硝酸钠溶液余热预蒸发除氯离子技术改造及应用

Sodium Nitrate Solution Waste Heat Pre-evaporation Removing Chloride Ion Technical Innovation and Application

通过对硝盐生产蒸发工序进行技术改造,利用余热预蒸发除氯离子技术合理回收蒸发产生的余热,有效降低溶液中Cl-含量及其对设备的腐蚀,不断提高产品品质,还将生产中的废"汽"、"水"得到了回收利用,杜绝生产外排,实现清洁生产。

Based on nitrate production technical innovation evaporation process, waste heat evaporation and the chloride ion technology was used to conduct reasonable recovery of waste heat produced by the evaporation, which effectively reduced the content of CI - in the solution and its corrosion on equipment, continuously improved product quality, the production of waste “steam”, “water” had been recycled, eliminated production outside, implemented cleaner production.
