The utility model has the advantages that: the utility model relates to a kind of recycle scheme making liquefied natural gas Multi-class propagation aboard ship, solve the waste of LNG cold energy and the waste problem of dual-fuel diesel exhaust temperature that there is environmental protection, the feature such as energy-conservation, efficient.Its design plan is the principle based on Rankine cycle, and utilize principle to realize its object with energy cycle multistage, cabin cooling decreases the use of air-conditioning, environmental protection, energy-conservation, economical, should have the wide market space.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of LNG Multi-class propagation system on the utility model ship;
In figure: 1, dual-fuel diesel 2, natural fuels turbine expansion electrical generator 3, first heat exchanger 4, second heat exchanger 5, LNG storage tank 6, cabin evaporator 7, the 3rd heat exchanger 8, methane turbine expansion electrical generator 9, sea water pump.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
LNG Multi-class propagation system on ship, comprise dual-fuel diesel 1, natural fuels turbine expansion electrical generator 2, first heat exchanger 3, second heat exchanger 4, LNG storage tank 5, cabin evaporator 6, the 3rd heat exchanger 7, methane turbine expansion electrical generator 8 and sea water pump 9, described dual-fuel diesel 1 connects natural fuels turbo-expander generating the 2, first heat exchanger 3, second heat exchanger 4 and LNG storage tank 5 successively by pipeline, realizes the utilization of cold energy; Methane turbine expansion electrical generator 8 connects the second heat exchanger 4 and the 3rd heat exchanger 7 successively by pipeline, and forms closed cycle pipeline, connects sea water pump 9 and cabin evaporator 6 on the left of the 3rd heat exchanger 7.
The offgas duct of described dual-fuel diesel 1 accesses the first heat exchanger 3, realizes the effective utilization to using waste heat from tail gas.
Described sea water pump 9 accesses in seawater, for extracting seawater.
Using method of the present utility model: LNG cold generating flow process, adopting with propane is the Rankine hybrid cycle of working medium and the direct expansion turbine of natural fuels.Propane liquid absorption seawater heat gasifies, and high pressure steam drives methane turbine expansion electrical generator 8, and cooled seawater is used for accessing cabin evaporator 6 and lowers the temperature to cabin.Subsequently in propane second heat exchanger 4 heat release by LNG condensation.Meanwhile, high pressure LNG endothermic gasification, becomes high pressure steam, drives natural fuels turbine expansion electrical generator 2 to generate electricity.By the fuelled with natural gas gasified for boats and ships provide power, using waste heat from tail gas enters the first heat exchanger 3 conversely again to the heated by natural gas gasified, allow its high pressure steam be generated electricity by natural fuels turbine, natural fuels afterwards enters dual-fuel diesel again for boats and ships provides power.Realize the recycle of the energy.
