Siphon air cooling method and equipment for tower type solar thermal power generation device
InactiveCN102562502BImprove reliabilityReduce usageFrom solar energySteam engine plantsCollector deviceEngineering
The invention discloses a siphon air cooling method for a tower-type solar heat power generation device. A cylindrical condenser is used in the method, and the bottom and the upper end of the cylindrical condenser are respectively provided with an air inlet passage and an air outlet passage; the air inlet passage, the inner part of the cylindrical condenser and the air outlet passage form an air flue; and an exhaust steam condenser in the air flue is cooled by using the heat siphon effect. The tower-type solar heat power generation device manufactured by the method consists of a reflector array, a vertical tower, a tower top heat collector, a steam turbine and the cylindrical condenser. The device is characterized in that: the bottom of the cylindrical condenser is provided with the air inlet passage, and the upper end of the cylindrical condenser is provided with the air outlet passage; and the exhaust steam condenser of the solar heat power generation device is arranged in the cylindrical condenser. The air inlet passage, the inner part of the cylindrical condenser and the air outlet passage form the air flue with low air resistance. The invention has the advantages that: power is not required in heat siphon air cooling, cooling water is not required, the construction land can be reduced, the investment is reduced, the operating cost and the internal power utilization are reduced, and the reliability is improved. Four embodiments are shown in attached figures.
