Description

Field of technology

The invention relates to fire-fighting equipment, in particular to fire-fighting equipment and can be mainly used for extinguishing large-scale fires and carrying out emergency rescue operations in transport, when eliminating the consequences of emergency situations with fire and explosive materials and cargoes of hazard classes III-IV, when carrying out emergency rescue operations in areas of natural and man-made emergencies, fast-growing hydrocarbon fires on sea vessels and offshore platforms for hydrocarbon production and offshore coastal facilities with a high degree of fire and explosion hazard.

State of the art

Dangerous goods (fire, explosive and chemical substances) are transported mainly by rail, large-capacity road and sea transport in tanks and containers.

Fires in railway and large-capacity road and maritime transport are particularly complex.

The explosion of railway tanks with petroleum products occurs, as a rule, 16-24 minutes after the start of exposure to an open flame. The height of the flame reaches 50 meters. The explosion of one railway tank contributes to an increase in the fire area to more than 1500 m ² . The impact of open flame and high temperature on railway tanks with flammable liquids and gases leads to a flash of the oily layer on their surface. The presence of leaks and malfunctions of shut-off valves on tanks with flammable liquids and liquefied hydrocarbon gases leads to an outbreak of liquid vapor above the necks of the tanks, as well as gases above excess valves.

The most rapid spread of fire occurs when flammable liquids (FLL) and flammable liquids (FL) spill from railway and road tanks as a result of accidents, collisions or derailments of trains and cars.

Statistics of fires on railway tanks with flammable liquids and flammable liquids show that the area of liquid spill from one tank is 800-1400 ^m2 , depending on the condition and type of soil, weather conditions and terrain, as a result of which the fire area can reach 10000-35000 ^m2 .

When tanks with liquefied hydrocarbon gases (LPG) explode, a torch is emitted to a height of up to 120-150 m, followed by flame combustion up to 50 m high. Fragments of exploded tanks are scattered over a distance of up to 150 m, and in some cases up to 450 m. Sometimes an explosion tears the tank off the railway platform and throws it at a distance of up to 80 m. All this leads to the emergence of new fires and re-ignition of spilled flammable liquids.

During fires, damage to tanks and containers with toxic gases and liquids is also possible, which leads to gas contamination of the area and difficulty in combat operations until the fires are extinguished, and also necessitates the evacuation of the population from areas adjacent to the scene of the incident.

Extinguishing fires during accidents on large-capacity transport is complicated by:

high fire load and chemical hazard of transported large-tonnage cargo;

rapid spread of fire;

spills of flammable, combustible, poisonous and toxic liquids from tanks and the formation of gas-polluted areas in the adjacent territory;

the presence of a threat to nearby people;

the usual limitation of entrances and approaches to the site of an accident and fire and the complexity of laying hose lines;

absence or remoteness of water sources;

air shock wave of explosions, the resulting cloud of fuel-air mixtures of LPG and flammable liquids, the mechanical impact of fragments of tanks formed during the explosion].

A distinctive feature of accidents and disasters at sea transport and on-site facilities for the production, processing and transportation of petroleum products and liquefied natural gas is the extreme speed of development of emergency processes associated with the release of hydrocarbons and their combustion in conditions of dense placement of technological equipment.

It is for this reason that the basic concept of fire and explosion suppression systems on marine ships and platforms is the need to provide an instant response to a fire of any size.

The most important factor in localizing fire extinguishing on large-scale railway and road transport, on sea vessels and offshore platforms for hydrocarbon production and offshore coastal facilities with a high degree of fire and explosion hazard is the prevention of flaming combustion in any form. The physical essence of this condition lies in the fact that the concept of “fire extinguishing” means the creation of such physical conditions that would exclude the possibility of continuing combustion processes in any form and of any material.

Mobile and stationary container-type fire extinguishing installations are known that supply water, foam or a fine jet by pump.

Well-known marine complete pumping stations are Nijhuis Fire Fighting Protection (Netherlands), SPP-Pumps Ltd. (England), MTT (USA), Flughafenfeuerwehr Baden-Airpark (Germany), allowing to generate either only jets of water or jets of low-expansion foam of the required range, but unsatisfactory efficiency when extinguishing hydrocarbon fires due to the low efficiency of extinguishing hydrocarbon fires with water due to their greater low density compared to water. Therefore, water-foam fire extinguishing systems and methods are being intensively developed.

