Abstract
The invention is suitable for the technical field of waste steam recovery, and discloses an energy-saving steam turbine unit waste steam waste heat recovery system. The system comprises a steam turbine unit, a waste steam separation system, a waste steam waste heat recovery system, an ejector, a water pump, a hot water supply port and a hot water return port; the hot water supply port communicates with the steam turbine unit; the waste steam separation system comprises a flash tank, a condensate water tank and a water cooling tank, the ejector comprises a first ejector and a second ejector, the first ejector and the water cooling tank are connected with the condensate water tank, and the condensate water tank is connected with the hot water return port; and the waste steam waste heat recovery system comprises a recovery tank and a pressurizing condenser, the recovery tank comprises an air inlet, an air outlet, a water outlet, an air valve and a spraying pipe, the air inlet is connected with the flash tank, the air outlet is connected with the pressurizing condenser, and the water outlet and the pressurizing condenser are connected with the hot water return port. According to the system, waste steam of multiple different output turbines can be recycled, pipeline laying is reduced, economic benefits are improved, meanwhile, the flash evaporation amount of high-pressure condensate water is reduced, and the recycling difficulty is reduced.
