Description

Technical field

The invention relates to fire fighting and fire prevention equipment, namely, devices for extinguishing fire and fire explosion prevention with low and medium expansion foam or sprayed and dispersed water, and can be used for the rapid formation and uniform distribution of various combinations of low and medium expansion foam or sprayed and dispersed water on the fire area of flammable liquids, solid combustible materials and bottling of liquefied hydrocarbon and natural gases (LPG and LNG), and as for cooling and / or fire vzryvopredotvraschayuschey protection of buildings, structures, machinery, equipment, flammable or explosive materials in an automated mode with remote control operation.

The level of technology

It is known that at different stages of fires and fire and explosion hazardous situations, namely at the stages of occurrence, development, intense burning, attenuation and possible resumption of a fire or emergency, it is effective to use air-mechanical (water-air) foam of various (low, medium or high) multiplicity, or sprayed and dispersed water, which accordingly requires the timely use of various foam generators and fire rods capable of generating high, medium and low foam oh multiplicity or provide sprayed or dispersed water.

However, in the overwhelming majority of cases, well-known foam generators and fire rods are specialized and capable of generating only one fire extinguishing agent — or water foam at a certain rate or jet of water of a certain dispersity; therefore, for effective fire extinguishing and fire prevention, it is necessary to have various fire extinguishing agents, which significantly reduces the efficiency of fire extinguishing and fire prevention and prevention processes.

Known mobile and portable fire extinguishing agents.

Known motor pump for extinguishing a fire, containing a pump with a drive engine, an engine control unit and a hose line, the pressure hose of which has a barrel-sprayer and a connector for connecting the hose to the pump, characterized in that a switch is connected to the barrel-sprayer connected by a connecting line with the unit engine control, while the pump is equipped with a heating unit pumped liquid associated with the connecting line [EN 30274 A62C 25/00 Publ. 27.06.2003].

The disadvantage of this device is the low efficiency of fire extinguishing associated with a limited amount of stored extinguishing agent and with limiting the consumption of extinguishing agent.

A well-known mobile foam generating plant for multipurpose use for foam generation, mainly at the nuclear fuel cycle facilities, includes a tank for water or a foaming agent solution, a pump with an electric motor, a comb for connecting air-foam generators (foam generators) of average multiplicity and fire rods, pipelines, hoses and reinforcement, additionally equipped with low expansion foam generators (K <20) and high expansion foam (K = 200-1000), working with two types of grids (usual - flat or metal tissue - volumetric weaving), and on the comb a valve is installed, which allows you to smoothly control the flow of the foaming solution supplied to the generator of high fold foam with a flow rate of 0.5-10 l / min. In addition, the tank is equipped with a lid, designed to seal it when creating a pressure in it up to 6 atm. These signs provide increased installation flexibility [RU 2308996 A62C 27/00, A62C 5/02 Publ. October 27, 2007].

The disadvantage of this device is the considerable weight and dimensions, as well as the impossibility of its use in industrial and low-rise buildings of urban and rural settlements, forest and landscape fires.

A mobile fire module developed earlier by the applicant is known, which contains fire extinguishing agents installed on an automobile trailer, characterized in that as a fire extinguishing means the mobile fire module contains at least one motor pump connected to by fire hoses and water supply lines and a frother. a frother tank, at least one water tank, fire hoses, a stationary fire installation and at least one fire fighting device extinguishing [RU 121167 A62C 25/00 Publ. 10/20/2012].

The disadvantage of a mobile fire module according to RU 121167 is the possibility of its use only in places accessible to automobile movement and the impossibility of manually transferring it to and from places of fire in places difficult to access for equipment.

Known stationary and handheld gun trunks, forming a jet of water and low-expansion foam with a range of 20-60 m. However, they do not allow for a large area of uniform coverage, require the use of expensive film-forming fluorinated blowing agents, which does not allow to obtain the required fire extinguishing effect, leads to tightening extinguishing time and high cost of blowing agents used to extinguish a fire.

It is known the use of medium expansion foam, which has increased fire extinguishing efficiency when extinguishing oil and petroleum products and medium expansion foam generators in a portable and stationary version compared with low expansion foam. However, most of the known foam generators of medium multiplicity provide foam jets from 3 to 8 m, which complicates the process of their use due to the high risk of fire department personnel working in the fire zone.

