Description
Technical field
The present invention relates to one and be applied to special vehicle (large-scale military construction vehicle, large-scale military truck, large-scale troop-carrying coach etc.) under severe cold condition, the ordinary diesel oil gasification, and combustion warmer of warming-up work.
Background technology
At present, under severe cold condition, special vehicle generally adopts independent preheating device, carries out pre-heating, improve the startability of vehicle, increase the service life engine body, the anti-icing fluid circulatory system, lubrication wet goods.
By the analysis to existing same device service condition, find that existing same device ubiquity following three aspects not enough: one is that the atomization quality of ordinary diesel oil affects larger by extraneous factor.When temperature is lower, the mobility of ordinary diesel oil and volatility all can significantly reduce, and under same pressure, atomization quality is not good; When after atomizer generation mechanical wear, it will change the restraint performance of ordinary diesel oil, and atomizer (atomizing) cone shape, atomizing particle diameter are all unfavorable for burning.
Two is that plant failure rate is higher.The igniting of overwhelming majority heating apparatus adopts electrothermal method, the electric energy that not only a large amount of consumption is limited, heating wire fusing also often occurs, sinters, cause lighting rate low; The precision pair of mechanical plunger-piston oil pump requires higher to oil quality, and very easily corrosion occurs, and causes charge oil pressure to decline, and time serious, nozzle can not realize atomization.
Three is that exchange heat rate is not high.Heat exchanger power is large, and volume is little, if heat change body structure is unreasonable, the sensible heat that ordinary diesel oil burning produces then can not efficiently exchange with anti-icing fluid in time, and heat is discharged with flue gas, causes waste.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of sufficient combustion, the special vehicle equipment ordinary diesel oil gasification, and combustion warmer of reliable operation.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes work assembly and supply assembly, described supply assembly comprises air blast, water pump, oil pump and has the air compressor machine of air accumulator, work assembly described in its structural feature comprises the water tank that same water pump is connected, be provided with heat exchanger in water tank, heat exchanger is provided with burner; Described burner comprises the atomizer with igniter, and atomizer is connected with the air inlet pipe of air accumulator with the oil inlet pipe of oil pump; Described oil inlet pipe is provided with dish type economizer bank corresponding to atomizer.
Beneficial effect of the present invention:
1, after burner igniting of the present invention, form stable fired state, 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 rises to 300 ~ 365 DEG C, diesel oil reaches gasification condition, and burner proceeds to the gasification, and combustion stage automatically; Sufficient combustion of the present invention; The thermal efficiency is high, to water tank Fast Heating, can reach the object that the short time completes warming-up.
2, spray burning phases-time of the present invention is short, only about 30s; The frayed degree of atomizer is lower, and atomizer of the present invention can need not be safeguarded for a long time, not fragile.
3, specific volume power of the present invention is large, good with existing vehicle mounting matching, and be applicable to a multiple military construction vehicle equipment, large-scale military transport vehicle, large-scale troop-carrying coach preheating need.
