Concrete technical scheme of the present utility model is: a kind of compressed air cap structure, including blast cap main body, institute
Being provided with compressed air channel in stating blast cap main body, described compressed air channel pressing stream of compressed air moves direction and divides successively
For air inlet, cushion chamber, accelerating cavity and multiple fumarole；Described fumarole is uniformly distributed in blast cap main body pressure
Stream of compressed air goes out on the end face of one end, and each fumarole is equal to the distance of blast cap main body axial line；Described jet
Angle between axial line and the axial line of blast cap main body in hole is 10-20 degree, and the jet direction of fumarole in
Divergent shape.
Giving vent to anger in the blast cap main body of compressed air cap structure of the present utility model, it is multiple to be evenly distributed with on end face
Angle design between fumarole, and the axial line of the axial line of this fumarole and blast cap main body is 10-20 degree,
In this angle, after blast cap coordinates with fuel nozzle, the compressed air being injected in fuel nozzle is in dissipating
Shape, and less by fumarole aperture, and air-flow velocity is higher, and compressed air is easier to mix with fuel oil, fuel oil
Easier it is atomized.Above-mentioned angle needs strict control, and angle easily causes the most greatly the air-flow of injection too
Dispersion, angle is the least, diminishes with fuel contacts area.
As preferably, described air inlet, cushion chamber, the cross section of accelerating cavity are circular and coaxial.
As preferably, the internal diameter of described cushion chamber is more than the internal diameter of described accelerating cavity.
The internal diameter of accelerating cavity is less than cushion chamber internal diameter, it is possible to make compressed air flow velocity before ejection increase, thus more
Be conducive to the mixing of gas and fuel oil.
As preferably, the quantity of described fumarole is 8.
As preferably, the angle between axial line and the axial line of blast cap main body of described fumarole is 15 degree.
As preferably, in described blast cap main body, compressed air flows out the inner face of one end is outwardly cambered surface.
This inner face is designed to cambered surface, it is possible to is more beneficial for compressed-air actuated injection and reduces compressed air to blast cap master
The pressure of internal wall, thus extend the service life of blast cap.
As preferably, the radian of described cambered surface is 150 degree.
Being compared with the prior art, the beneficial effects of the utility model are: compressed air blast cap of the present utility model is tied
Structure can improve the mixability of compressed air and fuel oil, and atomizing effect is more preferably, thus improves the burning of fuel oil
Efficiency.
