大面积厂房消防排烟设计

本文对大部分靠人工照明,无自然排烟的大面积厂房,采用每平方米15m~2/h～30m~3/h的排烟风量进行消防排烟系统设计。并针对工艺管道布置复杂,将各防火分区的排烟风管布置成各种形式。设计中还对风管穿外墙缝隙处渗水等问题进行了处理。

The Smoke-proof/evacuation Design in Large Space Industrial Building

The paper is about the design of smoke-proof/ evacuation system in the most large space industrial buildings with artificial illumination but without natural smoke evacuation system. The design air rate of the smoke evacuation is 15m3/h/m2-30m3/h/m2. In view of the complex distribution of the technological pipes, the smoke duct in every fire compartment is designed in various forms. The design also solves the problem of water leakage when air pipes pass through the external wall.
