近五年来出现了一种新型结构的冷却塔,即喷射式冷却塔。其主要特点是不用常规基本部件,如:通风机、电动机及填料层。同时,也出现了有显著改进的第二代冷却塔。图1为该冷却塔的作用原理。通过机组进口处喷嘴所引入的冷却水来诱导所需的大量风量。空气和水有效的混合,不必设置填料便能进行蒸发。冷却水落入水槽,然后由冷水泵抽出进行再循环。为了确保喷嘴良好地工作,水经过双过滤系统过滤。饱和的回风中带入的水滴由挡水板除去,回风通过导向板向上排出。这是通过一单独设置在冷却塔外的动力,即冷水泵来实现的。 In the past five years, a new type of cooling tower has emerged, namely the jet cooling tower. Its main feature is that it does not use conventional basic components such as fans, motors and filler layers. At the same time, there have also been significant improvements in second-generation cooling towers. Figure 1 shows the principle of the cooling tower. The required amount of air is induced by the cooling water introduced by the nozzle at the inlet of the unit. The effective mixing of air and water allows evaporation without the need for fillers. The cooling water falls into the sink and is then pumped out of the cold water pump for recycling. In order to ensure that the nozzles work well, the water is filtered through a double filtration system. The water droplets brought into the saturated return air are removed by the water deflector, and the return air is discharged upward through the guide plate. This is achieved through a separate set of power outside the cooling tower, namely a chilled water pump.
