Detailed description of the invention: core engine 1, compressor 11, main chamber 13, turbine 12, main heat exchanger 14, fire plant 2, fire-fighting
Combustion chamber 21, fire-fighting heat exchanger 22, blower 23, motor 24, battery 25, protection place 3, air valve switch 4.
Specific embodiment
Below in conjunction with attached drawing, further description of the technical solution of the present invention.
As shown in Figure 1, fire-fighting gas turbine of the invention includes core engine 1 and fire plant 2, core engine 1 is by master
Gas after combustion chamber 13 is burnt enters fire plant 2, after fire plant 2 burns again to gas, forms inert gas, then
Then entering protection place 3 after supercooling.
As shown in Figure 1, core of the invention machine 1 includes compressor 11, main chamber 13, turbine 12, main heat exchanger 14, pressure
11 outlet air of mechanism of qi is divided into two-way, is all the way the branch that burns, and another way is cooling branch, and burning branch is laggard by main chamber 13
Enter turbine 12, then enters main heat exchanger 14.Cooling branch is expelled to outdoor after being directly entered main heat exchanger 14, cooling in this way
The gas of branch cools down the gas after burning.Core of the invention machine 1 or other types, fire plant 2
The gas generated using its branch that burns.
As shown in Figure 1, fire plant 2 of the invention includes fire-fighting combustion chamber 21, fire-fighting heat exchanger 22, blower 23, motor
24, fire-fighting combustion chamber 21 is discharged gas with the main heat exchanger 14 of burning branch and connect, the gas of the 21 pairs of burning branches in fire-fighting combustion chamber
Body further burns, and generates inert gas, then flows into fire-fighting heat exchanger 22, and protection place 3 is entered after cooling.Motor 24 drives
23 turn of blower, the wind that blower 23 is blown out enter fire-fighting heat exchanger 22, and the inert gas generated to burning branch cools down.
As shown in Fig. 2, the present invention can also increase battery 25.Battery 25 is powered for monitoring device.The present invention
Battery 25 by the temperature difference charging on fire-fighting heat exchanger 22, battery 25 is powered driving to motor 24, makes work in this way
During work, battery being capable of long-term stable operation.
In the present invention, the fuel of fire-fighting combustion chamber 21 can with combustion gas or oil, by with the oxygen combustion in air, obtain oxygen
Gas concentration is less than or equal to 11% inert gas, and flame will be put out naturally when oxygen concentration content is lower than 11% in general air
It goes out.Noble gas component of the invention is mainly nitrogen, carbon dioxide and water, is inert gas that can not be combustion-supporting, and its is dense
Degree has certain positive pressure more preferably greater than 89%, therefore can not only supplant the air that normal oxygen concentration content is 21%,
But also it can prevent that thermal convection makes ignition point that can not attract fresh air that the intensity of a fire is further increased.
Blower 23 of the invention or other blowing devices, such as air blower or ventilation blower, as long as being capable of providing stabilization
Air-flow.
As shown in figure 3, air valve switch 4 can also be arranged in the present invention, air valve switch 4 is arranged in core engine 1 and fire plant 2
Between, air valve switch 4 can preferably be controlled electronically.In this way, core engine 1 can work normally when not having fire, discharge gas warp
The discharge of air valve switch 4 is crossed, when a fire, air valve switch 4 is converted, and the gas being discharged after making core engine 1 burn enters fire-fighting
Device 2 enters protection place 3 after burning by fire plant 2.
As shown in figure 4, core engine 1 of the present invention can be not provided with main heat exchanger 14,12 output gas of turbine is opened by air valve
Fire plant 2 is expelled directly out or entered after closing 4.
The present invention burning after generate a large amount of inert gas, can particular surroundings carry out using.Such as high voltage substation, nothing
People's work station on duty etc., because inert gas produced by the present invention can completely cut off the content that live oxygen is greatly lowered,
In the place that someone works or lives, it is necessary to very prudent use the solution of the present invention.
A kind of method the invention also discloses gas turbine for fire extinguishing, including following procedure, by gas turbine combustion
Gas afterwards re-starts burning, generates inert gas, protection place 3 is entered after inert gas is cooling.There is no fire
When, the gas after gas turbine combustion can normally be discharged, and when a fire, put out a fire using method of the invention.
Noble gas component is mainly nitrogen, carbon dioxide and water, is inert gas that can not be combustion-supporting, the oxygen concentration of inert gas
Less than or equal to 11%.
Apparatus and method of the present invention is particularly suitable for putting out a fire to unattended region.Such as high-tension transformer, using from
The mode of dynamic water spray is put out a fire, then be easy to cause high-voltage electricity to reveal, and bigger the condition of a disaster occurs.Or at precious article preservation, such as
Have using liquid fire extinguishing, then precious article can also damage, and result in greater loss.When fire occurs for the device of the invention, automatically
Starting, is put out a fire as early as possible by way of reducing scene of fire oxygen concentration.
