【摘要】：通过建立高位收水冷却塔内收水单元的三维数值模型,利用Fluent对其进行了数值模拟,分析了不同挡水板位置对单元内流场、水滴飘零损失以及高位收水冷却塔通风量的影响,模拟结果表明:当挡水板的角度为45°板长为0.2m时,塔通风量最大,0m/s条件下的塔通风量达到11 920kg/s,较不加挡水板时提高8.69%,证明此时的收水装置阻力最低,效果最佳。
[Abstract]:Through the establishment of a three-dimensional numerical model of the intake unit in a high water intake cooling tower, the numerical simulation of the unit is carried out by using Fluent. The effects of different water baffle positions on the flow field, droplet drift loss and ventilation of the high water intake cooling tower are analyzed. The simulation results show that when the angle of the baffle is 45 掳and the length of the plate is 0.2m, the ventilation capacity of the tower reaches 11 920 kg / s when the maximum ventilation capacity is 0 m / s, which is 8.69 kg / s higher than that without the baffle. It is proved that the water collecting device has the lowest resistance and the best effect.