Low expansion foams have good cooling ability and a high rate of spreading over the surface of the fuel, and an increased supply range. However, they are not effective enough due to their low insulating ability; in addition to low expansion foam, they are usually prepared on the basis of expensive and environmentally harmful fluorine-containing foaming agents.

It is known that water-air-air-mechanical foams have good heat-insulating properties, but their use in large-scale fires is limited due to the usual short range, low spreading rate on the surface of the fuel, high coefficient of destruction from the effects of radiant thermal and convective flame flows, as well as from heated metal and other structures of a burning object.

Monitor and hand guns are known that form jets of low expansion foam with a delivery range of 20-60 m. However, they have insufficiently effective fire extinguishing properties, do not allow for a large coverage area and require the use of expensive film-forming fluorinated foaming agents, which does not allow obtaining the required fire extinguishing effect, leading to to prolongation of extinguishing time and the high cost of foaming agents consumed when extinguishing a fire.

It is known to use medium expansion foam, which has increased (compared to low expansion foams) fire extinguishing efficiency when extinguishing oil and oil products, and foam generators in portable and stationary versions. However, most previously known medium expansion foam generators provided foam jets from 3 to 8 m, which made their use difficult due to the high risk of fire department personnel working in the fire zone. Similar methods and devices for forming a jet of medium-expansion foam, described in A.S. USSR N 1789239, class. A62C 31/12, publ. 01/23/93, and a.s. CCCP N 1614813, cl. A62C 5/02, publ. 12/23/90.

A device for forming a combined jet of foam of medium and low expansion with a range of a jet of foam of medium expansion of up to 20-50 m is known, containing a means for forming a jet of a foaming agent solution, a foam generator housing and a mesh located in the housing, the foam generator housing is made in the form of a hollow cylinder, to which on the supply side foaming agent solution, a nozzle or other means of forming a jet of foaming agent solution is attached and inside of which a mesh is fixed on the foam outlet side, wherein the body of the foam generator has a length from 0.3 to 1.5 times the distance from the means of forming a jet of foaming agent solution to the mesh. In this case, the means for forming a directed jet of foaming agent solution is configured to regulate the opening angle and/or adjusting the direction of the axis of the foaming agent solution jet and/or regulating the amount of foaming agent solution, ensuring the possibility of forming a foam jet with increasing and decreasing frequency in the foam generator housing or in the space outside the generator housing density in the direction from the center of the jet to the periphery. The foam generator additionally contains a diffuser fixed in the foam generator body directly behind the mesh on the side of the foam outlet, made 0.1 - 0.9 times the diameter of the diffuser in length and having a free cross-sectional area smaller than the cross-sectional area of the mesh, and the means for forming a directed jet of the foam concentrate solution is configured to direct mixing of water and foaming agent in it, made, for example, in the form of an ejection device [RU 2170123, A62C 5/02, Publ. 07/10/2001].

The disadvantage of these fire extinguishing agents is that the fire extinguishing efficiency is insufficient for extinguishing large-scale fires and the range is insufficient.

A device for fire and explosion prevention and fire extinguishing, previously developed by the applicant, is known, manufactured with the ability to receive and supply to the fire and explosion prevention and fire zone at least one jet of hybrid foam with a multiplicity of 20 to 40, obtained as a result of turbulent mixing under a pressure of 0.6-1.4 , mainly 0.8-1.2 MPa, as a result of turbulent mixing in the process of co-movement of coaxial, touching or intersecting jets of low expansion air-mechanical foam with an expansion ratio of 5 to 15 and jets of medium expansion air-mechanical foam with an expansion ratio of 25 to 15 70 with their corresponding ratio in terms of consumption of the foaming agent solution used for their formation from 8:1 to 1:1 and their corresponding volumetric ratio from 0.1 to 1.0 [RU 2757479, A62C 3/06, A62C 5/02, publ. 10/18/2021 Bulletin. No. 29].

The advantages of hybrid foam are its increased fire-extinguishing properties, however, the known devices for its production have insufficient mobility and insufficient range, which are especially important for extinguishing large-scale fires and accidents.

