我们在日常生活中使用了许多消防排烟管道。消防排烟系统本身属于公众的重要对象。但是,对消防排烟和通风管道的要求也很高。一般来说,严格来说,在选择防火排烟和通风管道时,首先考虑的是阻燃性。我们都知道,消防工作在高温甚至明火的环境中进行,因此需要考虑通风管道的耐火性和阻燃性。不过消防排烟管道是否又需要防火保温呢?
We use many fire smoke exhaust pipes in our daily life. The fire smoke exhaust system itself belongs to the important object of the public. However, the requirements for fire smoke exhaust and ventilation pipes are also very high. Generally speaking, strictly speaking, when selecting fire, smoke exhaust and ventilation ducts, the first consideration is flame retardancy. As we all know, fire fighting work is carried out in the environment of high temperature or even open fire, so the fire resistance and flame retardancy of ventilation pipes need to be considered. However, does the fire smoke exhaust pipe need fire prevention and insulation?
1、 排烟管可以保温,因为根据相关要求,特别是一些排烟管,周围温度可能比较高。如果不能满足设置要求,应结合管道间距采取保护措施。如果不能满足20cm的要求,则需采取保温保护。
1. The smoke exhaust pipe can be insulated, because according to relevant requirements, especially some smoke exhaust pipes, the surrounding temperature may be relatively high. If the setting requirements cannot be met, protective measures shall be taken in combination with the pipe spacing. If the requirement of 20cm cannot be met, thermal insulation protection shall be taken.
2、 有些排烟管不需要隔热处理。如果其他条件满足要求,也能在室外排放室内烟气,则无需再做保温处理,也无需安装普通排气管。
2. Some smoke exhaust pipes do not need heat insulation. If other conditions meet the requirements and indoor flue gas can be discharged outdoors, there is no need to conduct thermal insulation treatment or install ordinary exhaust pipe.
事实上,消防排烟管道需要防火保温处理,这对于在使用过程中有着重要的作用价值。
In fact, the fire exhaust pipe needs fire protection and thermal insulation treatment, which plays an important role in the use process.
如何控制地下室排风排烟共用风口? 电气上是否能控制不同防烟分区的风口关闭?当火灾呗确认后,应能开启排烟区域的排烟口和排烟风机,并自动关闭与排烟无关的通风、空调系统。
How to control the common air outlet of basement exhaust and smoke exhaust? Can you electrically control the closing of air vents in different smoke prevention zones? When the fire is confirmed, it shall be able to turn on the smoke outlet and smoke exhaust fan in the smoke exhaust area, and automatically turn off the ventilation and air conditioning system irrelevant to smoke exhaust.
1、多个排烟分区合用排烟排风系统,这种情况的话,电动阀+排烟风口更好,平时常开排风,着火关闭非着火点排烟分区的设置在支管上的电动阀,超过280度风口熔断关闭,烟气如扩散到其他防烟分区则开启此防烟分区支管上的电动阀
1. Multiple smoke exhaust zones share the smoke exhaust system. In this case, the electric valve + smoke exhaust outlet is better. Usually, the exhaust is always open, and the electric valve set on the branch pipe of the smoke exhaust zone without ignition point is closed on fire. If the air outlet exceeds 280 degrees, it is fused and closed. If the smoke diffuses to other smoke prevention zones, open the electric valve on the branch pipe of this smoke prevention zone
2、一般住宅的地下室为储藏功能,并划分为小的储藏间,排烟排风系统合用,一套系统也就负责1个或者2个防烟分区,并且烟气扩散很快,阀门来回开启与关闭,采用全部敞开的排烟风口比较好,平时常开排风,着火也全部开启,超过280度关闭。
2. Generally, the basement of a residence is used for storage and is divided into small storage rooms. The smoke exhaust system is shared. A set of system is responsible for one or two smoke prevention zones, and the smoke diffuses quickly. The valves are opened and closed back and forth. It is better to use all open smoke exhaust outlets. It is usually open for exhaust, and all fire are opened, and closed at more than 280 degrees.
