轻钢结构厂房消防设计中的独立水幕与防火分区

发布时间:2015-12-3 10:17:57 浏览次数:605
独立水幕防火分隔的。我在医院经常使用的程序的一条防火水幕带区5米宽2米/秒流量。这种划分方式很灵活,防火墙的工厂则为大跨度防火卷帘门是理论上没有多大的跨度,一般正常生产时,它存在有火灾的防火分区时,它能实现及时有效的区分。但是一个人水幕防火分隔。三大问题:
<一>。需要的数量太大,水库高。仍以36米跨度计算、水幕排水量为2升/秒米消防历时两小时而不必为水幕水量비축한다观众历代立方米,而且室内外消火栓的水量该消防储备就可以比较高。
< 2》。水幕开始时,许多水喷出,突然下的昂贵的设备对生产造成较大的损失。如果工厂里发生的一些小火灾,几个灭火器加一支水枪解决,这时不小心开始水幕防火分隔,怕水窗帘的洪水造成的损失,减少一些火灾损失更大。需要更严格的水幕开始时期。它只适合火焰烧半工厂正在蔓延。开始的时候。错铜雀损失为阻止我园林设计工作水幕,大部分可以引进东树洞开始,一般几只依赖口式按摩者开始水幕系统,这是不可信的。
《三》。有效的治疗方法。来检查水幕系统可靠性。理论上,如果车间建筑安装时先安装消防设施重新安装生产设备,总有一天会水幕安装完成,生产设备安装的时候还说水幕。但在工程实践中大多为早日生产生产设备作为最重要的东西,即安装、消防设施。站在后面。那水幕安装完成后,它都永远实际分数情况如何(熟能生巧,大火发生的才能的机会,但如果平时考试)。啊,在关键时刻水幕工作不正常。怎么办。

啊,解决问题技术相似,设计时消防泵室水幕泵的出水口上可设考试水管及阀门帮助孩子平时检查水幕泵工作状态。但是工厂上面水幕管及水幕按摩堵是否,喷泉,毁灭了测试。


Independent water curtain fire barrier. I often use a fireproof water curtain in the hospital program zone 5 meters wide and 2 m / s flow. This method is flexible, the factory is a large span of the fire shutter door is theoretically not much of the span, the normal production, it has a fire fire partition, it can achieve a timely and effective distinction. But a water curtain fire compartment. Three big questions:
< < a >. The amount needed is too large to be high. Still to 36 meters span calculation, water curtain and drainage amount to 2 L / S M fire lasted two hours without cubic meters of ancient water curtain water having arrived audience and the content of indoor and outdoor fire hydrant fire reserves can relatively high.
< 2 >. The water curtain begins, a lot of water jet equipment, expensive suddenly caused larger losses of production. If some small fire happened in the factory, several fire extinguishing device with a gun to solve, then accidentally started fireproof Watercurtain, fear of causing water curtain of flood losses, reduce fire losses greater. The need for more stringent water curtain start period. It is only suitable for flame burning semi factory is spreading. At the beginning. Wrong Dongjak loss to stop my work of landscape design of water curtain, and most can be introduced east tree hole, generally only a few dependent massage mouth began to water curtain system, this is not to be trusted.
"Three". Effective treatment. To check the reliability of water curtain system. Theoretically, if workshop building installation to install fire facilities to re install the production equipment, a day will water curtain installation is complete, production equipment installation time also said water curtain. But in engineering practice most of the early production equipment as the most important thing, that is, the installation, fire facilities. Standing behind. The water curtain installation is complete, it always actual score how (practice makes perfect, fires to the opportunity, but if the usual examination). Ah, not working properly at the critical moment of the water curtain. What to do.
Ah, solving technical problems similar, the design of the water outlet of the fire pump room of pump water curtain can be set up test water pipe and a valve to help children usually check the water curtain pump working condition. But the factory above water curtain pipe and water curtain wall is the fountain, massage, destruction test.
