Abstract
The invention relates to a fuel oil atomizing device which comprises an evaporation pipe, an air cup and an oil rotating device, wherein the evaporation pipe is formed by three sections of reversed-L-shaped pipes which form angles of 90 degrees; the oil rotating device is arranged at the inner part of a fuel oil outlet of the evaporation pipe; 4-6 spiral grooves are arranged on the outer surface of the oil rotating device; the air cup is mounted at the outer part of the evaporation pipe at the fuel oil inlet; a cup opening of the air cup is leveled with the fuel oil inlet of the evaporation pipe; and an air outlet is arranged on the side wall of the air cup. The fuel oil atomizing device disclosed by the invention realizes the aim of sufficiently atomizing under the condition of a very short oil mist range so that the evaporation rate is improved and good conditions are provided for stable and efficient combustion.
Description
Technical field
The present invention relates to a kind of atomising device, especially a kind of fuel atomization device.
Background technology
Evaporation tubular type atomising device belongs to one of fuel atomizer, on large and small type combustion chamber, application is arranged all, operated by rotary motion is at engine main chamber burner inner liner head, Main Function has: the high-temperature fuel gas by the primary zone passes through the evaporation tube wall to fuel Heating in the evaporation tube, fuel oil in the evaporation tube is clashed into and heat by high temperature, high speed inlet air, to reach the effect of EVAP atomizing.Combustion gas by evaporation tubular type atomizer is the high-temperature oil gas gaseous mixture, and easier and primary zone air blending, burning are for efficient, stable burning provides good condition; Commonly used is T-shaped evaporation tube and Г type evaporation tube at present, is single tubular structure, and spray shapes is single direct-injection type cone structure, axial jet speed is large, and for some aero-engine, its burner inner liner compact conformation, head space is little, and mist of oil can be sprayed onto the burner inner liner wall; Because the combustion chamber fuel flow is large, take conventional evaporation tube atomizing effect to descend again.Therefore need good, the short-range atomizer of mist of oil of a kind of atomizing effect, conventional evaporation tube can't satisfy stable, the efficient burning requirement of this combustion chamber.
Summary of the invention
The purpose of this invention is to provide a kind of fuel atomization device, can realize that fuel oil atomizes fully, the short-range target of mist of oil, make flame stabilization, efficient burning, the combustion chamber reliable operation.
Concrete technical scheme of the present invention is: fuel atomization device comprises evaporation tube, air cup and revolve oily device, described evaporation tube is three sections of the Г type each other 90 ° pipes, be provided with in the inside at the fuel outlet place of evaporation tube and revolve oily device, the described outer surface that revolves oily device is provided with 4～6 helicla flutes, evaporation tube outside at the fuel filler place is equipped with the air cup, the rim of a cup of described air cup is concordant with the fuel filler of evaporation tube, sidewall at the air cup is provided with air outlet slit, the air outlet slit of the sidewall setting of described air cup is 6, and described spiral fluted quantity is preferably 5.The mounting means of described air cup and evaporation tube is welding.
The present invention in use, fuel oil and air enter evaporation tube through fuel nozzle, high temperature, high-speed air impact fuel oil, make airborne fuel oil be broken into granule, the heat of high temperature in primary zone is conducted heat by wall and is accelerated adherent EVAP simultaneously, ejects taper rotation gas mixture jet by revolving oily device at last.Simultaneously, portion of air can also enter the air cup, and the sidewall by the air cup enters the primary zone, participates in burning.
The inside at the fuel outlet place of evaporation tube of the present invention is provided with revolves oily device, increased the centrifugal atomizing effect, reduced the axial jet speed of evaporation tube outlet gas mixture, and increased the average area that fuel oil contacts with high-temperature wall surface, the condition that has realized very short mist of oil range has been issued to the sufficient purpose of atomizing, improve evaporation rate, for stable, efficient burning provide advantage, again because evaporation tube is in the primary zone of combustion chamber, operating ambient temperature is higher, this evaporation tube exit arranges the air cup, has realized preferably cooling.Because the air cup normally is welded on the evaporation tube, so effective cooling can also guarantee the reliability of welding.
