Abstract

The invention discloses an indirect air-cooled tower, which comprises a tower body, cooling fan sections and a controller, wherein the cooling fan sections are arranged at the bottom of the tower body in a surrounding manner; each cooling fan section comprises at least one cooling triangle composed of a radiator and a shutter; each shutter is composed of an upper window body and a lower window body which are connected with each other and both are connected with a transmission unit; the transmission units are connected with one another in parallel and then connected with the controller; each transmission unit comprises an actuator and a linkage rod connected with the actuator; each linkage rod is connected with blades of the corresponding shutter through a crankshaft. The indirect air-cooled tower disclosed by the invention has the beneficial effects that a temperature measurement component can effectively monitor the tube bundle temperature of the radiators, the sectional opening and closing of the shutters can be realized by the transmission units, drastic heat exchange between cold air and freezable parts on upper tube bundles or lower tube bundles of the radiators can be avoided, frozen damage of the tube bundles of the radiators is prevented, normal operation of a system is ensured, the freezing protection of the radiators in the air-cooled tower in winter is guaranteed, and the service life of the radiators is prolonged.

Description

technical field [0001] The invention relates to the technical field of indirect air cooling, in particular to an indirect air cooling tower. Background technique [0002] With the mass adoption of indirect air-cooling systems in thermal power plants, many problems always arise in the use of indirect air-cooling systems. At present, the traditional indirect air cooling system in which the radiators are arranged vertically generally adopts the control of the temperature of the outlet water at the lower part of the radiators to achieve the purpose of antifreezing. However, when the ambient temperature is low, in the indirect air cooling system, the circulating water in the radiator finned tubes of the indirect air cooling tower is likely to freeze and cause the finned tubes to burst, which leads to frequent radiator freezing accidents in the indirect air cooling unit, which is serious When the water cycle is interrupted, the intercooling system and the unit are out of operatio...
