Abstract

The embodiment of the invention provides an antifreeze diversion device of an air cooling radiator of a natural ventilation cooling tower. Mainly, the air inlet of the air cooling radiator is horizontally or obliquely formed in the natural ventilation cooling tower, the air cooling radiator is placed on the air inlet, or the air cooling radiator and the air inlet are arranged with a certain included angle in between; the antifreeze diversion device is arranged in the air cooling radiator non-air-inlet area at the tower cylinder bottom of the natural ventilation cooling tower, and fed air at the tower cylinder bottom of the natural ventilation cooling tower is adjusted through the antifreeze diversion device. In winter, cold air can enter the cooling tower through the antifreeze diversion device without flowing through the air cooling radiator, and sucking force of the cooling tower is remarkably reduced. By means of the antifreeze diversion device, the natural ventilation sucking force of the air cooling tower can be effectively controlled, the windward air velocity of the air cooling radiator is adjusted, the risk that circulating cooling water in the air cooling radiator is frozen in winter is reduced, and the running safety and economy of an air cooling power generator set are improved.

Description

technical field [0001] The invention relates to the industrial field, in particular to an antifreeze guide device for an air-cooled radiator in a natural draft cooling tower. Background technique [0002] Air-cooling is the main cooling method for thermal power plants in "coal-rich and water-shortage" areas, which can be divided into direct air cooling and indirect air cooling. The main heat exchange equipment of air cooling is air cooling radiator, which is divided into direct air cooling radiator and indirect air cooling radiator. The radiator can be divided into steel, aluminum or steel-aluminum composite according to the material. Air cooling systems using natural ventilation are generally equipped with cooling towers. Cooling towers are mainly divided into reinforced concrete towers, steel structure clad aluminum plate towers, steel structure towers, steel structure clad fiberglass towers, steel cable clad aluminum towers, etc. Radiators can be arranged horizontally ...
