Abstract
The invention provides a kind of nanometer iron powder light igniter, including flash lamp, nanometer iron powder, flash lamp discharges optical pulse energy in very short time, and nanometer iron powder absorbs the oxide layer that light energy destroys its surface, the nano-iron particle of inside is reacted with surrounding air.
Description
Technical field
The present invention relates to a kind of luminous point ignition technique, particularly a kind of nanometer iron powder light igniter.
Background technology
The noncontact igniting and optimal control of meter Sized Materials are most complicated parts.Conventional fuel is mostly at present
Liquid fuel such as gasoline, diesel oil, it is anti-that as a kind of new fuel, after being ignited strong oxidation can occur for nano material rapidly
Amount of heat should be discharged, and high temperature can be reached in moment.
Existing frequently-used firing technique is mainly divided into direct-fire and indirectly igniting.Direct-fire such as spark ignition
It is that high temperature pilot fuel is produced by equipment, igniting such as plasma ignition reaches by fuel adsorption energy indirectly
Fire point burning.And luminous point fire is also one kind of indirect sparking mode, primary difference is that what the light source of flash lamp igniting was produced
Just dissipate, the fuel adsorption energy in very large area can be made, form the phenomenon of distributed igniting.And it is now most
Igniter is heavy and cost is more expensive, is difficult to carry out igniting in some more special regions.
The content of the invention
It is an object of the invention to provide a kind of nanometer iron powder light igniter, including flash lamp, nanometer iron powder, flash lamp
Optical pulse energy is discharged in very short time, nanometer iron powder absorbs the oxide layer that light energy destroys its surface, makes the nanometer of inside
Iron particle reacts with surrounding air.
Using said apparatus, the device also includes support body, and support body is divided into four layers, places reflective mirror respectively from top to bottom, receives
Rice iron powder, condenser, flash lamp.
The present invention compared with prior art, with advantages below：(1) sparking mode of the invention is simple in construction, it is only necessary to
Usually the flash lamp used in, the ordinary articles such as condenser and level crossing are to be equipped with forming；(2) using nano-solid as fuel,
Discharge heat big, solid residue is formed after burning, it is easy to reclaim.
The present invention is described further with reference to Figure of description.
Brief description of the drawings
Fig. 1 is principle schematic diagram of the present invention.
Fig. 2 is apparatus of the present invention structural representation.
Fig. 3 is that the present invention is caught fire image schematic diagram.
Embodiment
With reference to Fig. 1, a kind of nanometer iron powder light igniter discharges optical pulse energy using flash lamp 1 in very short time,
Nanometer iron powder 3 absorbs light energy, and now the oxide layer on the surface of nanometer iron powder 3 is destroyed, and makes the nano-iron particle and surrounding of inside
Air reacts, and discharges heat, reaches the purpose of igniting.
With reference to Fig. 2, a kind of nanometer iron powder light igniter is divided into two parts of light source and light intensifier, the hardware of system
It is main to include two parts：Flash lamp 1 below material with for the enhanced speculum 4 of light and condenser 2.Using common
Flash light source is exposed to nano structural material, and the natural light focused energy of diverging is made by condenser 2, while part is sent out
Be scattered to the light of surrounding makes the light energy concentration of this part be absorbed by nano material by the reflex of speculum 4.By wireless
Remote control exposure of flash lamp enables nano material to absorb a large amount of light energies in a short time, and rise reaches nanometer fuel bulk temperature rapidly
Burnt to ignition point under aerobic environment and discharge amount of heat.Regular flashlight dissipates strong class certainly to surrounding after exposure
Right light, just because of the diversity of light source so that fuel can realize multi-point spark, but still has substantial amounts of energy not obtain
Absorb, it is impossible to make full use of.In the case of in view of being concentrated to energy of light source, a condenser (folder is added above light source
Hold on support) so that light energy is more gathered in a region, it both can guarantee that the nano material in the region realized multi-point spark,
Energy during igniting can be increased again.The reflective mirror above fuel can guarantee that the light of transmission by double absorption simultaneously so that overall
Thermal absorptivity be improved significantly.
Above-mentioned reflective mirror 4, nanometer iron powder 3, condenser 2, flash lamp 1 are arranged on support body, and the support body is divided into four layers, from upper
And the lower reflective mirror 4 of placement respectively, nanometer iron powder 3, condenser 2, flash lamp 1
With reference to Fig. 3, nanometer iron powder emits a brilliant light after lighting, while the fuel for surrounding of igniting, makes bulk temperature moment
Rise, different according to fuel mass, also there is difference in the time of fire endurance period.General 20mg nanometer iron powders can burn 7~8s.
