Brief description of the drawings
The drawings below of the utility model embodiment is used to understand this practicality in this as a part of the present utility model
It is new.Shown in the drawings of embodiment of the present utility model and its description, for explaining principle of the present utility model.In accompanying drawing
In,
Fig. 1 is the schematic diagram according to the power turbine TRT of a preferred embodiment of the present utility model.
Embodiment
In the following description, a large amount of concrete details are given more thoroughly to manage the utility model to provide
Solution.It will be apparent, however, to one skilled in the art that the utility model embodiment can be without one or more
These individual details and be carried out.In other examples, in order to avoid obscuring with the utility model embodiment, for
Some technical characteristics well known in the art are not described.
In order to thoroughly understand the utility model embodiment, detailed structure will be proposed in following description.Obviously, originally
The execution of utility model embodiment is not limited to the specific details that those skilled in the art is familiar with.
Fig. 1 schematically illustrates the power turbine TRT according to a preferred embodiment of the present utility model
100 operation principle.Such as figure, it can be seen that, power turbine TRT 100 is set along in engine with turbocharger 200
Exhaust end.Wherein, the big portion that turbocharger 200 is discharged using engine (by marine engine in the utility model)
Exhaust is divided to promote the air inlet of engine.Specifically, turbocharger 200 includes the turbine and booster being coaxially disposed, and starts
The exhaust that machine is discharged causes turbine rotation, and turbine drives booster operating so as to improve the air inflow of engine, in the technology
Appearance is well known to those skilled in the art, and 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.
Power turbine TRT 100 of the present utility model, it can solve the problem that existing according to power turbine generating set
Existing technological difficulties during with engine, can solve exhaust energy distribution, generating quality control, drive connection ask
Topic, the matching adaptability of power turbine TRT 100 and engine exhaust system is greatly improved, ensures that engine is different negative
The generating quality of power turbine TRT 100 in the case of lotus, varying duty and exhaust fluctuation.
