Description

Technical field

The utility model relates to techniques for fire fighting and fire and explosion prevention, namely, devices for extinguishing a fire and fire and explosion prevention with low and medium frequency foam or sprayed and dispersed water, and can be used for the rapid formation and even distribution of low and medium frequency foam or sprayed and dispersed water across area of fire of flammable liquids, solid combustible materials and bottling of liquefied petroleum and natural gases (LPG and LNG), as well as for cooling and / or fireproof explosion protection of buildings, structures, machinery, equipment, combustible and explosive materials in an automated mode of operation with remote control.

State of the art

It is known that at different stages of fires and fire and explosion hazard situations, namely at the stages of occurrence, development, intense burning, attenuation and possible resumption of a fire or emergency, it is effective to use different (low, medium or high) multiplicity, or sprayed and dispersed water, which accordingly requires the timely use of various foam generators and fire barrels, capable of generating either high, medium and low foam multiplicity or ensure the supply of atomized or dispersed water.

At the same time, well-known foam generators and fire barrels in the overwhelming majority of cases are specialized and are capable of generating only one fire extinguishing agent - either water foam of a certain magnitude or a jet of water of a certain dispersion, therefore, effective extinguishing of a fire and fire and explosion prevention requires the availability and prompt replacement of various means fire extinguishing, which significantly reduces the efficiency of fire extinguishing processes and fire and explosion prevention.

Known mobile and portable fire extinguishing means.

Known motor pump for fighting a fire, comprising a pump with a drive engine, an engine control unit and a hose line, the pressure hose of which has a spray gun and a connector for connecting the hose to the pump, characterized in that a switch is connected to the spray gun connected by a connecting line to the block engine control, while the pump is equipped with a heating unit for the pumped fluid associated with the connecting line [RU 30274 A62C 25/00 Publ. 06/27/2003].

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

A multi-purpose mobile foam-generating installation is known for generating foam, mainly at nuclear fuel cycle facilities, including a tank for water or a foaming agent solution, a pump with an electric motor, a comb for connecting medium-sized air-foam generators (foam generators), pipelines, hoses and reinforcement, additionally equipped with foam generators of low multiplicity (K <20) and high-foam (K = 200-1000), working with grids of two types (ordinary - flat or metal fabric - volume weaving), and a valve is installed on the comb, which allows you to smoothly control the flow rate of the foaming solution supplied to the high-foam generator with a flow rate of 0.5-10 l / min. In addition, the tank is equipped with a cover designed to seal it when pressure is created in it up to 6 atm. These signs provide an increase in the universality of the installation [RU 2308996 A62C 27/00, A62C 5/02 Publ. 10.27.2007].

The disadvantage of this device is the significant 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 previously developed by the applicant is known, comprising fire extinguishing means installed on a car trailer, characterized in that, as fire extinguishing means, the mobile fire module comprises at least one motor pump connected by fire hoses and water supply lines and a foaming agent a container for a foaming agent, at least one water tank, fire hoses, a stationary fire installation and at least one backpack fire 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 for automobile movement and the impossibility of its manual transfer to and from fire places in places difficult to access for vehicles.

Stationary and manual fire monitors are known that form water jets and foams of low multiplicity with a feed 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 foaming agents, which does not allow to obtain the required fire extinguishing effect, and leads to delay extinguishing time and the high cost of blowing agents used in extinguishing a fire.

It is known to use foam of medium multiplicity, which has increased fire extinguishing efficiency compared to foams of low multiplicity when extinguishing oil and oil products and generators of foam of medium multiplicity in portable and stationary versions. However, most of the well-known medium foam generators provide foam jets from 3 to 8 m, which complicates the process of their use due to the high risk of the personnel of fire departments 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 increase the productivity, economy and fire extinguishing efficiency by creating a combined jet of foam of medium and low multiplicity and increase the range of the foam jet of medium multiplicity up to 20-50 m, a solution is supplied a foaming agent on the mesh in the foam generator housing to produce a medium-sized foam jet with the formation of a foam jet with increasing frequency and decreasing ysya density from the center to the periphery. At the same time, two or more jets of a foaming agent solution from two or more nozzles or other means of forming directed jets are simultaneously fed onto the foam generator grid, with the possibility of formation of two or more adjoining and / or mutually intersecting jets of foam of medium multiplicity in the foam generator body and / or outside it with the formation of a single jet of foam of medium multiplicity of increased range [RU 2170123 А62С 5/02 Publ. 07/10/2001].

Known portable fire extinguishing device containing a foam generator with the ability to attach to a fire hose, a means of mixing water with a foaming agent in communication with a foam generator, a container with a foaming agent and a means of supplying a foaming agent to a means of mixing water with a foaming agent, characterized in that the foam generator is made in a portable version, and the tank with the foaming agent is made with the possibility of its placement and transfer in the satchel, and the means of supplying the foaming agent to the means of mixing water with the foam the driver is made in the form of a hose connecting the container located in the satchel with a foaming agent and a means of mixing water with a foaming agent [RU 117297 A62C 15/00 Publ. 06/27/2012].

