Specific embodiment
The technical solution of the utility model is further described below in conjunction with attached drawing.
As shown in Figure 1, the fire-fighting gas turbine of the utility model includes core engine 1 and fire plant 2, core engine 1 is passed through
It crosses the gas after main chamber 13 burns and enters fire plant 2, after fire plant 2 burns again to gas, form inert gas,
Then then entering protection place 3 after supercooling.
As shown in Figure 1, the core engine 1 of the utility model includes compressor 11, main chamber 13, turbine 12, main heat exchanger
14,11 outlet air of compressor is divided into two-way, is all the way the branch that burns, and another way is cooling branch, and burning branch passes through main chamber
Enter turbine 12 after 13, then enters main heat exchanger 14.Cooling branch is expelled to outdoor after being directly entered main heat exchanger 14, this
The gas of the cooling branch of sample cools down the gas after burning.The core engine 1 or other types of the utility model, disappear
2, the anti-device gases generated using its branch that burns.
As shown in Figure 1, the fire plant 2 of the utility model include fire-fighting combustion chamber 21, fire-fighting heat exchanger 22, blower 23,
Motor 24, fire-fighting combustion chamber 21 are discharged gas with the main heat exchanger 14 of burning branch and connect, 21 pairs of fire-fighting combustion chamber burning branch
Gas further burn, generate inert gas, then flow into fire-fighting heat exchanger 22, after cooling enter protection place 3.Motor 24
23 turn of blower is driven, the wind that blower 23 is blown out enters fire-fighting heat exchanger 22, and the inert gas generated to burning branch drops
Temperature.
As shown in Fig. 2, the utility model can also increase battery 25.Battery 25 is powered for monitoring device.This
The battery 25 of utility model is powered driving to motor 24 by the temperature difference charging on fire-fighting heat exchanger 22, battery 25,
Make in the course of work in this way, battery being capable of long-term stable operation.
In the utility model, the fuel of fire-fighting combustion chamber 21 can with combustion gas or oil, by with the oxygen combustion in air, obtain
Oxygen concentration be less than or equal to 11% inert gas, flame is naturally when oxygen concentration content is lower than 11% in general air
It can extinguish.The noble gas component of the utility model is mainly nitrogen, carbon dioxide and water, is indifferent gas that can not be combustion-supporting
Body, and its concentration is more preferably greater than 89%, and has certain positive pressure, therefore can not only supplant normal oxygen concentration content and be
21% air, but also can prevent that thermal convection makes ignition point that can not attract fresh air that the intensity of a fire is further increased
Greatly.
The blower 23 of the utility model or other blowing devices, such as air blower or ventilation blower, as long as being capable of providing
Stable air-flow.
As shown in figure 3, air valve switch 4 can also be arranged in the utility model, air valve switch 4 is arranged in core engine 1 and fire-fighting
Between device 2, air valve switch 4 can be preferably controlled electronically.In this way, core engine 1 can work normally when not having fire, discharge
Gas is discharged by air valve switch 4, and when a fire, air valve switch 4 is converted, after so that core engine 1 is burnt the gas that is discharged into
Enter fire plant 2, protection place 3 is entered after burning by fire plant 2.
As shown in figure 4, the utility model core engine 1 can be not provided with main heat exchanger 14,12 output gas of turbine passes through gas
Fire plant 2 is expelled directly out or entered after threshold switch 4.
The utility model burning after generate a large amount of inert gas, can particular surroundings carry out using.Such as high-voltage transforming
It stands, unattended work station etc., because inert gas produced by the utility model, which can completely cut off, is greatly lowered live oxygen
Content, so in the place that someone works or lives, it is necessary to very prudent use the embodiment of the utility model.
A kind of method the invention also discloses gas turbine for fire extinguishing, including following procedure, by gas turbine
Gas after burning re-starts burning, generates inert gas, protection place 3 is entered after inert gas is cooling.In no fire
When generation, the gas after gas turbine combustion can be normally discharged, when a fire, using the utility model method into
Row fire extinguishing.Noble gas component is mainly nitrogen, carbon dioxide and water, is inert gas that can not be combustion-supporting, inert gas
Oxygen concentration is less than or equal to 11%.
The device and method of the utility model are particularly suitable for putting out a fire to unattended region.Such as high-tension transformer, adopt
It is put out a fire with the mode of automatic water jetting, then be easy to cause high-voltage electricity to reveal, bigger the condition of a disaster occurs.Or it is saved in precious article
Place, if any liquid fire extinguishing is used, then precious article can also damage, and result in greater loss.Fire occurs for the device of the utility model
It is automatic to start when calamity, it is put out a fire as early as possible by way of reducing scene of fire oxygen concentration.
