Abstract

The invention discloses an air cooler water film cooling strengthening device and method. The air cooler water film cooling strengthening device comprises a pipe bundle, a hanging template, a water pool, an atomizer and an airflow guide plate. The tube bundle is obliquely arranged above the water tank; the multiple hanging templates are arranged in parallel at intervals, and the tube bundle penetrates through the hanging templates. An atomizer is arranged in the water tank; the airflow guide plate is arranged among the tube bundle, the hanging template and the water tank; and an air inducing device is arranged above the air cooler. According to the device, water film cooling strengthening is achieved on the basis of a closed air cooler, in the water film cooling strengthening process, atomized water drops reach the surface of a film hanging plate, and under the action of the gravity of the water drops, airflow, the special film hanging plate form and the hydrophilic surface, the water drops are captured by the film hanging plate and rapidly stretch to generate a thin water film; according to the method, the water film vaporization efficiency and direct heat exchange on the heat exchange surface are greatly improved, efficient cooling with low water consumption is achieved, and the method has the advantages of being simple in structure, low in cost and the like.

Description

technical field [0001] The invention relates to a cooling device, in particular to a device and method for strengthening water film cooling of an air cooler. Background technique [0002] Air cooler is the abbreviation of air cooler, which is the most widely used heat exchange equipment for condensation and cooling in petrochemical, HVAC and oil and gas processing and production. Air coolers are widely used in industrial circulating cooling water. According to whether the circulating cooling water is in contact with the atmosphere, air coolers are divided into two types: open type and closed type. The open air cooler mainly absorbs heat through the evaporation of the circulating cooling water itself, and then the heat is taken out by the air to achieve the purpose of cooling. The evaporation loss of the circulating water is relatively large, which is about 1-2% of the circulating water volume. At the same time, evaporation causes The circulating water is concentrated, the w...
