The tail gas of internal-combustion engine drives turbine generator
Technical field
The present invention relates to technical field of internal combustion engines, the tail gas that relates in particular to a kind of internal-combustion engine drives turbine generator.
Background technique
The energy of the tail gas of internal-combustion engine accounts for about 30% of engine thermal efficiency at present, and the energy that tail gas comprises has heat energy and kinetic energy, and for example the vehicle exhaust of 1.4 liter capacities can be exported the energy about 9.8 kilowatts when high rotating speed; The rotating speed of turbine reaches about 100,000 rpms, and the secondary speed of the big discharge capacity that has can be up to 300,000 rpms, and tail gas energy reaches 50 kilowatts even higher energy; Turbine can be a kinetic energy with 75% Conversion of energy of tail gas; Motor can be converted into electric energy with about 75% of kinetic energy again, in this case, if just can obtain the electric current about 100 peaces with 12 volts of outputs of direct current; This electric current is relevant with the discharge capacity of motor fully; The discharge capacity of motor is big more, and it is just big more that tail gas is converted into 12 volts electric current, but existing technology does not have good use tail gas; Cause the loss of energy, be difficult to reach the purpose that energy-saving and emission-reduction improve internal combustion engine thermal efficiency.
Summary of the invention
The tail gas that the purpose of this invention is to provide internal-combustion engine drives turbine generator; It can provide electricity consumption for equipment such as automobiles; Can electricity consumption driving the air-conditioning of car body or for electric energy storage device supplies charging, like this can without the engine-driving air condition compressor or to drive motor be battery charge, the power that neither consumes automobile has guaranteed that again the power of motor exports; And utilized emission power generation and power supply, finally play the purpose that energy-saving and emission-reduction improve internal combustion engine thermal efficiency.
In order to solve the existing problem of background technique, the present invention adopts following technological scheme: it comprises turbine 5 and air flue part 2, turbine speed regulating mechanism part 6 and engine section 3.
Described turbine 5 mainly comprises the cavity that turbine 5, turbine shaft, tail gas air inlet inlet 1 and tail gas outlet 4 form with air flue part 2; The diameter of tail gas air inlet inlet 1 is less than the diameter of tail gas outlet 4; Be blown into by high pressure exhaust gas inlet 1 like this, drive turbine 5 rotations, the reduction of tail gas pressure is discharged tail gas from tail gas outlet 4 then; Drive turbine shaft through this process turbine 5 and make circular movement, so just accomplished turbine shaft and driven the purpose that turbine 5 gears reach Conversion of energy.
Described turbine speed regulating mechanism part 6 is the needed speed range of rotor that convert driving generator 7 through the Conversion of energy turbine shaft process gear proportioning of turbine 5 and air flue part 2 to, reaches stable generating purpose.
Described engine section 3 is the transformation of energy through turbine speed regulating mechanism part 6, and the rotor of generator 7 has obtained the energy that rotates, and the rotor cutting magnetic line produces electric current, and through rectifier and voltage stabilizer output current, the electric current of output can be direct current or interchange.
Described generator 7 is connected with battery accumulate part 8.
The present invention can provide electricity consumption for equipment such as automobiles; Can electricity consumption drive the air-conditioning of car body or be electric energy storage device confession charging; Can be battery charge without engine-driving air condition compressor or driving motor like this; The power that neither consumes automobile has guaranteed the power output of motor again, and has utilized emission power generation and power supply, finally plays the purpose that energy-saving and emission-reduction improve internal combustion engine thermal efficiency.
