Description

Technical fields:

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

[0002] High-quality fuels, typically represented by natural gas, gasoline, and diesel, are high-temperature heat sources with temperatures exceeding several thousand degrees Celsius. Whether for power applications, heating and cooling utilization, or combined heat and power systems, it is necessary to minimize irreversible temperature losses and fully leverage the leading role of high-quality fuels.

[0003] Internal combustion engine devices that utilize high-quality fuel to achieve thermal conversion have the advantage of utilizing the thermal energy of the high-temperature section of the gas. The key issue is to effectively utilize the cooling heat load and the gas emission heat load.

[0004] 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.

[0005] 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.

[0006] Based on the principle of simple and efficient use of fuel for heating / steam production / thermal power conversion, this invention presents a combined cycle cogeneration system for energy and internal combustion engines that integrates technologies, has a reasonable process, a simple structure, multiple functions, and a rationalized performance index. Summary of the Invention:

Detailed implementation method:

[0043] 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.

[0044] Figure 1 The energy-powered combined cycle cogeneration system shown is implemented as follows:

[0045] (1) Structurally, it mainly consists of an internal combustion engine, a compressor, a high-temperature heat exchanger, a high-temperature steam generator, a low-temperature steam generator, a second compressor, a heater, a booster pump, a throttle valve, an injector, a second booster pump, 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 high-temperature steam generator 4 and the low-temperature steam generator 5 before connecting to the outside. The second compressor 6 has a refrigerant vapor passage that connects to the heater 7. The heater 7 also has a condensate pipeline that connects to the low-temperature steam generator 5 via the booster pump 8. The heater 7 also has a condensate pipeline that connects to the internal combustion engine 1 via the throttle valve 9. Furthermore, a refrigerant vapor channel connects to the low-pressure steam inlet of injector 10, and a low-temperature steam generator 5 also has a steam channel connecting to the high-pressure steam inlet of injector 10. Injector 10 also has a medium-pressure refrigerant vapor channel connecting to the second compressor 6. An external liquid medium pipeline connects to the high-temperature steam generator 4 via the second booster pump 11. The high-temperature steam generator 4 then has a steam channel connecting to the high-pressure steam inlet of the second injector 12. An external heated medium channel connects to the heater 7 and then to the low-pressure steam inlet of the second injector 12. The second injector 12 also has a user steam channel connecting to the outside. The high-temperature heat exchanger 3 also has a high-temperature heat medium channel connecting to the outside. The internal combustion engine 1 connects to the compressor 2 and the second compressor 6 and transmits power.

[0046] (2) In terms of process, external air flows through compressor 2 to increase pressure and temperature, 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 gas emitted by internal combustion engine 1 flows through high-temperature steam generator 4 and low-temperature steam generator 5 and gradually releases heat, and then is discharged to the outside; the refrigerant vapor emitted by the second compressor 6 enters the heater 7 to release heat and condense, and then splits into two paths - the first path flows through booster pump 8 to increase pressure and then enters low-temperature steam generator 5 to absorb heat and vaporize, and the second path flows through throttle valve 9 to decrease pressure and temperature and then enters internal combustion engine 1 to cool cylinder liner to absorb heat and vaporize; the steam generated by low-temperature steam generator 5 enters injector 10 through high-pressure steam inlet, the high-pressure steam flows through nozzle to decrease pressure and increase speed and form low pressure, the refrigerant vapor emitted by internal combustion engine 1 is drawn into the low-pressure area of ​​injector 10, and the two steam paths are mixed. The medium-pressure refrigerant vapor is formed by slowing down and increasing pressure in the diffuser, and then enters the second compressor 6 for further pressurization and heating. The heated medium flows through the heater 7 to absorb heat and vaporize. The liquid medium is pressurized by the second booster pump 11, flows through the high-temperature steam generator 4 to absorb heat and vaporize, and then enters the second injector 12 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle to decrease pressure and increase speed to form a low pressure. The steam generated by the heater 7 is drawn into the low-pressure zone of the second injector 12. The two steam streams are mixed and then flow through the diffuser to slow down and increase pressure to form medium-pressure steam, which is then supplied to users. The fuel provides high-temperature driving heat load through the internal combustion engine 1. The air and gas carry away the emission heat load through the inlet and outlet processes. The high-temperature heat medium provides driving heat load through the high-temperature heat exchanger 3. The steam user receives a steam-type heat load. The mechanical energy output by the internal combustion engine 1 is used to power the compressor 2, the second compressor 6, and external components, forming an energy-driven combined cycle combined cycle thermal power system.

An energy-carrying internal combustion engine combined cycle cogeneration system is an energy-carrying internal combustion engine combined cycle cogeneration system according to any one of claims 1-15, wherein a high-temperature regenerator is added, the external air passage connecting the compressor (2) is adjusted to the external air passage connecting the compressor (2) and then the compressor (2) has an air passage connecting itself through the high-temperature regenerator (27), and the internal combustion engine (1) has a gas passage connecting the high-temperature steam generator (4) is adjusted to the internal combustion engine (1) having a gas passage connecting to the high-temperature steam generator (4) through the high-temperature regenerator (27), thereby forming an energy-carrying internal combustion engine combined cycle cogeneration system.
