摘要/Abstract

摘要： 针对高沸点升溶液蒸发过程的特点，结合蒸汽压缩机提升二次蒸汽压力和温度的实际能力，提出一种分级压缩的机械蒸汽再压缩(MVR)蒸发系统，建立了分级压缩和多级压缩MVR蒸发系统的数学模型，考察了溶液沸点升高、压缩机压缩比和一级排出液浓度等运行参数对蒸发系统能耗、蒸发器换热面积、设备成本和系统总费用的综合影响. 结果表明，分级压缩MVR蒸发系统适用于沸点升在15℃以上的物料，NaOH溶液浓缩的最优操作工况为压缩机压缩比2.0、一级排出液浓度23%(?). 相同蒸发水量下，分级压缩MVR蒸发系统可节约47.83%的系统能耗和28.75%的设备成本，比多级压缩MVR蒸发系统节能效果好.

Abstract: A hierarchical compression mechanical vapor recompression (MVR) evaporation system was proposed by taking account of the high boiling point elevation of solutions and the actual capability of steam compressors raised the temperature and pressure of secondary steam. Theoretical models were established for the hierarchical and multistage compression MVR evaporation systems and the effects of operating parameters such as the solution boiling point elevation (BPE), the compressor compression ratio and the outlet mass fraction on system energy consumption, the heat transfer area of the evaporator, the cost of equipment and the total cost of the system were investigated. The results showed that the hierarchical compression MVR evaporation system was more suitable for solutions with boiling point elevation over 15oC. Sodium hydroxide solution was used for a case study. The optimal operating conditions were the first stage effluent concentration 23%(?) when the compressor compression ratio 2.0. Under such conditions, the same amount of water evaporation were completed, the hierarchical compression MVR evaporation system reduced energy consumption by 47.83% and equipment cost by 28.75%, better than the multistage compression MVR system in saving energy effect.
