Abstract

In this paper, the effect of using three drift eliminators with a different number of waves in a constant total length on compensation water flow rate and cooling efficiency of cooling tower and collection efficiency and air pressure drop of drift eliminator is investigated. These drift eliminators were made of galvanized iron in three models: type A with one wave, type B with two waves, and type C with three waves. The main purpose of this study is to investigate the effect of using drift eliminators on the performance of the cooling tower. Accordingly, experiments were performed on the laboratory cooling tower under constant environmental conditions in terms of temperature and humidity, and parameters including air mass flow rate, water mass flow rate, and inlet water temperature to the tower were assumed as constant. The results of this study show that the use of these types of drift eliminators can increase the cooling efficiency of the cooling tower by 18.5% and reduce the compensatory water flow rate of the cooling tower by 20%. On the other hand, the use of these drift eliminators increases the air pressure drop by 70% per wave and the collection efficiency of the drift eliminator by 48%.
