Description
Technical field
The present invention relates to a kind of engine exhaust system, more specifically to one, there is waste thermal energy flexibility retracting device
Rankine cycle arrangement system, belong to Rankine cycle technical field.
Background technology
Rankine cycle refers to a kind of Ideal Cycle process for steaming device power cycle, is mainly used in remaining at home
Hot power field.
Traditional Rankine cycle system arrangement form sees Fig. 2, within the system, and the highly pressurised liquid flowed out from working medium pump 1
Working medium carries out heat exchange by heat exchanger 2, thus the state from subcooled liquid to superheated steam that realizes changes；Then cross hot working fluid to steam
Vapour enters decompressor 3, and power pressure is become condensing pressure (low pressure) from the bulbs of pressure (high pressure), completes expansion work during this period and arrives
The conversion of mechanical power is also exported electromotor 4 by the outfan of pinion unit 6；The steam that decompressor 3 is discharged is in condenser 5
Becoming supercooled state from superheat state, the working medium of condensing state is pressurizeed by working medium pump 1 and is entered heat exchanger 2, thus completes this work
The thermodynamic cycle of matter.But, in this traditional willing blood circulation arrangement form, working medium completes to expand in decompressor 3, expands
Working medium expansion work is converted to mechanical power by machine 3, and is exported electromotor 4 bent axle by the outfan of pinion unit 6.Gear drive
Being 6 for positive drive mechanism, directly realize slowing down with gear and power transmits, impact is relatively big, therefore can cause this system stability
Property is poor, and pinion unit 6 is also had bigger damage；Meanwhile, once electromotor 3 rotating speed is more than the rotating speed of pinion unit 6, meeting
Cause electromotor towing astern rankine cycle system.
Summary of the invention
The present invention is directed to causing this system stability poor or causing of existing Rankine cycle system arrangement form existence
The problems such as electromotor towing astern rankine cycle, it is provided that a kind of Rankine cycle arrangement system with waste thermal energy flexibility retracting device.
For achieving the above object, the technical solution of the present invention is: a kind of have the bright of waste thermal energy flexibility retracting device
Agreeing cycle arrangement system, including working medium pump, heat exchanger, decompressor, condenser and pinion unit, described pinion unit is defeated
Go out end tooth wheel to be meshed with engine crankshaft gear, between described decompressor and pinion unit, be provided with fluid coupling,
The output gear of described decompressor is meshed with the input gear of fluid coupling.
Described fluid coupling rear end is provided with freewheel clutch, the output gear of fluid coupling rear end with surmount from
The gear of clutch front end is meshed, and the described gear of freewheel clutch rear end is meshed with the input end gear of pinion unit.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is provided with fluid coupling between decompressor and pinion unit, the output gear of decompressor and fluid power coupling
The input gear of clutch is meshed；The mechanical power that expansion work is changed can be reclaimed by fluid coupling flexibility and pass to send out
Motivation bent axle, thus improve the service life of equipment, reduce the abrasion of equipment, improve the stability of pinion unit,
Achieve flexible recovery Rankine cycle waste heat energy regenerating, improve engine output, improve economy.
2, in the present invention, fluid coupling rear end is provided with freewheel clutch, and freewheel clutch is prevented from engine crankshaft
Towing astern Rankine cycle system, thus ensure that the organic efficiency of energy.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is traditional Rankine cycle system arrangement form figure.
Accompanying drawing illustrates, working medium pump 1, heat exchanger 2, decompressor 3, electromotor 4, condenser 5, pinion unit 6, coupling fluid-structure
Device 7, freewheel clutch 8.
Detailed description of the invention
Illustrate that the present invention is described in further detail with detailed description of the invention below in conjunction with accompanying drawing.
See Fig. 1, a kind of Rankine cycle arrangement system with waste thermal energy flexibility retracting device, relate to waste thermal energy and reclaim,
Including working medium pump 1, heat exchanger 2, decompressor 3, condenser 5 and pinion unit 6.Described pinion unit 6 gear of output end
It is connected with electromotor 4 crankshaft toothed wheel, between described decompressor 3 and pinion unit 6, is provided with fluid coupling 7, described
The output gear of decompressor 3 is meshed with the input gear of fluid coupling 7.This decompressor 3 form does not limits, and can be to open up frequency
Formula, vortex, piston type, screw etc..
Seeing Fig. 1, further, described fluid coupling 7 rear end is provided with freewheel clutch 8, after fluid coupling 7
The output gear of end is meshed with the gear of freewheel clutch 8 front end；The gear of described freewheel clutch 8 rear end and gear drive
Be 6 input end gear be meshed.
Seeing Fig. 1, during work, this Rankine cycle system carries out heat exchange, cycle fluid by working medium and engine exhaust heat
Heat absorption expands, and promotes decompressor 3 to rotate, and decompressor 3 is connected by gear with fluid coupling 7, transmits power；Fluid coupling
7 realize flexibility transmission, impart power to freewheel clutch 8.Freewheel clutch 8 unidirectional delivery moment of torsion, it reversely skids can
Prevent electromotor 4 bent axle towing astern Rankine cycle system；Pinion unit 6 realizes decelerating effect, makes the energy that rankine cycle reclaims
Pass to electromotor 4 with suitable speed ratio and impart power to electromotor 4.
Seeing Fig. 1, the present invention is by the decompressor 3 in traditional Rankine cycle system arrangement form and pinion unit
Add fluid coupling 7 between 6, and freewheel clutch 8 is set in fluid coupling 7 rear end, so that expansion work conversion
Mechanical power can pass to electromotor 4 bent axle by flexible recovery of fluid coupling 7, and flexible transmission decreases impact, reduces
Equipment attrition, it is achieved that flexible recovery Rankine cycle waste heat energy regenerating.Meanwhile, freewheel clutch 8 prevents electromotor 4 bent axle towing astern
This Rankine cycle system, it is ensured that the organic efficiency of energy.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, said structure all should be considered as belonging to
