Problems solved by technology
However, due to the large tower suction of the natural ventilation cooling tower, when the tower suction and the strong wind superimpose on the shutters, the anti-freeze curtains are closely attached to the shutters, and it is very difficult to unfold, which cannot solve the problem of unsmooth operation of the anti-freeze curtains

The invention proposes an anti-freezing device and method for an indirect air cooling system, relates to the technical field of thermal power generation, and can make full use of an existing heat dissipation triangular structure to arrange the anti-freezing device to completely or partially cover the outer surface of a radiator; and due to the optimized arrangement of the anti-freezing device, theanti-freezing device is smooth, flexible and adjustable to fold and unfold. The anti-freezing device comprises a driving device and an anti-freezing curtain; the driving device is arranged on a broadening platform; the upper end of the anti-freezing curtain is arranged at the outer side end of the broadening platform, and the bottom of the anti-freezing curtain is wound on a movable reel; the movable reel vertically falls on the outer side of a broadening platform bracket and is connected with the driving device through a traction belt; and cable wind ropes used for tightening the anti-freezing curtain are arranged on the two sides of the anti-freezing curtain, and the bottom ends of the cable wind ropes are connected with hooks arranged on the ground of the bottom of the broadening platform bracket in a hung mode. The technical scheme provided by the invention is suitable for the anti-freezing process of the radiator of the air cooling system.
Description
【Technical field】 [0001] The invention relates to the technical field of thermal power generation, in particular to an antifreeze device and method for an indirect air cooling system. 【Background technique】 [0002] The indirect air-cooling system is a surface-type air-cooling heat exchange system. The process flow is that the exhaust steam of the steam turbine is cooled by the circulating water system. Heat cooling, the cooled circulating water returns to the condenser to cool the exhaust steam of the steam turbine, and this process forms a closed circulation system. [0003] When the intercooling system is at low temperature in winter, the unit will dynamically cool and adjust according to the load. When the return water temperature of the radiator of some sectors of the intercooling system is low enough to the temperature of antifreeze protection, some or all sectors need to be cut off and removed. The fan section needs to complete the water discharge operation, because ...