A container of an autonomous fire module is known, which, in order to increase safety during rescue operations associated with extinguishing fires on floating objects, contains ventilation hatches and a telescopic tiltable lighting mast mounted on the roof with a tilt-and-turn platform, made controlled from the command compartment [RU 209417 A62C 3/10 B63C7/00 B65D88/00 Publ. 03/16/2022 Bulletin. No. 8].

The disadvantage of the autonomous fire module container according to RU 209417 is its limited application possibilities due to the presence of a protruding telescopic lighting mast in the upper part in violation of the maximum height requirements for railway transport equipment.

A fire extinguishing installation located in a standard sea container is known, intended for extinguishing fires of any power, mainly on ships, offshore platforms, oil and gas and other fire-hazardous industrial facilities through intensive supply of water or foam, including a water tank, a mechanically driven water pump, a mixer and a monitor trunk, connected by pipelines and fittings, in which the mechanical drive of the pump is made in the form of a diesel engine with a fuel tank, power supply and control panel, the mixer is connected through a pipeline with a shut-off valve to a container for foam concentrate, which is installed above the mixer, and the water tank is made in in the form of a box-shaped tank with a volume of at least 15 ^m3 . In this case, the installation is equipped with an electrical control and automation system, including a device for protecting the pump from “dry running” and starting a diesel engine, and the power source for starting the engine and operating the electrical control and automation system is made in the form of a battery. The high-performance monitor is equipped with a two-plane rotation system, the diesel engine with fuel tank, pump, power supply and control panel are mounted on a single foundation frame, all electrical and mechanical equipment of the installation is made taking into account its operation in marine conditions, power supply for starting the engine and operation of the electrical control and automation system is made in the form of an air cylinder (cylinders) and a mini-turbine with an electric generator connected to it, the water pump is connected to the ship or industrial water main, and the water tank and foam concentrate container are made of plastic [RU 2426571 A62C 35/00 Published 08/20/2011 Bulletin. No. 23].

The closest in technical essence and achieved technical result (prototype) is a system previously developed by the applicant for extinguishing fires on sea ships, offshore platforms and offshore coastal facilities, containing a pumping station with a water supply facility, a container for a foam concentrate and a pumping station connected by pipelines located in a container and connected by pipelines. fire extinguishing installations, designed with the ability to create, through a centrifugal pump and supply under the pressure of a combined water-air jet, low-expansion foam with an expansion ratio from 7 to 20 and medium-expansion foam with an expansion ratio from 20 to 100. The system is made in a mobile design with the ability to be placed in standard class containers ISO installed and used on the decks of sea vessels, offshore platforms and on vehicles of offshore coastal facilities. To create and supply, under the pressure of a combined water-air jet, low-expansion foam with an expansion ratio from 7 to 20 and medium-expansion foam with an expansion ratio from 20 to 100, “Purga” combined fire extinguishing installations located inside the container are used. The means for supplying water to the pumping station is made in the form of a water container placed in a container or near the container, or is made in the form of a water supply pipeline connected to the pumping station from behind the side of a sea vessel or offshore platform, or is made in the form of a water supply pipeline connected to the pumping station from water supply system of a sea vessel, offshore platform or offshore coastal facility [RU 108981 A62C31/12 Publ. 10.10.2011 Bulletin. No. 28 (prototype)].

Common technical disadvantages of known analogues and prototypes are limited functionality, a relatively small range and power of the foam jet, as well as insignificant water reserves, which limit the ability to extinguish large-scale fires.

The problem to be solved and the technical result achieved by implementing the invention is to increase the efficiency of explosion and fire prevention, fire extinguishing and liquidation of accidents of man-made and natural nature during the prompt stopping and extinguishing of large-scale fires and accidents on roads and railways and at sea, as well as at stationary objects remote from roads , during rescue operations and liquidation of the consequences of emergency situations at various facilities, enterprises and organizations not related to large-tonnage transport and large-scale transportation of fire and explosive goods and materials, but within the tactical and technical capabilities of fire-fighting equipment.

