AI Technical Summary
Existing closed-circuit cooling towers consume a lot of water during operation. Some of the spray water droplets pass through the water collector and are discharged into the atmosphere with the humid air, resulting in persistently high water consumption.
A heightened air duct is added to the outer casing of the cooling tower's fan, and a mesh water collection device is installed inside it. The water collection device blocks water droplets and condenses the humid air, recovering the condensate into the water tank.
It effectively reduces the water drift rate of the cooling tower, reduces water consumption, and lowers operating costs.
