                                                                                                                                                                        •   分子蒸馏是一种特殊的液--液分离技术,它不同于传统蒸馏依靠沸点差分离原理,而是靠不同物质分子运动平均自由程的差别实现分离。
                                                                                                                                                                            当液体混合物沿加热板流动并被加热,轻、重分子会逸出液面而进入气相,由于轻、重分子的自由程不同,因此,不同物质的分子从液面逸出后移动距离不同,若能恰当地设置一块冷凝板,则轻分子达到冷凝板被冷凝排出,而重分子达不到冷凝板沿混合液排出。这样,达到物质分离的目的。
                                                                                                                                                                            分子蒸馏设备在沸腾的薄膜和冷凝面之间的压差是蒸汽流向的驱动力,对于微小的压力降就会引起蒸汽的流动。在1mbar下运行要求在沸腾面和冷凝面之间非常短的距离,基于这个原理制作的蒸馏器称为短程蒸馏器。短程蒸馏器(分子蒸馏)有一个内置冷凝器在加热面的对面,并使操作压力降到0.001mbar。
                                                                                                                                                                            短分子蒸馏装置的蒸馏过程是:物料从蒸发器的顶部加入,经转子上的料液分布器将其连续均匀地分布在加热面上,随即刮膜器将料液刮成一层极薄、呈湍流状的液膜,并以螺旋状向下推进。在此过程中,从加热面上逸出的轻分子,经过短的路线和几乎未经碰撞就到内置冷凝器上冷凝成液,并沿冷凝器管流下,通过位于蒸发器底部的出料管排出;残液即重分子在加热区下的圆形通道中收集,再通过侧面的出料管中流出。
