Water-saving and fog-eliminating technology of cooling tower

There are several water-saving and fog-eliminating technologies for cooling towers: 1, front-end precooling technology (wet and dry parallel technology). Finned heat exchange tube bundles are installed on both sides of the upper air chamber of the water receiver. The circulating water first enters the finned tube bundle (dry type) to cool down, and the hot and humid air passing through the packing (wet type) is mixed with the dry cold air from the finned tube to become unsaturated wet air, and then it is discharged out of the tower to achieve the effect of mist elimination. 2. In 2007, Marley Company of the United States developed a new defogging technology of condensation module (gas-steam heat exchanger). The hot and humid air in the tower exchanges heat with dry cold air through the plate cross-flow gas-gas heat exchanger, which greatly reduces the moisture content of the air leaving the tower and recovers the condensed water.
