摘要(Abstract)：

根据雾化冷却原理,建立了80 t/h试验用逆流式无填料喷雾冷却塔,并通过4个工况的试验分析了进塔空气干湿球温度对喷雾冷却塔冷却效果的影响,结果表明:当进塔空气干球温度增加2℃时,冷却温差仅减小0.2℃,冷却效率仅减小0.8%;当进塔空气湿球温度增大1.8℃时,冷却温差减小0.8℃,冷却效率减小13.4%;进塔空气湿球温度对喷雾冷却塔的冷却效果影响较大。
According to the principle of atomization cooling,a 80t/h experimental counter-flow no-padding spraying cooling tower was established.And through four experimental conditions the influence of the inlet air dry-bulb /wet-bulb temperature on cooling effect in spraying cooling tower was analyzed.The results showed: when inlet air dry-bulb temperature increased by 2℃,the cooling range reduced by only 0.2℃ and the cooling efficiency only reduced by 3.2%,when inlet air wet-bulb temperature increased by 1.8℃,the cooling range reduced by 0.8℃ and the cooling efficiency reduced by about 13.4%,which showed that the inlet air wet-bulb temperature had a larger impact on the cooling effect than that of the inlet air dry-bulb temperature in spraying cooling tower.
