摘要
湿法氧化脱硫法中为保证脱硫效率需要定期排放一定量脱硫废液,废液中大量副盐会对环境造成极大污染。本文提出使用喷雾干燥器干燥脱硫废液的思路,通过分离脱硫液副盐,以减轻脱硫废液直接排放造成的环保压力。
In Sodium Desulfurization, some waste liquor containing mass of secondary salt, is discharged to maintain the efficiency of desulfurization. This article provided a spray drying method of removing salts from waste liquor from Sodium Desulfurization to alleviate the pressure of environmental protection caused by directly discharging waste liquor of Sodium Desulfurization.
