超大型海水冷却塔盐沉积影响数值模拟研究

Abstract

Abstract: A three-dimensional numerical simulation model for salt water cooling tower was established to study the characteristics of drifts and salt deposition in nuclear power project. In the model, site meteorological data, design parameters of cooling tower, general layout and environmental characteristics are considered. The results show that when the natural wind direction is parallel to the tower row, two hot air streams are superimposed on each other as one, which is beneficial to reducing the influence of drifts and salt deposition in the environment. The drifts with particle size greater than 550 μm can not escape from the outlet of cooling towers. For normal operation of 2 nuclear power units at the same site, the salt deposition will not cause damage to plants.

Key words: drifts, salt deposition, salt water cooling tower, natural wind, numerical simulation
