摘要
高位冷却塔是在自然通风逆流湿式冷却塔基础上改进的一种新型冷却塔。介绍了高位冷却塔的结构原理;比较了在无环境侧风以及各种常见风速下,高位冷却塔塔内外空气流场的变化。结果表明,环境侧风对高位冷却塔有不利影响,应该从消除或减少侧风对冷却塔塔内外流场对称性的破坏方面进行优化。
The high-level water collecting cooling tower is a new type of cooling tower based on natural ventilation countercurrent wet cooling tower.The structure principle of high-level water collecting cooling tower is introduced.According to the study of scholars,the changes of air flow field inside and outside the high-level water collecting cooling tower are compared in the absence of ambient crosswind and various common wind speeds.Finally,it is proposed that the environmental crosswind has a negative impact on the high-level water collecting cooling tower,and optimization researches should be carried out in the aspect of eliminating or reducing the damage of crosswind to the symmetry of the internal and external flow fields of the cooling tower.
