混合卤蒸发过程能量分析

Energy Analysis for the Evaporation Process of Mixed Bittern

对采用双效、负压、逆流连续操作工艺蒸发混合卤过程进行的能量衡算 ,提出将I效蒸发蒸汽的一部分抽出预热进I效原料可使单位蒸汽消耗量 (D/W )进一步降低的新工艺 ,D/W为 0 .6 88。

Energy balance for double effect evaporation process of mixed bittern in the condition of counter-current and negative pressure is calculated. The new process for reducting the unit evaporation consumption (D/W) is put forward. D/W is 0.688.
