使用中需警惕高温工业冷却塔的这两个问题

更新时间：2022-08-26浏览：314次

 　　高温工业冷却塔是为节约用水而设计的，是工业上的巨大进步，广泛应用于塑料、电子、食品、纺织、化工、包装等行业。

　　采用涡轮增压水轮技术，利用设备原有的循环冷却水推动风机散热，废除在传统的冷却塔中用电机驱动风机的散热方式，省却机械减速装置和电机。散热系统的循环水是由冷却泵根据系统要求以特定的水压、水流量送至塔内进行热交换的，因此进塔后的水流及余压，可加以充分利用。完成送达冷却循环水按照一定的压力、流量流过水轮机组，从而使其获得输出功率，并驱动风机散热，*省去风机电机，达到免除风机电能的目的。
　　使用中常见的问题有两个，如下：
　　1、冷却能力问题
　　冷却能力是高温工业冷却塔质量的核心。重要组成部件——淋水填料，其作用是降低冷却水的水温，淋水填料产生的温降达到整个塔温降的60％～70％，可见淋水填料的质量与性能在很大程度上决定了冷却能力。
　　经常出现的问题是：用户在运行中发现冷却效果不是很好，或是冷却水的水温降越来越差；或是*丧失了冷却能力。
　　2、水量损失问题
　　损失水量是值得关注的节水运行参数，补充新水量的多少取决于冷却水循环过程中损失水量的多少。损失水量包括：蒸发损失、风吹损失、排污损失。
　 　(1)蒸发损失：在湿式冷却塔中蒸发损失是不可避免的；
　 　(2)风吹损失：风吹损失是指排出的热湿气流中有水滴被风吹飘移出塔外；
　 　(3)排污损失：排污损失是防止溶解性固体形成结垢，而由冷却水池中排泄带走的水量。实际运行中，用户对冷却水水质稳定无工序保证，造成冷却水浓缩倍数很高（浓缩倍率很低），加大排污量，增加了补充新水量。
