Available large increase.
Detailed description of the invention
Fig. 1 is a kind of general structure schematic diagram of power station ventilating system of the invention.
Appended drawing reference is as follows in figure: 1- spiral case layer, 2- turbine floor, 3- middle layer, 4- generator floor, 5- refrigerating plant,
6- air outlet, the first ventilation shaft of 7-, the second ventilation shaft of 8-, 9- third venting pipeline, 10- bus tunnel, 11- ventilation opening.
The invention will be further described below in conjunction with the accompanying drawings, and following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of power station ventilating system, including the spiral case layer 1 being arranged from the bottom up, turbine floor 2, centre
It is provided with ventilation opening 11 on the division surface of layer 3 and generator floor 4, middle layer 3 and generator floor 4, ventilation opening 11 is located at middle layer 3
At the center of the division surface of generator floor 4, the division surface between the adjacent layer of other two is not connected to.
Air outlet 6 is provided on spiral case layer 1, air outlet 6 is connected with refrigerating plant 5, and refrigerating plant 5 is air-conditioning, refrigerating plant 5
The cold wind of generation enters in spiral case layer 1 by air outlet 6.Air outlet 6 is arranged in spiral case layer 1, it is ensured that low temperature and moisture
1 effect on moisture extraction of spiral case layer is more preferable.
Bus tunnel 10 is provided in middle layer 3, the cross-sectional area of bus tunnel 10 can guarantee the normal work of ventilation.Selection
It divulges information from middle layer 3 and flows into the smoothness that bus tunnel 10 guarantees air-flow, the expenses such as the piping facility of ventilation can also be reduced, have good
Economic effect.
Ventilating system takes the sequence of ventilation from bottom to top, is still equipped with ventilation shaft between wall, improves ventilating system
Fault-tolerance.Generator floor 4 is connected with middle layer 3 and spiral case layer 1 by the second ventilation shaft 8 respectively, and spiral case layer 1 passes through the
Three ventilation shafts 9 are connected with turbine floor 2.
