The parts composition of apparatus of the present invention mainly contains: gas inlet casing 1, nozzle ring 2, power turbine 3, turbine case 4, rotor shaft 5, mechanical power take-off 6, bearing 7, staor winding 8, stator iron core 9, magnetic pole 10, magnetic pole winding 11, diode 12, brush 13, regulator 14, storage battery 15, slip ring 16, load 17, exhaust gas by-pass valve 18, turbine exhaust pipe 19 etc.Rotor shaft 5 and power turbine 3, mechanical power take-off 6 and magnetic pole 10 supporting installations are configured to the complete machine main body, threephase stator winding 8 is distributed in the stator slot according to certain rules, alternate each other 120 ° of electrical angles, cooperatings such as nozzle ring 2, staor winding 8, stator iron core 9, magnetic pole 10, magnetic pole winding 11, diode 12, brush 13, regulator 14, storage battery 15, slip ring 16, load 17, exhaust gas by-pass valve 18, turbine exhaust pipe 19 realize that exhaust gas pressure can be with energy recovery and directly to electric energy and mechanical energy conversion.Its working procedure is as follows:
The high-temp waste gas with certain pressure that internal-combustion engine is discharged enters nozzle ring 2 through gas inlet casing 1, turbine case 4, because the aisle spare of nozzle ring 2 is diminished gradually by the outlet that enters the mouth, thereby descend rapidly and speed improves rapidly through the exhaust gas pressure of nozzle ring 2 and temperature.This off-gas flows at a high speed by nozzle ring 2 ejections, impacts power turbine 3 by certain direction, makes power turbine 3 high speed rotating, and the pressure of waste gas, temperature and speed are high more, and power turbine 3 rotating speeds are also fast more.Waste gas by power turbine 3 enters atmosphere at last by turbine exhaust pipe 19.Simultaneously, by excitation, make a pawl utmost point form the N utmost point when the magnetic field winding is connected direct current, another piece pawl utmost point forms the S utmost point.The magnetic line of force is sent by the N utmost point on the rotor shaft 3, passes air clearance very little between rotor and stator and enters stator iron core 9, gets back to the adjacent S utmost point through the air clearance again at last, and constitutes magnetic loop by yoke.Turbine 3 rotations drive rotor shaft 5 rotations that are solidly installed with it, rotor shaft 5 rotations drive the externally output work done of mechanical power take-off 6 that is solidly installed with it on the one hand, on the other hand, because staor winding 8 cutting magnetic lines, frequency is identical, amplitude equates, the simple alternating current electromotive force of 120 ° of electrical angles of phase phase difference so produce in threephase stator winding 8, becomes direct current energy output after the rectification circuit rectification that silicon diode 12 is formed.
In addition, staor winding 8 and mechanical power take-off 6 external output powers are directly proportional with the rotating speed of rotor shaft 5, and the exhaust energy that rotor shaft 5 rotating speeds and engine speed and load are promptly discharged is relevant, exhaust energy is big more, the turbine that causes is that the rotor shaft rotating speed is high more, thereby staor winding 8 and mechanical power take-off 6 external output powers are big more, external power is exported excessive when not required for avoiding this device, this device is provided with exhaust gas by-pass valve 18, promptly when not needing too much power output, exhaust gas by-pass valve 18 is opened, and bleeds off a part of waste gas.
Power turbine 3 can be radial-flow type and also can be axial flow, because radial turbine efficient height, volume are little, simple in structure, so the radial-flow type power turbine is preferentially selected in recommendation for use.
This device electric energy and mechanical energy can be exported simultaneously, can also independently export by a kind of form of energy, during independent output, corresponding load or parts are removed get final product, when exporting as only being used as electric energy, mechanical load are removed or mechanical power take-off 6 removed getting final product.
Embodiment 1: internal-combustion engine constant pressure type exhaust energy is recycled power supply and accessory power supply system
Each cylinder gas exhaust manifold 21 of internal-combustion engine is at first inserted an exhaust manifold 22 that volume is bigger, with the waste gas voltage stabilizing of confluxing, insert gas inlet casing 1 on the utility model devices 20 by exhaust manifold 22 then and promptly constitute the constant pressure type exhaust energy and recycle power supply and accessory power supply system.Because exhaust manifold 22 plays the effect of pressure stabilizer, so, entering before the power turbine 3, the exhaust gas pressure pulsation is less, has more stable pressure.This system can only utilize the expansion work of waste gas in power turbine, and exhaust energy all can not be utilized.
Embodiment 2: internal-combustion engine pulsed exhaust energy is recycled power supply and accessory power supply system
Each cylinder gas exhaust manifold 21 of internal-combustion engine is made branch's pattern, and the gas inlet casing 1 that each branch row tracheae 23 inserts respectively on this device 20 promptly constitutes pulsed exhaust energy recycling power supply and accessory power supply system.This system dynamic turbine 3 has a plurality of waste gas inlets.
Be simplified structure, relevant each cylinder can insert same outlet pipe, is communicated with gas inlet casing 1 then.For quartastroke engine, exhauxt valve opens continues 240 ° of crank angles approximately to closing, there is the valve overlap problem in the exhaust end of a period stage, for utilizing exhaust energy better, must make the exhaust pulses ripple that is kept perfectly in the gas exhaust manifold, therefore when organizing outlet pipe branch, must make igniting differ each above cylinder outlet pipe of 240 ° of crank angles at interval is connected together, but an outlet pipe can not be connected with the cylinder more than three cylinders, otherwise this system and the utility model embodiment's 1 constant-voltage system does not have too big difference.When the cylinder of internal combustion engine number is 3 multiple, quartastroke engine is the firing interval angle that three cylinders of 240 ° of crank angles are linked to be an exhaust branch road and can form a desirable pulsed system (as Fig. 3), but when not being three multiple for number of cylinders (as 4,5,8,10 cylinders), do not disturb for making between the cylinder exhaust, the firing interval angle can only be linked to be an exhaust branch road greater than each cylinders of 240 ° of crank angles, but, because exhaust is at interval greater than exhaust perdurabgility in branch road, just discontinuous air feed or intermittent gas supply problem have been produced to power turbine 3, intermittent gas supply increases the exhaust-gas flow loss, reduce available energy, reduce the conversion efficiency of power turbine.For overcoming these problems, can on number of cylinders is the internal-combustion engine of non-triple, pulse converter 24 be installed.Pulse converter 24 imports are connected with branch row tracheae 23, pipeline area is shrunk to nozzle-like, gas is quickened, the outlet port forms mixing section, the waste gas of discharging from branch row tracheae 23 enters pulse converter 24, enter gas inlet casing 1 after the mixing, so just can guarantee continuous air feed to power turbine.
