Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0044] like Figure 1-Figure 2 Shown is a naturally ventilated dry-wet combined cooling tower with air precooling and winter antifreeze functions. The tower body 1 adopts a hyperbolic structure and is supported on the ground by a support structure 6. The support structure 6 is an "X"-shaped column or a "person" "Shaped column; the dry-cooling section and the wet-cooling section are integrated vertically in the tower body 1, and the dry-cooling section is located above the wet-cooling section, so that the installation height of the dry-cooling section equipment is higher than that of the dry-cooling section equipment in traditional indirect air cooling. The dry cooling section includes a dry cooling ...

Abstract

The invention relates to a natural ventilation dry-wet combined cooling tower with air precooling and winter freeze preventing functions. A dry-cooling section and a wet-cooling section are integrally arranged in the cooling tower in the perpendicular direction; the dry-cooling section comprises a dry-cooling unit, and a cooling triangle is arranged for wall-type heat exchange between air and circulating water; the wet-cooling section sequentially comprises a water distribution area, a packing area, a rain area and a water collecting tank from top to bottom, and an air-circulating water mixed heat exchange mode is adopted. A water side flowing system comprises a circulating water distribution system and a precooling system. According to the cooling tower, the operation modes including the single dry-cooling operation mode, the single wet-cooling operation mode, the dry-wet combined serial operation mode, the dry-wet combined parallel operation mode and the precooling dry-cooling operation mode of the cooling tower can be flexibly selected according to the actual conditions such as the local weather conditions and the on-site working conditions, therefore, continuous, safe and efficient operation of the cooling tower is guaranteed, water can be saved, the low tower outlet water temperature can be achieved at high temperature in summer, and the freeze problem of the dry-cooling unit can be effectively prevented in winter.

Description

technical field [0001] The invention belongs to the technical field of cooling towers, in particular to a naturally ventilated dry-wet combined cooling tower with the functions of air precooling and winter antifreeze. Background technique [0002] In the production fields of electric power, petrochemical, metallurgy, pharmaceuticals, etc., the heat generated in many production links must be dissipated in time to ensure the continuous and efficient operation of the production process. [0003] Taking a thermal power plant as an example, the condenser is a device that condenses the exhaust steam of the steam turbine into liquid water. Its cooling effect, including cooling rate and condensation temperature, is an important indicator for evaluating the economics of a thermal power plant and is directly related to the power generation efficiency of the generating set. . The excellent cooling efficiency of the condenser can promote the efficient utilization of energy and promote ...
