Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] A method for determining the fuel spray cone angle in a double-swirl atomization device, wherein the size of the fuel spray cone angle in the double-swirl atomization device is determined according to the best drop point position of the fuel on the inner wall of the venturi tube , the fuel spray cone angle satisfies the following formula:

[0028] α=2*arctg(R X / L P ),

[0029] In the formula, R X - the radius of the drop point of the fuel on the inner wall of the venturi,

[0030] L P - Dimensions of the axial position of the fuel drop point.

[0031] The radius R of the point where the fuel falls on the inner wall of the venturi tube X is the axial dimension of the cross-section on the inner surface of the Venturi tube, calculated according to the following formula:

[0032] (F i -F i+1 ) / F i =0.907X i / L-0.65,

[0033] In the formula...

Abstract

The invention provides a determination method of a fuel spray cone angle in a double-rotational-flow atomization device. The fuel spray cone angle in the double-rotational-flow atomization device is determined according to an optimal falling position of fuel on the inner wall of a venturi; and the fuel spray cone angle meets the formula of alpha=2*arctg (RX / LP), wherein RX- is the radial of the falling point of the fuel on the inner wall of the venturi, and LP- is the axial position size of the falling point of the fuel. The determination method of the fuel spray cone angle in the double-rotational-flow atomization device determines the spray angle of a fuel nozzle through the optical falling point of the fuel on the inner wall of the venturi, has a certain scientific basis, achieves the accuracy, forms thin and uniform oil films in the venturi, and can effectively guarantee the atomization effect of the double-rotational-flow atomization device.

Description

technical field [0001] The invention relates to the technical field of double swirl atomization devices, in particular to a method for determining the fuel spray cone angle in the double swirl atomization device. Background technique [0002] The double-swirl atomizing device is a pre-film pneumatic atomizing device formed by the integrated design of the fuel nozzle and the flame tube inlet device. Broken atomization, the formation of a thin and uniform oil film in the venturi tube is the prerequisite for good atomization. , the spray cone angle of the fuel nozzle is an important parameter affecting the atomization performance of the double swirl atomizer. [0003] However, in the current design specification, the setting of the spray cone angle of the fuel nozzle used in the double-swirl atomization device is blind and arbitrary, and the result will seriously affect the atomization quality of the fuel. Contents of the invention [0004] In view of this, the present inve...
