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 gas turbine-type combined cycle heat pump system shown is implemented as follows:
[0045] (1) Structurally, it mainly consists of a compressor, combustion chamber, gas turbine, high-temperature steam generator, low-temperature steam generator, second compressor, heater, booster pump, throttle valve, evaporator, ejector, second booster pump, and second ejector; it has an external air passage connecting to compressor 1, compressor 1 has an air passage connecting to combustion chamber 2, an external fuel passage connecting to combustion chamber 2, combustion chamber 2 also has a gas passage connecting to gas turbine 3, gas turbine 3 also has a gas passage connecting to high-temperature steam generator 4 and low-temperature steam generator 5 before connecting to the outside, second compressor 6 has a refrigerant vapor passage connecting to heater 7, heater 7 also has a condensate pipeline connected to low-temperature steam generator 5 via booster pump 8, heater 7 also has a condensate pipeline connected to low-temperature steam generator 5 via throttle valve 9. Evaporator 10 is connected, and evaporator 10 also has a refrigerant vapor channel connected to the low-pressure steam inlet of ejector 11. Low-temperature steam generator 5 also has a steam channel connected to the high-pressure steam inlet of ejector 11. Ejector 11 also has a medium-pressure refrigerant vapor channel connected to the second compressor 6. An external liquid medium pipeline connects to the high-temperature steam generator 4 via the second booster pump 12. The high-temperature steam generator 4 then has a steam channel connected to the high-pressure steam inlet of the second ejector 13. An external heated medium channel connects to the heater 7 and then to the low-pressure steam inlet of the second ejector 13. The second ejector 13 also has a user steam channel connected to the outside. Evaporator 10 also has a low-temperature heat medium channel connected to the outside. Gas turbine 3 connects to compressor 1 and the second compressor 6 and transmits power.
[0046] (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 high-temperature steam generator 4 and low-temperature steam generator 5 to gradually release heat and reduce temperature before being discharged to the outside. The refrigerant vapor discharged from the second compressor 6 enters heater 7 to release heat and condense. It then splits into two paths: the first path flows through booster pump 8 to increase pressure before entering low-temperature steam generator 5 to absorb heat and vaporize; the second path flows through throttle valve 9 to reduce pressure and temperature before entering evaporator 10 to absorb heat and vaporize. The steam generated by low-temperature steam generator 5 enters ejector 11 through high-pressure steam inlet. The high-pressure steam flows through nozzle to reduce pressure and increase speed, forming low pressure. The refrigerant vapor discharged from evaporator 10 is drawn into the low-pressure zone of ejector 11. The two steam paths mix and flow through diffuser to reduce speed and increase pressure, forming medium-pressure refrigerant vapor, which then enters the second compressor 6. The heating medium is pressurized and heated, and flows through the heater 7 to absorb heat and vaporize. The liquid medium is pressurized by the second booster pump 12, flows through the high-temperature steam generator 4 to absorb heat and vaporize, and then 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 to form a low pressure. The steam generated by the heater 7 is drawn into the low-pressure zone of the second ejector 13. After the two steams are mixed, they flow through the diffuser to reduce speed and increase pressure to form medium-pressure steam and supply it to users. The fuel provides driving heat load through combustion, and the low-temperature heat medium provides low-temperature heat load through the evaporator 10. Users receive steam-type heat load. Air and gas carry away the emission heat load through the inlet and outlet processes. The mechanical energy output by the gas turbine 3 is used to power the compressor 1 and the second compressor 6, or the mechanical energy output by the gas turbine 3 is used to power the compressor 1, the second compressor 6 and the outside, or the gas turbine 3 and the outside jointly provide power to the compressor 1 and the second compressor 6, forming a gas turbine type combined cycle heat pump system.
