一、前言目前有两种水幕装置,一种是防止油罐火灾蔓延的固定式水幕装置,一种是保护避难道路的移动式水幕装置。因为形成水幕需要大量的水,所以水幕的使用范围局限在水源比较充足的地方。当水喷雾被风吹动后有时也可能形不成水幕,要弥补这些缺陷,确定城市防止火灾蔓延的有效方法,把水幕和树木同时并用认为是一种比较理想的方法。
I. Preface There are currently two kinds of water curtain devices, one is a fixed water curtain device to prevent the spread of oil fires and the other is a mobile water curtain device to protect evacuation roads. Because the formation of water curtain requires a lot of water, so the use of water curtain is limited to more adequate water source. When the water spray is sometimes blown by the wind may not form a water curtain to make up for these deficiencies to determine the city to prevent the spread of an effective fire prevention method, the water curtain and trees simultaneously considered as a more ideal way.
