具体实施方式
下面结合附图和具体实施方式对本发明进行详细说明。
本发明一种基于紫外线消毒的蒸发冷却系统，如图1所示，包括支撑柱 2，支撑柱2两端分别连接伞状顶1和柱状壳体20；
壳体20内设置有蒸发冷却单元，蒸发冷却单元包括位于壳体20顶部的环状出风口4以及环绕壳体20外壁一周的进风口5，如图2所示，进风口5 内按照新风流动方向依次设置有环状粗效过滤器16、柱状填料17、布水单元、挡水板12和轴流风机11，
柱状填料17的底部设置有保温集水箱8，保温集水箱8和布水单元通过供水管15连接；
伞状顶1朝向支撑柱2的一侧设置有若干紫外线灯10，对空气进行消毒杀菌；
支撑柱2上固接有香薰筐3，为人们提供高品质空气。
布水单元包括与供水管15连接的布水管13，布水管13上分布有若干朝向填料17喷淋的喷嘴14。
供水管15上依次设置有净化器18、水泵19；水泵18提供动力，净化器19对水质净化。
保温集水箱8对应的壳体20上设置有水位观察口7，水位观测口7为透明状，方便在外部观测水位的高低。
保温集水箱8还设置有注水口6，通过注水口6对保温集水箱8内补水。
壳体20底部还设置有万向轮9，方便移动。
本发明蒸发冷却系统的工作过程如下：
(1)水系统工作过程
保温集水箱8中的水在水泵19的作用下，经过供水管15、布水管13 均匀喷淋在填料17上，淋水依靠重力下流润湿填料17表面，与进风直接接触进行热湿交换，未蒸发的水在重力作用下滴落流入保温集水箱8中，实现喷淋水的循环过程；
(2)风系统工作过程
新风由进风口5进入，经过粗效过滤器16过滤后，与湿润的填料17发生热湿交换，被等焓降温的空气在轴流风机11的作用下，通过环形出风口4 送出，途经香薰筐3、后经紫外线灯10消毒杀菌后，沿伞状顶1的轮廓向周围均匀送风。
本发明蒸发冷却空调的运行模式有两种：
第一种：夏季或者炎热时期，降温要求较大时，热空气由进风口5进入，先经过粗效过滤器16过滤后，与润湿填料17接触，喷淋在填料17上的水与热空气发生等焓降温过程，处理后的空气在轴流风机11的吸力作用下向上流动，最终通过环形出风口4吹过香薰筐3，经紫外线灯10消毒杀菌后，沿伞状顶1的轮廓向周围均匀送风。
第二种：非炎热季节(过渡季节或雨水较多季节)，室外环境不需要温降，关闭直接蒸发冷却单元，单独运行轴流风机11，具体操作为关闭水泵 19，实现基本的通风功能，是否开启紫外线灯10按照具体情况而定，加快空气流动满足人群舒适度要求，又节约了水资源，降低了相应的运行能耗。
本发明基于紫外线消毒的蒸发冷却系统适应于半开放环境，不仅能降温并且提高空气品质；采用伞状顶1内嵌紫外线灯10，对于空气进行杀菌消毒，采用保温集水箱8，对极端天气的降温也有明显的效果，加入香薰筐3根据需求加入不同香薰使得空气更加清新，圆柱形的壳体20占地面积更小，适用于该类半开放性场所。
