，已形成较为完善的技术标准体系。《细水雾灭火系统技术规范》（GB50898-2013）是国家层面的核心标准。此外，还有《档案馆高压细水雾灭火系统技术规范》（DA/T45-2021）等行业标准，以及河南等省份发布的地方标准。这些规范对系统的设计、施工、验收及维护管理提出了多维度要求。

After more than 20 years of development, the high-pressure fine water mist fire extinguishing system has formed a relatively complete technical standard system. The Technical Specification for Water Mist Fire Extinguishing Systems (GB50898-2013) is a core standard at the national level. In addition, there are industry standards such as the "Technical Specification for High Pressure Fine Water Mist Fire Extinguishing Systems in Archives" (DA/T45-2021), as well as local standards issued by provinces such as Henan. These specifications provide comprehensive requirements for the design, construction, acceptance, and maintenance management of the system.

高压细水雾灭火系统可用于扑救固体表面火灾、可燃液体火灾、可熔化固体物质火灾以及电气类火灾。但不适用于扑救能与水发生剧烈反应或产生大量有害物质的活泼金属及其化合物的火灾。在具体设计参数方面，开式全室应用系统应用于档案库房时，所保护的单个防护区非常大面积不宜大于1000平方米，体积不宜大于3000立方米。开式分区应用系统的作用面积应为需同时启动相邻分区控制阀对应的保护面积之和。闭式高压细水雾灭火系统的设计参数则根据应用场所类型不同而有所区别。

The high-pressure fine water mist fire extinguishing system can be used to extinguish solid surface fires, flammable liquid fires, meltable solid material fires, and electrical fires. But it is not suitable for extinguishing fires caused by reactive metals and their compounds that can react violently with water or produce large amounts of harmful substances. In terms of specific design parameters, when the open full room application system is applied to the archive warehouse, the maximum area protected by a single protective zone should not exceed 1000 square meters, and the volume should not exceed 3000 cubic meters. The effective area of an open partition application system should be the sum of the protection areas corresponding to the adjacent partition control valves that need to be activated simultaneously. The design parameters of a closed high-pressure fine water mist fire extinguishing system vary depending on the type of application site.

在工程应用领域，高压细水雾灭火系统已在多个重要场景中展现出出众性能。在电力行业，高压细水雾系统对于油浸式电力变压器的灭火效果非常突出，海上电力平台采用高压细水雾和FM200灭火系统相结合的灭火方式，可经济、有效、可靠地控制油类及电气火灾。在交通基础设施领域，终南山隧道管理中心的高压细水雾灭火系统多维度覆盖数据机房、配电室、监控大厅等核心区域，提高了整体消防安全性能，降低了维护成本。在新能源汽车领域，随着动力电池汽车火灾事件增多，高压细水雾已被选取作为动力电池汽车的灭火剂进行研究与应用。

In the field of engineering applications, high-pressure fine water mist fire extinguishing systems have demonstrated excellent performance in multiple important scenarios. In the power industry, high-voltage fine water mist systems have outstanding fire extinguishing effects on oil immersed power transformers. Offshore power platforms use a combination of high-voltage fine water mist and FM200 fire extinguishing systems to economically, effectively, and reliably control oil and electrical fires. In the field of transportation infrastructure, the high-pressure fine water mist fire extinguishing system of the Zhongnan Mountain Tunnel Management Center fully covers key areas such as data rooms, distribution rooms, and monitoring halls, improving overall fire safety performance and reducing maintenance costs. In the field of new energy vehicles, with the increasing number of fire incidents in power battery vehicles, high-pressure fine water mist has been selected as a fire extinguishing agent for power battery vehicles for research and application.

高压细水雾系统还具有环保优势——以水为灭火介质，对环境无污染，适用于有人场所。施加细水雾后氧气体积分数变化幅度较小，非常低为20.62%，不会对人体造成伤害。预作用式细水雾系统还能有效减少水渍损失。这些特性使高压细水雾灭火系统在保护珍贵档案、电子设备等重要资产方面具有不可替代的优势。

The high-pressure fine water mist system also has environmental advantages - it uses water as the extinguishing medium, has no pollution to the environment, and is suitable for places with people. The change in oxygen volume fraction after applying fine water mist is relatively small, with a minimum of 20.62%, and will not cause harm to the human body. The pre action fine water mist system can also effectively reduce water damage. These characteristics make high-pressure water mist fire suppression systems irreplaceable in protecting important assets such as precious archives and electronic devices.
