地铁车站与连接车站的区间形成一个四通八达的网络,气流流向非常复杂。要想在事故区间形成有效通风,单靠设在车站或风井内的大型隧道风机往往达不到通风效果。此时,若能适时采用诱导射流设备,往往能起到事半功倍的效果。结合地铁通风设计,介绍了射流风机和诱导风机系统这两种常用的诱导射流设备的特点、局限性,以及诱导射流设备的选用,探讨诱导射流设备在地铁中的应用。
The metro station and the connection station form a network that extends in all directions and the flow of air is very complicated. In order to form an effective ventilation in the accident zone, large tunnel fans located in the station or air shaft often fail to achieve the ventilation effect. At this point, if timely use of induced jet equipment, can often play a multiplier effect. Combined with the design of metro ventilation, this paper introduces the characteristics and limitations of two commonly used induced jet devices, such as jet fan and induction fan system, as well as the selection of induced jet devices, and discusses the application of induced jet devices in metro.
