Title:
COMBINED CYCLE POWER DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/238222
Kind Code:
A1
Abstract:
A combined cycle power device. A condenser (9) is provided with a condensate pipeline which is in communication with a hybrid evaporator (10) by means of a circulation pump (5); an expander (1) is provided with a low-pressure steam passage which is in communication with the hybrid evaporator (10) by means of a high-temperature evaporator (8); the hybrid evaporator (10) is also provided with a low-pressure steam passage which is in direct communication with a compressor (3) and is in communication with the condenser (9) by means of a third expander (4); the compressor (3) is also provided with a steam passage which is in communication with a high-temperature heat exchanger (7); the condenser (9) is also provided with a condensate pipeline which is in communication with the high-temperature evaporator (8) by means of a second circulation pump (6), and then the high-temperature evaporator (8) is further provided with a steam passage which is in communication with a second expander (2); the second expander (2) is also provided with a steam passage which is in communication with the high-temperature heat exchanger (7); the high-temperature heat exchanger (7) is also provided with a steam passage which is in communication with the expander (1); and the high-temperature heat exchanger (7) is also provided with a heat source medium passage which is in communication with the outside, the condenser (9) is also provided with a cooling medium passage which is in communication with the outside, and the expander (1) is connected to the compressor (3) and transmits power, so as to form the combined cycle power device.
