Description
Technical field
The utility model belongs to power station technology field, in particular to a kind of water cooling heat-insulating for furnace oil burner
Heavy oil gun.
Background technique
Certain foreign power plant project that my company always wraps uses heavy oil ignition system.During the project implementation, heavy oil point is found
There is huge defects for fiery system.In power station during test run, heavy oil gun is easily blocked, and causes ignition difficulties, and repeatedly
Igniting also allows burning torch to put aside amount of heat in a short time, causes situations such as blowing inside burning torch.
Currently, domestic steam boiler, based on fire coal, ignition oil selects light oil ignition system, heavy oil combustion system
Develop and immature, the problem of encountering in heavy oil combustion, also directly restricts putting into operation for power plant, huge damage is caused to power station
It loses.
Discovery when lancing test is tested is cleared up oil gun, dissected and carried out at the scene, even if by oil gun from end orifice
In clean out, but in actual motion, after leading to oil in oil gun, and oil gun end will be caused to block, and block oil gun and
Not instead of heavy oil accumulates in inside oil gun, and the carbon particle that coking cracks at high temperature.
Field test discovery can not also purge completely even if extending the time of steam blowing inside oil gun, be bound to cause weight
Oil accumulation.In addition, a large amount of heavy oil can be gathered in oil gun when interior leakage occurs in the oil valve before oil gun, it is high after boiler combustion
Under the environment of temperature, cracking certainly will also be become coke granule by these heavy oil influences atomizing effect so that oilhole be caused to block, point
It is fiery difficult.
Under normal circumstances, oil gun is a distance to be exited from burner hearth, and have cooling wind on oil gun after ignition
System, however cooling wind is limited to the cooling effect of oil gun, the extreme temperatures of oil gun end can cause to accumulate in oil circuit completely
In heavy oil crack.
From the point of view of project practical operation situation, heavy oil is gathered in oil gun, it is difficult to avoid, heavy oil cracks at high temperature, more
It is inexorable trend.The oil gun generally used on existing market can not prevent heavy oil pyrolysis effectively, block asking for oil gun
Topic.
Utility model content
The goal of the invention of the utility model is: in view of the above problems, providing one kind can be effectively reduced oil
Rifle internal temperature alleviates the water cooling heat-insulating heavy oil gun of oil gun blocking to inhibit heavy oil pyrolysis.
The technical solution of the utility model is achieved in that a kind of water cooling heat-insulating heavy oil gun, it is characterised in that:
It is provided with cooling water pipe in the outer wall of the pipette tips, the outer wall of the cooling water pipe and pipette tips cooperatively forms cooling water pipe
The cooling water flow conduits in interior outside, the cooling water flow conduits are located at the peripheral part of oil circuit and its end oilhole in pipette tips, for dropping
The temperature of low oil gun outer wall.
Water cooling heat-insulating heavy oil gun described in the utility model, cooling water flow conduits on the outside of the cooling water pipe with
Cooling water inlet is connected to, and the cooling water flow conduits on the inside of the cooling water pipe are connected to cooling water outlet.
The utility model is transformed by the outer wall to heavy oil gun, and by the way of water cooling, cooling water is passed through oil
Among the outer wall of rifle, the temperature of oil gun outer wall is directly effectively reduced, so that burner hearth high temperature greatly be inhibited to be transferred to heavy oil oil
Among the oil circuit of rifle, the temperature in oil circuit is reduced, heavy oil pyrolysis is effectively relieved as coke granule, prevents oil gun stopping state
Occur.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Marked in the figure: 1 is pipette tips, 2 be cooling water pipe, and 3 be cooling water flow conduits, and 4 be outer wall, and 5 be oil circuit, and 6 be inner wall.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As shown in Figure 1, a kind of water cooling heat-insulating heavy oil gun, is provided with several oilholes in 1 end of pipette tips of the oil gun,
Several oilholes are equidistantly evenly distributed on same circumference centered on pipette tips axle center, and the pipette tips of the oil gun are by outer wall
4 and inner wall 6 be socketed to form, between the inside and outside wall formed oil circuit 5, the inner wall is passed through steam, in the outer wall 4 of the pipette tips 1
Inside it is provided with cooling water pipe 2, the outer wall 4 of the cooling water pipe 2 and pipette tips 1 cooperatively forms outside in cooling water pipe 2
The cooling water flow conduits 3 of cooling water flow conduits 3,2 outside of cooling water pipe are connected to cooling water inlet, the cooling water pipe 2
The cooling water flow conduits 3 of inside are connected to cooling water outlet, and the cooling water flow conduits 3 are located at oil circuit 5 and its end oil in pipette tips 1
The peripheral part in hole, to reduce the temperature of oil circuit, becomes coke for reducing the temperature of oil gun outer wall heavy oil pyrolysis is effectively relieved
Charcoal particle prevents the generation of oil gun stopping state.
In the present embodiment, in order to reduce the temperature of oil circuit, oil gun outer wall is transformed.Currently, the cooling side of oil gun
Formula generally selects air cooling, and cold wind is directly blown into burner hearth by oil gun and is realized.However, according to live practical application effect come
It sees, cooling wind is limited to the cooling effect of heavy oil gun outer wall, and this programme cooling water will be passed through all the way by the way of water cooling
Among the outer wall of oil gun, by using the form of casing, cooling water is flowed by outside of sleeve, inside outflow, due to the heat transfer of water
Coefficient is much larger than air, therefore water-cooling system is above cooling oil gun, will directly effectively reduce the temperature of oil gun outer wall, from
And achieve the effect that inhibit heavy oil pyrolysis coke particle, prevent oil gun from blocking.
The embodiment of the utility model low cost, it is economical and practical, while insulation effect is significant, and heat diffusion can be effectively suppressed
To inside oil gun, to effectively prevent the heavy oil remained among oil gun oil circuit under hot conditions to be cleaved, to effectively prevent
The case where oil gun blocks.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
