Below in conjunction with attached drawing 1-2, invention is further described in detail.
A kind of efficient automobile pressure-air turbine generator, including pressure-air turbine electricity generation system and air-conditioning heating
System, air-conditioning heating system are embedded in pressure-air turbine electricity generation system, and the high pressure gas to entering turbine 11 heats up,
To improve the working efficiency of 11 electricity generation system of high-pressure turbine.
In the present embodiment, pressure-air turbine electricity generation system includes sequentially connected high pressure gas holder 1, throttle valve 3, turbine 11
And generator 12, generator 12 is connected with accumulator 13, after high pressure gas is exported out of high pressure gas holder 1, into turbine 11
Interior driving turbine 11 rotates, and the kinetic energy of high pressure gas is converted to the kinetic energy of turbine 11, the shaft of turbine 11 and turning for generator 12
Axis is connected, and then generator 12 is driven to generate electricity.
(the throttling in pressure-air turbine electricity generation system between high pressure gas holder 1 and turbine 11 is arranged in air-conditioning heating system

There are thermoconverter 22, compressor 21, blowing-type heat dump 23 and throttle valve 3.Wherein, thermoconverter 22 is arranged in high pressure gas holder
On pipeline between 1 and turbine 11, when high pressure gas passes through thermoconverter 22, carries out heat with thermoconverter 22 and turn
It changes, to have the function that heating high-pressure gas body.Coolant is equipped in pipeline 2, coolant is as intermediate medium, in pipeline 2
It circulates, flow direction of the coolant in pipeline 2 is：Thermoconverter 22- throttle valve 3- blowing-type heat dump 23- compressors 21,
Air-conditioning heating system realizes the transmission of heat by the heating to coolant.Because of blowing-type heat absorber 23 and compressor
Coolant between 21 is cryogenic gaseous, and therefore, compressor 21 is air compressor 21 in the present embodiment.
Specific heating process is as follows, and the coolant between blowing-type heat absorber 23 and air compressor 21 is low temperature gas
State is compressed after air compressor 21 sucks coolant, and air compressor 21 does work to coolant, compressed cold
But agent temperature and pressure rises, and coolant at this time is high-temperature gas；Heat is then entered by the air inlet of thermoconverter 22
It in converter 22, is condensed in thermoconverter 22, in a large amount of heat exchange to pressure-air, during condensed coolant becomes
Warm high-pressure liquid；By the decompression of throttle valve 3, coolant becomes low-temp low-pressure mist；The coolant of subsequent low-temp low-pressure mist
It absorbs heat and evaporates in absorbing heat gas into blowing-type, and then become low-temp low-pressure gaseous state, preparation reenters in air compressor 21, complete
It is recycled at one.
High pressure gas passes through the heating of air-conditioning heating system and then enters in turbine 11, and since temperature is got higher, flow adds
Soon, according to conservation of energy principle, energy quantitative change that high pressure gas is brought is more, the temperature of the high pressure air lift of discharge again with original phase
Together, therefore the generated output of generator 12 has obtained significant raising.To improve the independence of whole system, air compressor 21
It is powered using accumulator 13, does not need external additional power supply.

Solenoid valve 41, the interior flow sensor 5 for being equipped with control solenoid valve 41 and opening and closing of escape pipe 112, when flow sensor 5 detects outlet
When high-pressure gas flow is more than certain numerical value in pipe 112, just opens control solenoid valve 41 and open, only when 12 power of generator is larger
When, it just radiates to generator 12, avoids causing 12 surface temperature of generator too low, cause unnecessary energy loss.
The course of work is summarized：When high pressure gas passes through thermoconverter 22, high pressure gas temperature increases, and flow velocity adds
Soon, it then enters back into turbine 11, driving turbine 11 drives the shaft rotation of generator 12, then generator 12 is driven to generate electricity；
Air compressor 21 drives coolant cycle in pipeline 2, to provide heat in thermoconverter 22.
