Additional aspect and advantage of the invention will become obviously in following description section, or practice through the invention
The invention will be further described with reference to the accompanying drawings and embodiments.
Referring to figures 1-3, the utility model diesel fuel burner, including burner shell 1, heat-resisting 2 burner shell 1 of wind-guiding column are in
Hollow structure, burner shell 1 is interior to be equipped with heat-resisting wind-guiding column 2, and heat-resisting wind-guiding column 2 makes the inner cavity of burner shell 1 form head and the tail
The quirk 3 communicated, the outside of burner shell 1 are equipped with ignitron 11, and heat-resisting 2 ignitron 11 of wind-guiding column makes quirk 3 and the external world even
Logical, ignitron 11 is equipped with oil inlet pipe 4 and ignition electrode 5, and the oil outlet of heat-resisting 2 oil inlet pipe 4 of wind-guiding column, which is equipped with, makes diesel oil liquid
Body particle enters the atomization oil nozzle 41 of quirk 3 in the form of spraying cone, and the quirk 3 communicated from beginning to end can make in warm-up phase
Liquid diesel particle near the tongues of fire and fiery root meets and heats, and is vaporized liquid diesel particle before completely burned, and
Combustion air preheated in high temperature, in the case where cooperating diesel liquid particle to enter quirk 3 in the form of spraying cone, in burning temperature
It spends in sufficiently high quirk, diesel liquid particle generates the quick-fried phenomenon of liquid and causes chain reaction, makes diesel oil high-velocity combustion, realizes nothing
Flame combustion efficiency increases efficiency of combustion, eliminates carbon distribution, reduces pollution, and the present invention is made not generate pollution to food and environment.
Further, the inlet end of ignitron 11 is equipped with air blower (being not drawn into figure), can make to burn required combustion-supporting
Air enters in quirk 3.
Further, the inner wall of the outer wall of heat-resisting wind-guiding column 2 and/or burner shell 1 is equipped with heat radiation layer 6, this reality
It applies and is equipped with heat radiation layer 6 on the outer wall of heat-resisting wind-guiding column 2 and the inner wall of burner shell 1 in example, what heat radiation layer 6 generated
Combustion velocity and combustion reaction temperature in quirk 3 can be improved in heat, to faster enter high-velocity combustion state.
Further, the perspective plane of heat-resisting wind-guiding column 2 and the inner cavity perspective plane of burner shell 1 are rounded, heat-resisting
Wind-guiding column 2 is set on the bottom centre position of burner shell 1, forms the quirk 3 in annulus shape, and heat-resisting wind-guiding column 2 draws
Combustion pipe 11 is set in the tangential direction of quirk 3, and the quirk 3 of annulus shape cooperates the ignitron 11 in its tangential direction, can be with
Be conducive to the diffusion of flame when warm-up phase, to faster make atomized liquid diesel oil fast vaporizing, improve combustion efficiency.
Further, the top of burner shell 1 is equipped with exhanst gas outlet 12, is different from tradition by the side of thermal-flame heat transfer
Formula, completely burned generates high-temperature flue gas to diesel oil as a vapor in the present embodiment, cooperates the high speed jet at ignitron 11, from
Exhanst gas outlet 12 discharges heat outward, has the very high thermal efficiency.
Further, the position that the top of heat-resisting wind-guiding column 2 corresponds to exhanst gas outlet 12 is equipped with heat radiation circular arc face 21,
The surface area for increasing the heat radiation layer 6 of heat-resisting wind-guiding column 2, to improve heat-transfer effect.
The working principle of the invention and the course of work are such that
Firstly, the required air that burns enters in quirk 3 under the action of air blower, meanwhile, diesel oil is in atomization oil nozzle 41
Under the action of to quirk 3 spray, formed diesel oil liquid particulate injection bullet, ignition electrode 5 discharge, diesel oil liquid particulate kindling
Then, the diesel particulate after kindling will be burnt in a manner of diffusion combustion, together with combustion air, from ignitron
11 enter annular quirk 3, the flame edge annular 3 rotary combustion of quirk for generation of burning and the entire sky that will be filled with annular quirk 3
Between, the liquid diesel particle near the tongues of fire and fiery root meets and heats, at this point, operative liquid diesel particulate is complete in liquid form
It will be vaporized before full burning, to start to burn in the form of diesel steam, due to volume energy after the diesel particulate vaporization of liquid
Increase by hundreds times, therefore can also be greatly increased with the contact area of fuel-air is helped, to make the combustion reaction temperature in quirk 3
Rapid increase, meanwhile, the temperature of combustion air also increases substantially, and combustion reaction temperature is further increased, what is mutually promoted
In circulation, flame temperature will be risen rapidly；
At the initial stage of ignition, since the speed of combustion reaction is slower, the temperature of flame is relatively low, so diesel oil is complete
Distance needed for burning is also longer, and it is also longer to be formed by flame, to be generally full of entire quirk 3, with combustion reaction plus
By force with the raising of flame temperature, flame can be shorter and shorter, multi-turn rotation ability after-flame is needed since just, latter circle can fire in place
To the greatest extent, the length of flame is constantly reduced, but the temperature in quirk 3 will be increased constantly；
Then, diesel liquid particle after atomization is injected in the form of spraying cone from the tangential direction of rotation quirk 3
When in the quirk 3 of high temperature, since environment temperature is very high, the quick-fried phenomenon of liquid is produced, the quick-fried phenomenon of liquid refers to diesel liquid particle in height
Instant vaporization in the environment of temperature and the explosion phenomenon generated are (when water droplet is fallen into the oil of high temperature in similar life, produced by water droplet
Explosion phenomenon be a kind of quick-fried phenomenon of liquid), those skilled in the art are appreciated that the quick-fried phenomenon of liquid keeps combustion reaction further
Reinforce, into the high-velocity combustion stage；
Because the burning velocity of high-velocity combustion is quickly, time short, required space needed for completing combustion reaction
It is small, it is very short to burn flame caused by reacting, and be able to achieve flameless combustion effect, the product of diesel oil high-velocity combustion can be used thoroughly dry
Net to describe, even excess air coefficient very little, superfluous oxygen content is good close to also having in the case where zero in flue gas
Combustion conditions, the content of harmful gas such as CO is also very low in flue gas, and the content of harmful gas is typically all to approach in normal lower flue gas
In zero, as incomplete combustion, phenomena such as analysing carbon, will not generate during normal use, and discharge index is much better than
Therefore natural gas and liquefied gas can become a kind of clean energy resource using diesel oil after diesel oil high-velocity combustion technology.
Above-described embodiment is preferred embodiment of the invention, and the present invention can also have other embodiments.The technology of this field
