Description
Technical field
The present invention relates to fire extinguishing field, spy is related to a kind of continuous inert gas generator of fire extinguishing.
Background technique
Existing office space is generally put out a fire by the way of water spray, is suitable for most of occasions and is used.But it is right
In certain Code in Hazardous Special Locations, the mode for being not particularly suited for water spray is put out a fire, as high voltage substation, valuables save place or nothing
People mountain area on duty needs while fire extinguishing for these regions, keeps the safety of live article as far as possible.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of continuous inert gas generators of fire extinguishing.The present invention couple
After the inert gas that burning branch branch generates carries out cooling, then inert gas is sent into and protects place, reduces protection place oxygen
Gas content, to realize the goal of the invention of fire extinguishing.
The technical scheme is that a kind of continuous inert gas generator of fire extinguishing, including blowing device, combustion chamber,
Motor, heat exchanger, motor is for driving blowing device to rotate, it is characterised in that: blowing device outlet air is divided into two-way, is all the way combustion
Branch is burnt, another way is cooling branch；Burning branch generates inert gas behind combustion chamber, and inert gas enters heat exchanger,
Subsequently into protection place；Cooling branch is discharged after entering heat exchanger.
According to the continuous inert gas generator of a kind of fire extinguishing as described above, it is characterised in that: blowing device be blower,
Air blower or ventilation blower
According to the continuous inert gas generator of a kind of fire extinguishing as described above, it is characterised in that: the fuel of combustion chamber is
Combustion gas or oil, by with the oxygen combustion in air, obtain inert gas of the oxygen concentration less than 11%.
According to a kind of continuous inert gas generator of fire extinguishing as described above, it is characterised in that: further include battery, store
Battery is charged by the temperature difference on heat exchanger, and battery is powered motor.
According to a kind of continuous inert gas generator of fire extinguishing as described above, it is characterised in that: inert gas concentration model
Enclose is 8%, 9% or 10%.
The beneficial effects of the present invention are: first is that being put out a fire by way of reducing scene of fire oxygen concentration, it is ensured that live object
Product will not damage.Second is that protection place can be arranged in for a long time, occur to start automatically when fire.Third is that structure is simple, investment is small,
Economical operation.Fourth is that the device of the invention analogizes to the CO2 fire extinguisher of big reserves, 100kg or more CO2 fire extinguisher can be reached
Fire-suppressant gas.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of another embodiment of the present invention.
Detailed description of the invention: blower 1, combustion chamber 2, motor 3, heat exchanger 4, protection place 5, battery 6.
Specific embodiment
As depicted in figs. 1 and 2, the continuous inert gas generator of fire extinguishing of the invention includes blower 1, combustion chamber 2, motor
3, heat exchanger 4, for motor 3 for driving blower 1 to rotate, 1 outlet air of blower is divided into two-way, is all the way the branch that burns, another way is cold
But branch.The branch that burns enters heat exchanger 4 behind combustion chamber 2, is then entering protection place 5.Cooling branch is directly entered
Outdoor is expelled to after heat exchanger 4, the gas of branch cooling in this way cools down the gas after burning, makes to generate after burning lazy
Property gas be able to enter protection place 5.
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.
In the present invention, the fuel ignition gas or oil of combustion chamber 2, by with the oxygen combustion in air, obtain oxygen concentration
For < 11% inert gas, flame will extinguish naturally when oxygen concentration content is lower than 11% in general air.Of the invention
Noble gas component is mainly nitrogen, carbon dioxide and water, is inert gas that can not be combustion-supporting, and its concentration more preferably greater than
89%, and there is certain positive pressure, therefore can not only supplant normal oxygen concentration content and be 21% air, but also can prevent
Only generating thermal convection makes ignition point that can not attract fresh air that the intensity of a fire is further increased.
In the present invention, battery 6 can also be increased, as shown in Figure 2.Battery 6 is powered for monitoring device.The present invention
Battery 6 by the temperature difference charging on heat exchanger 4, battery 6 is powered driving to motor 3, makes in the course of work in this way,
Battery being capable of long-term stable operation.
In the case where no fire, the device of the invention does not work, and when a fire, battery 6 drives 1 turn of blower
Dynamic, burning branch gas generates inert gas by the burning of combustion chamber 2, inert gas concentration range be 8%, 9%, 10% or
11%, then inert gas enters the cooling of heat exchanger 4, enters protection place 5 by inert gas after heat exchange cooling.Cooling branch
Outdoor is finally discharged in gas.
The device of the invention is particularly suitable for putting out a fire to unattended region.Such as high-tension transformer, using automatic water jetting
Mode put out a fire, then be easy to cause high-voltage electricity to reveal, bigger the condition of a disaster occur.Or at precious article preservation, if any use
Liquid fire extinguishing, then precious article can also damage, and result in greater loss.It is automatic to start when fire occurs for the device of the invention, lead to
The mode for crossing reduction scene of fire oxygen concentration is put out a fire as early as possible.
Blower 1 of the invention or other blowing devices, such as air blower or ventilation blower, as long as being capable of providing stable
Air-flow.
