Description

Technical field

The invention relates to the field of fire fighting equipment, namely:

- to fire extinguishing gas dispersed compositions (GDS);

- fire extinguishing methods;

- modular devices for its implementation.

Using the proposed fire extinguishing gas dispersed composition, a method of extinguishing a fire using modular plants and systems based on them, this invention can be successfully used to combat fires, including for their prevention, in almost all industries: chemical, petrochemical, oil refining , woodworking, etc.

State of the art

A known fire extinguishing composition in which the mixing of homogeneous and heterogeneous inhibitors is carried out mechanically using an ejector device [USSR Author's Certificate No. 715092 of 08/11/1978].

The disadvantages are the inability to use the resulting fire extinguishing composition for volumetric fire extinguishing and its short duration of storage. The combination of homogeneous (chladone) and heterogeneous (powder) inhibitors using an ejector is recommended only for manual fire extinguishing, while it cannot be used at low temperatures down to -60 ° C.

The invention [RF Patent No. 2225735 of 04/10/2001] provides for the creation of one freon solution (for example, a compound such as perfluorocyclobutane C ₄ F ₈ , perfluorobutane C ₄ F ₁₀ , heptafluoropropane C ₃ F ₇ H, dibromotetrafluoroethane C ₂ F ₄ Br ₂ ) and potassium iodide. To do this, it is proposed to first obtain a saturated solution of potassium iodide in ethanol, after which this solution is mixed with liquid freon at a weight ratio of 70-80 wt.% Freon and 20-30 wt.% Saturated solution of potassium iodide in ethanol. The content of potassium iodide in ethanol in this case is up to 5 wt.%.

The disadvantages of the composition are the high cost of protection 1 m ³ due to the costly freons included in the formulation, and the impossibility of its use at t up to -60 ° C.

Known combined fire extinguishing composition [RF Patent No. 2156630 dated 02/08/1999], which contains a diluent - fluorine-containing saturated hydrocarbon - and a flame retardant - iodine-containing saturated hydrocarbon - in the ratio of components, wt.%: Fluorinated hydrocarbons 70-95, iodine-containing hydrocarbons 5 -thirty.

In the application [RF Application No.2000114329 of 05.06.2000], a volume quenching composition is proposed comprising air-diluting fluorocarbon and flame retardant components, wherein an iodine-containing hydrocarbon with one or two iodine atoms, in which all other hydrogen atoms are substituted, is used as a flame retardant fluorine atoms. The ratio of the components in the proposed composition is the following, wt.%: Diluent - 40-98%, inhibitor - 2-60%.

Known fire extinguishing powder composition [RF Patent No. 2143297 from 12.16.1997], including, wt.%: Highly dispersed additive, mainly aerosil, 0.8-3.5; target additive for fluidity, mainly nepheline concentrate, 8.0-35.0; hydrophobizing organosilicon liquid 0.008-0.28; the main component is the rest. As the main component, the composition contains at least one compound from the series: potassium chloride, sodium chloride, ammophos, sylvinite, sulfate, alkaline or alkaline earth metal phosphate, sodium bicarbonate, monoammonium phosphate, diammonium phosphate, ammonium sulfate.

There is also known a method of extinguishing a fire in a tank and a device for its implementation [RF Patent No. 2258549 dated 03.02.2004], according to which a fire extinguishing mixture is supplied from a device floating in the center of the tank, wherein a gas-dispersed fire extinguishing mixture is formed in the above device by applying at least 1 pressure MPa of a gaseous and / or liquefied phlegmatizer and / or gaseous and / or liquefied homogeneous combustion inhibitor in a container with a powder or liquid heterogeneous combustion inhibitor having a bursting membrane or a valve, providing, when the pressure exceeds 1 MPa, the release of the gas-dispersed mixture through the outlet pipe and the circular nozzle atomizer with compact jets with a divergence angle of 5-15 ° in the plane parallel to the liquid, with a flow rate of at least 10 kg / s and an outflow velocity at the nozzle exit of at least 70 m / s, while supplying the jets is carried out with a sweep of 360 ° so that they do not intersect in the radial direction inside the tank, creating a rarefaction in the discontinuity of the extinguishing medium, which ensures suction into the rarefaction zone combustion zone from the upper fire zone, thereby forming a continuous circular fire extinguishing zone with a ratio of fire extinguishing areas formed by gas dispersed jets and combustion products of a burning liquid in the range from 1: 1 to 10: 1, and the mass ratio between the gas and dispersed phases of the fire extinguishing mixture is in ranges from 0.2: 1 to 15: 1. As gaseous and / or liquefied phlegmatizer, carbon dioxide, and / or nitrogen, and / or argon, or a mixture thereof is used. Halogenated hydrocarbons are used as a gaseous and / or liquefied homogeneous combustion inhibitor, and a fire extinguishing powder composition based on carbonates and / or chlorides and / or phosphates of an alkali and / or alkaline earth metal and / or ammonium or fog-forming is used as a heterogeneous combustion inhibitor phosphoric acid solution.

There is also known a method [US Patent No. 6988558 B2 of January 24, 2006] to extinguish a fire using gas, according to which a fire is extinguished by the eruption of at least one gaseous extinguishing agent selected from the group formed by argon, nitrogen and carbon dioxide, however, foam, powder or water is used as their carriers.

The disadvantages of these extinguishing compositions are the high cost of protection 1 m ³ due to the costly freons included in the formulation, and the impossibility of their use at t up to -60 ° C.

Also close in components and purpose is a fire extinguishing composition [RF Patent No. 2240848 of 08/07/2003].

fine additive 0.5-2.8 target additive for fluidity 4.6-25.0 hydrophobic organosilicon liquid 0.1-0.5 main component 15-70 phlegmatizer and / or combustion inhibitor rest.
