Description

Изобретение относится к противопожарной технике.The invention relates to fire fighting equipment.

Известен способ гашения горючих материалов путем передачи на горящий 5 объект с помощью струи воздуха огнегасительного вещества и связующего компонента (11 .There is a method of extinguishing combustible materials by transferring an extinguishing agent and a binder component (11.

Недостаток способа заключается в низкой эффективности гашения матерца-fQ лов пенали. На открытом воздухе пены легко переносятся течением воздуха, а также не предотвращают движение горящей жидкости.The disadvantage of this method is the low efficiency of extinguishing mother-fQ fishing pencil cases. In the open air, foams are easily tolerated by the flow of air, and also do not prevent the movement of a burning liquid.

Целью изобретения является повы- ., шение эффективности гашения. ³ The aim of the invention is to increase the quenching efficiency. ³

Указанная цель достигается тем, что в качестве огнегасительного вещества используют гранулированное минеральное волокно, а в качестве связующего жидкое стекло.This goal is achieved in that granular mineral fiber is used as an extinguishing agent, and liquid glass is used as a binder.

При этом масса жидкого стекла составляет 3-5% массы волокна.The mass of liquid glass is 3-5% of the mass of fiber.

Использование указанных веществ при гашении позволяет повысить эф- 25 фективность гашения не только' горючих жидкостей, но и твердых материалов.·The use of these substances in quenching can increase the quenching efficiency of not only flammable liquids, but also solid materials. ·

На чертеже схематично изображено устройство,реализующее предлагаемый “ способ. 30The drawing schematically shows a device that implements the proposed “method. thirty

По трубопроводу 1 на горящий материал посредством воздушной струи подают’гранулированное минеральное волокно. Через патрубок 2 подают жидкий клей под давлением, который перемешивается с волокном. Смесь обволакивает горящую поверхность 3, при этом толщина покрытия зависит от времени подачи компонентов.A granulated mineral fiber is fed through a pipe 1 to a burning material through an air stream. Through the pipe 2 serves a liquid adhesive under pressure, which is mixed with the fiber. The mixture envelops the burning surface 3, while the thickness of the coating depends on the time of supply of the components.

Пример . Способ реализован при тушении горящего деревянного ограждения размером 5 х 2,5 м. На ограду подают. 2 м³ стекловолокна, в которое добавляют 10 л 33%-ного раствора жидкого стекла. Время тушения 40 с.An example. The method is implemented when extinguishing a burning wooden fence with a size of 5 x 2.5 m. Served on the fence. 2 m ^{3 of} glass fiber, to which 10 l of a 33% aqueous glass solution are added. Extinguishing time 40 s.

Способ гашения может быть использован для тушения любых материалов, кроме того, может быть использован для предотвращения от загораний объектов, расположенных по соседст-⁴ву, так как слой, минерального волокна со связующим компонентом обладает изолирующими свойствами.The extinguishing method can be used to extinguish any materials, in addition, it can be used to prevent objects located adjacent to ⁴ from being sunburned, since a layer of a mineral fiber with a binder component has insulating properties.

Claims

FIELD: fire protection engineering. The known method of extinguishing combustible materials is carried out by transferring an object to the mountains by means of a jet of air to the fire of the extinguishing vice and the binder component fl. The lack of sport is the low efficiency of quenching of the case. In the open air, foams are easily transported by the flow of air and do not prevent the movement of burning liquid. The aim of the invention is to increase the efficiency of quenching. This goal is achieved by using granulated mineral fiber as an extinguishing agent, and using liquid glass as a binder. At ums, the mass of liquid glass is 3-5% of the mass of the fiber. The use of these substances in quenching allows one to increase the quenching efficiency of not only hot liquids, but also solid materials. The drawing schematically shows a device that implements the proposed method. Pipeline 1 supplies granulated mineral fiber to the burning material by means of an air jet. Through the nozzle 2, a liquid adhesive is fed under pressure, which is mixed with the fiber. The mixture envelops the burning surface 3, while the thickness of the coating depends on the time of delivery of the components. An example. The method is implemented when extinguishing a burning wooden fence measuring 5 x 2.5 m. The fence is served. 2 m glass fiber to which is added 10 l of 33% aqueous solution of liquid glass. Stew time 40 s. The quenching method can be used to extinguish any materials, in addition, it can be used to prevent objects located in the vicinity from igniting, since the layer of mineral fiber with a binder component has insulating properties. Claim 1. Method of quenching combustible materials by transferring to a burning object from

using a jet of air extinguishing agent and a binder component, characterized in that, in order to increase the quenching efficiency, granulated mineral fiber is used as the extinguishing agent, and liquid glass is used as a binder.

2. The method according to claim 1, characterized in that the mass of liquid glass is 3-5% of the mass of the fiber.
