| 摘 要： | 实验主要研究了电渗析浓盐水蒸发结晶规律,对氯化钠、氯化钾、低钠盐结晶工艺进行了比较,结果表明:浓盐水蒸发浓缩首先析出氯化钠,经过冷却结晶析出氯化钾,再次蒸发结晶析出低钠盐的生产工艺路线最具有市场化前景,经济价值较高。

| Abstract: | The law of brine evaporative crystallization by electrodialysis was mainly researched by experiment, which compared with the crystallization process of sodium chloride, potassium chloride and low sodium salt. The results showed that sodium chloride separated out first in the process of brine evaporation and concentration. The potassium chloride separated out after coiling crystallization. Then the low sodium salt separated out in the evaporation crystallization once again. This production process had the most market prospects and higher economic value. |
