摘要

针对湿式蒸发冷却塔蒸发量大、排污量大、冬季雾羽大等弊端，介绍了盘管型、填料型及复合型蒸发冷却塔气—水两相传热传质计算公式，阐明了气—水传热传质过程空气温度、湿度、焓值等参数精确计算方法。结合实时进塔空气温度、含湿量和质量流量，计算同一时间段的循环水蒸发量、排污量和补水量，结果表明：在相同相对湿度下，干球温度34℃对应的循环水蒸发量、补水量比干球温度20℃对应的量减小15%；在相同湿球温度下，干球温度34℃对应的循环水蒸发量、补水量比干球温度20℃对应的量增大48.8%。因此，蒸发冷却过程中空气参数的精确计算可实现湿式蒸发冷却塔蒸发量、补水量及排污量的实时计算及调节，并进而推进其节水消雾和节能减排优化。

Abstract

In view of the disadvantages of wet evaporative cooling tower such as large water evaporation

large sewage discharge

and large fog plume in winter

this paper summarized the calculation formulas of air parameters in the air-water two-phase heat and mass transfer for the coil type

the filling type and composite type evaporative cooling tower. Combined with real-time inlet air temperature

moisture content and mass flow

the accurate calculation method of air temperature

moisture content

enthalpy and other parameters in the process of air-water heat and mass transfer were further clarified. The water evaporation rate

discharge rate and water saving amount were calculated at the same time period. The calculation results show that under the same inlet air relative humidity

the water evaporation rate and make-up rate corresponding to dry bulb temperature of 34℃ are 15% less than those corresponding to dry bulb temperature of 20℃. Under the same wet bulb temperature

the water evaporation rate and make-up water rate corresponding to dry bulb temperature of 34℃ increase by 48.8% than that corresponding to dry bulb temperature of 20℃. Therefore

the accurate calculation of air parameters in the evaporative cooling process

could avail the real-time calculation and regulation of evaporation rate

water make-up rate

discharge rate

and promote the optimization of water saving

plume abatement

energy saving and discharge reduction for wet evaporative cooling tower.
