Turbo-expander in the system and compressor are directly formed as a whole.
The energy recovery heat exchanger is that wind energy reclaims the combination that heat exchanger or fluid heat exchanger or wind energy reclaim heat exchanger and fluid heat exchanger.
This low-temperature liquefied energy recovery power supply system; Replenishing pipeline by circulation liquefaction medium heat exchanger, compressor, reduction valve, flash drum, liquid booster pump, fluid energy recovery heat exchanger, turbo-expander and their medium pipeline of connection and medium solution forms; The whole system structure is very simple; Therefore be convenient to install, floor space is also very little, uses easily; Provide the fluid of energy to get into the energy recovery heat exchanger among the present invention; Low boiling point working medium gets into turbo-expander through energy recovery heat exchanger heating back; The exhaust steam that the turbo-expander of low-temperature liquefied energy recovery power supply system is discharged directly gets into the heat exchanger of exhaust steam energy-recuperation system, and the liquid of carrying with liquid booster pump carries out heat exchange in heat exchanger, progressively become cryogenic gas; After boosting, the process compressor gets into reduction valve; A part of flash distillation is a liquid in flash drum, and another part machine of being compressed is inhaled back compression chamber and continued compression, also gets into compressor by heat exchanger through the cryogenic gas of discharging from turbo-expander of cryogenic liquide cooling simultaneously; And be pressurized, be collapsed into cryogenic gas and get into reduction valve with certain pressure at this; The flash distillation that circulates liquefaction is constantly supplied low-temperature liquefaction liquid and is given the liquid suction booster, realizes the continuous circulation of heat absorption vaporization → entering turbo-expander expansion acting → entering compressor compresses supercharging → flash distillation liquefaction from the energy recovery heat exchanger; Reach constantly and absorb energy, externally the purpose of acting from low temperature environment or cryogen.
Therefore this system can be with the gas that contains in the water of atmosphere, rivers,lakes and seas and various industrial process produces, the tow taste heat recycling in the flow body; Be converted into useful kinetic energy; For various processes provide power, as: can be used as the power of automobile power, train power, wheel ship power, industrial processes, the power of driving generator ....Simultaneously, can be the various spaces of cooling that need provides the equipment of chilled water, needs cooling cooling medium to be provided, for various cryogenic freezing processes the low temperature cold to be provided ....This has not only reduced environmental pollution, to cold space of need and medium cold is provided, and has saved the energy, can fundamentally reduce energy cost, solve energy crisis.
From this system of theory analysis is reasonably, and the Kano of the second law of thermodynamics is explained and told us: can not absorb heat from single source, make it all to be converted into merit and the heat engine that do not stay other any variations.
Thermomechanics also has definition to perpetuum mobile of the second kind: heat absorption constantly obtains mechanical work in ambient air or the seawater, and this single source power engine of acting down is called perpetuum mobile of the second kind.Though it does not violate the first law of thermodynamics and energy conservation, but run counter to the second law of thermodynamics, the second law of thermodynamics also can be expressed as: perpetuum mobile of the second kind is non-existent.
" cycle engine that only cools off a thermal source is unsuccessful ", " spontaneous process is irreversible ", " in irreversible adiabatic process, entropy increases, but can not reduce ".Above-mentioned theory is correct.Therefore adopt the low-temperature liquefaction technology, create low temperature environment, under the relatively low ambient temperature and under the medium temperature; Obtain cryogenic liquide through flash distillation; The cryogenic liquide of selecting possesses the rerum natura of low-temperature vaporization; Through sending into heat exchanger after the compression pump supercharging, the atmosphere and the heat in other fluid that absorb normal temperature or lower temperature are vaporizated into temperature and the higher relatively steam of pressure, promote the turbo-expander acting; The cold that utilizes the different transfer of heat principle that cryogenic liquide evaporation is produced simultaneously is applied to the higher relatively cryogen of temperature that condensation is discharged from turbo-expander again, and with sending into flash distillation after the compressor compresses behind its greenhouse cooling, circulation obtains cryogenic liquide.Just can realize: absorb heat from low-temperature heat source, make it all to be converted into merit and the heat engine that do not stay other any variations.Such system is feasible; It does not run counter to the law of thermodynamics; With the wind energy power generating system is example: when having cooled off two thermals source: 1. 2. exhaust steam of air (helium of discharging from turbine engine, nitrogen, carbon dioxide gas etc.), and also these processes all are enforceable.Selected under very environmental protection, the low temperature thermal performance compressed media preferably again in the system: helium, nitrogen, carbon dioxide etc., can be from low-temperature heat source heat removal.
Through this invention; Can draw: system itself is as creating the relatively low environment of temperature; Realize the two alternate mutual conversions of circulatory mediator vapour-liquid; This system just can be from the higher relatively thermal source of temperature heat removal, such system just can realize making it all to be converted into from the low-temperature heat source heat absorption heat engine of merit.
