Description
Technical field
The present invention 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 ordinary diesel oil gasification combustion heater that warming-up work is used.
Background technique
At present, under the severe cold condition, special vehicle generally adopts independent Preheating unit, and engine body, the antifreeze liquid circulatory system, lubricated wet goods are heated in advance, improves the startability of vehicle, increases the service life.
By the analysis to existing same device use condition, find that existing same device ubiquity following three aspect deficiencies: the one, it is bigger that the atomization quality of ordinary diesel oil is influenced 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, not only consumes limited electric energy in a large number, and electric heating wire fusing, sintering also often take place, and causes lighting rate low; The precision pair of mechanical plunger formula oil pump is had relatively high expectations to oil quality, and very easily corrosion takes place, and causes charge oil pressure to descend, and nozzle can not be realized atomizing when serious.
The 3rd, the exchange heat rate is not high.Heat exchanger power is big, and volume is little, if the heat exchanger unreasonable structure, the sensible heat that the ordinary diesel oil burning produces then can not efficiently exchange with antifreeze liquid in time, and heat is discharged with flue gas, causes waste.
Summary of the invention
The present invention is exactly at the problems referred to above, and a kind of sufficient combustion is provided, the special vehicle equipment ordinary diesel oil gasification combustion heater of reliable operation.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technological scheme, the present invention includes the work assembly and supply with assembly, described supply assembly comprises blower, water pump, oil pump and has the air compressor of gas holder, the described work assembly of its structure outline comprises the water tank that links to each other with water pump, be provided with heat exchanger in the water tank, be provided with burner corresponding to heat exchanger; Described burner comprises the atomizer nozzle with igniter, and atomizer nozzle links to each other with the oil inlet pipe of oil pump and the suction tude of gas holder; Be provided with the dish type economizer bank corresponding to atomizer nozzle on the described oil inlet pipe.
Beneficial effect of the present invention:
1, after the burner igniting of the present invention, 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; Sufficient combustion of the present invention; Thermal efficiency height can be to the water tank rapid heating, reaches the short time to finish the purpose of warming-up.
2, time in atomization combustion stage weak point of the present invention is only about 30s; The frayed degree of atomizer nozzle is lower, and atomizer nozzle of the present invention can need not be safeguarded for a long time, and is not fragile.
3, specific volume power of the present invention is big, and is good with existing vehicle mounting matching, is fit to a multiple military construction vehicle equipment, and large-scale military transport vehicle, large-scale troop-carrying coach preheating need.