Known previously developed by the applicant device for forming a foam jet of medium multiplicity of increased range, in which to improve performance, efficiency and increase firefighting efficiency by creating a combined foam jet of medium and low multiplicity and increasing the range of a foam jet of medium multiplicity up to 20-50 m, serves solution foaming agent on the grid in the foam generator case with the production of a jet of medium-expansion foam with the formation of a jet of foam with increasing multiplicity and reducing density from the center to the periphery. At the same time, two or more jets of foaming agent solution from two or more nozzles or other means of forming directed jets are simultaneously fed to the foamer grid with the possibility of formation in the foam generator case and / or outside of it two or more contiguous and / or mutually intersecting jets of medium-sized foam with the formation of a single jet of medium expansion ratio of increased long range [RU 2170123 А62С 5/02 Publ. July 10, 2001].

A portable fire extinguishing device is known that contains a foam generator that can be connected to a fire hose, communicating with a foam generator means for mixing water with a frother, a container with a frother and means for feeding a frother in a means for mixing water with a frother, characterized in that the foam generator is made in a portable design, and the frother is made with the possibility of its placement and transfer in the knapsack, and the means for supplying the frother to the water mixing means with frother The device is made in the form of a hose connecting a container with a frother located in the knapsack and a means of mixing water with the frother [RU 117297 A62C 15/00 Publ. 27.06.2012].

The closest in technical essence and the achieved technical result (prototype) is a device developed earlier by the applicant with a hydro-oscillator for extinguishing a fire and fire and explosion prevention with low and medium expansion foam, which increases the compactness, mobility and simplifies the rapid movement of low and medium expansion foam directly to the site fire, increasing the efficiency of fire extinguishing, the range and uniform distribution of foam across the fire area, increasing safety when extinguishing fires and fire and explosion prevention with low and medium expansion foam, contains low and medium expansion foam generator, base with pressure pipe and hydraulic oscillator with the possibility of creating automatic oscillatory movements of the foam generator in a given sector of the horizontal plane [RU 176 644 А62С 15/00 Publ. 01/24/2018 (prototype)].

The disadvantage of the prototype RU 176 644 is the ability to generate only a combined foam of low and medium multiplicity, as well as the need for the operator to turn on / off and manually control the operator by turning the foam generator in a vertical plane.

A common disadvantage of the known water-extinguishing fire extinguishing devices is that known stationary and mobile devices require manual control and the presence of operators near the devices near the fire extinguishing zone and do not have sufficiently high efficiency due to the generation of foam only of a certain multiplicity or water jets of a certain dispersity, which their use in various conditions and at various stages of fire extinguishing and fire and explosion prevention requires the presence and regular replacement of foam tors and fire nozzles for various purposes with a substantial loss of time and the corresponding ability to continue development and aggravation of combustion and resumption pozharovryvoopasnyh situations, which ultimately reduces the overall efficiency of fire suppression and pozharovzryvopredotvrascheniya.

Task and technical result

The main technical problem (the inventive problem that has not been resolved to date) that hinders the effective use of known fire extinguishing agents (foam generators, fire monitors and other fire extinguishing agents) is the need for the constant presence of operators around foam generators in the process of extinguishing fires and fire prevention from industrial enterprises with special fire and explosion hazards productions, for example, at the enterprises of the petrochemical industry or at the enterprise handling of LPG and LNG, as well as at hazardous chemical hazardous facilities, where highly toxic substances are released, at storage and manufacturing facilities for explosives, as well as at facilities where high-performance low and medium-sized combined fire extinguishing agents are necessary .

Known fire extinguishing agents are characterized by the lack of the ability to provide an automatic process for extinguishing a fire and fire and explosion prevention and require the constant presence of people.

In addition, well-known fire extinguishing agents are specialized and ensure the formation and delivery of only individual foam jets of a specific multiplicity or sprayed water of a certain dispersion and only to certain point of the fire, which is effective when extinguishing small fires in low-rise residential and industrial buildings in urban and rural areas and only with manual control.

At the same time, when extinguishing large-scale industrial, forest and road-transport fires, remotely controlled fast and uniform coverage of the entire fire-hazardous area with fire extinguishing agents is required, and at various stages of fire extinguishing and fire and explosion prevention it is advisable to use various fire extinguishing agents (aqueous foaming agent or water) in different consistencies (in the form of low- and medium-expansion foam or sprayed and dispersed water) with a quick change of their supply to the fire zone and fire and explosion prevention. which, in turn, significantly reduces the efficiency and rate of extinguishing large-scale fires by conventional means.

