The outlet of water mixer is connected with the entrance of mixing tank.
Exhaust steam pipeline is communicated with water seal arrangement and emergent exhaust outlet.
Further include outlet conduit, the outlet of mixing tank is connected with one end of outlet conduit, the other end of outlet conduit
It is connected with extraneous oxygen-eliminating device.
Regulating valve is provided on cooling water pipeline.
The nozzle is high speed nozzle.
The utility model has the advantages that：
Exhaust steam residual heat retracting device is arranged when specific operation surely by thermal power plant described in the utility model, and cooling water is sprayed through nozzle
It is mapped in venturi steam heater, makes to form negative pressure in negative pressure cavity, to make the steam exhaust in exhaust steam pipeline through steam exhaust connecting tube
Road is drawn into venturi steam heater, and then heat exchanges heat to cooling water, after heating through venturi steam heater
