A system, utilizing mixed component working media for low temperature heat source thermoelectric conversion, comprises a steam generator (8) provided therein from top to bottom with a spray device (7), first heater (9-1) and second heater (9-2). A thermal well (1), containing the mixed component working media, is connected to the spray device (7) via a pipeline of a pressurized liquid pump (11). A steam drying device (6), arranged at an upper portion of the steam generator (8), is connected to a gas inlet terminal of a turbine engine (5) via a pipeline. The turbine engine (5) is connected to an electric generator (4) and comprises a gas exhaust terminal connected to a mixer (3) via a pipeline. A backflow device (10) is arranged at a lower portion of the steam generator (8) and connected to the mixer (3) via a pipeline. The mixer is connected to a condenser (2). A method utilizing mixed component working media for low temperature heat source thermoelectric conversion can precisely control a flow ratio of a gas working medium and a liquid working medium in the backflow device, enabling the liquid working medium to fully absorb the gas working medium and liquidize the same, thereby increasing circulation efficiency of a system and improving a work condition of the turbine engine. The system is simple in structure, low in costs, and simple to operate. |
