Abstract
机械蒸汽再压缩(MVR)作为目前最先进的蒸发结晶技术得到广泛关注和应用,本文结合过热蒸汽干燥技术的优势,提出一种耦合过热蒸汽干燥的MVR蒸发结晶干燥系统。基于EES软件建立数值模型,通过系统仿真的方法分析闪蒸压力pflash、进料浓度c0、循环倍率CR、换热温差ΔTmhex等对压缩机能耗Wcomp和系统能效系数COP、下降管结晶盐含水率的上限值ω和换热器UA值的影响情况。结果表明:耦合过热蒸汽干燥的MVR系统相比常规系统具有更高的COP、更低的Wcomp,并且能够获得干燥的结晶盐;循环倍率CR增大,压缩机压比π降低,有利于提高COP和降低Wcomp,但同时换热器UAmhex值会增大,设备成本增加;系统COP随pflash的变化关系与循环倍率CR有关,CR较低时,随Pflash的增大,系统COP增大,CR超过某一定值,随着pflash的增大,系统COP呈先升后降趋势,其最大值在pflash为40~50kPa;进入干燥器的下降管结晶盐含水率的上限值ω与进料浓度c0有关,随进料浓度c0的升高而增大;ΔTmhex对MVR系统性能有显著的影响,ΔTmhex每增大1K,COP平均降低5.6%、Wcomp平均升高5.8%、UAmhex平均减少14.4%,ω平均升高1.7%
