Water Balance Test, Analysis and Application of the Wet Cooling Tower

This study aims to conduct a water loss test and analysis of water used in wet cooling towers. The measuring tools and methods of the liquid level in the collecting basin are clearly guided by establishing the water balance equation. The U-type liquidometer measuring system is used to measure the liquid level of specific open container with a large surface area. The minimum resolution of the U-type liquidometer is 1 mm. The collecting basin area is 375 m2, and the detected water volume is 0.375 m³ mm^-1 liquid level. The measurement error caused by water surface fluctuation is overcame. The accuracy of the liquid level data is further improved. Under the water balance test condition, the water loss at the outlet of tower is between 26.25 m³ h^-1 and 49.36 m³ h^-1, and the loss of exceeding standard is 22.62 m³. This work determined the water balance condition of the wet cooling tower equipment and conducted a detailed analysis of water loss and the water conservation of the wet tower. Moreover, this study promote equipment manufacturing related to the mechanical draft cooling tower industry to the direction of water conservation, energy conservation and environmental protection to provide support. This approach is also widely used in the other air and water systems direct mixing heat transfer equipment.
