摘　　要：针对蒸发处理核电废水工艺中的雾沫夹带问题,分析提出了选用筛板塔作为洗涤净化设备,利用蒸汽冷凝液部分回流在塔板上与蒸汽逆流接触,降低蒸汽再次夹带液滴的盐分浓度,从而使蒸馏液中含盐量大大减少。并模拟核电站硼回收系统蒸发单元进行中试试验,结果表明筛板塔作为蒸发净化设备,可有效提高蒸发单元的净化效率。In order to solve the problem of entrainment in the process of evaporating nuclear wastcwatcr, we make the equipment selection analysis and find that sieve plate tower can be a good choice. Then we simulate the real process of evaporating nuclear wastewater, compared with the sieve plate test tower, and obtain the same conclusion that sieve plate towers can meet the demand of separation requirements.
