Fractional condensation structure of twining suitable for vacuum distillation

The utility model relates to a fractional condensation structure of twining suitable for vacuum distillation belongs to vacuum metallurgical equipment technical field. This fractional condensation structure of twining suitable for vacuum distillation, including condensate pan with be located the vapour passageway of condensate pan intermediate position, the condensate pan bottom be the inclined plane that the vapour passageway is high, the terminal surface is low, the straight line that condensate pan both ends minimum formed with the vapour passageway respectively and water flat line's contained angle be being equipped with the condensation metal bottom 5~10, the condensate pan and export condensation metal exit linkage flow guide disc or liquid metal collection device. This fractional condensation structure of twining suitable for vacuum distillation adopts multistage installation, settles the upper portion in evaporating zone territory in the vacuum furnace, prolongs the vapour passageway after the metal v
