直接蒸发冷却空调循环冷却水的臭氧净化
Ozone treatment of circulating water in direct evaporative cooling air conditioning systems
摘要：
采用气液混合泵投加臭氧，限制引风机出口臭氧浓度在0.2 mg/m3以下，在直接蒸发冷却空调样机上进行了循环水净化动态试验。32天的运行结果表明，臭氧投加量为0.03～0.09 g/（m3·h），浓缩倍数由1.5逐步提高到4.5，杀菌、缓蚀、阻垢效果明显。对该方法的工业应用提出了建议。

Abstract：
Adopting a gasliquid mixing pump for putting ozone into water and limiting the ozone concentration at outlet of draught fan lower than 0.2 mg/m3, carries out the dynamic simulation experiment on a sample equipment of direct evaporative cooling air conditioner. The operation results of 32 days show that the amount of ozone is from 0.03 g/（m3·h） to 0.09 g/（m3·h）, and that the concentration weight is improved from 1.5 to 4.5, and that the bactericidal, anticorrosion and antiscale effects are obvious. Proposes some measures for practical application.
