The utility model discloses insert organic rankine cycle with internal -combustion engine driven refrigerator to improve organic rankine cycle generated energy.
Description
Technical field
This utility model relates to energy recycling device field, particularly relates to the system of a kind of refrigeration machine auxiliary organic Rankine bottoming cycle.
Background technology
Organic Rankine bottoming cycle (OrganicRankineCycle is called for short ORC) is the Rankine cycle with low-boiling-point organic compound as working medium, is mainly made up of heat exchanger, decompressor, condenser, pump four major part.Operation principle is that heat transferring medium absorbs heat in heat exchanger from residual heat stream, generate the steam with certain pressure and temperature, steam enters decompressor acting thus drives electromotor or other dynamic power machines, the steam discharged from decompressor condenses within the condenser, last by being pumped back to heat exchanger, the most constantly circulation is gone down.Reducing delivery temperature is to improve a kind of effective means of the Rankine cycle thermal efficiency, but the numerical value of final pressure and final temperature depends on the Temperature of Working in condenser, only is difficult to be greatly lowered by condenser.
In the place producing natural gas, combustion gas is more than needed and electric power lacks, and therefore coordinates organic Rankine bottoming cycle circulation on the basis of burning natural gas generates electricity, further with the heat energy of burning, improves generated energy.If but when needs the most emergent raising further generated energy, if additionally purchasing an internal combustion engine generating, improve cost.
Utility model content
The purpose of this utility model is to provide that a kind of cost investment is few, can meet an urgent need promotes the organic Rankine cycle power generation system of generated energy temporarily, utilize the refrigeration machine of the gas driven for carrying out natural gas liquefaction that gas field is natively configured with, the pipeline of oil-engine driven refrigeration machine is accessed in organic Rankine bottoming cycle, thus realizes short-term and promote generated energy to meet the purpose of emergent demand.
The system of a kind of refrigeration machine auxiliary organic Rankine bottoming cycle generating, its feature includes the first internal combustion engine, heat exchanger, decompressor, condenser, refrigeration machine, the second internal combustion engine, pump；The aerofluxus after generating of externally doing work of first internal combustion engine is released through heat exchanger and is discharged after heat, and the expanded machine of working medium of heat exchanger heating externally does work after generating, by condenser, the second oil-engine driven refrigeration machine be pumped back to heat exchanger.
According to one preferred embodiment of this utility model, the aerofluxus of the second internal combustion engine of the system of described refrigeration machine auxiliary organic Rankine bottoming cycle generating is discharged after heat released by heat exchanger.
This utility model compared with prior art provides the benefit that: the organic Rankine cycle power generation system cost investment of the present invention is few, lifting generated energy of can temporarily meeting an urgent need, utilize the refrigeration machine of the gas driven for carrying out natural gas liquefaction that gas field is natively configured with, the pipeline of oil-engine driven refrigeration machine is accessed in organic Rankine bottoming cycle, thus realizes short-term and promote generated energy to meet the purpose of emergent demand.In the place producing natural gas, owing to combustion gas is more than needed, electric power lacks, and can improve generated energy further with the heat energy of fuel gas buring by this utility model, reduce cost.

Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the invention provides the system of a kind of refrigeration machine auxiliary organic Rankine bottoming cycle generating, including the first internal combustion engine 1, heat exchanger 2, decompressor 3, condenser 4, refrigeration machine the 5, second internal combustion engine 6, pump 7；First internal combustion engine 1 externally do work generating after aerofluxus discharges after heat released by heat exchanger 2, heat exchanger 2 heating the expanded machine of working medium 3 externally do work generate electricity after, by condenser the 4, second internal combustion engine 6 driving refrigeration machine 5 and pump 7 return to heat exchanger 2.
The method of the refrigeration machine auxiliary organic Rankine bottoming cycle generating of system shown in Figure 1: the pipeline of the refrigeration machine 5 driven by the second internal combustion engine 6 accesses in organic Rankine bottoming cycle, condensation temperature and the condensing pressure of condenser 4 is reduced further by refrigeration machine 5, to improve the Rankine cycle thermal efficiency, it is achieved short-term is met an urgent need and promoted the purpose of generated energy.
As in figure 2 it is shown, as preferably, the aerofluxus of the second internal combustion engine 6 can also be discharged, with further with exhaust heat after heat released by heat exchanger 2, it is achieved short-term is met an urgent need and promoted the purpose of generated energy.
The method of corresponding refrigeration machine auxiliary organic Rankine bottoming cycle generating:
The pipeline of 1 refrigeration machine 5 driven by second internal combustion engine 6 accesses in organic Rankine bottoming cycle, is reduced condensation temperature and the condensing pressure of condenser 4 further by refrigeration machine 5, to improve the Rankine cycle thermal efficiency.
The aerofluxus of the second internal combustion engine 6 is introduced heat exchanger by 2 participates in organic Rankine bottoming cycle, with further with exhaust heat, it is achieved short-term is met an urgent need and promoted the purpose of generated energy.
