That’s a good, and common, question. 为了回答这个问题，我们可以运行一个示例计算，做一些假设：

• 我们将围绕一个利用叶片式消声器的逆流诱导通风竞博体育来设计我们的分析。
• 我们将假设水质来自具有标准表面张力的市政供水。
• We will assume that the average and peak velocities are within a drift eliminator’s operating range (i.e., the tower was designed to account for this).
• 我们将假设液滴大小和液滴体积在整个操作时间框架内是一致的。
• 为了简单起见，我们假设该塔每天运行8小时，每周7天，每年50周（或每年2800小时）。

示例：一个4单元逆流竞博体育，设计用于在78°F（湿球温度）下从95°F到85°F冷却40000 gpm。 The existing drift eliminators are blade-style and reduce leaving drift rate to 0.002% of the circulating water flow. 因此，40,000 * 0.002% = 0.80gpm。 That’s 48.0 gallons per hour * 2,800 hours per year = 134,400 gallons per year.

The next-level drift eliminator upgrade would be to the 基本蜂窝样式, reducing leaving drift rate to 0.001% of the circulating water flow. 因此/cooling-tower/counterflow-cellular-drift-eliminators/?model_type=3884e, 40000 * 0.001% = 0.40gpm。 That’s 24.0 gallons per hour * 2,800 hours per year = 67,200 gallons per year.

But the best upgrade would be to an 增强的蜂窝样式, reducing leaving drift rate to as low as 0.00025% of the circulating water flow. 因此，40,000 * 0.00025% = 0.10gpm。 That’s 6.0 gallons per hour * 2,800 hours per year = 16,800 gallons per year.

So, if the owner of this tower were to upgrade his drift eliminators to the most enhanced, current technology, he could reduce drift loss by 117,600 gallons per year. That’s more than the water needed to fill 8 standard backyard swimming pools in the U.S.! And it’s not only the cost of the water that can be saved but the cost of: the water treatment chemicals that are dispelled along with the water droplets, the impact of corrosion on any metal around the tower, and the potential environmental and health-related impacts of allowing that much circulating water to dispel from the tower.

总而言之，漂移消除器升级可以产生非常快的投资回报。
