The fog elimination effect is good. It has good mist elimination effect when used wet and dry, and has high water-saving performance. Mechanical ventilation tower, also called mechanical ventilation cooling tower, is the main equipment for evaporative cooling of circulating water. Its working principle is to spray hot circulating water from the top of the cooling tower and then flow into the water collection pool. At the same time, the fan blows air from bottom to top in the opposite direction to the water flow, so the water film on the filler is in extensive contact with the cold air. And a mass transfer and heat transfer process occurs, taking away the heat of the circulating water.
