Vickers威格士859160DG4V30BMUH760DG4V30BMUH760下面我们举个例子带大家了解一下冷却塔工作的过程。圆形逆流式冷却塔的工作过程为例:热水自主机房通过水泵以的压力经过管道、横喉、曲喉、中心喉将循环水压至冷却塔的播水系统内,通过播水管上的小孔将水均匀地播洒在填料上面;干燥的低晗值的空气在风机的作用下由底部入风网进入塔内,热水流经填料表面时形成水膜和空气进行热交换,高湿度高晗值的热风从顶部抽出,冷却水滴入底盆内,经出水管流入主机。一般情况下,进入塔内的空气、是干燥低湿球温度的空气,水和空气之间明显存在着水分子的浓度差和动能压力差,当风机运行时,在塔内静压的作用下,水分子不断地向空气中蒸发,成为水蒸气分子,剩余的水分子的平均动能便会降低,从而使循环水的温度下降。
