Detailed description of the invention
Be a kind of atomizing effect that effectively can improve fuel oil provided by the invention as shown in Figure 1, make the thinner less fuel spraying device of the particle of fuel oil after atomization.The atomization spray core 3 that described fuel spraying device comprises the nozzle set 2 containing ejiction opening 1 and is arranged in described nozzle set 2, the axial lateral wall of described atomization spray core 3 is evenly equipped with many along the axially extended spiral fog water content 4 of described atomization spray core, the fuel oil in described fuel spraying device is entered by described atomization spray core 3, described spiral fog water content 4 be atomized into particle under the cooperation of described nozzle set 2 after, spray described nozzle set 2 from described ejiction opening 1.Owing to being evenly equipped with many along the axially extended spiral fog water content 4 of described atomization spray core on the axial lateral wall of described atomization spray core 3, and make the fuel oil entered by described atomization spray core 3 in described fuel spraying device, described spiral fog water content 4 be atomized into particle under the cooperation of described nozzle set 2 after, spray described nozzle set 2 from described ejiction opening 1.Like this, change prior art intermediate fuel oil and directly under High Pressure, spray by atomization spray core the structure that nozzle set carries out being atomized, thus fuel oil can be made to become thinner less particle through the rotary-atomizing of spiral fog water content 4, reach the effective object improving atomizing effect.Particle due to atomization is thinner less, and the fuel oil after atomization is more abundant in the burning of postorder, also can not go out the phenomenon that oil dripping damages refractory material.
In above-mentioned embodiment, in order to overcome insufficient due to oxygen content in the fuel particles after prior art atomization and problem that burning that is that cause is insufficient, the application has done further improvement to described fuel spraying device, namely described fuel spraying device also comprises the oxygen enrichment sleeve pipe 5 be socketed in outside described nozzle set 2, and the gases at high pressure being rich in oxygen to be delivered to outside described nozzle set 2 around by described oxygen enrichment sleeve pipe 5; The fuel oil after particle is atomized into by described nozzle set 2 and described spiral fog water content 4, after spraying from described ejiction opening 1, the oxygen enrichment sleeve pipe 5 described in spraying with the described gases at high pressure being rich in oxygen.Like this, just can admix oxygen fully in fuel oil after atomization, play combustion-supporting effect, to improve the sufficient degree of burning.
More carefully to burn more sufficient principle according to fuel-oil atmozation, in order to further improve nebulization efficiency, make the fuel particles after atomization thinner less, secondary atomizing apparatus 6 is also furnished with at the ejection end of described oxygen enrichment sleeve pipe 5, the fuel oil of described nozzle set 2 is sprayed after being atomized into particle by described nozzle set 2 and described spiral fog water content 4, spraying in the process of described oxygen enrichment sleeve pipe 5 with the described gases at high pressure being rich in oxygen, be again atomized into less particle by described secondary atomizing apparatus 6.Preferred secondary atomizing apparatus 6 is made up of the atomization block 7 suitable with described oxygen enrichment sleeve pipe 5 inner end diameter, the axial lateral wall of described atomization block 7 is provided with many along the axially extended rotary-atomizing groove 8 of described atomization block, described each bar rotary-atomizing groove 8 is uniform along described atomization block 7 circumference; Spray the fuel oil of described nozzle set 2 after being atomized into particle by described spiral fog water content 4 and described nozzle set 2, spray with the described gases at high pressure being rich in oxygen in 5 processes of described oxygen enrichment sleeve pipe by described rotary-atomizing groove 8 secondary-atomizing.Like this, the tiny fuel particles after primary atomization, then by described gases at high pressure at a high speed by described rotary-atomizing groove 8 time, can further refinement fuel particles.
In above-mentioned embodiment, in order to further improve the primary atomization effect of fuel oil, in conjunction with the atomization spray core 3 described in the application by spray core body 9 and fuel delivery line 10, described spray core body 9 is arranged in the output end of described fuel delivery line 10, described spiral fog water content 4 is arranged on described spray core body 9, described atomization spray core 3 is socketed the design feature in described nozzle set 2 by the fuel delivery line 10 described in described spray core body 9 and the part that is connected with this spray core body 9, one is also provided with vertically along the conical fuel-oil atmozation dispersing head 11 prolonged at the free end of described spray core body 9, what described conical fuel-oil atmozation dispersing head 11 circumferentially left gap 12 with described ejiction opening 1 passes this ejiction opening 1.Like this, the ejection pressure of fuel oil can be increased, play the object improving atomizing effect.Simultaneously, in order to disperse, fragmentation fuel oil, for atomization is prepared, described spray core body 9 and the junction of described fuel delivery line 10 are provided with the fuel oil delivery outlet 13 perpendicular to described spray core body longitudinal center line, the fuel oil of described fuel spraying device is inputted by described fuel delivery line 10, sprayed in the cavity between described spray core body 9 and described nozzle set 2 by described fuel oil delivery outlet 13, and under the effect of the fuel oil of follow-up input, spray described nozzle set 2 along described spiral fog water content 4 and be atomized into particle.Like this, fuel oil sprays in the cavity between described spray core body 9 and described nozzle set 2 by described fuel oil delivery outlet 13, just can play preliminary dispersion, smash the object of fuel oil, for follow-up atomization is prepared.
And be conveniently rich in the gases at high pressure input oxygen enrichment sleeve pipe of oxygen, the gases at high pressure input of described oxygen enrichment sleeve pipe 5 is also provided with adpting flange 14, oxygen enrichment sleeve pipe 5 between described adpting flange 14 and described atomization spray core 3 is provided with transitional connection pipe 15, the input of described fuel delivery line 10 fix through described adpting flange 14; Described oxygen enrichment sleeve pipe 5 is connected with outside gases at high pressure carrier pipe by described transitional connection pipe 15.Meanwhile, the oxygen enrichment sleeve pipe 5 closing on described adpting flange 14 one end is also furnished with air gauge 16.
In sum, the structure of employing provided by the invention twice atomized fuel to fuel oil at two sub-high pressures and high oil pressure, the atomization carried out under high Pneumatic action, fuel spray can be changed into the fuel particles that the particle that is atomized into than existing atomizing type is much smaller, like this, not only make oil inflame more abundant, improve the heating efficiency of fuel oil, reach the object of economize energy, and due to after the ejiction opening by the fuel particles ejection nozzle set after the pressure atomization of fuel oil self, do not depart from oil gun, but take out of further by gases at high pressure in oxygen enrichment sleeve pipe 5 in the process of oxygen enrichment sleeve pipe 5 and atomization block 7 and be again atomized, thus except the fuel particles after giving atomization provides more sufficient oxygen, the larger fuel oil of particle can also be avoided to occur the phenomenon of water clock at ejiction opening because of gravity, further save the energy, this is also one of comparatively significant effect of the application.According to statistics, fuel spraying device provided by the invention is adopted to carry out being atomized rear igniting, compared with the atomization carried out with the like product adopted in the market is lighted a fire, the use oil mass of more than 25% at least can be reduced in saving energy consumption, and compared with the product of current relatively oil consumption on the market, the highlyest can reach 75% by economize energy.