Engine power of diesel pump unit 315 kW (428 hp) Fuel reserve for 3 hours of work Centrifugal pump performance 200 l/s (720 m3/hour) Pressure 120 m Discharge pipe diameter 200 mm Suction pipe diameter 250 mm Foaming agent capacity 10 m ³ Sleeves with a diameter of 51 mm 800 m Sleeves with a diameter of 66 mm 800 m Sleeves with a diameter of 77 mm 400 m Outdoor floodlights 2x1000 W Weight with equipment (without foaming agent) about 15,000 kg Overall dimensions (LxWxH) 12,192x2,438x2,591 m

The autonomous fire module according to the invention functions as follows:

Using appropriate hoses, the pipeline system is connected to a tank or other third-party water sources, from where water is supplied through intake pipelines and a suction pipeline to the pump.

By means of a starter, the engine of the diesel pump unit shown in the drawings is started from its own battery, or (not shown in the drawings) the electric motor of the pump is turned on by means of an electric generator.

The pump supplies water under pressure into pressure pipelines with shut-off and control valves and pressure control gauges and, passing through foam mixers, it is supplied under pressure to water-foam fire extinguishing devices and into pressure pipelines with connections for fire hoses and manual fire extinguishing equipment.

The inclusion of foam mixers is carried out using the appropriate taps, when opened, the foaming agent from the foaming agent tanks is sucked into the pressure pipeline by ejection to obtain an aqueous solution of the foaming agent of the required concentration.

Then water or an aqueous solution of a foaming agent is directed through separate pressure pipelines to water-foam fire extinguishing devices located on the roof of the container and/or through attached fire hoses to manual fire extinguishing equipment.

The operation of individual components of equipment is carried out in the usual manner in accordance with the operating instructions for the relevant equipment and systems by specially trained personnel.

Devices, equipment, remote control systems, video surveillance, power supply and lighting systems that are known and used in firefighting equipment can be used as separate mechanisms, components and systems in an autonomous fire module.

A characteristic feature of the invention is the possibility of simultaneous generation and delivery under pressure of several multidirectional or co-directed (unidirectional) jets of combined air-mechanical hybrid foam, allowing to effectively extinguish various types of fires and flammable materials from a distance of up to 140 m for the rapid suppression and extinguishing of large fires and accidents on railways along the route and in tunnels, as well as at stationary facilities remote from railways and highways, carrying out emergency rescue operations and eliminating the consequences of emergencies and emergencies of a natural and man-made nature at various facilities located within the tactical technical capabilities of fire fighting equipment.

In addition, through fire hoses and the corresponding pipelines and pipes for their connection, various additional fire extinguishing equipment in the form of manual, mobile and mobile fire extinguishing equipment and auxiliary and manual firefighting equipment can be connected and used in the process of extinguishing a fire.

It is known that foam is the most effective and widely used fire extinguishing agent, which is a dispersed system consisting of cells - air (gas) bubbles, separated by films of liquid containing a foaming agent [GOST R 50588-2012. Foaming agents for extinguishing fires. General technical requirements and test methods].

The ratio of the volumes of the gas and liquid phases (per unit volume) of the foam determines the structure and its properties. If the volume of the gas phase _Vg exceeds the liquid volume _Vg by no more than 10-20 times (low expansion foam), the foam cells filled with gas have a spherical shape. In such foams, gas bubbles are surrounded by liquid shells of relatively large thickness. Spherical foams are characterized by a high liquid content and, therefore, low stability. Therefore, they are classified as metastable (conditionally stable).

In unstable foams, the so-called Plateau effect is observed: the liquid phase is removed from the partitions, flowing out under the influence of gravity, and rapid coalescence occurs (from the Latin coalesce - merging, uniting) - the merging of touching gas bubbles. In foam, a gas bubble cannot move freely in either a vertical or horizontal plane. It is as if “sandwiched” by other bubbles adjacent to it.

With an increase in the V _g /V _l ratio, the thickness of the liquid film separating the gas volumes decreases, and the gas cavity loses its spherical shape. Medium expansion foams, in which the V _g / V _l ratio is several tens or even hundreds, have a multifaceted shape. Moreover, the shape of polyhedra can be different - triangular prisms, tetrahedrons, irregularly shaped parallelepipeds. During the aging process of the foam, the spherical shape of the cells becomes multifaceted. Multifaceted foams are characterized by a low liquid phase content and are characterized by high stability. In such foams, individual bubbles are brought together and separated by thin “stretched elastic films.” These films, due to their elasticity and a number of other factors, prevent the coalescence of gas bubbles. As the separating films become thinner, the bubbles come closer together, adjacent to each other and acquire a clear polyhedral shape [Bobkov S.A., Baburin A.V., Komrakov P.V. Physico-chemical foundations of the development and extinguishing of fires: textbook. manual / M.: Academy of the State Fire Service of the Ministry of Emergency Situations of Russia, 2014. - 210 pp.].

