The utility model has simple structure, good atomization effect, full combustion, and science and environment protection.

Description

A kind of Y type effervescent atomization oil gun

Technical field

The utility model relates to a kind of oil gun, relates in particular to a kind of Y type effervescent atomization oil gun.

Background technology

At present, the oil gun oil plant of station boiler startup and combustion-supporting employing comprises diesel oil, heavy oil and heavy diesel fuel etc.Because character such as the viscosity that oil plant has is big have determined oil plants such as heavy diesel fuel to be difficult for the characteristics of atomizing and burning.Therefore, need to adopt steam tracing or utilize using waste heat from tail gas that heavy diesel fuel is heated to uniform temperature,, obtain atomizing effect preferably to reduce its viscosity.Station boiler adopts simple mechanical type or steam-type atomized oil gun usually, and oil gun is arranged in the overfiren air port, and the form of fuel oil drop after oil gun atomizing enters burner hearth, in stove with coal dust mixed combustion.Because of boiler flow field gas field circumstance complication, atomizing effect is limited, therefore causes incomplete combustion, produces a large amount of black smokes and the adverse consequences of coking, contaminated environment.

Summary of the invention

The purpose of this utility model is to address the above problem and provide a kind of simple in structure, and atomizing effect is good, sufficient combustion, the Y type effervescent atomization oil gun of science environmental protection.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

It comprises outer wall and inwall, form the gas passage between the inner and outer wall, the gas feeder connection is provided with air valve, interior pars intramuralis is oily passage, the oil feeder connection is provided with the fuel tap door, and oily channel interior is provided with the bubble generator with the gas channel connection, and the inwall of bubble generator far-end is provided with the secondary air inlet mouth, the gentle channel end of oil passage is a mixing chamber, and the mixing chamber outside is a nozzle.

The atomization angle α of said nozzle is less than or equal to 120 °.

Compared with prior art, the utility model has been obtained following technique effect:

1, this utility model is simple in structure, and Oil Gun is stable, and atomizing effect is good, and atomizing particle particle diameter unanimity degree height can be realized the continuous atomizing under different disposal and the different operating modes, reaches abundant burning, the science environmental protection, and the rate of economizing gasoline height, expense is low.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein: 1-fuel tap door, 2-air valve, 3-outer wall, 4-gas passage, 5-bubble generator, 6-secondary air inlet mouth, 7-nozzle, 8-mixing chamber, 9-oil passage, 10-inwall.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 1, a kind of Y type effervescent atomization oil gun, it comprises outer wall 3 and inwall 10, forms gas passage 4 between the inner and outer wall, and the gas feeder connection is provided with air valve 2, interior pars intramuralis is oily passage 9, the oil feeder connection is provided with fuel tap door 1, and oily channel interior is provided with the bubble generator 5 with the gas channel connection, and the inwall of bubble generator far-end is provided with secondary air inlet mouth 6, the gentle channel end of oil passage is a mixing chamber 8, and the mixing chamber outside is a nozzle 7.

The power station is power station with oily freezing point height with other with oily occasion maximum different with oil, and used oil plant need heat and just has good flowability, is beneficial to atomize.In the utility model, the oil that enters oil gun through oil pump guarantees temperature between 100 ℃-150 ℃ earlier through steam preheating, and the used vapor (steam) temperature of gas passage is between 200 ℃-350 ℃, the maximum atomizing angle α of nozzle can reach 120 °, can guarantee good as far as possible materialization effect.

The course of work of Y type effervescent atomization oil gun is:

1, opens air valve 2, utilize steam that oily passage 9, gas passage 4 and mixing chamber 8 are purged,, simultaneously pipeline is carried out preheating to remove remaining oil plant;

2, after purging finishes, open fuel tap door 1, oil is entered in the oily passage 9, bubble generator 5 interior ventilations this moment, the generation bubble makes the oil in the oily passage 9 become biphase gas and liquid flow;

3, the fuel oil that enters oil gun becomes after the two phase flow through bubble generator 5, under the effect of the high steam that secondary air inlet mouth 6 is come in, is gasified for the first time;

4, after the two phase flow that is once gasified enters mixing chamber 8, because pressure reduces, bubble volume expands, oil pressure is broken, simultaneously from gas passage 4 enter the steam of mixing chamber will be broken liquid film further smash, make it to become littler drop in small, broken bits, from nozzle 7 ejections.

Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
