Abstract
The utility model relates to a fuel nozzle device for a combustor. The fuel nozzle device comprises a nozzle seat, wherein the middle part of the nozzle seat is a hollow cavity; a gas inlet is formed at a part, which is close to the right end, at the bottom of the nozzle seat; a fuel inlet is formed in the middle of the right end of the nozzle seat; a spiral sheet is arranged in the middle of the left end of the nozzle seat; a plurality of inwards sunken spiral fuel nozzles are arranged on the spiral sheet; an atomization sheet is arranged at the left end of the spiral sheet; a spiral cavity is formed in the middle of the atomization sheet; the spiral sheet and the atomization sheet are fixedly connected with the nozzle seat through locking nuts; a fuel outlet is formed between the top ends of the locking nuts; and two ends of the spiral cavity are inwards concave. The fuel nozzle device for the combustor has the beneficial effects of simple structure, low manufacturing cost and good atomization effect, and is easy to operate; and furthermore, fuels can be combusted fully, the combustion cost is reduced, and the waste of energy is avoided.
Description
Technical field
The utility model relates to a kind of burner atomizer device.
Background technology
People know that the atomizing effect of liquid fuel is good more, and burning is just abundant more, and the heat of generation is just many more, and production cost just reduces naturally significantly.Yet, take a broad view of burners in prior atomizer in the market, it mainly is made up of shell and mouth core; Liquid fuel gets into from an end of atomizer shell, burns with its compression entering mouth core and from the other end ejection of atomizer through high pressure, and this structure is because the contact area of fuel and air is fewer, time ratio is shorter; Fuel mixes inadequately fully, evenly with air, some fuel also do not have enough time to burn and just are excluded burner hearth, get in the atmosphere; Cause the waste of the energy; And this structure just can't atomize through atomizer if fruit runs into the oil of comparison thickness, has increased the cost of burning.
The utility model content
The purpose of the utility model provides a kind of burner atomizer device, and is fewer with the contact area that overcomes fuel that present prior art exists and air, time ratio is shorter, and fuel such as mixes fully inadequately, even at deficiency with air.
The purpose of the utility model is to realize through following technical scheme:
A kind of burner atomizer device comprises nozzle carrier, and the middle part of said nozzle carrier is a cavity; The bottom of nozzle carrier is provided with air inlet near the right-hand member place; The right-hand member middle part of nozzle carrier is provided with oil-in, and the left end middle part of nozzle carrier is provided with flight, and flight is provided with some indent spirality atomizers; The left end of flight is provided with atomizing piece; The middle part of atomizing piece is provided with the spirality cavity, and said flight is fixedly connected with nozzle carrier through locking nut with atomizing piece, and the top middle portion of locking nut is provided with oil-out; The two ends of said spirality cavity are concave shaped.
The beneficial effect of the utility model is: simple in structure, and operation easily, cost of manufacture is low and atomizing effect good, can make full combustion of fuel, reduces the burning cost, has avoided the waste of the energy.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of burner atomizer device of the utility model embodiment.
Among the figure:
1, nozzle carrier; 2, air inlet; 3, oil-in; 4, flight; 5, indent spirality atomizer; 6, atomizing piece; 7, spirality cavity; 8, locking nut; 9, oil-out.
The specific embodiment
As shown in Figure 1, the described a kind of burner atomizer device of the utility model embodiment comprises nozzle carrier 1; The middle part of said nozzle carrier 1 is a cavity, and the bottom of nozzle carrier 1 is provided with air inlet 2 near the right-hand member place, and the right-hand member middle part of nozzle carrier 1 is provided with oil-in 3; The left end middle part of nozzle carrier 1 is provided with flight 4; Flight 4 is provided with some indent spirality atomizers 5, and the left end of flight 4 is provided with atomizing piece 6, and the middle part of atomizing piece 6 is provided with spirality cavity 7; Said flight 4 is fixedly connected with nozzle carrier 1 through locking nut 8 with atomizing piece 6, and the top middle portion of locking nut 8 is provided with oil-out 9; The two ends of said spirality cavity 7 are concave shaped.
During concrete the use; Oil inlet pipe is connected to the rear end of flight 4 through oil-in 3; Through air inlet 2 connect air inlet pipe and in the nozzle carrier 1 input air in the cavities, fuel gets into indent spirality atomizer 5 through the rear end of flight 4, and is under the acting in conjunction through indent spirality atomizer 5 and flight 4 that fuel mix is even; Fuel after mixing gets in the spirality cavity 7 on the atomizing piece 6; Combine with flight 4 peripheral air, make it to form the oil gas mixture of rotation at a high speed, oil gas mixture is again through oil-out 9 ejections of spirality cavity 7 from the top middle portion of locking nut 8.It is more even that the utility model can let fuel mix with air, improves atomizing effect, makes fuel combustion more abundant, thereby reduced the burning cost, avoided the waste of the energy, has certain economic and be worth.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