The closest in technical essence and the achieved technical result (prototype) is a device previously developed by the applicant with a hydraulic oscillator to extinguish a fire and fire and explosion prevention with low and medium multiplicity foam, which, to increase compactness, mobility and simplify the operational movement of a low and medium multiplicity foam generation device, directly to the place fire, increasing the efficiency of fire fighting, range and uniformity of foam distribution over the area of the fire, increasing safety for extinguishing fires and fire and explosion prevention with foam of low and medium frequency, contains a foam generator of low and medium frequency, a base with a pressure pipe and a hydraulic oscillator with the ability to create 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 176644 is the ability to generate only combined foam of low and medium multiplicity, as well as the need to enable / disable the operator and manually control the operator by turning the foam generator in a vertical plane.

A common disadvantage of the known water-based fire extinguishing devices is that the known stationary and mobile devices require manual control and the presence of operators near the devices in the vicinity of the fire-fighting zone and are not sufficiently effective due to the generation of foam of only a certain multiplicity or water jets of a certain dispersion, which their use in various conditions and at different stages of extinguishing a fire 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 task has not been solved so far) that hinders the possibility of the effective use of known fire extinguishing means (foam generators, fire monitors and other fire extinguishing means) is the need for the constant presence of operators near the foam generators in the process of extinguishing fires and fire and explosion prevention in industrial enterprises with special explosion and fire risk industries, for example, at enterprises of the petrochemical industry or at an enterprise handling of LPG and LNG, as well as at emergency chemical hazardous facilities where the release of potent toxic substances occurs, at facilities for the storage and manufacture of explosives, as well as at facilities where it is necessary to use highly effective combined foams of low and medium multiplicity as a fire extinguishing agent .

Known fire extinguishing means are characterized by the inability to provide an automatic fire extinguishing process 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 supply of only individual jets of foam of a certain multiplicity or atomized water of a certain dispersion and only to specific, point-like fire places, which is effective in extinguishing small fires in low-rise residential and industrial buildings in urban and rural settlements .

At the same time, when extinguishing large-scale industrial, forest and - road traffic fires, a controlled, quick and uniform coating of the entire fire-hazardous area with fire extinguishing agents is required, and at various stages of extinguishing fires and fire and explosion prevention it is advisable to use various fire extinguishing agents (an aqueous solution of a foaming agent or water) in different consistencies ( in the form of foam of low and medium multiplicity or sprayed and dispersed water) with an operational change in their supply to the fire zone and fire Prevention. which, in turn, limits the efficiency and speed of extinguishing large-scale fires.

The technical result achieved by using the proposed device is

increasing the efficiency of fire fighting and fire and explosion prevention by enabling the proposed device to generate either combination foam of medium and low multiplicity, or only foam of medium multiplicity, or only foam of low multiplicity, or combined sprayed and dispersed water, or only sprayed water, or only dispersed water, and the possibility of operational coverage with fire extinguishing means of the entire area of the fire and fire and explosion prevention,

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

Utility Model Implementation

The inventive device for extinguishing fires and fire and explosion prevention, hereinafter referred to as the "device", is intended to extinguish fires and fires and explosion prevention with foam of low and medium multiplicity or sprayed and dispersed water, hereinafter referred to as "extinguishing agents", with a uniform distribution of extinguishing agents over the area of fires of class B combustible liquids , Class A solid combustible materials, as well as liquefied petroleum 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 flows of air-mechanical foam of low and medium multiplicity or sprayed and dispersed water in various combinations and automatically direct them to the fire extinguishing and fire prevention zone with the possibility of uniform distribution over the entire area of the fire 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 petroleum and natural gases (LPG and LNG).

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

In terms of resistance to the effects of climatic environmental factors, the device can be made in the design U (moderate climate) and UHL and placement category 1 according to GOST 15150-69.

Structurally, the device comprises (Fig. 1, 2) a foam generator housing 1; nozzles 2 for supplying a fire extinguishing agent in the form of an aqueous solution of a foaming agent or water to the nets 3 of the foam generator of the corresponding formation of medium-frequency foam or sprayed water; a pipeline 4 for supplying a fire extinguishing medium with means 5 for attaching it to a pressure main pipeline of a fire extinguishing medium; barrel 6 of the formation of foam of low multiplicity or dispersed water with possible openings 16 for air intake; a three-way valve 12 mounted on the fire extinguisher supply line 4 with a working body in the working position of the pipeline 4 overlap with an additional barrel 9 connected to the three-way valve; openings 16 for suction of air into the barrel 6 of the formation of foam of low multiplicity; holes 17 suction air into the additional barrel 9 formation of foam of low multiplicity ..

The proposed device can function and be used in various options for generating flows of foam of low and medium multiplicity or atomized and dispersed water (Fig. 2-4) depending on the position of the shut-off element of the three-way valve 12, and also depending on the use of an aqueous solution as a fire extinguishing agent blowing agent or water.