The technical result achieved when using the invention by creating the proposed universal device, is

improving the effectiveness of fire extinguishing and fire prevention through the possibility of generating the proposed universal device or a combined foam and medium and low multiplicity, or only medium expansion foam, or only low expansion foam, or combined sprayed and dispersed water, or only sprayed water, or only dispersed water , and the possibility of operational coverage by means of fire extinguishing the entire area of fire and fire and explosion prevention,

as well as improving the safety of the process of extinguishing fires and fire and explosion prevention at fire and explosion hazardous enterprises and objects by providing the possibility of remote control and automatic operation of the proposed device without the presence of operators directly in the fire extinguishing zone and fire and explosion prevention.

The implementation of the invention

The inventive device for extinguishing a fire and fire and explosion prevention, hereinafter referred to as “device”, is intended for extinguishing fires and fire and explosion prevention with low and medium expansion foam or sprayed and dispersed water, hereinafter “fire extinguishing agents”, with an even distribution of fire extinguishing agents throughout the area of flammable liquids of class B , solid combustible materials of class A, as well as liquefied hydrocarbon and natural gases (LPG and LNG),

The device can also be used for cooling and / or fire protection of buildings, structures, machinery, equipment, combustible and explosive materials and products.

The device is designed to create streams of low-and medium-frequency air-mechanical foam or sprayed and dispersed water in various combinations and automated their direction to the fire extinguishing and fire and explosion prevention areas with the possibility of even distribution over the entire fire area or fire and explosion prevention.

The device can be effectively used to extinguish large-scale fires of classes A and B, as well as liquefied hydrocarbon and natural gases (LPG and LNG).

The device is operational when using all types of domestic and foreign foaming agents with a concentration of from 3 to 6% to obtain medium and low expansion foam.

According to the resistance to environmental climatic factors, the device can be made in a design version U (temperate climate) and UHL and placement category 1 according to GOST 15150-69.

Structurally, the device contains (Fig. 1, 2): case 1; nozzles 2 supply of fire extinguishing agent in the form of an aqueous solution of a foaming agent or water on the grid 3 of the corresponding formation of medium expansion foam or sprayed water; pipeline 4 for supplying extinguishing agent with means 5 of its connection to the pressure pipeline of extinguishing agent; the barrel 6 of the formation of low expansion foam or dispersed water with possible holes 16 air leaks; a means 7 for rotating the device in a vertical plane; means 8 for rotating the device in the horizontal plane; the valve 10 on the pipe supplying the extinguishing agent to the nozzles 2 of the formation of medium expansion foam or sprayed water; the valve 11 on the pipe supplying the extinguishing agent to the barrel 6 of the formation of low expansion foam or dispersed water.

The device is made with the possibility of remote control and the possibility of automated fire extinguishing and fire and explosion prevention by low and medium expansion foam streams or sprayed and dispersed water in various combinations.

The proposed device can function and be used in several ways of generating low and medium expansion foam flows or sprayed and dispersed water (Fig. 3-6) depending on the opening / closing of the fire extinguishing agent supply valve 10 in the nozzles 2 and the fire extinguishing agent supply valve 11 6, and also depending on the use of an aqueous solution of a frother or water as a fire extinguishing agent.

The fire extinguishing agent in the form of an aqueous solution of a foaming agent or water under a predominant pressure of 0.8 MPa (8 kgf / cm ² ) is supplied to the device through the connection means through the connection means 5 into two devices through the respective pipelines.

Along one stream, an aqueous solution of a foaming agent or water, with the valve 10 open, can be supplied to the nozzles 2 and further to the grids 3, and through the other stream, with the valve 11 open, into the barrel 6.

Opening / closing taps 10 and 10 allows the device to be used in three different modes of operation with the appropriate ability to generate either a device of combined foam of medium and low expansion, or medium expansion foam, or low expansion foam, which results in an increase in the effectiveness of fire extinguishing and fire prevention.

With simultaneously open valve 10 supplying extinguishing agent to the nozzle 2 and open valve 11 supplying extinguishing agent to the barrel 6, that is, simultaneously feeding the extinguishing agent to the nozzle 2 and to the barrel 6 (Fig. 3), the device can generate:

when using an aqueous solution of a frother as an extinguishing agent, a stream 13 of medium and low expansion foam 13 with an average frequency of 30-40, or

when using water as a fire extinguishing agent, a combined stream 13 of sprayed and dispersed water with an average dispersion of 150 microns.

At the same time, low-expansion or dispersed water foam flows, possessing higher density and correspondingly greater kinetic energy than medium-sized foam and sprayed water, move with greater speed, first touch the burning surface and, having a higher heat capacity, cool the burning surface. As a result of this, the flow of medium-sized foam or sprayed water coming after it is protected from thermal effects and rapid destruction and evaporation, which increases the efficiency of fire extinguishing and fire prevention.

