Antifreeze Numerical Study on Natural Draft Wet Cooling Tower

As the lower temperature of northern China in winter,cooling towers are easy to be frozen,so some anti-freeze measures must be taken.Using the FLUENT software simulation,this article analysis to obtain the effect of water inlet temperature on water temperature of different characteristic planes,and further simulates the flow field variation in the cooling tower after installing windshield of different layers.The calculation results indicated that:(1) when other condition of operating conditions remain unchanged,with the rise of water inlet temperature,the minimum water temperature of different characteristic planes in tower rises;(2)Adding certain layers of windshield can make the air temperature field of the bottom surface of the fill and air inlet gradually towards equalization,to prevent the cooling tower from being frozen;(3)When water inlet temperature respectively were 17.80 ℃,21.95 ℃,26.77 ℃ and 30.04 ℃,installing respectively 4,3,2,1 layers of windshield can effectively prevent the cooling tower from being frozen.
