Exhaust waste heat generation device, belongs to gas turbine technology application.
Background technology
Along with the raising of living standards of the people, sales volume and the recoverable amount of automobile are increasing, and current China sale of automobile amount is
Having reached annual 19000000, motor vehicles for civilian use recoverable amount has reached 110,000,000.Energy source of car consumes at total energy
Ratio shared in consumption is more and more higher, and vehicle energy saving problem increasingly receives publicity, and energy-conservation has become as world today's vapour
One of theme of car industrial development.
From the point of view of the Thermal Balance Test result of electromotor used by current automobile, the power for power output the most only accounts for fuel oil
The 30%-45% (diesel engine) or 20%-30% (gasoline engine) of burning total amount of heat.Account for the energy that waste heat form is discharged outside car
The 55%-70% (diesel engine) or 80%-70% (gasoline engine) of burning gross energy, mainly includes the heat that circulating cooling liquid is taken away
The heat that amount and vehicle exhaust are taken away.At present, the energy discharged outside car with waste heat form accounts for the 70% of gasoline combustion gross energy
(gasoline engine), is mainly made up of two large divisions, and a part is from the giving up by emission by exhaust pipe of electromotor in driving process
Gas heat, belongs to middle temperature waste heat (350-400 DEG C, 40%)；Another part passes through cold from automobile engine in driving process
But the heat that liquid disperses at engine radiator, belongs to low temperature exhaust heat (80-90 DEG C, 30%).
Can be seen that the heat that vehicle engine exhaust gas is taken away has from above-mentioned data and bigger utilize space, need further
Business development and utilization.The most how to improve the energy use efficiency of automobile, the effective heat extraction recycling automobile, be
Realize vehicle energy saving, reduce the effective way that energy source of car consumes.Along with developing rapidly of Domestic Automotive Industry, improve vapour
Car fuel effective rate of utilization and minimizing environmental pollution have prior meaning in China.
It is organic bright that Chinese patent 201110318411.1,201210116850.9,201320687768.1 etc. provides employing

Provide and use the even device reclaiming residual heat of tail gas of automobile of thermo-electric generation, its advantage be system run simple, without running device,
It there is problems of the inefficient of waste heat recovery, and conversion efficiency of thermoelectric is usually no more than 5%.
Chinese patent 201420741477.0,201420486201.2 etc. provides employing steam Rankine cycle and reclaims car tail
The device of gas waste heat, its advantage be technology maturation, waste heat recovery efficiency higher, it there is problems of waste heat recovery system
Unite complex, run control require higher, thermal inertia is big.
Chinese patent 201420684088.9 provides a kind of vehicle exhaust turbogenerator, and its advantage is simple in construction, accounts for
Little with space, its tail gas pressure that there is problems of automobile engine discharge is the highest, and conversion efficiency of thermoelectric is relatively low, because of
There is the space optimized further in this.
Chinese patent 201320854012.1 provides a kind of Kano--open Bretton hybrid power generation equipment, uses
The heat that fuel produces, heats the air after compressor compresses, and drags gas turbine expansion work, and its characteristic is to pass through
The pressure design optimized and appropriate heating-up temperature, be not provided with regenerator in cyclic process so that open Boulez pauses circulation
The temperature of emission is close to the air themperature of environment, thus effectively increases the output of merit, for substituting traditional combustion
Gas turbine cycle and Boulez pause circulation, and it is high, the most such as that it there is problems of the design of regenerator, manufacture, service requirement
What expands its range of application is worth research.
The circulation of external combustion gas turbine grows up on the basis of gas-turbine with regenerator circulates, its structure and backheat
Loop structure is similar.The distinguishing feature of this circulation is: achieves the indirect heating of combustion gas turbine, makes combustion gas without whirlpool
Turbine, it is to avoid the dirt in fuel is blended in flue gas after burning, and then the damage that causes turbine.Therefore
How to expand its range of application and be worth research.
The most how to solve the problem that existing tail gas of the car generation technology exists, set up the power generation mode that efficiency is higher, safe,
The heat energy utilization making fuel combustion produce is more reasonable, effectively reduces the discharge of greenhouse gases, becomes the difficulty of this area research
Point.
