Description

V- °:,., - “,, 2. , v.s. , ,,; E 21 F 5/04 INSTALLATION OF GAS VOLUME EXTINGUISHING

A useful model of the device relates to the mining industry and can be used. For dastanudono extinguishing fires in the surface objects of mines and opencasts.

A device for supplying freon in a valve / torus for remote extinguishing of underground fires in mine workings of mines equipped with local ventilation fans, a fan housing with a main impeller mounted on an electric motor shaft, a main air duct connected to the outlet of the fan housing, and an annular spray manifold installed at the fan inlet and connected to the d / w preparation of the inhibitor (information sheet on scientific Achievement & 84-24 NTD, Kemerovo, 1984, SL-4).

The disadvantage of this device is the loss of freon in the initial section of the air duct, due to the diversion of its supply to the fan blades, which makes it impossible to increase the range of transportation of the fan with a fan stream,

A device for supplying an inhibitor to a fire is known,

made as an improvement of the known device according to М 1ё 84 24НТД in order to increase the transportation range

inhibitor due to the intensification of the process of crushing it during transportation (ed. certificate. USSR # 13b1350g; vd-E R 5/04,

1986). -

The disadvantage of this device is the complexity of the constructive

of its solution, which ensures the installation of an additional impeller, which in principle violates the explosion protection of the electric gate when solving the problem for coal mines. The installation of an additional wheel requires additional balancing research, eliminating the imbalance of the rotating parts.

Objectively, the fire protection of the surface objects of the fuel and energy complex is not sub-compliant.

The purpose of the proposed utility model is to increase the efficiency of volumetric fire extinguishing in closed facilities of the fuel and energy complex.

CpiiHOCTb of the proposed utility model, including a system of cylinders containing pressurized supply sources and tanks with freon and sprayed pneumohydraulic units with inhibitor pipelines, while the starting unit of the device with a freon unit is installed in a niche in an enclosed space, and the front pipe of the pneumohydraulic system is located in a work place made flexible enough and include interchangeable spray devices in the system (nozzles, sprinklers, sprayers and fog educators) through divorced collectors of chladone aerosols with lateral and upper direction of arrangement by various sprinklers, and the supply of an inhibitor to the protection of electrical equipment elements with their downward orientation by means of fine dispersion misting, and the distribution branches of the flexible pipeline are no less than two directions.

The proposed set of distinguishing features of the utility model has useful properties, which consists in the targeted volumetric orientation of the flows of inhibitory aerosol in closed objects with its hard-to-reach places by introducing, depending on the protected object, the redistribution of the nozzle freon charge and the sample mist.

The figure above shows the installation of gas volumetric fire extinguishing, general view.

To implement a method of protecting enclosed spaces by means of a remote start-up of the proposed utility model system in conditions of fire safety of the production processes of combustible valuable materials and equipment in cases where the fires cannot be obstructed by water, powder or airborne, inert air

the pre-installed model is installed with foam.

The installation contains a launcher block I, two blocks of engine-mounted 2, spraying devices 3 containing nozzles and foggers depending on the fire extinguishing object (in this case, the constructions1 (and foggers may require an additional inert gas cylinder as an additional launch block , not shown), two flexible distribution pipes 4, freon manifolds 5, air exhaust manifolds 6 of the pneumohydraulic system and motive system 7.

The utility model works as follows.

Extinguishing a fire in a particular building

it is carried out by filling the premises with the estimated amount of extinguishing agent, in particular type II4B2 freon (volumetric fire extinguishing). Freon consumption is determined by the formula:

where m is the flow coefficient of the nasadaa (nozzles and fog) (For the callers);

f- acceleration of gravity (, gr 9.81 m / s);

N - pressure at the nozzle of the sprinkler, m (at the farthest from the installation of the sprinkler by the end of the production of freon

N 15 m), P 3.17 kgf / cm

A - estimated cyivfMapHaH area of the model of the installation with the nozzle openings, m

The principle of operation of a volumetric gas fire extinguishing device is to displace the extinguishing (phlegmatizing) composition from the mine, the module (cylinders) through the exhaust nozzles by

compressed gas.

After actuating the installation system by

. of remotely simulated incentive CEOtemo17, by means of the starting block I, compressed gas from cylinders through the guns, the tuffs enters the modular chladone blocks 2, the gas aerosol mixture enters the chladone collectors 5, breaks daafrasha /

Swing and enter the distribution flexible pipe and ejected deliberately through nozzle nozzles (nozzles)

and fogging agents in advance of the estimated volume of the protected object, while ensuring volumetric fire extinguishing.

The proposed technical solution is useful, i: i; eJ3i to provide increased efficiency and safety, to reduce the time for .cystic impact on the fire in closed facilities.