The main physical and chemical properties of the foam are:

multiplicity - the ratio of the volume of foam to the volume of the foaming agent solution contained in the foam;

dispersion - the degree of grinding of bubbles (size of bubbles);

viscosity - the ability of foam to spread over a surface;

durability - the ability of foam to resist the process of destruction [ibid.].

Depending on the expansion ratio (K), foams are divided into four groups:

foam emulsions, K < 3;

low expansion foams, 3 < K < 20;

medium expansion foam, 20 < K < 200;

high expansion foam, K > 200 [ Sharovarnikov A.F., Sharovarnikov S.A. Foaming agents and fire extinguishing foams. Composition, properties, application. M.: Pozhnauka, 2005. - 335 p.].

The dispersion of the foam is inversely proportional to the average diameter of the bubbles.

It is known that the higher the dispersion, the higher the foam resistance and fire extinguishing efficiency. The degree of foam dispersion largely depends on the conditions for its production, including the characteristics of the equipment. The expansion ratio and dispersion of the foam determine the insulating ability of the foam and its fluidity. [Bobkov S.A., Baburin A.V., Komrakov P.V. Physico-chemical foundations of the development and extinguishing of fires: textbook. manual / M.: Academy of the State Fire Service of the Ministry of Emergency Situations of Russia, 2014. - 210 pp.].

The fire extinguishing properties of foam are:

insulating effect - preventing the entry of flammable vapors, gases or air into the combustion zone, causing the cessation of combustion;

cooling effect - due to the presence of a significant amount of liquid in predominantly low expansion foam.

The cooling effect of foam is due to the water released from the foam.

The insulating effect is due to the formation of a foam layer that prevents oxygen from reaching the fire zone, including:

separation effect, which consists in isolating the liquid from the vapor phase;

the displacement effect causing the isolation of the flammable substance from the air;

blocking effect in which foam prevents the evaporation of a flammable liquid.

Low expansion foams (3 < K < 20) due to the significantly larger amount of water in the interbubble partitions (in the Plateau-Gibbs channels), they predominantly exhibit a cooling fire extinguishing effect, which is caused by the cooling effect of the foam itself and the water released from the foam.

Medium expansion foam (20 < K < 200) due to the insignificant amount of water in the interbubble partitions (in the Plateau-Gibbs channels), they predominantly exhibit an insulating fire extinguishing effect, which is caused by the creation of an atmosphere depleted in oxygen and saturated with water vapor above the combustion zone, which helps slow down and completely stop the combustion.

At the same time, due to the larger amount of water present in low-expansion foam and, accordingly, the greater density (weight per unit volume), low-expansion foam compared to medium-expansion foams can be supplied from longer distances, which significantly affects the safety of fire personnel during large-scale and explosive accidents with liquefied gases.

A characteristic distinctive feature of the proposed technical solutions is the production and use of combined hybrid water-air foam based on synthetic hydrocarbon foaming agents with a multiplicity of 20 to 40.

The authors in the applicant’s laboratory experimentally established and theoretically substantiated that combined hybrid water-air foam with a multiplicity of 20 to 40, obtained on specially modernized equipment, differs significantly in its structure, viscosity, dispersity, rheological, thixotropic and other properties significant for explosion prevention and fire extinguishing from the known ones properties of low and medium expansion foams based on hydrocarbon and fluorine-containing foaming agents.

It was revealed that as a result of turbulent shockless mixing of low-expansion foam bubbles and medium-expansion foam bubbles in the hybrid foam, average-sized foam bubbles are formed, larger in comparison with low-expansion foam bubbles, but with thicker water-containing Plato channels compared to medium-expansion foams -Gibbs.

