5) the heat exchanger structure size is big, and complicacy is installed, and needs heavy construction equipment.
3, directly air-cooled
The high high-intensity load-bearing scaoffold of 30m to 50m is set, air cooling condensing heat exchanger is installed on scaoffold, and mount high power blower fan crowd; Air cooling condensing heat exchanger is made up of finned tube; Feed the steam turbine steam tail gas in the pipe, pipe is outer to be fin, with the air contact heat-exchanging; Through the forced ventilation of blower fan, make the steam cooled in the heat-exchanging tube bundle and condense.As shown in Figure 3, have following pluses and minuses:
1) do not want cooling tower.
2) water consumption not.
3) heat exchanger is the steam phase transforming heat exchange, and heat exchange efficiency is high.
4) need be provided with that platform and structural strength are high, load-bearing is big, consumptive material is huge, cost is high, accounts for totle drilling cost about 50%.
5) palpus high-altitude installation exercise, installation difficulty is big, has a big risk, and installation cost is high.
6) setting height(from bottom) is big, the operation and maintenance complex management, and maintenance cost is high.
7) the blower fan crowd is consumed energy greatly, is about 1.5%～2% of power generator group generated energy.
8) the fan operation vibration is big, and noise is big.
The utility model content
In sum, the utility model technical problem to be solved is to be provided with on the basis of cooling tower, and a kind of not water consumption is provided, not power consumption, directly cooling or claim the high-efficiency steam condensing heat-exchanger rig of gravity-flow ventilation in air.
For solving the problems of the technologies described above; The utility model air cooling condensing plant is made up of the A type heat-exchanging tube bundle unit, tube bundle support structure, steam distribution house steward, the steam distribution main that comprise the steam distribution arm; Said condensing plant adopts air directly to cool off, and the steam tail gas of steam turbine discharging directly gets into the A type heat-exchanging tube bundle unit that is placed in diverse location.
