| 摘 要： | 对湿法PU革工厂二甲基甲酰胺(DMF)回收装置的节能问题进行探讨，对国内使用的传统双塔DMF回收装置与节能型的双塔DMF回收装置进行了比较。经计算，在同样的处理量时，后者比前者可节省热能34％，热能利用系数可达前者的1．23倍，并可以继续扩充塔数，使热能得到更有效合理地利用。这对处理低浓度的DMF废液十分经济。

| Abstract: | The energy saving problem on dimethyl formamide(DMF) recovery equipment of wet-process PU leather plant is discussed. The domestic conventional two-tower recovery equipment is compared with the energy-save two-tower recovery equipment. The calculation results show that the latter save 30% or so heat energy than the former, and the coefficient of heat energy utilization of the latter is 123% of the former. By the expanding of tower number, heat energy can be more efficiently utilized, so it is economic for the recovery of lower concentration DMF waste liquor. |
