Arc groove or the length of half arc lower groove on half.The upper and lower surface providing the benefit that sealing gasket is wave
Shape, it is achieved Flexible change, finally makes effective mechanical seal of fuel nozzle head and fuel nozzle main body, it is to avoid fuel oil sprays
Mouth leakage of oil.The Chinese patent of Application No. 201120173908.4 discloses a kind of fuel nozzle of carburetor, this carburetor
Fuel feed hole, transitional pore and the oil outlet that fuel nozzle is sequentially communicated in including nozzle, between described fuel feed hole to oil outlet
Transitional pore be that circular arc line rotates about the axis 360 ° of rotating hole faces obtained.
The fuel nozzle of carburetor mixed oil and gas jet velocity of this utility model is high, and fuel oil atomization more quickly and effectively improves
The efficiency of combustion of fuel oil, thus reduce oil consumption and reduce waste gas discharge.
But existing fuel nozzle is usually present following shortcoming: fuel oil is relatively low with the mixability of air, and fires
Oil atomization effect is the most not ideal enough, thus causes fuel oil to burn completely, and efficiency of combustion is low, in the gas of generation
Pollutant are the biggest.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of rotary kiln burner fuel nozzle.This practicality
Novel fuel nozzle can make fuel oil higher with the degree of mixing of air, and atomizing effect is more preferable such that it is able to improves fuel oil
Efficiency of combustion, and burning after pollutant less.
Concrete technical scheme of the present utility model is: a kind of rotary kiln burner fuel nozzle, including nozzle body, institute
Be provided with fuel gallery in stating nozzle body, described fuel gallery by fuel flow direction be divided into oil-in, cushion chamber,
Air-fuel mixture chamber and jet, the internal diameter of described cushion chamber is more than the internal diameter in described air-fuel mixture chamber, air-fuel mixture chamber
Sidewall is provided with some inlet channels, and the axial line of described inlet channel and the angle of the axial line in air-fuel mixture chamber are sharp
Angle, and the inlet end of inlet channel to the distance of described jet more than the outlet side of inlet channel to described jet
Distance.
In the technical solution of the utility model, fuel oil enters from oil-in, in cushion chamber after short-term buffering, enters
Air-fuel mixture intracavity, at air-fuel mixture intracavity, air enters air-fuel mixture chamber by inlet channel and mixes with fuel oil.
The inclined shape of this inlet channel, can be sufficiently mixed with fuel oil after entering air-fuel mixture chamber, improves the degree of mixing of oil gas,
It is thus possible to play more preferable atomizing effect.
As preferably, the axial line of described inlet channel is 45 degree with the angle of the axial line in air-fuel mixture chamber.45 degree
The inlet channel of overturning angle, air is more preferable with the mixed effect of fuel oil.
As preferably, described cushion chamber and the junction in air-fuel mixture chamber are tapered round table-like.Tapered round table-like connection
The effect at place is, the effect played is the flow rate improving fuel oil, thus is easier to atomization with air after mixing.
As preferably, all inlet channels are uniformly distributed in the circumferential side wall in described air-fuel mixture chamber.
As preferably, the outlet side of all described inlet channels is positioned on the same cross section in described air-fuel mixture chamber.Air inlet
The outlet side of passage is positioned on the same cross section in air-fuel mixture chamber, and so, the air that all directions enter enters oil gas and mixes
Interfering with each other to centrality after closing chamber, be atomized together with fuel oil, atomizing effect is more preferably.
As preferably, described air-fuel mixture intracavity is positioned at the outlet side of inlet channel and is provided with silk screen.The setting of silk screen,
Can play flow-disturbing effect, so that the atomizing particle of gas mixture is less, fogging degree is higher.
Being compared with the prior art, the beneficial effects of the utility model are: fuel nozzle of the present utility model can make fuel oil
Higher with the degree of mixing of air, atomizing effect is more preferable such that it is able to improve the dirt after the efficiency of combustion of fuel oil, and burning
Dye thing is less.
