Abstract
The utility model relates to a fuel injection nozzle. The utility model is characterized in that (1) a fuel vaporization injection-duct is arranged at the periphery of the fuel injection nozzle; (2) a combustion-supporting air inlet duct is arranged at the periphery of the fuel injection duct. During operation, the utility model can facilitate vaporization and mix with combustion-supporting air to form fuel gas with better mixing ratio to achieve sufficient combustion of the fuel. The product is particularly applicable to combustion furnaces and tunnel kilns taking heavy oil and diesel oil as fuels.
Description
This reality is novel to relate to a kind of fuel injection nozzle.
The existing fuel injection nozzle that is installed on the sidewall of the furnace body is typically provided with oil input channel and combustion air air intake duct.The major defect that exists is fuel oil atomization badness when entering body of heater, therefore can not completing combustion and contaminated air.
The purpose of this utility model is that a kind of fuel injection nozzle will be provided, and it helps the vaporization of fuel oil and fully burning.
Construction features of the present utility model are: (1) atomizer periphery is provided with the fuel gasification air-jet channel, and (2) fuel gasification air-jet channel outer periphery has combustion-supporting free-air diffuser.
Described fuel gasification air-jet channel can be the spiral wind air-jet channel or also can be along equally distributed some the thread-shaped air-jet channels in cylindrical radial surface.
The utility model is owing to be provided with the fuel gasification air-jet channel in the atomizer periphery, therefore after fuel oil is accompanied by (have pressure) the greatly boil-off gas that quickly sprays on a small quantity and flows to body of heater, be vaporized immediately and with enter the fuel gas that combustion air in the body of heater forms preferable mixing ratio through the combustion air air intake duct, thereby realize the fully purpose of burning.
Reaching embodiment is in conjunction with the accompanying drawings down specifically described the utility model.
Fig. 1 is the embodiment organigram.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is a center oil pipe leading section organigram.
Fig. 4 is the left view of Fig. 3.
With reference to accompanying drawing, embodiment of the present utility model comprises atomizer, and taper fuel gasification air-jet cover 1 and the taper of being located at the atomizer periphery help
Combustion air inlet cover 2, it is characterized in that: (1) atomizer constitutes by having the center oil pipe 5 that oil input channel 3 leading sections have a nozzle opening 4 in the body, oil pipe front portion, center is tapered, its leading section closely cooperates through the inwall of short cylindrical 6 radial surfaces that the protrude taper fuel gasification air-jet cover front end through hole 7 peripheral with it, described short cylindrical 6 radial surfaces are evenly distributed with some the jet raceway grooves 8 of thread-shaped along circumference, and taper fuel gasification air-jet cover 1 periphery is provided with taper combustion air airscoop shroud 2.
Be provided with combustion air air inflow adjustable pipe 9 between above-mentioned taper fuel gasification air-jet cover and the taper combustion air airscoop shroud, the internal thread of combustion air air inflow adjustable pipe on the rear lateral portion of the external screw thread 10 of its rear side outer rim and taper combustion air airscoop shroud links, the upper end of combustion air air inflow adjustable pipe has stretches out external handwheel 11, and the front port of combustion air air inflow adjustable pipe can contact with the front port inward flange of taper combustion air airscoop shroud with sealing combustion air air intake duct.
Be equipped with telescopic anti-clogging beam hanger 12 in the oil input channel of center oil pipe, anti-clogging beam hanger front end is provided with the thin bar 13 that can pass center oil pipe front end nozzle opening, and the rear end of anti-clogging beam hanger is passed the oil-sealing arrangement on the oil pipe rear portion, center and is positioned at center oil pipe rear side.Described oil-sealing arrangement by be enclosed within on the anti-clogging beam hanger and and center oil pipe back cavity wall on the joining plug screw 14 of internal thread and be enclosed within on the anti-clogging beam hanger and the sheet for oil seal 15 between plug screw end face and center oil pipe back cavity annular terrace constitutes.
When needs were adjusted the combustion air air inflow, the rotatable handwheel 11 of user made combustion air air inflow adjustable pipe upstream or downstream, to strengthen or to reduce gap between the front port of the front port of combustion air air inflow adjustable pipe and taper combustion air airscoop shroud.
When needs are removed the slagging scorification at oil pipe front end nozzle opening place, center or carbon distribution, the user can before and after twitch the anti-clogging beam hanger.
The course of work of the utility model embodiment is as follows: at first, twitch anti-clogging beam hanger 12 backward and make the thin bar 13 of its front end break away from nozzle opening to guarantee that oil duct is unimpeded; Then, a small amount of air-flow with big pressure is through air induction conduit 16, the jet raceway groove 8 of thread-shaped on taper fuel gasification air-jet cover 1 and the center oil pipe leading section sprays into and forms spiral wind (generation vacuum), thereby make through fuel inlet 17, the fuel gasification that the oil input channel 3 of center oil pipe and nozzle opening 4 spray into also mixes with the combustion air that enters through taper combustion air airscoop shroud 2 and to form the fuel gas with preferable mixing ratio, so that burning.
The utility model is novel, and is reasonable in design, good energy-conserving effect, and the combustion furnace and the tunnel cave that are particularly suitable for acting as a fuel with heavy oil, diesel oil use, and its market prospects are considerable.
