Abstract
Изобретение относитс к области противопожарной техники, в частности к способам тушени пожаров нефтепродуктов, хран щихс в резервуарах и позвол ет повысить эффективность тушени . При возникновении пожара в резервуаре операторы от пожарного автомобил по рукавной линии 2, подсоединенной к узлу 3, подают раствор пенообразовател в трубопровод 4, а затем - к генераторам воздушной пены 5. После формировани струи пены открывают замок 6 и под действием противовеса 7 трубопровод 4 перемещаетс в верхнее положение. При этом положении осуществл ют подачу пены вдоль стенки резервуара. Одновременно с этим осуществл ют подачу воздуха через трубопровод 13, который устремл етс к поверхности горени в зону подачи пены. Газ, выход на поверхность нефтепродукта, способствует растеканию пены по всей его поверхности, благодар чему значительно сокращаетс врем тушени и расход пенообразовател . 1 ил.The invention relates to the field of fire fighting equipment, in particular to methods for extinguishing fires of petroleum products stored in tanks and allows for an increase in the efficiency of extinguishing. In the event of a fire in the tank, the operators from the fire truck follow the hose line 2 connected to node 3, supply the frother solution to the pipe 4, and then to the air foam generators 5. After the foam jet is formed, lock 6 is opened and under the action of the counterweight 7 the pipe 4 moves in the upper position. In this position, foam is fed along the wall of the tank. At the same time, air is supplied through conduit 13, which rushes to the burning surface in the foam supply zone. The gas exiting to the surface of the oil product promotes the spreading of the foam over its entire surface, due to which the quenching time and the foaming agent consumption are significantly reduced. 1 il.
Description
Изобретение относится к способам тушения пожаров нефтепродуктов, хранящихся в резурвуарах.The invention relates to methods for extinguishing fires of petroleum products stored in the tanks.
Цель изобретения — повышение эффективности тушения.The purpose of the invention is to increase the efficiency of extinguishing.
На чертеже представлена схема устройства для реализации способа тушения пожара.The drawing shows a diagram of a device for implementing the method of extinguishing a fire.
При возникновении пожара в резервуаре 1 операторы от пожарного автомобиля но рукавной линии 2, подсоединенной к узлу 3, подают раствор пенообразователя в трубопровод 4, а затем и к генераторам воздушной пены 5. После формирования пенных струй открывают замок 6 и под действием противовеса 7, через двухплечевые рычаги 8 относительно осей 9, закрепленных на кронштейнах 10, трубопровод 4 перемещается в верхнее положение. При этом положении осуществляется подача пены вдоль стенки резервуара. Одновременно с этим подсоединяют к соединительной головке 1 1 шланг, по которому от компрессора или баллона через предварительно открытый вентиль 12 и трубопровод 13 подают газ, который, приоткрывая клапан 14, устремляется к поверхности горения в зону подачи пены. Газ, попадая под слой пены, способствует ее 5 быстрому растеканию в сопутствующем направлении с верхним слоем нефтепродукта. Благодаря чему значительно (в 3—4 раза) сокращается время на ликвидацию пожара и сокращается расход пенообразователя.In the event of a fire in the tank 1, the operators from the fire truck but the hose line 2 connected to the unit 3, supply the foaming solution to the pipeline 4, and then to the air foam generators 5. After the formation of the foam jets, the lock 6 is opened and under the influence of the counterweight 7, through two-arm levers 8 relative to the axes 9, mounted on the brackets 10, the pipe 4 is moved to the upper position. In this position, foam is supplied along the wall of the tank. At the same time, a hose is connected to the connecting head 1 through which a gas is supplied from the compressor or cylinder through a pre-opened valve 12 and pipe 13, which, opening the valve 14, rushes to the combustion surface in the foam supply zone. Gas, falling under the foam layer, contributes to its 5 rapid spreading in the concomitant direction with the upper layer of the oil product. Due to this, the time to eliminate the fire is significantly (3-4 times) reduced and the consumption of a foaming agent is reduced.
