The utility model discloses the common diesel gasification combustor which can fully combust and is high in heat efficiency. The common diesel gasification combustor comprises an atomizing nozzle, wherein the atomizing nozzle is provided with an oil inlet pipe and a gas inlet pipe; and the oil inlet pipe is connected with a plate-shaped preheating pipe corresponding to the front end of the atomizing nozzle.
Description
Technical field
The utility model relates to a kind of special vehicle (large-scale military construction vehicle, large-scale military truck, large-scale troop-carrying coach etc.) that is applied under severe cold condition, the improvement of a kind of ordinary diesel oil burner structure that warming-up work is used.
Background technique
At present, existing diesel fuel burner has following deficiency: the one, and it is larger that the atomization quality of ordinary diesel oil is affected by extraneous factor.When temperature was low, the flowability of ordinary diesel oil and volatility all can significantly reduce, and under the same pressure, atomization quality is not good; After atomizer nozzle generation mechanical wear, its restraint performance to ordinary diesel oil will change, and atomizer (atomizing) cone shape, atomizing particle diameter all are unfavorable for burning.
The 2nd, the plant failure rate is higher.Electrothermal method is adopted in the igniting of overwhelming majority heating apparatus, and not only electric heating wire fusing, sintering also often occur the limited electric energy of a large amount of consumption, cause lighting rate low; The precision pair of mechanical plunger-piston oil pump is had relatively high expectations to oil quality, and very easily corrosion occurs, and causes charge oil pressure to descend, and nozzle can not be realized atomizing when serious.
The 3rd, diesel oil burns insufficient in the mode of atomizing, and the thermal efficiency is low.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of sufficient combustion is provided, the ordinary diesel oil gasification combustor that the thermal efficiency is high.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises atomizer nozzle, is provided with oil inlet pipe and suction tude on the atomizer nozzle, and the described oil inlet pipe of its structure outline is by linking to each other with the corresponding dish type economizer bank of atomizer nozzle front end.
As a kind of preferred version of the present utility model, the rear end of described atomizer nozzle arranges the fan housing with air intake pipe; Described oil inlet pipe and suction tude are passed by the end of fan housing.
As another kind of preferred version of the present utility model, the front end of described dish type economizer bank is provided with firestopping cover by support.
The beneficial effects of the utility model:
1, after the burner igniting of the present utility model, form stable combustion regime, the root of flame can heat the dish type economizer bank of oil inlet pipe; Diesel oil is through dish type economizer bank heat temperature raising; When diesel fuel temperature rose to 300～365 ℃, diesel oil reached gasification condition, and burner changes the gasification combustion stage automatically over to; The utility model sufficient combustion; The thermal efficiency is high.
2, the utility model atomization combustion phases-time is short, only about 30s; The frayed degree of atomizer nozzle is lower, and atomizer nozzle of the present utility model can need not be safeguarded for a long time, and is not fragile.

Embodiment
The utility model comprises atomizer nozzle 7, is provided with oil inlet pipe 1 and suction tude 2 on the atomizer nozzle 7, and the described oil inlet pipe 1 of its structure outline is by linking to each other with the corresponding dish type economizer bank 8 of atomizer nozzle 7 front ends.
As a kind of preferred version of the present utility model, the rear end of described atomizer nozzle 7 arranges the fan housing 3 with air intake pipe; Described oil inlet pipe 1 and suction tude 2 are passed by the end of fan housing 3.
As another kind of preferred version of the present utility model, the front end of described dish type economizer bank 8 is provided with firestopping cover 9 by support.
Be provided with igniter 5 on the described atomizer nozzle 7.
Described igniter 5 is high-frequency igniter.
Described atomizer nozzle 7 comprises the air-fuel mixture valve 15 with oil circuit 14 and gas circuit 13; The outlet port of air-fuel mixture valve 15 arranges the nozzle 11 that inside has thimble 10 by connecting sleeve 12.
Described igniter 5 is arranged on the atomizer nozzle 7 by the pressing plate 6 with adjustment hole, is provided with on the igniter 5 with unequal two ignition electrodes of the distance of atomizer nozzle 7 front ends.
When temperature was low, diesel oil viscosity was large, and common atomizer nozzle 7 atomization qualitys are relatively poor, and the problem that can't light usually can appear in diesel oil; The utility model is set to one with air-fuel mixture valve 15 and nozzle 11 by connecting sleeve 12, after air-fuel mixture valve 15 carries out primary atomization, has carried out secondary-atomizing by nozzle 11 again; The air-fuel mixture valve 15 that effect after the atomizing is more simple is compared and has been improved nearly order of magnitude, can reach 5 μ m through the diesel oil drop group particle diameter after twice atomizing, has guaranteed lighting fast of diesel oil when initial.
The utility model is sneaked into air in the diesel oil by air-fuel mixture valve 15, realizes once air-supply; Carry out secondary blast by the 3 pairs of burners of fan housing with blower, improved the excess air coefficient of diesel combustion, reach clean-burning purpose; Through test determination: flame temperature can reach more than 1500 ℃.