As experimentally established by the authors, the structure of a hybrid foam with a multiplicity of 20 to 40 with water-air bubbles unique in its structure and fire-extinguishing properties allows not only to better contain the high temperature of the flame without significant destruction of the volume of the hybrid foam itself, that is, to more effectively isolate the surface of the fire, but also Deliver hybrid foam jets over significantly longer distances compared to medium expansion foam jets or combined low expansion and medium expansion foam jets.

The authors also experimentally established that when a combined hybrid foam with a multiplicity of 20 to 40 is exposed to the surface of a liquefied natural or hydrocarbon gas spill, a synergistic effect is manifested due to the simultaneous influence of several factors - cooling, dilution of atmospheric water vapor in the zone of evaporation and combustion of gas, thermal insulation and a sharp decrease in the concentration of gas and vapor of flammable liquids above the foam layer in the combustion zone, down to a decrease in the rate of the chemical reaction and a subsequent decrease in the flame temperature to the extinction temperature.

This is due to the average dispersion and thickening of the water-containing Gibbs-Plateau channels of the hybrid foam compared to low- and medium-expansion foams or compared to foam in combined low- and medium-expansion foam jets.

Full-scale fire tests of the modernized devices developed by the applicant for producing a combined hybrid foam produced by the applicant, modernized barrels and foam generators used in the proposed autonomous fire module, showed high efficiency in fire and explosion prevention and fire suppression of both flammable and combustible liquids and spills of liquefied natural and hydrocarbon gases.

The applicant carried out full-scale fire tests at the test site, where, using the modernized “Purga” combined fire extinguishing installations developed by the applicant, effective extinguishing of a hydrocarbon fuel layer over an area of 1250 m ² was ensured.

As the test results have shown, the modernized PURGA installations developed by the applicant for extinguishing fires provide a soft and smooth supply of hybrid foam to the surface of the fuel at increased distances of up to 140 meters without a rough impact on the combustion area. that is, without mixing the top layer of fuel with the foam layer.

The multiplicity of hybrid foam obtained using the modernized PURGA installations developed by the applicant ranged from 20 to 40 or 30 ± 10.

A synthetic hydrocarbon environmentally friendly foaming agent of the PO-6TS type, produced in Russia, was used. The supply range of the resulting combined hybrid foam was up to 140 m.

Full-scale fire tests of the modernized "Purga" installations developed by the applicant showed that the combined hybrid foam has a significantly softer effect on the combustion surface and greater fire extinguishing efficiency compared to foams from equipment that separately supplies low and medium expansion foams or compared to combined low and medium expansion foams multiplicity.

Authoritative specialists from international organizations present at the tests came to the conclusion that the equipment for “hybrid foam” produced by the applicant LLC NPO SOPOT can become an effective option for the use of foam concentrates and foams that do not contain fluorine.

The devices used by the applicant for extinguishing large-scale fires and fire-explosion prevention with combined water-air hybrid foam with a multiplicity of 20 to 40 showed the possibility of effectively extinguishing fires with uniform distribution of hybrid foam over the area of fires of flammable liquids of class B, solid combustible materials of class A, as well as liquefied hydrocarbon and natural gases (LPG and LNG).

The devices developed by the applicant can also be used for cooling and/or fire protection of buildings, structures, machinery, equipment, flammable and explosive materials and products, as well as fire and explosion prevention at the scene of accidents with fire and explosive materials.

The fire extinguishing devices used, developed by the applicant, provide the creation of jets of combined water-air foam of hybrid foam with a multiplicity of 20 to 40 with the ability to automatically direct them to the fire extinguishing and explosion prevention zone and with the ability to remotely control the on/off of foam generators and rotation of foam generators in the vertical and horizontal plane, which allows They can be effectively used for extinguishing large-scale fires of classes A and B with combined foam, as well as liquefied hydrocarbon and natural gases (LPG and LNG), and they are efficient when using all types of domestic and foreign foam concentrates with a concentration of 3 to 6% to obtain low and low foam. medium frequency

The devices used, developed by the applicant, have a compact design, are easy to transport and connect to the main pipelines for supplying water or an aqueous solution of a foaming agent; due to the configuration with standard quick-release connections with pressure pipelines, it is possible to use it in conjunction with other fire hydraulic systems and fire hoses.

