Brief description of the drawings
The drawings below of embodiment of the present invention is used to understand the present invention in this as the part of the present invention.Show in accompanying drawing
Embodiments of the present invention and its description are gone out, for explaining the principle of the present invention.In the accompanying drawings,
Fig. 1 is the schematic diagram according to the power turbine TRT of a preferred embodiment of the present invention.
Embodiment
In the following description, a large amount of concrete details are given to provide more thorough understanding of the invention.So
And it will be apparent to one skilled in the art that embodiment of the present invention can be without one or more of these thin
Save and be carried out.In other examples, in order to avoid obscuring with embodiment of the present invention, for well known in the art
Some technical characteristics are not described.
In order to thoroughly understand embodiment of the present invention, detailed structure will be proposed in following description.Obviously, it is of the invention
The execution of embodiment is not limited to the specific details that those skilled in the art is familiar with.
Fig. 1 is schematically illustrated according to the power turbine TRT 100 of a preferred embodiment of the present invention
Operation principle.Such as figure, it can be seen that, power turbine TRT 100 is set along the row in engine with turbocharger 200
Gas end.Wherein, most of exhaust that turbocharger 200 is discharged using engine (in the present invention by marine engine) come
Promote the air inlet of engine.Specifically, turbocharger 200 includes the turbine and booster being coaxially disposed, and engine is discharged
Exhaust cause turbine rotation, turbine drives booster operating, and so as to improve the air inflow of engine, the technology contents are ability
Known to the technical staff in domain, it will not be repeated here.
It is excessive in the capacity that engine is arranged, when also having remaining after supplying turbocharger 200, remaining exhaust
Power turbine TRT 100 can be supplied to, power turbine TRT 100 can use the exhaust of engine to be sent out
Electricity.
Power turbine TRT 100 includes power turbine 1 and generator 3.Power turbine 1 and turbocharger 200 are simultaneously
Connection is arranged between the exhaust end of engine and air.When power turbine TRT 100 works, the exhaust of engine can
Supply can drive power turbine 1 to rotate to power turbine 1, exhaust, and the energy conversion of exhaust is for mechanical energy.Further, move
Power turbine 1 can drive the generator 3 being connected with power turbine 1 to rotate operation so as to generate electricity by rotating, and mechanical energy is further
Electric energy is converted into, so just realizes the function that power turbine TRT 100 is generated electricity using the exhaust of engine.
And engine possibly can not ensure that exhaust is uniform, in order that obtaining the run evenly of power turbine 1 so as to ensure generator 3
Can steadily it generate electricity, power turbine TRT 100 is additionally provided with adjusting part, and adjusting part, which is used to adjust, enters power turbine
The capacity of 1 exhaust.Preferably, adjusting part includes the first regulating valve 5, the second regulating valve 6 and control unit 8, and control is single
Member 8 is used to control the first regulating valve 5 and the second regulating valve 6.Wherein, the first regulating valve 5 is arranged on the exhaust end of engine with moving
Between power turbine 1, the second regulating valve 6 is arranged between the first regulating valve 5 and air.
Generally, engine is provided with Design cooling load (i.e. gauge load), when engine is run with Design cooling load, engine
The exhaust arranged just meets that (i.e. Design cooling load is and power whirlpool for needs that turbocharger 200 and power turbine 1 run well
The load that wheel 1 matches), now control unit 8 controls the first regulating valve 5 to keep standard aperture, the second regulating valve 6 to close.When
When the operating load of engine is less than Design cooling load, control operation the first regulating valve 5 of control unit 8 and the second regulating valve 6 so that
The aperture of first regulating valve 5 is less than standard aperture, and the second regulating valve 6 is closed.Born when the operating load of engine slightly above designs
During lotus, control operation the first regulating valve 5 of control unit 8 and the second regulating valve 6 so that the aperture of the first regulating valve 5 is more than standard
Aperture, the second regulating valve 6 are still closed, and when operating load is apparently higher than Design cooling load, adjusted in the control of control unit 8 first
While the aperture of section valve 5 is more than standard aperture, it also can correspondingly control and open the second regulating valve 6 so that unnecessary exhaust is straight
Connected the second regulating valve 6 and be discharged outside to air, that is to say, that by the second regulating valve 6 be expelled to the exhaust of air without
Cross power turbine 1.
By the adjustment effect of adjusting part, even if the capacity of engine is uneven, power turbine hair is not interfered with yet
The even running of electric installation 100, in the case where the capacity of engine is uneven, the generating of power turbine TRT 100
Machine 3 also can steadily generate electricity, and be effectively guaranteed generating quality.
Preferably, generator 3 is connected by gear-box 2 with power turbine 1, between generator 3 and gear-box 2, gear-box 2
It is connected between power turbine 1 by shaft coupling 7 and flange.These annexations can ensure that power turbine 1 effectively drives hair
Motor 3 operates, so as to ensure that generator 3 effectively generates electricity.
In order to further such that the generation frequency of generator 3 stabilization, between generator 3 and power network, is additionally provided with frequency converter
4.Frequency converter 4 can compensate for the fluctuation of the generation frequency brought due to the fluctuation of speed of power turbine 1, and generator 3 is sent out
Electric frequency further adjusted so that it is more stable, so as to further ensure that generating quality.
The power turbine TRT 100 of the present invention, it can solve the problem that existing matched according to power turbine generating set is sent out
Existing technological difficulties during motivation, can solve the problems, such as exhaust energy distribution, generating quality control, drive connection, can
The matching adaptability of power turbine TRT 100 and engine exhaust system is greatly improved, ensures engine different load, become
The generating quality of power turbine TRT 100 in the case of load and exhaust fluctuation.
