2) around filler, set up hot water ice pipe.
Domestic this measure of commonplace employing is at present promptly drawn hot-water line to a filler top (or below) from last tower water pipe, around filler, locates to form down trickle of hot water pipe net, prevents that cooling tower from freezing.Take this measure to increase the spray density of cooling tower air inlet, make air inlet be difficult for forming the ice curtain, and owing to be hot water, guaranteed filler to a certain extent around temperature be higher than apparent freezing point, not-easy-to-freeze.But because hot water is to introduce from the cooling tower return pipe; If the plant produced load is lower, perhaps night, ambient temperature was far below apparent freezing point, often the requirement of not reaching of return water temperature ice; And can descend to a certain extent through hot water temperature behind the filler, more cannot say for sure the effect of card ice.
3) set up steam pipe or heating wire at the cooling tower air inlet.
Because cooling tower needs operation all the year round, limited by factory condition and operating cost, what this method was used also is not a lot.
