蒸发过程解析蒸发过程解析analysis of evaporation process乙hengta guoehengJ一ex-蒸发过程解析(analysis of evaporation pro-cess)为实现蒸发过程优化而进行的数学解析。蒸发是使溶液中的溶剂在沸腾状态下部分汽化并将蒸汽移除，从而使溶质浓度提高的过程，为有色金属提取冶金单元操作之一当溶液浓缩超过溶质的饱和浓度时，便有结晶溶质析出，浓缩、结晶多数是物理过程，但有时是化学分解反应的结果。因此，蒸发与反应及结晶过程有密切联系，如钨酸钱溶液蒸发浓缩，分解出氨并有仲钨酸钱析出。有色金属冶金生产的蒸发过程常伴有化学反应过程。简单的蒸发是间歇式的，用直接火或电加热。多数情况下，由于蒸发处理量大，要求有较大的传热面，需要用蒸汽加热，采用列管式或夹套式蒸发器。蒸发水量由下式计算:w一尸{}一亚! 、犷1尹加热蒸汽供热量为: Q一Dr。一〔F外。(t，一人)+w尸牛Q〕蒸发器传热面积为:QS~丁户=~一K山，式中w为蒸发水量，kg/h;，。、二，分别为原料液及完成液溶质质量分率，%;F为加料量，kg/h;I)为加热蒸汽量，kg/h;r。、:，为加热蒸汽及二次蒸汽潜热，kJ/’kg;外。为原料液的比热容，kJ/kg·K;Q、Ql为传热量及热损失，kJ/h;t。为原料液温度，K;tl为溶液沸点，K;S为传热面积，m“;K为传热系数.k]/(mZ·h·K)，山m为平均温度差，K。利用二次蒸汽加热下一效蒸发器，可节省新蒸汽，提高经济效益。多效串联使用时，最后一效抽真空以保持各效有足够的温度差，这种流程为多效蒸发，适用于蒸发量大的生产过程。计算方法与单效相似。在有结晶产生的蒸发过程，应及时排除结晶以减少其在传热面上的结垢，蒸发器附设结晶分离器。
