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.

Detailed implementation method:

[0041] 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.

[0042] Figure 1 The energy-powered combined cycle cogeneration system shown is implemented as follows:

[0043] (1) Structurally, it is mainly composed of an internal combustion engine, a compressor, a high-temperature heat exchanger, a steam generator, a booster pump, an injector, a second compressor, a heater, and a throttle valve. There is an external air passage that connects to the internal combustion engine 1 via the compressor 2 and the high-temperature heat exchanger 3. There is also 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 then to the outside. The second compressor 7 has a refrigerant vapor passage that connects to the heater 8. The heater 8 also has a condensate pipeline that connects to the internal combustion engine 1 via the throttle valve 9. The internal combustion engine 1 then has a refrigerant vapor passage that connects to the second compressor 7. There is an external liquid medium pipeline that connects to the steam generator 4 via the booster pump 5. The steam generator 4 also has a steam passage that connects to the high-pressure steam inlet of the injector 6. There is an external heated medium passage that connects to the heater 8 and then to the low-pressure steam inlet of the injector 6. The injector 6 also has a user steam passage that connects to the outside. The high-temperature heat exchanger 3 also has a high-temperature heat medium passage that connects to the outside. The internal combustion engine 1 connects to the compressor 2 and the second compressor 7 and transmits power.

[0044] (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 steam generator 4 and releases heat, and then is discharged to the outside; the refrigerant vapor emitted by second compressor 7 enters heater 8 to release heat and condense, 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, and then enters second compressor 7 to increase pressure and temperature; the heated medium flows through heater 8 to absorb heat and vaporize, and the liquid medium flows through booster pump 5 to increase pressure and then enters steam generator. Heat absorber 4 vaporizes and then enters injector 6 through high-pressure steam inlet; high-pressure steam flows through nozzle to reduce pressure and increase speed to form low pressure, and refrigerant steam generated by heater 8 is drawn into the low-pressure zone of injector 6. After the two steams are mixed, they flow through diffuser to reduce speed and increase pressure to form medium-pressure steam and are supplied to the outside; fuel provides high-temperature driving heat load through internal combustion engine 1, high-temperature heat medium provides driving heat load through high-temperature heat exchanger 3, air and gas carry away emission heat load through inlet and outlet processes, user steam carries away steam-type heat load, and the mechanical energy output by internal combustion engine 1 provides power to compressor 2, second compressor 7 and the outside, forming an energy-carrying internal combustion engine type combined cycle heat and power system.
