Fill-free spray cooling tower cooling temperature difference 2 ℃ than the packing tower, cooling water up 10% year on year, smaller than the packing tower. As the cooling element of the fillerless cooling tower (high-efficiency low-pressure centrifugal atomization device) sprayed the water into 0.5mm tiny droplets, the specific surface area of the water droplets is much larger than the specific surface area of the water-dispersed film, And the water distribution is uniform, which avoids the dead zone and the ditch flow caused by the aging deformation and clogging of the packing. The cooling effect is obviously superior to the packing tower.
