消防工程施工方案中的泡沫灭火系统设计消防工程施工方案是指在建筑物或其它工程项目中，为保障人们的生命安全和财产利益，采取一系列的措施和技术手段，进行火灾防控的详细计划。
而泡沫灭火系统作为一种重要的灭火装置，被广泛应用于各类建筑工程中。
本文将介绍泡沫灭火系统的设计要点及其在消防工程施工方案中的应用。
一、泡沫灭火系统的设计要点泡沫灭火系统设计是根据建筑物的特点、用途及火灾风险等因素来确定的，其要点主要包括以下几个方面：1.1 确定泡沫灭火系统的类型根据建筑物的用途和火灾风险评估，可以选择适合的泡沫灭火系统类型，如稳态泡沫系统、移动泡沫系统、气体发生器泡沫系统等。
不同类型的泡沫灭火系统有着不同的应用场景和特点，需要根据具体情况进行选择。
1.2 确定泡沫灭火系统的灭火剂比例根据泡沫灭火系统的设计规范和消防技术标准，结合火灾风险评估结果，确定泡沫灭火系统所使用的灭火剂比例。
灭火剂比例的选取要满足灭火效果明显、泡沫的稳定性好等要求，确保在火灾发生时能够迅速有效地进行灭火。
1.3 确定泡沫灭火系统的喷洒方式和区域划分根据建筑物的结构特点和功能分区，确定泡沫灭火系统的喷洒方式和区域划分。
常见的泡沫灭火系统喷洒方式包括喷头式、喷淋式、喷雾式等，要根据具体需求选择合适的喷洒方式。
同时，根据建筑物的布局和使用要求，合理划分泡沫灭火系统的覆盖区域，确保全面覆盖并满足灭火要求。
1.4 确定泡沫灭火系统的控制方式和设备配置根据消防工程施工方案的要求，确定泡沫灭火系统的控制方式和相应的设备配置。
包括控制盘、喷头、压力泵、灭火剂储存罐等设备的配置和参数设置，确保灭火系统能够稳定、可靠地运行，并能够迅速响应火灾事件。
二、泡沫灭火系统在消防工程施工方案中的应用2.1 泡沫灭火系统在建筑物消防工程中的应用泡沫灭火系统作为一种高效的灭火装置，被广泛应用于各类建筑物消防工程中。
例如，大型商业综合体、工业生产车间、地下车库等场所，都需要根据具体情况设计和安装泡沫灭火系统，以应对潜在的火灾风险。

管道水力计算9．2．1 本条参照NFPA 11《低倍数、中倍数、高倍数泡沫灭火系统标准》、BS 5306 Part 6《泡沫灭火系统标准》和现行国家标准《启动喷水灭火系统设计规范》GB 50084规定了泡沫灭火系统管道内的水、泡沫混合液流速和泡沫的流速。
液下喷射灭火系统管道内的泡沫是一种物理性质很不稳定的流体，某些泡沫的25％析液时间为2min～3min，如其在管道内的流速过小、流动时间过长，势必造成部分液体析出，影响泡沫的灭火效果。
因此，在液下喷射系统设计中，在压力损失允许的情况下应尽量提高泡沫管道内的泡沫流速。
较高的泡沫流速，有利于泡沫在流动中的搅拌、混合，减少泡沫流动中的析液。
9．2．2 由于泡沫混合液中水的成分占96％以上，有的高达99％以上，它具有水流体特点，所以在水力计算时，泡沫混合液可按水对待。
式(9．2．2-1)为舍维列夫公式。
1953年，舍维列夫根据其对旧铸铁管和旧钢管所进行的实验提出了该经验公式。
因此，该公式主要适用于旧铸铁管和旧钢管。
式(9．2．2-2)为海澄-威廉公式。
欧、美、日等国家或地区一般采用海澄-威廉公式，如英国BS 5306《自动喷水灭火系统安装规则》、美国NFPA 13《自动喷水灭火系统安装标准》、日本《自动消防灭火设备规则》。
我国现行国家标准《建筑给水排水设计规范》GB 50015、《室外给水设计规范》GB 50013也采用该公式。
为便于比较两计算式计算结果之差异，将式(9．2．2-1)除以式(9. 2．2-2)，所得结果见式(1)。
结合本规范规定，对管径为0．025m～0．2m，流速为2．5m／s～10m／s的情况，计算得(参见图7)：对于普通钢管，1介于1．1292～1．8217之间；对于铜管和不锈钢管，2介于1．8347～2．9600之间。
当系统采用普通钢管时，两个公式的计算结果相差不是很大，考虑到普通钢管在使用过程中由于老化和腐蚀会使内壁的粗糙度增大，进而会增大沿程水头损失。
