For achieving the above object, the utility model adopts following technical scheme:
A kind of empty compound condenser of series connection integrated high-efficiency that steams, comprise: air cooling tubes condenser and vaporation-type condenser, the steam-distributing pipe that is communicated with the turbine discharge pipeline is communicated with the condensate water header by air cooling tubes condenser following current tube bank, described condensate water header is communicated with pumped vacuum systems by the tube bank of vaporation-type condenser adverse current, and described condensate water header is communicated with condensate tank by pipeline.
The described empty compound condenser of series connection integrated high-efficiency that steams, air cooling tubes condenser top is provided with axial flow blower.
The described empty compound condenser of series connection integrated high-efficiency that steams, the vaporation-type condenser is provided with spray system and quenching system.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
A kind of empty compound condenser of series connection integrated high-efficiency that steams be to change the tube bank of the part in traditional air cooling tubes condenser into evaporation and heat-exchange by the air cooling heat exchange, and based on the air cooling heat exchange, evaporation and heat-exchange is auxilliary; With air cooling tubes condenser sensible heat transfer and vaporation-type condenser latent heat heat exchange optimum organization: the advantage of existing air cooling tubes condenser heat exchange water saving has vaporation-type condenser heat exchange efficiency height, energy-conservation, advantage such as the condensing back pressure is low again; And system is stable, and is safe and reliable.
When 1, air cooling tubes condenser can satisfy system's needs when environment temperature is low, the vaporation-type condenser can be sentenced closed condition, and condenser is water consumption not fully.
2, when environment temperature is higher than a certain temperature, when air cooling tubes condenser can not be satisfied the demand, open the vaporation-type condenser, because of the vaporation-type condenser adopts the latent heat heat transfer mechanism, good effect of heat exchange, the condensing back pressure is low, and water consumption is little; The overall water consumption of condenser is little.