The device is manufactured with the possibility of remote control and the possibility of automated fire fighting and fire and explosion prevention by the flows of foam of low and medium multiplicity or sprayed and dispersed water in various combinations.

A fire extinguishing agent, in the form of an aqueous solution of a blowing agent or water, under a preferential pressure of 0.8 MPa (8 kgf / cm ² ) is supplied to the device via a pressure pipe through a connection means 5 and a pipe 4 and can be distributed by two through a three-way valve 12 and two corresponding pipelines flow.

In one stream, an aqueous solution of a foaming agent or water can be supplied to a foam generator, that is, to nozzles 2 and further to grids 3, and through another stream to an additional barrel 9.

The presence of a three-way valve 12 located on the supply line of the fire extinguisher means allows the device to be used in various operating modes with the corresponding possibility of generating the device,

when using an aqueous solution of a foaming agent or a combination foam of medium and low multiplicity, or foam of low multiplicity, as an extinguishing agent,

and when using water as a fire extinguishing agent, a combined stream of atomized and dispersed water, or a stream of dispersed water.

With the simultaneous supply of extinguishing agent to the foam generator and to the additional barrel 9 (Fig. 3, 4), the device can generate

when using as an extinguishing agent an aqueous solution of a foaming agent, a stream 13 of foam of medium and low multiplicity with an average multiplicity of 30-40 and a stream of foam of low multiplicity with a multiplicity of 5-10, or,

when using water as a fire extinguishing agent, the combined stream 15 of sprayed and dispersed water with an average dispersion of 150 microns and a stream of dispersed water with a dispersion of more than 200 microns.

In this case, the flows of low-frequency foam or dispersed water formed under the foam generator, having a higher density and correspondingly greater kinetic energy reserve compared to medium-frequency foam and atomized water, move with greater speed, are the first to touch the burning surface and, having a higher heat capacity, cool the burning surface. As a result of this, the streams of medium-sized foam or atomized water coming in afterwards are protected from thermal effects and rapid destruction and evaporation, which increases the efficiency of fire fighting and fire prevention.

At the same time, spouts of low-foam or dispersed water located at the bottom, having a higher density, higher kinetic energy and, accordingly, greater range, provide longer-range delivery (up to 60-90 m) of medium-frequency foam or atomized water compared to conventional medium-frequency foam generators or sprayed water.

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

When applying a fire extinguishing agent only in the foam generator 2 (Fig. 5, 6) it is possible to generate a device

when using as an extinguishing agent an aqueous solution of a foaming agent, a stream of combined foam of medium and low multiplicity with an average ratio of 30-40, or,

when using water as a fire extinguishing agent, a combined stream of atomized water and dispersed water with an average dispersion of 150 microns to 100 microns.

The flows of medium-sized foam and atomized water can be effectively used at the stages of fire and explosion prevention, extinguishing a fire and preventing re-ignition, which also provides effective fire extinguishing and fire and explosion prevention.

When applying a fire extinguishing agent only in the additional barrel 9 (Fig. 7, 8), it is possible to generate a device

when using as an extinguishing agent an aqueous solution of a foaming agent, a stream 15 of foam of low multiplicity with a multiplicity of 5-10, or

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

The flows of low-foam and dispersed water having a higher heat capacity can be delivered more far and used efficiently at the stages of extinguishing intense combustion and fire and explosion prevention to cool the fire zone and possible fire or excessive heating, which also provides effective fire fighting and fire and explosion prevention.

The presence of turns in the device in vertical and horizontal planes containing electric, pneumatic or hydraulic motors with the possibility of connecting them to the remote control system makes it possible to quickly evenly cover the entire area or the surface of the fire with fire extinguishing equipment or the whole fire and explosion hazardous area or surface, which also ensures effective fire extinguishing and fire prevention

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

Production of a three-way valve installed on the supply line of a fire extinguisher, as well as turns in vertical and horizontal planes with electric, pneumatic or hydraulic actuators with the possibility of their connection to a remote control system, with the possibility of controlling them using an external remote control or radio signals of a remote control system or fire alarms allows their automated functioning and remote control without the presence of op directly in the area of extinguishing fire and fire and explosion prevention, that is, it increases the safety of the process of extinguishing fires and fire and explosion prevention at fire and explosion hazardous enterprises and facilities, which is especially important for plants and storage and consumption of liquefied petroleum and natural gases (LPG and LNG).

The possibility of manufacturing a device with pneumatic or hydraulic actuators with the ability to connect them to a remote control system also increases the safety of the fire extinguishing process and fire and explosion prevention at fire and explosion hazardous enterprises and facilities where it is not allowed to use spark-generating electrical equipment, for example, in explosive production facilities and storage and processing facilities combustible gases, petroleum products, liquefied petroleum and natural gases (LPG and LNG).

The device has a compact appearance, it is convenient to carry / transport and connect to the main pipelines for supplying water or an aqueous solution of a foaming agent.

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

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

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

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