摘要

实验搭建了一块120 m2的浅滩鼓泡浓海水晒盐池，盐池中含9120个直径为1 mm的鼓气孔，采用额定流量为420 m3·h-1的鼓风机鼓泡。测定了鼓泡池及1 m2对照盐池液位、温度、波美度、环境温湿度的变化，分析了气象条件和鼓气量对蒸发量的影响。研究表明，从上午12点至下午3点鼓泡晒盐效果最佳，在最佳条件下比对照池每小时可多蒸发120 kg水蒸气，但通过鼓气直接带走的水蒸气量不足8.7 kg，漂浮的气泡使盐池表面积增加50%~60%，多蒸发约50%的水蒸气，其余的水蒸气通过其他方式蒸发。与传统晒盐方法相比，浅滩鼓泡晒盐具有更快的蒸发速率，若能显著降低鼓泡管路成本和能耗，将具有较好的应用前景。

Abstract

A 120 m2 of shoal bubbling pool was built to evaporate concentrated seawater for solar salt. The pool contained 9120 aeration with diameter of 1 mm. The blower created bubbles with rated flow rate at 420 m3·h-1. The temperature

Baume degrees of concentrated seawater

the environmental humidity were measured per an hour

the effects of temperature

humidity

air flow rate on the evaporation was discussed. The results showed that the bubbling evaporation works efficiently from 12:00 p.m. to 15:00 p.m. At the optimum conditions

the bubbling pool evaporated 120 kg more than that control pool. The blowing air only taken away water vapor less than 8.7 kg. The floating bubbles increased the pool surface area around 50%—60%

which means that the same percent of the water evaporation was raised; the rest was evaporated by other ways，like droplet. Having a faster evaporation rate than the traditional solar salt

the shallow bubbling solar salt method has a promising application prospection the premise of the costs of equipments and operation having being lowered.
