摘要/Abstract

摘要： 开展了脱硫废水旋转雾化蒸发实验，研究了该技术对废水水质和烟气参数的适应性，分析了优化废水蒸发效果的方法。结果表明，旋转雾化蒸发技术对废水盐含量（TDS）、悬浮物含量（SS）、烟气温度和烟气粉尘含量等有很强的适应性。在适当的实验条件下，当废水含盐量高达200000 mg/L，悬浮物含量高达6%，烟气温度≥300 ℃，或烟气粉尘含量高达30 g/m³时，蒸发塔出口和底部灰分的含水率均低于2%，废水蒸发效果良好。此外，增加气液比或提高雾化器转速可有效降低蒸发塔出口和底部灰分的含水率，可用于对废水蒸发进行优化。

Abstract: In this study, the experiments on rotary atomization evaporation of desulfurization wastewater were conducted. The adaptability of this technology to wastewater quality and flue gas parameters were studied, and the methods to optimize the performance of evaporation were analyzed. The results show that the rotary atomization evaporation technology for desulfurization wastewater are highly adaptable to the total dissolved solids (TDS) and suspended substance (SS) of wastewater, as well as the temperature and dust concentration of flue gas. Under appropriate experimental conditions, it shows great evaporation effect in which the moisture contents of dusts from both the outlet and bottom of the evaporation tower can be reduced to below 2%, no matter whether TDS reaches as much as 200000 mg/L, SS reaches 6%, temperature≥300 ℃, or dust concentration reaches as much as 30 g/m³. In addition, increasing the gas liquid ratio or the sprayer rotate speed can effectively lower down the moisture contents, which makes it feasible to be applied for the optimization of wastewater evaporation.

Key words: desulfurization wastewater, rotary atomization, adaptability, zero discharge, wastewater quality, flue gas parameter
