Description
Technical field
The utility model relates to a kind of direct air cooling system of power plant.
Background technology
In China northern territory, Direct Air-cooled Unit application is more.Because this region temperature Change in season is large, make the economy of steam turbine also larger.Blower fan can adapt to the change of temperature easily, quickly, make steam turbine be in metastable running status after adopting speed change.At present, the speed change measure of Direct Air-cooled Unit mainly contains frequency control and double speed two kinds.From practical operation situation analysis, domestic Large Copacity Direct Air-cooled Unit is all adopt frequency control axial flow blower, frequency control axial flow blower needs the adjustment being realized rotation speed of fan by frequency converter, speed control device is relatively many, weight is also large, system complex, also needs other installation space to arrange frequency converter.
Summary of the invention
The utility model provides a kind of succinct direct air cooling system stably, and what the axial flow blower arrangements for speed regulation solved in existing direct air cooling system existed takes up room greatly and the technical problem of system architecture complexity.
The utility model solves above technical problem by the following technical programs:
A kind of succinct direct air cooling system stably, comprise steam exhaust device, steam exhaust device is connected together by blow-off line and air cooling tubes condenser, air cooling tubes condenser is provided with condensate water header, condensate water header is connected together by the condensate tank in condensing water conduit and steam exhaust device, and the motor that the fan bridge of air cooling tubes condenser is arranged is linked together by permanent-magnet speed governor and axial flow blower.
Axial flow blower is provided with ventilating duct.
The conductor rotor of permanent-magnet speed governor of the present utility model is fixed on motor output shaft, p-m rotor is fixed on bearing axle, YE controls speed adjusting gear, during startup, conductor rotor is rotated, and produces relative motion, utilize electromagnetic induction principle with p-m rotor, realize motor drive shaft flow fan by magnetic force transmitting torque, and regulate electromagnetic intensity to realize frequency control by control p-m rotor and conductor rotor coupling distance.
The utility model patent system is simple, easy for installation, easily control, and can greatly reduce the vibration of air cooling system, more energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of succinct direct air cooling system stably, comprise steam exhaust device 1, steam exhaust device 1 is connected together by blow-off line 2 and air cooling tubes condenser 3, air cooling tubes condenser 3 is provided with condensate water header 5, condensate water header 5 is connected together by condensing water conduit 6 and the condensate tank in steam exhaust device 1, and the motor 8 that the fan bridge 7 of air cooling tubes condenser is arranged is linked together by permanent-magnet speed governor 10 and axial flow blower 9.
Axial flow blower 9 is provided with ventilating duct 4.
The utility model relates to a kind of employing permanent-magnet speed governor connecting axle flow fan and motor, to realize the new method of operation of speed governing, replacing traditional axial flow blower adopts frequency converter and gear box combination to realize the method for operation of speed governing, be that one better can be suitable for the operation of Practical Project direct air cooling system, and there is the device saving energy consumption.
