MVR蒸发工艺在氯化铵废水处理中的应用及经济分析

介绍了蒸汽机械再压缩式蒸发器的工作原理及工艺流程,并与三效蒸发、四效蒸发两种蒸发方式的运行费用进行了对比,体现其明显的节能效果。结果表明:从氯化铵废水中每蒸发出1 t水,相对于四效蒸发器,MVR蒸发器可以节省60.72%的标准煤。

Application and Economic Analysis of NH4Cl Wastewater Treatment by MVR Evaporation Craft

The working principle and flow path of a new type evaporator with mechanical vapor recompression evaporator was introduced.Its running costs were compared with that of the triple-effect evaporation process and that of the four stages evaporator system.This process showed obvious energy-saving results： relative to the four stages evaporator,MVR evaporator can save 60.72 % of standard coal in 1 t water evaporation from the ammonium chloride wastewater.