These water-foam fire extinguishing devices using jets of combined air-mechanical hybrid foam with a multiplicity of 20 to 40 can be quickly moved or transported to the required location, quickly assembled and prepared for use in places inaccessible and/or difficult to reach for conventional fire fighting equipment - in industrial enterprises with special explosion and fire hazard in production facilities, for example, at petrochemical industry enterprises or at enterprises handling LPG and LNG, as well as at emergency chemical hazardous facilities where the release of highly toxic substances is possible, at storage and production facilities for explosives, as well as at facilities where it is necessary the use of highly effective low and medium expansion foams, including combined jets, as a fire extinguishing agent; and can also be effectively used to extinguish various large-scale fires, including fires of liquefied hydrocarbon and natural gases (LPG and LNG)

The main idea of ensuring safety in case of accidents with liquefied flammable gas (LPG and LNG) comes down to the rapid, almost instantaneous taking under physical control of the entire free surface of the flowing or spreading fire-explosive liquid of liquefied flammable gas from the moment the process of outflow or spreading begins, with the desirable use of automatic switching systems and managing the process of stopping and eliminating an accident with liquefied flammable gas by accelerating the formation on the surface of a liquefied gas spill of a layer of combined hybrid water-air foam with a multiplicity of 20 to 40, mainly based on a synthetic hydrocarbon foaming agent.

As a technical technique, a technical way to implement this idea of neutralizing or stopping the dangerous factors of accidents of this kind, the idea was accepted (and corresponding technical methods were proposed) of promptly covering the entire free surface of a spill of flammable liquids and liquefied flammable gas (LPG and LNG) with a combined hybrid water-air foam with an expansion ratio from 20 to 40 mainly based on a synthetic hydrocarbon foaming agent of a certain expansion rate, with certain parameters and properties, using certain technical devices, systems and devices.

The parameters, composition and properties of combined hybrid water-air foam with a multiplicity of 20 to 40, mainly based on a synthetic hydrocarbon foaming agent, as well as modes and methods of its supply, have been determined and justified experimentally, taking into account the thermodynamic and thermophysical features of its interaction during its direct contact with the surface of a liquefied liquid spill. combustible gas (LPG and LNG).

The specificity of the problem solved by the invention is that for all other options for the use of air-mechanical and even chemical foams for the purpose of extinguishing fires of flammable liquids (FLL) and flammable liquids (FL) and/or even protecting them from ignition, a very significant role, and When extinguishing fires of flammable liquids (FL), even the dominant role is played by the process of cooling the surface of a burning liquid from its boiling point, to which its surface warms up in the first 3-5 minutes of the fire, to a lower temperature (for the option of extinguishing a fire of flammable liquids (FL) ), generally to a temperature below the flash point.

When extinguishing a fire with flammable liquids (flammable liquids), the temperature of the surface layer of the liquid is reduced to a temperature below its boiling point.

At the same time, in all cases the intensity of evaporation of flammable liquids and gases decreases, the elastic vapor pressure of the burning liquid under the foam layer and their partial pressure decreases. Then the mechanical insulating effect of the foam layer only completes the process of isolating the burning liquid and its vapors from the combustion zone, from the fire flame zone, and the combustion of flammable liquids and gases stops. This is how the process of extinguishing fires of flammable liquids and gases occurs.

The thermophysical picture of the thermal interaction of contacting media when applying air-mechanical foams to the surface of the SG looks significantly different.

The temperature of air-mechanical foam rarely goes beyond +1 to +15°C. This means that the heat difference (thermal pressure) from foam to LPG is about 30-40°C, and for LNG even 150-160°C. Therefore, the process of evaporation of liquefied fuel gas (LPG and LNG), due to the heat flow from the foam, when applied, is not reduced, but, on the contrary, intensified.

Thus, the process of preventing fire (stopping) the process of passage of flammable gas vapors into the above-foam space, into the zone of possible combustion, comes down to the processes of sorption, absorption, retention of the flow of liquefied combustible gas vapors, which, according to the invention, can be provided by a foam layer of a certain composition, a certain thickness and a certain structure.

