Description

Technical fields:

[0001] This invention belongs to the field of thermodynamics and heat pump technology. Background technology:

[0002] Heat pump technology is an important means of obtaining cold / heat / steam / power and realizing the high-value utilization of energy. In practical applications, it is necessary to consider operating parameters, performance index, manufacturing cost, adaptability, as well as the characteristics of different energy sources and targeted technical means.

[0003] High-quality fuels, typically represented by natural gas, gasoline, and diesel, are high-temperature heat sources with temperatures exceeding several thousand degrees Celsius. Achieving efficient and high-value utilization of these high-quality fuels is of great significance and presents significant technical challenges.

[0004] The advantage of internal combustion engines that utilize high-quality fuels lies in the utilization of the thermal energy of the high-temperature section of the gas and the provision of power. The further issue to be addressed is how to achieve efficient utilization of the gas exhaust heat load using the simplest possible technical means.

[0005] Vapor compression heat pump technology, which operates on the principle of reverse Rankine cycle, has the advantage of being able to achieve constant-temperature heat absorption; however, meeting the demand for high-parameter heating or steam is technically challenging.

[0006] An ejector is a pressure-boosting component that effectively utilizes high-temperature heat resources. It has the advantages of simple structure, reliable operation, low investment and long service life. In addition, compared with compressors, ejectors are more adaptable to the compression of wet steam.

[0007] Based on the fundamental principles of simple and efficient use of high-quality fuels for refrigeration / heating / steam production / power, this invention presents a combined cycle heat pump system for energy and internal combustion engines that features a rational process, simple structure, multiple functions, and optimized performance index.

Detailed implementation method:

[0044] First, it should be noted that the structure and process are not repeated unless necessary, and obvious processes are not described. The invention will now be described in detail with reference to the accompanying drawings and examples.

[0045] Figure 1 The energy-carrying internal combustion engine combined cycle heat pump system shown is implemented as follows:

[0046] (1) Structurally, it mainly consists of an internal combustion engine, a compressor, a high-temperature heat exchanger, a steam generator, a second steam generator, a second compressor, an injector, a heater, a booster pump, a second booster pump, a throttle valve, an evaporator, and a second injector; externally, there is an air passage that connects to the internal combustion engine 1 via the compressor 2 and the high-temperature heat exchanger 3, and an external fuel passage that connects to the internal combustion engine 1. The internal combustion engine 1 also has a gas passage that connects to the steam generator 4 and the second steam generator 5 before connecting to the outside. The internal combustion engine 1 also has a cooling medium passage that connects to the outside. The second compressor 6 has a refrigerant vapor passage that connects to the low-pressure steam inlet of the injector 7. The steam generator 4 has a steam passage that connects to the high-pressure steam inlet of the injector 7. The injector 7 also has a medium-pressure refrigerant vapor passage that connects to the heater 8. Heater 8 also has a condensate pipeline connected to steam generator 4 via booster pump 9. Heater 8 also has a condensate pipeline connected to second steam generator 5 via second booster pump 10. Heater 8 also has a condensate pipeline connected to evaporator 12 via throttle valve 11. Second steam generator 5 has a steam channel connected to the high-pressure steam inlet of second injector 13. Evaporator 12 also has a refrigerant steam channel connected to the low-pressure steam inlet of second injector 13. Second injector 13 also has a medium-pressure refrigerant steam channel connected to second compressor 6. High-temperature heat exchanger 3 also has a high-temperature heat medium channel connected to the outside. Heater 8 also has a heated medium channel connected to the outside. Evaporator 12 also has a low-temperature heat medium channel connected to the outside. Internal combustion engine 1 connects to compressor 2 and second compressor 6 and transmits power.

[0047] (2) In terms of process, external air flows through compressor 2 to increase pressure and temperature, then flows through high-temperature heat exchanger 3 to absorb heat and increase temperature, and then enters internal combustion engine 1; external fuel enters internal combustion engine 1, and fuel and air complete a series of processes including combustion and expansion in the cylinder of internal combustion engine 1; the exhaust gas emitted by internal combustion engine 1 flows through steam generator 4 and second steam generator 5 to gradually release heat and cool down before being discharged to the outside; the cooling medium flows through the cooling cylinder liner of internal combustion engine 1 to carry away the exhaust cooling heat load; the refrigerant vapor emitted by second compressor 6 is supplied to injector 7, and steam generation... The steam generated by the second compressor 4 enters the ejector 7 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle, where its pressure is reduced and its speed is increased, forming a low-pressure system. The refrigerant steam discharged from the second compressor 6 is drawn into the low-pressure zone of the ejector 7. After the two steam streams mix, they flow through the diffuser, where their speed is reduced and their pressure is increased, forming medium-pressure refrigerant steam, which is then supplied to the heater 8. The refrigerant steam enters the heater 8, releases heat, and condenses. It then splits into three streams: the first stream flows through the booster pump 9 for pressurization and enters the steam generator 4 to absorb heat and vaporize; the second stream flows through the second booster pump 10 for pressurization and enters the second steam generator 5 to absorb heat. The vaporized gas flows through the third path, which is depressurized and cooled by the throttle valve 11 before entering the evaporator 12 to absorb heat and vaporize. The steam generated by the second steam generator 5 enters the second injector 13 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle to reduce pressure and increase speed, forming a low-pressure system. The refrigerant steam generated by the evaporator 12 is drawn into the low-pressure zone of the second injector 13. After the two steam paths are mixed, they flow through the diffuser to reduce speed and increase pressure, forming medium-pressure refrigerant steam. Then, they enter the second compressor 6 to increase pressure and temperature. The fuel provides the driving heat load through the internal combustion engine 1, the high-temperature heat medium provides the driving heat load through the high-temperature heat exchanger 3, and the air and gas carry away the emission heat load through the inlet and outlet processes. The low-temperature heat medium provides the low-temperature heat load through the evaporator 12, and the heated medium obtains the medium-temperature heat load through the heater 8. The mechanical energy output by the internal combustion engine 1 is used to power the compressor 2 and the second compressor 6, or the mechanical energy output by the internal combustion engine 1 is used to power the compressor 2, the second compressor 6, and the external environment, or the internal combustion engine 1 and the external environment jointly provide power to the compressor 2 and the second compressor 6, forming an energy-carrying internal combustion engine type combined cycle heat pump system.
