Description
Изобретение относитс к способам пожаротушени и может быть использовано дл тушени пожаров в туннел х, коридорах и других помешени х большой прот женности .The invention relates to fire fighting methods and can be used to extinguish fires in tunnels, corridors and other areas of great length.
Целью изобретени вл етс повышение эффективности объемного тушени преимущественно в помещени х большой прот женности за счет снижени сопротивлени продвижению воздушно-механической пены.The aim of the invention is to increase the efficiency of volumetric quenching, mainly in large premises by reducing the resistance to the advancement of the air-mechanical foam.
На чертеже представлена схема защищаемого помещени , продольный разрез.The drawing shows a diagram of the protected room, a longitudinal section.
Помещение имеет проем 1. В нижней части проема 1 дл подачи воды устанавливаетс ручной пожарный ствол, снабженный насадком 2, затем воздущно-пенные стволы 3, а над ними генератор пены или пе- ногенераторна установка 4. Нижн и средн части проема 1 герметизируютс брезентовой перемычкой 5, а верхн часть проThe room has an aperture 1. In the lower part of the aperture 1, a handheld fire barrel is installed with a nozzle 2, then air-foam trunks 3, and a foam generator or foam generator 4 is installed above them. 5, and the upper part is about
ема 1 остаетс открытой дл удалени воздуха и продуктов горени при заполнении объема помещени пеной. Перед началом подачи пены из ствола 2 подаетс распыленна вода, котора снижает температуру в объеме помещени , увлажн ет конструкции стен и оборудование, создает слой воды на полу помещени . По увлажненным поверхност м и слою воды одновременно из воздушно-пенных стволов 3 и генератора 4 подаетс пена низкой и более высокой кратности. Слой воды, увлажнение стен и оборудовани способствует растеканию пены по полу помещени за счет уменьшени сопротивлени ее продвижению. Пена достигает противоположной стены 6, накапливаетс у нее, постепенно заполн весь объем помещени и вытесн продукты горени и воздух через открытую часть проема 1.The emblem 1 remains open to remove air and combustion products when the volume of the room is filled with foam. Before starting the supply of foam from barrel 2, sprayed water is supplied, which reduces the temperature in the volume of the room, moistens the wall structures and equipment, creates a layer of water on the floor of the room. Moisturized surfaces and a layer of water simultaneously supply foam of low and higher expansion from air-foam trunks 3 and generator 4. A layer of water, wetting of the walls and equipment contributes to the spreading of foam on the floor of the room by reducing the resistance to its advancement. The foam reaches the opposite wall 6, accumulates in it, gradually filling the entire volume of the room and displacing the products of combustion and air through the open part of the opening 1.