Due to the fact that the process of destruction of liquid foam, even in the absence of a fire above or below it, proceeds continuously, and part of the foaming agent flows down through the foam and falls on the surface layer of liquefied combustible gas (LPG and LNG), the process of intensifying their evaporation, for The swelling of the “warm” foam solution continues continuously, but can be limited by the ice layer of frozen foam located directly on the surface of the liquefied flammable gas spill; the ice layer of frozen combined water-air foam of low and medium expansion and hybrid foam.

It has been experimentally determined and theoretically substantiated that a special role in the situation of a spill of liquefied flammable gas (LPG and LNG) is played by phase transformations at the interface between the foam/LPG and/or foam/LNG phases (foam/liquefied flammable gas) and the surface layer of liquid substances of liquefied fuel gas

When the liquid phase of the foam comes into contact with the liquid phase of fuel having a temperature of -162°C (with LNG) or -42°C (with LPG), the lower layers of the foam freeze, turning into the solid phase of a certain snow-like structure. Under the layer of frozen snow-like foam, a porous ice substrate begins to form directly on the surface of the liquefied flammable gas spill.

Depending on the dispersion and expansion ratio of the foams used, the physical and chemical nature of the foaming agent solution and the ratio of surface tension forces at the interface, the density, porosity, gas permeability, thermal conductivity and buoyancy of the resulting snow-like layer of frozen foam under the protective layer of liquid foam depend.

Consequently, the heat-insulating and gas-insulating properties of the layered “sandwich” on the surface of a liquefied flammable gas spill depend most significantly on this: vapors of liquefied flammable gas, an ice layer, a layer of frozen gas-saturated foam and a layer of liquid gas-saturated foam or a layer of frozen gas-saturated foam and a layer of liquid gas-saturated foam .

Further parameters of the process of evaporation of the flammable substance of liquefied flammable gas and the penetration of its vapors into the zone of possible controlled combustion above a layer of gas-saturated foam or controlled combustion of gas-saturated foam (the concentration of flammable gas vapors above the foam or the concentration of gas in the foam) depend on the thermophysical properties of the ice layer of frozen foam and the next layer of liquid foam. From their thickness, gas permeability, thermal conductivity, sorption properties of the layer of frozen gas-saturated hybrid foam and the layer of liquid gas-saturated hybrid foam located above.

The authors' research and full-scale fire tests have shown that expensive imported fluorine-containing film-forming foaming agents are the worst known foaming agents for stopping and extinguishing LPG and LNG fires, and the most effective are cheap, environmentally friendly synthetic hydrocarbon foaming agents produced in Russia, for example, synthetic hydrocarbon foaming agents of the PO- type. 6CT.

It has also been established experimentally that it is advisable to use the developed modernized PURGA installations produced by the applicant as generators of combined hybrid foam for stopping and extinguishing LPG and LNG fires and recycling LPG and LNG spills, which ensure the formation and supply of combined hybrid foam at a distance of up to 140 meters.

Thus, water-foam fire extinguishing devices used in an autonomous container-type fire module with the ability to form and supply jets of combined hybrid air-mechanical foam under pressure provide a significant increase in the fire extinguishing efficiency of various large-scale fires.

Therefore, all general and specific features reflected in the claims are essential and are in a cause-and-effect relationship with the technical result obtained from the use of the invention.

The possibilities of eliminating emergency spills, fire and explosion prevention, stopping and extinguishing fires of spills of flammable liquids (FLL) and flammable liquids (FL), as well as liquefied natural gas or liquefied hydrocarbon gas with combined water-air hybrid foam with an expansion ratio of 20 to 40, have been determined experimentally and practically verified in the process full-scale fire tests.

Full-scale tests in the field showed a confident solution to the actual problem and achievement of the required technical result, namely, the implementation of the present invention makes it possible to increase the efficiency of fire and explosion prevention and extinguishing large-scale emergency transport and industrial accident fires by increasing the range, uniformity and softer distribution of combined water-air hybrid foam by fire area, increasing the safety of the process of fire extinguishing and fire and explosion prevention at particularly fire and explosion hazardous facilities and in the elimination of technological and transport accidents by preventing fires, explosions, reducing the intensity of combustion and extinguishing fires in the energy, transport, gas production, gas processing and chemical industries, as well as the possibility of extinguishing individual fires using manual and mobile fire extinguishing equipment and fire hoses with low and medium expansion water-air foam and hybrid foam from a distance of up to 800 m.
