一、前言 1.使用冷却塔是一项重要的节能措施热工设备冷却水用量相当大,采用冷却塔降温循环使用的方法,比用水源直流供水可节省95％以上的供水量和20～80％的基建投资费用,同时还可降低电耗。 2.NBL型冷却塔结构简介冷却塔的种类甚多,本文所述为其中热工性能较好、水流通量属中小型的冷却塔:机械通风逆流式水与空气直接接触热湿交换,斜波塑料片卷材填料成交错布置,玻璃钢壳体。这 I. Preface 1. The use of cooling towers is an important energy-saving measures Thermal engineering equipment cooling water consumption is quite large, the cooling tower cooling cycle method, than the DC water supply can save more than 95% of the water supply and 20 to 80 % Of infrastructure investment costs, while reducing power consumption. 2.NBL-type cooling tower structure Description Cooling tower of many types, described in this article, which is better thermal performance, water flow is a small and medium-sized cooling tower: mechanical ventilation countercurrent water and air direct contact with heat and humidity exchange, oblique Wave plastic sheeting into a staggered packing, fiberglass shell.
