Description
Technical Field
The utility model relates to an industry recirculated cooling water technical field specifically is a slant air cooling tube bank counter-current moves water film arrangement system.
Background
In the aspect of industrial circulating cooling water heat dissipation, the most common air cooling heat exchanger is a tubular heat exchanger and consists of a plurality of heat exchange tube bundles, and the top fan drives air to pass through the heat exchange tube bundles from bottom to top so as to take away heat of the heat exchange tube bundles and achieve the purpose of cooling. At present, most of heat exchange tube bundles are transversely arranged, and the occupied area is large. In order to strengthen the heat transfer of the heat exchange tube bundle, the mode of spraying water to the heat exchange tube bundle is generally adopted for auxiliary cooling, the water spraying is generally carried out by the uppermost end of an air cooler, the spraying water is flushed by the reverse airflow to take away heat on the surface of the heat exchange tube bundle, generally, because the spraying water quantity is large, the vaporization of the water is little, the sensible heat of the water is mainly utilized for heat exchange, the efficiency is not high, and the loss of the spraying water is large.
In recent years, a dry-wet combined high-efficiency air cooler based on fin water film evaporation has been developed, and the efficiency is greatly improved by using latent heat of vaporization of water (the efficiency is 500 times or more as high as sensible heat). The tube bundle obliquely arranged can effectively reduce the floor area, also reduce the gravity component of the water film, improve the adhesive capacity of the water film on the surface of the fin and facilitate the arrangement of the water film. The formation of the liquid film requires a smaller water spraying amount and a smaller water drop particle size, but the small-particle-size liquid drops are easily blown out by strong reverse air flow before reaching the surface of the tube bundle, so that a large amount of air blowing loss is caused, and meanwhile, the expected film distribution effect cannot be achieved. The liquid drops are stably attached to the surface of the fin by means of the balance of self gravity, interface friction and air resistance to form a thin liquid film, and then the liquid film is gradually vaporized under the action of air flow. The surfaces of the fins need to be alternately subjected to film distribution and evaporation, and the moving small-area water distribution can realize the optimal film distribution and evaporation effects. Therefore, the development of a movable water-saving high-efficiency film distribution system which meets the requirements of inclined plane film distribution and effectively avoids air blowing loss has important significance for the development of novel air coolers.