At the same time, jets of low expansion or dispersed water, located at the bottom, possessing greater density, greater kinetic energy and, accordingly, greater range, provide a more long-term delivery of medium-size or sprayed water to 60-90 m compared to conventional generators of medium-expansion foam or sprayed water .

Thus, as a result of the combined action of low and medium expansion pens or dispersed and sprayed water, effective fire fighting and fire prevention will be provided.

When the fire extinguishing agent supply valve 10 is opened in the nozzles and the fire extinguishing agent supply valve 11 is closed in the barrel 6 (FIG. 4), i.e., when the fire extinguishing agent is supplied only to the fuel injector 2, the device can be generated

when an aqueous solution of a foaming agent is used as a fire extinguishing agent, a medium-density foam flow 14 with a multiplicity of 50-70, or,

when using water as a fire extinguishing agent, a stream 14 of sprayed water with dispersity up to 100 microns.

Medium-sized foam and sprayed water flows can be effectively used at the stages of fire and explosion prevention, fire extinguishing and prevention of re-ignition, which also ensures effective fire extinguishing and fire prevention.

When the valve 10 for supplying the extinguishing agent to the nozzles is closed and the valve 11 for extinguishing the extinguishing agent to the barrel 6 is opened, i.e. when the extinguishing agent is supplied only to the barrel 6, the device can be generated

when an aqueous solution of a foaming agent is used as a fire extinguishing agent, stream 15 low-expansion foam with a multiplicity of 7-10, or

when using water as a fire extinguishing agent, stream 15 dispersed water with a dispersity of more than 200 microns.

Fluxes of low multiplicity and dispersed water possessing higher heat capacity can be delivered more far and efficiently used at the stages of extinguishing intensive burning and fire and explosion prevention to cool the fire zone and possible fire or excessive heating, which also ensures effective fire extinguishing and fire and explosion prevention.

The manufacture of cranes 10 and 11 with the ability to control the volume of the corresponding supply of fire extinguishing agent in the nozzles 2 and in the barrel 6 also provides versatility and increases the efficiency of fire extinguishing and fire and explosion prevention.

The presence of means of turns in the device in the vertical and horizontal planes containing electric, pneumatic or hydraulic motors with the possibility of connecting them to the remote control system provides the possibility of uniform and quick coverage with fire extinguishing agents for the entire area or the fire surface or the entire fire-hazardous area or surface, which also ensures effective fire extinguishing and fire prevention.

The proposed device allows its use in the automatic remote control mode and operation.

Production of fire extinguishing media installed on pipelines in the nozzles and in the barrel of cranes, as well as means of turns in the vertical and horizontal planes with electric, pneumatic or hydraulic actuators with the possibility of their connection to the remote control system, with the possibility of their control by means of a remote control or radio signals of the system remote control or fire alarm signals allows their automated operation and remote control without the presence of tviya operators directly in the fire-fighting and pozharovzryvopredotvrascheniya, ie provides increased process safety and extinguishing fires on pozharovzryvopredotvrascheniya pozharovzryvoopasnyh enterprises and facilities.

The device has a compact look, it is convenient in carrying / transporting and connecting to the main pipelines of the water supply or aqueous solution of the foaming agent.

By bundling the device with standard quick-detachable connections to pressure pipelines, it is possible to use it in conjunction with other fire hydraulics systems and fire hoses.

The proposed device for effective fire extinguishing and fire prevention can be used in inaccessible and / or difficult to reach places for conventional fire equipment - in industrial enterprises with special fire and explosion hazard of production, for example, in petrochemical enterprises or in enterprises with LPG and LNG, as well as in emergency situations. chemical hazardous objects, where it is possible to release highly toxic substances, on the storage and manufacture of explosives, as well as on the object Where it is necessary to use an extinguishing agent foams highly combined low and medium ratio, including the combined streams; It can also be effectively used to extinguish forest and landscape fires.

The device is operational when using all types of domestic and foreign foaming agents with a concentration of from 3 to 6% to obtain medium and low expansion foam.

The device can be used both in the mode of automatic suction of atmospheric air when generating foam of medium and low multiplicity or of sprayed and dispersed water (Fig. 2), and in the mode of using a compression aqueous solution of a foaming agent or compression 2 water, that is, pre-saturated with air or some kind or with an inert gas of an aqueous frother solution or water.
