Description

Technical fields:

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

[0002] People need cold / heat / steam / power in their lives and production processes. Using heat pump technology to obtain cold / heat / steam / power is an important means to achieve efficient and high-value energy utilization. In practical applications, it is necessary to comprehensively consider the heat pump's 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 fuels in refrigeration, heating, steam production, and power generation, and leveraging their leading role as high-quality energy sources, presents a significant technological challenge.

[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 fundamental principles of simple and efficient use of high-quality fuels for refrigeration / heating / steam production / power, this invention presents a gas turbine combined cycle heat pump system with integrated technology, a reasonable process, a simple structure, and optimized performance index.

Detailed implementation method:

[0045] 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.

[0046] Figure 1 The gas turbine-type combined cycle heat pump system shown is implemented as follows:

[0047] (1) Structurally, it mainly consists of a compressor, combustion chamber, gas turbine, steam generator, second steam generator, second compressor, ejector, heater, booster pump, second booster pump, throttle valve, evaporator, and second ejector; it has an external air passage connected to compressor 1, compressor 1 has an air passage connected to combustion chamber 2, an external fuel passage connected to combustion chamber 2, combustion chamber 2 also has a gas passage connected to gas turbine 3, gas turbine 3 also has a gas passage connected to steam generator 4 and second steam generator 5 and then connected to the outside, second compressor 6 has a refrigerant vapor passage connected to low-pressure steam inlet of ejector 7, steam generator 4 has a steam passage connected to high-pressure steam inlet of ejector 7, and ejector 7 also has a medium-pressure refrigerant vapor passage. The steam passage is connected to the heater 8. The heater 8 also has a condensate pipeline connected to the steam generator 4 via the booster pump 9. The heater 8 also has a condensate pipeline connected to the second steam generator 5 via the second booster pump 10. The heater 8 also has a condensate pipeline connected to the evaporator 12 via the throttle valve 11. The second steam generator 5 has a steam passage connected to the high-pressure steam inlet of the second ejector 13. The evaporator 12 also has a refrigerant steam passage connected to the low-pressure steam inlet of the second ejector 13. The second ejector 13 also has a medium-pressure refrigerant steam passage connected to the second compressor 6. The heater 8 also has a heated medium passage connected to the outside. The evaporator 12 also has a low-temperature heat medium passage connected to the outside. The gas turbine 3 connects to the compressor 1 and the second compressor 6 and transmits power.

[0048] (2) In terms of process, external air flows through compressor 1 to increase pressure and temperature before entering combustion chamber 2. External fuel enters combustion chamber 2, where fuel and compressed air mix and burn to form high-temperature gas. This gas then enters gas turbine 3 to reduce pressure and perform work. The gas discharged from gas turbine 3 flows through steam generator 4 and second steam generator 5 to gradually release heat and reduce temperature before being discharged to the outside. The refrigerant vapor discharged from second compressor 6 is supplied to injector 7. The steam generated by steam generator 4 enters injector 7 through high-pressure steam inlet. The high-pressure steam flows through nozzles to reduce pressure and increase speed, forming low pressure. The refrigerant vapor discharged from second compressor 6 is drawn into the low-pressure zone of injector 7. After the two steam streams mix, they flow through diffuser to reduce speed and increase pressure, forming medium-pressure refrigerant vapor, which is then supplied to heater 8. The refrigerant vapor enters heater 8 to release heat and condense. It then splits into three streams: the first stream flows through booster pump 9 to increase pressure before entering steam generator 4 to absorb heat and vaporize; the second stream flows through second booster pump 10 to increase pressure before entering second steam generator 5 to absorb heat and vaporize. The third stream flows through the throttle valve 11 to reduce pressure and temperature before entering the evaporator 12 to absorb heat and vaporize. The steam generated by the second steam generator 5 enters the second ejector 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 ejector 13. After the two streams of steam mix, 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 combustion, the low-temperature heat medium provides the low-temperature heat load through the evaporator 12, and the air and gas carry away the exhaust heat load through the inlet and outlet processes. The heated medium obtains the medium-temperature heat load through the heater 8. The mechanical energy output by the gas turbine 3 provides power to the compressor 1 and the second compressor 6, or the mechanical energy output by the gas turbine 3 provides power to the compressor 1, the second compressor 6, and the external environment, or the gas turbine 3 and the external environment jointly provide power to the compressor 1 and the second compressor 6, forming a gas turbine type combined cycle heat pump system.
