Description
Обычным средством тушени масел и масл нистых жидкостей вл етс пена, образованна углекислым газом и водным раствором, содержащим пенообразователь .A common means of extinguishing oils and oily liquids is foam formed by carbon dioxide and an aqueous solution containing a foaming agent.
Так как температура гор щих масел всегда выше 100°, то водна пена, проника под поверхность масел, превращаетс в перегретый пар, вытесн ющий гор щее масло через кра хранилища в виде гор щей пены.Since the temperature of the burning oils is always higher than 100 ° C, the aqueous foam, penetrating under the surface of the oils, turns into superheated steam, displacing the burning oil through the edges of the store in the form of burning foam.
По предлагаемому способу дл тушени гор щих масел и других легких жидкостей действуют при помощи пены, образованной из этих же масел.According to the proposed method for extinguishing burning oils and other light liquids, they act with the help of foam formed from the same oils.
Дл получени пены из соответствующего масла необходимо к этому маслу прибавить соды (бикарбонат) и концентрированной с/ерной кислоты уд. в. 1,84 в следующих пропорци х: 100 кг масла, 20 Kt соды, 13,8 кг кислоты.To obtain a foam from the corresponding oil, it is necessary to add soda (bicarbonate) and concentrated hydrocarbon acid to this oil. at. 1.84 in the following proportions: 100 kg of oil, 20 Kt of soda, 13.8 kg of acid.
Практически способ осуществл етс следующим образом. В огнетушитель, снабженный сифонной трубкой, баллоном со сжатым воздухом и ампулой дл кислоты, наливаетс масло, заранее смешанное с соответствующим количеством бикарбоната. В момент пожара открываетс вентиль, впускаетс сжатый воздух дл перемешивани соды,In practice, the method is carried out as follows. An oil extinguisher mixed with an appropriate amount of bicarbonate is poured into a fire extinguisher equipped with a siphon tube, a balloon with compressed air and an ampoule for an acid. At the time of the fire, the valve opens, compressed air is let in to mix the soda,

котора за врем хранени опустилась на дно, и разбиваетс ампула с кислотой.which, during storage, has sunk to the bottom, and the ampoule with the acid is broken.
При взаимодействии бикарбоната натри с серной кислотой выдел етс углекислый газ, превращающий все масло в плотную пену, котора под давлением выдел емого углекислого газа за счет реакции и под давлением сжатого воздуха наноситс на поверхность гор щего масла, быстро прекраща его горение.When sodium bicarbonate interacts with sulfuric acid, carbon dioxide is released, which converts all the oil into a dense foam, which under pressure of the produced carbon dioxide due to the reaction and under pressure of compressed air is applied to the surface of the burning oil, quickly stopping its burning.
Примен описанную пену в качестве огнегасител гор щего масла, устран ют вление вытеснени последнего через кра хранилища, и масло остаетс не загр зненным посторонними примес ми, так как образовавшийс при этом сернокислый натрий и избыток бикарбоната натри оседают на дно.Applying the described foam as a fire-extinguishing oil extinguisher eliminates the phenomenon of the latter being expelled through the edges of the storage facility, and the oil is not contaminated by extraneous impurities, since the sodium sulphate and excess sodium bicarbonate formed during this process sink to the bottom.
